Query: Wrong filter for the pet vac

While this filter says it is for Cyclonic Action Dustbusters, it does not fit the Black & Decker Pet Vac Cyclonic Dustbuster. YOu will need HVF91 replacement filter for that. This one looked like the right one, and since it says it is for the Cyclonic Action Dustbuster, I ordered it as well as the Hvf91 filter - which did NOT look like the right one, but apparently the replacement filter is different than original. it fits and works just fine. So....while the VF100 filter is probably just fine, be careful not to assume it will work with the Pet Vac.
