There are a number of K or KN 95 masks on the market. The KN is the US standard, and though it can be argued that the K95 might be better. In any case, it is I choose this one. It is lightweight. The metal strip across your nose keeps it in place, and and MORE IMPORTANTLY, keeps your glasses from fogging up. A big problem! This mask doesn't irritate me like all the others did. I kept wondering if I could use my K95 construction mask. But for a VERY long time - no guidance. This works well, is supported by the government, and keeps me able to see, and is the most comfortable of all I bought..... Mari
