QualityFlow Extreme rigid filters are designed to handle high airflow and provide low pressure drop. The QualityFlow media stands up to turbulence and abrasion that typical medias cannot withstand. QualityFlow media also provides 50% lower pressure drop than standard rigid box filters to relieve strain on motors and reduce energy costs, while providing twice the dust holding of standard rigid box filters.
