5L Medical Oxygen Concentrator Generator 93% Concentration Household 24 Hours Continuous Oxygen Machine for People and Pet 220V

Provide oxygen with a concentration of 93%±3% for 24h. Smart remote control It allows you to set the device remotely (including backlight, operation time and oxygen flow rate), making oxygen inhalation easier. Thanks to the stable and high-efficiency lithium molecular sieve, high adsorption efficiency, stable performance and sustainable high-concentration oxygen output can be achieved. Efficiently filter out impurities in the air to make the generated oxygen cleaner. Timed oxygen can be set up to 4 hours, and it will automatically shut down after the time is up.
