“House burping” inspired by the German practice StoBluften is a quick way to stop mould, damp and musty smells during winter. Instead of leaving windows ajar all day, you open several windows and doors wide for 5 -10 minutes to create a cross-breeze. This flushes out moisture-heavy air without cooling down your home. Doing it once or twice a day, especially after showers, cooking, or drying clothes indoors, can help prevent condensation and keep your home fresh and cosy.
