Review on Replacement Craftsman 9 17912 Genuine 5 Layer by Amanda Romero

Worked fine with my 6.2 gallon Master, but you have to use the nut that came with it and 'store' the original Master nut somewhere. Keeping a small piece separate is always risky as it can easily get lost or you forget where you put it. I was very impressed. No dust bypass with plaster dust, cold ash or drywall dust. I would have preferred a slightly tighter fit, but it's sealed so it's fine. Excellent value for money for a HEPA filter.
