If yours are the sponge type filters, those very thin sponge things, just run water through them from the back side so the dust falls off with the flow of water. I wring them out by hand with my fist (one hand), and then put them back. They are not perfectly dry, they are still damp, but they dry out very fast once air starts passing through them. I've been doing this for the last 15 years and it hasn't hurt any air conditioners I've owned yet (in the camper or window air conditioners in a house either).
thanks. I have those same filters. and thanks to the other posters I now have a source for the material. think i'll order one piece and keep it in reserve. appreciate all of the help.
