What to Look for in a Range Hood? [All About Range Hoods]

Range hoods act as a complete lifesaver all the time. Not only do these devices work at eliminating smokes and fumes, but they also ensure recirculation of air inside the kitchen.

And, with the flourish of modern technology, the demand for these mechanical devices has increased as well. Especially in the commercial kitchen, almost every chef wants a range hood now.

As the demand for these devices has increased, the availability has increased too. Hence, there are almost a thousand of these devices lying around. But, knowing what to look for in a range hood can allow you to know what to expect.

Still feeling lost? Well, fret not, we’re here to make things easy. Below, in the article, we’ve answered all of your confusions. So, let’s begin –

What Is Range Hood Ventilation?

Before trying to even know what to consider inside a range hood, it’s better to know about the definition. Well, we won’t budge you with a bookish definition of any sort.

So, to be precise, a range hood is basically a device. Here, the device ensures that all types of grease and combustion products are evacuated from the kitchen. And this device takes out all kinds of smoke and grease in the form of air.

Hence, ventilation of the range hoods is extremely important. Generally, it’s a type of mechanical fan that’ll remove all sorts of steam in the kitchen.

By ventilating the range hood, you’ll ensure that no smoke or grease accumulates in your kitchen by any means. Plus, it’ll even enhance the overall environment.

What to Look for in a Range Hood?

Now that you know the correct definition of a range hood, it’s time to know what kind of factors are essential. Normally, range hoods are quite available due to their demand in the market.

However, if you don’t know what to look for, the confusion can take place in a matter of seconds. But don’t you worry, as we have it all figured out. So, let’s just get right into the factors –

i. Maintenance

Before even buying the range hood, it’s important to consider whether you’re up for maintenance. Here, it’s not only about the efforts, but the cost will also matter as well.

So, it’s very crucial to select the hoods that are easy to manage and clean at the same time. However, there’s another thing to consider when talking about maintenance.

Yes, you guessed it right, we’re talking about the parts. You see, if the spare parts aren’t easily available, then the replacement procedure will be a pain. So, you’ll need to consider these factors. Otherwise, you will suffer a lot with the machine in the long run.


ii. Budget Factor

Budget matters! If you don’t have the right budget, then you’ll face a tremendous amount of confusion with the buying process. So, it’s important to set a budget before even selecting other factors.

By selecting a budget, you can quickly identify what features you’ll get and what attributes you’ll have to compromise.

Budget Factor

iii. Noise Factor

Oftentimes, the range hood creates a lot of noise. This can eventually make the neighbors and the elderly complain about the hoods.

In the end, you won’t be satisfied with the performance of the hood due to the loud noise. So, select hoods that draw in the air towards the perimeter instead of larger areas. By doing this, they’ll reduce the noise to some extent.

Noise Factor

iv. Fan Power/Number of Fans

Fan speeds determine how much efficiency the hoods will carry with them. Here, the hoods need to be strong enough to prevent strong odors. But if your hoods have two different fan settings, then you’ll be good to go.

v. Kitchen Layout

The kitchen layout will play a part in choosing the hoods. But why is that? Well, if you don’t have the right layout, then you won’t be able to set the hood in the right manner. Plus, the proper design will set everything accordingly.

According to the experts, it’s better you mount the hood 24-30 inches on the top of the cooktop.

Kitchen Layout

vi. Airflow

The better the airflow is on your range hood, the better it’ll ventilate the combustible products. However, there’s no guarantee that it’ll remove steam quickly when you have better airflow.

That said, you won’t surely have problems by ensuring a better airflow through your hoods.

Different Types of Range Hoods

By now, you’ll have a clear idea about what factors you’ll need to consider when looking at range hoods. However, these considerations can differ from a single type to the other.

So, it’s better to know which types these hoods come from. For that, we’ve prepared their types in detail below. Let’s just check them out –

1. Ductless Hoods

Firstly, let’s take a look at the ductless hoods for a minute. Here, the options are located under the cabinets or under the walls. These types of hoods help at preventing smoke and heat buildup in the kitchen.

Other than that, they help with directing the steam and heat away from the stovetop. In accordance with this, the filters trap in all types of grease and oil buildup. You can even reduce odors inside the kitchen due to the carbon filters present in the hoods.

2. Wall-Chimney Hoods

Usually, wall-chimney hoods are located on the spots where there will be no cabinets situated. It also works at the mounts exposed on walls and to outside vents.

3. Downdraft Hood

These types of hoods work in reversing the direction of fumes and smokes. Here, they reverse the direction into the exhaust. As a result, the fumes are directed towards the ducts situated below the floors.

Hence, they won’t allow fumes and smoke buildup in the kitchen. Even though they don’t have the reputation of being used on every kitchen part, you can use them on the islands.

4. Under Cabinet Hoods


Similar to the ductless hoods, you can mount these hoods under the cabinet wall as well. They can even work inside walls, ceilings, and soffits vents.

Besides, these models help at directing the smoke and steam towards the suction end. As a result, it doesn’t also allow steam buildup on the face of the cabinet. And it brings those steam down to the range hood’s suction end.

