The Online Guide to Comparing Ceiling Fans
As of January 1, 2009, all ceiling fan manufacturers are required to test their ceiling fans for performance and publish the results to the public.
With this new legislation, you can now determine which ceiling fans are best for your needs...that is, if you know how to interpret the data.
Hansen Wholesale is the first website to compile this information and display it in a graph format that allows you to easily compare the performance of each ceiling fan as you browse our site!
In each graph you will see how much air each fan moves in CFMs (Cubic Feet per Minute of Airflow), how much electricity they use in Watts and how efficient they are in terms of CFMs per Watt.
We have also added our own Quality Rating to help you decide which fans are best.
Look for these Comparison Graphs as you browse our site!
Important Note: "AVG" marks where the average fan is rated so you can easily determine if a fan is above or below average for any of the 4 ratings.
Look for fans with "Above Average" Quality, CFM and Efficiency ratings and "Below Average" Watts (LESS watts is better).
How to interpret the ceiling fan Comparison Graphs
Each graph contains 4 criteria for comparing ceiling fans. They are:
- Quality
- CFM Airflow
- EPA Efficiency
- Watts of Electricity Used
Which cieling fans are the best? The best fans are those with the highest Quality, CFM, and Efficiency ratings...but with the lowest Watts!
Averages: Notice that in each graph there is an "Ave" with black arrows on either side. This is a demarcation of where the average ceiling fan would be for each of the 4 criteria.
Better fans will be above this mark. However, some of the best fans may in fact be far above average for Quality and CFM, but may be below average for Efficiency and Wattage.
This is because some of the higher quality fans that move lots of air tend to have larger more powerful motors that use a bit more electricity. Not to worry...these are still
great choices.
Here is a brief explanation of each of the criteria
Quality: This is a rating of from 1 to 5 where 5 represents the best quality fans on the market.
This rating is determined exclusively by our own ceiling fan experts on staff and is based on our first hand knowledge of each fan.
The quality rating has nothing to do with how much air a fan will move, that is a separate rating. Quality has to do with how well the fan is made, how smooth and quiet it will operate, how long it will last, and equally important...how good looks in real life. The internal components use to make the fan including the motor, capacitors and controls are considered for the precision and tolerances to which they are made are critical. We highly recommend any ceiling fan that has a Quality rating of 4 or 5 when considering the other criteria below.
CFM Airflow: CFM is short for Cubic Feet per Minute, which is how the airflow of a ceiling fan is measured. The CFMs shown in each graph represent the volume of air the fan can move when it is on High Speed. Aside from Quality, CFM is by far the most important piece of information to compare between ceiling fans. Simply put, the more CFMs the fan can produce, the cooler it will make you feel...and since most people buy ceiling fans in order to stay cooler, you must make sure you get sufficient airflow, otherwise you may be dissatisfied with your ceiling fan regardless how smooth and quiet it performs or how great it looks in your room. Based on comparing over 1200 ceiling fans that we have data for on our site, the average ceiling fan moves about 5755 CFM. The worst is around 1400 CFM and the very best is just a little over 10,000 CFM. So there is quite a range of difference in the performance between ceiling fans. For average size rooms, we recommend ceiling fans that are capable of moving at least 6300 CFM, which is slightly above average. Larger rooms will need much more and smaller rooms can get away with less.
Efficiency: Efficiency is defined by the EPA as CFM/Watts. This translates into the amount of air a fan moves (in CFM) divided by the amount of electricity it uses (in Watts) at high speed. Normally you would think of efficiency as a number between 1 and 100 because no mechanical device can actually be more than 100% efficient. However, the formula adopted by the EPA is actually a rather good way to compare the cost to operate a fan -vs- the comfort level you can expect from it to create. However, the most efficient ceiling fan will only save you about $10 to $20 per year max compared to the worst fan because even the worst fans use less electricity per hour than a single 100 watt light bulb. So it is our opinion that the CFM rating is far more important than the efficiency rating because a fan that produces more airflow is going to allow you to raise your thermostat 2 or 3 times higher than one that blows less air. That alone can save you hundreds of dollars per year. So don't sell yourself short by using the efficiency rating as the first criteria to consider. If you are torn between 2 models, then you may want to use it as a deciding factor. The best choice would be a fan with both a high CFM rating and a High Efficiency rating...although there are few that meet that criteria since getting the most air generally entails using more power.
Watts of Electricity Used: This is the amount of electricity that you can expect the ceiling fan to use when operated on the highest speed. Watts is the only criteria in the graph that should be "LOWER" not higher, since the less Watts a fan uses, the less it costs to operate. Although this number is used to calculate the efficiency of the fan, it can also be used as a direct comparison between fans, or simply to get a better grasp on how much energy a fan will use. Think of the wattage in terms of light bulbs and you will easily understand just how little electricity virtually all ceiling fans use. This is the main reason that ceiling fans are such a popular alternative to air conditioning...simply because they use less electricity than an average light bulb. Use the calculator below to see just how much any of our fans will cost you to operate based on the Watts it uses.
