• Mute Design: Adopting low-noise motors and optimized fan blade structures, the noise during operation is small (mostly 30-50 decibels), suitable for places that need quietness such as offices and libraries.
• Additional Functions: Some fans integrate practical designs such as small night lights, aromatherapy boxes, and mobile phone holders to enhance the user experience.
