Tri-X Filter (65 sq. ft.)
Traditional filters rely upon the paper media to catch particulates in a single pass. The Tri-X filter not only filters by using the element’s surface area, it also uses the media’s depth (third dimension). Because it filters by depth rather than just surface filtration, Tri-X filters ten times more gallons per square foot than other filters and it provides over twice (65 sq. ft.) the filtration area of a standard (30 sq. ft.) filter. The Tri-X filter is made to last up to 5 years!
