Damp, mould and condensation

Our everyday activities add extra moisture to the air inside our homes:

• even our breathing adds some moisture. One person asleep adds half a pint of water to the air overnight and an active person adds twice that rate during the day. 2 people at home for 16 hours can add 3 pints
• a bath or shower can add 2 pints
• drying clothes indoors can add 9 pints
• cooking and use of a kettle can add 6 pints
• washing dishes can add 2 pints
• a bottled gas heater (8 hours use) can add 4 pints
