Product Description

The Respironics EverFlo Q is a home oxygen concentrator that delivers up to 5 LPM of continuous flow oxygen in a quiet unit that weighs around 31 pounds. The design features of the EverFlo combine quiet operation, compact design and low maintenance into a single unit. It delivers around 90 to 96 percent of oxygen concentration with liter flows that range from 0.5 to 5.

The stylish, compact design allows it to fit easily into any room without being an eyesore. It also features 4 wheels on the bottom of the machine that make it easy to move around in any setting. At an operating noise level of 40 decibels, it is as quiet as most normal household appliances.

It also produces less heat than other home concentrators and requires less electricity to operate, reducing your operating costs. There are only 2 filters to replace, so there is minimal maintenance required on this unit.

"Quiet and compact which is exactly what I wanted" Respironics EverFlo Q Home Concentrator

Review by on June 15, 2015

I'm very happy with the Everflo Q! It's my first experience with oxygen therapy because of my COPD and I've been using it for 6 months now. It's quiet and doesn't take up a lot of room, which is what I was dreading.

"Happy with my choice" Respironics EverFlo Q Home Concentrator

Review by on May 26, 2015

I have to use 4 LPM of continuous flow oxygen and this gets the job done nicely. I'm glad I went ahead and got this instead of continuing to use my old tanks. This is much more cost effective for me.

"Really quiet " Respironics EverFlo Q Home Concentrator

Review by on April 20, 2015

My COPD hasn't gotten the best of me because of my EverFlo. I don't mind using this stationary oxygen concentrator because it's not that loud. I use it at night before I go to bed and it helps me fall asleep.

"Super" Respironics EverFlo Q Home Concentrator

Review by on April 6, 2015

This is such a high performance stationary oxygen concentrator. Really impressed with the high oxygen purity and energy efficiency. I use it for a couple hours each day and it didn't increase in my energy bill.

"great" Respironics EverFlo Q Home Concentrator

Review by on December 10, 2014

I have used several concentrators and this is by far the BEST. Mine is around two and a half years old and has never had any trouble.

"Excellent Unit - comfort suggestion " Respironics EverFlo Q Home Concentrator

Review by on January 7, 2014

This unit is reasonably quiet and dependable. Using the water bottle for hydration, maintains comfort from dryness. I do have a suggestion though, the tubing to the sinuses leaves creases in a persons skin when sleeping on the tubing at night. Most people cannot and should not sleep on their back. We have tried cutting the soft sponge wrap from a curler to provide a soft cushion and eliminate the problem. Perhaps Respironics would consider adding a simple sponge/foam soft covering of the tubing on side of face for the home based units- needed only for sleeping. People who are unaware sometimes inquire how and why my wife has the cheek marks or creases. Can be simple to avoid.
