You won't need to worry about disturbing anyone while you are using your portable oxygen concentrator in public, even if you are in a laid back restaurant or a movie theater. These models emit a pulse of oxygen that is as soft as a whisper, but is still strong enough to meet your medical needs. Just because they are quieter doesn't mean they are weaker.
We carry the quietest concentrators available out today at around only 38 decibels; about the same noise level as a library. They include the Inogen G5, Respironics EverFlo Q, Invacare Perfecto and Respironics SimplyGo. The Inogen G2 is the absolute quietest portable machine available; you can barely tell its running! This machine will deliver oxygen up to the setting of 5 on pulse and weighs 7 pounds with the 4 hour battery and weighs 8 pounds with the 8 hour battery.
