Quietest Portable Oxygen Concentrators

Woman with Inogen One G4 at Grocery StoreIf you are new to oxygen therapy and oxygen concentrators, you probably have a lot of questions about the experience of living with an oxygen concentrator machine. Wondering about the impact of an oxygen concentrator on your daily life is understandable, and it is often a large part of what drives people to choose portable oxygen concentrators. Among the questions people may have is often “Which is the most quiet portable oxygen concentrator?” So why does the noise level matter? Let’s take a look at why people might be concerned about noise with their portable oxygen concentrator, and take a look at some of the most quiet portable oxygen concentrators available. 

Why Sound Level Matters for Portable Oxygen Concentrators

Portable oxygen concentrators are machines created to convert the air around you into pure, medical grade oxygen for oxygen therapy. This can be a noisy process, and many oxygen concentrators are quite loud, which can impact your quality of life. Generally, portable oxygen concentrators nowadays can be as loud as 50dBA, which is about the same sound level as a large office, a large home appliance or a conversation at home.[1][2] None of these seem particularly loud… until you consider trying to sleep, carry on your own conversation or concentrate on a book with them right next to you. The fact is, carrying a noisy machine around with you is not only inconvenient, but it is also irritating. Moreover, the sound of the device may not only be frustrating to you, but it may cause loved ones irritation if they have to live with it, too. Even when the noise is coming from a machine you rely on for your supplemental oxygen, that amount of noise gets tiresome after a while. For this reason, many people look for the most quiet portable oxygen concentrator they can find. Thankfully, as it turns out, portable oxygen concentrators do not need to be noisy to be effective. 

Inogen Portable Oxygen Concentrators Are Quiet and Effective

Imagine trying to sleep next to your refrigerator or underneath a large electrical transformer.[1] Sounds miserable, right? If you think so, you are not alone, which is why so many oxygen therapy patients are motivated to find the most quiet portable oxygen concentrator they can. For many people, 50dBA simply is not quiet enough, and it is hard to blame them. Thankfully, Inogen has designed some of the most quiet portable oxygen concentrator units on the market today. In fact, all three of the Inogen One models come in at or below 40dBA. So, what does that sound like? 

The Inogen One G4, our smallest portable oxygen concentrator, is about the size of a pound bag of coffee and comes in at exactly 40dBA. That is about the same as the sound level inside a library or in a quiet residential area.[2] The Inogen One G3 is even quieter at 39dBA, while our newest model, the Inogen One G5, is the most quiet portable oxygen concentrator we offer at just 38dBA. Customers say they “love this quiet little machine” and the freedom and portability that comes with it. 

But freedom does not only come from the small size of our Inogen One products, though it certainly helps a great deal. Freedom also comes from the ability to live life as normally as possible, without having to yell over the sound of your oxygen concentrator or feel self conscious at the movie theater or at a play. With an Inogen One Portable Oxygen Concentrator, you can enjoy living your life as loud or as quiet as you want to be, without feeling drowned out by your own oxygen therapy. 

What to Do If Your Portable Oxygen Concentrator Is Suddenly Loud

Inogen One Portable Oxygen Concentrators are blissfully quiet, and once you start using one, you will become accustomed to what little sound they make. And that is precisely how they were designed—to improve your life and accompany you, without getting in your way. 

So, what should you do if your portable oxygen concentrator is suddenly louder than it should be? When your Inogen One is functioning properly, you will hear the slight hum of the compressor, the small click of the concentrator switching back and forth between the two columns that pull the oxygen out of the room’s air and the soft whoosh of the remaining air being purged from the column. This is all very quiet, and should always sound the same when everything is working as it should. If you notice that your Inogen One Portable Oxygen Concentrator is suddenly louder than usual, it is likely that your unit needs a little maintenance. First, make sure your tubing is properly connected to the nozzle fitting and double check that your flow setting is correct. Next, try cleaning the particle filter to ensure that it is not clogged with dust, dirt or hair, as a clogged filter will cause the compressor to have to work harder than it should, which can cause a louder hum. If that does not solve the problem, it is a good idea to call one of our oxygen specialists at 1-877-466-4364 to find out what you should do next. 

Keep in mind that all of our Inogen One models have a number of alerts and alarms to notify you of any issues with the unit, the battery or the functionality of your Inogen One. Some of those alarms have optional audible alerts, so if you hear any beeping, check the alert display. If you cannot remember what the display alert indicates, check your manual for more information. High priority alerts will continue to beep until the issue is addressed. 

Choosing the Most Quiet Portable Oxygen Concentrator

Each portable oxygen concentrator customer has differing priorities when it comes to the oxygen delivery unit they choose. Some people need the smallest unit possible for maximum portability, while others need a unit that can accommodate a number of different flow settings over the course of the day. However, for almost every person looking for a new portable oxygen concentrator, the sound level is important. A noisy unit is extremely intrusive and difficult to live with and, beyond that, it is a constant and loud reminder of your need for oxygen. 

At Inogen, we believe that oxygen therapy should improve your life and integrate into your daily activities as seamlessly as possible, which is why our oxygen concentrators are all among the most quiet portable oxygen concentrators on the market today. We design our products to improve your freedom, mobility and independence, and that includes allowing you to do the things you love, whether that is attending worship services or spending the day on the golf course. Your portable oxygen concentrator should never get in the way of a quiet conversation with a good friend, or the joy of reading a book on the lawn. Our Inogen One Portable Oxygen Concentrators are so quiet, you will quickly forget they are even there. Try any of our Inogen One models and discover how quiet and convenient your oxygen therapy can be. Contact us for more information and start breathing better today. Oxygen. Anytime. Anywhere.
