How to use this result
Airflow is useful when it removes stale or damp air without making the bed uncomfortable. The right answer can be a small pre-bed ventilation window, not leaving the room open all night.
This planner balances condensation, noise and draughts. It is especially helpful in bedrooms where the morning window tells a different story from the evening thermometer.
Change one setting for two nights before deciding it works.
Best use
Run the tool, choose one change, repeat it for two or three nights, then compare the room notes. A repeated pattern is more useful than one perfect-looking number.
