Houston CEO Receives Prestigious, Top National Engineering Award for Developing a Breakthrough Technology That Kills COVID-19

Monzer Hourani honored for inventing Integrated Viral Protection (IVP) biodefense indoor air technology that catches and kills actual SARS-CoV-2, the virus that causes COVID-19 (99.999%), instantaneously

HOUSTON, April 8, 2021 /PRNewswire/ — Monzer Hourani, CEO of Medistar and inventor and chairman of Houston-based Integrated Viral Protection, received Engineering News-Record‘s (ENR) Top 25 Newsmakers of the Year and ENR’s highest honor, the Award of Excellence, at ENR’s 2021 Newsmakers of the Year and Award of Excellence Luncheon April 8.


Hourani received the Award of Excellence for his lifetime achievement in structural engineering, architecture, design and real estate development, and for his most recent breakthrough invention, the Biodefense Indoor Air Protection System, proven as the only technology to “catch and kill” COVID-19 and other dangerous airborne pathogens, instantaneously in a single pass, and is also endorsed by the American Society of Mechanical Engineers.


“I am honored to receive this prestigious award and to be in such esteemed company,” said Hourani. “As soon as the pandemic began, I knew we would need a solution to bring us back to gathering indoors safely. There is no better time to embrace the significance of indoor air quality to reopen our world safely with a technology that will protect future generations.”


IVP’s indoor air biodefense technology is being rapidly deployed across the nation in medical centers, office buildings, schools, college dorms, restaurants and hotels, including the Intercontinental Hotel in Houston.


ENR salutes outstanding achievements in construction and engineering with its annual Top 25 Newsmakers, Award of Excellence and Best of the Best Projects teams. Hourani was honored as both a Top 25 Newsmaker and given the Award of Excellence. Past honorees include Vicky O’Leary, Chairwoman of North America’s Building Trades Unions, and Cris Liban, Chief Sustainability Officer for Los Angeles County Metropolitan Transportation Authority.


“The editors of Engineering News-Record have named Monzer Hourani the winner of the 2021 ENR Award of Excellence for his crusade, above-and-beyond the call of duty, to reduce COVID-19 transmission indoors through his virus-killing air filter that boosts indoor air quality — making buildings safer havens during this and future pandemics,” said Nadine Post, Editor-at-Large for ENR.


Attending the in-person and hybrid ceremony were elected officials including former Texas Governor and U.S. Secretary of Energy Rick Perry; Senators Marco Rubio and John Cornyn; and former Secretary of Housing Henry Cisneros; global health and business leaders such as Mehmet Oz (Dr. Oz) and Kim Bassett, president of Stewart Medical; and Texas A&M Chancellor John Sharp. The gala was held at the Intercontinental Hotel in Houston, the first hotel property in the world to install the technology protecting its employees and guests.


“When you’ve got Texas A&M University, the biocontainment lab in Galveston, MIT, Argon National Lab, and the Superconductivity Institute at the University of Houston all standing up and saying this technology works and it will kill this virus, that you can hang your hat on,” said Perry.

Developer’s Novel Virus-killing Air Filter Ups Standard for Indoor Air Quality

Real-estate mogul Monzer Hourani wins 2021 ENR Award of Excellence for setting a presto tempo to develop technology that mitigates transmission of COVID-19 in buildings. By Scott Blair/ENR

Last April 13, as an ambulance sped him to the hospital, Monzer Hourani overheard the emergency medical technicians say they didn’t think he was going to make it. Immediately, the 77-year-old medical-building developer started praying: “God, give me time to finish this.”

Hourani had just begun his war against COVID-19, and he needed more time to develop his weapon—an air filter technology that annihilates coronavirus and other airborne germs.

“There is so much death, suffering and isolation. I want to kill the virus indoors and make it safer for people to be together again,” says Hourani, chairman and CEO of Medistar Corp., which he formed in 1983. Vaccines are important but “they won’t help against the next pandemic,” he adds.

Hourani’s Brainchild

Called the Biodefense Indoor Air Protection System and launched last August, Hourani’s brainchild is a proprietary souped-up HEPA filter. Unlike ordinary HEPA filters that trap but do not kill airborne pathogens, the Hourani filter, with its layers of hyper-heated nickel foam mesh, traps and zaps a whopping 99.999% of the coronavirus, with only trace increases in ambient air temperature.

When Hourani collapsed last April, he was in a work frenzy designing the filter. And, like a conductor auditioning an orchestra, he was assembling the filter’s team under his newest business venture, Integrated Viral Protection, which he chairs.


Hourani financed IVP with “millions of dollars” of his own personal fortune. Though a for-profit company, it has a noble purpose: to respond to the COVID-19 global pandemic by fostering research, development and deployment of technologies that offer solutions to mitigate the transmission of biological threats in indoor environments. “My philosophy of life is to help humanity,” says Hourani.

He almost missed his chance, last April 13. “We lost vital signs and CPR was started,” recalls Dr. Garrett K. Peel, Hourani’s doctor and protege, who was with him in the ambulance.

The diagnosis was gastrointestinal hemorrhaging, says the 45-year-old Peel, who also is Hourani’s second-in-command in the virus wars. “I am taking a sabbatical from my medical practice to help deliver Monzer’s invention to the world,” says Peel, IVP’s co-founder and managing director, as well as
Medistar’s executive vice president.


A general surgeon, Peel also is qualified to market the IVP filter. He has a master’s degree in health science and public health policy from Johns Hopkins University, and he majored in political communication at George Washington University.

Like a Tiger

Hourani says he now feels “like a tiger.” But he was in intensive care for almost a week, on a ventilator for a day and in and out of Houston Methodist Hospital at the Texas Medical Center over a six-week period.

