LifeChoice Activox 4L: No Tanks, No Hassles, No Boundaries!

Introducing the LifeChoice Activox 4L portable oxygen concentrator, this is the latest engineering genius from Inova Labs, the manufacturer that produces other elite units such as the LifeChoice Activox Pro and the lighter Activox Sport. The Activox 4L builds off of the incredible reliability and user friendliness that is found with other Activox units, except the Activox 4L is more advanced and is guaranteed to exceed any of your greatest expectations, leaving you to ask yourself why you haven't had a portable concentrator like this your whole treatment!

The LifeChoice Activox 4L delivers an extra pulse flow setting of 4, giving patients the opportunity to live the Activox lifestyle that were simply unable to use the pulse setting of 3 on previous Activox concentrators. The 4L also features an easy to read transflective display, so you can always be aware of what setting you are using, plus a battery gauge of the internal and external battery (sold sep.) is clearly displayed on the screen so you will always know the status of your battery(s).
