Mould is an unwelcome guest in any home. It’s not only unsightly, but it can also pose serious health risks if left unchecked. Despite trying conventional methods like vinegar and mould sprays, getting rid of it can feel like an uphill battle. But there’s a simple and effective German technique called ‘Stosslüften’ that costs nothing and can help keep your home mould-free.
Many believe opening windows in winter is a bad idea due to the cold, but ‘Stosslüften’ challenges this notion. This technique involves opening multiple windows across your home for a brief period, creating a strong draft that rapidly exchanges the humid indoor air with drier cold air. The logic behind this is that cold air holds less moisture than warm air. When cold air enters your home, it warms up and becomes capable of absorbing some of the excess humidity from the inside.
This seemingly simple method has been advocated in German schools and is widely practiced by many. A Reddit user explained the concept, stating that instead of leaving a single window open all day (which wastes energy), opening several windows for just three minutes creates a powerful draft, effectively clearing out the humid air. They emphasized that doing this several times a day can drastically improve the humidity levels in your home.
Raymond Galvin, a researcher at the University of Aachen and Cambridge, supports this method, stating that it’s the most effective way to ventilate a home. He recommends opening windows completely for three minutes in windy conditions and five to ten minutes if it’s calm.
The positive feedback on social media reflects the effectiveness of this simple yet powerful technique. TikTok users have shared their experiences, with one stating they practice ‘Stosslüften’ every morning for fresh air, regardless of the temperature. Another user commented that they keep their back door open all the time. The consensus is clear – ‘Stosslüften’ is a game-changer for maintaining a healthy and mould-free home.
So next time you’re battling mould or looking to improve the air quality in your home, try the German ‘Shock Ventilation’ technique. It’s an energy-efficient, cost-effective solution that could make a world of difference.
