Bosch BBZ152HF Formula Series Hepa Filter

The description invites us to compare this to genuine Bosch part # BBZ152HFUC. OK, I'll compare it: after you discard your old Bosch filter and install this one, you'll discover that it's a loose, sloppy fit. It looks the same as the Bosch filter, but without putting a micrometer on it, it must be slightly smaller because it doesn't snap into place the way the Bosch does.Oh well, I'm hoping the lid of the vacuum holds it in place and that I don't end up ruining an expensive vacuum cleaner by saving a few bucks on a no-name, "compare to" filter.
