Activated Carbon Air Filters – How Do They Work?

2018-01-11 Share:


Activated carbon air filters are widely recognized as an effective method of removing and preventing odor/fume buildup in recirculated air. Utilizing the finest quality coatings, we offers a line of high efficiency odor, fume and gas removing activated carbon air filters that include bulk air filter media and pads cut to size, pleats, panels, high density granular carbon packs, bulk carbon and v-bank replacement trays.
Activated carbon air filters are highly effective for organic based odors. Activated carbon, mixed with alumina and potassium permaganate is highly effective for organic odors and light gases like ammonia, formaldehyde, hydrogen sulfide and sulfur dioxide. 1″ pleated type activated type air filters have approximately 3X the effective media surface of 1/4″ panel type activated air filters.  High density granular carbon packs and v-bank trays contain even more effective media.
Synthetic media substrates, like nonwoven polyester,  are impregnated with finely ground coatings, such as activated carbon, zeolite or alumina, and heat set to retain those coatings even when the activated carbon filter media is rinsed or vacuumed. Just as a sponge soaks up water, activated carbon filters adsorbs odors and fumes into their media.The odor causing molecules are actually removed from the air permanently, not masked with another odor.
