Photos of Snorkels With Purge Valves

Purge valves make snorkels easy to clear of water. These photos show snorkels with purge valves, from left to right: Cressi Gamma, ScubaPro Laguna 2, Aqualung Impulse Dry Flex, and Mares Breezer Purge.

Purge valves are incorporated into snorkels to make it easy for a diver to clear water that enters the tube. A purge valve is a one-way valve at the bottom of the snorkel. If water enters the snorkel, the diver simply exhales and the water is easily forced out through the valve. Snorkels with purge valves are exponentially easier to clear than snorkels that do not have purge valves, and are a rapidly becoming the industry standard.
