I chose the EverGo mainly based on its battery life. I have not been disappointed in my choice. The EverGo is easy to learn to use, reasonably compact and easy to transport thanks to the lightweight cart.1/9/2013 7:28 AMWas this review helpful? Yes / No (0/0)
Prior to purchasing the EverGo I rented both the Inogen and the Evergo.1/9/2013 7:28 AM
Both concentrators use pulse technology hence would not be suitable for someone requiring continuous flow oxygen. Also, keep in mind that the setting of 2 doesn't necessary equate to 2 liters continuous flow, that just means at that setting you'll receive a certain dose of oxygen (at a setting of 2 the Inogen delivers 15 ml and the EverGo delivers 23 ml). The Inogen has settings from 1-5; the EverGo from 1-6.
The Inogen has two advantages over the EverGo. First, it is quieter (40dBa vs 47(units made before 4/08) or 43(units made after 4/08) dBa). Second, it has a remote conserver unit so you can use the Inogen as a stationary concentrator when you are at "home" with up to 100 feet of tubing. In every other respect I think the EverGo has the advantage over the Inogen:
* Battery life: At 20 breaths a minute, setting of 2 the Inogen lasts 3 hours; EverGo 8 hours (this is using two batteries. If you want to lessen the weight by 1.5 pounds you can remove one battery and still have 4 hours).
* Breath detection: Inogen didn't always detect my breath, I felt I had to remind myself to be more forceful in taking a breath; this was not a problem with the EverGo.
* Maximum oxygen production: The EverGo gave me more oxygen than the Inogen when I had it at the highest setting . EverGo delivers up to 1050 ml/min; Inogen delivers 750ml/min).
* When I out-breathed the machines: Inogen would give pulses on alternating breaths (very disconcerting when you are SOB!); EverGo would alert you that you had max'd the machine out but you would get a pulse of oxygen on each breath albeit a smaller pulse than the setting normally would provide.
* Cart: I liked the way the EverGo attaches to the cart better, more secure.
* Elevation: the EverGo is rated to 8,000 feet. I'm not sure what the Inogen is rated for.
Overall I felt my oxygen need was fulfilled much better with the EverGo than with the Inogen.Was this review helpful? Yes / No (2/0)

My recent purchase of a Respironics EverGo portable O2 concentrator has provided me with a huge increase in my quality of life. With the four batteries I have, the unit weighs about 17 pounds, but I am able to leave home for over 17 hours (at my flow rate of between 2 and 3)---imagine doing that hauling around O2 bottles! The small lightweight cart that the unit comes with is a breeze to pull--unlike my O2 bottle cart. If for any reason I can't use the cart, I usually remove the extra batteries from the case, and just carry the normal unit, saving me about seven pounds. In short: I've broken the bottle habit and will never go back!1/9/2013 7:28 AMWas this review helpful? Yes / No (0/0)
