Removes Common Contaminants

The VariSorb HC filter is designed for the effective removal of common indoor and outdoor gaseous contaminants at high airflows, to help mitigate Indoor Air Quality problems. The VariSorb HC filter is suitable for retrofit into existing HVAC systems and for specification in new construction. It can be used in equipment designed for 12″-deep, single header filters.


The VariSorb HC filter consists of eight 1″-deep panels assembled in a V-bank configuration. Constructed of plastic, the VariSorb HC filter features injection-molded end panels made of high impact polystyrene (HIPS) and extruded vertical components made of acrylonitrile butadiene styrene (ABS). All assembly is with non-volatile materials. The sturdy, corrosion-free construction resists damage during shipping, handling, and operation.


Choose from SAAFCarb media composed of activated carbon, SAAFOxidant media composed of a combination of activated alumina impregnated with potassium permanganate, or a blend of both. The media is contained in panels with a honeycomb structure. A fine mesh scrim on both sides of the panel retains the media granules in the honeycomb. SAAFCarb media effectively removes volatile organic compounds (VOCs), jet and diesel fumes, and hydrocarbons. SAAFOxidant media effectively removes hydrogen sulfide, sulfur oxides, formaldehyde, and nitric oxides. For general purpose air quality control, SAAFBlend GP (50/50) media is recommended.
