Explanations and Features: * The ultra-quiet Everflow includes all the cool features of the original Everflow Center oxygen center in a quieter model. The typical 43 dB only Ever Flow is one of the quietest capacitors on the market. The compact form factor, advanced engine, low power usage and durable lightweight construction make it easy, convenient and extremely popular! * Provides free energy and hassles * Everflow is designed from the ground up to provide consistent, hassle-free performance and reduce the total costs of oxygen therapy. Its advanced engine delivers 5 liters per minute of ever flow oxygen, while using less electricity and producing less heat than most other stationary oxygen concentrators; so everflow costs are less expensive to operate, saving you money every day. * Ergonomic design and build quality The comfortable flow meter and metal canal connector mean that ever flow is less prone to accidental fracture, while the comfortable inner storage cabinet allows you to store additional tubes. * Easy-to-use Everflow Moisturizer Bottle Holder (bubble humidifier not included), with velcro fastening tape, compatible with all standard bubble moisturizers. * It provides free, hassle-free connection to the humidifier and the oxygen tube at the top of the unit as it is more convenient. At Home At Home * Use of oxygen therapy has been traditionally restricted, requiring frequent bottle changes or noisy capacitors; but with Everflow you can finally be free of hungry capacitors or annoying bottles. Volume is one of the biggest factors that separate Ever Flow from its competitor. At a cost of just 31 lbs, Everfluow is small, lightweight and unnoticeable, so it fits easily into the home without disturbing everyday life, and is easy to transport wherever needed. * Easy to use and easy to maintain * The Everflow interface panel features a simple on / off switch and flow meter rotation for easy control without confusing additions. Three lamps * indicator (green, yellow, red) and audible alarms help ensure the capacitor is working properly. * Design trouble-free and energy-saving motor for cars * Comfortable features and quality construction * Comfortable feel in your home! * Easy to use with minimal maintenance * Safety first! * Available oxygen ratio indicator

Clarifications and features: * The iGo portable oxygen system is the ideal solution for maintaining an active lifestyle. The portable, lightweight 3-liter oxygen system offers two methods of operation - continuous flow or pulse dosing. The reliability and safety of pulse conduction has demonstrated the effectiveness of oxygen delivery in clinical tests as well as through independent tests by doctors and respiratory therapists. * IGo comes with battery, AC power adapter, mains power source, and DC power adapter. IGo can be moved using a wheeled carrying case for easy portability. * IGo includes a DeVilbiss oxygen sensor and service alerts to give peace of mind that iGo offers exactly what is needed. * Settings from 1 to 6 in pulse dose mode or from 1 to 3 liters per minute in continuous flow mode. * The built-in pulse oxygen preservation technology extends the time of use of the iGo portable oxygen system, providing greater mobility with improved comfort and increased efficiency. * Built in oxygen sensor to ensure accurate oxygen delivery and reduce periodic maintenance schedule. Increased battery capabilities - iGo is powered by a single battery that can last long at 5.4 hours when operating in setting number 1 in pulsed dose mode Audible power off alarms, low battery, low oxygen output, high flow / low flow, no detection Breathing in pulsed doses, high temperature, unit malfunction. * Can be used with 50 feet tube / cannula in continuous flow mode and 35ft cannula / cannula in pulse dosing mode. If the unit is running on AC power and the power is turned off, iGo will automatically switch to battery operation. * Three molded handles in the condenser body. * Easy access to the filter compartment. * No need for three-year maintenance.
