The filtering material of the Air-T-Rex is thermally fused around a galvanized wire ring.
The Air-T-Rex is self-sealing to prevent 'Dirty Air By-Pass' common with ALL cardboard framed pleated filters
For a perfect seal, the filtering media has a flexible one inch 'selvedge edge' that exceeds past the galvanized steel frame to provide a complete gasket seal around the perimeter
