To purchase an Oxygen Concentrator you must have a Doctor’s prescription of recommendation. If you cannot get one easily then I have an ND on my team who can give you a health consultation over the phone and provide you a prescription.
The above concentrator (Airsep Intensity 10) is the most versatile brand and model, as it can also be used in pressurized oxygen situations like with use in a hyperbaric chamber. It also has one of the highest LPM (litres per minute) oxygen flow which is essential for when a person is using it paired with exercise EWOT and we are taking many more breaths and deeper breaths per minute. In terms of price point this brand and model is lowest and also in terms of quality this was one of the first companies on the market to offer professional commercial grade concentrators to residential users. Notice the Airsep has a warranty that is 3 times as long as other brands. Be sure to get this brand if you are going to be using it heavily in a commercial setting.
I have showed the other two competing brands below which in the last 7 years have almost matched and with some features surpassed the Airsep model I talk about however they charge a lot more for what I don’t think are features that I consider essential and functional for EWOT and Hyperbaric usage.
The most important thing is that the Oxygen Concentrator you are planning to buy should carry some international approvals like FDA, CE & ISO.
The second most important thing is that the specifications should suit your requirement. The parameters you can consider to compare different models of different brands can be flow rate, battery backup, alarms (especially low purity of Oxygen), weight, power consumption and portability.
I’ve learned that when it comes to decibel ratings you can’t really go by what the manufacturer or company says. Sometimes I wonder where they get their readings from! Unfortunately the only way to really assess loudness is in person measuring it and also just listening to it for yourself. I have done this with all the highest air flow brands and models. I also put it in an adjacent room and try to get measurements and assess how it sounds with room partition. This can be important to note if you are considering using it in a home or apartment with other people living with you.

The AirSep Newlife Intensity 10 delivers 10 LPM of high pressure and high flow oxygen. It was designed to meet high flow requirements that can also provide essential outlet pressure to drive respiratory accessories like medical nebulizers, venti-masks and volume jet nebulizers. The Intensity delivers high pressure that can power long oxygen tubing runs.It is a home concentrator that weighs 58 pounds and features audible alarms that alert you of high and low pressure, low oxygen and power failure. The Intensity operates at 20 psig and is the only concentrator out today that combines high pressure oxygen with maximum high flow in a power friendly unit.The AirSep NewLife Intensity 10 is a unique home oxygen concentrator, because it doesn’t just deliver a high level of pure oxygen. It can also run a nebulizer, such as those used by asthmatic patients in hospitals, and can deliver air at a pressure of 20 psig, which is twice as much as most oxygen concentrators on the market today. The NewLife Intensity 10 is for people who need all of these features, and want to access them in the comfort of their own homes.As its name suggests, the NewLife Intensity 10 delivers up to 10 LPM of continuous flow oxygen, at an average purity of 93%.

The NewLife Intensity 10 also features the essential alarms needed to keep you safe and to ensure that there are no delays in your oxygen therapy. An alarm will sound in the case of low concentration levels, power failure, high temperature and high and low pressure. As long as there are no alarms for anything, the NewLife Intensity 10 works quietly so that you won’t be disturbed while you are receiving your oxygen therapy.
With all of these features and power, you might expect the NewLife Intensity 10 to be extremely heavy and large – this isn’t the case at all. It weighs in at 58 lbs, is 27.5 inches tall and 16.5 inches wide. It should be able to fit in next to your bed or living room chair without taking up too much room. You will even be able to roll it under a table to get keep it out of the way and safe in your home.
Product Description Brand #2
Review conclusion: The biggest drawback with this machine is Operating altitude range is up to 1,368 feet (417m) which is strikingly low as compared to all other oxygen concentrator in market which have range of approx 10,000 feet (3,048m). It’s really quite ridiculous when you think about it as a lot of people live at higher altitudes.
Another thing I noticed was the humidifier is screwed directly on the Oxygen outlet of the machine. Some people have reported difficulty in fixing the humidifier. Very easy to clean once fixed.
As far as sound I found this brand to be loudest compared to the other two.
The Respironics Millennium M10 is the highest performing and most reliable high flow 10 LPM oxygen machine available. It reduces the delivery costs associated with 5+ LPM oxygen users. The M10 reduces the cost of providing oxygen at higher liter flow. It also has fewer parts than any other concentrator on the market. Fewer parts, combined with greater reliability, reduce your expenditures on unnecessary accessories. The Millennium M10 is the highest performing and most reliable high flow 10 LPM oxygen machine available.
