Easily washable, this air filter lasts longer than the standard, disposable filter. This air filter replacement part is made to fit the shop air filtration system. As a genuine replacement part, this replacement filter installs exactly in place of the old one. This efficient air filter uses electrostatic technology to filter and trap particles like non-metallic dust, wood dust, dirt, and other containments. To keep your inner filter clean, you'll want to clean out the trapped particles once every 1 to 2 months.
