Alpha-Pur - Rigid Cell Air Filters

Rigid Cell Filters are engineered to withstand fluctuations in airflow and are ideal for variable flow, variable volume HVAC systems. Rigid Cell filters are enclosed and contain either synthetic media or fiberglass media in multiple efficiencies. Rigid cell filters look similar to pleated filters but have a depth of 6-12 inches and are surrounded by a galvanized metal or plastic frame.
