A group of manufacturers are selling canned oxygen. It comes in flavors and it's a bit like bottled water: a thing that you can get for free but might pay for anyway. But why breathe flavorless, odorless oxygen; when you can have the Mountain Breeze, or Mint Escape. They rae are creating all sorts of flavors and essences to add to their oxygen products including lemon, eucalyptus, cherry, mint, and a host of others. The market has proven that ideas such as this - built on a foundation of being pure, fresh, and clean - can be a huge success.
