Oxygen Concentrator-Health Expert 1-8L/min Portable Oxygen Machine with fogging function for Home Use

My son has serious allergies, and I heard that this oxygen concentrator in combination with an air purifier would help. I placed it in his room and I’m sorry to say it had the opposite effect. He coughed and hacked all night long the first night, but I figured maybe he was just getting accustomed to it. Nope - the second and third nights were just as bad if not worse. :( It also was not as easy to move around as advertised and the sound kept him awake, too. For the price point, I’m just going to return it. Super disappointed that it didn’t work.

Its oxygen supply effect is not as shown in the figure. It not only meets my daily needs, but my husband suffers from respiratory tract disease. The doctor suggested that I take oxygen regularly, which is why I bought this machine. However, when using it, it may not completely meet my daily needs, and sometimes there may be a disconnection of oxygen, which almost makes me go to the hospital. Additionally, there is a problem of poor contact with the charging interface, which greatly affects my use. Do not purchase!!!!

I read the instructions carefully, followed everything they had to say, cleaned the pipes and plugged in the power. The machine was turned on, but no oxygen was produced. No air flowed out of the machine. No air bubbles in the tank. Very disappointed with this purchase. Return the product as soon as possible!

It cannot be carried by an elderly person or be considered a portable oxygen source. Because it is bulky and not light, the power cord is very short. You will need an extension cord. The cannula smells awful and the quality is not good.

The flow is adjustable. Any questions can be answered in time. The After-sales service is very good.
