The oxygen concentrator should be used for at least 30 minutes each time it is turned on. Frequent use for a short period of time can cause the molecular sieve to become damp, as the oxygen source is air, which has a certain degree of humidity.

As a health equipment, when choosing a household oxygen concentrator, it is important to pay attention to the product's technology, liter selection, noise, and brand. At present, household oxygen concentrators on the market mainly rely on molecular sieves and oxygen production technology, with molecular sieve technology being a relatively···

The alarm code for household oxygen concentrators is required by regulations. Low oxygen concentration alarms occur when the machine is not working properly. When the oxygen concentration is below 50%, an alarm will occur. E3 alarms are divided into machine working environment reasons and hardware reasons.

Users who are using oxygen concentrators for the first time should not worry about E2 fault codes. E2 fault codes are mandatory alarm functions required by national laws and regulations, usually generated by low oxygen flow.

The medical oxygen concentrator must be a 3-liter machine. When the new machine leaves the factory, the oxygen concentration must be greater than or equal to 90%. After use, when the oxygen concentration is lower than 82%, the molecular sieve must be replaced. In addition, the country requires medic