It took four surgical procedures and multiple blood transfusions to stop the bleeding. “All the time, Monzer was worried about the invention—designing, sketching, even talking about it to U.S. Senators,” says Peel, who camped out at Hourani’s bedside during the ordeal.

IVP’s small but growing army of virus slayers agree that the technology is more than a weapon against COVID-19. The filter raises the overall standard for indoor air quality, they chorus. And it doubles as a hedge against future scourges because it also kills coronavirus variants, other viruses, allergens and bacteria such as legionella. The filter even zaps 99.8% of anthrax spores, according to test results from the Galveston National Laboratory, which ran the unprecedented live-virus tests on the filter’s prototype.

“It is a revolutionary invention” that allows owners of schools, restaurants, airports, stores, hotels, theaters and all other buildings “to take action today.”
—Kenneth Thorpe, Institute For Advanced Policy Solutions

IVP has sold $15 million worth of the product since August. “This is a paradigm shift in how we look at the future of HVAC systems,” says Peel, who participated with Hourani in the filter’s research and development at the Texas Center for Superconductivity of the University of Houston (UH).


For mobilizing and financing a team to quickly develop and deploy his brainchild; for raising the bar for higher-quality indoor air, especially as a hedge against future scourges; and for going above and beyond the call of duty to help free people and the economy from the shackles of COVID-19, the editors of Engineering News-Record have named Monzer Hourani the winner of the 2021 ENR Award of Excellence.


“Without Monzer, there would be no technology,” says Zhifeng Ren, director of the Texas Center for Superconductivity, co-lead researcher and one of Hourani’s filter co-inventors, with UH postdoctoral fellow Luo Yu. The three are listed on the patent application, filed last fall.


Ren, who currently also serves as IVP’s scientific advisor, considers the filter among his most important projects.


“It is a revolutionary invention” that allows owners of schools, restaurants, airports, stores, hotels, theaters and all other buildings “to take action today,” says Kenneth Thorpe, executive director of Emory University’s Institute for Advanced Policy Solutions. “The filter has economic importance and will have an impact on morbidity and mortality,” predicts Thorpe, who came upon IVP last summer while researching air purifiers. Impressed with the filter as different from others, he joined IVP as a consultant, to make the filter’s economic and public health case.


Response to Complex Emergencies

Though a dreamer, Hourani is also a pragmatist. He knows a single invention will not conquer any pandemic. Consequently, this week he is launching—and funding—a nonprofit consortium of scholars, scientists, engineers, construction leaders and policy experts to help “deploy life-saving technology” in response to complex emergencies, such as environmental disasters and pandemics. The mission of the public-private partnership, called the Global Institute for Biodefense and Emerging Solutions, is to clear barriers to innovation for startups, so they can deploy new technologies—from proof of concept to manufacturing—at a much faster pace.


Thorpe and T. Allan McArtor, chairman of Airbus North America and a former Federal Aviation Administrator, co-chair the consortium. “If we assemble the experts, we can figure this out” for generations to come, Hourani says. “We need to be ahead of the next crisis, not on the defensive.”


Though his first profession was structural engineering, Hourani is primarily a developer. Also a classical music devotee, he guest conducts at two orchestras he supports financially.


Described by others as brilliant, talented, generous, devoted and “very intense,” Hourani self-describes as a humble man­—but one with little patience and a bad temper.


For his COVID-19 crusade, Hourani’s impatience is an asset. With the death toll mounting, “we’re still in a race against time,” he says.


Hourani’s rescue mission started early last year when, ahead of most of the pack, he warned that airborne COVID-19 transmission was going to kill hundreds of thousands and shut down society. Too restless to wait for a vaccine, he wanted to take action. But he wasn’t sure how to proceed.


His path forward revealed itself by happenstance on March 27 of last year—not long before his near-death experience. The circumstances bring to mind Alexander Fleming’s 1928 discovery of penicillin. When Fleming returned from vacation he noticed mold—growing on an accidentally contaminated staphylococcus culture dish—had stopped the bacteria’s growth.


Hourani’s “aha” moment was both more mundane and more dramatic. Impatient to eat, he had ordered his housekeeper to make a grilled cheese sandwich—fast. She quickly popped a sandwich into the toaster and left the kitchen. 


Big mistake. Cheese sandwiches and toasters don’t mix, especially untended. The sandwich burned.


Hourani raced to the scene. Watching the billowing smoke rise toward the exhaust vent, he thought, “Why don’t we grill not a cheese sandwich but corona?”


He started sketching, took the toaster to work and never looked back. By March 31, Peel had contacted the Texas Center for Superconductivity for help. Thanks to “team Hourani,” it took only five months to get the air filter designed, laboratory tested, peer reviewed, beta-tested, certified, manufactured and deployed (see sidebar).


The tempo is considered warp speed for new technology.


Childhood Traumas

Hourani’s drive to rescue humanity, combined with his intense desire for peace on Earth, are informed by several childhood traumas related to strife in the Middle East. Part of a prominent Christian family originally from Marjayoun, in the mountains of South Lebanon, Hourani was born on June 22, 1943, to Adib and Adiba, in nearby Palestine, where his grandfather owned land. He has three younger siblings.


He had his first traumatic experience at age five. To escape the 1948 Arab-Israeli War, his family abandoned its holdings in Palestine and fled back to Lebanon, soon after the burning of the church his family attended. “My birth records were destroyed, so I don’t know exactly where I was born,” says Hourani.


He grew up in Tripoli, Lebanon’s second largest city, where his father taught college English and history. For a time, life was not bad. When he was six, he discovered music. “At age eight, I conducted songs with my friends and tried to make them love classical music, but all my efforts were wasted,” he says.


