For me anyway, I'm not tossing out a N95 mask after wearing it out and about for a couple of hours. Though I didn't buy them myself, and they were a gift to me, I find it odd to toss them out after a single use.Original Post Deleted
The security guard in my building complained to me that it must be expensive to toss my N95 mask after a single use. It didn't dawn on me that one would do that.

For normal facial masks, if I go out for a couple of hours and not in a crowded place, I don't get the feeling that I need to toss them out. But maybe I'm wrong about that. I'm just surprised that people have told me how odd it is for me to reuse my mask.
