I think that to finish this thread with a modicum of research is, no domestic vacuum cleaner is "True HEPA" (and that term is actually used on some brands, which is actually a very vague term), looking up the specifications for HEPA filtration, you find that there are several different grades of official HEPA filtration, and the original specification was to trap airborne radioactive contaminants in the 1940s...


Even this simple Wikipedia page shows enough information about HEPA specifications (check out the References and External Links for full details):
