Reconditioned Invacare PerfectO2 Oxygen Concentrator

The Invacare PerfectO2 is a very affordable, whisper quiet and reliable 5 LPM in home - stationary oxygen concentrator unit that is “MADE IN AMERICA “ in either the Ohio or Florida assembly plants.

The PerfectO2 is a sleek and 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. There is a recessed area on the front of the machine to easily place an optional humidifier bottle, which is held in place by a sturdy elastic strap

The Invacare PerfectO2 is designed to reliably deliver 87% to 93% oxygen purity levels while in operation at any setting.

The PerfectO2 is very energy efficient and economical to operate as is uses on average only 280 watts of power at the low flow settings. Coupled with Turn Down technology which slows the operation of the compressor during low flow settings, the compressor will last up to 20% longer than previous versions. During Turn Down operation, the Oxygen Concentrator will consume only 275 watts!

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 PerfectO2 is only 39dbA  and is significantly quieter than earlier models of oxygen concentrators which were louder, heavier and cumbersome.

The maintenance for the Invacare PerfectO2 Oxygen Concentrator is exceptionally minimal and designed to be easy to maintain. At the rear of the Oxygen Concentrator is a foam filter that is placed inside an access door. Simply remove the filter from the access door and clean it in your sink once a week. Let it air dry, and replace it. Annually, you will replace the foam filter as well as the plastic HEPA filter located behind the rear access door. There is also a Bacteria filter inside the machine, located behind the flow meter. While it is a "lifetime filter" designed to be used for 20,000 hours, we do include a new one with our replacement Filter Kits. No tools are needed for the filter changes, unless you decide to change the internal Bacteria filter. Then you will need a #2 size Phillips head screw driver to remove the cover. Total time to change all the filters is about 10 minutes.

The Invacare PerfectO2 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.

Low Purity Sensor

SenseO2 (Low Purity Sensor) is a standard feature for the Invacare PerfectO2 Oxygen Concentrator. The built in sensor ultrasonically measures the purity of output oxygen, to ensure that a safe oxygen level is always maintained while the Oxygen Concentrator is running. If the output of the Oxygen Concentrator drops below 82%, the green "normal" light will switch to a yellow "low o2" light will turn on. The Oxygen Concentrator will provide a visual and audible alarm to indicate that there is an unsafe condition. The user should contact OxygenPlus Customer Service to facilitate repairs or replacement of the machine.

Cleaning  of the Invacare PerfectO2 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 impair 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.

      Happy with the purchase

      The machine is in good condition. When turning it on, the green O2 light comes on quickly, indicating it has reached full saturation on the output. It sounds as expected. However, I was unprepared for the number of hours on the machine. It's above 55,000 hours. I should have asked so my expectations could be properly set. It's used and reconditioned. I am (probably unfairly) comparing it to an identical brand-new unit that I purchased in August 2019 for $650. I only use the unit at night since I live at 7200 ft. above sea level. My newer unit is almost four years old and has just above 15,000 hours on it. I expect this reconditioned unit will last a while since it will be our second unit (used when traveling or deciding to sleep in the TV room).

      Thank you for the review! Despite hours logged from previous use, this machine will run about 12,000 more hours until it needs to be reconditioned again.

      Saved a lot of money

      I was offered a similar, but different brand of machine for lease at $170 per month. That was a no starter for me when I priced new machines and found several available for sale priced at less than $1000. Your website, Oxygen Plus Medical has a hospital approved Invocare Perfecto 2 reconditioned unit for $500, which would pay for itself in saving lease payments. The unit works perfectly and I am very pleased with the purchase.Thank you.

      Noisy concentrator

      It makes too much noise. Every 4 seconds it trumps. They were good on a response and said it was normal. But it's too loud. I can't use it. I really need to send it back.


      OxygenPlus Medical Systems Inc

      All concentrators make that shifting noise. It is part of the normal process of these machines making high purity oxygen. We also have videos of each machine running so our customers can listen to each machine before making their informed decision on which machine to purchase!
