Worried about rust and moisture in your space? Are you looking for the best through the wall exhaust fan? The exhaust fan is a device that pulls air out of a room using an engine that turns its edges. In order to keep your kitchen ventilated, you need these appliances.

Those who consume food or heat water may feel a bad atmosphere for relaxing when there is dampness in the air, steam is produced, or steam is created by cooking. Air exhaust fans in kitchens allow outdoor air to fill the room and create an ideal environment inside by removing hot and muggy air.

An exhaust fan is controlled with a divider switch and is powered by the power. A temperature regulator, however, is found in some new models that activates the fan automatically when the temperature reaches a certain level.

Through this buying guide, you will be able to find out which is the best through the wall exhaust fan on the market for your needs, and their in-depth reviews will help you make an informed decision. Now let’s get to reading.

What is an Exhaust Fan?

Air is drawn out of the space by an exhaust fan powered by an electric motor that turns blades. Your kitchen ventilation would not be complete without them. Wall switches are used to control exhaust fans, which are powered by electricity. However, some new models include thermostats that automatically activate the fan when a predetermined temperature is reached.

In addition to the smells produced by cooking activities like spices, oil burning, etc., cooking can produce an odor that can spread throughout your home if not pushed out. Kitchen exhaust fans keep the air fresh by pushing the bad air out of the kitchen and maintaining a better airflow.

1. Broan-NuTone 9093WH Exhaust Fan, Heater, and Light Combo, Bathroom Ceiling Heater, 1500-Watts, 70 CFM, White


  • Power Source: AC
  • Brand: Broan-NuTone
  • Color: White Painted Enamel
  • Heating Method: Forced Air

Bathroom exhaust fans benefit from the addition of a heater. A Broan NuTone 9093WH bathroom ceiling fan with a heater is the best option among selected ceiling fans with heaters. In addition to heating up the air to more than 5,000 BTU, the fan includes a 1,500W heater.

A Broan NuTone 9093WH bathroom exhaust fan operates at 70 CFM. This airflow is ideal for bathrooms with 65 square feet; that’s a 8 by 8 room. It can also be installed in smaller bathrooms.

You can provide your bathroom with additional heating by using the heating element. You’ll especially appreciate that as soon as you step out of the shower. An extra layer of ceiling heat typically reduces the chilling sensation after a shower.

Dual lights are also included in Broan NuTone 9093WH along with the heater. Incandescent light of 100W provides the primary illumination in the bathroom. With the 7W nightlight, you have the option of dimming the light (perfect for bathing).

A fan that generates heat in the bathroom has the disadvantage of generating more noise. There is usually more noise from the heating element than from a fan alone. So Broan NuTone 9093WH makes 3.5 sones of noise, about 50 decibels. Compared to other space heaters of 1,500W, these levels of noise are not excessive.

You’d be wise to consider the Broan NuTone 9093WH if you need a bathroom exhaust fan that includes both light and heater:


  • Suitable for rooms up to 65 square feet, this exhaust fan includes a heater and light. The housing measures 13-1/4 by 13-1/4 by 7-1/2 inches
  • Easy-to-use switch controls all functions right out of the box due to the included four-function wall switch
  • Including all pieces needed for easy installation and/or replacement for DIY’ers
  • At 3.5, it has optimum performance with a 1500W heating element and 70CFM ventilation fan, sufficient for a few minutes of warmth while keeping the whole house quiet.
  • The bright 100-watt incandescent lighting creates a pleasant environment with even illumination, allowing you to focus on the details. When you visit the bath at night, this 7-Watt nightlight will provide a soft glow that will light up the room. It doesn’t matter how many times you change the paint color, the white enamel grille is an excellent match for any decor!
  • The heating element produces 5,000 BTU of heat with a power of 1,500W
  • A 70 CFM airflow is best suited to bathrooms that are 65 square feet (8 x 8 bathrooms, for instance).
  • In the bathroom, you can use only this powerful 100W light
  • Take a bath with this dimmable 7W nightlight
  • Removes the chill after showering
  • The heating element contributes to higher noise levels than average (3.5 sones)
  • The cost of running a 1,500W heating element is approximately $0.20 per hour

8. Broan-NuTone L300 High Capacity Ventilator Fan, Commercial Exhaust Fan, 2.9 Sones, 120V, 308 CFM, White


  • Brand: Broan-NuTone
  • Electric fan design: Exhaust Fan
  • Color: White
  • Style: 308 CFM
  • Power Source: AC
  • Room Type: Kitchen, Bathroom
  • Controller Type: Button Control
  • Mounting Type: Ceiling

If you have a big bathroom, you won’t be able to breathe with a 50 or 100 CFM fan. A bathroom with 150 square feet or more will require a high CFM bathroom fan. There is no doubt that the Broan NuTone L300 is the strongest bathroom exhaust fan on the market.

The NuTone L300 from Broan is a powerhouse. The Broan NuTone L300 can produce 308 CFM of airflow, which is much more powerful than most bathroom fans which generate less than 150 CFM. There is a 100% increase in airflow over standard fans.

