Oh, and my most recent purchase was these bad boys:

Last year I bought
these, which were OK but didn't have adjustable straps, so when they left gaps on either side I had to buy
band extenders to go around the back of my head and correct the problem. The ones I just bought are adjustable (although they fit me perfectly as is).
The other mistake I made last time was believing that they weren't reusable. As long as you air them out properly between uses, they should be fine. I bought a 10-pack so it will be weeks before I have to reuse an individual mask. Just store them somewhere where they're well ventilated (but where no one is touching them).
