Self-supporting Pleated Panel Filters w/o Wire Mesh

Hencolin’s self-supporting filter media does not require the assistance of a metal expanded mesh for molding, and is specially designed and manufactured to provide the same filtration efficiency, initial pressure loss, and service life as commercially available primary filters.
The self-supporting paper frame filter gives the customer another new experience, no more worrying about cutting the installer when installing or disassembling, and no more worrying about iron shavings or rust from the metal diffuser mesh getting into the air conditioning mainframe or the room.
Above all, Hencolin’s Diffuserless Primary Efficiency Paper Frame Filter is recommended, and when disposed of after use, it can simply be thrown away with the normal waste stream, eliminating the need to separate the metal diffuser mesh from the synthetic fiber filter media.
