12x24x4 Z-Line HWR Pleated Return Grille Filters MERV 10 – Glasfloss (Box of 5)

The 12x24x4 HWR Z-Line Series MERV 10 air filters from Glasfloss are designed to be a MERV 10 replacement option for the Honeywell FC40R1037. They also make a great alternative to a 1″ filter for filter grilles that accept only a 1″ air Filter with the added life and efficiency of a 4″ filter. 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,
