The closest simple solution for you would be either part number 2071 (P95), or some new filters 3M made that are P100 but designed to be easier to breathe through. I’ve leveraged 3M’s filter selection poster a lot for reference, you can generally assume that all of the filters here fit your mask: The mating between 3M masks and 3M filters/cartridges is universal – either 40mm threaded mounts (like gas masks), or the 3M bayonet style mount. The below is based on my best understanding, it’s not gospel. Standard disclaimer, I’m not a doctor, lawyer, medical expert, 3M rep, or even a particularly good cook. It sounds reasonable, but I don’t know to what extent this has actually been tested. I don’t want to spread any false information, so please take this with a grain of salt. I don’t know how good this information is or if it has any validity. I’ve also seen descriptions of baking disposable masks at a certain temperature to kill the virus faster, however in the case of cartridges I imagine the plastic would make that a poor idea, since it could melt.

In the case of the N95/N100/P100 filters, there is a lot of talk about leaving them somewhere isolated, or in a sealed bag, for 4 or 5 days to let the virus in them die, before using them on a mask again, and then you can get several uses before they’re “used up”. If the o-rings start to go or the mask leaks, you can get maintenance kits too, though I’m not sure how commonly they’re sold and for the price of a new mask, if you used it that much just replace it entirely is my theory.įor the filters, once they’re “used up” (which is a really, really vague and hard to determine amount of time), you pretty much chuck them. 3M also sells specific cleaning wipes for masks. My current understanding is that for the mask itself, a wipe down with a clean damp cloth, or alcohol wipe, is pretty much all it needs.
