18"X20"X2" ULTRA 12 FILTERS
This filter is a MERV 8 and was tested according to the procedure described in appendix “J” of the ASHRAE 52.2 standard. The media (filtrating material) is held by a solid die-cut cardboard frame that is waterproof and made of 100% recycled material. The diagonal lines on each side are glued to the media to assure a greater rigidity and to maintain the desired space between the pleats. The cardboard frame is made of two parts that are glued to the media all around. A metal wire netting is also glued to the media to maintain the pleats and offer a greater stability. All of the frames are treated with a waterproofing product (Aqua Coat).
