Activated Carbon Filter - Odor Control

Activated carbon filter removes odors and fumes Permatron's activated carbon absorbs odors and fumes. Whereas the collector cell captures particulate, the carbon captures noxious gasses.

Permatron charcoal filters exceed manufacturer specs with 14 grams of carbon per square foot along with a low 0.06 wg air resistance.

The carbon is finely ground resulting in over a million square feet of surface area. The carbon is impregnated into the filter media and heat set. There are no loose granules, the filter can be rinsed or vacuumed.

Vapors are pulled by molecular action in to tiny pores and held. In manufacturing the carbon, the activation process creates millions of micropores. The pores are sized and formulated to remove common household VOC's.

Quality Construction
