Indoor air quality (IAQ) is dynamic. Levels of pathogens, particles, and VOC continuously change based on countless variables such as people coming and going, activities taking place, and kinds of materials used in the space. Labs can’t recreate it. While the recent pandemic has increased awareness of the importance of air quality to mitigate pathogens, the continuous reduction of particles and volatile organic compounds (VOC) is equally important when creating a healthier indoor environment. For the hospitality industry, where people are constantly coming and going, we think that lab testing isn’t enough. That’s why, in addition to lab tests, we test our products in the field. After all, life doesn’t happen in a shoebox, so why rely on testing that does?

Combining Technologies for Cleaner Environments

A powerful fusion of active and passive technologies.

Our Photocatalytic Oxidation (PCO) technology uses energy to activate a catalyst, turning moisture in the air into products that continuously clean your space, inactivating pathogens and reducing odors. Combine that with Bipolar Ionization (BPI), which causes allergens and other irritating particles to drop out of the breathing space, and our proprietary ODOGard®-coated filtration, you have a purifier unlike any other, continuously cleaning your space, reducing pathogens and destroying odors from the air and surfaces, 24/7.


We’ve expanded the line of one of our most popular air purifiers, the pureAir 3000. Not every situation requires ozone, so we’ve modified the 3000 to include non-ozone options to fit the different needs of your customers. In lab tests, each unit has proven to be effective in reducing volatile organic compounds (VOCs), allergens such as pet dander and dust, and odors caused by mold, bacteria and other pollutants. Not only that, but these new units have also been proven to deactivate 99.98% of the virus that causes COVID-19 from the air.*

Improved indoor air quality for the hospitality industry helps:

• Reduce the risk of spread of COVID-19 and similar epidemics

• Create a cleaner environment by reducing VOC, allergens and other irritants, improving comfort for guests and staff

• Improve consumer confidence by continued investment in their well-being

• Reduce staff absenteeism

• Reduced odors associated with cooking as well as bathroom areas

• Greentech provides highly-tested active air solutions to SARS-CoV-2 and similar future epidemics*




* Laboratory tests prove to inactivate over 99.98% of SARS-CoV-2 in the air within 3:20 minutes in a controlled environment.

Test results don't lie

Combining our PCO+BPI technology with a HEPA filter treated with ODOGard inactivated 99.98% of aerosolized SARS-CoV-2 in as little as 3 minutes and 20 seconds in a 13ft^3 class III biosafety cabinet.

The proof is in the data, here’s more.

Extensive testing showed similar impressive results. TVOCs were reduced 99.9% and formaldehyde (HCHO) reduced to 33% of the original concentration. Both Total Particulate Matter (PM) and Respirable Particle Counts were significantly reduced during testing.

“Both qualitatively and quantitatively, there was a measurable and sustained reduction of odor and TVOC (total Volatile Organic Compounds) levels when the ODOGard unit was functioning in comparison to the initial levels found inside the room and the adjacent hallway during the 14-day testing period. The overall sub-micron particle counts were reduced the most.”
