  1. Very portable 4 Star Review

    Posted by on 8th Oct 2014

    This machine is nice and small. Very portable. It will be used for daily activities. The only downfall is it's limitations for settings. Other than that, great LITTLE machine!

  2. Small 5 Star Review

    Posted by on 22nd May 2014

    I only use oxygen while I am active so the Focus sounded like the best and lightest option for me. Upon arrival, I was surprised to see how small it actually is. The pictures don't do it justice to it's size. Thank you for the guidance!

Magnifying the Focus on Oxygen Patient Mobility

AirSep Focus places the focus on oxygen patients’ convenience and comfort in the most lightweight innovation in oxygen portability that has ever been available. Noticeably lighter than any other portable oxygen concentrator, the new Focus fits in the palm of your hand.

The AirSep Focus Portable Oxygen Concentrator (POC) provides a solution to the most commonly-requested POC feature – smaller size and lighter weight. The Focus is a system an oxygen patient can feel good about carrying, by removing the burdon of extra weight.

The AirSep Focus is FAA approved for air travel, so it provides the utmost is travel advantages.

This mini-weight, portable oxygen concentrator makes its own oxygen on demand, providing a pulse flow up to Setting 2. The Focus is not only easy to carry, but also easy to understand. There are no confusing control-panel readings; just the information you need. All at your fingertips, with the flip of a switch. And the non-medical look ensures that you’ll stay as mobile and active as possible.

Multiple Power Options

The Focus is powered by a one-half pound micro-battery. These batteries provide power in a very small package that can easily be attached to one’s hip, on a belt, or even on the shoulder strap of the Focus unit.

Each battery provides a power display in 25% increments, enabling you to have an easy visual indicator of the battery charge. Each micro-battery powers the unit for 1.5 hours. Each Focus system is supplied with two (2) micro-batteries.

For even longer battery duration times, you can get the optional AirBelt battery belt pack. The AirBelt provides 4 hours of battery time and is easily worn around the waste.

The Focus can also be used with a universal power supply when connected to an electrical outlet or an automobile power outlet. The universal power supply will charge the battery at the same time.
