The Flanders 225 Series 225RT-2025 Ring Panel Filter is a two-ply polyester panel with a 7 MERV efficiency rating. These 20" x 25'' filters are constructed by heat sealing layers of synthetic filtering media over a corrosion-resistant steel support frame. 225RT filters feature an overcut of media forming a built-in gasket between the wire frame and the holding frame. The overcut prevents air from bypassing your filter and secures your filter in place, allowing it to be installed without the use of retainer fasteners. 225RT filters are constructed with a 1" nominal media using a 3/4" nominal polyester media with internal tackification on the upstream and a 1/4" nominal white polyester media on the downstream. These filters are UL 900 class 2 listed for flammability and are 100% moisture resistant, extending the life of your filter.
