The Airthings Wave Mini air quality monitor measures the total concentration of volatile organic compounds (TVOC), temperature, and humidity indoors. The Mini visually displays air quality with colors, and the user-friendly app provides very accurate additional information about the measurements. The Wave Mini also supports the Airthings Hub accessory.

The Mini features a mold risk assessment. Although the device cannot directly detect mold, it can provide an estimate of mold growth risk when installed correctly. This estimate is based on an algorithm that utilizes temperature and humidity. More information about this feature is available in English.

In April 2021, pollen information was added as a new feature in the app. This information comes from an external source, meaning that the device itself does not measure pollen levels. With the pollen information, you will know when to close windows or use an air purifier or air conditioning.
