About this app

Proper ventilation can prevent mildew. Mold requires a certain minimum moisture to grow. If the humidity maintained by controlled ventilation in an optimal range, so you reduce the likelihood of mold growth dramatically and also create a healthier indoor climate.

If the indoor air through the ventilation dry, damp or humidity stays about the same? This app will answer the question. For indoor temperature, outdoor temperature and humidity, the new humidity is calculated after airing on the dew point. The calculated value is a theoretical nature, but helps to identify a trend. By comparing with the indoor humidity, a ventilation recommendation (from the perspective of humidity) are added.
