It is a good idea to have a spare or replacement filter on hand, as they may need to be washed depending. This is typically an easy job that can be safely done at home. If you find yourself with dirty or clogged filters, avoid long downtimes and skip straight to the laundry room by washing them in your machine. Do not use any other cleaners on the filters other than soap and water, as this will damage them even further.
 
It is important to clean the filters with compressed air before washing them, because excess dirt or other residue on the filter will be transferred to the laundry water. The laundry machine's drain hose should be filled with enough water to allow proper drainage of dirty water that may drain into it. Place the dirty filter in the water, and turn on the washer to its normal cycle. Depending on your machine, this cycle may take anywhere from 5 minutes up to 30 minutes.
