For years, oxygen concentrators were used to provide oxygen therapy for people with breathing problems, but these machines are usually installed in one place, so the user doesn’t get to do much all day. This is why portable oxygen concentrators were developed by the turn of the 21st century, and these machines provided more mobility and better concentrations of oxygen.
One of the popular brands that provide high-quality portable oxygen concentrators is RedMed, and their most popular unit is the RedMed Activox 4L, a small and lightweight POC that can provide large amounts of oxygen per minute. Several Activox portable oxygen concentrator reviews have already said that this machine is their favorite, and in this article, we will list down all the reasons why you should buy this product.
Size and Weight
Portable oxygen concentrators are designed to be smaller and more mobile than the ones found in hospitals, and Activox is no exception. Its dimensions are only 9.05” W x 7.875” H x 4.38” D, and weighs only 4.8 pounds. In comparison, the smallest POC in the market is the AirSep Focus, with dimensions of 4.8” W x 6.4” H x 2.5” D and weighs 1.75 pounds. This means that Activox 4L is already pretty small, unlike the other larger POCs that need to be carried in a cart.
Carrying the Activox portable oxygen concentrator is also easy. In fact, when you buy this product, you will also get a carry case with four different carrying styles: waist, backpack, briefcase, and shoulder carry. Therefore, you can do a lot of different activities without the machine being a hassle. Plus, this carry bag also has adjustable straps, so you can adjust it to your comfort.
The Activox 4L provides oxygen in pulse flow doses, and this unit comes with four different pulse settings. At setting 4, this machine can deliver up to 480 mL/min at setting 4, and it is already considered to be pretty high for its type. The portable oxygen concentrator with the highest pulse oxygen dosage is Inogen One G5, which can provide oxygen at 1260 mL/min at its maximum setting. Moreover, this device also has a sensor that can detect when you inhale, so it will deliver pulses of oxygen during that time. The oxygen concentration is also higher than the usual POCs available, which is 90-95%.
Activox 4L does not have a continuous flow setting unlike other brands, but this is also helpful for saving battery and reducing wasted oxygen that wasn’t used. Moreover, the motor of a portable oxygen concentrator without a continuous flow setting is also smaller, which is why the Activox 4L is small and lightweight, perfect for traveling.
Like most portable oxygen concentrators, the Activox 4L is equipped with a battery that can be used for traveling and doing outdoor activities. This unit has two types of batteries: an internal battery and an external battery. The internal battery can last more than 8 hours when used at setting 2, which is already above the average battery life of other POCs. Meanwhile, an external battery can also be attached to this device, which can add at additional 4 hours to the machine at setting 2.
Other than the battery, there are also two other ways for you to charge this device. One option is through an AC source, just like the wall sockets in your home. The other option is a DC source, which is through the socket in your car. Either way, your POC would take up to 4 hours to charge, especially if it were fully drained.
If you are a person that likes to climb mountains or travel via planes, then you might also want to consider the maximum operational altitude of your portable oxygen concentrator. Normally, most POCs have maximum altitudes that range from 8,000 to 12,000 feet, and Activox 4L is well within that range at 10,000 feet. Moreover, this unit is also FAA approved for airlines, so you don’t have to worry about it being damaged when you ride planes.
Just like the newer models of portable oxygen concentrators that we have today, the Activox 4L is equipped with an LCD display that is easy to use and simple to operate. This digital display can indicate the remaining battery life, external battery connection, pulse setting, and different messages and warnings. Plus, there are also buttons near the display that you can use to operate between pulse settings, or even to turn the machine on or off.
The Activox 4L also has different alarms that will tell you if there is something wrong with the machine. You can choose to mute the machine if you are somewhere important, but don’t forget to unmute this in order to avoid emergencies!
