Pad and Frame Air Filter (1 Frame and 6 Pads) - 18" x 20" x 3/4"
Includes one Frame and PACK of 6 pads
The Pad and Frame Air Filter involves a permanent frame and replaceable filtration pad inserts. The permanent frame is constructed of space-age plastics that are resistant to corrosion, oxidation and deterioration. Filtering inserts are anti-microbial and are more efficient in capturing particles, such as dust, ragweed, pollen, etc., from the air stream, than standard fiberglass filters purchased at retail outlets. Filtering inserts are shipped in an easily stored packet.
