Based on its readings, you can adjust your heating or open a window to reduce humidity or air pollution. Improve air quality in additional rooms As we spend much more time indoors than out, it’s important to think about the air we breathe inside our homes, depending on how we use each room. For example, a poorly ventilated bedroom fills with CO2 at night, leaving you tired when you wake up. The Additional Indoor Module provides real-time air-quality readings for your chosen rooms. Right, it’s time to open some windows!
