What are oxygen concentrators?

How does a home oxygen concentrator work?

An oxygen concentrator takes in normal air consisting of 80% nitrogen and 20% oxygen, takes it through a filtration process powered by a compressor. Once compressed, nitrogen is filtered out through filters in the concentrator and almost pure oxygen is supplied to the user through the cannula depending on the flow rate that the user selects. Usually, the purest form of oxygen is supplied at the lowest flow rate at 1 liter per minute (LPM). A high flow rate delivers less pure oxygen.

Can you buy oxygen for home use?

Yes. However, this should be strictly under prescription. You can have your oxygen supply in liquid or in gas form. Liquid oxygen is easy to store. Gas oxygen, on the other hand, is produced using an oxygen concentrator from the normal air and guarantees you continuous supply.


Buying guide

Planning to buy an oxygen concentrator, here is what you need to consider:

Size & weight

Usually, the heavier units are designed with pushcarts to make them easier to move around with. However, consider your options. If you travel a lot, your selected concentrator should fit in your car trunk, or be convenient to carry in the plane or public means of transport. Again it should be light enough if your needs demand that you move around with it strung to your waist or shoulder.


Oxygen supply options

While some oxygen concentrators supply oxygen in pulse mode, others offer a continuous flow of oxygen. The latter comes as the most suitable option for patients with higher oxygen demand. Still, some have both options. Most portable oxygen concentrators for sale are designed with a flow rate of between 1 and 6 LPM of oxygen with the highest purification level of 90% or more at the lowest flow rate usually 1 LPM. Finally, some come with an auto-adjust feature that increases or decreases oxygen pulse dose depending on the user’s inhale and exhale demands.



The common oxygen concentrator filters eliminate only dirt particles from oxygen. The best models, however, will come with advanced filters that clear bacteria too.



A large enough display that’s colored matters to the elderly as they need easy viewing more than ever. They should also come with large easy-to-press buttons.



When buying an oxygen machine for home use, you need to be very particular about noise levels. Chances are, you’ll be using it at night when sleeping. Concentrators will list their range of noise in decibels (dB) making it easy to select what works for you.



Some intelligence features in a concentrator would include low battery alarm, filter cleaning alarm, malfunction alarm. These useful features make it possible for you to operate your unit properly and cautiously while taking note of faults just in time.



Oxygen concentrators come in a wide range of costs. However, be sure that the advanced, small size portable versions are not exactly cheap. They will cost you anywhere between $ 1400 and $ 3500 or more. It is advisable that you first get a prescription of your oxygen needs from a physician along with a recommendation, then you can begin searching for what is best for your needs and your pockets. You may want to check your insurance options if you have cover.
