Thread and Bluetooth connectivity enable a quick and direct to HomeKit connection without a hub.

Cost effective: Aqara Indoor Air Quality Monitor, Requires AQARA 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.

All-in-one: Qingping Air Monitor Lite, Apple HomeKit Compatible Wi-Fi Indoor Air Quality Meter
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.

Inside and out: Netatmo Weather Station Indoor Outdoor with Wireless Outdoor Sensor
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.

Monitors and cleans: Smartmi Air Purifiers for Home
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.

Smoke and CO: First Alert Onelink Safe & Sound
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.
Monitor the situation with the best HomeKit air quality sensors
The best HomeKit air quality sensors are the quiet protectors of your home, silently measuring for dust, pollen, VOCs, CO2, and more. Once your device is up and running, it can work with tons of HomeKit accessories such as smart plugs that can turn on an air purifier if the air in your home becomes an issue. Siri support allows you to summon a brief report, with the virtual assistant replying with easy-to-understand responses such as "good" or "bad."
We love the Eve Room for its beautiful design and its portability. This fantastic monitor includes an E Ink display with customization options to make the metric that matters the most to you at the forefront. This sensor also features a built-in rechargeable battery that lasts up to six weeks, and it supports Thread — the latest and greatest connectivity standard.
