It’s probably silicone with maybe a little pigment in it. If you just want to clean it, you can clean it with anything that won’t degrade the silicone. And not very many things will degrade silicone. You will know if you’ve managed to damage it because it will stiffen, crack, weaken, glaze over, or otherwise show signs of not being OK. All you care about is that it’s airtight.
Regular soap. Dish soap. White vinegar.
Isopropyl alcohol might swell it a bit. It shouldn’t be a problem if you don’t soak it in the stuff, don’t leave it on there for ages, and give it a few mintues time to evaporate before you use it or stick it in a sealed container. It’s pretty effective as a disinfectant.
The bleach might do some damage, although if you just did a quick wipe with a low concentration of it, it would probably take a lot of cleanings to noticeably degrade the seal or reduce the flexibility.
Dilute hydrogen peroxide is a slow and selective disinfectant, and not much of a cleaner at all except for things it chemically reacts with. It could theoretically attack the silicone, although I bet it would take a long time at 0.5 percent, and what you quote about their tests seems to match that.
Wipe it, rather than washing it (and wipe it one or two more times with water if you need to “rinse” off whatever you’re cleaning with). Make sure it’s dry before you put it away or put it back on. Don’t get water or cleaners on the filters. The straps might be less tolerant of some cleaners than the body.
If you wanted to thoroughly disinfect it or sterilize it, you would have more things to worry about. Notably getting into the cracks and crevices. If I had to sterilize something like that ath ome, I’d probably wipe it down with IPA, try to pick any crud out of any crevices I could get at, and then pressure cook it on a rack. But I wouldn’t do it very often. And I don’t think there’d really be a reason to do it at all.
HOWEVER, filters, especially high-efficiency non-woven filters that let you breathe easily, have limited lifetimes. Without valves, you’re exhaling through them and getting them damp, which will degrade them faster. The O2 Web page you linked to says to replace the filters every couple of weeks “for air pollution” (which I suspect means with working valves), and daily “in clinical settings”.
So if you can’t get new filters, cleaning the respirator is probably not your big problem.
I think I’ve ruined other silicone objects by soaking them in IPA (isopropyl alcohol, not the beer).
I think what I ended up doing was wiping the mask (the rim that touches my face) with a ‘baby wipe’ –sterilization seemed like overkill. A nurse I asked about this directed me to just use soap and water.
You’re right that filters are now the limiting factor for me continuing to use the respirator. Thankfully, I only need to use it, at most, a few times a week, and I had the foresight to buy several replacement filters when I purchased the respirator.
I’ll probably switch to the same masks most other people are wearing eventually.