Hourani studied piano, but soon he started playing music in his head, especially on his solo explorations. Curious about trains and nature, he would often wander off without telling his parents. On one occasion, he hopped on a train, fell asleep and woke up at the border. He was rescued by a couple on the train who happened to know his parents.


Less than a decade after the family returned to Lebanon, political tensions—which eventually erupted in the July-to-October Civil War of 1958­—started mounting. Hostility kept growing between the warring sides—Muslims against ruling Christians. The U.S., which supported the Christian President Camille Chamoun, was also involved.


The Houranis were caught in the crossfire. “All our family was for peace, including peace with Israel,” says Hourani.


The hostility caused his second trauma, at age 14. Thanks to a fascination with “America, American Indians and the Wild West,” Hourani would often while away the hours at the U.S. Information Services Library.


On May 8, 1958, Hourani and his favorite librarian, Stefan, heard noises and looked outside. People were running toward the library, throwing rocks. Hourani hid under a table, but Stefan was caught by the mob.


“They stabbed him to death,” Hourani says, who escaped, ran home and didn’t stop screaming for two days.


The May 8-10 riots resulted in 15 deaths and more than 128 wounded. And the insurgents destroyed the library.


That trauma was horrific enough but it paled by comparison to his next one, about six weeks later.


On June 21, a day before his 15th birthday, Hourani and his mother were out helping poor people in a neighborhood known to be unsafe. In a flash, in front of his eyes, his mother was shot and killed.


Classical Music Healed My Wounds

Somehow, Hourani and his family carried on. “Classical music healed my wounds,” he says.


Seven years later, after receiving baccalaureates from the French Institute in both mathematics and physics, Hourani left Lebanon to study at the University of Texas at Austin. By 1969, he had bachelor’s degrees in architectural studies and architectural engineering, with a focus on structures.


After a stint in Detroit at Giffels & Rosetti, he returned to Lebanon. He came back to the U.S. in 1971, and had an assignment with an architect in Phoenix. In 1972, with structural engineer Don Lenert, he formed Lenert Hourani & Associates Structural Engineering. That firm became M. Hourani & Associates Inc. in 1975, when Lenert retired.


Also in 1975, Hourani became a professional engineer. His license remained active until 2019, when he forgot it was up for renewal. It expired without his awareness. Last year, he submitted his renewal application, which is pending.


“With the pandemic, my recent health setbacks, family difficulties in Lebanon and the licensing board’s requirements, the problem took a good part of last year to rectify,” he says.


In the early 1980s, there was another civil war in Lebanon. Hourani sold his engineering business to take care of his family, mostly still living there. In 1983, he founded Medistar, which he owns with the Hourani Family Trust.


“Through health care development, I was able to stay true to my passion for structural engineering,” he says.


The filter is Hourani’s first global crisis intervention. But he has other inventions. In the 1970s, to solve cracking caused by poor soil conditions in Houston’s slabs on grade, Hourani applied post-tensioning—typically reserved for higher-up thin slabs—to grade slabs. He also used PT in retaining walls.


Troubled by the poor performance of windows during hurricane winds, Hourani invented a window brace. Patented in 2002, it is designed to resist winds from Category 4 and 5 hurricanes. The brace is installed temporarily in advance of a storm.


Inspired by the 1989 Exxon Valdez spill in Alaska, he conceived of an oil skimmer. After the April 2010 Deepwater Horizon disaster in the Gulf of Mexico, Hourani spent several weeks on site with British Petroleum officials and the Corps of Engineers, refining the skimmer for use in the cleanup, he says.


More recently, spurred by Hurricane Harvey in 2017, when he had to be rescued by boat from his house on the Buffalo Bayou, he developed a concept called Project Dam. It is intended to relieve flooding along the bayou through the construction of discharge outlets and associated works for the Addicks and Barker reservoirs.


Renaissance Man

“Monzer is a Renaissance man and the 1% inspiration behind many good ideas,” says Joseph Colaco, president of Colaco Engineers, who has recently performed conceptual structural design for Medistar projects.


Hourani’s earlier inventions are trumped by the filter. IVP deployed mobile devices first because heating, ventilating and air-conditioning (HVAC) system retrofits—with perhaps the biggest potential for impact—are not as simple to deploy as a plug-in unit.


The HVAC application, fitted to existing or new commercial or residential buildings, will debut within two months, according to the Hunton Group, which distributes HVAC systems and products and is partnering with IVP. Hunton’s team is working out the logistics for a “cost-effective retrofit,” says R.O. Hunton, chairman, who declines to offer details so Hunton can stay ahead of the competition (see p. 8).


“We are very, very bullish on the filter,” says Hunton, who was not any easy sell. “Protective of our reputation, we did a lot of research before we agreed to represent this product,” he says. “It’s the only one we were able to find that captured the virus and then instantaneously killed it. And it didn’t increase the air-conditioning load because of the way it was designed and the use of nickel foam.”


Portable Unit for Easy Toting

This month, IVP launched a lightweight portable unit designed to fit into a backpack for easy toting. It cleans a 240-sq-ft area. A larger-venue mobile unit for airports and retail malls, described as an air vacuum that roams the space on a customized electric cart, begins beta testing May 1. A face shield and an automobile filter are in the final stages of R&D. Hourani even has plans for a mini-filter that fits into an elevator cab. And he is working on a version that can be retrofitted into a car’s HVAC system.


Hourani decided to deploy to schools first. The Slidell Independent School District (ISD), which draws 345 pre-kindergarten through grade-12 students from four rural counties in northeast Texas, debuted the system last August. Slidell has nine units to help protect students and 52 employees in its two buildings.

