Do's and Do Not's of Mask Use
For basic mask information see Everything About Masks to Prevent Infectious Diseases.
- Do place mask on face correctly. If the mask is not fit properly, it will not protect a person from infectious diseases. A properly fitted mask is sealed around the mouth and face prohibiting the entrance of air via any other means besides through the mask itself.
- Do disinfect reusable masks with replaceable filters between users. The filter must be replaced before next user.
- Do have your mask refitted if you: lose or gain weight, have scarring or surgery that may change the shape of your face. Tight fitting masks that have a replaceable filter need to be fitted to each user
- Do shave very well. Masks do not offer protection to people who have facial hair. Even stubble can affect the seal of the mask and therefore its ability to protect you.
- Do follow the manufacturers instructions regarding use.
- Do not reuse disposable masks. Viral particles, for example, can survive for many hours and sometimes days.
- Do not touch the outside of the mask. If you do touch the mask, wash your hands right away.
- Do not touch your face, mouth or nose.
- Do not share disposable masks.
- Do not use the respirator for situations it was not designed.
