This is a maybe too specific question, but answers for any ‘SARS-CoV-2-or-similar-mitigating’ thing like masks or respirators (that can be cleaned and reused) would probably be helpful and are definitely welcome.
Here’s the post that convinced me to buy one of these respirators:
Yes. The O2 Curve can be sterilized and/or disinfected. The O2 Curve has undergone sterilization certification studies with High Power Labs in the US. The Curve was processed through multiple cycles of both Gravity Steam Sterilization (121 °C for 35 minutes and 15 minutes drying time), as well as STERRAD® 100 NX® vaporized hydrogen peroxide, assessed for any signs of damage or wear, then mask fit tested again (using a new filter) to ensure the Curve was still functioning as intended. The Curve passed again with a mask fit test score of 200+, with the minimum passing score being 100. The O2 Curve has also been tested in single cycle autoclave protocols including the SciCan Bravo™ V21, and the SciCan STATIM® 5000 G4. The O2 Curve has also not demonstrated any appreciable material defects after multiple cleanings with commercially available disinfection wipes, such as Oxivir® Tb or CaviWipes™.
The first of the “disinfectio wipes” mentioned seems to mainly use some kind of variant of hydrogen peroxide:
I would somewhat-weakly conclude that hydrogen peroxide, e.g. from a retail drug store, would work to clean (NOT ‘disinfect’) the respirator for repeat, and even regular, use.
What else would work? Bleach wipes? Rubbing alcohol?

O2 Curve Review: Well Worth the Money—LessWrong
I’ve used it many times now, but never regularly; at most maybe twice a week, for a few hours at a time.
But it’s been a good while since I last used it, I want to document for myself how to clean it (the respirator, not one of the removable filters), and apparently the company that makes them has shutdown (and broken links to their support info).
I did find this: Frequently Asked Questions – O2 Canada, a defunct or never-setup Shopify site:
