Q. When should you wash or replace the mask?

Answer

Cloth masks need to be washed regularly. Cloth masks may be washed by machine or by hand with warm water and detergent. When using the mask, make sure it's completely dry. N95 respirator masks and disposable respirator masks must never be rinsed. If disposable masks or N95 or similar respirators become broken, unclean, or damp, they should be discarded.
