EverFlo Q Oxygen Concentrator is an ultra-quiet, affordable oxygen concentrator. The Everflo Q is an upgrade to the Everflo Oxygen Concentrator. This medical oxygen equipment combines the small size, light weight and low maintenance of the popular EverFlo Oxygen Concentrator, with the added value of a remarkably quiet sound level. With the Ever Flo Q Home Oxygen Concentrator, you will get the benefits of an ultra-quiet concentrator without the burden of paying an ultra-large price. With a sound level of only 40 decibels, the new EverFlo Q Concentrator operates as quietly as a whisper compared with the 60 decibels of some oxygen machines.

EverFlo Q is lightweight and compact in size, allowing you to easily set it up out of the way of room traffic. The casters on the bottom of this home oxygen equipment make moving the EverFlo Q around a breeze. Because the EverFlo Q Oxygen Concentrator features a dual filtration system, you will spend less time and money on regular maintenance or repair calls. Additionally the new EverFlo Q produces less heat and requires less electricity to operate, reducing owner operating costs.

Oxygen therapy users who wish to live a more active lifestyle favor the portable concentrators over the home oxygen machines particularly if they require only low oxygen doses. When these oxygen users travel, they bring their portable oxygen supply along with them. Some of these portable concentrators weigh less than 10 pounds and are small enough to fit into relatively small spaces.

Failed after 6 months
The unit is lightweight, easy to understand and use and is relatively quiet. Two negatives; 1) Water vapor condenses in the tubes [in 2 units--my Mom's and our own] and 2) ours stopped dead at 6 months. To repair it you have to box it up and ship it to Alabama. AND pay for a loaner. Very disappointing. Am hoping the repaired unit lasts.
extended user
This is a great machine and maintenance is great as long as its under medicare contract. Once the contract time period ends, and the unit is yours, the manufacturer, sellers, dealers and home providers are deaf, dumb and blind to a request for service on a problem machine! Event though an offer of payment is guaranteed..
Where are the filters located at. Quiet machine but I think it has two filters but cannot find one. Please help
Use it and Forget it!
This is how a concentrator should be. turn it on, hook yourself up, get comfortable, and forget its there...

My unit is quiet - which lets me forget about it...
Its small which allows me to hide it out of sight and... forget about it
Its light which means traveling with it is easy!
Now I Travel
I have a Respironcs Q and Evergo Portable: We now can take long overnight car trips because of theses units Size and Weight. I use the Evergo in the car and the "Q" is small t and light enough to pack in trunk and use in Motel.
The Everflo Q is a good quality o2 machine. I recommend it.
Respironics Everflo Q
I chose the Respironics Everflo Q for my mother because it is the lightest of the home oxygen concentrators, so she can move it around if she needs too. Some of the other oxygem machines were 50 lbs.
I was amazed to see how quiet the Everflo was and with only 2 oxygen filters that I don't have to change very often, it helps the pocketbook too.
EverFlo Q Oxygen Concentrator Review
I love this machine. Probably you may be worried about all those complicated and tricky maintenance with this kind of device but it's not the same with it. It has only two filters which means you can save a lot of time. Silence is another attraction. Those who are sensitive with sound like I am will definitely be happy with it.
Oxygen Concentrator Review
My grandfather stays in a home care facility and as a patient with asthma, an oxygen concentrator is a must. One time he had an attack and the facility didn't have a reliable concentrator, so my grandfather waited for about 30 minutes before they were able to make it work. After that, we (me with my parents) decided we should buy him his own so they don't have to ask him to wait. With the Respironics EverFlo oxygen concentrator, we never have to worry about his asthma attacks, the nurses and staff knows how to use it and they commented that it's one of the best and easiest gadget they have used in the facility.
