Choose the Wave Radon for app-based trend checks, or the original Corentium Home for simple readings on its screen. Corentium Home 2 adds Bluetooth, humidity and temperature readings, making it the most feature-rich choice of these 3.

All 3 are battery powered radon detectors from Airthings. The main differences are how you view the readings and whether you want humidity and temperature data as well.

The Wave Radon and Corentium Home 2 both connect to the Airthings app over Bluetooth. The original Corentium Home 223 keeps its readings on an LCD screen.

Airthings Wave Radon vs Corentium: what is the main difference?

The Wave Radon is built around app access, while the original Corentium Home puts average radon readings on its LCD screen. Both are portable, battery-powered detectors for ongoing radon monitoring.

Wave Radon measures radon, humidity and temperature. You can get short- and long-term radon results through the app when your phone is within Bluetooth range, and check trends over time.

The original Corentium Home displays daily, weekly and long-term radon averages on the device. Its 3 AAA batteries make it easy to move between rooms, and you can generate a radon self-inspection report.

The newer Corentium Home 2 combines an on-device display with Bluetooth app access. It also adds humidity and temperature sensors, plus GOOD, FAIR or POOR indicators on its redesigned display.

If you're still deciding what readings matter to you, start with our guide to how to choose a home radon monitor. It explains why monitoring over time matters and what to consider when picking a device.

Which model gives you the clearest view of readings?

Choose Corentium Home 2 for both screen and app views; pick the original Corentium Home if a screen is enough. Wave Radon is a fit if you prefer checking detailed results and trends through the app.

Wave Radon gives a color-coded visual indication when you wave in front of it. For detailed results, connect it to the Airthings app to check current short- and long-term averages and review trends.

Corentium Home 223 keeps the basic view close at hand. Its LCD screen shows daily, weekly and long-term averages, so you don't need Bluetooth to get a reading.

Corentium Home 2 offers both routes. Its display shows short- and long-term averages, environmental readings and simple GOOD, FAIR or POOR indicators, while the Airthings app provides graphs.

A simple indicator can help you scan a result quickly, but don't treat it as a substitute for understanding the actual readings. Our guide to how to read air quality monitor numbers explains why time period and context matter.

What does Corentium Home 2 add over the other two?

Corentium Home 2 adds Bluetooth, app graphs, humidity and temperature sensors to an on-device radon display. Pick it if you want those extra readings in one portable detector.

Wave Radon also measures humidity and temperature and connects to the Airthings app by Bluetooth. Corentium Home 2's distinction is that it pairs those sensors and app graphs with its own display of averages and indicators.

The original Corentium Home is the simpler option in this group. It shows radon averages on the LCD screen, without Bluetooth connectivity or the additional humidity and temperature sensors described for the other 2.

For a closer look at the updated model, read our Airthings Corentium Home 2 review. It covers the model's display, app connection and added sensors in more detail.

Which one is easiest to use around the house?

All 3 run on batteries, so you can place them without needing a nearby outlet. The Corentium Home 223 is explicitly described as portable between rooms; Wave Radon and Home 2 are also described as battery powered and suitable for home placement.

Wave Radon is 4.7 in wide and 4.7 in high. Corentium Home 223 is 2.7 in wide and 4.7 in high, while Corentium Home 2 is 2.4 in wide and 4.45 in high.

Those measurements can help you plan a spot, but location matters more than choosing the smallest case. Place a detector where you want to understand radon levels, and follow its instructions for setup and moving it.

If you're considering a basement, read our guide to radon levels in basements. Room location and conditions can affect readings, so compare results over time rather than drawing a conclusion from one short reading.

Which detector makes sense for ongoing monitoring?

Choose a model you can check consistently, since radon levels can change over time. Airthings describes continuous or long-term monitoring for all 3 devices.

Wave Radon is designed for year-round monitoring, with daily, weekly, monthly and yearly measurements available in its app. The brand says its long- and short-term averages help you understand exposure over time.

Corentium Home 223 shows short- and long-term readings on screen and can help you check whether changes have affected readings. Corentium Home 2 also supports continuous monitoring, with app graphs that show how radon rises and falls.

A detector doesn't replace steps recommended by local health authorities if readings are high. For broader context about seasonal changes, see what time of year radon is highest.

Do you need app access or remote monitoring?

Bluetooth app access is available on Wave Radon and Corentium Home 2, but remote monitoring needs an Airthings Hub or View series monitor. The original Corentium Home 223 focuses on readings on its own screen.

With Wave Radon or Home 2, Bluetooth lets you sync results to the Airthings app when your phone is nearby. The app can display averages and trends, and Home 2 includes graphs and personalized tips.

For remote monitoring, pairing either compatible detector with an Airthings Hub or View series monitor enables 24/7 access and notifications, according to Airthings. That added equipment is only relevant if you want to check data while away from home.

If you want a simpler routine and don't need app graphs, the original Corentium Home may be enough. Its on-device screen gives you daily, weekly and long-term averages without app setup.

Which Airthings radon detector should you buy?

Pick Wave Radon for app-based tracking, Corentium Home 223 for straightforward screen readings, or Corentium Home 2 for both plus added sensors. The right choice depends on how you want to check results.

Choose Airthings Wave Radon if you want app access to radon averages and trends, along with humidity and temperature readings. It fits someone who expects to check data on a phone.

Choose Airthings Corentium Home 223 if you want a portable detector with an LCD screen and daily, weekly and long-term averages. It suits a reader who doesn't need Bluetooth connectivity.

Choose Airthings Corentium Home 2 if you want both display and app access, plus humidity and temperature sensors. Its combination of readings and viewing options makes it the broadest fit of the 3.