For bathrooms up to 290 square feet, this powerful exhaust fan is ideal. With 308 CFM airflow, the 290-square-foot bathroom’s air is changed 8 times per hour (8 ACH or every 7.5 minutes).

It is important to consider the noise level when installing powerful high CFM bathroom fans. If the noise level exceeds three sones, you may have an issue with the fan. As a result, the Broan NuTone L300 emits less than 48 dB of noise at most (2.9 sones). With both power and quietness, this exhaust fan meets all of your exhaust fan needs.

There is no light in Broan NuTone L300, which is a drawback. There are usually set-up lighting systems in large bathrooms (because they need high-flow exhaust fans) to adequately illuminate the entire area. That setup could be hampered by additional light.

It is surprising that Broan NuTone L300 costs less than $200 despite being so powerful. As the strongest high-power bathroom exhaust fan on the market, it delivers 308 CFM of airflow and covers up to 290 square feet of bathroom space.

Unique fan blades and a built-in damper enhance the fan’s performance, minimizing backdrafts and maximizing its efficiency.

It will be impossible for you to smell bad smells in your kitchen due to all these features. You might want to grab a Lasko fan when you’re cooking because it can get extremely hot in a kitchen.

In addition to being easy to install, the kitchen wall exhaust fan is highly efficient. Putting a hole in the wall to place the fan is the most difficult part of the installation. It differs from the Single mounted by TPI Corporation. The twist-lock installation of the fan makes everything else effortless.

 The pieces are simply placed where they need to go and twisted into place to lock them. While this Broan-NuTone wall-mounted fan is generally durable, some parts of the housing are flimsy, especially during installation. When putting everything in place, we recommend taking care.

How To Choose the Best Through the Wall Exhaust Fan?

You should consider the following factors when choosing a ventilation fan for your kitchen.

1. Mounting Type 

A ceiling fan, a wall fan, or an exhaust fan mounted on the outside can be mounted. Exhaust fans mounted on the wall are the best choice for kitchen fans. It is also possible to mount the unit outside, as the noise is generated from the outside. Nowadays, ceiling fans are the most popular exhaust fans for modern kitchens, since they provide better ventilation within the ceiling.

2. Noise Level 

Noise is measured in sones, which is the volume of sound produced by most exhaust fans. It is considered quiet when the exhaust fan generates two or fewer sones, while it is very noisy when it generates four or more sones. Sone value determines how much the exhaust fan will cost. Exhaust fans that are small and lightweight are less likely to produce noise than those that are heavy and large.

3. Special Controls  

Motion-sensing exhaust fans, which automatically shut off the fan when you leave the kitchen, are among the special and pleasing features of these exhaust fans. Humidity sensors activate the fan upon detection of moisture, another important feature. Several exhaust fans come equipped with low-wattage night lights for nighttime navigation.

4. Airflow Capability 

All exhaust fans measure airflow in cubic feet per minute (CFM), which is the amount of air moving per minute. Small exhaust fans have an airflow of 30-50, while larger models have an airflow of 200 to 300.

You can determine the best CFM rating for your kitchen by multiplying the square footage of your kitchen by the height and dividing by 7.5. Using this formula, you would need 50 CFM for a 50-square-foot kitchen.

5. Duct Size 

An exhaust fan’s performance is also dependent on the duct size, which is important for efficient operation. A suitable duct conductor should be installed on the fan, and it must be routed in the correct direction. The length and composition of ducts determine the force and pressure that ventilation fans put in them. To ensure the exhaust fan works effectively, ensure the duct diameter is adequate.

6. Capacity 

The proper ventilation of a kitchen depends on an appropriate amount of airflow. CFM stands for cubic feet per minute, which is the measurement of the airflow in a kitchen exhaust fan. CFM airflows of small exhaust fans range from 30 to 50, while those of larger models range from 200 to 300. Make sure your kitchen is well-ventilated by choosing an exhaust fan based on its size.

7. CFM

Cubic feet per minute is referred to as CFM. In an exhaust fan, it is used to measure the amount of air pressure being pushed out. An exhaust fan’s performance and delivery are determined by its CFM.

A model with a higher CFM is recommended if you plan to serve a larger room or to supply more air to your kitchen. Our recommendation would be a moderate CFM if you have a small kitchen because you won’t need quite as much air to cool it.

CFM isn’t everything, so keep that in mind as well. Airflow claims from exhaust fan makers could simply mean faster venting, and might not necessarily mean that fumes and odors are absorbed and removed better.

What is our recommendation? Make the right selection for your exhaust fan without putting too much emphasis on CFM.

8. Blade Material

To ensure the durability of the exhaust fan unit, ensure that the entire unit is constructed of high-quality materials. It’s important to ensure that your exhaust fan is made from rustproof material if it’ll be exposed to a lot of moisture.

9. Ease of Use and Installation

You will need to make sure that the installation of your range hood or kitchen exhaust is both quick and easy if you intend to do it yourself. If you plan to install the exhaust fan, make sure you follow the manufacturer’s directions and ensure that there is an adequate room above the burners and elements.

