The Airsep Focus is an extremely lightweight portable concentrator and doesn’t require refilling it with oxygen. The unit weighs less than 2 pounds and is currently the lightest and smallest oxygen concentrator out today. The AirSep Focus is well known for being the smallest and most comfortable to wear portable oxygen concentrator on the market. How is the name relevant to this oxygen concentrator? You could look at it this way – you can focus on living an active and healthy lifestyle, after your oxygen needs are met by such a small and easy to carry portable oxygen concentrator. Despite its small size, you will find that the Focus has the same great battery life as larger portable oxygen concentrators, and is just as dependable and tough.

If you have a small portable oxygen concentrator, it should definitely have batteries that continue to give you the kind of freedom you need. The two micro batteries that come with your AirSep Focus will last for up to 3 hours (1.5 hours for each one). These are powerful lithium ion batteries that you can recharge with the AC/DC power supply when you are sitting still. To charge them back to 100% from 0% takes around 4 hours total.

If you need more time to be completely mobile, such as when you are doing some long distance traveling, you can use the supplemental AirSep Airbelt battery pack. This small battery pack is worn around your waist and can be plugged into the Focus for an added battery life of as much as 3.5 hours. This comes in handy if you want to travel by air, and your airline requires that you have much more than what your 2 micro batteries can give you. If you want to spend a day out of the house with friends without having to stop after 3 hours and charge your batteries, the Airbelt is ideal for you.

Air travel is already possible with the AirSep Focus, because it is approved by the Federal Aviation Administration for use on a passanger airplane. Just think of how easy it would be to take the Focus with you on a flight, because of how small and light it is. 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 receiveing oxygen therapy, since the carry bag and strap that come with your Focus just look like another other small hand bag.

If you purchase an AirSep Focus, you will also get a free nasal cannula, 2 micro batteries and the AC/DC power cord needed to charge the batteries, along with a universal power supply, a carry bag and shoulder strap. Your Focus is also covered under a 3 year warranty, and the batteries and accessories will be covered under warranty for 1 year.
