High-efficiency, long-life replacement filter for Trane Perfect Fit media air cleaners. It captures a significant amount of airborne particles in the air that circulates through the filter.


  • Higher efficiency and lower pressure drop than OEM filter.
  • Captures particles as small as 0.3 microns.
  • Pleated filter for greater media capacity.
  • Low pressure drop reduces strain on equipment, provides a comfortable air flow, and helps maintain equipment efficiency.
  • Easy installation. Angled edge fits neatly into offset side of air cleaner frame.

Replaces the Trane BAYFTFR21M.
