Package of two (2) White-Rodgers F825-0628 super heavy duty odor removal activated carbon filters. Recommended for heavy smoke removal. Each filter measures 16 x 12½ x ½ thick. Filters are very dense, each weighing 1 lb. each.

This filter mounts behind the collector cell and before the fan. This filter is sandwiched in the blue plastic post filter frame.

The activated carbon absorbs odors and fumes and should be replaced 2 times a year.

The carbon filter complements the collector cell that captures the particulate by capturing the noxious gasses. The carbon is finely ground resulting in millions of 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 VOC's.
