Cannot say for sure, but I believe Ryobi makes their own Filters.
Try putting in a new filter and see if that works. I also don’t remember reading if it is good for soap suds. Good luck
yes, the 49.90.1900 will work in the 0780.20
No that requires specific filter this will only fit the 1st gen and 2nd ten m18 wet/dry vac
I dont see why not.
Follow the directions in the manual. If you run with a wet filter you risk damaging the vacuum motor.
Yes, this is the one you need
Not sure what your seeing here. I bought the shop vac about 9 months ago. And bought some backup filters. Same part number. It stays to read safety label on filter. It’s hard to read, being in same color stamped on bottom of filter, but they are washable. All shop vac filters I’ve ever seen usually are. Just let em dry out for a day or so.
In a garbage can or bag. Tap the filter housing and clean out all the baffles until all debris/visible dust is free from filter. Then reinstall in unit. Do this regularly and the filter should last longer and vacuum will work better/more efficient. If HEPA compliance is a concern do not spray the filter out with compressed air as this may cause small tears/holes in the fabric making the filter no longer compliant.
