How To Choose The Right Kind Of Exhaust Fan For Your Home

Posted by Freelancers HUB on

An exhaust fan is that best friend of ours who helps us out, but we forget to thank them. Jokes aside, home depot exhaust fans suck in smokes and fumes and put a stop to mildew formation. They are specially fitted in our kitchen so that they can drag out the spicy, nose and throat burning fumes along with the distinct odor. See, your exhaust fan really does a thankless job.

When buying an exhaust fan, people tend to make a few mistakes. First of all, it’s not a vegetable that you go to the store and buy. Second, an exhaust fan has many types and forms. So, we will learn about the exhaust fan types and how to choose the right one for you.

Types of Exhaust Fans

Choosing The Right Exhaust Fan

Ceiling Vented

Ceiling vented exhaust fans work by venting the fumes directly into the roof space. The roof should be titled and should contain enough space in the titles for proper ventilation. Ceiling vented fans are quite affordable and functional. However, like other types, this one isn’t entirely sealed, so there’s a chance for dust and dirt from the roof space to fall through the fan into the room. Another con is that you may lose heat from the room in winter and simultaneously gain heat in summer as the hole is open. To combat this problem, you can install backdraft shutters that will prevent the backflow of air and dust.

Heat, Light & Exhaust Unit

Although this type of exhaust fan arrangement falls into the expensive category, its functionality is okayish, not the best in the world. The heat, light, and fan attached set is a great way of incorporating some light and heat into your home space. It’s mostly used in kitchens and looks quite elegant and classy. If you want an exhaust fan with additional features like heat and light, this unit will help keep your room warm. You can find various styles with great ducting options.

Wall Mounted Exhaust

‍When your home has no concrete ceiling or ceiling cavity, a wall exhaust fan is a suitable option for you. Even if you install ceiling exhaust fans, there won’t be enough ventilation, and that’s why you should opt for a wall exhaust. These exhaust fans come with a pull switch or wires to plug in.

Window Exhaust

Window fans are a great addition to your bathroom, where there’s no room or space for a ceiling or wall fan. Window fans are installed in the window panel, which vents out toxic air. Window exhaust fans can be wired or be used with a pull switch. A downside to this type of fan is that you will need to cut a hole in the glass for the exhaust fan placement. Some glass types may need to be replaced to fit the fan as they can’t be cut once installed.

How To Choose the Right Exhaust Fan

Calculating The Suitable Output Capacity

The standard calculation of finding out which output capacity is preferable for the area of your room narrows down to how many times the air in the room needs to be replaced. For hot and congested areas like the kitchen and bathroom, you may need to replace the air 20 times per hour. But before calculating the air replacement, you need to calculate the dimension of your room first using the equation - length x width x height.

To make it easier, suppose your space is 5m in length x 4 m in width x 4m in height; the volume will be 80 cubic meters. Judging the space is congested and steamy, you need to turn over the air at least 20 times an hour, so multiply 80 x 20. As a result, you will get 1600 m³/h. So, 1600 m³/h is the minimum range for the fan. 

Consider The Type of Fans

Choosing the type of exhaust fans depends on the room you are investing the fan for. For ground-floor kitchens, you can opt for a wall or a window exhaust fan. Top floors can benefit from the ceiling, roof-mounted, or inline exhaust fans. In addition, you can attach exhaust fan parts like ducts and exhaust fan covers. No ventilation systems? No problem, you can install a light, heat, and exhaust fan combo set with switches for easier operations.

Don’t Forget The Energy Efficiency

Now comes the most crucial part, energy efficiency. You need fans that consume excessive electricity, and therefore it’s worth checking up on brands and comparing them. Always opt for the 5 Star Energy Efficiency label to make sure you are buying components that are energy efficient. You can do a quick google search and compare the prices, read the reviews before making up your mind on buying.

Select A Noiseless Exhaust Fan

When choosing an exhaust fan, always look for one that doesn’t induce noise. Sometimes, the best exhaust fan doesn’t equate to lesser noise. A quick way of finding out if your fan is noisy or not is by determining sones. The more sones your exhaust fan has, the louder your fan will be. For example, a fan with one sone will make less sounds than a fan with multiple sones. Also, learn to understand decibels or dBA to identify sound capacity. A fan with 35 dBA should be the one you should opt for.


So, with all things being said, you will by now know how to choose the best exhaust fan according to your home’s space.
