Reconditioned Respironics EverFlo Oxygen Concentrator

The Philips Respironics Everflo is a very affordable, whisper quiet and reliable 5 LPM in home - stationary oxygen concentrator unit that is “MADE IN AMERICA “

The Everflo’s footprint is a small, slim, sleek, attractive, lightweight design. Weighing in at only 31 pounds, it is a compact unit that fits into most any space. It has a built in rugged handle on the top of the machine, and features four large caster wheels which allows for ease of movement and mobility.

This Oxygen Concentrator has an adjustable flow meter which ranges from .5 LPM to 5 LPM that is adjustable in ½ LPM increments which can accommodate the various needs of most oxygen end users. The adjustable flow meter is also recessed into the body of the concentrator so as to minimize the potential for damage to the flow meter.

The Respironics Everflo is designed to reliably deliver 87% to 93% oxygen purity levels while in operation at any setting.

The Everflo is very energy efficient and economical to operate as is uses on average only 350 watts of power. The advanced design of the Thomas compressor allows the Everflo to run ultra quiet, cooler and uses less electricity therefore saving the user from incurring higher energy bills.

This Oxygen Concentrator will provide you with several years of safe, reliable and trouble free service and is designed to operate effortlessly and efficiently on a 24/7 basis.

The sound level of the Everflo is only 45 db and is significantly quieter than earlier models of oxygen concentrators which were louder, heavier and cumbersome.

The maintenance for the Respironics Everflo Oxygen Concentrator is exceptionally minimal and designed to be easy to maintain. It only require a filter cartridge replacement only once every year. There are no filters to clean weekly, as there are with all other models of oxygen concentrators out on the market today.

The filter replacement can be done very easily by removing the filter door on the top right rear of the unit, gently removing the existing filter by pulling on it and firmly pressing the replacement filter cartridge back into place and replacing the filter door cover. The total time for this should take no more than one minute.No tools required.

The Respironics Everflo is available with a humidifier bottle option, that is used with distilled water only. This humidification moistens the high purity oxygenated air so that it minimizes the discomfort to the patients nose and throat from the air being to dry.

This oxygen concentrator is designed for home settings or at any location where a long life stationary unit can be used which operates on 120 VAC and 60 HZ.

The concentrator should never be used in conjunction with extension cords, power strips or surge protectors as it will interfere with the proper operation and potentially cause the concentrator to overheat or have other operational issues.

Cleaning of the Respironics EverFlo Oxygen Concentrator

Periodically, you will want to clean the exterior of your Oxygen Concentrator to keep it looking as well as it runs. It is important that you unplug the machine while cleaning it. Using a damp cloth, gently wipe the exterior of the machine. Using cleaning tools such as cotton swabs is perfectly okay, to clean the hard to reach areas. If using a medical disinfectant, make sure to follow all manufacturers instructions. Let the machine air dry before operation, as excess moisture may impare the proper operation of the device.


How does an oxygen concentrator work?
An Oxygen Concentrator is an electrical piece of equipment. You plug it in to the wall outlet of your home. Make sure it has at least 6 inches of room all around it to allow ample air flow. When you turn the machine on, it will bring in air from the room around it. First, the air passes through a couple of filters to clean the air before it enters the compressor. Once inside, the compressor will pump the air into a pair of Sieve Beds. Once the Sieve Beds are pressurized, the material inside called Zeolite will cling on to the Nitrogen, and pass on the Oxygen and other trace gasses to the patient. Every ten to twelve seconds, the internal Valves will switch the air from one Sieve Bed to the other. This produces a rhythmic "breathing" sound from your Oxygen Concentrator, and is normal. During the breathing of your Oxygen Concentrator, the Nitrogen that was in the Sieve Bed is released back in to the rooms atmosphere. Oxygen Concentrators are designed to run 24 hours a day, seven days a week if needed.

What percentage of oxygen does an Oxygen Concentrator deliver?
Oxygen Concentrators are designed to reliably deliver 90% oxygen +/- 3% at any flow rate. This purity has been tested to be clinically acceptable for long-term oxygen therapy.

How often should I clean filters and other accessories?
If equipped, the foam Cabinet Filter on your Oxygen Concentrator should be rinsed in your sink every week. Let it air dry before placing back in the Oxygen Concentrator. The bubble humidifier should be washed daily using a mild detergent and hot water. Tubing, Cannulas, etc are not to be cleaned. Simply dispose of and replace as needed.

Can I purchase a Low Flow (Pediatric) meter for my Oxygen Concentrator?
Most Oxygen Concentrators can be ordered with, or retrofit with a Pediatric Flor Meter. Please call for availability.

What length of Oxygen Tubing can I use with my Oxygen Concentrator?
The maximum recommendation is not to exceed a Bubble Humidifier, a 50 foot long extension hose, and a 7 foot long Nasal Cannula

How can I transport an Oxygen Concentrator in the car?
The optimum way to transport an Oxygen Concentrator is to buckle it in to the back seat, or place it on the rear floor of your vehicle. If necessary, you can safely lay it on it's back in the trunk if it is securely held in place.

Can I use my Oxygen Concentrator overseas?
The Oxygen Concentrators listed on this site are made specifically for US Voltage requirements, which is 110 Volts and 60Hz

What is Turn Down technology?
This Oxygen Concentrator incorporates Turn Down technology. The internal Circuit Board constantly monitors the flow rate and will slow down the compressor at lower Flow Rates. As a result the unit runs cooler and less power is consumed. In turn, you will have a lower power bill, and the Oxygen Concentrator should run longer.

How can I tell if the oxygen purity is good?
If equipped with a Low Purity Sensor, as long as the Green LED light is illuminated, you know that the Oxygen Concentrator is making at least 85% purity Oxygen. If for any reason the Purity falls below therapeutic levels, the Yellow LED light will illuminate. Contact your provider if you notice this.

      Everything about this purchase was exceptional

      I was previously receiving service from a local company that was being paid for by Medicare. They made a two month mistake in failing to contact my doctor to renew my prescription and refused to make it right, even though it was their error. I decided to buy my own machine and found the refurbished machine here. The price was very reasonable and I ordered. It was delivered four days later, which was yesterday. After unboxing the unit and plugging it in, it started working immediately and kept my oxygen levels right where they should be. It is a lot quieter than the old one and I am completely happy with the purchase. The fact that they shipped it immediately and it was delivered in four days is impressive. The machine works flawlessly and was reasonably priced. I don’t have to worry about dealing with the company that has such bad customer service. I highly recommend Oxygen Plus Concentrators.

      Best customer service ever!

      I called this company to discuss needs for my mom about a refurbished concentrator and the nicest, most genuinely helpful man, Larry answered the phone. What a breath of fresh air!!! He was so kind and patient with my questions and needs. Explained everything to me and proceeded to take my order over the phone. He promised it would go out that week and it did! I live in Nevada and I had it in six days! He added an extra filter and an adapter I needed at no cost which was so appreciated. I recommend this company so highly that I will not do business anywhere else. Professional, efficient, knowledgeable, patient, kind, affordable and speedy delivery. The concentrator works great! Many businesses could learn from them.
