The CI Supraloft® Polyester Group consists of non-woven high loft polyester manufactured by Columbus Industries for general-purpose HVAC filter applications. The collection of both rolls and cut pads is available in a wide variety of performance levels and thicknesses dry or tackified and with or without an anti-microbial additive. Each filter has high holding capacities due to depth-loading characteristics and graduated fiber density. Filter change out is clean, quick and efficient, and a long service life means the filters need to be changed less often. In addition to the polyester overspray media, CI also offers other even denser media to capture very fine particles for secondary operations. Tackified media is offered to capture very fine and dry particles behind primary HVAC filters.
