A family can generate 10 litres of water each day
All air contains moisture, most of which we contribute ourselves by simply going about our daily lives. A family of two adults and two children, for example, can add between 7 and 10 litres of water a day; however, outdoor air also contains a great deal of moisture depending on the season, weather and where in the country you live.
Normal sources of increased indoor humidity:
• human and animal exhalation
• washing-up, laundry, showers and other wet cleaning
• evaporation from plants and aquariums
• humidifiers, moisture-generating machinery
• leaks and damp
If damp air is not ventilated it can create moisture problems; for example, through condensation on windows or other cooler surfaces in the home leading to damage from damp and mould.
Signs of poor ventilation
In order to avoid issues with damp, it is especially important to maintain good ventilation in wet rooms and bedrooms.