“This filter is here for the long term for keeping our students well and it gives staff and parents a sense of safety and security.”
—Taylor Williams, School Superintendent, Slidell ISD

Remote learning last spring, prompted by the pandemic, was a big problem because half the student body did not have the technology needed or good internet or cell phone signals, says Taylor Williams, the school superintendent. Students fell three months behind in their studies, she says.


“In June, the principals and I knew there was no way we were going to be able to make remote learning work after the summer break,” says Williams. But in-person learning was going to be more difficult, especially since it had become clear that transmission was primarily through droplets, she adds.


Then, in July, the region’s state representative, Phil King, called Williams to inquire whether Slidell wanted to be the first school demonstration site for the filter. Not believing her ears, Williams did some research and accepted the offer.


The IVP units, mostly paid for with $12,500 of CARES Act funds, arrived and were plugged in on Aug. 18, the day before school started. Within six weeks, attendance was better than ever, at 98%.


“The COVID numbers around us, in other districts, kept going up, but we never spiked,” Williams says. A side benefit was that there was no strep and no flu this winter. “This filter is here for the long term to keep our kids well, and it gives the staff and our parents a sense of safety and security,” she adds.


Williams has had inquiries from other superintendents. One came last summer from Kelli Moulton, the recently retired superintendent of the Galveston ISD, which serves 7,000 students on 13 campuses.


Galveston has since made a $100,000 investment in 78 classroom-size machines and 45 larger units for gyms, libraries and cafeterias. Again, CARES Act funds helped.


In Galveston, 88% of students are back in school. “I don’t think there is any metric solid enough now to determine the effectiveness” of the units in preventing the spread of COVID-19, especially because people can be exposed elsewhere, says Moulton. “But it’s one way to make people feel more comfortable,” she adds.


Moulton is such a fan of the filter that in February she signed on as a Hunton consultant. As the educational and governmental leader for IVP distribution, she is working through a list of superintendents in the more than 1,200 school districts in Texas. She started with the areas that have the most COVID-19 cases.


IVP units are currently in buildings in 45 states and Dubai, Oman, Saudi Arabia, Qatar, South Korea and Hong Kong, says IVP. The filters are in more than 100 public and private hospitals, including COVID-19 facilities. Two convention centers are outfitted, with a third on its way. Three international hotel chains are installing them.


Number of Installations Growing

The number of installations keeps growing, mostly but not exclusively in Texas: schools, early childhood centers, nursing homes, municipal buildings and gyms. The 250,000-sq-ft Canyon Ranch Spa in Las Vegas now has units. And the number of office buildings with units also is growing.


IVP is in partnership with Asset Living, a student housing provider, and Greystone Senior Living. And it is working with Medical Properties Trust, which provides capital for hospitals, and the Steward Health Care Network.


IVP deployed units to Michigan’s Wayne County Jail. And the U.S. Dept. of Defense has granted IVP $750,000, coming in three installments, to develop the technology for war zones.


In coming weeks, IVP will be presenting to state COVID-19 task forces in California, Michigan, Pennsylvania, New York, New Jersey, Florida, Arizona and Nevada, says Peel.


Hourani is proud of his 10-person IVP team. And he is equally impressed by his 25-person Medistar team.


“In these times, to be able to forge ahead, finance and deliver the largest public-private partnership outside College Station for Texas A&M University is nothing short of a miracle,” he says, referring to a $550-million student housing, biomedical and life-sciences project under construction at the Texas Medical Center.


In downtown Phoenix, Medistar hopes to break ground this year on a $300-million apartment, office, retail and student housing project that encloses 1 million sq ft, located at Central Station. “Monzer’s keen attention to detail is what sets him apart from other developers,” says Christine Mackay, the city’s economic development director. “He challenges everyone to be their best.”


Hourani has close relationships with collaborators. “His performance as a developer is without peer,” says William Harlan, chairman and CEO of Ascend Medical Holdings, which invests in health care properties.


Despite his accomplishments, Hourani—who was vaccinated several months ago and wears a mask in public places that don’t have IVP filters—is under stress on several fronts.


He has long felt responsible for the care of relatives in Lebanon, which remains in deep turmoil. And the pandemic and its economic ramifications for Medistar—financing is tight, projects are on hold—are weighing heavily on his shoulders. “I am spread between all of this,” he says.


Antidote to Stress

Again, his antidote to stress is music. On April 8, he guest conducted at a performance involving the UH Moores School Symphony Orchestra, the Virtuosi of Houston youth orchestra and members of the Houston Symphony and Houston Grand Opera. The concert, which Hourani sponsored, was at the Wortham Theater Center, equipped with IVP filters. Another concert with only the UH orchestra is scheduled for May 1 at the Moores School Opera House, also equipped with the filters.


Hourani supports both the Virtuosi and the UH orchestras. “Monzer is in life for young people,” says Franz Anton Krager, who co-conducts the Virtuosi with Andrzej Grabiec. Both teach at the Moores School, which Hourani also supports.


There are IVP units throughout the school­—in the lobby, in practice rooms and in rehearsal and performance halls, where the Virtuosi also plays. “Monzer brought the winds, who couldn’t play wearing masks, back to the orchestras,” says Krager, who is “blown away” by Hourani’s knowledge of music and his many other achievements.


Hourani only gets to conduct at a few concerts a year. That doesn’t stop him from enjoying his favorite pastime. Because he hears the music in his head and he never uses a score, he can conduct, or rather “air” conduct, at the drop of a hat—anywhere, any time and at any volume.


All Hourani needs is his baton and he is a happy camper, truly absorbed in his treasured sounds of music.

Banquete Independent School District purchases a biodefense air filtration system

By: Corderro McMurry

CORPUS CHRISTI, Texas — Banquete Independent School District has placed a biodefense air filtration system throughout their campuses as an extra layer of defense against COVID-19.

