The Otoo Inhaler uses scent technology to create the perception of flavor when inhaling oxygen. Your sense of smell plays a huge role in taste—up to 80% of what you “taste” comes from scent. When you inhale through the Otoo nozzle, the aromatic, food-grade scent molecules activate receptors in your nose, creating the experience of a flavored inhalation, even though the oxygen itself remains pure.
No. You are only inhaling pure oxygen – the scent is simply perceived through your olfactory senses, just like how you smell food before eating it.
The aroma inside the nozzle is designed to last for months with regular use. Over time, the scent will gradually fade, but the experience will remain enjoyable. To extend its lifespan, store the inhaler in a cool, dry place when not in use.
Increases oxygen intake – Helps with mental focus, recovery, and overall well-being.
Creates a refreshing flavor experience – Makes inhaling pure oxygen more enjoyable.
Encourages better breathing – The pleasant aroma may help encourage deep, mindful breaths.
Zero calories, zero sugar, no chemicals – Unlike energy drinks or boosted oxygen products that contain additives, Otoo is 100% pure.
Many users report feeling refreshed and recharged after using the Otoo Inhaler. Oxygen is a key component of energy production in the body, and inhaling pure oxygen can support focus, recovery, and an overall sense of well-being.

1️⃣ Keep your Otoo cap & nozzle – they last for a long time.
2️⃣ Buy the Otoo Refill Kit – contains oxygen canisters only (cheaper than a new starter kit).
