Panel and Link Filters

Mr. John Stanley founded Tri-Dim with the vision of a media specifically designed for air filtration – thus the origin of Tri-Dek. Tri-Dek is a multi-denier, depth-loading synthetic media that has been constructed into a self-supporting panel filter that offers an excellent alternative to pleated pre-filters. Tri-Dek offers better efficiency, longer service life, reduced shipping charges, reduced air bypass, and fewer damaged filters than pleated air filters. Available in 2, 3, or 4 ply panels that can be linked together as pictured to create one filter for the entire width of your air handler – virtually eliminating air bypass around the filter.
