I tested a number of them air quality monitorsbut none have been as ambitious as uHoo’s Caeli monitor, 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 very 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, as well as Matter support for Apple, Google, and Alexa.
At CES, uHoo presented a new feature that I’m particularly interested in. Caeli will now feature a Flu Index, which combines all sensor data into an analysis that uHoo says is based on decades of virology research. For you and me, this translates to a score of 1 to 10 on Caeli which shows the risk of catching the flu or any other virus that is spreading.

Caeli tracks a lot, so virus and mold indexes can save time.
uHooA score of 1 to 3 is good, indicating a low risk of spreading viruses through the air. However, as humidity increases, temperatures rise, and particles in the air increase, the flu index can also increase, with a score of 10 being the worst, indicating the highest likelihood of getting sick.
If the score starts to get closer to 10, you can throw out any members of your family who are sick and lock the door to prevent infections. Or maybe you should light up an air purifier And dehumidifier and ask your sick loved ones to mask up instead.
Caeli will also include a Mold Index that shows the danger of mold spores spreading, another important risk to watch for in a home, especially if you live in a humid climate. Additionally, CO/CO2 monitors benefit overall health even when no one has symptoms, and particle counting is also helpful during allergy season.
The Caeli Monitor is scheduled for release in February. You can pre-order it now for $200 (an admittedly steep price for an air monitor), but the cost will increase later. Or you can wait until CNET gets its hands on a model to test all these sensors and see how they perform.
