Ceiling fans help reduce power bills, allowing homeowners to raise their thermostats 4 degrees with no noticeable reduction in comfort. Sleek contemporary models with expansive blades powered by energy-efficient magnet motors are the trend today. LED lighting has been incorporated in some models, as have ionizers to purify the air. Damp-listed ceiling fans are designed for rooms exposed to moisture, such as bathrooms, laundry rooms and covered patios. Their motors have special sealants for protection. Wet-listed ceiling fans are even more protected and designed for areas exposed to wet weather such as uncovered gazebos and patios. The basic pull-chain models are still available, but more contemporary models now come with handheld remotes.
