Replace it
Those washable filters are terrible to clean out. If you don't use a blower of yours, I'd recommend switching over to this other filter instead whether it's genuine or generic. Try to run it without the filter first to see if it's still making a weird noise or not. If so, then you should bring it to a shop.
