When purchasing an oxygen generator, it mainly depends on the technology and quality of the oxygen generator, and whether it is suitable for users to use.

    For people who are slightly hypoxic and only used for health care purposes, there is no special demand for oxygen output and concentration, and a one-liter machine on the market can be used. For pathological hypoxia, it does not require daily For people who take 24-hour oxygen for health care, most of them use 2-liter machines. To carry out oxygen therapy and health care according to their own conditions, it is best to have the guidance of a professional doctor.

    People with serious pathological hypoxia need 24 hours a day to take care of oxygen. Such users have a low oxygen utilization rate, so they have special needs for oxygen concentration and flow. The specific use is mostly an oxygen generator that can produce oxygen continuously for 24 hours and has an oxygen concentration alarm. Therefore, it is generally dominated by machines with three liters or higher gas output and oxygen concentration. The choice of a home oxygen concentrator should be determined according to the user's situation, and cannot be selected blindly.

    For some people, the oxygen concentration of the oxygen generator must be greater than 90%, which can only be detected by the instrument or the oxygen monitoring device that comes with the machine. Choose an oxygen concentrator with an unalterable cumulative timing function to provide objective and accurate data for future long-term maintenance and service. Equipped with a cumulative timer is a mandatory requirement of international standards, and it is also a reflection of the quality of the product. The service life of the oxygen generator (oxygen generator) should be guaranteed for tens of thousands of hours. Oxygen generators with low noise should also be considered, and the noise level should preferably be less than 42 minutes, otherwise. it May affect the rest of myself and others, especially at night.