However, the only caveat you’ll face with these hoods is that the design kills a bit of space in the kitchen. So, you won’t get to save a lot when it comes to storage issues.

It’s better to avoid these types of hoods if you don’t have a large enough kitchen in the first place. So, you’ll definitely need to give it a thought.

5. Island Hoods

When it comes to mounting issues, these hoods can be vented through the ductwork. Normally, these ductworks are located on top of the ceiling. And they even lack cabinets or walls alongside them.

Here, you’ll need cabinets and walls to funnel in the fumes. If you don’t have this support, then your steams won’t be removed completely.

6. Ducted or Vented Range Hoods

You’ll find all kinds of range hoods around. However, when it comes to ducted or vented range hoods, you’ll get a lot of options lying around. So, are they worth it? And should you spend your time considering them for your kitchen?

Let’s take a look at them and find it out ourselves.

Ducted range hoods work at eliminating all sorts of smoke and fumes from the kitchen. But these hoods are connected to a duct. Here, the ducts or vents are connected using a pipe.

And the pipe works at channeling the airborne particles to the outdoors from the kitchen. Normally, you’ll find these types of hoods in commercial types of kitchens.

This is because these hoods are capable of transporting huge amounts of fumes and smoke outdoors. Plus, they even project lesser noise when compared to other types of hoods.

Ducted or Vented Range Hoods

7. Ductless or Ventless Range Hoods

When it comes to the ductless options in the market, you won’t get them using a pipe to transfer the fumes. Here, they work at transferring the fumes with the help of an exhaust system.

In fact, they even work at transferring the dirty fumes and smoke outside. But it doesn’t end there. Here, the powerful exhaust fans work at circulating the air inside the kitchen.

As a result, these hoods actually try to improve the quality of the air. So, they cancel out the fumes and smoke and replace it with better air. And how does it do that?

Well, due to the presence of various filters, it circulates better quality air inside the kitchen.

Ductless or Ventless Range Hoods

Ducted vs Non-Ducted Range Hood

Well, you’ve seen the definition of both these types of hoods. However, there are differences between them. To make things clear, we’ve provided a head-to-head comparison between the two. So, let’s just check them out –

Ducted vs Non-Ducted Range Hood


  • Ducted Range Hoods

These hoods work well at eliminating all sorts of grease, fumes, and smoke from the kitchen. Here, the hoods use a pipe when looking at the elimination process. And the pipes effectively work at transferring the particles from the kitchen.

Also, they don’t cause much noise in the kitchen and work at increasing efficiency at all times. When it comes to removing steam, these hoods transfer vast quantities of steam at the same time. So, you’ll find them in most commercial kitchens.

  • Non-Ducted Range Hoods

When compared against the ducted hoods, the ductless hoods function quite differently. They don’t work using a pipe. However, they do have exhaust systems located in them.

And the best part about this system is that they work at circulating air inside the kitchen. As a result, the fumes are eliminated, and better-quality air enters the kitchen. The hoods perform this function due to the presence of various filters.

When it comes to mounting, the ductless hoods take the upper hand as they can be mounted anywhere. So, you can mount them without a problem. But you’ll need to replace the filters once in a while as they’ll need to function well.

Our Winner : 

If you want our suggestions, then we crown the ductless range hoods as the winner. This is because these hoods just provide a lot when it comes to benefits. And you can even mount them almost anywhere.

How to Measure Range Hood Strength?

It’s important to know about the strength of the range hood. Otherwise, you’ll be bombarded due to the electricity bills. Plus, it won’t even allow you to save up on costs as well.

So, how can you measure strength?

Well, firstly, take a look at the CFM of the fans. Here, the cubic feet per minute will indicate the power of the hood. Normally, you’ll need around 1 CFM for 100 BTU’s.

However, things aren’t as easy as it sounds –

This is because the airflow depends heavily on the exterior ducts. Here, by decreasing the ducts on the exterior, you can decrease the possible airflow as well. So, CFM won’t always demonstrate the correct amount of airflow in the hoods.

How to Measure Range Hood Strength

HVI has developed a pretty accurate way of testing range hoods. This method includes drawing a curve that depicts the CFM on one axis and the static pressure on the other.

According to them, the standard rating should be 0.1 on the said static pressure axis. That is if the standard is met, the hood can practically be labeled as well-designed.

i. Filters for Range Hoods

We’ve spoken about the filters of the range hoods in the earlier sections. These filters are made of charcoal or metal. And, yes, this filter helps at removing all types of dirt and grease.

It doesn’t end there; it’ll even help at providing proper ventilation in the kitchen. And the best part about these filters is that they help recirculate healthy air inside the kitchen.

What it’ll do is cancel out the toxic air pollutants, and filter them to bring out healthy air in your cooking area.

If you want to know the filter types for these hoods, then let me explain. Among the types, we’d recommend the charcoal, mesh, and baffle filters.

ii. Fan for Range Hood

As we move further towards the middle of this informative guide, let’s talk a bit about the fans of these hoods. Starting off, the fans are normally located on the vented hoods.

