According to the Ministry of Health, disposable masks must be changed:
- when they get wet
- if we have been in contact with contaminated environments, it is good practice to throw them in the undifferentiated
- we are seeing positive people at covid19
- when it is difficult to breathe with the disposable mask on the face.
Pay attention to the wording on the mask packaging:
R : stands for reusable, for which once used just sterilize the mask and disinfect it to use it again.
NR : stands for disposable
