Buy the OEM. It's cheaper.
No, but it make emptying much more tidy. You like tidy, right?
Pfffft. Probably not. You should have bought a Rigid.
Its inside diameter is 4.375".
This item is model 09093.
Probably not. I don't have a lot of faith in this aftermarket garbage after this past experience.
A Rigid filter will be less money and probably fit. I see your question is two years old. Hopefully you got sorted out by now.
Yes, it will fit a model wd09350.
Yes. I bought mine for my 13 yaer old 16 fallon Craftsman wet/dry vac and it fits perfectly.
Don't get your hopes up.
