Our take
The Haiku L is the gold standard for ceiling-fan efficiency. Its proprietary DC motor and airfoil-shaped blades move a lot of air for remarkably few watts, which is why it consistently tops ENERGY STAR's CFM-per-watt rankings. It offers 7 speeds, a 16-setting dimmable integrated LED, Wi-Fi app and voice control (Alexa/Google), and optional SenseME automation that turns the fan on/off based on occupancy and temperature. The catch is the price, which is several times that of a conventional fan, and a 52-inch span that suits a single large room rather than a whole house. For shoppers who care most about minimizing energy use and noise, nothing else on Amazon matches it.
What we like
- Class-leading airflow efficiency (top ENERGY STAR CFM/watt) from its DC motor
- Extremely quiet at all 7 speeds
- Smart automation (occupancy/temperature sensing, schedules, app and voice control)
- Dimmable 16-setting integrated LED with a sleek, low-profile design
What to keep in mind
- Very expensive compared to typical ceiling fans
- Wi-Fi/app setup can be finicky and ties some features to the cloud
