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 features a 3-pocket design with deep pockets made to trap more particles. The air filter purifies the air by trapping particles as small as 1 micron, including 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. You may need to clean the air purifier more frequently depending on how often you use your shop and how much dust your projects produce. When you remove the AFS-2000 inner filter, you can wash it or use air to blow out excess dirt and dust.
