10 Best Home Radon Detectors 2025 in the United States

The Airthings 2960 View Plus is a comprehensive air quality monitor that excels in detecting radon, a critical concern for non-smokers due to its link to lung cancer. It employs electrochemical sensors to measure radon, PM2.5, CO2, VOCs, humidity, temperature, and air pressure, offering a wide range of data for maintaining a healthy indoor environment. The always-on sensors ensure continuous monitoring, and the data is accessible via the user-friendly Airthings app, which provides real-time updates and historical trends. This makes it easy to stay informed about your home’s air quality and take action when necessary.

Installation is hassle-free, thanks to its battery-powered design, which allows flexible placement without worrying about power outlets. The eInk screen is customizable and provides a clear visual display of essential metrics. On the downside, the device requires an internet connection and an account setup to function fully, which might be a drawback for those looking for a completely offline solution. Additionally, while the provided 6 AA batteries offer a decent lifespan, they will require periodic replacement. The accuracy of radon measurement is reliable after a 7-day period, but initial readings may vary.

The Airthings 2960 View Plus is a robust choice for homeowners concerned about radon and total air quality, offering extensive monitoring capabilities and ease of use, with some reliance on internet connectivity and ongoing battery maintenance.

The Airthings Corentium Home Radon Detector is notable for being the first battery-operated, digital radon detector, making it highly portable and easy to use without needing a nearby outlet. It runs on three AAA batteries, which adds to its convenience. The device is designed for long-term monitoring of radon gas, crucial since radon levels can vary day-to-day. This feature helps homeowners keep track of potentially dangerous radon levels and make informed decisions if action is required.

One of the key advantages is the ability to display both short-term and long-term radon readings on-screen, providing a quick and comprehensive overview of the environment. The capability to generate a radon self-inspection report easily adds to the user control and practical utility of the device. Weighing only 3.52 ounces and with compact dimensions (1"D x 2.7"W x 4.7"H), it is easy to place around the home discreetly.

However, the device lacks advanced connectivity options such as Wi-Fi or Bluetooth, which means users cannot remotely monitor or receive alerts on their smartphones. Also, while it offers decent accuracy for a consumer-grade product, it may not match the precision of professional-grade radon detectors. Calibration and maintenance are simplified due to the nature of its design, but users should still periodically check the device's batteries and functionality. The radon detector is best suited for homeowners looking for a simple, reliable way to monitor radon levels over time without the need for continuous professional intervention.

The Airthings 2930 Wave Plus is a comprehensive air quality monitor designed for home use, offering reliable radon detection along with monitoring for CO2, VOCs, humidity, temperature, and air pressure. This makes it a versatile choice for users looking to have a robust understanding of their indoor environment. Its continuous long-term measuring capability addresses the fluctuating nature of radon levels, which is crucial for accurate detection.

One significant advantage is the ease of use, with a simple wave gesture providing color-coded visual indications of air quality, and Bluetooth connectivity to the Airthings App for more detailed insights. This makes it user-friendly for those who prefer straightforward interaction with their tech devices. However, the product requires regular maintenance, as it is battery-powered, using 2 AA batteries that last around 1.5 years. While this is relatively convenient, it could be a consideration for those who prefer devices with longer battery life or wired options.

The Airthings Wave Plus is also known for its accuracy, with a measurement accuracy of ~10% at 5 pCi/L after 7 days of use. While this is suitable for most users, professional calibration may be needed for those requiring higher precision. Designed in Norway and backed by 15 years of industry experience, the device is trusted worldwide, and comes with a 5-year extended warranty, adding to its reliability and customer assurance. However, the reliance on Bluetooth connectivity might limit real-time data accessibility unless paired with compatible devices like the Airthings Hub or connected through Alexa. For homeowners concerned with a variety of air quality factors beyond just radon, this device offers a comprehensive solution. But for those seeking a dedicated radon detector without additional features, or who need real-time connectivity without auxiliary devices, it might be more than necessary.
