To judge whether an oxygen concentrator is good or bad, it is important to look at the following points:
One look: whether the oxygen concentrator can run stably for a long period of time and whether the oxygen concentration is stable.
An oxygen machine that can run stably for a long time and has a stable oxygen concentration can not only guarantee that the oxygen absorber can continue to absorb oxygen and get a better oxygen absorption effect, but also show that it is a high-quality oxygen machine.
A good oxygen dispenser can run stably and continuously, and at the same time can ensure the stability of oxygen concentration. If the heat dissipation of the oxygen machine is not good, it will lead to the inability to continuous power, may also be able to continuous power but the long time the oxygen concentration is unstable, even after more than ten hours of power on the oxygen produced has been close to the air, the oxygen concentration is greatly reduced. So when choosing an oxygen machine, the first thing to pay attention to is the stability of the oxygen machine's operation and the stability of the oxygen concentration.
The second look: compressor performance
Compressor is one of the main components of the oxygen machine, a good compressor can be used continuously for a long time, good heat dissipation. DEDAKJ uses pure copper oil-free compressor, to ensure that 24 hours of continuous operation and the oxygen concentration is stable;
Third look: the sound of the oxygen machine
There are a lot of people who use oxygen machines to inhale oxygen. The reason for this is that there are a lot of people who use oxygen machines, and one of the main reasons for this is that they are too noisy. If it takes more than ten hours a day to inhale oxygen, the long-term noise will not only make the user uncomfortable, but also reduce the user's compliance, which will lead to the exclusion of oxygen inhalation, and the rest of the family will also be affected. So silence is also an important part of the choice.
If the old man just inhale oxygen health care, with DEDAKJ 1L, 2L oxygen concentrator can meet the daily oxygen demand, if it is used for long-term oxygen therapy, you should consider Deda's 3L, 5L high-flow oxygen concentrator, to protect the long-term long-term supply of oxygen more stable.
