Best HomeKit air quality sensors 2022

Eve's indoor air quality monitor features an industrial design complete with an E Ink display. This portable monitor lasts up to six weeks on a single charge, and it also includes temperature and humidity monitoring. Thread and Bluetooth connectivity enable a quick and direct to HomeKit connection without a hub.

While it requires an Aqara hub, the Aqara TVOC Air Quality Monitor is still an incredible value with an E Ink display that impressed us in our recent review. Aqara's sensor monitors VOCs, temperature, and humidity in an incredibly compact frame that runs for up to a year on a coin battery.

This sensor from Qingping is not only an air quality monitor but it also serves as a digital clock, making it perfect for bedrooms. An on-device OLED display scrolls through the current time and measurements for CO2, temperature, humidity, PM 2.5, and PM10. This sensor even includes a rechargeable battery so you can take it from room to room.

The Netatmo Smart Weather Station is the only HomeKit air quality sensor that can monitor air quality inside and out. This two-piece set includes an indoor module that tracks CO2, temperature, and humidity and a weatherproof outdoor monitor that gives you a local weather report.

The Smartmi P1 is one of the few HomeKit-enabled air purifiers on the market, but it includes many extras to match the price. In our hands-on review, we loved how this purifier monitors your home and automatically ramps up fan speeds to clean quickly if the quality drops. Smartmi's cleaner also puts all of its measurements and speeds just a glance away thanks to its on-device display.

The First Alert OneLink Safe and Sound may look like an ordinary smoke and CO detector, but it has an AirPlay 2 compatible speaker for whole-home audio. Of course, this monitor also includes smoke and CO detection with a built-in alarm, and both are capable of sending notifications to your iOS devices when something is awry.
