The Respironics Millennium is a very durable and reliable 5LPM Oxygen Concentrator. Weighing in at only 50 pounds, it is a tall, slender 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.
Operating at 5LPM and 6psi, Millennium is compatible with all of your existing oxygen tubing, and humidifier bottles. Millennium is designed to live up to all of your Oxygen demands.
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 Millennium is designed to reliably deliver 87% to 93% oxygen purity levels while in operation at any setting.
The Millennium is very energy efficient and economical to operate as is uses on average only 360 watts of power. The advanced design of the Thomas compressor allows the Respironics Millennium to run 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 Respironics Millennium is only 48dbA and is significantly quieter than earlier models of oxygen concentrators.
The maintenance for the Respironics Millennium Oxygen Concentrator is exceptionally minimal and designed to be easy to maintain. Once a week you will remove and rinse the foam filter located at the rear of the machine. Let it air dry before reinstalling it. Replace as needed. Annually, you will remove the rear filter door and replace the HEPA filter, as well as the 9 volt battery. Every two years you will need to replace the internal Bacteria filter.
The filter replacement can be done very easily. Unplug the machine. Now you must remove the case of the Concentrator. Two screws in the handle, two screws in the top corners of the front of the concentrator, and two hidden down low. One is under the side cabinet filter. The last screw is in the same spot on the opposite side. Slide the rear cover off and set aside. Slide the front cover off gently. Locate the bacteria filter that is positioned behind the Oxygen Outlet. Remove the filter from the tubing and dispose of it. Install the new filter, reinstall the cabinet pieces, and you are done! The total time for this should take no more than ten minutes. A 2 foot long #2 Phillips screw driver is required to unscrew the case.
The Respironics Millennium 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. The humidifier bottle sits in a recessed area, to minimize the possibility of breakage.
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
OCI (Oxygen Concentration Indicator) is an optional feature available for the Oxygen Concentrator. The built in OCI 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 87%, 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 Respironics Millennium 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.
