As colder weather arrives, homes across the UK are keeping windows closed more often, which can lead to condensation and mould. A ventilation expert has highlighted a simple 15-minute task that can help keep moisture levels under control.
Why moisture builds up in autumn and winter
With days getting wetter and people drying washing indoors, moisture levels in homes can quickly rise. Ruth MacEachern, ventilation expert at EnviroVent, said there is one common mistake that can add litres of moisture into the air.
She explained: “As households spend more time indoors during the colder months, everyday activities such as cooking, showering and even boiling the kettle can cause moisture levels to rise.
“In fact, four people living in a three-bed property could produce up to 112 pints of moisture a week from just breathing, cooking, showering and boiling the kettle.”
The 15-minute rule for extractor fans
Many people run their extractor fan while showering or cooking and switch it off when they finish. But according to MacEachern, this does little to remove moisture. Instead, she advises keeping the fan running for at least 15 minutes after leaving the kitchen or bathroom.
Six extra steps to reduce moisture
MacEachern also recommends six other steps to lower moisture levels in the kitchen and bathroom:
- Cover pots and pans when boiling water
- Avoid opening the dishwasher until it has cooled
- Avoid opening the oven too often when cooking
- Use slightly cooler water to bathe
- Ensure the bathroom door is closed during and after taking a shower or bath
- Avoid leaving the bath filled for too long after use
Drying washing indoors without causing damp
For those without a tumble dryer or outside washing line, drying clothes inside is sometimes unavoidable. MacEachern suggests using the bathroom as a makeshift drying room.
She said: “Try using your bathroom as a makeshift drying room. Use the towel rail to heat the room and turn the extractor fan on to draw out excess moisture. Make sure not to overcrowd the room and leave space between drying racks to boost airflow.
“Not only does this method dry clothes efficiently, but it also avoids the musty smell that can often occur with indoor drying methods.”
