My Black & Decker Dust Buster 9.6 volt handheld vacuum cleaner model is several years old and apparently no longer available. When I ran out of filters I took a chance and ordered this non-Black and Decker generic filter and it works great. In contrast to the original filter, this one is made of hard plastic and is not flexible. Otherwise it is exactly the same as the original filter. Just make sure it fits your vacuum cleaner model.