Here, the fans are attached to the duct. So, when it moves, it’ll bring out toxic pollutants from the kitchen to the outdoors.

And it doesn’t end there; the fans actually take the extra effort, and clean the air and recirculate them in the cooking space.

Other than that, the exhaust fans in the hoods work at circulating air out of your kitchen. And the fans make it easier to take out smoke and fumes away from the area.

Another bonus point of having exhaust fans in the hoods is that they won’t allow smoke buildup in the kitchen whatsoever.

iii. Range Hood Sound Levels

Before we even break down the sound levels in the range hoods, let’s discuss why it is even important to discuss them. Well, if you select a quieter hood in your kitchen, then it’ll ensure that everyone is working peacefully.

At the same time, no one will actually appreciate it if your hoods are creating a loud noise all the time. At that moment, it’ll even nullify whatever sort of benefits you’re getting out of them.

Hence, it’s equally important to know the sound levels when considering a hood for yourself. Generally, sound levels are dependent on the power of the range hoods.

As a result, the more the CFM of a hood will be, the more sound you’ll get from it. Apart from that number, hoods produce from 3-7 sones (dependent on the power).

If you didn’t know about sone, then it’s the basic unit of loudness. So, the sound of the hood ranges from 3 to 7 sones depending on the CFM.

On the other hand, the sound of the hoods can increase when you’re cooking something heavy. The hood puts extra pressure on the efficiency. Hence, you’ll get an added level of sound from it. Other than that, the sound will be low when you’re working on light-set activities on the hood.

What Size Range Hood Do I Need?

Now that you know what kind of hood you’ll need in your kitchen, another important consideration has to be done right here. And that’s the overall size of the hood. It is one of the important factors which you need to consider, to get the ideal range hood for yourself.

Even though the kitchen layout does play a key role in selecting the hood size, you’ll need to determine the size range as well. Generally, you’ll get range hoods from the size of 30-36” in width. But they aren’t powerful enough and have a CFM of only 100-400.

Here, a general rule of thumb would be to purchase a hood 6 inches wider than your range. As a result, you’ll have three inches to spare on both sides. For example – if you’re going for a 24″ range, then a 30″ hood would be just fine. Similarly, you can calculate for other ranges as well.

What Size Range Hood Do I Need

Should Range Hood Be Wider Than Cooktop?

Range hoods don’t have to be wider than the cooktops. However, they’ll need to have at least the same width as the cooktops. And you can even increase their lengths and keep them 3” longer on the sides.

When looking at the widths of the hoods, the most common ones are from 30-36″. But if you’re going for optimal performance, then installing hoods of 20-24″ will be just fine.

Here, the 24” hood will be okay for the gas cooktop of 24-30”. So, in the end, you’ll need to select the hoods as wide as the cooktops.

Should Range Hood Be Wider Than Cooktop

How Many CFM Do I Need for My Range Hood?

Before knowing how much CFM you’ll need for the hood, it’s better to know what a CFM is! Well, if you didn’t know about the definition, let me break it down –

A CFM is basically cubic feet per minute. It’s the measurement of the airflow. And it even describes the ventilation and the heating capabilities.

But you may ask- why is it needed to know about the right amount of CFM. Well, you’ll need to know that because having too much can increase the electricity bills.

That said, how many do you actually need?

To be precise, you’ll need around 100 CFM in your range hoods to make it work better. Here, for a 12-inch width of the stove, it’s better to settle down on 100 CFM.

Thus, the amount of cubic feet per minute or CFM will vary according to the size of your stove. So, let’s do a quick math. If you have a 30″ stove, go for a range hood of 250 CFM.

How Many CFM Do I Need for My Range Hood

Distance Between Stove and Hood?

Clearly, it’s better to have a fair distance between stoves and hoods. Here, the hood must have a distance of almost 65 centimeters. And why is that?

Well, if the hoods are too close to the stove, then they can catch fire anytime. Plus, they even run the risk of getting any sort of heat damage as well. So, not having a proper space between stove and hood can invite many unwanted problems like these.

Distance Between Stove and Hood

When it comes to maintaining a distance so that the hood doesn’t catch fire, the same goes for not keeping them too far away. This is because if the hood is too far away, they won’t be able to suck the fumes.

As a result, you’ll need to work on a limited range when putting the hoods over the stoves. We recommend going for a maximum distance of 80 centimeters and a minimum distance of 65 centimeters.

What Does Convertible Range Hood Mean?

Convertible range hoods are basically the type of hoods that convert from a ducted hood into a ductless functionality. Typically, they’re like ducted hoods. But you can convert them towards being ductless.

Here, to convert them to a ductless vent, you’ll need to use a recirculating kit. And the kit works at venting the air from the kitchen to the hood. Also, the charcoal filters work at making the air healthy and putting them back into the kitchen.

By converting a ducted hood into a ductless hood, you can easily save up some expenses. Plus, you’ll even ensure that you can eliminate all kinds of fumes and smokes from your kitchen.
