Looks like painting masks are at least P95 rated = same as N95 or FFP2 but with oil resistance.
If you have the luxury of selection you really want FFP3, P100 or N100.

Silicone rubber facepiece seals lot better than single-use mask/respirator but as mentioned keeping the rubber facepiece kosher is another matter.

The thing that really appeals to me is that the silicone facepiece offers better seal. Can't they be disinfected with alcohol?

I mean, those N95 dust masks are way too expensive and hard to get to treat them as disposables. I only have like 5.

Most people don't have 100 masks sitting around to be throwing them away after each errand. Can't you wash them or spray with alcohol?

Anyone else looked at the title of the thread and wondered "painting them with what?" :-//

Spraying the surface of a porous item won't work if there is contaminants in the weave of the filter itself. So your Cartridges if you plan on using them will need proper sterilization to kill off any bugs generally heat would be the only appropriate method.

The box below is some I brought early in the year for woodworking leaving my 3M cartridge mask just for painting. They are out of date medical masks ($0.11 each). https://www.bsnmedical.com.au/products/wound-care-vascular/category-product-search/masks/non-fluid-resistant/proshieldr-resistant.html They are shown as non fluid resistant so washing them is likely a no go too but some available are fluid resistant. Looking at the weave the material will be a non woven rather than paper so it will survive some fluid splash but unlikely to survive 'washing'.

No I won't be wearing them when out shopping or reselling them on evilbay to make a $ :palm:

Save your cash on placebo masks and spend it on dunny paper instead.   

Apparently it has hidden magical properties that many mere mortals into electronics are not aware of, yet   :-//

as well as filtering out corona from entering the nether regions if a few layers are strategically jammed in.

Billions of loo roll hoarders can't be wrong   :clap: :clap: :clap:
