Corentium Home Radon Detector Review

Radon is a radioactive gas that forms from the natural decaying of radioactive elements. It’s mostly formed in the soil and in rocks but when it goes airborne, and into the water, that’s when it becomes a real health hazard. For anybody looking to provide a safe environment at home or at the workplace, a radon detector is a tool that you’ll definitely want to consider purchasing.

Easy Installation

The Corentium Home Radon Detector isn’t too different from a thermostat in both appearance and installation. After popping the unit out of its packaging, all you need to do is put three AAA batteries into the compartment and wait a few minutes for the tool to calibrate. After that, it takes between 6 and 12 hours for the radon detector to give you an initial reading. Every subsequent reading will is lightning fast.

There’s really no way to define how accurate this tool is without the help of a lab. After employing the assistance of a lab, we found a 20% variance between the radon detector’s readings and the lab’s. This is quite far from the 5% variance promised by the manufacturer.

However, as the lab experts put it, this may not be a direct indication of accuracy or lack thereof since a number of different variables come into play; the most important of which is that the Airthings radon detector can identify the presence of radon gas in multiple rooms whereas their readings were limited to a single room in our test environment.

Real-Time Readings

The read benefit that you get from this Airthings radon detector is real-time, easy-to-read readings. Unlike charcoal kits which require the help of labs, after the initial 6 to 12 hours of waiting, this detector will give you clear and concise readings of how contaminated the air is in your home (readings are in Picocurie per liter of air or pCi/L). Seven days after installation, the unit will also show an estimate for how contaminated the air will be one week into the future.

No Memory for Storing Readings

This unit does not have any built-in memory or slots for external memory to store past readings. What you see on the LCD display is what you get, and there’s no way to compare past the current readings of radon gas. The only thing you can do is manually record the presence of radon gas and compare it to future readings.

Lack of Alerts

If there’s a poisonous gas in high amounts in the confines of your home, wouldn’t you want to be alerted of its presenceAfter all, smoke detectors scream in our ears during the night when cooking up a midnight snack, so it only makes sense that a radon detectors wakes up the entire neighborhood if we’re possibly breathing in toxic fumes.

Unfortunately, there are no such alerts in this radon detector. Your responsibility to manually check the unit to see how tolerable the radon gas quantity in your home is. As a reference, the US’ Environmental Protection Agency has defined “safe” levels to lower than four pCi/L.

Mobile App

You can get instant readings on your phone by installing the free-to-download app. It displays everything that you’d normally see on the unit’s LCD display panel but in the convenience of your pocket device. Furthermore, you can save the recordings onto a PDF file. There are no alerts, but at least this somewhat relieve the problem of a lack of storage space in the tool.

Battery Lifespan

The Airthings Home Radon Detector runs on three AAA batteries. The hardly uses any power, and each three-pack provides you with around two years of radon gas detection. Having to change batteries in detectors frequently can be a hassle, so we’re glad that this tool gives us a 2-year window to delay purchasing fresh batteries.


So, after all, we’ve learned about the Corentium Home Radon Detector from Airthings, we can safely conclude that it’s a pretty neat tool to have to ensure the safety of your home or workplace’s air quality. The lack of alerts is something that’s a huge turn-off for us.

You’ll either need to constantly monitor the built-in display or the Airthings app on your mobile device to ensure that the air quality in your home is constantly below the four pCi/L threshold set by the EPA. Other than this major flaw, this is definitely a tool that could benefit your home.
