At 31 pounds, the Respironics EverFlo Q is one of the lightest home oxygen concentrators on the market. It comes with 4 caster wheels so you can easily maneuver it around your house—from the living room to watch a movie, then back to your bedroom for sleep. Standing 23" H x 15" W x 9.5" D, you'll have no problems finding a place for it in any room. Whether your dogs get riled up or your grandkids come over, you won't have to worry about your concentrator getting in the way.

Operating your Respironics EverFlo Q is as simple as flipping a switch and turning a knob. The EverFlo Q is equipped with a 110v power cord for any wall outlet. Once plugged in, simply flip the switch on top and turn the knob to your required flow rate. If you use a humidifier, the EverFlo Q has a built-in humidifier holder—a recessed area on the back with a velcro strap to keep your humidifier bottle securely in place.

Respironics designed the EverFlo Q to keep required maintenance to a minimum. The only required maintenance is cleaning your concentrator with a damp cloth and mild soap, and replacing your filter every year or so—a 5-minute process. The flow meter and cannula inlet were designed to prevent breakage, saving you from unnecessary repairs. Backed by a 3-year warranty from one of the biggest manufacturers in the industry, the EverFlo Q is an oxygen user's dream.
