5 Things to Look for Before Selecting an Exhaust Fan for Your Home

Exhaust fans are an indispensable addition to your home. They help maintain a healthy indoor environment, especially in areas such as the kitchen and bathrooms where moisture and odours accumulate rapidly. So, whether you are remodelling your home or simply looking to improve your home’s air quality, choosing the right exhaust fan would be your best bet. To make your search easy, we bring you an extensive range of innovative and energy-efficient exhaust fans, each designed to suit various needs. In this blog, we discuss 5 things you must consider to ensure you select the best exhaust fan for your home.

1. Determine the Appropriate Size

The effectiveness of an exhaust fan largely depends on its size relative to the room where it will be installed. Exhaust fans are rated by their ability to move air in cubic feet per minute (CFM). To choose the right size, calculate the volume of the room (length x width x height) and ensure the fan’s CFM rating adequately matches the room’s cubic footage. For instance, a bathroom exhaust fan should have 1 CFM per square foot of floor space at a minimum.

2. Consider the Fan’s Placement and Installation

Where you install the exhaust fan significantly affects its efficiency. In kitchens, the kitchen exhaust fan should be placed close to the stove to effectively capture and expel airborne contaminants. In bathrooms, the fan should be near the shower or bath area to quickly remove moisture. Installation is also a key factor:

  • Ceiling-mounted exhaust fans are common in bathrooms for direct ventilation through the roof.

  • Wall-mounted exhaust fans are suitable for kitchens and bathrooms with direct exterior access.

Pro tip: Ensure that the installation process aligns with your home's structure, and consider professional installation to guarantee that ductwork is properly connected and sealed.

3. Check Noise Levels

The operational noise of an exhaust fan is measured in sones. A lower sone rating means the fan operates more quietly. This is particularly important in spaces where silence is valued, such as bathrooms. Depending on your needs, you can consider an exhaust or ventilation fan with a rating of two sones or less to maintain a peaceful environment.

4. Evaluate Energy Efficiency and Additional Features

Modern exhaust fans come with a variety of features that enhance their convenience and functionality. You must look for models with energy-efficient motors that reduce electricity consumption without compromising on performance. 

5. Assess the Design and Aesthetics

Exhaust fans are available in a range of designs and finishes that can complement your home’s decor. We at Polycab, offer modern designer fans and exhaust fans in different colours and textures that seamlessly merge functionality with style. With a plethora of options, you can choose a design that fits seamlessly into the space without clashing with your interior design. For example, sleek, contemporary models in stainless steel or matte finishes work well in modern bathrooms and kitchens, whereas, traditional black or grey exhaust fans would be a perfect choice for traditional homes.

Conclusion

Choosing the right exhaust fan involves more than picking the most powerful option available. By considering the size, installation location, noise level, energy efficiency, and design, you can select a fan that effectively and efficiently meets your specific needs.
