I don't know if you like or have tried KF94-style masks -- after a lot of trial and error, I've found they work best with my face shape and are comfortable enough for several hours of wear. The brand I use is KN Flax and they have a few different colors here: https://knflax.com/collections/merged-adults -- they're lightweight but seem pretty protective and I've used this brand for a couple years now with no issue (aka no covid -- or anything else!), knock wood. I work retail, so nobody's breathing or coughing directly on my face or anything, but I do interact with a lot of humans.

When I was using KN95s, though, I often bought some from VIDA (https://shopvida.com/collections/adult-masks) -- they use several different manufacturers, I believe, so the feel and style would change from time to time, which was kind of annoying, but I know they vet their manufacturers pretty well so I still felt okay about them protection-wise. Later, I found a few of those same masks for a bit cheaper than VIDA on Planet Halo Health (https://www.planethalohealth.com/), which also seems like a pretty reputable mask source to me, with several different brands and styles available.
