Humidity tips

Even on warm days, people add CO2 and moisture indoors. Use short, targeted ventilation when the room starts to feel stale.

Keep your home cool without letting it turn stuffy: during heat, ventilate briefly when humidity or CO2 starts to build up.

Damp towels can help on hot days, but only with airflow and humidity control. If the room feels humid, ventilate briefly even during the day.
