An oxygen concentrator is used for oxygen therapy for chronic patients who need more than what is available in ambient air. It shouldn’t be too hard to buy a unit for your own, but having to buy something portable is something else. We’re here to show you how to choose a unit that doesn’t fall too short of the standard oxygen concentrator for home use and show you the best portable oxygen concentrators for sale.

Before we get started, let’s go ahead and take a look at your doctor’s prescription to see what features you would need for that unit you’re planning to buy. Purchasing a unit haphazardly can cause more harm than good, especially if you don’t understand what you’re looking for. So let’s get started with our guide.

Reading and understanding your doctor’s prescription


We all know how daunting it is to read a doctor’s handwriting, but that’s not what we mean by understanding the prescription. You might see something like LPM which means Liters Per Minute and it’ll go something like “2 LPM Pulse/Conserving” or something like “3 LPM Continuous Flow” which probably sounds like alien language to you right now.

First, let’s try to get the idea on what those terms mean, since they always say that “learning is half the battle”. You should know that there are 2 types of Oxygen Concentrators, one with Pulse Dose and the other with Continuous Flow. These are also not interchangeable; if your prescription demands a Pulse dose machine, you can’t get a continuous flow with it and vice versa.

What else?

Now that we know the different types of oxygen concentrators out there, here are some other criteria that you may want to keep in mind when you before you go ahead and make a decision to buy a unit.

  • Battery
    • You may want to look at a unit with a long and extensive battery life since you wouldn’t want it to just drop dead during a session. Aside from that, nothing else power related should be an issue since all oxygen concentrators, even the portable ones, can be AC or DC powered.
  • Size
    • You’re not going to want to haul a huge piece of equipment everywhere you go right? You’ll want to get the smallest unit with all the features you need.
    • That goes into consideration that it should also be light and easy to carry, a small but heavy machine cannot be considered portable.

These are all the things you would need to know in order to purchase a good system. Armed with this information, it should be easier for you to find a machine that would suit your needs. Just always remember that there are two types of oxygen concentrators and it’s highly advised that you don’t mix them up. That aside, we’ve put up some of our recommendations to help you out in getting the machine you need.
