An economical alternative to refillable trays used in granular media housings, AmerSorb BP panels are easier to handle and reduce maintenance costs. The patented process uses a polymeric substance to bind activated carbon into a rigid, uniform structure characterized by open pore structure. This bonding process is unique because adsorption properties of the base activated carbon remain virtually unchanged. 
AmerSorb BP carbon bonded panel filters are constructed with 0.25 oz. high-loft, non-woven polyester front and back for protection during shipment and offer particulate removal capabilities as well. Structurally designed to prevent bypass of contaminated air, the carbon is “locked” in place and will not settle, as often occurs in loose-fill trays and honeycomb carbon filters. AmerSorb BP bonded carbon panel filters contain approximately 5% more carbon by weight than a comparable size loose-fill panel filter.
