When you improve air quality, you improve learning. The EPA agrees that improved air quality in the classroom equates to reduced absenteeism, better test scores, and enhanced productivity. That’s why Greentech’s unique combination technologies work 24/7 to reduce airborne volatile organic compounds (VOCs), allergens such as pollen and pet dander, and odours caused by mould, bacteria and other pollutants. 

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, 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 new standard in air purification is the innovative Active HEPA+, utilizing a powerful fusion of active and passive technologies. Backed by an 3-year warranty, it’s the ideal solution for fast and continuous odour remediation in long-term care facilities. And it’s proven to inactivate 99.98% of the virus that causes Covid-19, something important to all of us these days.

  • The only purifiers to combine both active and passive air purification technologies.
  • ODOGard® treated HEPA filtration for quick odour remediation of odours caused by mould, bacteria and other pollutants.
  • Reduces volatile organic compounds (VOCs) allergens, such as pollen and pet dander.
  • Proven to inactivate the virus that causes Covid-19 from the air.

*Laboratory tests prove to inactivate over 99.98% of SARS-CoV2 in the air within ten air exchanges in a controlled environment.
