Interesting, I just checked the Xcaper website for the first time since I last posted about this, and you can find their consumer mask kit sold on Home Shopping Network! Actually, it looks like a great deal--$35 instead of $55. For a mask that actually filters CO, I'm actually very tempted to jump and buy some of these at such low prices. Compare that to the $75+ many of us paid to by our EVACU8's.
