In autumn, proper ventilation is crucial to prevent moisture and mold in apartments. The 5-minute rule suggests short, frequent airing sessions to refresh the air and maintain warmth without energy loss. Experts recommend fully opening windows for brief periods several times a day, adjusting the duration based on outdoor temperatures. Continuous airing with slightly open windows can lead to heat loss and increased humidity, promoting mold growth. It's advised to turn off heating during airing and maintain indoor temperatures above 16°C. Regular checks of humidity levels, ideally between 40% and 60%, are also essential to prevent mold-related health issues.
