Is this a continuous flow oxygen concentrator?

No, our portable concentrators use a smart pulse flow system that detects your breath and delivers oxygen precisely when you inhale.

Is the oxygen clean and pure?

Yes, our portable oxygen concentrators deliver 85-90% pure oxygen, drawn directly from the surrounding air. The advanced filtration and purification process ensures you receive clean, high-quality oxygen with every breath.

How long does the battery last?

A single charge runs up to 5 hours, depending on your level. The battery is replaceable, so a spare keeps you going longer.

How can I power the device?

You can run it on home AC power, a car DC socket, or its battery. It also works while plugged in and charging.

How heavy is it to carry?

It weighs about 3 lbs, light enough for a shoulder strap. The compact build fits errands, travel, and time around the house.
