The outbreak and rapid spread of SARS-CoV-2 has had a dramatic impact worldwide as the virus is highly contagious and spreads by air, contaminated surfaces and personal contact.  Social distancing and masking are primary strategies being used to control the spread of SARS-CoV-2 transmission and infection, but this approach is not always viable in healthcare, schools, commercial and industrial settings, where workers, students and patients are often in close proximity to others.  For these environments, a solution is needed that can kill airborne viruses and also kill viruses on surfaces, so that the risk of transmission can be reduced. 

The PYURE Company markets commercial air purifiers that have been proven to kill viruses and bacteria in air and on surfaces.  PYURE manufactures its air purifiers in Florida, using proprietary UV irradiation technology to safely generate hydroxyls and organic oxidants.   Unlike conventional air purifiers, PYURE devices do not limit treatment to the air that passes through the unit.  The hydroxyls and organic oxidants generated diffuse throughout a room, sanitizing air and surfaces in the treated space.  PYURE devices are safe for use in occupied spaces and do not degrade plastics, rubber, fabrics or electronics.   The levels of hydroxyls and organic oxidants produced are equivalent to the concentrations found outdoors in nature and well within the safe limits established by OSHA.

PYURE’s hydroxyls are ideal sanitizing agents. They react with a broader range of chemicals and are a million times more reactive than ozone, bleach and other agents.  They react so fast that they are consumed within a few milliseconds and never accumulate.  Atmospheric hydroxyls are continuously produced by the action of the sun’s ultraviolet energy on oxygen and water in our atmosphere.  They keep air safe to breathe by decomposing natural and man-made pollutants and killing pathogens.  They sanitize air and surfaces through a natural process called lysing, where the hydroxyls react chemically with the lipids, proteins and carbohydrates in the cell wall membranes of viruses, bacteria and other organisms.  The interior contents of the cells leak and the pathogen is destroyed.  The mechanism for killing pathogens is not biological, so viruses and bacteria do not develop immunity.

PYURE conducted several studies in independent labs to demonstrate the safety and efficacy of its technology in destroying pathogens, both in aerosolized form and on surfaces.   These included surface decontamination (porous and non-porous) studies on bacteria, viruses and mold, where a 99.99% reduction of Influenza Type A was achieved within 3 hours. 

At the Aerosol Research & Engineering Laboratories (ARE Labs), a U.S. laboratory specializing in the study of aerosolized microorganisms, PYURE conducted an evaluation of the kill rate on a number of pathogens, including MS2 bacteriophage (ATCC 15597-B1), a positive-sense, single-stranded RNA virus.  The FDA routinely uses MS2 as a simulant for pathogenic RNA viruses such as coronavirus. The device tested (MDU/RxTM) demonstrated a reduction of over 99.99% of MS2 virus in air within an hour, achieving a 99% destruction in 15 minutes (see graph below).

HGI leveraged its safety and efficacy data to obtain FDA approval for the Odorox® MDU-RxTM (FDA 510k #133800).   The MDU-RxTM is approved as a Class II medical device for use in occupied spaces.

PYURE sells a line of portable devices that can treat offices, classrooms and other spaces, from a few hundred to several thousand square feet.  These units are “plug and play” – they are plugged into the wall and turned on – no calibration needed, no training, no cleaning or maintenance.   PYURE also commercializes several models that can be mounted into air ducts or on a wall.   PYURE also sells large systems that are integrated into HVAC or air handling units and can treat hundreds of thousands of ft2.   These systems require custom design and installation and have longer lead times.

About The PYURE Company

PYURE  is a private company that manufactures and markets commercial purifiers to cleanse, deodorize and sanitize air and surfaces.  PYURE’s novel, patent-protected hydroxyl technology replicates the way sunlight sanitizes the outdoor environment by safely generating and diffusing hydroxyls and organic oxidants indoors.  PYURE markets a range of products, from portable devices treating hundreds of square feet to HVAC integrated solutions that treat hundreds of thousands of square feet.  PYURE products can be purchased directly or through authorized distributors.  PYURE is located in Boynton Beach, Florida.  For more information, visit
