I wrote about these when they first came out and have been wearing them since then, with good results. It looks like Amazon isn’t selling them directly anymore (only via third-party sellers) but Northern Safety has them for $0.59 each, and sometimes for $0.19 each on sale. (The brand is different but it’s the same mask.)
