Before covid, I would be sick with a cold or flu for a total of about two weeks every year. That means I spent 4% of my time sick; one out of every 25 days. Since covid appeared, I’ve been wearing an N95 in crowded indoor areas whenever I reasonably can. (Obviously I can’t if I’m eating something.) My main goal initially was to protect my elderly relatives, but during the last four years I have not gotten sick even once, except from my elderly relatives who didn’t wear masks, got sick, and then infected me when I was caring for them.
Why isn’t everyone wearing N95s? Sure, it’s uncomfortable, but being sick is much more uncomfortable. And then there’s the fact that wearing an N95 protects other people and not just the wearer…
They’re frequently called “disposable respirators”. I do also own the non-disposable sort with rubber seals and screw-in filters, which is what I would wear if I worked in a hospital covid ward, but for everyday wear the disposable ones seem like a better compromise between efficacy and comfort.
I worked for a company that sold them and I’ve literally never heard them called that. That must be a regional thing.
“Disposable respirator” sounds like it was named by the same person who came up with “flushable wipes.”
