20x25x4 Air Filter MERV 13 Glasfloss Z-Line – Box of 6

Glasfloss Z-Line MR-13 20x25x4 MERV 13 furnace filters are the ultimate upgrade from standard pleated air filters and excel where similar HVAC filters (Heating, Ventilation & Air Conditioning) fall short. These MERV 13 air filters also offer an eco-friendly design and excellent particle filtration including many viruses and allergens that aggravate allergy sufferers. The air filter frame is constructed of heavy-duty, moisture resistant beverage board incorporating post-consumer recycled materials making it very sturdy and easy to install and remove from your HVAC system (similar furnace filters can be difficult to install and remove if they are flimsy or have absorbed moisture). 100% synthetic, electrostatically-charged fibers are used to construct the pleated air filter media that will not support microbial growth or absorb moisture. All of the components are thermally bonded together for high durability and extended reliability, making the Glasfloss Z-Line Series the preferred air filters for residential homes and commercial spaces.
