This is the first smart indoor air quality monitor with radon detection, and it picked up TIME's Best Inventions 2019 and a CES 2019 Innovation Award. Radon is odourless and colourless, one of the leading causes of lung cancer in Canadian homes, and especially common in basements. Its levels fluctuate daily, so short tests don't mean much — continuous long-term measurement is what counts, which is what the Wave Plus is built for.

Beyond radon, it tracks six key factors: carbon dioxide (CO2), total VOCs, humidity, temperature, air pressure and radon. You don't need your phone to read it — wave in front of the device and the light ring colour-codes the verdict: green (good), yellow (fair), red (poor). For detail, connect via Bluetooth to the Airthings App or the web Dashboard and generate a free radon report.

It runs on two AA batteries with up to 16 months of battery life over Bluetooth, so there's no plug and you can place it anywhere. It works with Alexa, Google Assistant and IFTTT to trigger ventilation or purifiers. Give the sensors a 7-day settling period before trusting the readings.

3,214 ratings at 4.3 stars, ranked 14th in Indoor Air Quality Meters. If you have a basement, or just want to know how high CO2 climbs once the windows are shut, this is a solid balance of professional-grade and easy to use.
