HOW TO USE – With the sleek O-Stick oxygen dispenser in hand, press the easy-pull lever with your thumb and release the flow of oxygen while you inhale through your mouth or nose. 3 to 5 breaths usually does the trick.

OH YEAH. – The pioneers of the industry, Oxygen Plus was founded in 2003 to create consumer-friendly and effective oxygen products. We established the best practices of recreational oxygen and we stand by our high-quality products that are made in a FDA-registered facility by our 30-Day Money Back Guarantee. Part of the healthy, active person’s everyday life, Oxygen Plus is a dependable energy and recovery tool for work, home and play – anytime you need a lift. Our oxygen canisters are designed, quality-controlled and filled in the U.S.A., and O+ canisters are 100% recyclable after use. Oxygen Plus is the only portable recreational oxygen filled in the U.S.A. in a FDA-registered facility. Oxygen Plus is designed for optimum convenience. The oxygen flows stronger with a new canister, and dispenses more slowly as you use it. The canister is completely empty when the oxygen flow stops while the actuating button is depressed. Each O+ oxygen product states “Best by 24 months from fill date” on the canister. The fill date is located on the bottom of each canister. While the gas of oxygen itself never expires, we added this "shelf life" or product lifespan timeframe to ensure you're completely satisfied with the value of your purchase well beyond the typical time you'd finish a canister. After 24 months, O+ products will still work and are safe to use if stored as directed, however a user may experience slightly fewer “breaths.” FYI, a canister that's been opened or used does not expire any faster than an unopened canister.
