3 Ways to Cut Your Dehumidifier Energy Bill
- 🌱
Set the target humidity to 50% instead of the lowest setting — lower targets force the compressor to run constantly.
- 💡
Place it in the center of the room with good airflow rather than against a wall for better moisture collection.
- ⚡
Connect a drain hose to a floor drain so the unit never shuts off due to a full tank.
Startup Surge Information
The compressor motor surges to about 1,000–1,500W during startup before settling back to its running wattage.
