Health care masks

Also known as surgical masks, these are loosefitting disposable masks. They’re intended to guard the wearer from call with droplets and sprays that may possibly contain germs. A health-related mask also filters out substantial particles in the air when the wearer breathes in.

  • Wash your fingers immediately after eliminating your mask.
  • On a regular basis clean cloth masks in the washing machine or by hand. (They can be washed alongside with other laundry.)
