Trane/American Standard PERFECT FIT Washable Filter (BAYFTFR21W1A) 21" X 27" X 1" nominal size
A washable filter provides clean indoor air as it removes airborne pollutants. The Trane/American Standard Perfect Fit filter includes a MERV 5 rating. A factory original part, it captures large airborne dirt, dust, pollen and odor particles. Simply wash the filter every three months. With cold water, spray it against the airflow and allow it to dry completely before reinserting it. Made without foam or metal materials, the filter remains free of clogs and rust for a lifetime.
MERV stands for Minimum Efficiency Reporting Value, and measures a filters’ efficiency in removing small particles. The higher the MERV rating, the more particles the filter can remove.
