What is the difference between an oxygen concentrator and an oxygen generator?

An oxygen concentrator is a machine that takes in air from the room and delivers oxygen-enriched air to the patient through a nasal cannula. An oxygen generator, on the other hand, produces oxygen from scratch using chemical reactions.

What is an oxygen concentrator?

An oxygen concentrator is a medical device that delivers oxygen to the body. It is used to treat patients who have difficulty breathing. The device contains a tank of compressed air and an oxygen generator. The oxygen generator creates oxygen by breaking down the air into its component parts. The oxygen is then delivered to the patient through a mask or nasal cannula.

What is an oxygen generator?

An oxygen generator is a device that produces oxygen from a chemical reaction. The most common type of oxygen plant generator uses a process called electrolysis to split water molecules into hydrogen and oxygen.

The pros and cons of each

If you're considering whether an oxygen concentrator or generator is right for you, it's important to understand the pros and cons of each.

Oxygen concentrators are typically smaller and more portable than generators, making them a good choice for people who are active and need to take their medical psa oxygen plant with them. They're also quieter and have a lower risk of fire. However, they're more expensive to operate, and the oxygen they produce isn't as pure as what you'll get from a generator.

Generators, on the other hand, are less expensive to operate, and they produce purer oxygen. But they're bigger and heavier, so they're not as portable. They also produce a lot of noise, and there's a greater risk of fire.

How to choose the right one for you

There are a few things to consider when choosing between an oxygen concentrator and an oxygen generator. First, think about how often you need to use oxygen. If you only need it occasionally, an oxygen concentrator might be the best option since it is smaller and more portable. However, if you need oxygen on a daily basis, an oxygen generator might be a better choice since it can provide a continuous supply of oxygen.

Another thing to consider is the cost of each option. Modular Oxygen Plant concentrators typically cost more than oxygen generators. However, they may be covered by insurance if you have a medical condition that requires you to use oxygen therapy.

Finally, think about the size and weight of each option. Oxygen concentrators are usually smaller and lighter than oxygen generators. This can be important if you need to take your oxygen therapy with you when you travel.

If you're not sure which option is right for you, talk to your doctor or respiratory therapist. They can help you make the best decision for your needs.


There are a few key differences between oxygen concentrators and oxygen generators. Oxygen concentrators use a sieve-like device to remove nitrogen from the air, leaving behind concentrated oxygen. On the other hand, oxygen generators create oxygen by using a chemical process. Oxygen generators are usually larger and heavier than oxygen concentrators, making them less portable. However, they may be a better option for people who need a higher flow of oxygen.
