NASA-Based ActivePure Technology® Rapidly Eliminates 99.9% of Airborne SARS-CoV-2 Virus in FDA-Compliant Military Lab Tests

DALLASDec. 14, 2020 /PRNewswire/ — ActivePure Technologies, LLC, announced that its air purifying technology inactivated over 99.9% of highly concentrated airborne SARS-CoV-2 virus in an enclosed setting in just 3 minutes, below detectable levels. Testing of the ActivePure Technology® was conducted by one of the world’s top biosafety testing facilities, the University of Texas Medical Branch (UTMB), which primarily tests for the U.S. military and the Centers for Disease Control (CDC). 

“These results demonstrate the effectiveness of the technology in a laboratory setting,” said Dr. William S. Lawrence, PhD, director of the Aerobiology Services Division at UTMB’s Galveston National Laboratory.

ActivePure Technologies foresees widespread use of the technology to reduce the amount of SARS-CoV-2 virus present in the air and on hard surfaces in commercial, residential, and medical settings. ActivePure Technology has been on the retail market as an air purifier for more than 10 years. It is installed as part of HVAC systems or as the core technology inside the company’s portable air purification units. ActivePure Technologies currently sells about 500,000 ActivePure units annually across all brands and product lines but is seeing an enormous increase in demand from its distributors due to the pandemic. 

“ActivePure Technology enables us to go on the offense against airborne coronavirus with real-time elimination of viral particles so we can reclaim the spaces – the gyms, restaurants, diners, theaters, beauty salons and barber shops – that are near and dear to our hearts,” said Joe Urso, Chairman and CEO of ActivePure Technologies, LLC. “Unlike conventional, passive, filtration-based air purifiers, ActivePure works immediately and does not require capture or exposure time. It rapidly and continuously fills a room with virus-neutralizing particles that instantly break viruses down to their component parts, rendering them harmless.”

“ActivePure surrounds a person with protective virus-inactivating air,” Urso added, “which is especially important in a medical setting.  I think of it as a form of Personal Protective Equipment (PPE).”

The Cleveland Clinic is conducting a 2-year study with ActivePure units in its operating rooms to see if the technology can reduce surgical site infections. Daniel Sessler, M.D., chair of outcomes research, said, “The Cleveland Clinic continuously adapts practices to ensure we are providing the safest care for our patients.”

“In this deadly pandemic,” Urso added, “people must have air they can trust.”

The UTMB research was conducted in late November 2020 in a Bio Safety Level (BSL)-3 and -4 laboratory, which studies the world’s most deadly pathogens.Currently, nearly all BSL-4 analysis is dedicated to Centers for Disease Control and Prevention (CDC) and military testing. According to the CDC, BSL-4 facilities “are used to study agents that pose a high risk of life-threatening disease.”2

The tests were done in triplicate, according to FDA guidelines and protocols. Live SARS-Cov-2 virus was sprayed into a test chamber at extremely high concentrations (7+ logs, or over 10 million particles per milliliter). 

Within 3 minutes, ActivePure Technology-based Aerus® Pure & Clean and Vollara® Air & Surface Pro units, calibrated to their lowest setting of only 29 cubic feet per minute of air movement, reduced the concentration of the virus to no more than 1.6 logs, a reduction of 99.96%. The lab was able only to measure down to 1.6 logs, so the actual results may have resulted in a 99.99% or greater reduction. 3 The units only used the ActivePure Technology; all other purification technologies in the units were disabled or removed. 

Andy Eide, Vice President of Engineering of ActivePure® stated, “We believe the best defense is a good offense. Going out on the attack and proactively neutralizing SARS-CoV-2 viruses is a highly effective way to minimize the amount of virus that reaches your mask or lands on surfaces you may touch.” He added, “We manufacture nearly 100 different products with ActivePure, addressing concerns in every imaginable environment from homes to offices, hotel rooms, elevators, and even cars.” 

A full report by the lab is expected before the holidays, said Urso.

He added, “The November research found that ActivePure technology produces enormous reductions in three minutes, but shorter durations were not tested. We will now be testing efficacy in just 30, 60 and 120 seconds to see how quickly we can achieve similar or better results. And we will be working with the BSL-3 and 4 labs to test other highly contagious pathogens in the future.”

About ActivePure Technologies, LLC

In 2017, ActivePure Technologies LLC, formerly known as Aerus Holdings LLC, was recognized by the Space Foundation as the only surface and air-purification technology to effectively adapt and market technology originally developed for NASA to improve the quality of life for all humanity, when it was inducted into the Space Technology Hall of Fame at a reception sponsored by SpaceX.4

ActivePure is a patented scientific process that dispatches super-charged, sub-microscopic particles at tremendous speed. These particles are created by reactions between ambient water and oxygen molecules, a patented matrix coating, and a specific wavelength of UVC light. The particles collide with viruses, bacteria, and air pollutants and immediately turn them into harmless elements.

