The ultra quiet EverFlo Q includes all of the great features of the original EverFlo Oxygen Concentrator in a quieter model. At just 43 decibels typical EverFlo Q is one of the quietest concentrators on the market. Its small form factor, advanced motor, low power usage, and lightweight, durable construction make it easy, convenient, and very popular!

Ever Flo Q is designed from the ground up to deliver consistent trouble-free performance and reduce overall oxygen therapy costs. Its advanced motor provides 5 LPM of Continuous Flow Oxygen, while using less electricity and producing less heat, than most other stationary oxygen concentrators; so EverFlo Q costs less to run saving you money every day.


A recessed flow meter and metal cannula connector mean EverFlo Q is less prone to accidental breakage; while a convenient internal storage cabinet lets you store away extra tubing. EverFlo Q's easy-to-use humidifier bottle holder (bubble humidifier not included), with velcro holding strap, is compatible with all standard bubble humidifiers. And it provides a trouble free connection for the humidifier and oxygen tubing at the top of the unit where it's most convenient.


Using oxygen therapy has traditionally been restrictive, requiring frequent bottle changes or heavy, noisy concentrators; but with the EverFlo Q you can finally be free of power hungry concentrators or inconvenient bottles. One of the biggest factors that separate the EverFlow from its competition is size. At just 31 pounds EverFlo Q is small, light and inconspicuous so it fits easily into the home without disturbing daily life, and it's easy to transport wherever it's needed.


EverFlo Q's interface panel has a simple on/off switch and rotating Flow Meter Knob for easy control without confusing extras. Three indicator lights (green, yellow, red) and audible alarms help ensure your concentrator is working properly. As an extra safety precaution, choose the optional OPI (Oxygen Percentage Indicator). With OPI a light on the front of the unit will turn orange and sound an alarm if oxygen levels ever deviate from acceptable purity levels.

    My wife's insurance recently replaced her concentrator with a loud monster of a unit and it spurred me to start looking to buy one. Ratings for the units showed the Respironics EverFlo to be among the quietest at 45 db and it was the lightest at 31 lbs. No Insurance Medical proved to be the best price on the net. I placed the order, supplied an RX and it was promptly shipped.
    I couldn't be more pleased with the concentrator. It's so quiet I found myself checking to see if it was really running at first. We use the unit in our motor home and it's not a struggle to carry it out the the home, nor to coexist with the unit in a very small home.
