A dehumidifier can make a noticeable difference within hours, but the full effect depends on how damp the home is and where the unit is placed.
Typical results
- First two hours: humidity drops and windows dry.
- First day: rooms feel fresher and lighter.
- One week: mould smells fade and condensation reduces dramatically.
Factors that affect speed
- Room temperature.
- How much moisture is in the air.
- The size and power of the dehumidifier.
- Placement and airflow.
Most modern units work fast when used correctly, especially twenty litre models.