An Integrated Viral Protection air filtration system that is helping businesses and schools reopen safely by installing the IVP biodefense indoor air system.

The indoor air system works by forcing air through a heated filter that captures and kills contaminants including airborne pathogens without significantly changing the air temperature. The school district purchased 27 of them as an extra layer of protection for their students and staff throughout the campuses.

“We felt like we needed to get into the game to protect everybody that was here with something inregards to the air quality that they were going to be breathing and that is the reason we went this direction,” said Max Thompson Banquete ISD Superintendent

With the COVID relief funds and approval from the board, the school spent $35,000 for the 27 units.


The Challenges of Making Indoors Safe

Risks of catching COVID shoot up when virus particles accumulate in buildings, but it’s not clear how best to improve ventilation. By Dyani Lewis

When Lidia Morawska leaves home, she takes with her a slick, shoe-sized device that provides some sobering insights about the restaurants and offices she visits. Outside these buildings, her carbon dioxide monitor reads just above 400 parts per million (p.p.m.). But indoors is a different story. 

Even in a seemingly spacious, high-ceilinged restaurant, the number sometimes shoots up as high as 2,000 p.p.m. — a sign that the room has poor ventilation and could pose a risk for COVID-19 infection. Visual cues can be deceptive, even for Morawska, an aerosol scientist from the Queensland University of Technology in Brisbane, Australia. “The general public has no idea about this,” she says.


The situation is no different inside cafes or kindergartens around much of the world, according to researchers who have wielded similar handheld CO2 meters. And that’s bad news for hopes of defeating the coronavirus SARS-CoV-2. 


For months, health authorities have singled out indoor spaces with poor ventilation as potential infection hotspots. And on 1 March, the World Health Organization (WHO) released a long-awaited road map to better ventilation. The document — which Morawska contributed to — sets out specific targets and measures that businesses and other places can take to improve ventilation and make buildings safer. 


But Philomena Bluyssen, a building engineer at the Delft University of Technology in the Netherlands, says that more needs to be done. “The WHO guidelines,” she says, “are the minimum.” 


Bluyssen and others are critical of governments’ failure to provide clear guidance or money for people to make indoor spaces safer. Some scientists say that has left large swathes of the population — from schoolchildren to office workers, restaurant goers and prisoners — at risk of catching COVID-19. 


Others say that there’s no easy fix, and the precise ventilation or air-purification regimes to make indoor spaces safe are not known. “The complexity is not at a level that you can — with a simple set of advice — resolve it,” says Ehsan Mousavi, a construction engineer at Clemson University in South Carolina, who studies indoor air quality and ventilation in hospitals. 


Still, many experts say that enough is known for authorities to provide a clear message about how important good ventilation is for safety indoors, especially in spaces that are continuously occupied, or where masks are removed when eating.

Slow recognition

On 28 March 2020, two months after the WHO had declared COVID-19 a global health emergency, the agency broadcast a public-health message on Twitter and Facebook. “FACT: #COVID19 is NOT airborne,” it said, labelling claims to the contrary as misinformation. But evidence quickly established that the virus is transmitted by air, and researchers roundly criticized the agency.

The WHO updated its advice on SARS-CoV-2 transmission three months later, acknowledging the possibility that airborne transmission might occur in some community settings. Airborne transmission in “crowded and inadequately ventilated spaces over a prolonged period of time with infected persons cannot be ruled out”, the updated advice says. 

Yuguo Li, a building environment engineer at the University of Hong Kong, says that he is disappointed it took the WHO and other health authorities so long. “We would have saved a lot of people” if airborne transmission was recognized earlier, he says. 

A WHO spokesperson says the agency has mentioned the importance of ventilation since early in the pandemic. 

Others say that the WHO’s position still doesn’t go far enough. “Airborne transmission is dominant,” says environmental epidemiologist Joseph Allen at Harvard University’s T. H. Chan School of Public Health in Boston, Massachusetts. That’s why building controls such as ventilation and air filtration make sense, he says. 

The WHO and other health authorities have failed to clearly prioritise measures to improve indoor air quality to reduce the chance of catching COVID-19, says Jose-Luis Jimenez, an atmospheric chemist at the University of Colorado at Boulder. “They don’t emphasize how important it is,” he says. What the WHO needs to say is “fact, it goes through the air,” says Jimenez, “we breathe it in.” 

A stark message from the WHO would ensure that national health authorities take notice, says Jimenez. Australia, the Netherlands and some other nations still do not acknowledge in their public statements that airborne transmission has a significant role in spreading the SARS-CoV-2 virus.

“If we took half the effort that’s being given to disinfection, and we put it on ventilation, that will be huge.”

By the start of this year, concerns over ventilation had reached boiling point. Hundreds of health-care workers, scientists, engineers and occupational health-and-safety experts signed open letters calling on government officials in Canada, the United States, Australia, Colombia and the United Kingdom to address, among other things, poor indoor air quality. These concerted campaigns all urged local or national governments to take steps to reduce airborne transmission of SARS-CoV-2.

One of the problems is that governments and businesses are still spending millions of dollars on surface disinfection, says Jimenez, despite evidence that it is rare for SARS-CoV-2 to pass from one person to another through contaminated surfaces. By contrast, few countries have invested in measures to improve indoor air quality. 

“If we took half the effort that’s being given to disinfection, and we put it on ventilation, that will be huge,” Jimenez says. In October, Germany set aside €500 million (US$593 million) to improve ventilation in public buildings, including schools, museums and public offices. 

Businesses in Germany and South Korea can also apply for government funding to purchase mobile air purifiers that remove virus-laden aerosols. In the United States, by contrast, federal funding to improve indoor air quality was limited to health-care providers such as hospitals, until the American Rescue Plan Act — which also provides funding for schools — became law on 11 March.


