Perhaps a dumb question, but one Google couldn’t help answer.
If you have got a few FFP3 masks, would cycling them be a way to safely reuse them? For example, if I stored the mask I wore today to go to the shops for 3 weeks in a paper bag, could I wear that again in 3 weeks with there being virtually zero chance of the coronavirus being live on the mask?
I know they are intended to be disposable, but using them for a couple of hours at a time in areas that put them under a very light load (i.e. fresh or supermarket air, not a building site), is barely using the mask and is not compromising its structure.
I was surprised that there was no research into it.
