These six bags all meet the HEPA filtration standard of 99.97% efficiency at 0.3 microns, a rigid bag collar easily slides into the bag frame and snaps to the vacuum, and the bag seals automatically as it's removed.
New charcoal lining still filters particles 99.97% of particles down to .3 microns. Now it also reduces odors in the vacuum.
If you used the old M12H6 bags, this is it's replacement.
Maytag no longer prints the box for these bags, or prints their name on the bags, they will come to you in a clear plastic zip bag.
