Oxygen Concentrator 5 liters

Flow rates: Up to 5 liters per minute Noise Level: Quiet —on average, 40 dBA Operates at elevation up to 8000 feet The lightest home concentrator, weighing just 18 pounds One of the most energy-efficient, lightest, and quietest oxygen concentrators on the market today is the Inogen At Home Stationary Oxygen Concentrator. It is half the weight of its counterparts, weighing in at around 18 pounds. Inogen At Home is an oxygen concentrator with a continuous flow rate of up to 5 liters per minute (LPM). Continuous flow oxygen concentrators employ a nasal cannula to supply a consistent stream of supplementary oxygen to the user's nasal passage. In addition to being extremely lightweight, the Inogen At Home is quiet, averaging roughly 40 dBA operating volume, or the volume of a quiet library. This home oxygen concentrator is also energy efficient, using the same amount of energy as a 100W light bulb on an oxygen flow setting of 2 LPM. It’s no surprise that Inogen oxygen concentrators are some of the most popular devices on the market.
