Filterbuy 20x25x4 MERV 8 Pleated HVAC Air Filters (4-Pack)

Designed to fit your furnace, air conditioner, heat pump, or HVAC system, these 20x25x4 replacement air filters (actual size: 19.50" x 24.50" x 3.63") provide reliable performance. Crafted with MERV 8 synthetic media (comparable with MPR 600 & FPR 5), these filters protect your home from dust, pollen, and other airborne particles by trapping up to 90% without compromising airflow.

Electrostatically charged and pleated, these filters capture more harmful particles compared to standard fiberglass models, while lasting 3 times longer. Proudly manufactured entirely within the United States, these filters feature industrial-grade beverage board (recyclable) frames with dual wire backings that enhance structural integrity, outperforming standard cardboard designs.

In the rare event that you receive items with a different label, frame, or media than pictured, please note that any such alteration is purely cosmetic - your filter will still function exactly as described, providing the same reliable protection and performance. Investing in these high-quality replacement air filters ensures your HVAC system operates at peak efficiency, maintaining optimal indoor air quality for your home or business.
