These replacement air filters for your furnace, air conditioner, heat pump, or HVAC system measure 19.50" x 20.50" x 0.75" in actual size. Crafted with MERV 8 synthetic media, which is comparable to MPR 600 and FPR 5, these filters effectively protect your home from dust, pollen, and other airborne particles by trapping up to 90% of them without compromising airflow.

The filters' electrostatically charged, pleated design allows them to capture more harmful particles than traditional fiberglass models, and they last up to 3 times longer. Furthermore, these filters are 100% manufactured within the United States, ensuring quality and reliability.

The industrial-grade beverage board (recyclable) frames, reinforced with dual wire backings, provide superior structural integrity and outperform standard cardboard designs. This enhanced durability ensures the filters maintain their optimal performance throughout their extended lifespan.

It's important to note that if you receive items with a different label, frame, or media than what is pictured, any such alteration is purely cosmetic, and your filter will still function exactly as described. The core properties and performance characteristics remain unchanged, regardless of minor variations in the product's appearance.

By trapping a vast majority of airborne contaminants, they help reduce the strain on your system, improve its lifespan, and ensure a healthier living environment for you and your family.
