For high-altitude pilots, no element is more valuable than oxygen, not even gold or platinum. Aerox understands that which is why the company has invented the Oxysaver, an ultra-efficient nasal cannula that keeps you from wasting precious O2. The cannula captures your exhaled air in a reservoir and mixes it with the exact amount of oxygen you need to breathe. When paired with low-flow meters the Oxysaver can increase your canister life by up to 8 times over standard, continuous flow systems. This model of the Oxysaver features a pendant-style design with the reservoir positioned at chest level for ease of use with a standard aviation headset and boom mic. Quit wasting oxygen and fly longer in between refills with an Oxysaver.
