The Respironics EverFlo Q is a compact home oxygen concentrator that comes in a neutral blue color. The EverFlo Q is just 23 inches tall, 15 inches wide and 9.5 inches deep and takes up less floor space than most stationary oxygen systems available on the market. The EverFlo Q was designed to look less like a medical device than many other oxygen machines. Its small size allows you to position it near you in your home.

The EverFlo Q features a molded handle at the top of the unit and four sturdy casters at the base for easy maneuverability throughout your home. Respironics developed this home oxygen system with durability and lower maintenance costs in mind. The lightweight blue casing makes the EverFlo Q an extremely durable oxygen concentrator. Furthermore, the machine features a durable metal cannula connector that is less likely to break than many other cannula connectors on the market. The EverFlo Q's flow meter is recessed into the hard plastic cover of the machine to reduce the risk of accidental breakage. A humidifier adapter on the humidifier bottle platform fits all bottle sizes.

The control panel on the EverFlo Q features an On/Off switch and the easy to read display has three LED indicators and an audible alarm to notify you of any issues with the machine or your oxygen concentration levels.

At 31 pounds, the Respironics EverFlo Q is lightweight enough to easily be rolled from room to room in your home on its sturdy casters. The unobtrusive design goes beyond the machine's compact size and maneuverability: At a sound level of just 40 decibels, the EverFlo Q runs quietly in the background while you visit with company. 40 db is between a light whisper and a normal conversation. The EverFlo Q is so quiet that many patients have reported that they and their partners have no trouble sleeping in the same room as their concentrator.

Oxygen Delivery:

The Respironics EverFlo Q produces concentrated oxygen from room air. The oxygen from the air is concentrated using a molecular sieve and a pressure swing adsorption process.

The Respironics EverFlo Q is capable of delivering anywhere from 0.5 to 5.0 liters per minute of up to 93% pure oxygen, making it a great solution for a large variety of oxygen therapy needs. In fact, the EverFlo Q delivers continuous flow oxygen which allows for use with CPAP/Bilevel therapy patients.

Safety is of paramount importance at Respironics, so the EverFlo Q's pressure swing adsorption technology helps to maintain ideal oxygen levels. Additionally, built-in alarms sound when the built in oxygen analyzer detects oxygen purity below 88%.

Starting Cost:

The Respironics EverFlo Q fulfills the clinical features that home care providers want in an oxygen therapy system in a compact and quiet shell. The EverFlo Q is an affordable solution for oxygen dependent patients and has a unique set of features to help lower the ongoing costs of providing oxygen therapy to patients.

Many home oxygen concentrators require frequent or expensive maintenance, but the EverFlo Q was designed to minimize those costs. For example, the overall design of the EverFlo Q, discussed above, aims to minimize accidental breakage of the cannula connector and flow meter. The filters in the EverFlo Q do not require patient filter changes, and home provider filter changes are only necessary every two years.

Furthermore, the Respironics EverFlo Q uses only 350 watts of power, less than conventional home oxygen concentrators. As a result, it also produces less heat than many other options on the market. This results in lower energy costs to run the EverFlo Q and increased comfort for you in your home.

The EverFlo Q arrives at your home with everything you need for setup. The concentrator features:
• Humidifier Bottle Mounting Strap
• Sturdy Metal Oxygen Outlet Port
• Recessed flow meter
