One of the main things many people consider when purchasing an oxygen concentrator, is how much noise it will make. You don't want to bother anyone or have your oxygen concentrator bother you while you are trying to do things like watch TV, read a book, have a conversation with someone, or sleep if you need to use your oxygen concentrator while you sleep.
For this reason, we've rounded up user reviews of the extraordinarily quiet stationary and portable oxygen concentrators on the market right now. Naturally, many of the bigger stationary oxygen concentrators will be louder than the smaller ones, but the larger ones offer a higher dose of oxygen that some people require.
You should never let the noise level bother if you need a higher dose of oxygen – getting the among you need is much more important than the noise level. These are the quietest oxygen concentrators in their size categories and dosage ranges.