Make the most of the ducting by using the biggest walled-metal ducting and venting outside whenever possible. The duct runs should be kept as short as possible and bends should be minimized. You can prevent backdrafts by installing a cap on your roof or wall exterior. If you cook more frequently, have them cleaned every month, but if you wash them every three months.

Benefits of Exhaust Fan

There are a number of benefits to exhaust fans, including the following:

  • You can damage your ceilings and walls if excessive moisture and oil buildup is not removed by exhaust fans.
  • Air quality is improved by these fans, as unpleasant odors are drawn out of the room, ensuring a clean environment.
  • In a kitchen area that becomes hot due to cooking activities, it quickly vents out the hot air and cools it down.
  • Your kitchen’s visibility improves when you have an exhaust fan drawing the steam out.
  • In your kitchen, exhaust fans reduce humidity, preventing mold from accumulating.
  • In addition to preventing the buildup of dangerous gases, it also provides the best ventilation.

How to Install an Exhaust Fan in the Wall?

With the right tools and a good understanding of the process, installing a through-the-wall exhaust fan is easy. Step-by-step instructions are given below on how to complete this task. 

You will need the following

Among the tools you will need for this project are a wire cutter, a reciprocating saw, a stud finder, a drill, and pliers.

Following are the steps

  • With a pencil, trace the outline of your exhaust’s circular housing. Utility knives are perfect for cutting plaster marks in the outline. 
  • To prevent your device from being blocked, use the reciprocating saw to cut through the wall’s insulation.
  • The siding on the outside can be removed with a utility knife. Following the square outline of the exhaust fan housing on the exterior wall, you will need to draw the border around it.
  • Sheathing around the exhaust fan should be removed using a reciprocating saw. Your exhaust fan must have a circular outline within the square outline you have drawn. 
  • Install the square housing of your exhaust fan using the screws included in the kit and your driver. There is nothing complicated about this step.
  • The next step is to connect your exhaust fan to an electrical outlet. Ensure that you have a constant electricity source. To connect the wires to the electric source, splice the ends of the sheathed wires together with your pliers. 
  • Connect the fan’s wire to the electrical box after you have put the fan’s circular housing in place. 
  • In this case, it is important to plug the fan into the electrical box and insert the fan into the housing.
  • To ensure that your device is working properly, test it after fitting the fan cover on.

Kinds of Exhaust Fans

A range hood or exhaust fan is one of the most common types of ventilation for kitchens and other rooms, but the layout of your kitchen may also determine which type is right for you. You can choose from the following options:

1. Under-cabinet Hoods

Typically, fumes and smoke are eliminated from the exterior of the building by mounting these underneath a wall cabinet and routing the ductwork through adjacent walls, chases, soffits, or ceilings. An upper kitchen cabinet can be opened to accommodate a shallow hood that comes with some exhaust fans.

It can take up a lot of cabinet space to install an under-cabinet hood, but it might be your only choice if your cabinet space is limited.

2. Wall-Chimney Hoods

Suitable for kitchens without cabinets over the cooktop, this type of hood works perfectly. Air is drawn from the inside to the outside by their vent stacks, which are usually mounted on the wall.

3. Island Hoods

Exhaust fans can be mounted on ceilings and vent through kitchen ceilings. In addition to being wider than your cooking surface, they should be located away from any walls or cabinets that may help funnel the smoke.

4. Downdraft Hood

In this type of hood, smoke and odors rise from your kitchen floor into ducts beneath the floor and are taken out in a reverse direction. If you can’t route ductwork through your kitchen ceiling, then this type of hood might be your only option as hot air rises, which makes it less effective for getting rid of smoke and steam.

5. Ductless Hoods

Smoke and steam can be directed away from a stovetop with these hoods that can be placed on islands, cabinets, or walls. They return to your kitchen after being directed away. Despite the filters’ ability to capture grease and oil droplets, smoke will still flow throughout the house and kitchen in spite of the filters’ capability to trap them.

Here Are Some Tips For Cleaning Exhaust Fans?

 Cleaning your exhaust fan properly is as simple as following these steps:

  • Pour boiling water over mesh filters on your kitchen exhaust fan if they are included. After soaking the mesh filters for about an hour in ammonia and hot water, mix half a cup of ammonia with one gallon of water. After you have scrubbed the filters, you can get rid of dirt better.
  • Use soap and water to clean the fan blades, or mix ammonia, baking soda, and warm water with 14 cups of ammonia to clean the blades. Wear rubber gloves and a mask to keep yourself protected while performing this task.
  • Are you looking for a way to get rid of grease buildup?
  • After scrubbing the fan parts with caustic chemicals, you should rinse them with hot water to remove the residue. In addition to chemical foam, garden sprayers or pressure washers can also be used to apply chemicals downstream.
  • Prior to applying any chemicals, use scrapers if there is a heavy buildup of grease. The dirt and grease can also be removed with a steam cleaner, then wiped off with a wet cloth or towel.
