I just took apart my filter for the first time and I am not sure if I should replace or clean it. I have already hosed it down at a 45° angle all the way around a few times, but it is still quite grungy looking. Also it appears that the strap is gone from around it and some of the pleats have flattened out and distorted. The smaller inner filter looks about the same. I will attach some pictures and would appreciate any input you can give me as to whether I should clean or replace it.
