Clean Obsessed Type MM Micro Paper Vacuum Bags for Eureka & Sanitaire (9-Pack)

Selgo Vacuum Parts describes this Clean Obsessed Type MM bag as a 2-ply micro-filtration paper, and Clean Obsessed sells it nine to a box, part CP211, sized for Eureka and Sanitaire machines that take a Type MM bag.

Sanitaire's own commercial catalogue is the useful cross-check on what a Type MM bag belongs in: it lists its MM paper bag against the S3680, SL3680 and SC3680 series canister vacuums, so an MM bag is a canister bag rather than an upright one. If your machine is one of those, this is the bag opening you are matching.

The two-ply construction gives the paper more surface to trap fine dust before it works loose again, which matters most toward the end of a bag's fill when a single-ply bag tends to let more dust slip through. The collar matches the standard Type MM opening for a direct swap.

• Part: CP211, 9 bags per box
• Fits: Eureka and Sanitaire machines using a Type MM bag, including the S3680, SL3680 and SC3680 series canisters
• Filtration: 2-ply micro-filtration paper

Check the collar stamp on your current bag before ordering, since Eureka and Sanitaire have both used several bag types and Type MM is only one of them. A bag that feels unusually light for how long it has been installed may not be seated correctly rather than genuinely needing a change.
