All cells in the body require oxygen. If someone’s lungs are unable to get sufficient oxygen on their own for some medical reason, supplemental oxygen is required. This is where an Oxygen Concentrator Works perfectly well by ensuring the constant supply of oxygen enriched air without the need of oxygen cylinders. Oxygen Concentrator is one of the most reliable medical devices for home and hospital use whether for respiratory disease sufferers or after surgeries or even long-term oxygen needs.
You will find out in this guide how an oxygen concentrator functions, what it consists of, the advantages it provides, its applications, and what to consider when purchasing or renting an oxygen concentrator.
What is an Oxygen Concentrator?
An Oxygen Concentrator Machine is a medical device that can remove oxygen from the ambient air, remove nitrogen and provide high-density oxygen to the recipient. Concentrators continuously generate oxygen as long as there is power, instead of a limited supply like oxygen cylinders.
The ambient air has a concentration of about:
- 78% Nitrogen
- 21% Oxygen
- 1% Other gases
An oxygen concentrator is a medical device that uses advanced filtration technology to extract oxygen from nitrogen, and provides oxygen in about 90%-96% pure.
How an Oxygen Concentrator Works
Knowing how an Oxygen Concentrator Works can be made much easier to understand by breaking it down into steps.
Step 1: Air Intake
First, the machine draws the normal room air through the external air filter. The filter traps the dust, dirt, pollen and airborne particles prior to their entry to the inside system.
Clean air guarantees improved oxygen purity and guards the inside components from harm.
Step 2: Air Compression
The filtered air is fed into a compressor.
Compressor boosts air pressure prior to feeding it to the molecular sieve beds. The efficiency of the oxygen separation is enhanced by pressurized air.
Step 3: Nitrogen Separation
This is the most important process within an Oxygen Concentrator Machine.
Two cylinders, each containing Zeolite molecular sieves, are used to compress the air.
These sieves are made with very small holes that only N2 molecules can fit into and oxygen molecules can fit out.
This gives a very high concentration of oxygen.
Step 4: Oxygen Collection
When the N2 is removed, O2 builds up in a storage tank.
The level of purity of most modern oxygen concentrators is around 90%-96%, based on the flow rate.
Step 5: Oxygen Delivery
The purified oxygen is then provided to the patient via:
- Nasal Cannula
- Oxygen Mask
Flow rates are modified to fit doctor’s prescription.
Common flow rates are:
- 1 LPM
- 2 LPM
- 3 LPM
- 5 LPM
- 10 LPM
Step 6: Nitrogen Release
The nitrogen gas is released into the atmosphere in a safe manner.
The machine alternates between two sieve beds continuously, ensuring an uninterrupted oxygen supply.
This is a process that continues on and on, every few seconds.

Pressure Swing Adsorption (PSA) Technology
Pressure Swing Adsorption (PSA) technology is the type of technology used by most modern oxygen concentrators.
The process includes:
- Compressing room air
- Passing it through Zeolite sieve beds
- Capturing nitrogen
- Collecting oxygen
- Releasing nitrogen
- This appears to be a continuous process
PSA is a technology that enables continuous oxygen production without the need for tank replenishment.
Oxygen Purity
The majority of high-quality oxygen concentrators deliver the following:
| Flow Rate | Oxygen Purity |
| 1 LPM | 95–96% |
| 2 LPM | 94–95% |
| 3 LPM | 93–95% |
| 5 LPM | 90–93% |
Depending on the brand and the capacity of the machine, there may be variations in purity.

Who Needs Oxygen Therapy?
All those that have low levels of oxygen in their blood consistently are recommended oxygen therapy.
Common diseases are:
- COPD
- Chronic Bronchitis
- Pulmonary Fibrosis
- Pneumonia
- Asthma (severe cases)
- Check-ups for COVID-19 recovery (under medical supervision)
- Sleep Apnea with low oxygen levels
