Will a dehumidifier prevent condensation?

To prevent condensation in the home you need a continuous source of fresh air. Good ventilation of kitchens when washing or drying clothes or cooking is essential along with a source of ventilation in your bathroom to remove moisture from taking a shower or bath.

The vent is not designed to combat condensation alone but will help circulate air when used with other vents or systems. In some buildings bathrooms or toilets do not have windows. However ventilation will be provided usually by mechanical means. It is important that all ventilation systems are used properly.


Unfortunately, due to the British weather the extent of the condensation problem can be so bad that prevention on its own will not solve the problem and you will need to make arrangements to control the condensation in your home.
