Vacuum bags — store spares flat and dry
Vacuum bag
Vacuum bag tip: store spare vacuum bags flat in a dry spot so the cardboard collar stays straight and seals tight when it is time to swap.

A bent or damp collar is one of the quiet reasons a new vacuum bag will not seal. How you store the spares decides how well they fit later.
Keep spare vacuum bags flat
- Keep spare bags in their box, lying flat, not crushed under heavy items.
- Store them in a dry closet, not a damp garage or under the sink.
- Do not fold the cardboard collar to make bags fit a smaller space.
- Note the bag type on the box flap so the right size is easy to grab.
Flat and dry is the whole beat. A straight collar helps the next vacuum bag seat on the first try.
