Damp, mould and condensation

Common activities that create moisture

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
