Pros: -Individually wrapped. May be useful for some people or use cases. (handing them out to others?) -Fit nicely -Adjustable/bendable nose piece.

Cons: -Individually wrapped. Bad for the environment, annoying to open each one if you don't want them individually wrapped. (within a family unit or one person) -I guess disposable masks are bad for the environment in general if we're going there. Individually wrapped in plastic makes them even worse though.

Overall Review: I guess they are fine. Seems like "dust masks" used to be way cheaper? Is KN95 =< N95?

Pros: Worked well while it was working. I can't recall the setup, but I guess it was fine.

Cons: Died in a year and 8 months, which sounds about average from the other reviews. High pitched squealing sound, no lights on.

Overall Review: Don't buy unless you want to replace it in a year or two.
