What Sets Us Apart

Small, Light & Portable

It is up to 15 times lighter than stationary oxygen concentrators at just 4.4 pounds, and 9.9 pounds with all contents, and can be easy to carry with a backpack. The device fits easily into a car’s trunk, so you can take it with you wherever you go. Take along with it to join outdoor activities like golfing and hiking without being a burden. 

* This weight may not be suitable for the elderly over 80 years old, as this weight is still not light enough for them, so please consider carefully before placing order. (The exterior battery features high capacity, therefore a bit heavy.)

Pulse Flow Oxygen Delivery

The machine delivers oxygen in pulse mode which delivers oxygen only when it detects the inhalation signals and stops when exhalation. In this way, it can save power and significantly extend battery life. It doesn’t support continuous flow oxygen delivery.

Supported by Dual-Battery System

The concentrator has a built-in battery(lasts about 2 hours) and an exterior battery(lasts about 2 hours). So no more worrying about running out of battery outdoors or traveling.

Output Oxygen Flow Up To 3L

The max flow of the portable oxygen concentrator equals 3 Liter per minute at setting 3, and the oxygen concentration can be up to 93±3% at 1L, which is good for patients with respiratory diseases. The higher flow, the lower concentration will be, which is good for those without respiratory diseases like fatigue relief, sleep improvement, endurance enhancement etc. Not all groups are suitable for high concentrations of oxygen therapy.

Enjoy Forest Air In-home
