Disposable face masks work one time each; or as supplemental inner mask protection
These masks are sufficient for one time wear.  The ear straps easily detach after one wearing.  They are not substantial by any means, but great for last minute grab, as in car glove box, if a better mask is misplaced or malfunctions.  They do not feel very protective,  Currently I am using them to add protection with cotton masks lined with nonwoven interfacing, as an additional layer(s) of protection.
