Polylok Poly-Air - Model PCF-PLVF - Odor Control Carbon Vent Brochure

The Poly-Air odor control filter is an activated carbon vent stack filter that can be used in plumbing vents to remove offensive odors, such as Hydrogen Sulfide. Odors can be caused from sewer or septic system gases that vent from a residential home or commercial business. As the gases and odors come out of the roof vent stack, this carbon filter eliminates these unpleasant odors.
