I’ve tested a number of air quality monitors, but none have been as far-reaching as the Caeli monitor from uHoo, which debuted at CES 2026 with all-new features. (If you want to see the tech we can’t stop talking about, check out our Best of CES awards.)
Caeli is a highly ambitious monitor that aims to track nine different aspects of your indoor air, including dust, temperature, VOCs, carbon dioxide and humidity. As you can imagine, it’s larger than most and packed with sensors, plus Matter support for Apple, Google and Alexa.
At CES, uHoo presented a new feature that I’m especially interested in. Caeli will now come with an influenza index, which combines all that sensor data into an analysis, which uHoo reports is based on decades of virology research. For you and me, it comes out as a 1 to 10 score on Caeli that shows the risk of catching the flu or any other virus spreading around.
