1-7 Liter Adjustabe Household Oxygen Concentrator Machine for Home Use, Up to 93% Oxygen Purity Air Flow Continouse Generator

I bought this for my mother in law to use at church. She is in poor health, but still wants to be of service to others. I thought this would be more convenient than trying to transport tanks of oxygen. It's small and very portable. It's lightweight, but still very sturdy. It's just as good as her full sized one that she uses at home. Her oxygen levels are doing great and she feels much better now. She's so happy to have her energy levels back to normal. It does make a bit of noise, but it's similar to her full sized oxygen concentrator.

I searched many different websites for replacement filters and could not find them. So it worked for a while. Remember this is not medical grade equipment. After 4 months it was done.

Immediately after taking it out of the packaging, I was able to put it together in a couple of minutes. The user handbook was easy to understand, and I did not have any feelings of being overwhelmed by any of the technical aspects. After I had finished connecting everything, I changed the flow rate, which can be anywhere from one to seven liters per minute, so that it would meet my precise specifications. Because it enables me to tailor the oxygen flow to my degree of comfort and the requirements of the activity I am doing, I believe that having this adjustable range is a wonderful feature.

It works great

The inlet air filters Alarm to be replaced every 240 hours. Where can these be obtained and what is the part number ?Who actually makes this machine ? I have contacted the name on the back, and they say it is not their unit !

What, I like about this is the quality looks very nice. the sound is very low decimals and delivery was very quick.Very good looking oxygen concentrator. I am very happy with it.

The size is not what i expected, the noise is loud and don't like it. Poor quality and not worth it. Don't Buy it.

At first this unit was great but then it started making like a grinding noise it's hard to sleep with. Tried to contact seller and they blew it off so now I have a unit I can't use unless I want to hear what sounds like ball bearings grinding. And I paid alot for this unit. I'm not happy
