Boost Oxygen: Portable Supplemental Oxygen Canisters

Boost Oxygen delivers 95% pure supplemental oxygen in a lightweight, portable canister you can carry in a gym bag, backpack, or pocket. It's an over-the-counter product — no prescription required — designed for healthy people who want a quick lift after exertion, at high altitude, or during travel. Athletes reach for it during aerobic recovery, hikers and skiers use it to cope with thinner mountain air, and older adults keep a can handy for that occasional pick-me-up.

Sizes are chosen to match how and where you'll use them. The Small 3-liter canister is genuinely pocket-sized for on-the-go moments, the Medium 5-liter suits daily gym or travel use, and the Large 10-liter offers the most breaths per can for regular users and shared household use. Each canister features an easy one-hand trigger and built-in mask, so a measured breath of oxygen is always ready without fumbling with valves or tubing.

Aroma is a personal choice, not just a scent. Natural is unflavored pure oxygen; Peppermint and Pink Grapefruit add a refreshing note; and Menthol-Eucalyptus (Breathe) gives a cooling, open-airway sensation many find useful during cold season or after a workout. All flavors deliver the same purity — the difference is entirely in the experience.

A common question: is this the same as medical oxygen? No. Boost Oxygen is a recreational supplement for healthy individuals and is not a treatment for any medical condition or a substitute for prescribed oxygen therapy. If you rely on continuous oxygen, explore our Oxygen Supplies & Parts, Oxygen & Aerosol Masks, and Oxygen Cylinder Accessories instead. For more everyday wellness picks, browse the full Boost lineup.
