Filterbuy's 16x25x4 replacement air filters are designed for your furnace, air conditioner, heat pump, or HVAC system. With an actual size of 15.50" x 24.50" x 3.63", these filters feature MERV 11 synthetic media (comparable to MPR 1000 - 1200 & FPR 7) that protects homes from pets, allergies, and more by trapping 95% of airborne particles without impacting airflow.

The electrostatically charged, pleated filters capture more harmful particles, last 3 times longer than fiberglass models, and are 100% manufactured within the United States. The 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.
