When wearing and using an n95 mask the n95 mask is meant to be used only once and then thrown out and replaced with a fresh new clean one.
However you can safely and easily hand wash the n95 mask about 3 times and then allow the mask to dry out by hanging it outside or in your home.
Researchers have said that you can wash and reuse the n95 mask at least 3 times before it will break down and should be thrown out.
The n95 mask is a harder to get mask so some people have been washing them and have had no problem with washing the n95 mask.
But it's best to throw the n95 mask out if possible and get fresh ones to wear.
But sometimes you do have to wash things that are not meant to be washed.
