Indoor Relative Humidity
Indoor humidity levels also provide a good indication of healthy indoor air quality. In general, a relative humidity
level of 45 to 60% is optimum indoors. A humidity level of 50% is recommended to inhibit dust mites, mould, and
bacteria growth. In colder climates, a lower humidity level of 30 to 40% may be preferred to prevent condensation
on windows and other surfaces.
