I posted on Dear Pandemic's facebook page and asked if KF95s can be reused if left for several days. This was their response
You can re-use KF94s if letting sit for a week-- jthe virus can't survive outside the body for long. Just use a breathable paper bag or open container rather than a plastic bag to not encourage growth of other microbes
I am interested in knowing what those of you who had your kids in full day school with masks suggest as far as masks for one day. Did you think its good to send a second mask for after lunch, some kind of bag to keep the mask in or what? I remember there was a little discussion about this, but my kids were home and interested to know what people think now.
