House burping

Uncommon card · No. 157468

House burping is a term primarily used in the United States and on social media, for the practice of opening windows for a brief period in a home to exchange stale indoor air with fresh outdoor air. The practice is derived from the German tradition of lüften (lit. "airing"), a long-standing cultural norm of regular natural ventilation. House burping is promoted as a low-cost method to improve indoor air quality, reduce humidity, and limit mold growth, and it gained widespread online attention during the COVID-19 pandemic and in early 2026 through lifestyle media and social platforms such as TikTok.
