CFM vs MPH are two leaf blower metrics that confuse many people, especially first-time buyers. These two metrics are essential for leaf blowers because they affect the device’s performance.Differences Between CFM and MPH

Their differences are confusing, but knowing the importance of each terminology will help you get the best leaf blower. Continue reading this article, and you will know their main differences.

Features  CFM MPH
Nozzle size It has a big nozzle to increase air coverage It has a thinner nozzle to increase air speed
Performance  The greater the CFM, the larger the area it can clean The higher the MFH, the greater the air pressure
Lowest recommended CFM of 200 MPH of 190
Best for Large areas or commercial spaces Small open areas with heavy objects

What Are the Differences Between CFM and MPH?

The main difference between CFM vs MPH is their meaning. CFM, or cubic feet per minute, computes the air volume from the blower every minute. MPH measures the speed of air that comes out of the blower, as it tells you how fast air is blowing from the nozzle.

Blowers have varying CFM and MPH, with different prices. Some combine great CFM with low MPH, and others have a great MPH with low CFM, confusing buyers. This leaves many people wondering; what is a good CFM and MPH for leaf blowers? When buying, choose blowers with over 190 MPH and 200 CFM.

If you want a specific number of MPH and CFM, consider the area you are working on and the type of debris. But always get a blower with a higher CFM. It will do the job faster and more efficiently.

Also, a greater CFM is a better blower choice because you can adjust its MPH by changing the nozzle. If the air moves slower, replace the large nozzle with a narrower one. Great CFM nozzles already have a great air force, so decreasing the nozzle diameter will make the air force even more significant, which can help you move heavier objects.

– Performance

Leaf blowers with varying CFM and MPH perform differently. Since CFM in a blower determines the size of an area the machine can clear in a minute, a blower with high CFM can be used for big yards. They produce more air that covers a prominent place, meaning they are the best for significant properties that are bigger and has more debris.

However, it also depends on the kind of debris you are moving with these blowers. While higher CFM leaf blowers produce more air to clean large areas, the air is not very strong. Therefore, high leaf blower CFM won’t efficiently move big logs or wet leaves effectively.

MPH is also important in backpack leaf blowers because it affects their performance. Since it measures air speed and density in a blower, a great MPH blower can clear heavy objects like bigger logs, wet leaves, and snow, and you will see that they can also blow leaves quickly.

However, strong MPH blowers are not the best for small areas. They have a thin nozzle, meaning the blown air covers a small space. You should also think about how the leaves are blown with too much force, putting them together in a pile will be problematic.

– Nozzle Size

Nozzle size affects CFM and MPH and how they would function and get the leaves out of te way as the leaf blower is functioning. When manufacturers want an electric leaf blower to remove leaves in a more extensive area within a minute, they install a big nozzle.

This lets out more air that pushes leaves from a larger space to one corner in a short time. Small nozzles will cover a small area, making the machine take longer to clean a smaller room within a minute.

Cordless leaf blowers with great MPH have a smaller nozzle to increase airspeed, and this means that it would get the job done in a different pace and a different efficiency. It blows the leaves forcefully away from you, meaning it can move heavier objects. You can also change the blower MPH by increasing the diameter of the nozzle. A bigger nozzle removes air at a lower speed.

– Functionality in Different Leaf Blowers

CFM and MPH are important differently in a blower. For example, some users will require a hand held leaf blower with a higher MPH and low CFM, one with a greater CFM power and low MPH, or one with both intense CFM and MPH.

A walk behind leaf blower with great MPH and low CFM will move many kinds of debris. It can be used to move sticks, snow, and heavier leaves effectively, but you will make a mess when removing dry leaves. Since the air comes out at high speed, the blower will push dry leaves farther from you, making it harder to collect the leaves together.

Also, a good CFM and low MPH blower will perform differently. The highest CFM leaf blowers cover an extensive area, making them suitable for a big yard.

But, since they have a low MPH, you won’t be able to move debris faster, and this way, you will have to leave behind heavy sticks. While you could compromise on the MPH depending on your yard size, the least MPH should be 190.

High CFM and MPH electric blowers are high-performance. The machines cover a large area within a minute, and since they blow air under high pressure, the debris moves faster. However, these gas-powered leaf blowers are mostly expensive.

So, what is better in a leaf blower, CFM or MPH? Both CFM and MPH are essential in a leaf blower, but it depends on the size of your yard and the type of debris you are clearing. Powerful CFM blowers will clean a large area faster, but low MPH can also affect the speed and type of garbage you move.

