We are excited to offer the newest addition to the ActivOx portable oxygen family -- the highly anticipated
LifeChoice ActivOx 4 L portable oxygen concentrator. The LifeChoice ActivOx Portable Oxygen Concentrator is finally available in a model that can provide up to 4 pulse settings. Until now, the popular Lifechoice ActivOx was only available in a unit offering 1-3 liters per minute. Now, oxygen therapy patients, who require up to 4 LPM, can enjoy the freedom and peace of mind in a more robust portable oxygen machine without having to compromise on weight.

Identical in dimensions to the other ActivOx models; the Activox 4L portable oxygen machine weighs just 5 pounds, and has truly raised the bar with its combination of size, weight, power, ease of use and high flow oxygen capabilities.

Like the previous model in the ActivOx family, the Activox 4L features the same unique Auto Mode and Pulse Wave Technologies that work together to deliver oxygen equal with the user's normal breath rate and breathing pattern. This intuitive technology results in a quiet, gentle delivery of oxygen to help minimize the uncomfortable side effects such as dry nose and sinus irritations that are often associated with other types of pulse-dose delivery oxygen concentrators.

The ActivOX 4L Portable Oxygen Concentrator with patented Auto Mode Technology and Pulse Wave Delivery is capable of providing a source of oxygen 24 hours a day, 7 days a week.   

  • Auto-Mode is an inherent feature that automatically detects changes in your breathing patterns and adjusts the unit's breath detector sensitivity accordingly to provide oxygen during all levels of activity during the day and throughout the night while at rest.  
  • The Activox 4L oxygen concentrator utilizes Pulse Wave delivery technology which is triggered on demand by the user during inhalation. The PULSE-WAVE Breath Detection Symbol will flash as you breathe. This is confirmation the device is delivering a dose of oxygen with each inhaled breath. If you stop breathing through the nasal cannula (mouth breathing), the 4L unit will begin delivering doses of oxygen automatically and will continue to automatically provide doses of oxygen until normal breathing resumes. 

Not only can the the Activox 4L deliver up to 4 liters per minute of oxygen but this device offers users a "best in class internal battery runtime" -- up to 10.25 hours of re-chargeable internal battery runtime. For oxygen users requiring additional battery life there is an optional powerful, lightweight, external battery available which provides up to 4.75 hours of supplemental battery runtime.  

The Activox 4L is FAA-approved for in-flight use on all domestic and international commercial airlines, making it the ideal portable oxygen travel system for long trips and vacations. The New ActivOx 4 L features a simple 'push button'  and easy to read display which simplifies operating your ActivOx and helps to reduce troubleshooting calls. The ActivOx 4 L comes standard with a custom carrying case allowing you to; carry the device with a briefcase handle, wear over the shoulder, or configure to be worn as a backpack. Your ActivOx 4 L system comes with both a AC (wall) Charger and DC (Vehicle) Charger to recharge your Activox's batteries.

  1. Oxygen Concentrator

    Posted by Thomas Trimble on 29th Jul 2018

    This unit seems to have some issues. First it has a noticeable vibration when running. Since it is leaning against your body you can feel it. The strap is cheap for a unit this expensive. It should have a good shoulder pad to keep it from sliding off and cushion the strap since you carry this for long periods of time. The external battery is a bad design. It is hard to plug in and store in the case. It should be a plug in unit that adds to the concentrator body. Generally the controls are good and the unit does seem to do the job

  2. Freedom From The Tanks

    Posted by Unknown on 28th Jul 2018

    This is a nice machine. Although It's a bit louder than I expected. The Inogen G4, is a lot more quiet. The long life of the battery is awesome. Even though I have only had it a few weeks, I think it is a great buy.

  3. Work very well and quietly

    Posted by Floyd Montgomery on 17th Jul 2018

    Although it feels a little heaver that I expected, I can tell the difference from the bottled oxygen and the mechanical regulator on 2L.pulse. This is much better. Over all, i am pleased with the this concentrator, and the battery life allows me to fly where I want to go.

  4. What An Awesome Gift !

    Posted by Heidi C H. on 31st May 2018

    This unit was requested because it allows me to return to many of the activities I love and had to give up, including hiking and outdoor activities. The ActivOx is lightweight, relatively quiet and comes with it's own carrying case. I love the fact that it has an internal battery as well as an additional external one. All in all, this unit is such a blessing. After a year and a half of lugging big bulky tanks around, the ActivOx is a God send. Thank you for this Product and for giving patients in need of supplemental oxygen a more convenient and effective way to obtain it.

  5. LOVE! My Activox 4L Portable Concentrator

    Posted by P Randall on 28th May 2018

    Look no further this unit may be a little heavy than some others that are on the market. However this unit has the best battery running time also you can keep the battery charged in your car when driving. The external battery is a great addition to have. This Company & Jeff are great to deal with. Would buy from again.

  6. Outstanding!

    Posted by Massy on 17th May 2018

    LifeChoice ACTIVOX 4 L Portable Oxygen Concentrator:

    Great value! Not heavy or cumbersome. Allows plenty of flexibility. Battery (w/backup) is adequate for a full day outing - even in pulse 4 mode. Has changed my life for the better!

    Outstanding service from this company. They are very responsive and find solutions for your unique situation. Product pricing is more than competitive. This should be your first and only stop for any oxygen needs you may have!

  7. Life choice is the best!

  8. Excitedly Pleased !

    Posted by Roy Knight on 4th Mar 2018

    I have used this machine for only 10 days now and I'm pleased to say it's a KEEPER. What I really like about is that you can set it on the floor and it does not tip over, it's comfortable too from the shoulder. Only down feature is the shoulder pad which could use a bit more padding.. Best of all is the looooong lasting batteries, five hours plus on first charge,

  9. I like it!

    Posted by Ray on 6th Jan 2018

    I have pulmanary fibrosis and doing hard things tired me very quickly. I now find I do much better!!! this morning I did .5 miles on the treadmill set at 1.5 incline and 2.2 mph. This was a huge improvement .
    Still felt good. I am 94 years old :-)

  10. Stop looking

    Posted by Karen Merlino on 24th Oct 2017

    Not only is this unit perfect for those of us who want freedom, this company is one of the best company I have ever done business with. The unit is great. I was told that it would be loud. I am on a 2 and it is not loud at all. Battery last a long time compared to other units. External option. Plugs for home and car. A really great unit. I have been around many portable compressors lately and I must say this is the best around. Stop looking.
