Activated carbon air filters, also known as charcoal impregnated air filters, are widely recognized as an effective method of removing and preventing odor/fume buildup in recirculated air.granular activated carbon manufacturer Utilizing the finest quality coatings, Permatron offers a line of high efficiency odor, fume and gas removing activated carbon commercial 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.
Charcoal impregnated air filters are highly effective for organic based odors. Activated carbon, mixed with alumina and potassium permanganate 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, an activated carbon commercial air filter absorbs odors and fumes into its media. The odor causing molecules are actually removed from the air permanently, not masked with another odor.
Air velocity, humidity and temperature can influence the odor elimination. At times of high odor generation, air should recirculate through the activated carbon filters to achieve maximum effectiveness.coconutactivatedcarbon.com The rate of adsorption depends on the relationship between the pore structure, or surface area, and the shape of the contaminating molecules.
