Oxygen concentrators have been around for a very long time, and as the years went by, companies have developed them to become portable. Thus, the users can enjoy more mobility, and they wouldn’t feel like they are stuck in one place when using these oxygen concentrators. Today, one of the top companies that manufactures these machines is Inogen, which have been providing oxygen therapy services since 2001.
One of the top products that Inogen has sold is their Inogen G3 portable oxygen concentrator, which has sold more than 300,000 units worldwide today. This unit is designed to provide peak comfort and the right amount of oxygen 24/7. This article will provide an in-depth review on the Inogen G3 machine, as told by different users and basing the specifications with other brands and other models.
Size and Weight
The Inogen G3 Portable Oxygen Concentrator has a length of 22.2 cm, a width of 7.6 cm, and a height of 21 cm. This device is small enough for the user to carry like a lunch bag, and the POC set also comes in a carry bag with an adjustable strap to make it more comfortable to wear, no matter your height. Not only that, but the set also has a backpack that you can put the machine in, so that you can go to outdoor activities without the oxygen concentrator being a burden on your shoulder.
Compared to its predecessor, the Inogen G3 model also weighs only 4.8 lbs, or about 2.19 kg, which already includes a single battery. This means that not only is the product small, but it is also lightweight. Even if you carry this around with you all day long, you wouldn’t feel tired or experience aching muscles. Hundreds of customers already say that they don’t feel like carrying a lot when using this product, compared to other larger machines that need to be carried around with a trolley.
This machine provides oxygen in pulse flows, which comes in 5 different settings. The user can easily adjust these different pulses by operating it in the LCD screen. However, unlike other products, the Inogen G3 only provides pulse flow oxygen, and does not have a continuous flow setting.
Pulse flow settings in oxygen concentrators also better reserve oxygen, because not all the oxygen is inhaled in continuous flows. This is also why the Inogen G3 can be small and compact while still providing an adequate amount of oxygen for each pulse. Moreover, this product is highly sensitive, so it can detect whenever you inhale and give you oxygen pulses during that time.
There are two types of batteries available for the Inogen G3 POC: an 8-cell battery and a 16-cell battery, and these batteries are designed to look like a part of the entire machine. The 8-cell battery is the standard battery given in the set, and it can for 4.5 hours continuously at Pulse Setting 3. This battery charges for 2-4 hours, and the actual battery is easy to install and replace.
The 16-cell battery is also optionally available, and this battery will make the entire POC weigh 1.1 lbs. heavier. However, this battery can make your portable oxygen concentrator last for a full 9 hours continuous, which is twice as long as the 8-cell battery. If you’re going for a longer trip where you won’t have a place to recharge or replace your batteries, then you should get this 16-cell optional battery. Plus, this battery will also take longer to charge, taking 4-8 hours.
Just like other commercially available POCs, the Inogen G3 has three different power sources. The first source is the battery, which was previously explained, while the other sources are the DC source in car batteries and the AC sources from electrical outlets at home.
Similar to other Inogen products, the Inogen G3 can function at altitudes of up to 10,000 feet or around 3,048 m. This is also within the usual range of other brands’ maximum altitudes, which is from 8,000 to 10,000 feet. However, the brand with the highest maximum altitude is the Airsep Freestyle, which can reach altitudes of up to 12,000 feet.
If you usually travel on land, then you do not need to worry about these maximum altitudes. Still, you should be mindful about your portable oxygen concentrator when climbing mountains or flying planes, so be sure to inquire about the maximum altitude first.
The buttons and interface of the Inogen G3 concentrator is easy to use, and the LCD screen displays the flow setting, power status, remaining battery life, and the different alarms you set. Compared to other products, customers prefer this kind of interface because the indicators are easier to understand. Even if the POC is operated by someone who does not know how to use it yet, they can still get a grasp of how it works. Different buttons also help you operate between different pulse settings, increase the brightness, and even to turn it off.
The machine also consists of different alarms, depending on the different faults or changes that needs to be done on the machine. Some faults include low battery, low O2 purity, high battery temperature, and others. These easily tell the user what needs to be done, and they can refer to the user manual for further information.
Overall, the Inogen G3 model is one of the bestselling products of Inogen. These Inogen G3 portable oxygen concentrator reviews were compiled from different user reviews, where most have stated that the product is easy to use, lightweight, and effective in terms of delivering oxygen.
It has 5 different pulse settings, and the batteries can last from 4-9 hours between charging times. Lastly, the interface is easy to understand, and the machine will alarm you of the different faults in the machine.
