Once the windows close for a Canadian winter, radon, CO2 and volatile chemicals (TVOCs) are exactly what builds up indoors — and radon is odourless and invisible, so your nose will never flag it. That's why many homes bring in a unit that can measure radon continuously over the long term.

The Wave Plus is an award-winning model (TIME Best Inventions 2019, CES Innovation Award honouree). One unit tracks six factors: radon, CO2, TVOCs, humidity, temperature and air pressure. Radon fluctuates day to day, so a single reading means nothing — it has to be measured continuously, which is why these units stay plugged in and in place.

Setup is easy: pair over Bluetooth with the Airthings app, or log into the web Dashboard for deeper analytics. Even simpler — wave your hand in front of it and it shows green/yellow/red for overall air quality. You can also pull a free radon report from the Dashboard.

It works with Alexa, Google Assistant and IFTTT for smart-home integration. Power comes from two AA batteries with over a year of battery life in Bluetooth mode, so there's little to manage. At just 218 g it sits on a desk or mounts on a wall.

Honestly, the value here isn't a discount today — it's a one-time purchase that quietly watches something you can't see. If you live in an older home, use the basement often, or recently renovated with kids or seniors around, $299.99 for continuous air readings is something you'll keep using. 4.3 stars, 3,200+ reviews, consistently near the top in air and smoke monitoring.
