When worn properly, a person wearing a non-medical mask or face covering can reduce the spread of his or her own infectious respiratory droplets.
Non-medical face masks or face coverings should:

  • allow for easy breathing
  • fit securely to the head with ties or ear loops
  • maintain their shape after washing and drying
  • be changed as soon as possible if damp or dirty
  • be comfortable and not require frequent adjustment
  • be made of at least 2 layers of tightly woven material fabric (such as cotton or linen)
  • be large enough to completely and comfortably cover the nose and mouth without gaping

Some masks also include a pocket to accommodate a paper towel or disposable coffee filter, for increased benefit.
