Check out the smallest of the small in our selection of pulse dose portable oxygen concentrators, which are the AirSep Focus, AirSep Freestyle, Freestyle 5, Inogen One G3 and Lifechoice ActiveOx. These portable oxygen concentrators are all around or under 5 pounds, even with their batteries. If you need pulse dose oxygen in a smaller dose, between the settings of 1 and 3, these small and lightweight models are ideal. With the Inogen One G3, you can choose between the 8 cell or 16 cell batteries, which have an average duration of 4 hours and 8 hours respectively.

On a slightly larger scale, we carry pulse dose models that can maintain higher settings, with great battery life to match. The Respironics EverGo is one of our most popular models, both for its long battery duration and wider range of pulse dose settings (from 1 to 6 in 0.5 increments). The Invacare XPO2 has can deliver up to 900 ml of pulse dose oxygen per minute, is only a little over 7 pounds with the battery and was designed to be carried comfortably with its sleek carry bag.

The Inogen G2 is also a little over 7 pounds with its battery, and is one of the quietest models, with your choice of the 12 cell or 24 cell battery. The robust Oxus delivers pulse dose oxygen between the settings of 1 and 5, weighs just under 10 pounds and comes with a lightweight and easy to maneuver carry cart.
