The FreeStyle 5 is one of the lightest portable oxygen concentrators to offer a pulse flow setting up to 5. Measuring in at just 6.6" W x 4.4" D x 10.7" H, it takes up minimal space providing you with the freedom to receive your prescribed amount of oxygen while still attending your favorite social outings such as book club, gardening club, or pulmonary rehab, without being weighed down.

The newly redesigned AirSep FreeStyle 5 features an entirely revamped battery system that uses external batteries only, keeping the unit as light as possible and making battery changes quick and simple. The front-loading battery is easily accessible, and the carrying case includes a side pocket for an extra battery. With the 2-bay desktop charger, you can charge two external batteries simultaneously. Expected battery life varies by setting: up to 4.25 hours on setting 1, 2.5 hours on setting 2, 2.0 hours on setting 3, 1.75 hours on setting 4, and 1.25 hours on setting 5.

Easily go from place to place with the trendy, inconspicuous carrying case featuring a convenient padded shoulder strap and a side pocket for an extra battery. An optional harness system connects to the carrying bag so you can wear the machine like a backpack for completely hands-free operation. The large, easy-to-read control panel on top ensures you can always confirm you are at the proper flow rate. Power your device anywhere with the included AC power supply, DC power supply for your vehicle, or lithium ion batteries.
