5 Best Disposable Face Masks - Jan. 2021 - BestReviews
If a disposable face mask becomes moist, you should remove it and throw it away. Most masks aren’t resistant to fluids, so they’re no longer effective when wet. Always examine a disposable face mask before you put it on to be sure there aren’t any holes or tears in it. Be sure to place a disposable mask on your face right side up.