Calculate how much it will cost to operate a ceiling fan based on the Watts it uses
If you look at your last electric bill, it will tell you just how much you are paying for each kWh of electricity (Kilowatts per hour).
You can use that number to calculate the actual cost of operating any of the ceiling fans on our site that have the Watts data.
Just plug in the Watts the ceiling fan uses and your own kWh cost...or select your state to automatically input an estimated average.
The average kWh by state used by our calculator is derived from information published by the
US Government Department of Energy as of May 2009.
Since this is an average number calculated by the Government, your actual cost may differ from this. You can find your exact cost of electricity per kWh on your electric bill
if you wish to plug in that number for a more precise calculation.
EPA Exemptions for CFM Testing
Certain ceiling fans are exempt from the EPA legislation, particularly hugger fans and fans with large palm leaves. Apparently hugger fans cannot be tested using the same method...and they do not move as much air as traditional fans anyway. Fans that are considered as strictly decorative are exempt as well such as fans with palm leaf blades, belt driven fans, and Punkah style fans that waft from side to side. Fans like these are simply not capable of moving much air and should only be considered where you are more interested in making a decorative statement and do not really care about keeping cool or lowering your thermostat.
More information regarding what to look for in ceiling fans
Important Note: The information below has been posted on our website for several years...which was prior to having the CFM and Watt data as detailed above. We have kept this information on our site for you to review because most of it is still pertinent, although some details make less sense now that there is actual data that can be used to compare fans.
The most common mistake people make when purchasing a ceiling fan is to base their decision strictly on how a fan looks and how much it costs without considering how it will perform. Will it wobble? Will it make noise? Will it actually cool you off? After talking to thousands of people shopping for ceiling fans over the past 20 years, I have learned that the average consumer is not even aware that there are such differences between ceiling fans. They generally assume that one fan is more expensive than another simply because it is fancier...or it has a remote control or some other feature.
The bottom line is, there are huge differences in the performance and quality of ceiling fans that you need to be aware of...and the information on this page will help you understand them
The most important component of a ceiling fan is the motor.
If you have ever shopped for a car, you know some cars are available with your choice of a 4 cylinder, 6 cylinder, V8 and or high performance V8. You also know that the price goes up substantially with each motor as does the performance capabilities and optional bells and whistles. In general, the same is true for ceiling fans. The motor inside each ceiling fan is the most important component to compare because it is what makes the fan work. Smaller cheaper motors move less air and are not precision made so they have the propensity to wobble or make noise. Larger high performance motors have precision made components designed to provide maximum air movement with smooth quiet operation, but they come at a much higher price. Just as with shopping for a car, you will need to balance the quality and performance level with your budget.
Unfortunately, the motor inside a ceiling fan is completely hidden inside the decorative outer casing, so you don't necessarily get to "Pop the Hood" before you buy a fan. But, if you know what to look for, you can make an educated decision when comparing ceiling fans...which is why we have made it easy for you by including this information in our search result pages and on our product detail pages.
Although there are many more motors used in ceiling fans than what we have here in this chart, this information will give you a good idea as to how we go about rating our fans. In most cases, the rating we give a fan is directly related to the motor inside. However, equally considered is the quality of the additional components used to make up the fan. The best fans will have precision made components throughout so they will run smooth and quiet and last a lifetime.

Important
Note:
Fans with extra wide palm leaf, wicker, or canvas type blades will
only provide a gentle breeze and are considered to be more decorative than
functional. Because this type of blade will tend to overwork an average
fan motor we recommend that you choose only brands that offer these styles
with Hi-Performance motors. Otherwise, your fan will overheat and start to
make annoying noises and eventually burn out. (There is more this in the
details below)
DETAILS: What makes
some fans better than others?
The motor inside your
fan is the most important component!
The most important
consideration when purchasing a fan (aside from the way it looks) is the
size, power, and durability of the motor. Larger more powerful motors are more expensive than smaller more generic mass
produced motors...but they will move substantially more air without wobbling or making noise and can be left
running for days, weeks, even years on end without burning out.
There are 5 major factors
that work together to determine how much air a fan will move as well as
it's overall performance and durability. The most important factor is the
motor. A strong precision made motor will move the most air without noise
or wobble if the other 4 factors are present.
The 5 basic factors are:
-
Blade Pitch
-
Blade Shape and Size
-
RPM
-
Height from Ceiling
-
Motor
Looking more closely at
each of these factors will show how they affect each other and why a fan
with the most powerful motor can produce the most
air movement.
