Selection of oxygen generator:
First, when making oxygen, the maximum output oxygen concentration of oxygen generator must reach 90%.
Second, choose a low-noise oxygen generator, and the noise decibel should be controlled within 45 decibels. Too much noise will affect people's mood and sleep at night.
Thirdly, it is very important for the elderly with respiratory diseases and heart failure to choose the oxygen supply that can be uninterrupted for 24 hours to ensure the oxygen concentration.
Fourth, don't care too much about the price when choosing a home oxygen generator. Choose the brand of regular manufacturers, and don't be deceived because of small profits.