The technology has been used for several years by HVAC installers and as portable units because of its proven pathogen-killing power. Over one million ActivePure systems are currently in use to help safeguard front-line workers in hospitals such as the Cleveland Clinic and in government buildings, including the Texas State Capitol, homes, restaurants, offices, and other public spaces.

The FDA in June cleared ActivePure technology, deployed in an Aerus Medical Guardian unit, as a Class II Medical Device for use in occupied rooms to inactivate six different pathogens, including an RNA virus similar to SARS-CoV-2.5 Previous research found that ActivePure inactivates the COVID-19 virus on surfaces.6

Other publicized systems, such as HEPA, UV light, and MERV-13 are passive, slow, and may trap pathogens, but fail to destroy them. Many others are so dangerous that people and pets cannot be in the room when they are operating.

Air purifier company seeks emergency FDA approval for device that rids indoor air of virus


As the country races to approve and roll out a coronavirus vaccine, one company is seeking federal approval to attack the ongoing coronavirus crisis from a different angle.

Last week, Dallas-based ActivePure filed an application with the Food and Drug Administration seeking approval to use its range of plug-in air purifiers against SARS-CoV-2, the virus that causes covid-19. The devices are used in homes throughout the United States, utilizing technology shown in studies to kill airborne viruses within enclosed spaces.

Over the summer, the company’s Aerus Medical Guardian was designated a medical device by the FDA for use in health-care settings. At the time, it was shown to kill 99.98 percent of the live virus on surfaces within seven hours. Now, after further testing, the company says more of its products are effective against the virus. But this time it’s tackling the air.

Recent lab tests revealed ActivePure’s patented technology can kill airborne virus particles in three minutes, the company says. When turned on, its Aerus Pure and Clean and Vollara Air and Surface Pro devices work continuously to reduce pathogens indoors, even when people are present in the room.

“We are seeking the (emergency use authorization) for use in all indoor environments so that these areas will be safer for people all over the world in this time of pandemic and beyond,” said Joe Urso, CEO and chairman of ActivePure.

Hundreds of thousands of ActivePure filtration devices are installed throughout the country, the company says. Its technology is available in free-standing units as well as HVAC systems within hospitals, government buildings, restaurants, office buildings and homes. Prices start at $199 and can go as high as $1,499.

It offers its line of products through various HVAC contractors, Aerus franchisees and Vollara distributors. The company says it will sell directly to consumers “soon.”

While many home-based air purifiers rely on passive HEPA filters or ultraviolet light to kill contaminants, ActivePure uses active, NASA-inspired technology to disinfect the air.

Standard air purifiers use a fan and filter system that sucks in unclean air, captures contaminants and pushes clean air back into the room. In the filtration company’s system, a fan brings in free oxygen and water molecules and then converts them into special molecules as they pass through an internal UV light.

Those ionized particles are then sent back out into a room to find and destroy microorganisms.

“Going out on the attack and proactively neutralizing covid-19 viruses is a highly effective way to minimize the amount of virus that reaches your mask or lands on surfaces you may touch,” said Andy Eide, vice president of engineering at ActivePure in a statement.

The disinfecting method has been shown to work against other RNA viruses, DNA viruses, bacteria, mold and fungi, the company says.

NASA developed similar technology referred to as an ethylene “scrubber” in the mid-1990s to help with growing plants. The device would draw in ethylene, a gas emitted by plants that speeds up decay, and convert it into water and carbon dioxide, which help plants grow.

In 2017, the space agency acknowledged the filtration company’s efforts to introduce the technology to people’s homes.

ActivePure used CDC-approved labs that tested its products against the novel strain of coronavirus.

Researchers found ActivePure’s air cleaners could reduce the virus’s concentration in the air by more than 99 percent, according to the company. During testing, the air purifiers were turned to their lowest setting of 29-cubic-feet per minute of air movement.

ActivePure, which is owned by the 96-year-old company Aerus Holdings, isn’t the only air purification firm seeking to combat the ongoing coronavirus outbreak. In September, Hong Kong-based Aurabeat said it received FDA permission to market its device as a medical-grade air purifier under the agency’s modified enforcement policy amid the public health crisis.

More may be on the way. Study trials found the PYURE Company’s air purifier reduced airborne SARS-CoV-2 below the limit of detection in 80 minutes.

The air-cleaning technology may serve as one way to reduce exposure to the virus, which health experts say is spread primarily via respiratory droplets. However, it’s far from a cure or vaccine.

The Environmental Protection Agency warns that disinfecting the air alone is not enough to protect people from the coronavirus. “When used along with other best practices recommended by CDC and others, filtration can be part of a plan to protect people indoors,” the EPA says.



The Aerus Medical Guardian with ActivePure Technology works safely 24 hours a day to protect the rooms where it is installed, even when occupied by large numbers of people.

Aerus has announced that it received Class II Medical Device clearance from the U.S. Food and Drug Administration (FDA) for the Aerus Medical Guardian with ActivePure Technology, the first active air purifier for healthcare. 

