Oxygen concentrator generators on the market are mainly divided into health care and medical equipment. Although the oxygen production principles of the two are roughly the same, there are many brands, uneven quality, and very different functions.

　　 With the increasing prevalence of heart, lung, and brain diseases, household oxygen concentrator generators have become a necessity for many families. So how do we choose a household oxygen concentrator generator?

　　 1. If you do home oxygen therapy, the oxygen concentration must reach 90% or more, so long-term oxygen therapy can really play the role of auxiliary oxygen therapy. It can be detected by the instrument or the oxygen monitoring device that comes with the oxygen concentrator generator. The oxygen concentration real-time display function of some brands of oxygen concentrators: real-time display monitors the changes of oxygen concentration, and the visual LCD screen allows users to know whether the oxygen concentration is always above 90%.

　　2. The core component of oxygen concentrator generator-molecular sieve, the quality of molecular sieve directly determines the level of oxygen production concentration, the better the molecular sieve performance, the higher and stable the oxygen production concentration of continuous oxygen supply.

       3. Choose an oxygen concentrator generatorwith an unchangeable cumulative timing function to provide an objective basis for future daily maintenance.

　　4. Warming oxygen function: equipped with headset heater, the 5-15℃ oxygen is heated to 20-35℃ and then the oxygen is inhaled to prevent the patient from inhaling cold air and causing irritation to the respiratory tract. At the same time, the built-in ambient temperature sensor and heating sensor ensure the safety of the oxygen concentrator generator product. There are three fault alarms at the same time: pressure alarm, temperature alarm, and power failure alarm three alarm functions to ensure the user's safe oxygen inhalation.

　　5. The oxygen concentrator generator has low noise: long-term operation of the oxygen concentrator generator may affect the normal work and rest of myself and others. Therefore, it is necessary to use a low-noise oxygen concentrator generator. The noise level is preferably less than 45 decibels.

　　6. The compressor displacement is large enough (3.8-4.2m3/h), otherwise it will be worn out for a long time and the efficiency will decrease.

　　7. Choose home oxygen concentrators that have been tested for a long time and have passed ISO international and CE European quality system certification. At present, there are many brands of oxygen concentrators on the market.
