A bit pricey for non medical grade, comfortable
These feel well made and build seems similar to the medical grade KF94/N95's. For the price, I wish it was medical grade. It's hard to test or judge filtration ability with these masks. What I can comment on is that they're comfortable. They do sit far enough from your nose and mouth to allow comfortable breathing. It's not laborious to breathe through and even wearing these for hours was not straining my ears. The nose fit and around the mouth seems to provide a decent seal.
