Can you reuse a face mask? It won't be as effective if you do facebook Images By Tang Ming Tung/ Getty Images Unlike cloth face masks, disposable masks like surgical masks and N95 respirators should be thrown out after one use. As a last-resort measure in emergency situations, it is possible to extend the life of a disposable face mask if extreme care is taken. If you use a reusable mask, make sure to wash it once a day and consider a double-mask with two-to three layers of fabric, for added protection. Whether or not you should reuse a face mask depends on the type of mask.
