This item will only fit vacuum cleaners that accept the "CN-1" bag; We think it's usually (or maybe just) a GE® or Eureka® canister vacuum. Got 30 today for about $1 each, which is excellent value compared to other options on Amazon or in store. The packaging that arrived today has been 'repackaged' and we could have used a lot less packaging, tape etc; However, we received 10 3-packs. This CN-1 vacuum bag, fun little shape, works like a charm. Use this or similar items with our GE® cylinder vacuum cleaner for years and everything will be fine! Highly recommended. PS Much more useful and smarter, in our opinion, to have a placement operation in Telluride, Colorado than "bagless" vacuums that require you to dump dirt and dust into a garbage bag. You fill up these CN-1 pouches after a few uses and throw them away. Ideal.
