Airthings View Plus vs Aranet Radon Plus

The Airthings View Plus wins overall by doing more, leading on sensors, connectivity, integrations, alerts and warranty. Both detect radon, but the View Plus adds CO2, PM2.5 and VOCs plus Wi-Fi. The Aranet Radon Plus earns a higher owner rating as a radon specialist, with a much longer battery and an IP20 build.

Focus. The Aranet Radon Plus is a dedicated radon detector (plus temperature, humidity and pressure) with fast 10-minute readings on Bluetooth. The Airthings View Plus measures radon alongside CO2, particulates and VOCs, seven sensors in all, and adds Wi-Fi for remote access.

The Aranet Radon Plus is the stronger radon instrument: it takes a reading every 10 minutes and owners report it matching mail-in lab kits, backed by Aranet's accuracy reputation. The Airthings View Plus tracks radon well as part of a broader picture, but for radon precision alone the specialist Aranet shines.

The Aranet Radon Plus is rated around 7 years on two AA cells, far longer than most monitors. The Airthings View Plus runs about 2 years on AA batteries and can also run on USB-C, trading battery longevity for Wi-Fi and a wider sensor suite.

Choose the Airthings View Plus if you want radon plus a full air-quality picture (CO2, particulates, VOCs) in one Wi-Fi unit with remote access, broad integrations and a 5-year warranty.

Choose the Aranet Radon Plus if radon is your priority and you want the most accurate, lowest-maintenance option: 10-minute readings, a battery rated around 7 years, an e-ink display and Home Assistant support, ideal for a basement or tracking a mitigation system.
