Filterbuy 20x25x4 Air Filters MERV 11 for Allergen Defense (4-Pack)

Actual size: 19.50" x 24.50" x 3.63", these 20x25x4 replacement air filters are designed for your furnace, air conditioner, heat pump, or HVAC system. Crafted with MERV 11 synthetic media, comparable to MPR 1000 - 1200 and FPR 7, these filters effectively trap 95% of airborne particles, shielding your home from pets, allergies, and more without compromising air flow.

Featuring an electrostatically charged, pleated design, these filters capture more harmful particles and have a lifespan three times longer than traditional fiberglass models. Proudly manufactured entirely within the United States, these filters boast industrial-grade beverage board (recyclable) frames with dual wire backings, which enhance structural integrity and outperform standard cardboard designs.

In the event that 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 precisely as described. Designed to provide reliable, long-lasting performance, these replacement air filters offer peace of mind and superior air quality for your home or workspace.
