Freshening the air is not deodorising with scented candles and deploying half a bottle of Febreze to mask a musty, damp issue. This depends primarily on consistent, good housekeeping, promoting a controlled ingress of fresh air, and steadily expelling stale air. Most of us are not enjoying the silent, automated magic of whole-house mechanical ventilation (with heat recovery if you’re very lucky). Still, air exchanges from outdoors are at the heart of a healthy home with good indoor air quality (IAQ). If you are relying solely on trickle vents in the windows, these should not be taped or set to shut.
