Fosshield® protected HVAC filters capture and neutralize a variety of potentially harmful and destructive microorganisms, while eliminating their offensive odors in indoor environments.


We spend a lot of time indoors. In fact, according to several studies, Americans spend about 90% of their time indoors; with 65% of that time spent in their own homes*.

Fosshield® protected HVAC filters reduce the growth of mold, mildew, and fungus on the treated surfaces, guarding the filters from these and other microorganisms, while controlling their offensive odors.
