When buying a household fan, choose a fan that covers the room, pushing enough air throughout the space. Buy a fan made of quality material and components to reduce noise, maintain stability and decrease maintenance.
When purchasing a ceiling fan, purchase one with a blade span that is enough to push air throughout the room depending on the room's square footage. If the ceilings are low, use a flush mounted fan or a hugger fan to keep the blades from being in the way. For high ceilings, use down rods to ensure the fan cools the room. To be effective, fan blades need to hang at least seven feet above the floor.
Compare the performance of various fan blades to choose which suits your home the best. Fan blades angled between eight and 15 degrees tend to move more air through a space. Blades are made from plastic, metal, cloth, bamboo and various wood types, making some blades heavier than others which can alter fan performance. For convenience, consider a fan with a remote or adjustable fan speed. Some fans have programmable controls that adjust to the temperature of the room or the time of day. Other fans have a programmable timer that switches the fan off after several hours of use to conserve energy.
