Inogen One G5 Portable Oxygen Concentrator - An Expert Review (2023)

Inogen has consistently maintained its position as the leading provider of top-quality portable oxygen concentrators. With its quiet operation, exceptional portability, and ease of use, the Inogen One G5 has quickly become a favourite among those who require supplemental oxygen on-the-go. 

In this article, we'll take an in-depth look at the features and benefits of the Inogen One G5 and provide a comprehensive review of its performance.

Weight

Inogen One G5 portable oxygen concentrator has a lightweight of 2.6 kg including battery, which allows you to carry on with your daily tasks, both indoors and outdoors.

Dimensions and Size

Inogen One G5 is designed with portability in mind. With dimensions of 8.15H x 7.19W x 3.26D inch, the device is very small, easy to carry around on your shoulders.

Control Panel 

Its control panel is super user-friendly. You can easily adjust the pulse flow of the concentrator through the +/- buttons. Everytime you inhale, there is a green light indicator that turns ON on the control panel, which adds to the user-friendliness of the device. 

Silent Operation

With a low noise level of 38dB, it also offers remarkable dampening, so much so that at 1 to 2 pulse settings, you would feel no noise, making it perfectly silent and not disturbing your daily tasks or sleep. 

Flow Output 

Inogen One G5 offers a flow of 6 pulse settings as opposed to 5 pulse settings in most concentrators available on the market. This means that a user will get 1260 ml of flow output at the highest pulse setting of 6 during inhaling, which, when converted to litres per minute, corresponds to 3.8LPM of continuous flow.

User Replaceable Sieve Beds

The best feature of Inogen One G5 is undoubtedly its user-replaceable sieve beds. Sieve beds form the most important component of any concentrator, and they need replacement every 1 to 2 years in portable concentrators. The replaceable sieve beds of One G5 minimise your service centre visits, saving you both time and money.

Battery Backup

For uninterrupted usage, its battery backup is definitely the hero feature. It gives the option of either using a standard 8-cell battery or an extended 16-cell battery. The standard battery gives a backup of 6 hours 35 minutes at the lowest pulse setting of 1. This keeps decreasing as you increase the pulse setting. The extended battery offers 13 hours of backup, which is the highest in the industry, at the pulse setting of 6.

External Charger

It comes with an extended battery that takes about 8 hours to charge. And if you have additional batteries, they can easily be charged from an external charger. This saves you time, and you don’t have to worry about running out of battery even when you are travelling. 

Moreover, you don't even have to insert the battery into the machine for charging, and you can easily check the charging status through the green LED indicator on it.

• 4 LEDs Light: 75% to 100% full
• 3 LEDs Light: 50% to 75% full 
• 2 LEDs Light: 25% to 50% full 
• 1 LED Lights: 10% to 25% full 
• 1 LED Blinks: Battery is less than 10% full and needs to be recharged

Charging Time 

The charging time for a single battery on the Inogen One G5 is up to 4 hours, while the charging time for a double battery is up to 8 hours.

Bluetooth

Inogen One G5 is an innovative device with a Bluetooth feature that helps you monitor its battery life, oxygen purity status, and sieve bed life status.

Operating Altitude

The Inogen One G5 is designed to operate at altitudes ranging from 0 to 10,000 feet, which is equivalent to 0 to 3048 metres.

Flight Use

Its FDA and CE approvals speak highly of its quality. Additionally, its FAA approval ensures you can travel on aeroplanes conveniently. 

Warranty 

Inogen offers a 2 years warranty for the machine, and a 6-month warranty for the sieve beds and battery.

What’s in the box

When you order Inogen One G5, you get one unit of the inogen oe g5 pulse flow oxygen concentrator, a 15 Ampere AC adapter, a car charger for when you are travelling, and a 8/16 cell battery. You also get a sling bag to help you carry the portable unit wherever you go, as well as a salter labs nasal cannula. Additionally, you get a user manual to help you understand how to use the device better by following the instructions.

Cons

While the Inogen One G5 comes with unmatched features, its high cost of Rs. 2.5 lakhs does not make it a budget-friendly portable oxygen concentrator for most Indians. Its high market cost adds to its high maintenance, which further increases its long-term cost.

Final Verdict

When it comes to oxygen therapy in the Indian market, Inogen stands head and shoulders above the competition. In practical terms, though, One G5 is the best oxygen concentrator if you can stretch your budget to Rs. 2 lakh 50 thousand, which may be too much for most people in India.

Furthermore, with expensive machines come expensive accessories, which will increase your costs in the long run. For example, you'll have to budget an extra Rs.75,000 just for the battery. And batteries are one accessory you might need extra of, especially if you travel frequently. 

However, if you are willing to pay that price in exchange for unmatched quality, there is no better pulse flow portable oxygen concentrator on the market than the Inogen One G5.
