autoclaving is a time-tested way of sterilization. a hospital study suggested that the n95 mask could be recycled for up to five times, and still keep its filtering ability intact.
microwave? for one, some masks have minute metal parts (nose piece, staples) that are a no-no in microwaving.
but are they otherwise effective against covid? i don't know.
clorox, zonrox, or sodium hypochlorite?
i don't know. but they may leave an un-healthy residual that we do not want to breathe in...
i guess, that means, they still haven't come up with a uniform way to re-use masks.
