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…
I used to wear KN95s every day as a cashier during the height of the pandemic. It was noticeably more difficult to breathe through them, especially when I was working carts duty in the dead of winter. It also doesn’t help that masks like this would need to be replaced pretty frequently for maximum effect because the moisture of my breaths will make them wet after a period of time. I could feel the condensation building in my mask throughout my 4-6 hour shifts.
Oh yeah, and if you want your mask to work properly, don’t have a beard. Those will impair the filtration because air will get through your beard instead of your mask.
