Features

  • 20x25x4 replacement air filters for your furnace, air conditioner, heat pump, or HVAC system (actual size: 19.50" x 24.50" x 3.63")
  • MERV 8 synthetic media (comparable with MPR 600 & FPR 5) protects homes from dust, pollen, and more by trapping 90% of airborne particles without impacting air flow
  • Electrostatically charged, pleated filters capture more harmful particles, last 3x longer than fiberglass models, and are 100% manufactured within the United States
  • Industrial grade beverage board (recyclable) frames with dual wire backings improve structural integrity and outperform standard cardboard designs
  • If you receive items with a different label, frame, or media than what is pictured, please note that any such alteration is purely cosmetic and your filter will still function exactly as described
