Humidity is a key factor in your overall comfort. When the air is less humid; you feel more comfortable. And that comfort level occurs at a higher temperature; which means you can set your air conditioner thermostat higher and save on energy costs. A dehumidifier also helps prevent damage to walls and foundations from excess moisture. Wood furniture; fabrics and carpets will last longer and smell better with proper humidity. Many electronic devices operate best in a controlled environment. And finally; maintaining proper humidity helps reduce allergens.
