10 Best Radon Monitor 2025 in the United States

The Airthings 2960 View Plus is a versatile indoor air quality monitor that excels in providing real-time data on radon levels, PM2.5, CO2, VOCs, humidity, temperature, and air pressure. One of its significant strengths is the continuous monitoring feature, which allows users to check live data and receive alerts via the Airthings app, making it user-friendly for those who want to keep track of their indoor air quality. The monitor's accuracy, especially for radon detection, is commendable, which is crucial given the health risks associated with radon exposure.

The device is battery-powered, offering a cable-free setup that's convenient for various placements around the home. Plus, it comes with a five-year warranty, providing peace of mind for users concerned about product longevity.

On the downside, the reliance on the Airthings app and internet connectivity might be a drawback for some users who prefer standalone devices. Additionally, while the accuracy is generally high, it requires around seven days for the most reliable radon measurements to be established. Users may also find the initial setup requiring an account a bit cumbersome, though it's a minor inconvenience for the features offered. Another aspect to consider is the product's dependency on an internet connection for some functionalities, which may limit its use in areas with unstable connectivity. Lastly, the ongoing use of batteries (6 AA batteries included) means that users will need to replace them approximately every two years, which could add to the maintenance efforts.

The Airthings Corentium Home Radon Detector is a portable and user-friendly device that excels in providing long-term monitoring of radon levels in your home, a crucial factor for maintaining a safe living environment. Its battery-operated design allows for easy placement anywhere without the need for an outlet, which is a significant advantage for those looking to monitor multiple areas or homes without hassle. The detector offers quick on-screen readings for both short and long-term radon levels, giving users immediate feedback on their home’s air quality. Additionally, it can generate self-inspection reports, making it easier to track changes over time and document radon levels for personal records or professional inspections.

There are a few considerations to keep in mind. While the device provides good accuracy and response time, it may not be as precise as some higher-end models that are permanently installed. The reliance on batteries means that users will need to keep an eye on battery life and replace them periodically, which could be a minor inconvenience. Moreover, while it is lightweight and portable, the compact size might make it easier to misplace.

The Airthings Corentium Home Radon Detector is ideal for homeowners seeking an easy-to-use solution for monitoring radon levels. Its strengths lie in its portability, ease of use, and ability to generate reports, but users should be aware of its battery dependency and potential limitations in accuracy compared to wired alternatives.

The Airthings 325 Corentium Home 2 is a reliable and user-friendly radon monitor designed for continuous home radon detection. It offers proven accuracy with the same trusted technology as its popular predecessor. One of its strengths is the Bluetooth connectivity, which allows you to easily track radon levels through a smartphone app. This app not only shows clear graphs to help you understand how radon levels fluctuate but also provides personalized tips to lower those levels if needed, giving you practical guidance and peace of mind.

In terms of response time, it is built for long-term monitoring, delivering continuous and updated radon readings rather than instant changes. This makes it ideal for homeowners wanting ongoing awareness rather than quick detection in minutes. The device includes temperature and humidity sensors, enhancing the reliability of readings by accounting for environmental factors.

The monitor is portable and battery-powered (using included AA batteries), so it can be placed wherever you need it without worrying about power outlets. Its compact size makes it easy to place discreetly. The visual alarm feature adds an extra layer of alert without relying solely on the app. The smartphone app keeps track of radon trends over time, which helps you see patterns and take action. Calibration and maintenance are minimal since it is factory calibrated and designed to be hassle-free for typical home use. A minor drawback is that it is best suited for long-term monitoring rather than instant radon detection, so it might not meet needs for urgent, short-term testing. Also, the upper temperature limit means it’s best used indoors under normal conditions. This device is an excellent choice for anyone looking to keep a constant eye on their home’s radon levels with easy-to-understand data and helpful advice.
