Looking at bags for it, I see Type N, and I see Type MM. How do I know which type this one uses? I didn’t get the manual with it, and it doesn’t tell me on the data tag.
V.A.C. does make a HEPA bag in at least one of those.
Is this orange Model 3671-A less common? I see Model 3670 everywhere, but not so much the 3671.
