What should I pay attention to when using an oxygen concentrator?
Avoid placing the oxygen concentrator near open flames or using it while smoking. Regularly check oxygen concentration and device alarms to ensure safe and effective use. For those with chronic conditions, monitor blood oxygen levels continuously during use.
What’s the difference between continuous flow and pulse flow?
Pulse flow detects your inhalation and delivers oxygen only when you breathe in, conserving power. Continuous flow provides a steady oxygen stream regardless of your breathing cycle. Pulse flow is typically used in portable devices for longer usage time.
Is the noise level of the concentrator loud?
Most oxygen concentrators produce between 30–60 dB of noise—about the same as a quiet conversation. Our devices are designed to be as quiet as possible for home and outdoor comfort.
When will the alarm light activate?
The alarm activates under these common conditions:
Do I need a prescription to purchase an oxygen concentrator?
No. GenixAir oxygen concentrators are available without a prescription.
Can I use the oxygen concentrator on an airplane?
Our devices are not FAA-approved. We recommend using them for land excursions instead.
How does an oxygen concentrator work?
Oxygen concentrators draw in air, filter out nitrogen, and deliver concentrated oxygen. Portable models operate on AC/DC power and battery, while home models require AC power only.
Are the batteries rechargeable?
Yes, the batteries can be charged using an AC adapter or a DC car charger. Charging time depends on the model and battery age, typically ranging from 4 to 5 hours.
What is the atomization function?
The atomization function allows targeted respiratory therapy by delivering fine particles that are easily absorbed and cause minimal irritation to the airways.
Does the oxygen concentrator support in-vehicle use?
Yes. Our portable models support AC (100–240V) and DC (12–16.8V) input, making them suitable for global and vehicle use.
Can the machine run continuously?
Yes, home models support 24/7 operation, even during sleep. Some portable models include auto-stop every 4 hours to prevent overheating.
Do I need to add water?
Some models include a humidification feature. Please follow product-specific guidelines. Others, like water-free models, do not require water at all.
How do I replace the battery?
Our portable units feature replaceable batteries for extended use. Follow the instructions in the user manual for safe replacement.
How to choose a suitable oxygen concentrator?
We offer Portable, Home, and Lightweight Series. Refer to our product guide or consult support to match your lifestyle and medical needs.
What’s the difference between portable and home units?
Portable units are compact and battery-powered for travel use. Home units offer higher oxygen flow but are larger and stationary.
