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.
