Re-using a disposable mask right away
Disposable masks are technically meant for single-time use. However, if you’d like to re-use yours, there is a safe way to do so. Put it in an enclosed paper bag for at least three days. During that time, any virus that may have been on the mask should die. But do not re-use a disposable mask, one day after the other as it could be contaminated. Using this paper bag method, you’ll need several masks you’re constantly rotating.
