I’m not in health care so my standards are my own, but I went to a reusable/washable mask a while back. It was sold under the Breathe Healthy brand on Amazon (no longer showing). They can be washed by hand or machine washed gentle cycle, then allowed to air dry. This seemed like a good way to go for someone not in health care.

That said, the mask is supposedly antimicrobial, but was only tested to 1.0 microns. Seems to me a mask could be made that would test better than 1.0 microns and could be cleaned and reused. Maybe not cheap, but better than long term use of a disposable mask.
