Most Pelonis dehumidifiers use a simple mesh filter that is detachable from the device itself. After that, you may clean it using water and a gentle detergent in the sink where it was done. Utilize a spray nozzle if at all feasible; however, be careful not to apply excessive pressure as this might cause the mesh material to get damaged. After that, you must wait for the filter to dry completely before you reassemble it and put it back into your dehumidifier.