Indoor Threat

What makes indoor spaces so dangerous is that exhaled virus can accumulate and infect people who do not have direct contact with an infected person. A prime example happened a year ago during a St Patrick’s Day party at a bar in Ho Chi Minh City, in Vietnam. Twelve people became infected at the party, but only four had close contact with the infected person . More recent outbreaks at gyms in Chicago, Illinois, and Hawaii have also occurred despite physical distancing of attendees and capacity limits on fitness classes. 

Ever since the WHO acknowledged last year that airborne transmission could happen, public-health agencies have emphasized the risks in crowded and poorly ventilated spaces. But the terminology is deceptive, says Morawska. “You imagine a busy bar,” she says. “In the reality, any place can become crowded and poorly ventilated. And people don’t realize this.” 

Her own modestly sized office at the Queensland University of Technology quickly becomes poorly ventilated if someone visits and the door is closed, she says. And spacious, uncrowded restaurants can appear to be well ventilated when they are not. 

It’s one of the reasons that Jimenez and others advocate the use of inexpensive CO2 monitors as a rough measure of whether ventilation is adequate or not. As virus-carrying aerosols are exhaled, so too is CO2. And when ventilation is poor, CO2 accumulates along with the virus, says Jimenez. In an unreviewed analysis5 , Jimenez and his co-author Zhe Peng found that SARS-CoV-2 infection risk rises along with CO2 concentrations indoors. 

Taiwan, Norway and Portugal have laws that limit indoor CO2 to 1,000 p.p.m. Studies in California6 and Madrid7 show that CO2 levels in school classrooms frequently exceed this level. High levels have been linked to poorer mental concentration and more sick days. 

Setting clear CO2 limits would help to ensure that ventilation is adequate to reduce infection risk, says Jimenez. But his work suggests that in general 700 p.p.m. would be a better limit, and lower limits should apply to gyms and other venues where people expel greater volumes of air. 

Not everyone agrees that CO2 monitors are the solution. “There is no correlation between CO2 and virus,” says Christian Kähler, a physicist who studies aerosol production and dynamics at the University of the Federal Armed Forces in Munich, Germany. This can give people a false sense of security when CO2 levels are low, he says. 

Jimenez argues it could provide a quick indication of whether ventilation is adequate. In August 2020, the Federation of European Heating, Ventilation and Air Conditioning Associations (REHVA) agreed, recommending installing CO2 monitors in buildings where ventilation might be inadequate. 

And late last year, teachers in Montreal, Canada, covertly measured CO2 levels in classrooms and took their findings to the media. The Quebec government is now publishing CO2 levels from public schools online, with the aim of having all levels below 1,000 p.p.m. But so far, this type of public reporting is the exception.


No Set Standards

Part of the difficulty in setting ventilation targets is that it’s unclear how much ventilation is needed to reduce infection rates to an acceptable level. Experiments that directly measure how infection risks change with different ventilation rates would be unethical because it would put people in danger, says Mousavi. 

The precise infectious dose for SARS-CoV-2 is also unknown. But researchers can infer how much exhaled virus is needed to cause infection by analysing disease outbreaks. For example, Jimenez and colleagues used details from an infamous choir rehearsal in Skagit Valley in Washington — where one person probably infected 52 of the 60 other attendees — to estimate the amount of infectious virus exhaled.


Jimenez used this approach to launch an online tool (which has not been peer reviewed) in June 2020 to help people assess the risk of infection in different indoor spaces, with or without masks. The tool calculates risk based on room size, the number of people present and what they are doing; viruses are exhaled at different rates depending on whether people are singing, running on a treadmill or sitting quietly. 


The WHO recommends a minimum ventilation rate of 6–12 air changes — in which the entire volume of air in the room is replaced — per hour to prevent airborne transmission of pathogens in health-care facilities, but a lower rate of air changes for other venues. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) establishes minimum standards for indoor air quality. Recommended targets are as low as 0.35 air changes per hour for homes, 2–3 for offices, 5–6 for schools and 6–12 for hospitals. 


But even those minimum standards are rarely met, says Liangzhu (Leon) Wang, a mechanical engineer at Concordia University in Montreal. And although experts say that more ventilation is needed to reduce infection risk, they disagree over how much. For schools, Allen recommends 4–6 air changes per hour, which can come from a combination of outdoor air ventilation, filtration or supplemental air cleaning. Kähler meanwhile, recommends at least 6 air changes per hour. 


Wang and his colleagues have tried to estimate what level of ventilation is required to reduce infection risk at schools. They measured the ventilation rate in classrooms at 3 schools in Montreal and found that a classroom of 20 students and one teacher with open windows exchanged less than half of its air per hour; a similar room with mechanical ventilation had two air changes per hour. Even that wouldn’t be enough to reduce the reproduction number to less than 1 — the level at which a pandemic begins to shrink. This value would mean that one infected student passes the virus to less than one other person in the room. Wang’s analysis, which is yet to be peer reviewed, suggests that between 3 and 8 air changes per hour would be required to get the reproduction number below 1 in that setting. 


Standard ventilation rates are inadequate, says Wang. In another preprint, he and his colleagues estimate that doubling the amount of outdoor air reduces the chance of infection by up to 35% in densely packed venues such as restaurants. But that same change has a much smaller effect — reducing risk by as little as 0.1% — in larger venues with fewer people, such as warehouses. Their analysis also shows that wearing a mask indoors is even more effective than changing the air: masks decrease infection risk by more than 60%, because they cut the virus off at its source, says Wang.


Clearing the air

Opening windows is the easiest method that health authorities suggest to improve ventilation. Although it is better than doing nothing, an open window rarely exchanges enough air between the indoor and outdoor environment, especially if there is no cross-breeze, says Kähler. 

