I've been buying the 3M 9211+ like the one in the first picture at Amazon US, but there are none available there now except some that look like the second picture, which I don't want. I'm traveling in a couple of weeks. Where do you all buy them?

Also, what's the difference between the two?

Edit: It’s been clarified here that the second picture is the old version of the mask, which was updated a couple of years ago. I checked 3M’s Amazon listing again and noticed that, even though their pics show the old version, all the customer review pics show the new version, so I ordered from Amazon
