We understand that there is no "one-fits-all" solution to air purification. That's why our products utilize multiple technologies to address specific needs. Learn more about the technology we use below.
ODOGard®
ODOGard, our advanced technology, forms bonds with contaminants, inducing molecular changes that render them inert. This means that particulates as small as 0.3 microns, including pollen, allergens, mold, dust, pet dander, bacteria, and virus carriers, are not only trapped but eliminated at a molecular level. As a result, these contaminants won’t return to the airspace, ensuring that you can breathe not only fresh and clean air but also odorless air, thanks to the transformative power of ODOGard.

Filter Merv Ratings
MERV (Minimum Efficiency Reporting Value) measures a filter’s effectiveness in capturing airborne particles. Traditionally, the higher the MERV rating the higher the filtration, however high MERV ratings put a greater strain on the HVAC system, until now. Our revolutionary new filter solves the problem of having to sacrifice efficiency to achieve greater filtration.

Fresh Essentials™
MERV 8A Filtration
Clean air for everyday living.
Designed for households looking for reliable dust and odor control. With ODOGard® built-in, it tackles everyday odors like cooking, pets, and smoke with basic filtration performance.

Paws & Pollen™
MERV 11A Filtration
Enhanced protection for allergy and pet-sensitive spaces.
Upgraded performance that captures more allergens, pollen, and pet dander—plus the same powerful odor removal with ODOGard®.

Ultra shield™
MERV 13A FILTRATION
Maximum Protection-down to virus carriers.
Our highest-rated residential filter captures ultra-fine particles including bacteria, virus carriers, and smoke particulates. Engineered for homes that want hospital-grade filtration with household odor control.
HEPA Filtration
Greentech has taken the industry-leading HEPA filtration technology to the next level. Our HEPA+ line is powered by the odor-eliminating power of ODOGard. Combined, this filter removes VOCs and odors better than any other standard HEPA filter.
Photocatalytic Oxidation
Photocatalytic Oxidation (PCO) uses a broad-spectrum UV light and moisture in the air, creating active molecules to seek out and diminish pollutants at the source.
Bipolar Ionization
Bipolar Ionization creates negative and positive charges that remove dust and other particulates from the breathing space.
Ozone
When ozone is released into the air, it actively seeks out and attaches itself to various pollutants, including bacteria, viruses, and airborne particles. This molecular interaction initiates a powerful oxidation process, effectively breaking down and neutralizing these contaminants.
