Scuba Gear is unnecessary... the only necessities in life are shelter, food, water and air... everything else is a luxury in this life... And the bio filter is one luxury that is worth the money to me as is helps me get one of the necessities... water, with my air.
And as far as people talking about failure points... I have been using and selling them for years... sold hundreds upon hundreds of them. So far the failure and return rate is Zero... None... Nada.
I'm not going to spend thousands to take a trip half way around the world and have the last 15 minutes of each dive be uncomfortable because of dry mouth - lungs, etc. If I'm spending that much time and money to enjoy myself... I plan on enjoying myself... even the simple things like breathing.
Interesting. I notice that mdb (Apollo) has a similar view.
Also, please forgive my ignorance, but i do not see how the necessities you mentioned (shelter, food water, and air) extrapolate to "...water with my air."
