MPH And CFM For Leaf Blower

MPH And CFM For Leaf Blower

Have you been confused about what the CFM and MPH mean? What they stand for? What they have to do with a leaf blower? How they are different? Well, I have been too. But right here, right now in this article, we will be checking it out and we will be understanding both of them together.

Learning about the MPH and CFM has to be one of the most mistakable parts of the leaf blower. Even weeks after I learned about them, I still got confused and used them wrongly sometimes.

You might be wondering what’s the use anyway, you could just check the product details on the leaf blower box and that’s all. You do not even know if it is the right amount of CFM and MPH required to work on your yard.

Or you might be an interested fellow, who does not just want to buy a budget-friendly leaf blower but also wants to invest in the right one. The one that would provide you with enough power to perform the yard cleaning task well and on time. You are doing the right thing reading this and doing more research.

Well, this also means that you will be checking out a lot of specifications for the leaf blower of your choice. Specifications such as horsepower (HP/strength), Cubic Feet Per Minute (airflow), Miles Per Hour (speed), and weight. Sounds hectic, right? Yeah even for me too. But if you are patient enough, you will find the answers to your questions.

Understanding Leaf Blower MPH

Here we’ll be getting to know everything and anything we need to know about the MPH. Fortunately, I compiled a number of information I could lay my hands on for you.

What is MPH?

Mph fully means Miles Per Hour. It is the Standard Unit of speed that tells the number of miles an individual, vehicle, animal, or thing travel in an hour. It is most times written after a number. This symbol can be seen on traffic/ road indicators to show the maximum speed to be moved. It is used in Canadian, British, US, and Irish systems.

It is calculated by dividing the distance a mobile object moved by the time it used to complete its movement. For instance, using the case of a lawnmower that covered a yard of 250 miles in 5 hours.

The average speed, that is the miles covered per hour will be 50 mph. A leaf blower with a higher number of MPH means that it can move or blow leaves farther.

When Do You Need to Use MPH?

Miles Per Hour is used when referring to distance. How much an object can work, how long, and how fast the distance was covered. In the case of leaf blower, MPH is used to refer to how far it can blow fallen leaves in your yard, unlike the CFM which refers to the amount of air delivered. So other should be used when referring to distance. A high MPH allows you to blow leaves from the top of your car but not in a large pile.

Other Things You Should Know

The MPH of your leaf blower is useful for determining how quickly and violently it can sweep leaves and other debris away from you. The faster and more powerfully that material can be pushed away, the higher the MPH rating. In general, the larger and more powerful the motor or engine of a leaf blower, the higher the CFM and MPH ratings of the blower.

The impeller, which is the fan-like portion inside the blower that provides the airflow, also has an impact on these ratings. CFM and MPH are both dependent on the impeller blades of a leaf blower angle of rotation, speed, and length.

The higher the impeller’s degree angle, the more air is created and the harder it is to maintain the leaf blower speed.

Understanding Leaf Blower CFM

Although the CFM has been mentioned earlier, you do not know what it is about. Here, from here, we’ll be seeing all about it.

What is CFM?

CFM fully means Cubic Feet Per Minute. It is the measurement of airflow. It is found by calculating how many cubic feet of air pass by a motionless point in a minute. In the case of the leaf blower, it is the quantity of air delivered by a leaf blower through its nuzzle in a minute.

For instance, a leaf blower that delivers 600 CFM means that it blows 600 cubic feet of gentle wind (air) every minute. The higher the amount of CFM, the more air it delivers and the more capable it is to move things.

Let’s say a leaf blower of 500 CFM will be able to move a couple of sticks around. A leaf blower of up to and more than 800 Cubic Feet Per Minute might be able to move little stones and pebbles.

When Do You Need to Use CFM?

Cubic Feet Per minute deals with how much air a leaf blower delivers per minute. This amount of air does not guarantee that air will go too. A high CFM allows you to blow plenty leaf but not so far.

Other Things You Should Know

As a homeowner, you should know the best CFM. The best CFM is in the middle range, between 350 and 600 CFM, with a wind speed north of 190 MPH. Too low and you won’t get the job done; too high and you’ll lose control of the leaves, which will make the work take longer.

Furthermore, I just thought you should know about the Newton force. When comparing blowers, the number to check for is the Newton force. Because of how it’s measured, it takes into account both MPH and CFM to offer you a single number that represents the total amount of force a blower produces.

