If you have been searching for an oxygen generator for home use in South Africa, here is the good news: for medical purposes, an oxygen generator and an oxygen concentrator are essentially the same machine. “Oxygen generator” is simply the everyday name many people use – the medical device that generates concentrated oxygen from room air is called an oxygen concentrator.
How Does a Home Oxygen Generator Work?
An oxygen concentrator draws in normal room air, which is roughly 21% oxygen, and passes it through sieve filters that remove most of the nitrogen. What comes out is concentrated oxygen – typically 90-95% – delivered through a nasal cannula or mask at the flow rate your doctor prescribes. Because the machine makes oxygen continuously from the air around it, it never needs refilling the way an oxygen cylinder does.
Medical vs Industrial Oxygen Generators – An Important Difference
Not every machine sold as an “oxygen generator” is intended for people. Industrial oxygen generators are built for welding, fish farming and manufacturing, and are not safe for medical use – they are not designed to deliver breathing-grade oxygen at a controlled, prescribed flow. If the oxygen is for a person, always choose a medical-grade oxygen concentrator and follow the flow settings prescribed by your doctor.
Home and Portable Options in South Africa
Medical oxygen concentrators come in two main forms. Home oxygen concentrators (5L and 10L) plug into a wall socket and are made for continuous use at home. Portable oxygen concentrators run on rechargeable batteries so you can leave the house, travel and stay active.

Should You Rent or Buy?
If you need oxygen for a limited period – for example after a hospital stay – an oxygen concentrator rental is often the practical choice. For long-term oxygen therapy, buying usually works out more economical. Our team can help you weigh it up for your situation.
