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.