-
Blade Pitch:
The angle at which the blade sweeps through the air is called the
"Pitch" of the blade. The easiest way to understand how
blade pitch effects air movement is to equate the blades of a fan to the oars of a rowboat. If
you have ever tried to row a boat, you know that if you put the
oars in the water virtually flat, it takes very little effort to
row...but even if you row very fast, the boat moves very slow. If, on
the other hand, you tilt the oars at a steep angle in the water, it
becomes very difficult to row the boat...but each stroke makes
substantial progress. You will need to be much stronger and in better
shape to sustain a high rate of speed for any period of time in this
case.
The same is true with ceiling fans. Believe it or not, a fan spinning
at a high RPM encounters substantial wind resistance if the blades are
set at a steeper pitch. A fan that has blades with a very
flat pitch (between 10 and 12 degrees), does not require a very
powerful motor to make the blades spin fast. However, even at full
speed, the fan will move very little air and may have a tendency to
wobble or make noise.
On the other hand, a good blade pitch (between 14 and 15 degrees) requires a well
engineered finely tuned powerful motor to move the blades through the
air at a high rate of speed for extended periods of time without
overheating and burning out.
Just as well, a good blade pitch with an average or lower grade motor
will not be able to reach as high an RPM and may in fact be overworked
resulting in a fan that overheats and eventually burns out.
Therefore, the pitch of the blade and the power of the motor must be
well engineered to work together to create air movement without going
beyond the motors capability in order for a fan to operate efficiently
and last a lifetime.
-
Blade Shape and
Size
Imagine rowing a boat with short narrow oars compared to wider longer
oars. The wider and longer the oar is, the more effort it takes to pull it
through the water. But once again, more effort means more progress.
With ceiling fans, when you combine a wider longer blade with a steeper
pitch, you get even more air movement...at least to a certain point.
There is a limit to the shape and size that the oars or fan
blades can and should be. If the oars or blades are too wide or too
long, you will
not be able to move maneuver them fast enough no matter how
strong you are. As with ceiling fans, blades that are too wide or long
cannot be moved fast enough to be effective with even the most
powerful fan motor. So...larger does not always mean better...but too
small or narrow is not good.
-
RPM
RPM is simply how fast your fan blades spin at a given speed setting.
Faster means more air...but only if the blades are pitched properly.
Also, some fans have a lower RPM at low speed and a higher RPM at high
speed, which means they give you more flexibility in the cooling
effect required. The best fans will give you 6 speeds from very low to
very high.
-
Height from Ceiling
In order for a fan to operate efficiently, there needs to be about 10
to 12 inches between the blades and the ceiling so that the air can
flow freely around the blades without bouncing up and down between the
blades and the ceiling. For this reason, you will find that ceiling
hugger fans (fans that mount flush to the ceiling) don't move very
much air. This type of fan will always have a small motor with
relatively flat blades so that it does not create enough turbulence to
cause it to wobble or shudder. You just won't find a
"Hi-Performance" hugger fan.
The blades on a typical hugger fan will be 7 or 8 inches from the
ceiling as opposed to 10 to 12" for a good quality performance
fan. The additional 2 or 3 inches makes all the difference in the
world...kind of like having a tire on a car that is just a little out
of balance. It may only take a small .5oz weight to balance the tire,
but without the weight, the tire will bounce up and down like crazy at
certain speeds. You should only use hugger fans if your ceilings are
lower than 8' high or there is some other restriction (such as a bunk
bed) that prevents you from installing a Hi-Performance fan that drops
down a few more inches.
For higher ceilings, a longer downrod is recommended in order to bring
the fan blades to about 8 or 9 feet from the floor so that you will
feel the air movement.
-
Motor - Size,
Power, and Quality
The motor is the most important component of a ceiling fan. The most
powerful motors will move the most air, providing the above factors
are present. High power fan motors are only available in the top of
the line models from each of the major name brands. You will find
these fans to be more expensive...but the difference in the amount of
air you will feel is quite remarkable and the performance, durability,
and efficiency is well worth the extra money.
Conclusion:
A well engineered ceiling fan takes all of the factors on this page
into account, and with precision testing, a "Sweet Spot" is
determined with the most efficient combination of blade pitch, shape and
size of the blades, RPM, height from the ceiling, and most importantly,
the capacity or capability of the motor. The
fans on our site that are rated 4 or 5, or are referred to as
"Hi-Performance" are fans that are well engineered to the
"Sweet Spot" and will give you the best performance for many
years. We are sure you will be satisfied if you purchase one of these
fans. We believe any other rating to be a compromise that manufacturers
make in order to design fans to meet lower price points.

Wow.. you gave me a complete imformation! thank you so much! i have some problem with my motor, and i want try to fix it myself..but how about voltage and frequency??my exhaust fan = 220-240- 50Hz, is that mean something?we need to compare that too??
Answer: We do not deal with exhaust fans. If you are trying to fix an exhaust fan, it is generally cheaper to replace the entire unit.
