AirSep Focus Portable Oxygen Concentrator


It’s not an exaggeration to say that Airsep Focus is the smallest and lightest portable oxygen concentrator you will find in the oxygen industry. Weighing less than 2 pounds and measuring 5 inches wide and 6 inches tall, Airsep Focus is undoubtedly a huge deal in such a small package.

The Airsep Focus unit can discreetly deliver supplemental oxygen to users without sacrificing technological features to increase efficiency. Despite its small size and dimension, you will quickly realize that Airsep Focus is as reliable, efficient, and functional as other bigger and heavier POC in the market.

This device has several hours of battery life — making it ideal for long-range travels and high-altitude hikes. It can push to 3.5 hours at pulse setting 2. Its micro batteries can easily last up to 1.5 hours each, providing you with long hours of high oxygen concentration.

Additionally, it has multiple charging options for your ultimate convenience! Are you hitting the road to satisfy your wanderlust? You can use a DC power supply to charge your batteries and ensure an uninterrupted oxygen flow.

If you’re waiting for battery replacements, you can always operate without a battery with a universal AC/DC power supply. Ensure the device is set near an outlet, and you are good to go.

To make it even better, this unit is a lightweight innovation with superior technology — providing medical-grade supplemental oxygen at 2 LPM pulse on demand! All that for a fraction of the size of most units in the industry.

Honestly, with such amazing features and benefits, it’s only fair to classify the Airsep Focus concentrator as a major breakthrough in portable supplemental oxygen technology.
