Glasfloss Z-Line 21 x 25 x 1 Exact MERV 10 ZL furnace filters excel where similar HVAC filters (Heating, Ventilation & Air Conditioning) fall short while also offering an eco-friendly design. 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 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.
