MDH and CDC guidance for using paper bag to extend the life of N-95 respirators but not surgical masks

Paper bag with handles 8.5" x 6.5" x 3.5"  Name and date are clearly marked on the bag

Respirator straps are hung from paper bag handles

The respirator is suspended above the bottom of the bag

A 2 gram desiccant pack is placed at the bottom of the bag to absorb moisture from the mask to slow down bacterial and fungal growth. The amount of desiccant needed may vary dependent on storage conditions.

Please see the disposable respirator post for links to the Minnesota Department of Health and the CDC for the number of times these respirators can be used. Guidance on the number of uses will vary by health care provider. The length of storage time will vary from 5 to 7 days. This is based on the anticipated COVID-19 survival time on surfaces.

Experience from nurses indicate that moisture in the masks is an issue. The straps also tend to wear out after repeated use.

To reduce particle loading on the mask, staff are asked to refrain from wearing make-up in areas that will contact the surface of the mask.

Surgical Masks:  Surgical masks provide some protection from droplets but they are primarily designed to protect the patient from the provider because the mask does not provide a tight face seal. Never reuse, wash or disinfect surgical masks.
