In winter, when windows stay shut for hours, humidity becomes one of the biggest threats to home comfort. Condensation on glass, damp walls, and mould growth are all common problems. With a few practical steps and the right equipment, you can keep your home dry and healthy all season long.
Why condensation forms
Condensation appears when humid air meets cold surfaces, usually windows or poorly insulated walls. It's most common in winter, when the inside is heated but the outside stays cold. If excess moisture isn't managed, mould follows. Mould causes unsightly stains, bad smells, and can trigger respiratory problems.
The root causes are often structural, such as poor insulation or thermal bridges, but everyday habits matter too. Cooking without ventilation, drying laundry indoors, or neglecting air conditioning filters all push indoor humidity higher.
Ventilate and dehumidify: the smart approach
Start with airflow. Just 10 minutes of open windows in the morning and evening is enough to fully refresh indoor air without losing much heat. On the coldest days, or in rooms with poor ventilation, a dehumidifier is the most reliable solution.
A portable unit like the Ariston Deos Evo 12 works well across different rooms. It operates quietly and precisely, keeping relative humidity between 40% and 60%, the ideal range for a comfortable, healthy home.
Maintenance and daily prevention
Alongside the dehumidifier, a few habits make a real difference:
- Check problem spots regularly: corners, behind furniture, and external walls for any signs of moisture.
- Clean the filters on your air conditioning or ventilation system to prevent water buildup and bacteria.
- Keep radiators clear of curtains and furniture so heat can circulate freely.
One more tip: use the dehumidification mode on your inverter air conditioner on damp days. It uses far less energy than full heating and makes the air noticeably lighter.
Preventing mould and condensation is about more than clean walls. It means healthy air and consistent comfort. Your home stays dry, welcoming, and protected throughout winter.
