The Best Oxygen Generators for 2021

Everyday life changes when you need extra oxygen on a regular basis. Therefore, portable oxygen concentrators are little, life-changing, and life-saving machines. They afford you the freedom and liberty to do what you want while breathing the oxygen-rich air you need. Read on as we review some of the best oxygen generators for 2021.


1. DEDAKJ DDT-2A Oxygen Generator

With the Dedakj DDT-2A oxygen concentrator, you can conveniently enjoy a healthy life with high-quality oxygen at home. Deda Household Oxygen Generator is the first colored household oxygen generator that breaks the traditional appearance and adopts a modern design style leading the way in household oxygen generator technology.
The Dedakj DDT-2A oxygen generator utilizes an AC230V power supply as an energy source and air as raw material. At normal temperature, it uses a new pressure oscillatory adsorption process (PSA process) for the direct separation of oxygen and nitrogen from the air. Take high purity oxygen. Connect the oxygen generator to a humidified water tank (requires an appropriate amount of purified water to inject) and an oxygen suction tube.


Turn on the power and you can get pure and high purity oxygen for 1-2 minutes. If needed, the Dedakj DDT-2A oxygen generator can continuously deliver high-purity oxygen over a long period of time. Routine maintenance only needs frequent cleaning of the humidified water tank.
The Dedakj DDT-2A household oxygen generator is integrated into the oxygen supply. Oxygen generators overcome the inconvenience of using oxygen bags and oxygen cylinders must first store oxygen and then release oxygen. It also eliminates the need to continuously add oxygen to the chemical oxygen generator. The problem of drugs and the small size of the oxygen generator, which is easy to move, an adequate supply of oxygen can be used where electricity is available.

2. AirSep VisionAire

Airsep VisionAire was launched as one of the best stationary continuous flow oxygen concentrators with some significant improvements in specifications like power consumption, weight, size, and more. The AirSep VisionAire is small and compact compared to many stationary hubs. Its compact size makes it easy to move around the house to store it in the trunk of a travel/interchangeable vehicle.
This machine runs on an alternating current grid and with an energy consumption of 290 W, it is the most energy-efficient oxygen concentrator on the market. It provides continuous flow from 1 LPM to 5 LPM in 0.5 LPM increments. Airsep’s floating ball flow meters are highly reliable and pinpoint the flow rate “provided” by the machine.


The Amber light is on for 5 minutes after the device is turned on until the oxygen purity reaches a certain oxygen saturation level. The device issues an acoustic alarm if the oxygen purity drops below the therapeutic value (85%) for more than 15 minutes. The visual indicator lights up when the oxygen purity drops below the therapeutic level during operation.
The humidifier is located at the back of the machine and has an elastic strap to hold the bottle in place. The VisionAire, unlike its competitors, has no external cabinet/filter, and Airsep claims that the internal filter lasts the entire life of the machine, which makes it maintenance-free.

3. Inogen One G3 System System

Another important Inogen Portable Oxygen Concentrator (POC) system, the G3 system offers a flow of up to 4 pulse settings with attractive features such as a user-switchable screen and alarm text display.

Recognized for its simple-to-use interface, Inogen leaves no stone unturned in establishing it as one of the best POCs on the market today. The Inogen One G3 weighs 4.8 pounds (2.1 kg) with a single 8-cell battery and 5.7 pounds (2.6 kg) with an additional dual 16-cell battery. No other POC on the market is lighter and offers a stream of up to 4 pulse settings.
Inogen has incorporated a user-replaceable small bed function into the G3 system.

Usually, the small bed in every other POC is inside the machine and cannot be replaced by the user. Replacing a small bed is as easy as changing the batteries in the TV remote control. The Inogen G3 is the only pulse-flow POC with an LCD display to display alarms.
Alarms are displayed in the easy-to-understand text along with solutions to the problem.


The most important factor in purchasing a portable oxygen concentrator is oxygen production. To meet your needs, the device must provide you with the appropriate oxygen value. No patient or diagnosis is assimilated, so it is necessary to discuss with your doctor which setting is best for you.