“In the reality, any place can become crowded and poorly ventilated. And people don’t realize this."

Opening windows for just a few minutes — between classes, say — would leave the majority of virus untouched, according to air-exchange measurements Kähler and his colleagues took in a university lecture room11. In a preprint study, Kähler found that two windows that allow a cross-breeze would need to be open two-thirds of the time to equal the performance of the room’s heating, ventilation and air-conditioning (HVAC) system. And if the weather outside is too hot or cold, people simply won’t follow that advice. “It protects you sometimes, but not always,” he says. 


A better method is to mechanically ventilate a space. This draws in virus-free outdoor air and removes contaminated indoor air, thereby diluting any virus present. In April 2020, ASHRAE and REHVA recommended setting HVAC controls to draw in as much outdoor air as possible and to filter recirculated air. 


But Kähler says that few buildings, especially in milder climates such as in Germany, have systems powerful enough to use 100% outside air. Most office spaces and classrooms around the world are supplied with just 20% outside air, with the remainder recirculated to save on energy consumption for heating and cooling. 


The environmental cost of increased ventilation should give people pause, says Li. In many cases, beefing up ventilation systems now will mean removing them once the pandemic threat subsides. A better solution, he says, is to limit numbers and curb risky behaviours. “Don’t shout, don’t sing and don’t run,” he advises. Another drawback of cranking up building ventilation is that rooms can become draughty and noisy, says Bluyssen, “because the system wasn’t designed for that”. 


Mobile air purifiers that filter out viruses and other airborne contaminants could be readily deployed as part of the solution, says Kähler, and would be more energy efficient than using extra heating or cooling on outside air. Filters in HVAC systems could also clean air that is recirculated. 


Bluyssen and her colleagues tested air purifiers fitted with high-efficiency particulate air filters in a controlled environment. In some scenarios, the air purifiers outperformed the ventilation system for removing aerosols simulated by air-filled soap bubbles. But even on the lowest setting, the air purifiers exceeded the acceptable level of noise and draught recommended by European and Dutch standards. 


Innovation is required to address the shortfalls of current systems, says Bluyssen: “We really need to look for simple, affordable solutions.” One idea she’s looking into is personalized ventilation — a seat fitted with a system that sucks away exhaled air and returns it filtered and cleaned, for instance. “There are all kinds of possibilities,” she says. 


But Mousavi says that the biggest issue is that not enough is known about the systems that are already in use. “We need to know more about these technologies, how they perform,” he says, so that recommendations — from ASHRAE, or the WHO, or another agency — are based on clear science. “It’s time for us to build that foundation,” he adds. 


As vaccines are rolled out and the risk of infection drops, the window of opportunity to fix poor indoor air quality is closing, says Morawska. “This hasn’t passed yet,” she says. But next year, “it may be too late”. 


Researchers say that a greater focus on ventilation will yield benefits during the next pandemic — and even when there are no major disease outbreaks. Indoor air quality “has been very bad for a long time”, says Bluyssen. “This gives us the opportunity to improve not only the air quality for pandemic situations, but also the whole indoor environmental quality for the future.

Helping Reopen Texas: New Biodefense Technology Plays Pivotal Role in Providing Cleaner, Viral-Free Indoor Air Across the State

Integrated Viral Protection (IVP) air filtration technology that catches and kills actual Sars-CoV-2 (virus causing COVID-19) instantaneously; installing in facilities throughout Texas this week

HOUSTON, March 17, 2021 ( – On the heels of Governor Abbott’s call to fully reopen Texas, Houston based, Integrated Viral Protection (IVP) is helping businesses do so safely, with the installation of the IVP Biodefense Indoor Air SystemTM – the only existing air filter system which can instantaneously catch and kill airborne COVID-19 (99.999%), other RNA viruses, and anthrax spores (99.98%) in a single pass. IVP’s core technology is a specialized heated filtration system, invented by Monzer Hourani, which meets ASHRAE standards and has been granted emergency use authorization by the FDA during the COVID-19 pandemic.


IVP is playing an integral role in reopening businesses and keeping children in schools across Texas with deployments in over one hundred Texas school campuses to include Galveston ISD, Slidell ISD, Comal ISD, Banquete ISD and Houston ISD. The medical devices have been installed at schools across the US, including hot zones in Florida.


Current installations include the Intercontinental Houston Medical Center, Baytown City Government, Fulton City Government, University of Houston, Texas A&M University, T-Mobile tower, St. Joseph’s Medical Center a Steward Health Care Facility, HotWorx gyms, the San Antonio Riverwalk, Texas Department of Emergency Management and Department of Public Safety, Rosewood Hotels, Hilton Hotels and more. The Texas Restaurant Association has endorsed IVP for use in Texas restaurants to get hospitality businesses back to work safely as well. IVP is installed in health care settings across the US to include over 100 hospitals and healthcare facilities, including COVID-19 specialty hospitals, neuro-psych facilities, rehabilitation hospitals and tertiary centers including University Hospital System. The device was recently installed to incarceration facilities in Michigan.


IVP has deployed units to help keep Texans safe while returning to work and schools:

  • George R Brown Convention Center, Houston

Wayne County 1st Jail System In US To Install Groundbreaking Device That Kills Airborne Viruses/COVID-19

CBS DETROIT – At the William Dickerson Correctional Facility there’s some ground-breaking technology taking place that targets COVID-19 and other airborne illnesses. It’s called the Integrated Viral Protection, or IVP and Wayne County Sheriff Raphael Washington says it’s groundbreaking technology in the fight against COVID-19


“We’re going to attack COVID where it lurks, in the air.”


Sheriff Washington says the IVP will make this happen. The machine works as an air disinfecting system and Wayne County is the Country’s first Jail to receive one.


