Yeah those are the ones I got. They are fine. Note they have rubber bands rather than elastic. I've had trouble in the past with the bands breaking, so I thought maybe these would break even more easily. But I haven't had trouble.

If the rubber band breaks it's usually at the very end, so you can fix the mask by prying out the staple that holds in that end of the band, and using an office stapler to reconnect the end of the band. This is a slightly time consuming procedure so you'll want to carry spare masks with you if you go somewhere with exposure. Then fix any broken ones when you get home.
