Respironics EverFlo is a long-life Stationary Oxygen Concentrator. Designed for individuals looking for something more from their oxygen concentrator, this oxygen machine provides Respiratory Therapy for those who may require 5 liters or less of oxygen flow. Unlike most home oxygen concentrators, the EverFlo is lightweight at only 31 pounds. The EverFlo is quiet, emitting less than 45 dBA. This concentrator features a much more compact, ergonomic design that takes up much less space and produces less heat while using less power, all without the risk of losing performance. The EverFlo Oxygen Machine is available with or without an oxygen purity indicator (OPI).

The user-friendly design of the Respironics EverFlo Concentrator makes life simpler and easier for oxygen users. Respironics' small, quiet design uses less electricity, cutting costs compared with other competitors. The EverFlo features a compact, non-medical design that stylishly fits the user's surroundings. Heavy and bulky oxygen tanks are not necessary so you can avoid coordinating and scheduling oxygen resupply.

Respironics EverFlo is very low maintenance. The internal maintenance-free dual filtration system means that only filter changes are required by homecare providers every two years! The EverFlo features a recessed flow meter and a metal cannula connector to prevent any accidental breakage. The optional Oxygen Percentage Indicator accurately and precisely measures the concentration of oxygen being dispensed. This indicator can be vitally important to strict oxygen therapy dosage requirements. Respironics has also reengineered the humidifier bottle connection, making the EverFlo much simpler to use.

Thank you for your consideration.

In an effort to keep our prices low, we do not bill Medicare or insurance companies. Feel free to contact Medicare for information about reimbursement.
Answer by: Shain Gillet (Admin) on Sep 20, 2017 8:30:00 AM
While using the Humidifier Bottle, understandably it will make the oxygen somewhat more humid to help prevent bleeding, sore, and scabby nasal passages. Is there any possibility of developing pneumonia from humidifying the oxygen?
Than you.

How many hours will these machines last ? mine has 12500 hours and still going. Also, I am confused about changeling a filter-does this machine have a filter ?
Question by: James Terrien on Sep 18, 2016 10:43:43 AM
The concentrator is guaranteed to last three years. The manufacturer does not state how many hours the concentrator will last as part of its guarantee.
Answer by: Shain Gillet (Admin) on Dec 2, 2016 3:29:00 PM
We live at 8300 feet and I noticed the elevation limits on the Invacare Perfecto 2 is 8000' and the Respironics Everflo is 7500 feet. We are looking into buying a unit, but the elevation thing is a concern.
Question by: Robert McDonald on Apr 4, 2017 5:02:00 PM
There are several home and portable oxygen concentrators able to operate at higher altitudes. Many Inogen models, our Visionaire line, the SimplyFlo, EasyFlow5 are just a few examples of what can be used at 10,000 feet. Our customer service agents are available to answer any questions about operation altitude.

How do we connect the oxygen tube to the water bottle on the top of machine?
Question by: pam fenton on Jun 12, 2015 9:25:00 PM
There is one short tube that connects to the top of the water bottle and the O2, then the tube with your cannula or mask on it connects to the water bottle. I just hooked up mine so that's how I know how it's done.
Answer by: Cheri Bickley on Apr 11, 2017 10:25:22 PM
Mine just pushes on. Its a tight fit though.

I hate this machine. It works like a heater that I must keep on. Heats up my home and Jacks up my electric bill!
Nice Machine
I've been renting this same model and it has been costing me a lot, I am so glad to have the very same machine and now it's mine and I'm off the rental merry go round. Thank you
Small footprint, could be quieter but the new Q model improves that. virtually maintenance free. Occasional problem with stopping and beeping with no apparent cause.
Turn on alarm annoying
My husband goes to bed before me and every time I turn on my respirator, the beeeeep is so long and annoying it wakes him up. It is too large for taking on trips and is so noisy I have to put a pillow over it to muffle the sound being careful not to block the intake. I want a quieter, smaller unit without the beeep!
Works Well
The EverFlo works well. No complaints.
Oxygen Concentrator Review
After being asthmatic for 2 years, I decided that I need to really take my therapy seriously. I frequently have to make sure that I lug around an oxygen concentrator when I travel, just for emergency. With this oxygen concentrator that problem was solved. I really love this product!
EverFlo Oxygen Concentrator Review
This unit is very quiet. I run it at night and it does not bother my husband or me at all. It is very easy to use and can easily be moved from one room to another. You can watch Tv and you dont have to hear the oxygen concentrator in the back ground.
