Product review (5 stars): Perfect fit!
This generic replacement is priced right and fits perfectly.

I tried to wash our neglected filter, but nothing worked. I tried washing it in the dishwasher using the high-temperature option in pots & pans mode, but that did nothing. I tried using a steam cleaner, but that didn't work. I was about to try using my gas-powered pressure washer, but I decided that would be too much work. Just get this instead of wasting your time cleaning the old one. However, if anyone has suggestions on how to clean these, I'd love to hear from you. I have another one of these that costs $80 to replace, so I'd like to try to clean that one.