The Aerus Medical Guardian is a free-standing, portable unit intended for use in professional healthcare environments. It is a 24/7 airborne contaminant reduction solution. The Aerus Medical Guardian with ActivePure Technology works safely 24 hours a day to protect the rooms where it is installed, even when occupied by large numbers of people.

The product cleared by the FDA is intended for medical purposes and is used to reduce Staphylococcus epidermidis and Erwinia herbicola bacteria, MS2 and Phi-X174 viruses, Aspergillus niger fungal spores, and Bacillus globigii bacterial spores from the air in a temperature-controlled professional healthcare environment of 70 to 71 degrees Fahrenheit, 40%-45% RH.

According to the company, the unit is the only FDA-cleared, real-time, active air-purification unit that quickly and powerfully eliminates airborne contaminants. It also disinfects safely without chemicals and without the need to capture the particles.


The Aerus Medical Guardian with ActivePure Technology has an internal fan that draws in air from the room where the unit is located. Air moves into the unit, where negative ions, created from ion brushes, charge incoming contaminants so that the oppositely charged carbon-coated HEPA filter media can be more easily entrained from the passing air. As air exits the filter, it passes through the ActivePure Cell, which contains two ultraviolet bulbs and a proprietary metal-based photocatalyst. This catalyst, when exposed to the energy from the UV bulbs, creates hydroxyl radicals and super ions, which enter ambient air to oxidize, mineralize and convert organic compounds into nonorganic forms. The released particles, known as ActivePure Molecules, fill the entire air space of the room, rapidly seeking and destroying microscopic pathogens, including RNA viruses, DNA viruses, bacteria, mold and fungi, whereas passive technology, also known as capture, air purifiers require pathogens to pass through the device. 

Air purification systems with ActivePure Technology are currently also used in international health systems, including in United Kingdom, Brazil, Canada, Italy, Poland, Portugal, Spain and Thailand.

NASA-designed air purifier technology helps you breathe easier

 With harsh winters and humid summers, Canadians spend approximately 90 per cent of their time indoors, according to statistics.

“A lot of people don’t realize this, but the air inside your home or office could be up to 500 per cent more polluted than it is outdoors depending on where you live, if your residence or office building is new or old and if you smoke or not, among many other factors,” said Roberto Brunetti, the owner of multiple Aerus franchises in the city.

“And the air is worse when all the windows and doors are closed during the colder months, because you have less circulation.”

With fall fast approaching and the global pandemic continuing to be a major health concern, Brunetti has noticed a marked increase in the demand for the brand’s air purifiers that contain a unique, dual filtration system with both HEPA and ActivePure technology.

In a 300-person survey conducted by Aerus, 77 per cent of people said they would prefer to visit a place with ActivePure technology than one without.

“Businesses with employees returning to the office have been concerned about the air quality, and there has been significant demand for Aerus air purifiers to be installed in private medical and dental offices, accounting firms, and private schools,” said Brunetti. “Many residential homes have also followed suit.”

A local, family-run business with its headquarters on Victoria Avenue in Westmount, Aerus has been in Brunetti’s family since 1982. Aerus was originally established under the well-known moniker Electrolux, which has been in existence since 1924.

Aerus has been honoured at the Smithsonian and is one of few technology companies that has been inducted into the International Space Hall of Fame.

“ActivePure technology was originally developed by NASA to solve the problem of built-up ethylene gas produced by plants in the enclosed environment of a spacecraft,” Brunetti explained.

“What the ActivePure cell does is it takes the hydrogen and the oxygen that are in the air and passes through a UVC light that sits in a honeycomb matrix. Once the hydrogen and oxygen hit the matrix, it oxides the particles and creates hydroxyls. The fan then blows out the hydroxyls, which is what reduces RNA and DNA viruses, both airborne and surface.”

As for the HEPA filter, it works to eliminate all of the other indoor air pollutants, like smoke, dust, pet dander, mould, mildew, ragweed and pollen. “Our HEPA filter purifies down to 0.1 microns; a strand of human hair measures 50 microns,” Brunetti said.

“You can actually feel the difference, the air is lighter and crisper. The only thing I can compare it to is when there’s a big thunderstorm and you go outside right afterwards and the air feels really fresh. It’s like that inside the house all day.”

Air filtration unit features technology developed for the International Space Station

Designed to provide indoor spaces with clean air and surfaces, the Beyond Guardian Air from PureAir Living uses technology originally designed by NASA researchers for use on the International Space Station.

The unit’s ActivePure Technology works in conjunction with a filter that surpasses HEPA quality standards, ion generation, and photocatalytic oxidation technology to reportedly kill or neutralize bacteria, viruses, mold, and fungi in the air and on surfaces as well as capturing 99.97% of particles as small as 0.1 micron. The portable unit works quietly and operates continuously to provide more than 4 air changes per hour in 350 square foot sized spaces and 1 air change per hour in 2,000 square foot spaces.

The Beyond Guardian Air system is designed to help keep indoor air clean and safe thanks to technology originally developed by NASA researchers.
