The hot sale oxygen concentrator uses air to produce oxygen, so will the indoor oxygen become less and less?

　　Even the presence of a hot-sale oxygen generator in an enclosed space will not reduce the oxygen in the space, because the oxygen generator does not consume oxygen, it just separates it.

　　We take in very little oxygen (5%-10%) when we breathe, and most of the oxygen is returned to the room through our breath. Therefore, the existence of a hot-selling oxygen concentrator is not much different from our direct breathing indoors. Of course, even so, we still recommend opening windows for ventilation frequently to ensure indoor air circulation.

　　The hot sale oxygen concentrator emits nitrogen, so will the nitrogen it excludes affect people indoors?

　　Air is originally 78% nitrogen and 21% oxygen and 1% carbon dioxide and other gases. The nitrogen discharged by the hot sale oxygen concentrator is mixed with air and the oxygen that people do not absorb, and it becomes air. The oxygen generator does not produce and consume any gas, so the existence of the hot sale oxygen concentrator will not affect the air.

　　In an absolutely sealed space, turn on a hot-selling oxygen concentrator, no matter how long it takes, the content of oxygen and nitrogen in the air will not change.
