Tips for Buying Bathroom Exhaust Fans
Bathroom exhaust fans are an essential part of any bathroom, as they provide much-needed ventilation, eliminate unpleasant odors, and prevent mold and mildew growth. Choosing the right bathroom exhaust fan can be a daunting task, with so many types, sizes, and features available in the market. In this article, we will discuss some tips for buying bathroom exhaust fans and provide a detailed description of the four types of bathroom exhaust fans, their key features, and benefits.
What are Bathroom Exhaust Fans?
Bathroom exhaust fans are ventilation systems that help to remove moisture, odors, and pollutants from the bathroom air. These fans work by drawing in humid air from the bathroom and expelling it outside, either through a duct or a vent. The primary function of a bathroom exhaust fan is to improve indoor air quality, prevent mold growth, and reduce the risk of health problems associated with poor indoor air quality.
Buying Bathroom Exhaust Fans – Types
Wall Mount Exhaust Fans
Wall-mounted exhaust fans are installed on an exterior wall of the bathroom and vented outside. These fans are ideal for bathrooms that do not have a ceiling vent. They are available in different sizes and airflow capacities, and some models come with a built-in light, making them a convenient and efficient option for small bathrooms.
Ceiling Mount Exhaust Fans
Ceiling-mounted exhaust fans are the most common type of bathroom exhaust fan. These fans are installed in the ceiling and vented outside through a duct. They are available in various sizes, shapes, and airflow capacities, and some models come with built-in lights, humidity sensors, and timers, making them an ideal choice for larger bathrooms.
Inline Exhaust Fans
Inline exhaust fans are installed in the attic or ceiling space and connected to the bathroom through ductwork. These fans are designed to be quiet and efficient, making them an excellent option for large bathrooms or bathrooms that require extended duct runs. They are available in different sizes and airflow capacities and can be used to vent multiple bathrooms with one fan.
Window Mount Exhaust Fans
Window-mounted exhaust fans are installed in a bathroom window and vented outside. These fans are easy to install and do not require any ductwork. They are ideal for bathrooms that do not have a ceiling vent or for those who want an easy-to-install option. They are available in different sizes and airflow capacities and can be an affordable option for small bathrooms.

Tips for Buying Bathroom Exhaust Fans
Determine the Size
The first step in choosing a bathroom exhaust fan is to determine the size of the fan you need. The fan’s size should be based on the bathroom’s square footage and the air volume of the fan, measured in cubic feet per minute (CFM). A general rule of thumb is to choose a fan that can move at least 1 CFM per square foot of the bathroom’s area.
Noise Level
The noise level of the fan is an important consideration, especially if you have a small bathroom or a bathroom that is located near a bedroom or living area. Look for fans that have a noise rating of less than 1.5 sones, as these fans are quiet and unobtrusive.
Ventilation System
Depending on the location and layout of your bathroom, you may need to choose a specific type of ventilation system. For example, if your bathroom does not have a ceiling vent, you may need to choose a wall-mounted or window-mounted fan. If you have a large bathroom, an inline fan may be a better option.
Energy-Efficiency
An energy-efficient bathroom exhaust fan will not only help to reduce your energy bills, but it will also reduce your carbon footprint. Look for fans with the ENERGY STAR label, which indicates that they meet strict energy efficiency guidelines.
Mounting Type
As mentioned earlier, there are four main types of bathroom exhaust fans: wall mount, ceiling mount, inline, and window mount. Consider the layout of your bathroom and the placement of the existing vent when choosing the right mounting type.
Extra Features
Some bathroom exhaust fans come with extra features, such as built-in lights or heaters. These features can be useful in certain situations, such as when you want to add extra warmth to your bathroom during the winter months.
Check the Warranty
Finally, always check the warranty before purchasing a bathroom exhaust fan. Look for a fan with a lengthy warranty, as this indicates that the manufacturer stands behind their product and you’ll be covered if anything goes wrong.
FAQs
What is the ideal size for a bathroom exhaust fan?
The ideal size for a bathroom exhaust fan depends on the size of your bathroom. As a general rule of thumb, it is recommended that your fan should be able to move one cubic foot of air per minute (CFM) for every square foot of your bathroom. For example, if your bathroom is 100 square feet, your exhaust fan should have a CFM rating of at least 100.
Can a bathroom exhaust fan also be used as a heater?
Yes, there are bathroom exhaust fans available that also double as a heater. These units are especially useful for colder climates where having a warm bathroom is important. Make sure to check the specifications of the exhaust fan before purchasing to ensure it meets your heating needs.

Can a bathroom exhaust fan help reduce mold and mildew?

Can a bathroom exhaust fan be loud?
