Remember when your workshop was actually clean? Neither do we. Control the mess, minimize cleanup, and protect your lungs with the WEN DC1300-AF1 1-Micron Canister Filter. With a sturdy rubber seal, as well as several times the surface area and finer filtration than a standard woven or fabric collector bag, this filter improves your dust collector's performance and longevity and helps keep harmful particles out of the air you breathe. The polyester filter medium and sturdy frame combine to trap dust and other particulate matter as small as one micron. The built-in top handle simplifies installation and connects to internal paddles to help keep your filter clean – half a turn in either direction knocks built-up dust off the filter and into the collection bag. Compatible with the WEN 3403 and DC1300; Shop Fox W1666, W1685, and W1687; and Busy Bee CX424, CT186, and CT118 dust collectors. Remember when you could breathe easy? Remember WEN.
