Maintenance & Care

Cooper&Hunter recommends cleaning your screen filter every two weeks using a vacuum with a soft-bristle brush attachment. In dusty or high-use environments—such as garages, restaurants, or homes with pets or indoor smoking—the filters can also be gently washed with warm, soapy water. Allow to dry completely out of direct sunlight before reinstalling.

⚠️ Never operate your system without the filters installed. Consider keeping a second set on hand to swap during cleanings.

Replacement Guidance

Even with regular cleaning, reusable filters lose effectiveness over time. For best performance and air quality, we recommend replacing the screen filters every 12 to 24 months, depending on your environment and cleaning habits.
