Let customers speak for us
from 647 reviewsEverything feels well-engineered and reliable. Worth the money.

This oxygen concentrator exceeded my expectations in every way.

The handle makes a big difference. I move it around the house all the time.

The oxygen flow is steady, the unit is quiet, and setup was simple. Very happy.

Less than 2kg, fits in my backpack easily. Very portable.

My mother uses it daily. Simple controls and dependable oxygen.

Portable, lightweight, long battery life. Perfect for plane trips and road trips.

This concentrator gave me back a sense of independence. I can now rest and move around my house with ease.

The sound it makes is a soft, low hum, which is almost soothing. It's not jarring or annoying like other medical equipment can be.

I had a question about the warranty and their support team was quick to respond and very helpful. It's nice to know they stand behind the product.

I've tried two other brands. This is by far the best. The build quality is superior, the materials feel better, and it just performs better. This is the one to buy.

I was worried about a complicated setup. It was none of that. Plug in the battery, attach the cannula, and press power. It was running in under a minute. Perfect.

It's not an eyesore! It has a sleek, modern look that doesn't scream 'medical device.' I don't mind having it out in the open when company comes over.

This concentrator offers excellent value. It has all the features I need at a fraction of the cost of other models. I'm very satisfied with my purchase.

This isn't just a device; it's a lifeline to the outside world. It reduces my anxiety so much knowing I have reliable oxygen with me wherever I go. It's empowering.
