N95 masks are used in many industries to protect their wearers from particulates, including wet particulates. Many of them have check valves that make them useless for protecting other people from the wearer. We don't yet know how much protection they provide against SARS-CoV-2 infection, because we don't know how essential saliva droplets are to contagion, but they probably provide some.

Although there are different kinds of N95 masks, the most common kind weighs a few grams; this is not uncomfortable.

Have you worn an N95 for any particular amount of time? Honest question. Because Uou refer to a few grams as “not uncomfortable.”

I find N95 face masks insufferably hot and muggy, with their “few grams” hanging off my nose and ears eventually very annoying. I don’t know if any hc workers that find N95s tolerable for very long.

I've spent a summer in +30°C heat doing demolition and foam insulation in a house that had been through a fire. I had to wear a heavy half face cartridge respirator the whole time due to both the toxins from the fire, and the toxins from the foam insulation.

I wouldn't say that was fun. But it was tolerable. A N95 mask is fine by comparison - not much worse than a surgical mask.

That’s funny, because I wear the cartridge respirator outside of work for some hobbyist reno stuff I do, and find it much more tolerable than the N95. To each their own, I suppose.
