  1. Air-conditioning units generate cold air, but fans keep the air moving. This brings in fresh air which fans efficiently distribute throughout a space, making the room breezier and getting rid of indoor pollutants. 
  2. Fans save energy. They run at only 15 - 150 watts per hour, and consume only 1.9 per cent of household energy, whereas air-cons are chief guzzlers at 36.7 per cent.
  3. To avoid a hefty bill, set the air-con at 26 - 27 dec C and turn on the ceiling fan. The room will be filled with cool air and with lower energy consumption.
  4. A larger fan blade moving at low velocity provides you a gentle breeze, while a smaller blade at high velocity generates stronger wind delivery. Also consider number, design, and material of blades when picking out fans.
  5. Fans with four to five blades provide better wind delivery, but there are exceptions - like the three-blade Haiku fans.
  6. The angle of a blade - angular, flat, or curved - determines the wind spread. Flat blades generate wind within the fan diameter, whereas a higher angled blade covers a wider area.
  7. Acrylic blades glide smoothly while spinning, and are much quieter compared to other materials. They also require less maintenance and are suitable for the outdoors.
  8. Clean the blades with a damp cloth or the long nozzle attachment of your vacuum cleaner, sliding it across each blade and the motor housing to remove all dust. Do not pull or bend the blades, or oil the already lubricated motors.
