The bags for these Oreck mini jerry cans seemed confusing when ordering. A few years ago I ordered a couple of 12 packs as I own two of these mini vacuums. When I went to reorder, all the numbers on my bags were no longer valid. However, the photo on the bag shown fits two of my 12 year old canisters, so I took a chance and ordered them. Although my canister isn't a Buster B model, my old bags said they would fit a Buster B. When they arrived I was very pleased to find that they were identical in size and shape. However, I will say that they look a lot better than my old bags. They are thicker, indicating that they are double walled. They also state that they are hypoallergenic. FYI my old bags are MCV-12, BB-280D, BB180, MV160 and BB280E.
