Philips Respironics EverFlo Q Oxygen Concentrator without OPI - Certified Pre-Owned

*Certified Pre-Owned* Main Features Lightweight and easy to transport at 31 pounds Compact, ergonomic design take up less space Amazingly Quiet Operation at just 40 decibels Uses less power and produces less heat Minimal maintenance. Internal filter change about every 2 years Description The EverFlo Home Oxygen Concentrator from Philips Respironics and Right Fit is lightweight, quiet, and efficient and it uses less power consumption than others of its kind. OPI models incorporate an Oxygen Percentage Indicator (OPI) as an additional safety measure. The OPI utilizes a front-facing light that will change to orange and emit an alarm in the event of any deviation from the acceptable purity levels of oxygen. This device is lightweight and compact and its unique design looks less like a medical machine so that it blends in with the furniture around it. It requires low maintenance, plus it needs less electricity and produces less heat. A recessed flow meter reduces the risk of accidental breakage and the metal cannula that it uses is more durable and less likely to break than other types. The concentrator features a platform that fits all styles of humidifier bottles and includes a simple velcro closure. The Oxygen Percentage Indicator (OPI) option ultrasonically measures oxygen output as a purity indication.
