I may be off base, but I seem to remember a couple of years ago a need to replace my mask. I had snapped one of the plastic parts, and it was only a couple of months old. Insurance only covers a new mask every 6 months, so I had gone in and found a replacement on a reputable website. I tried to place the order, and got a pop up about where to mail the prescription. I was blown away. It was not like this was a medication or that insurance was paying for it. I was just surprised. It was a good thing that I'm a pack rat and had saved my last 3 masks. I jerry-rigged them to make a working mask for 4 months until I could get a new one.
