Tips About Key Comparison Points:
NOTE: Performance data is as reported by the manufacturer on HIGH SPEED!
On a scale from 1 to 5 where 5 is the best quality. Any fan on our site that has a quality rating of 4 or 5 will run smooth and quiet without wobble or noise and will have the most durability. Fans rated 5 are exceptionally better in all aspects of construction and are considered the best of the best. We generally do not recommend any ceiling fans that have a quality rating less than 3.
CFM is the Cubic Feet per Minute of airflow that a ceiling fan is capable of generating on high speed. The EPA now requires all ceiling fan manufacturers to publish this information for consumers to use as a comparison tool while shopping for ceiling fans.
Wind Speed Factor - Wind Speed is King!
Because ceiling fans cool you off by creating a wind-chill effect, the higher the Wind Speed is the cooler you will feel. How much air a fan moves (in CFM) does not tell you how fast that air is actually moving relative to the size of the fan. Our Wind Speed Factor takes into account how "diluted" the breeze is based on the area the fan covers (blade span). Larger fans may be capable of moving a higher volume of air (measured in CFM), but they tend to do it more slowly (measured in MPH). Comparing how fast the air actually moves gives you a much better way of knowing which fans will actually cool you off the best. This is critical information when considering whether to use one large fan or two smaller fans in a large area. In most cases, 2 smaller fans will provide the best cooling effect. Calculating the Wind Speed Factor is an exclusive feature of our website...meaning, no other website provides this helpful information.
Watts on High
This is the amount of electricity that each ceiling fan uses on high speed. This is not nearly as critical as CFM or Wind Speed because even the highest wattage will cost less than 1 penny per hour to operate. So CFM and Wind Speed are far more important that wattage.
Efficiency is defined by the EPA as CFM/Watt or "The Cubic Feet Per Minute of Airflow per Watt of Electricity used". Efficiency is still less important than CFM or Wind Speed because a fan can be super efficient without moving much air, which means it will actually be a waste of electricity if it does not cool you off. Efficiency can certainly be the deciding factor when considering fans that produce similar airflow.
