Oxygen Concentrators Buying Guide: Things To Keep In Mind

If you’re looking to purchase oxygen concentrators for a Covid-19 patient, there are a few things to consider before you spend your money.

Oxygen concentrators and cylinders are still in high demand in India as the country fight an increasing number of Covid-19 cases. Although hospitals strive to keep a steady supply, those who are told to recover at home may need concentrated Oxygen to combat the disease. As a result, demand for oxygen concentrators has increased dramatically. The guarantee of an unlimited supply of Oxygen is made by a concentrator. The oxygen concentrator draws air from the surrounding atmosphere, eliminates excess gases, concentrates oxygen, and then blows pure oxygen through a pipe so that patients can breathe normally.

The problem is deciding on the best oxygen concentrator. They come in a wide range of sizes and shapes. It’s difficult to make the best decision when you don’t have enough information. To make it worse, some vendors are attempting to deceive customers by overcharging them for concentrators. So, how do you go about getting a decent one? What are the available choices on the market?

Here, we attempt to resolve this conundrum by providing a comprehensive buyer’s guide to oxygen concentrators, including how they operate, what to consider when running one, and the ones to purchase. Here’s what you should know in case you need one at home.


  • Oxygen concentrators can supply concentrated oxygen on a continuous basis.
  • They come in a wide range of sizes and shapes.
  • Be sure to speak with a doctor about the specific requirements for the patient’s situation.


There are a lot of people selling oxygen concentrators right now. If you can, stay away from them, particularly those who sell them on WhatsApp and social media. Instead, try to purchase an oxygen concentrator from a medical equipment supplier or a Philips approved dealer. This is because these are the only locations where genuine and licenced equipment can be guaranteed.
