Airthings 325 Corentium Home 2 vs Airthings View Plus

The Airthings View Plus wins overall, taking connectivity, sensors and alerts. It combines radon with PM2.5, CO2, VOCs, temperature, humidity and pressure, adds Wi-Fi for remote access, and has a fuller alert set. The Airthings 325 Corentium Home 2 counters with a lower price, a higher owner rating and longer battery life, but it only monitors radon, temperature and humidity.

Breadth of sensing and connectivity. The Airthings View Plus is a seven-sensor, Wi-Fi monitor that measures radon plus PM2.5, CO2, VOCs and more for remote, whole-air-quality tracking. The Airthings 325 Corentium Home 2 is a dedicated Bluetooth radon monitor covering radon, temperature and humidity, meant to be checked from the app nearby.

No. The Airthings 325 Corentium Home 2 measures radon, temperature and humidity only. The Airthings View Plus adds CO2, VOCs and PM2.5 particulate sensing (seven sensors in total), which is why it is the choice for people who want a complete picture of indoor air quality rather than radon alone.

The Airthings View Plus adds Wi-Fi on top of Bluetooth for remote access and alerts, and runs about two years on AA batteries. The Airthings 325 Corentium Home 2 is Bluetooth-only (so you check it from the app when nearby) but its AA batteries last around three years, a bit longer than the View Plus.

Buy the Airthings View Plus if you want one device that monitors radon, CO2, VOCs and particulates with Wi-Fi remote access, a display and a strong app or web dashboard. It suits serious indoor air quality tracking and whole-home setups with a unit per floor.

Buy the Airthings 325 Corentium Home 2 if radon is all you need to track and you want a cheaper, well-rated monitor with a simple display and long battery life. It is ideal for basements and radon-prone areas where you check readings from the app nearby rather than remotely.
