ENERGY STAR certified models have more efficient refrigeration coils, compressors, and fans than conventional models, which means they use less energy to remove moisture.
An ENERGY STAR certified dehumidifier removes the same amount of moisture as a similarly-sized conventional unit, but uses 15% less energy. In fact, the annual energy saved by an ENERGY STAR qualified dehumidifier could power your ENERGY STAR qualified refrigerator for 4 months!
Current Specification Effective Date: October 1, 2012
Dehumidifiers originally qualified for the ENERGY STAR label in January, 2001. Dehumidifiers that have earned the ENERGY STAR are 15% more efficient than non-qualified models.
What else should I look for when buying a dehumidifier?
In addition to energy performance, there are many other important operating and convenience features to consider when shopping for dehumidifiers
- Water Removal Options
- Operating Temperature
- Relative Humidity (RH) and Humidistats
- Energy Factor
Other Ways to Reduce Home Humidity
Reducing sources of moisture can reduce your need for dehumidification.
Improving the drainage around the foundation of your home may result in decreased humidity in your basement. Some ways to improve drainage are:
- Extend downspouts from your gutters away from the foundation of your home
- Keep gutters and downspouts clear and open
- Ensure that the soil slopes away from your foundation, to avoid pooling of water around your home
- Avoid over-watering of foundation plantings
Ensure that clothes dryers are properly vented to the outdoors. If you do not use a clothes dryer, dry your clothes outdoors as opposed to hanging them inside for drying.
Use vent fans in bathrooms and kitchens to remove humidity at the source.
Repair leaking outdoor faucets. Not only will this help reduce humidity, but it will also save you money on your water bills!
If your home uses central air conditioning, consider installing an A/C vent in the humid space in your home and take advantage of the dehumidifying capabilities of your A/C system. This will also help with air circulation, improving airflow between humid parts of your home and drier parts.
