Filterbuy 20x20x4 MERV 8 Air Filters (2-Pack)
Category: bnx trufilter 20x20x1
The actual size of these 20x20x4 replacement air filters is 19.50" x 19.50" x 3.63", designed for use in your furnace, air conditioner, heat pump, or HVAC system. The MERV 8 synthetic media, comparable to MPR 600 and FPR 5, effectively protects your home by trapping 90% of airborne particles such as dust and pollen without impacting airflow.
These electrostatically charged, pleated filters capture more harmful particles than standard fiberglass models, and they last 3 times longer. Importantly, they are 100% manufactured within the United States.
The frames of these industrial-grade filters are made of beverage board, which is recyclable, with dual wire backings that improve structural integrity and outperform standard cardboard designs.
Please 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.