Dr. Garett Peel MD, IVP founding partner says, the system is placed in over 100 schools, hospitals and entertainment venues throughout the County, and is proven to kill airborne illnesses, including COVID-19.


“So it’s important that we are pumping clean fresh air to focus on the re-circulation and kill whatever is in the air instantaneously and that’s what this medical device does, we are FDA approved for sell during the COVID-19 pandemic.”


Dr. Peel says it’s important to have this system is largely populated environments such as prisons, where the virus is easily spread. He says in its current locations they have proven success.


“Thankfully seen a decrease in infection rate where we have deployed these units.” Said Dr. Peel during a press conference at the Dickerson Correctional Facility on Thursday.


The Wayne County Sheriff’s office has the units in 5 locations, including the 2 downtown jails and the Dickerson facility in Hamtramck. Having loss several staff members to COVID-19 including the County’s Sheriff Benny Napoleon, Sheriff Washington says doing all they can to mitigate the virus is extremely important to the office.


“These losses have focused us to do all we can to prevent COVID from threatening everyone who comes in contact with this agency.”


Washington says they are continuing to take other safety precautions including masks wear, inmate and staff COVID testing. He says there are currently 350 staff members that have received vaccinations.


“This does not replace CDC guidelines we still want to make sure that this is a level of enhancement a level of security.” Says Dr. Peel


He hopes to have the units in other heavily populated facilities throughout the state of Michigan.


3 Wayne County jails become first in US to start installing COVID-19 air disinfectors

DETROIT FREE PRESS – Three Wayne County jails are the first detention facilities in the U.S. to implement groundbreaking heated filtration technology units to tackle the spread of COVID-19.


Thus far, 12 Integrated Viral Protection (IVP) units have been installed at five Wayne County buildings, three jails and two administrative. Through powerful circulation, the IVP units catch and kill airborne viruses — including tuberculosis, influenza as well as the novel coronavirus — while disinfecting the air. 


The decision to integrate the system was a personal one for Sheriff Raphael Washington, he said during the announcement of the new system Thursday, as it began under the leadership of the late Sheriff Benny Napoleon. Napoleon died of the virus on Dec. 17 after experiencing complications that required hospitalization.


“This is personal for us as it relates to losing people within our facility, but we want to make this technology great for everyone coming into our facility,” Washington said. “These losses have allowed us to focus to do all we can to prevent COVID from threatening everyone who comes in contact with this agency.”


The Wayne County Sheriff’s Office has been hit hard by the pandemic and has lost multiple personnel members, including one officer and one commander. According to the sheriff’s office, 270 members have tested positive throughout the pandemic. 


The IVP system is another layer of caution in the agency’s efforts to slow the spread of the novel coronavirus. Other efforts include biweekly testing of personnel, frequent sanitization, and collaborating with Wayne County Prosecutor Kym Worthy to reduce the inmate population when possible.


Working with the county executive’s office, the agency has secured $300,000 in funding for this project but it will cost the county $240,000 thanks to donations, Washington said. A single venue mobile unit, which has a circulation of up to 2,000 cubic feet per minute, retails for $15,000. 

The sheriff’s office so far has employed 12 venue mobile units and 10 room mobile units, which retail for less than $5,000, in five facilities. It is fully operational at the county’s Division I, II and III jails, the sheriff’s headquarters on Woodward Avenue in Detroit, and its road patrol office on Henry Ruff Road in Westland. Authorities did not have an estimate for when all facilities will have the IVP system implemented. 


“We know that the virus can be suspended into the air, it can live amongst us for hours and it can even travel in HVAC ducts,” Dr. Garrett Peel, co-founder of IVP. “So it’s important that we are pumping clean fresh air to focus on the re-circulation and kill that whatever is in the air. And that’s what this medical device does.”

How it works

IVP devices are deployed into high-risk areas based on the Wells-Riley model that evaluated the infection risk among populations. Through powerful circulation, the disinfector essentially interrupts transmission by diluting and cleansing the air.


“This is not an air purifier, it’s an air disinfector,” Peel said, “and we’ve proven that by being able to kill spores.”


Spores are considered the gold standard by experts as the particles can survive harsh conditions and don’t require many nutrients. The devices can catch and kill spores at almost the same rate they can instantly kill SARS-CoV-2, the virus that causes coronavirus.


The heated filter inside the devices kills 99% of SARS-CoV-2 instantly, according to IVP’s research. The devices have been implemented in schools, office buildings, restaurants, and hotels across 36 states thus far. The Wayne County jails and administrative buildings are the first in Michigan.


As the size of coronavirus variant B.1.1.7 virus is the same as the original SARS-CoV-2, the devices are able to similarly attack the variant. 


“It doesn’t matter if it’s a variant or not, it’s the size that matters,” Peel said.


Detention centers in Michigan have proven to be particularly vulnerable to the pandemic, with high infection rates as many are in close proximity. More than half of the state’s B.1.1.7 cases have been reported at an Ionia prison.


Vaccination efforts have begun for personnel with the Wayne County Sheriff’s Office and 350 employees have received either one or both doses of vaccinations.


PAM expands indoor biodefense system to kill COVID-19

FOX 56 – Today, one medical facility announced a deployment of a new indoor biodefense system to help eliminate the airborne transmission of COVID-19.


Post Acute Medical is the first in our market to install the cutting edge IVP system.


The system has a 99% kill rate and kills other viruses as well.


“We do accept a lot of patients here with our focus being on respiratory and wound care we see a lot of COVID recovering patients so it’s really important keeping everybody safe,” said David Long, CEO of PAM Specialty Hospital of Wilkes-Barre. 


Long says Post Acute Medical invested millions of dollars to provide the IVP system, in its locations throughout the country.