In a test conducted by Kenny Koehler, cordless blowers produced between 8 and 17 N (Newtons), while Pro backpack blowers produced between 28 and 39 N. It’s much easy to discern which blower is more powerful using a simple “larger is better” assessment.

This was used to confirm that both the MPH and CFM are needed for the leaf blower to perform well. And that there could be a balance or in the least a way to ascertain if the leaf blower can perform so much work.

MPH Vs CFM For Leaf Blower

Yeah, I was confused about both terms too. Like, aren’t they moving stuff and blowing air? Yes, they are but they are not the same. While CFM deals more with power than speed, MPH does the latter than the former.

Cubic feet per minute (CFM) is the standard for measuring the volume of air pushed through the unit and from the nozzle.

The speed at which it is pushed is measured in miles per hour (MPH). The first is similar to being struck by an air compressor hose, while the second is similar to poking your head out a car window. The difference can alter the way your leaf blower performs.

Below are the type of leaf blowers with how much CFM and MPH they can deliver:

  • The electric leaf blower, they are fueled by an incredibly long extension wire and produces a lot of power, but the cord can be a pain to manage. Most versions have a CFM output of 350 to 450, which equates to roughly 190 MPH or higher. They are, however, the lightest, lowest-maintenance, and most affordable, as well as the only ones that never need to be charged or re-fueled.
  • Because the battery-powered leaf blower runs on rechargeable 18-volt batteries, they are a more versatile option for domestic applications. The CFM can be extremely high, while the MPH is minimal. A 500 CFM model could only produce 160 MPH off the air force. Depending on the size, the battery will last at most one hour. Again, excellent for household use, but not for professional landscaping unless you have a lot of batteries and patience.
  • Gas-powered leaf blowers are the best option for commercial efficiency. They are by far the costliest of the alternatives. Because of the gas engine and fuel storage, they are heavier, however, most of them come with a backpack mount to aid with the weight. They are quite adaptable and can last for long with just one charge. Because gas-powered systems utilize engines rather than motors, the larger the engine, the more CFM. The Echo 58.2cc model, for example, will blow at 217 MPH and produce 517 CFMs.

A high MPH rating on a leaf blower does not automatically guarantee that it has higher power. If the CFM requirements are high, even a low MPH leaf blower will be quite powerful and powerful. In general, go for a higher CFM, not a faster MPH, if you want to move more leaves.

A bigger, weightier motor with more strength (HP) will often produce a higher CFM rating. You’ll be carrying a bigger leaf blower on your back, but you’ll be able to move your leaves in half the time. Some folks prefer speed over comfort.

What’s Best for My Yard?

Picking the right leaf blower for your yard depends on a lot of factors. It is these factors that point you towards the best. It also helps to narrow down the choice of leaf blower you could go for.

These factors include:

  • How large your yard is
  • How much load you can carry
  • How much you are willing to spend
  • How many trees are in your yard
  • The attribute you want in a leaf blower
  • And why do you need that type of leaf blower

The general rule is to buy as much CFM as you can within your budget. However, it does not stop there. Sure, It might be able to bring you the highest power your budget cuts but not the best choice if the unit is too heavy or lacks some of the spec you need. 

Cleaning up your driveway or patio is simple enough for most households using a low-cost, low-power electric leaf blower. A 200 or 400 CFM leaf blower is quite okay for just cleaning smallee amounts of leaves, if that’s all you really need to do. 

However, if you own at least an acre, you may want between 400 and 700 CFM, depending on the number of trees you have and how rapidly you want to clear that acre. Although It will probably produce so much noise and be too big for your grip, it will produce enough power to move wet and dry leaves even little sticks or sand.

Homeowners are most likely to enjoy leaf blowers that delivers up to 1000 CFM especially if they have up and more than 2 acres of land, many trees, a business, or sometimes volunteer to clear the lawns of neighbours, friends or family members. Units as large as that covers large jobs easily and faster. It’s not just about power, though. It’s also crucial to use proper leaf blowing techniques.


I hope that through this article, the difference between the Cubic Feet Per Minute and Miles Per Hour is understood by you. Their importance and also how they are used. Both the CFM and the MPH are needed for the leaf blower to perform perfectly. So why see so much advantage in one, do not discard the other one.

When purchasing a new leaf blower, do well to consider the factors so that you do not lose the focus you have on the right one to the wrong one. Considering the factors keep your mind steady on what you want.

The factors include how much you can spend on the leaf blower, how big your yard is, how many trees are in your yard, and some more. Being penny wise does not stop you from picking the right leaf blower for you, because there are a lot of affordable ones that perform so well.
