High Purity OxygenThe oxygen concentrator is made of molecular sieve imported from France, and the variable pressure adsorption method is used to obtain high purity oxygen at room temperature. It is manually adjustable from 2-9L and can reach a maximum oxygen concentration of 93% when adjusted to the number "2". Different people have different oxygen concentration needs and can adjust it to suit their situation. It is relatively small and can be easily lifted by the elderly. Low noise design Oxygen machine working noise is 45 decibels, using low noise design, noise reduction more thoroughly. After using the remote control to open the sleep mode, the tank light will go out, you can properly open the negative ion key, the negative ion concentration in the machine ≥ 8 million / CM³), which can make the air in your surroundings become good, improve the oxygen absorption rate and improve the quality of sleep. Long service lifeHigh life, strong performance, easy to operate, plug in fast oxygen production, six levels of filtration oxygen absorption more peace of mind. The water tank can be wetted oxygen, so that the throat will not dry. Wide range of applications (the elderly, pregnant women, sports people, brain overload, stress, children, etc. can be used), improve the quality of life, only good health, life will be good. The LED display will show sleep mode, negative ion status, cooling fan, timer time and cumulative time. 48 hours of continuous oxygen production, each press of the timer button is 15 minutes, the maximum time can be timed 180 minutes, the machine will automatically shut down when the time is up; work for one hour, the display will show "1", This gives you a better idea of your oxygen intake time.
