Airthings View Plus vs Aranet Radon Plus

The Airthings View Plus wins overall by doing more, leading on sensors, connectivity, integrations and warranty. Both detect radon, but the Airthings View Plus adds CO2, PM2.5 and VOCs plus Wi-Fi. The Aranet Radon Plus is the radon specialist, with the stronger owner feedback, a much longer battery and a two-year warranty instead of five.

Focus. The Aranet Radon Plus is a dedicated radon detector plus temperature, humidity and pressure, with fast 10-minute readings over 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 Aranet is the specialist.

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

Buyers who want radon plus a full air-quality picture, including CO2, particulates and VOCs, in one Wi-Fi unit with remote access, broad integrations and a five-year warranty.

Buyers whose priority is accurate, low-maintenance radon: 10-minute readings, a battery rated around seven years, an e-ink display and Home Assistant support, ideal for a basement or tracking a mitigation system.
