EverGo™ Portable Oxygen Concentrator
How does the EverGo™ portable concentrator work (produce oxygen)?

The Respironics EverGo portable concentrator separates oxygen from room air and delivers it through a single lumen cannula. Room air contains approximately 21 percent oxygen and 79 percent nitrogen. By passing the air through a series of molecular, bacterial and dust filters, EverGo removes nitrogen and stores nearly pure (therapeutic) oxygen.

Can I use the EverGo portable concentrator when I travel?

EverGo is ideal for people who enjoy traveling and rely upon oxygen therapy. EverGo operates from a wall outlet (AC power), an automobile charger (DC power), or its internal rechargeable batteries, two lithium ion batteries similar to the type used in laptop computers. The device has been cleared for air travel by the FAA. Because airline policies for traveling with an oxygen concentrator vary, you need to check with your airline before flying with EverGo.
