A dehumidifier is frequently necessary during Wisconsin’s typically humid summers to prevent mold and mildew in basements.
What to buy
- ENERGY STAR® certified units are more efficient.
- A larger capacity (more pints per day) is generally more efficient.
- A higher energy factor* is more efficient.
*Rated by liters of water removed per kWh of electricity used.
How to use
- 50% relative humidity is recommended in summer.
- Lower than 50% will use more energy without adding benefit.
- Use a digital humidity gauge to check the humidity level.
- Clean dust and dirt from coils and fan regularly.
Cost to use
- About 6¢ to 10¢ per hour of operation.
- $15 to $35 per month in summer is common.
- Can exceed $50 per month if the dehumidifier runs a lot.
