You have the ability to change the air you breathe, no matter where you are. That includes the inside of vehicles, where air can be filled with volatile organic compounds (VOCs), odors and pathogens. That’s why Greentech’s unique combination pureAir technologies work in many different environments to reduce airborne VOCs, SARS-Cov-2*, allergens such as pollen and pet dander, and odors caused by mold, bacteria and other pollutants.

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

Combining Technologies for Cleaner Environments

A powerful fusion of active and passive technologies. 

Our proprietary 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, along with our proprietary ODOGard®-treated HEPA filtration, and you have a purifier unlike any other, continuously cleaning your space, reducing pathogens and destroying odors from the air and surfaces, 24/7. 

What’s in the plus?

Only Greentech has the filters with the plus. Our HEPA and MERV-rated pleated filters are treated with ODOGard® coating, which instantly bonds to odor molecules, completely clearing rooms of odors in as little as 10 minutes.

The pureAir 750+ Mobile

Providing continuous air purification, this permanently mounted unit is perfect for the transportation industry. pureAir 750+ Mobile features the same active air purification technology developed and used by NASA, and has proven to deactivate 99.98% of the virus that causes COVID-19 from the air.*




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.”
