Lightweight Small Stature Big Performance Portable Oxygen Concentrator

With a weight less than five pounds, the AirSep Freestyle 3 is a light weight portable oxygen concentrator that allows for you to get out and explore during oxygen therapy without having to lug around similar bulky and heavier machines. The Freestyle 3 can be powered by a rechargeable battery, a power supply for in home use, and through a cars DC power adapter making it an excellent machine for on the go oxygen users. An air belt can be purchased as an additional power source to help lengthen the life of the Freestyle oxygen concentrator for longer day trips.

Multiple power options

The rechargeable battery will last upwards of three and a half hours on the first level setting, allowing for you to adventure for hours at a time during oxygen use. The AirSep oxygen concentrator can also run off of a cars DC power adapter for longer road trips. During at home use, the Freestyle has a power supply that will run consistently. An optional air belt can be purchased which will extend the battery life and allow you to go on all day trips with consistent oxygen. On setting one you can expect three and a half hours of battery power with an additional six and a half hours from the air belt allowing for ten hours of consistent oxygen during use. Higher settings will result in a shorter battery life, with a combined six hours on setting two and five hours on setting three if you have both the battery and air belt.
