The Flanders 425 Series 425LT-12120-24 Ring Panel Link Filter is a four-ply polyester link panel filter made by sealing individual ring panel filters end-to-end. These 12" x 120'' filters have a 10 MERV efficiency rating and are constructed by heat sealing layers of synthetic filtering media over a corrosion-resistant steel support frame. 425LT 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. 425LT filters are constructed with a 1-3/4" nominal media using a 1-1/2" nominal white/green/white tri-density, multi-denier 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.

100% Moisture Resistant
Moisture resistance prevents potential damage due to dampness, extending the service life of your filter.
Galvanized Wire Frame
A galvanized, corrosion-resistant wire frame provides added support to your filter.
Extra layers of media provide added levels of filtering.
