An air quality monitor can help users take steps to deal with poor air quality, especially for those who are particularly sensitive. The Davis AirLink Air Quality Monitor can be used inside the home or outdoors. It provides real-time Air Quality Index readings and sends them to a phone or computer.

The air quality sensor measures particulates (PM) in the air by size: PM1, PM2.5, and PM10. The air quality meter gives users information as data and as a color-coded graph that is easy to understand. AirLink is one of the best air monitors for home and outdoor air quality concerns.

With Wi-Fi connectivity, you can use the Davis AirLink with or without a Davis weather station or WeatherLink interface!
