    • the third (middle) layer should be a filter-type fabric, such as non-woven polypropylene fabric
  • be large enough to completely and comfortably cover the nose, mouth and chin without gaping
  • allow for easy breathing
  • fit securely to the head with ties or ear loops
  • be comfortable and not require frequent adjustments
  • be changed as soon as possible if damp or dirty
  • maintain its shape after washing and drying

Filters

Filters add an extra layer of protection against COVID-19 by trapping small infectious particles. Consider wearing a mask that includes a filter or filter material as one of its layers, such as:

  • non-woven polypropylene fabric, which can be found as:
    • a craft fabric
    • the non-woven fabric that's used to make some reusable shopping bags
  • a disposable filter inserted into a pocket on the mask
Reusable masks with a non-woven filter layer should be washed daily, and can be washed multiple times. Disposable filters should be changed daily or as directed by the manufacturer.