Exploring Leaf Blowers CFM, Its Importance, Pros and Cons

It takes a while for many people to understand the CFM leaf blower meaning, so you are not alone. CFM in a leaf blower measures the cubic meters the device covers in a minute. A leaf blower with great CFM is powerful because it removes dirt in an ample space within a minute.Best Features of CFM

So, what is a good CFM for a leaf blower? Your blower should have a CFM between 200 and 400. However, if you have a more oversized yard, get one with a greater CFM of 400 to 700.

– Choosing a Blower With Great CFM

While a blower with a great CFM is essential, you must combine this with other factors to get the best device. For example, the type of leaf blower also matters because some types can have the highest CFM, making them more potent than others as it has more power and functions more efficiently.

Cordless blowers mostly clean small areas, so you can get one with a CFM of 200-400. You can get more powerful cordless blowers if you have a larger yard, although their performance will be lower than push-behind blower types.

For instance, the push-behind types are more powerful because they could have a CFM of up to 3000. They are perfect for commercial areas like parking lots but are extremely noisy. Besides, because of their efficiency, these are more expensive.

On the other hand, the backpack blowers are also powerful, but different from the push-behind models. They are mainly used by users with large yards. Battery-powered options are also ideal because they have a long run time and high power, and this is the reason why they are expensive.

The corded electric blowers have a top-notch performance. These are affordable, and you will greatly appreciate them for their excellent work. The only downside is the code which limits the area of coverage when it comes to the CFM.

– Measures to Consider

All other factors considered, you need a leaf blower with a great CFM. Since CFM measures the quantity of air, an intense CFM blower can clean a large area quickly. The blowers have wider nozzles to push air to larger distances to collect leaves quickly.CFM Leaf Blowers

A battery powered leaf blower with low CFM will take a long time to collect leaves together. This machine has a narrow nozzle that covers a small area, but it has the power to moves the leaves at high speed. Therefore, low CFM blowers are not ideal for big spaces as the task would take such a long time to be accomplished.

A blower with a low CFM comes with a narrower nozzle. These machines cannot blow air in wider areas, meaning cleaning the space will take longer. While you can also compromise on the CFM with the MPH, stay within the recommended level of 200.

You should aim to ensure you also consider the type of CFM you are buying. Some varieties, like the push-behinds, are more powerful than electric corded types. What you purchase also depends on the kind of space you will use, which could be for commercial or home use.

Understanding MPH in Blowers and Its Importance

Miles per hour is the speed at which air is blown from the leaf blower. A high MPH means air leaves the blower at an incredible speed and blows leaves with a higher force. With greater force and speed, an air blower can blow leaves and other heavy objects like small stones and fallen twigs. An incredible MPH in blowers is essential to sweep dirt faster in small spaces.Understanding MPH in Blowers

These blowers mostly have a narrow nozzle to release air at a stronger force and faster speed. And if your machine’s MPH is too high, you can reduce it by changing the nozzle size. Installing a nozzle with a broader diameter reduces the airspeed, hence a lower MPH.

– Usage

The amount of MPH in the leaf blower you buy depends on what you want to use the device for. However, the minimum MPH should be 190. A leaf blower with less than 190 MPH will be too slow and inefficient, because it would be running at a weaker rate that you can imagine, so it won’t cover up more than that what you have in mind.

Blowers with higher MPH blow leaves with greater intensity because this is the significant measuring unit that they will be functioning with. However, while they do the work faster, you will have difficulties when putting the leaves together. This is because the blowers throw leaves at a farther distance than where you are.Usage of MPH Blowers

In short, you must also have in mind that the blowers with low MPH remove dry leaves at a very low pace because of the little force in the air. These mostly have wider nozzles and a great CFM.

While these will help you gather the leaves together, sweeping the pathway will take longer. Low MPH will also give you trouble when blowing large or wet leaves and other tiny objects because of the low air force, and when some that have a greater MPH, you will see how smooth and fast they will be at completing the task.


The difference between CFM and MPH is their definition. CFM is the amount of air from a blower’s nozzle, affecting the area the blower can clear at a particular time. The MPH is the speed at which air comes from the blower’s nozzle. This affects the force with which the air blows items and how quickly the blower can clean an area.

Choosing between CFM and MPH in a blower can be confusing, but your choice should be determined by what you want to do with the machine. An intense CFM is good if you clean large or commercial spaces, while a high MPH is excellent if you clean a small open area. When buying blowers, always go for one with a greater CFM, but don’t let the MPH be below 190.
