The AirSep Focus is a very lightweight portable oxygen concentrator and doesn’t require refilling it with oxygen. It's the lightest and smallest oxygen concentrator, weighing less than 2 pounds. Your oxygen needs can be easily met by this small and easy to carry device, with great battery life and superior toughness.
It's also as quiet as they come, the puffs of air only as audible as a whisper. The people around you will hardly be aware that you are receiving oxygen therapy, since the carry bag and strap that come with your Focus just look like another other small hand bag.
The powerful lithium ion batteries that come with your AirSep Focus will last for up to a total of 3 hours. A full charge takes around 4 hours total. There is an optional supplemental AirSep Airbelt waist battery pack available that will add as much as 3.5 hours of service.
