Airthings Wave Mini Indoor Air Quality Monitor review
A damp-prone bathroom, utility room or bedroom where humidity and airborne chemicals are the actual question.
By Tom Calder · Price last checked 20 Sep 2026, 12:29 BST · price-tracked
This is a VOC-and-damp device rather than an air quality monitor in the general sense: no radon, no CO2, no particulates and emphatically no carbon monoxide. Its Mould Risk Indicator is a 0–10 score calculated from temperature and humidity, not a measurement of mould or spores. At around £75 it is the cheapest way into the Airthings app, but you are paying close to Aranet4 money for considerably less sensing.
