The First Dry Snorkel with FRESH-AIR gets even better.

Here’s how it works: As you must know by now, the exchange of CO2 (exhale) for O2 (inhale) occurs in billions of alveoli cells in the bronchial tubes & lungs, but not in the 4-6 inches from the trachea to the mouth hole—the stretch known as dead air space. A primitive snorkel triples dead air space, so you re-breathe the same air, which is like wearing the same sox or not changing your skivvies. Burning lungs with a heavy heart & head afflict the snorkeler breathing too much CO2. Do you really feel like sighing in an elevator?
