leaf blower cfm vs mph

Do you watch Spongebob Squarepants? If you do, the leaf blower episodes are something you simply cannot help loving! Even if you don’t watch it, you might be familiar with a leaf blower, it’s pretty common to be honest.

Well, if you know about leaf blowers, there’s one thing that you might have always found confusing. Personally, I used to find it confusing until really lately too, and that’s exactly why I’m here to help you out with it. So, in today’s article, we’re going to take a look at this thing: Leaf blower cfm vs mph.

Cfm and Mph are two entirely different things. Now, both of them are supposed to show the efficiency of a model to a certain extent. However, which one is more important? And which one should be the one that you should check out first? Well, let’s find out in today’s article- let’s get started!

What is CFM?

Well, let’s begin by actually finding out what each of these two things really are. Once we have that figured out, we can surely find out the difference between the two with ease.

Let’s begin with CFM. It stands for Cubic Feet per Minute. What is actually refers to is the amount or volume of air that’s coming out of your leaf blower. Naturally, as you might have guessed, the higher the CFM, the higher the amount of air coming out of it.

However, one of the main things to keep in mind is that more volume does not always mean more speed. More volume can be achieved through different technologies, and even differently constructing the device. For example, properly angling the fans, and designing it in a way that it can easily draw air can make it really easy to achieve a higher level of CFM.

What is MPH?

MPH, on the other hand stands for Miles Per Hour. As you might have guessed, this is a much clearer indication of of the speed of the Air. The higher or lower your MPH is, the faster the air would be coming out of your leaf blower.

Now, inversely, it is also true that MPH does not show how much air is actually coming out. It might be really little, but it can be fast. So, that’s something that you might want to keep in mind too. Too little air isn’t going to be really helpful either, even if it is really fast.

To sum it up, MPH is an indicator of the speed at which air comes out of your leaf blower. It, however, does not indicate anything other than the speed- so you don’t know how much air is coming out or anything else about it.

Leaf Blower CFM VS MPH

So, well, the main question still stands, does it not? After all, which one of these two is more important to you? As we remarked earlier, CFM shows the amount of air coming out, and MPH shows the speed of it, but which one should be first for you to take a look at, and which one is more important of the two?

Well, this is one of those questions that aren’t too hard to answer if you look at it from a slightly different angle. While you need the air to be speedy, you need quite a bit of it for you leaves to fly. Again, while you do need a bit of air, you need it to be speedy at the same time. So, which one of the two is more important becomes a question harder to answer.

Quoting LawnSpecialist,

Cubic feet per minute or CFM is probably the first number you will want to look at. It measures the air volume velocity moved through the blower in one minute independent of its density. The engine of the leaf blower powers an impeller, or set of spinning blades in the housing that draws air in one end and forces it out through the tube. The volume of air that exits the tube of the specific model determines the CFM. The more air that moves through the machine the higher the volume, which translates into more leaves moved. However, the volume of air is meaningless if it is not moving fast enough, which is why MPH is also important.

So while you are shopping for a new leaf blower you are going to want to look at both air speed (MPH) and volume (CFM). The higher each of the numbers are the more work will get done in less amount of time. Now that we know what to look for in terms of power, we should take a look at which leaf blowers are going to be the most productive.

Which one is more important of the two?

Well, let’s get to the real question now. Honestly, the experts are a little divided in their opinion about it too, although almost all of them agree that both of them are really important things to consider.

So, to move it out of the way, you should actually pay attention to both of them. While one might be a little more important, it is undeniable that both of them are really important and you should pay attention to both of them when you’re considering the right model for your lawn.

But, which one should be the first one to go for?

Well, experts recommend checking out the CFM first. They believe that the amount of air plays a really major role when it comes to your leaf blower. Too little air, however fast it be, cannot really do much for your lawn. So, you need to know how much air is coming out before you actually look for the speed.

Quoting Opereviews,

Airspeed is important because it takes more of it to move heavier objects. Dry grass is one thing. pebbles, mulch, and wet leaves are another. Air volume is important because you need more to move debris in a larger area. But is blower MPH or CFM more important? Consider a couple of examples.

Take a straw and blow air through it at 300 MPH. You’ll make an impressive mess with your glass of milk or make a pretty effective blow dart gun, but you’ll accomplish very little in your yard. You’re in a low CFM situation, and the airspeed can only affect a small area.

On the other side of the coin, let’s say that you can produce 20,000 CFM but only get 15 MPH out of it. You get a nice breeze for a hot day. You and four of your closest friends can stay cool, but you’re only going to be moving the lightest sawdust. The low airspeed means you’re not moving much weight around.


We understand that this question might seem a little overwhelming at the beginning. After all, aren’t all technical terms a little hard to get used to?

But once you actually understand the concepts, it isn’t difficult at all. These two things are really different things, and you actually need to consider both of them. This is mostly owing to the fact that your leaf’s efficiency is decided by their combined figure. However, you might want to keep both of these figures reasonable instead one of being too low and the other being too high.
