1. What is a nebulizer and nebulizer therapy?
Our 105W home oxygen concentrator comes with a built-in nebulizer. A nebulizer is a device that turns liquid medicine into a fine mist, which you can breathe in through a mask or mouthpiece. This allows the medicine to reach your lungs directly and work more quickly. Nebulizer therapy is often used for conditions like asthma or COPD, and it is safe and easy to use at home. With the 105W, you can enjoy both oxygen support and nebulizer therapy in one simple machine.2. What is the difference between continuous flow and pulsed flow?
A continuous flow oxygen concentrator means the oxygen generator can continuously supply oxygen. But pulse oxygen concentrators usually supply oxygen based on your breathing, because pulse oxygen concentrators usually have breathing sensors.3. Can I use 105W overnight?
Yes. The high-quality compressor in the 105W allows for continuous use up to 48 hours. It operates quietly, with a noise level as low as 45 dB, allowing you to sleep soundly while using it overnight.4. Is 105W heavy?

How does an oxygen concentrator work?
How does an oxygen concentrator work?
A portable oxygen concentrator is a device that separates oxygen from the air and allows you to breathe in the oxygen on an as-needed basis. Portable oxygen concentrators can run on both AC and DC power, and they can be charged by both. This battery charge allows it to bring in air, separate the oxygen from the rest of the air, and deliver it back into your lungs at whatever rate is appropriate for you. Some portable oxygen concentrators offer both continuous flows and pulse dose settings.
The home oxygen concentrator is a device that converts air into oxygen, allowing you to breathe easier. It runs on AC power and is only compatible with home or stationary models. The concentrator brings air through the inlet vent into the machine, where it passes through a filter that catches dust and other small foreign particles before going through an oxygen separation system. The oxygen is then released through the tube and cannula in the proper dosage.
