Replacement Cartridge Filters


Experience the UAS Filter Standard: ProTura® Nanofiber

dust collector cartridge filtersKeep your dust collectors running efficiently and energy smart with high-quality cartridge filters from United Air Specialists. Available in an assortment of media - including our proprietary ProTura Nanofiber - our cartridge filters rank among the highest in performance, efficiency and value.

Rated at MERV 15, replacement cartridge dust collector filters with our ProTura Advanced Nanofiber technology are up to 95% efficient on 0.3 to 1.0 micron size dust. These filters have a surface treatment of the finest synthetic nanofibers used in any current filtration product . Exceptionally small in size, these fibers are about 50% finer than the “other” nanofiber filtration technology, are more durable, with better moisture and temperature resistance and stronger adhesion to the media substrate.

Independently proven to achieve higher initial efficiency, cleaner air, lower pressure drop and greater energy savings than commodity filter media, our proprietary ProTura Nanofiber is the standard technology that we equip all of our cartridge dust collectors with. However, you can also choose from poly-glass and 100% spunbond polyester to meet all of your replacement filter needs. See the chart below for available replacement filter options from UAS.
