We're also gearing up for likely exponential growth in Australia. A suggestion if you're thinking about reusing old n95 mask. (To be safe) Stick it under UVC light for 5mins both sides (A light that has between 200 to 280nm wavelength- a sterilisation box). It will irradiate any bacteria down to the DNA. You can likely get <2 reuses out of it before it completely compromises the material.
