Airthings Wave Mini has four indoor air quality sensors, including mould risk indication to proactively prevent mould. The Wave Mini monitors mould risk, pollen levels, temperature, humidity and airborne chemicals (VOCs) to help with asthma, allergies, sleep and overall health with this battery operated wireless sensor. You can also receive live and local pollen data with the app. When you understand the air quality in your home, you can make small changes to your everyday habits to optimise the health and comfort levels for you and your family. Keep your home and family healthy and safe from mould damage with Wave Mini, because when you can see the mould, it is too late.
