With the Airthings Corentium Home 223 Radon Gas Detector, it’s now possible to get an idea of the real-time radon levels in your home.

Airthings Corentium Home 223 Radon Gas Monitor

Radon gas is a silent and invisible health risk that lurks right under your nose, without you being aware of it. Exposure to this gas is one of the possible causes of lung cancer.

In fact, approximately 21,000 lung cancer-associated deaths every year are attributed to radon exposure (Ref: US Environmental Protection Agency), making it potentially one of the leading causes of lung cancer in non-smoking individuals.

To make sure that you and your family are safe and healthy, it’s important to monitor the levels of radon gas in the air in your home. One of the most commonly used methods of monitoring indoor radon levels is through the use of single-use charcoal kits.

However, these kits can be used only once and have to be sent to a lab for results.  As a result, people are on a lookout for options that are more convenient and offer quick and accurate results.

Airthings Corentium Home 223– An In-Depth Review

The Corentium Home 223 is a simple digital instrument that measures the radon gas levels in your home. It’s a battery-powered device that runs on 3 AAA batteries. It enables you to monitor the levels of radon in your home in real-time. It tells you how much radon is present in the air inside your home, without you having to send any samples to the laboratory. It’s a quick and highly efficient way of keeping the levels of this deadly gas in your home well in check. 

How Does It Work?

The Airthings Corentium Home 223 is a powerful instrument that provides highly accurate results. When you first turn the instrument on, it takes about a minute for it to self-calibrate.

Once the calibration is complete, you should keep it anywhere in your home, at a spot that is ideally the center of the room. It takes the Airthings Corentium Home approximately 6 to 12 hours to provide the first readings. 

You’ll see two separate readings on the large LCD display; a short-term average and a long-term average. These readings are displayed in pCi/L in the US model and Bq/m3 in models used elsewhere in the world.

It provides accurate readings faster than any other radon gas monitor available in the market today. On the 7th day, the Corentium Home 223 will display a short-term average reading between two readings – one-day reading and 7-day reading. Don’t worry if these two values are contrastingly different. What makes the Corentium Home 223 such a trusted and reliable product is its short-term average reading. 

What Sets the Airthings Corentium Home 223 Apart?

The Airthings Corentium Home 223 is getting popular for all the right reasons. It’s equipped with various features that set it apart from the traditional charcoal kits for detecting radon in air. Let’s have a look at the most noticeable features that account for its popularity.

Simplistic Design

Airthings has kept the design of the Corentium Home 223 extremely simple and straightforward. The product is solely targeted to do what it needs to do – provide accurate readings in a short time and that it does excellently.

The Corentium Home 223 features a large LCD display, with no buttons or controls on the front side. It has 2 small buttons on the backside. These buttons are only meant for occasions when you wish to reset the instrument to see how long it has been in use.

Other than this, it’s also equipped with a micro-USB port that isn’t meant to be used by the users but only by service technicians for the purpose of unit service. In a nutshell, the Airthings Corentium Home 223 features a no-nonsense design that is a highly accurate scientific equipment to its core. 


Detecting and monitoring the radon levels in your home becomes extremely convenient with the Airthings Corentium Home 223. All you’ve to do is place the instrument anywhere in your home, and let it sit for 6 to 12 hours.

The results will be displayed on the LCD screens. You don’t have to worry about leaving the instrument for several days and then arrange for it to be sent to the testing lab, where the results can be compiled.

Another feature that makes this instrument one of the most convenient radon detectors is that it’s battery-powered. You don’t have to struggle with finding a suitable spot to place it that has an electrical point.


What makes the Airthings Corentium Home 223 one of the best options is its accuracy. It provides highly accurate readings in a much shorter duration. You can completely rely on what this radon detector tells you. It features advanced technology that is more than often reserved for commercial-level radon detectors.

One Instrument for the Whole House

Another reason why the Airthings Corentium Home 223 stands out among other radon detecting options, primarily the charcoal kits, is the fact that it’s not a single-use instrument.

Unlike a charcoal kit, you can place the same instrument anywhere in your home where you wish to check the levels of radon in air. Once you get the readings for one portion of your home, you can move the device to the next room.

Although it costs much more than the traditional charcoal kits, it’s definitely worth the cost.

Continuous, Long-Term Monitoring

Once you switch the Corentium Home 223 on, you can let it be. It’ll monitor the radon levels in the air continuously over a long period – for as long as you want. Since the level of radon in the air keeps fluctuating drastically, a long-term data collection will help you keep track of how frequently and by how much margin the radon levels are changing.

Radon Level Report

It seems like the Airthings Corentium Home 223 is the ultimate radon detector, one that literally fulfills all the needs when it comes to monitoring radon levels in the air. It enables you to generate a quick report any time you want so that you can review the radon levels over a specific period of time, and take actions accordingly if need be. 

Limitations of the Airthings Corentium Home 223

As much as the Corentium Home 223 by Airthings is a commendable radon detector, it does come with some limitations.

No Alerts

One major drawback of the Airthings Corentium Home 223 is that it doesn’t come with an alert feature. It means that if the levels of radon in the air exceed the safe limit, it won’t ring to raise an alarm.

If you don’t go to see the display, you won’t even know when the radon levels get dangerously high. It’s something that should’ve been a part of the instrument.

It would’ve made monitoring the radon levels and ensuring they don’t exceed the value that’s considered safe easier. 

No Extra Storage Memory

Another limitation of the Corentium Home 223 is that it doesn’t have any additional storage memory. It stores the data for up to a certain period. However, if you want to retrieve older data, it won’t have that data stored.

A Simple Radon Detector

The Corentium Home 223 is a simple radon detector, and that’s it. Other models have additional features, like the ability to monitor temperature, pressure, humidity, etc. If you want to monitor these factors, you’ll need a separate device for it.

How Does It Compare to Other Airthings Radon Detectors?

You may want to be sure before you can invest in the Corentium Home 233. Below is a comparison of the Home Corentium 233 with other Airthings products, to help you decide if it’s the right product for you.

Corentium Home vs. Wave

The Corentium Home, which we’ve discussed in detail above, is a simple and user-friendly radon detector, but that’s all it is. In comparison, the Airthings Wave is a smart detector that provides you with accurate, real-time results on your smartphone.

What’s more, is that you can get a visual identification of the current radon levels by simply waving in front of the device. The Corentium Home only provides radon level readings, but the Wave also provides temperature and humidity data. 

Another difference between the two models is that the Corentium Home features a display screen whereas, there’s no display screen in the Wave. Wave is not battery-operated like the Corentium Home either. Since Wave is a smart device, it’s equipped with Bluetooth and Smartlink. Unlike the Home Corentium, it also provides an hourly readout.

Corentium Home vs. Wave Plus

The Airthings Wave Plus is the first battery-powered smart radon detector. Other than radon detection, it’s also capable of monitoring the temperature, humidity, air pressure, carbon dioxide, and VOCs.

Unlike Corentium Home, the Wave Plus doesn’t have a display screen. Moreover, it’s equipped with everything that Airthings Wave has, including Bluetooth, Smartlink, and hourly readout – all the Corentium Home doesn’t have.

Corentium Home vs. Corentium Pro

Corentium Pro is an advanced version of the Corentium Home, so you can expect it to have some advanced features. It’s certified by the AARST-NRPP and is capable of monitoring radon levels along with the temperature, humidity, pressure, and tilt.

Although it lacks a display screen, it does have a readout software. It also has extra memory for storing data over a long time. Additional features include a tripod
