HEPA, but on a whole new level
Greentech has taken industry-leading HEPA filtration technology to the next level by weaving in the odour-eliminating power of ODOGard®. With both technologies combined, this filter removes VOCs and odours more effectively than any standard HEPA filter

HEPA vs HEPA+
Unlike other HEPA air filters on the market, Greentech is proud to exclusively offer HEPA+.
The "+" represents the filter coating, ODOGard. When combined, the ODOGard supercharges the HEPA filter to create outstanding results.

Active HEPA+
With our Active HEPA+ line, we take things a step further. Active means that there are active purification technologies at work. In combination with the passive technology found in HEPA+, this product is a very powerful tool for all air purification needs.
