Electrostatic Air Furnace Filter - Silver Metal Frame - Permanent and Washable

Product Review

All metal frame filters have a 1/8" tolerance. The SILVER PATRIOT 94 is designed to provide the highest filtering efficiency available for the majority of furnaces and air conditioners. The 0.12 inch W.G. initial resistance of the SILVER PATRIOT 94 will perform best in systems configured with 1 square foot, or more, of filter area for each ton of air conditioning. Two layers of woven monofilament polypropylene with integral anti-microbial material provide 10 times more filtration than a disposable fiberglass filter. The deep loading center layer of non-woven polyester allows the SILVER PATRIOT 94 to prolong the time between washings. All custom size filters are sized as ordered and non-returnable. All standard size filters are undercut by 3/8" to allow space for typical installation. Note: The sizes listed below are standard sizes so the width and length are undercut by 3/8 inches and the depth is undercut by 1/8 inch to accommodate standard air system openings. ALL FILTERS ARE EXACTLY 7/8" IN DEPTH.
