What’s a Portable Oxygen Concentrator?

A portable oxygen concentrator machine(O2 concentrator) is a medical device that delivers almost pure oxygen through the nose by tubes to those who require it. It brings in ambient air from the room it is placed, compresses the oxygen in a filter called a Sieve Bed. The Sieve Bed essentially holds on to the Nitrogen in the air and passes the Oxygen to the patient. The Nitrogen will be released back into the room. The air supply will never run out as long as the machine has a reliable power source, either by plugging it into the wall or using the supplied battery.

Why is an oxygen concentrator machine so expensive?

O2 concentrators dispense oxygen in almost exactly the same way that oxygen tanks do, delivering oxygen directly to the patient via the same nasal cannula or oxygen masks. However, where oxygen tanks contain a fixed amount of pressurized oxygen Concentrator collects oxygen from the surrounding air, concentrates it, and then delivers it to the patient, removing the need for replacement or refilling. O2 concentrators are also available in multiple styles, offering larger models for use at home or in the hospital as well as more compact models perfect for traveling and moving out and about.


Instead of the limited amount of pressurized oxygen used by oxygen tanks, the oxygen Concentrator use a filtering system to take ambient air in from around the patient, compress and modify it to medical-grade standards, and then deliver it to the patient. These devices are available in both larger home-style models and smaller portable models that are more ideal for traveling and moving around on the go.


For people who need long-term oxygen therapy, the daily cost of solutions like a quality reconditioned Portable Oxygen Concentrator is much lower in comparison to other options such as Oxygen Bars, Oxygen Tanks, or cans of oxygen. At less than $2 a day for a Portable Concentrator, the annual cost of an equally portable solution to breathing difficulties averages at around $700.

Advantage and disadvantage of oxygen concentrator machine


Unlimited oxygen. The ability of the oxygen Concentrator to continuously draw in and treat air ensures that, unlike oxygen tanks, the concentrator will never run out of oxygen. This is frequently noted by customers as being one of the best features of the oxygen concentrator.


Lightweight. Because they do not rely on pressurized oxygen Concentrator does not require a dense metal tank. This means that they are notably lighter and more portable than most oxygen tanks. In fact, many oxygen concentrators, such as the Invacare Platinum Portable Oxygen Concentrator, are designed to be carried in a backpack or side bag for ultimate convenience.


Multiple fictions and design. Oxygen concentrators are available in a wide selection of sizes, models, and styles, each designed to perfectly accommodate a specific user base. While oxygen tanks are large all the same, Concentrator provides a greater variety of choices to ensure you get exactly what you need.


No maintenance cost. While oxygen tanks frequently need to be refilled or replaced, oxygen Concentrator uses ambient air and therefore don’t require the long-term maintenance costs that tanks do. All of your o2 concentrator’s costs will pay in your initial purchase.



Batteries required. Because they do not use pressurized oxygen within a tank, the Oxygen Concentrator must rely on battery or electric power to perform their air filtering and oxygen flow. As is the case with any battery-powered device, the available charge in the battery must be considered. If the battery isn’t charged, it will eventually run out of power and the concentrator will shut down until charged again, which could be dangerous for someone who needs their oxygen at all times.


Noisy. Oxygen Concentrator collects oxygen from the air and then filter and compress it for the user. This process can often be noisy, due to the various components at work, and this is the most common complaint that concentrator users have. Many newer concentrator models have been designed to reduce this noise to barely noticeable levels, but there is often still some amount of sound associated with their operation.


Expensive. Because of the complex mechanisms at work, oxygen Concentrator is often quite expensive up-front. While this cost is a single purchase unlike that of oxygen tanks, many people may not be able to afford the high price tag all in one chunk even though it saves money in the long run.

How long does the oxygen concentrator machine Last?

Generally speaking, it is not a problem to use a household oxygen concentrator for 3-5 years, but it depends on your daily maintenance and daily use time. The warranty period of the household oxygen concentrator is 2 years warranty.


  1. When purchasing an oxygen concentrator, you first need to consider your purpose, whether it is for human use or daily health care, to decide whether to buy a household oxygen concentrator or a medical oxygen concentrator. If you need the whole family to use it, you can directly buy a home oxygen generator, which can be used by the elderly and young people for daily oxygen therapy.
  2. Secondly, the service life of the oxygen generator should be considered, mainly the molecular sieve. The molecular sieves of the oxygen generator are divided into imported and domestic molecular sieves. Generally, imported molecular sieves are hundreds of yuan more expensive than domestic ones. Imported household oxygen generators are mainly because the life span of imported molecular sieves is longer than that of domestic ones. Generally, the life of an imported molecular sieve is 18,000 hours, and the life of a domestic molecular sieve is 12,000 hours. Moreover, the performance of the imported molecular sieve is more stable, the oxygen concentration is higher, and the oxygen output is more stable. So in general, imported molecular sieves are more economical.
