The Aura is, as other people have said in previous threads, the gold standard of N95 masks. I've been wearing them solely for the last 6 months or so, and they are great! They rarely fog my glasses, they are very comfortable, I'm not in any hurry to take them off when I'm done, especially if it's cold out. The only downside is the straps: they both go behind your head, one high and one low. They take a bit to get used to, but you can't put them on with a hat on. But the plus is that they are very comfortable for the long term. Sometimes, with glasses, I have to take the glasses off to get the mask off. The ones with the blue straps, the straps seem to deteriorate quickly if left in the sun, but I've only had a couple where the straps broke. You can get them small quantity on ebay, and ebay seems to police the sellers, for around $2 each. You can also buy them direct from 3M for $1 in quantity 440, or at least you were able to 6 months ago when we last looked.
