I bought 20 of the N95s two years ago after seeing a Ted Talk. Have shared them with our kids. We'll all use them when we're going to have contact with the public. Our daughter didn't have any gloves so we gave her a bunch.
Sharing is caring.
As per my DIL who works in a hospital, hubby & I will use the paper bag method between uses. After use, put them in separate paper lunch bags with name and date. Every time we shop we'll use the oldest dated mask and discard the bag. Will keep a set of fresh masks in the car along with the stash of gloves and hand sanitizer we've already got there.
Since we go out less than once a week, we should be fine.
