In this article, we give you some insights into the meaning of CFM (Cubic Feet Per Minute), which is one of the most important factors when buying a fan. We also describe how you can use it to calculate the amount of electricity your fans will consume.
The CFM of your fan is a measure of the airflow rate in cubic feet per minute. This is an important factor when buying a fan because it affects how loud the fan can be.

What Does CFM Mean?
CFM stands for cubic feet per minute. Also referred to as airflow, the CFM is how much air a fan moves. When the ceiling fan is at its highest speed, the measurement is taken using both the volume of air and the rate at which it moves. The number depends on a few things. The fan’s motor, the blade pitch, and the length and/or shape of the fan blades. Ultimately that means the greater the CFM, the more air a fan moves.

In the United States, we can use the CFM rating system that was introduced by the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) in 2007. In this system, the CFM is a measurement of air volume flow per minute and is given as a unit of cubic feet per minute (CFM). The CFM rating system is divided into two different classes: Class A – This is the lowest rating and is used for ceiling fans with a capacity of less than 4,000 CFM. These fans are generally smaller in size and usually have a very low speed.
CFM & Measuring Airflow Efficiency
CFM is key when determining a fan’s airflow efficiency. Airflow efficiency is the CFM divided by the watts/amount of energy used to run the fan at its highest speed. A CFM of 75 is the minimum number to make a fan efficient.

You could have a fan that moves a lot of air (with a high CFM), but does so at a high wattage, making the fan inefficient. Look for fans that operate at a high CFM and low wattage to increase the efficiency of the power usage in your home. Also, consider a ceiling fan with a light powered by an integrated LED kit for further efficiency.
How to Determine CFM & Efficiency Metrics
Instead of handling calculations yourself, we make that part easy for you. You’ll find the airflow, power usage and airflow efficiency metrics listed in the product details for each of our ceiling fans.
Do High CFM Fans Are Good?
It is really a matter of opinion, but yes it’s very possible that high CFM fans are better. The reason why high CFM fans are better than low CFM fans is because the air movement through a larger area of the radiator is much better than through a smaller area. Higher CFM fans move more air, and are therefore better at cooling your home.
What Is A High CFM Ceiling Fan?
It’s great for large rooms if the ceiling fans are high because they are able to move a lot of air. The ceiling fans have been designed to move more air than normal ceiling fans. The ceiling fans with the highest capacity are in the range of 4,000-CFM to 10,000-CFM.
They tend to be designed differently to push more air because they have a bigger span.
What Does CFM Mean For Ceiling Fans?
The CFM rating, which stands for cubic feet per minute (CFM), is a measure of how fast the fan blades rotate. The higher the CFM rating, the faster the fan spins. This in turn means that the fan will move more air and circulate it throughout a room or other space. Ceiling fans are great for rooms with high ceilings because they can circulate air and bring in cool air from outside while keeping warm air from escaping.
However, there are many different types of ceiling fans available on the market today, and each one has its own CFM rating. The CFM rating is determined by the size and number of the blades on the fan. The larger the fan, the higher the CFM rating.

The CFM rating can also vary based on the number of blades in the fan. A single-speed fan, for example, may have a lower CFM rating than a three-speed fan, even though the single-speed fan will operate at a slower speed. CFM ratings are usually printed on the label on the back of the fan. Many fans also have the CFM rating listed on the packaging or in the instruction manual.
What is the Best CFM Rating for a Ceiling Fan?
As general a good CFM ranges from 4,000 to 5,000 for normal size rooms and for better ranges from 5,000 to 6,000 which is quite good and for the best is over 6,000 which you may find generally in industrial or large spaces.
