Foam or cloth filters can be washed. I wash by hand with hot water and dish washing liquid, rinse with clean water, thoroughly dry and refit. Has always worked for me. The paper filters obviously can't be washed, but if you have access to a compressor you can blow them cleaner. Be careful as they do rip easily and this method only partially unclogs them. Replacement is the best way.
