QualityFlow Rigid Cell Filter MERV 11 w/o Header


This durable filter is cost-effective, has the lowest pressure drop on the market, and lasts longer than standard filters while meeting LEED standards. QualityFlow 4" pleated filters are designed to handle high airflow and provide low pressure drop. QualityFlow 4" filters utilize a durable frame and media that stand up to turbulence and abrasion that typical media cannot withstand. QualityFlow media also provides lower pressure drop than standard mini pleat filters to relieve the strain on motors, which reduces energy costs, while providing high dust holding and long filter life. QualityFlow 4" pleated filters are available in MERV 11, 13 and 14 ratings per ASHRAE 52.2.
