Short full-open airing instead of a tilted window
Open the window fully for a few minutes instead of tilting it all day to ventilate properly and avoid mould.

- ⏱ 5–10 min

- ◆ easy
How to do it
- Open the window completely instead of tilting it.
- Air the room for 5–10 minutes. This is the guideline for bedrooms (in the morning), kitchens and bathrooms.
Why it works
With a tilted window, the wall beside it cools down quickly. That can cause condensation and lead to mould.
Variations
- In summer, brief, vigorous airing works better than a permanently tilted window. Only air when it is cooler outside than inside, and close the window afterwards.
