Cleaning AC filter

When we wash our AC filter and it dries there appears to be lint still stuck in it. Does anyone know what we are doing wrong and/or how to get rid of it?

    X2. I also buy the cut to size material and replace my filters every now and then.
  • I bought a bag of the foam filter material at ACE.
    My return filter is roughly 5" X 12"
    I cut out several filters then swap out a clean dry one for dirty one.

    Dirty one a place in kitchen sink with soapy hot water....then using kitchen faucet sprayer I blast it clean.
    Ring out and hang in shower to dry.

    Repeat at least monthly. When a filter stretches I toss it.
  • the filter is very easy and cheap to replace. might even be the cheapest item at a rv store.

  • Easy enough and very inexpensive to just replace it now and then. Cut to fit material available at any RV dealer service dept.
