Ceiling fan

Pros

  • A ceiling fan is quieter than a portable fan. The bigger blades move the same amount of air with a slower rotation.
  • A cleaner look, integrated in the room, compared to desk fans.
    Because it’s raised of the floor, cleaning your desk or floor doesn’t become harder.
  • Save money on air conditioning in the summer
    • research claims 15% AC reduction
    • research claims Elevated air movement reduced cooling energy requirements by 32%.
    • research claims higher fan speeds don’t increase AC savings

Cons

  • Always visible even when not in use. Increasing visual noise and clutter, takes up desk space, and gathers dust.
  • More costly to install than a table fan.

blade count

Adding more blades (and keeping the same solidity ratio) reduces this noise while maintaining the same air flow.
