What are the selection criteria for a qualified household oxygen generator?

In recent years, with the increasing prevalence of heart and lung diseases, oxygen concentrators have become one of the must-haves for many chronically ill patients with family therapy. Especially for patients who need long-term oxygen therapy at home, using a home oxygen concentrator is not only convenient but also more economical. However, there are many brands and types of oxygen concentrators in the market, and consumers often don't know how to choose.

What are the selection criteria for a qualified household oxygen generator?


Today, combined with some common sense of oxygen concentrators, I will share with you how to buy a high-quality oxygen concentrator.

1. What is an oxygen generator?

We can generally understand the oxygen concentrator as a machine used to produce oxygen. Generally, oxygen concentrators can be divided into two types, one is health care type, and the other is medical type.

2. What are the functions of the oxygen generator?

In addition to being used for routine health care, the oxygen generator can also be used for auxiliary treatment: respiratory diseases, cardiovascular and cerebrovascular diseases, and chronic obstructive pulmonary diseases (chronic bronchitis, bronchial asthma, emphysema, pulmonary heart disease, etc.) oxygen therapy need. It can also relieve chest tightness, arrhythmia, memory loss, dizziness, etc. due to hypoxia.

3. What are the key points for choosing a household oxygen generator?

1. Pay attention to the oxygen production method

    At present, there are many kinds of oxygen generators in the market, so try to choose a molecular sieve oxygen generator with mature technology.

2. To meet the oxygen concentration specified by the state

The state stipulates that the oxygen concentration of the oxygen generator is 93%±3.

3. To meet medical needs

According to the maximum oxygen output of the oxygen generator, the oxygen generators in the market are generally divided into 1L, 2L, 3L, 5L, etc. Generally speaking, you can choose 1-2L for ordinary daily health care. If you suffer from chronic diseases, you need Choose 3L or more, which meets the medical oxygen production standard. For those suffering from cardiopulmonary functional diseases, an oxygen concentrator of more than 5L is needed.

4. Whether it can provide continuous support

    A good-quality medical oxygen generator supports uninterrupted oxygen supply 24 hours a day to meet the oxygen demand of users.

5. Whether it can adjust the amount of oxygen

The oxygen concentrator that can adjust the oxygen concentration has a wide range of applications. It is best to choose an oxygen concentrator that can display the real-time oxygen concentration, so that it is more comfortable to use.

6. Consider the convenience of operation

    Choose an oxygen generator with a large screen and large fonts, which is convenient for the elderly to use. If it comes with a voice broadcast function, the operation will be easier.

7. Consider the noise of the oxygen generator

The oxygen generator will produce sound during the oxygen production process. Choosing a good vibration isolation effect can reduce noise.

8. Choose a big brand

When buying an oxygen generator, it is recommended to choose a big brand with strong brand strength, good product quality, and good reputation, especially if the after-sales maintenance needs to be timely, and all aspects of the guarantee are guaranteed, it will be more assured to use.


When purchasing a household oxygen generator, you must choose it according to your actual needs. For simple health care, you can choose 1-2L. If it is used for auxiliary treatment, you must choose a medical grade above 3L. Pay attention to the key points above. In general, the larger the oxygen generator, the larger the scope of application. If possible, choose 5L as much as possible. For example, the Lepu Leyi oxygen generator is a 5L medical oxygen generator that implements national standards. It adopts a modular molecular sieve design. The oxygen generation rate is not only fast but also stable. It can ensure an oxygen concentration of more than 90%, and Continue to produce oxygen for 24 hours. It also has 0.1L visualized intelligent control to ensure accurate oxygen use. Large screen display, 12-level intelligent warning, convenient for the elderly to use.
