Home oxygen concentrator is mainly used to facilitate people with hypoxia problems to absorb oxygen at home at any time, effectively improve hypoxia problems and help tissue metabolism maintain normal operation. As people pay more and more attention to health, home oxygen concentrators have been gradually popularized. Therefore, many people will have some small problems in the use of home oxygen concentrator. Here are some common situations to share the solutions.

Comon situation 1: there is smell in the air flow.

Some consumers responded that the oxygen from the newly bought home oxygen concentrator had a plastic smell. The oxygen from the oxygen concentrator is filtered by triple filtration, which is usually odorless. The plastic smell should come from oxygen absorption devices such as oxygen suction tube and humidification cup. The solution is also simple. Soak the connecting tube, oxygen absorption tube, humidification cup and other devices in vinegar solution. The solution is configured according to the ratio of vinegar and water 1:3. Soak for 3-5 minutes, and then wash with clean water and dry.

Common situation 2: there is ponding in the oxygen suction pipe.

There is water in the oxygen suction pipe. It is likely that the water level in the humidification cup exceeds the maximum warning line, and the air flow presses the blister into the gas transmission pipe. Generally, when using the household oxygen concentrator, the water in the humidification cup needs to be controlled, not too much or too little. If there is a scale on the humidification cup, the water level shall be controlled between the lowest water level line and the highest water level line as far as possible;

In addition, when it is cold, oxygen is absorbed. Because there is a temperature difference between inside and outside the pipe, the water vapor in the pipe will be condensed into water droplets. Clean up the accumulated water, and the oxygen suction tube can be reused when it is unobstructed.

Common situation 3: the machine makes a “bare” sound every few seconds.

The principle of home oxygen concentrator is to leave oxygen and separate nitrogen through the adsorption of molecular sieve, and the exhaust sound is the normal nitrogen exhaust sound, indicating that the machine operates well.

FAQ 4: after startup, the machine operates normally, but the oxygen flow is always small.

Check whether there is air leakage at the connection between humidification cup and oxygen suction pipe, check whether there is blockage in the pipe, appropriately increase the oxygen flow and see whether the air flow is restored. If it’s not, it’s not ruled out that it’s the problem of the oxygen concentrator itself. You can contact the after-sales service to solve it.

FAQ 5: after startup, there are bubbles in the humidification cup, but there is no oxygen from the oxygen suction tube.

In this case, the rubber plug of the humidification water tank is not plugged properly. Remove the humidification water tank and plug the rubber plug.
