Dehumidifiers
For fresh air and energy savings, purchase an energy-efficient dehumidifier. The average ENERGY STAR® dehumidifier can save up to $175 over the life of the unit.
ENERGY STAR certified dehumidifiers have more efficient refrigeration coils, compressors, and fans, compared to conventional models, which means they use less energy to remove moisture.

How to choose the right size dehumidifier
A dehumidifier pulls moisture from the air, helping to reduce humidity and improve the quality of air, but it should be properly sized for the needs of your home. A dehumidifier that is too large will waste energy and lead to higher electricity bills. Bigger isn’t always better. The size you'll need depends on the size of your room (or basement) and the amount of moisture present in the air. Use the chart below to estimate the capacity you are looking for;
| Size in pints per 24 hours | ||||
| Dampness | 500 sq. ft. area | 1000 sq. ft. area | 1500 sq. ft. area | 2000 sq. ft. area |
|---|---|---|---|---|
| Moderately Damp - space feels damp and smells musty only in warm, humid weather. | 10 pints | 14 pints | 18 pints | 22 pints |
| Very Damp - space always feels damp and smells musty. | 12 pints | 17 pints | 22 pints | 27 pints |
| Wet - feels and smells wet. Seepage occurs. Mold and mildew growing on surface. | 14 pints | 20 pints | 26 pints | 32 pints |
Other ways to reduce humidity in your home
- Keep basement and crawl spaces sealed off from the outdoors.
- Install gutters and divert roof runoff away from the foundation.
- Improve grades around the foundation to drain water away.
- Cover dirt floors in crawl spaces and basements with heavy-duty plastic.
- Ensure that clothes dryers are properly vented to the outdoors.
- Wrap cold water pipes with pipe insulation to eliminate sweating.
- Use exhaust ventilation to remove moisture generated by showering, bathing, and cooking.
- Reduce the number of plants in humid areas.
- Do not store wet firewood in the basement.
- Do not open basement windows and doors in the summer to dry out the basement. This can make the problem worse by allowing moist outdoor air into your cool basement, causing increased condensation.
