Our 15x16x1 air and furnace filters fit most HVAC systems. They stop particulates from entering the air supply by using a media made of a specific material. We have 15x16x1 air and furnace filters with fiberglass medias and others with 100 percent synthetic, non-woven proprietary medias. Our 15x16x1 air filters last 30–90 days and have a maximum DHC. The 15x16x1 air and furnace filters keep HVAC systems running at their highest efficiency, they’re made to the exact size, and they’re easy to install. You don’t have to worry about any more confusion with other filters. We offer free shipping on all orders of our 15x16x1 air and furnace filters.
