Targets
- 40–55% RH indoors; below ~35% = dry skin/throat, above ~60% = mould risk.
Tools
- A simple hygrometer in bedroom and living area.
- Optional: small humidifier if RH very low for days.
Do this first
- Seal drafts; warm air holds moisture better.
- Vent bathrooms/kitchen longer (15–20 min).
- Dry clothes with door closed + window ajar or dehumidifier.
Using a humidifier
- Distilled water if possible; empty nightly; clean weekly with vinegar.
- Keep away from walls/furniture; aim to the centre of the room.
Condensation fixes
- Keep furniture slightly off external walls.
- Wipe and dry window sills daily in cold snaps.
