If you are prepared to pressurize it to a liquid,
A normal breath of air draws in about 100ml of oxygen. If you don't purify & recycle it:
To get more oxygen in a smaller space
What is your goal?
Just to clarify, are you saying a normal breath of normal air (ie: with an o2 content around 20%), will draw in 100 ml of o2?

Turning to the haze outside my window I started thinking, 'Wouldn't THAT be nice!'
How much does a rebreather cartridge cost and how long does it last?
