I got them because I was going through Etanks at 1 every 2 days. And the large stationary tanks were $300 p/month around here. But, I made sure to ask and they said that they have the same 98 percent (roughly) purity of oxegyn. The problem stems from the time it takes to purify it. And my problem is that they gave me the wrong mask when I asked for the rebreather several months ago. Thanks for the input on that John and Gary.
