In many UK homes, a single well-placed twenty litre dehumidifier can control humidity across multiple rooms. The key is airflow and door positioning.
When one unit is enough
- Homes with open landings or central hallways.
- Properties with good internal airflow.
- Flats and smaller houses.
When you may need more than one
- Large homes with closed-off rooms.
- Homes with persistent damp or mould patches.
- Unheated rooms or outbuildings.
Best placement for whole-house drying
Place the dehumidifier on the landing or central hallway. Keep doors open and run the unit for one to three hours per day.
Many households are surprised how well one quality unit can stabilise the entire home.
