Flanders Permaire 36 In. x 360 In. x 1 In. MERV 5 Trimmable Air Filter

Cut-to-fit series Permaire Service Roll is a filtration media roll constructed of Permaire, which are synthetic fibers coated with resin and baked together. A single cut across the roll will product a ready-to-install filter pad. This odorless filter is a self-supporting, washable filter with a long service life and strong structural integrity. Removes 60-80% of synthetic dust and 20-30% of particulate matter and gaseous material from the airstream. The maze of fibers in a Permaire filter create an electrostatic charge to catch and hold airborne contaminants. Perfect for filter service professionals. Washable.
