Portable oxygen generator

I’m wondering if anyone knows what is the quietest portable oxygen generator that provides continuous flow at 2L. The home medical store has provided Oxlife Independence concentrator, but it seems noisier than the larger DeVilbiss one I use at home. Hard to sleep with it in a hotel room or stay with someone in their home. I only need it for sleeping.

  1. Hi , and thanks for your post and question - it's a good one! Generally speaking we do not make recommendations concerning commercial medical equipment. I am hopeful that others will chime in when they see your question and share their own experiences using 'quiet' oxygen concentrators in the home setting.
    In the meantime, I was able to do a basic search of the internet and found some information that addresses your concerns. I will say that what is noisy for one patient, may not be so for another. To remain objective, you may want to look for the sound level of the machine, usually reported in decibels, which will give a more practical assessment of the intensity of the sound generated by the concentrator.
    For your convenience, here is a link to the search i was able to do:
    I do hope you find this information is helpful for you.
    All the best,

    1. Testing of My Inogen Home.
      Inogen Home Decibels-Liter Flow Settings

      Level 1 40
      Level 2 40
      Level 3 41
      Level 4 43
      Level 5 44

      1. Sorry but I posted for the Home Concentrator instead of the Portable.
        The Inogen G5 oxygen concentrator has an operational noise level of 38dBA and a lifespan of about 5 years. Additionally, this oxygen concentrator lets you enjoy a restful sleep with the help of its low noise feature.

        1. Hi , and thanks for each of your posts. I am sure others in the community will appreciate you sharing the sound levels that accompany the use of your both your home concentrator as well as the portable unit. Generally speaking, the range in which your unit(s) function are considered to be acceptable and safe for adults. Naturally, what is loud for one person may not be so for another.
          For our members who are interested, I thought this article might provide some additional insight:,dBA%20can%20cause%20hearing%20loss.
