The problem with Easybreath is that:

Really sorry @TheSnapLounge @hal813 : we won't be able to sell it in the USA for 2014.

There are separate paths for inhaled and exhaled air I see, but also some dead space in front of the mouth. That volume of air goes back in... just like the air in an ordinary snorkel when breathed two-way. Can't tell from the pictures if that's really a problem... but still worth noting.

Hmm, interesting approach; start a thread, and never check back ... :headscratch:

Maybe you would be better off using a DPV instead of swimming. Rig it to float and add an O2 bottle if you have a need for more oxygen rather then more air. Maybe dive a 30 cu/ft bail out bottle with 100% O2 so you could switch back and forth from the snorkel to the bottle when you need more oxygen then you can get from the air.
