What is a Bathroom Exhaust Fan?

A bathroom exhaust fan is a ventilation device that ducts out excess humidity from your bathroom. In a highly insulated bathroom, humidity tends to create an ideal atmosphere for mold and mildew to grow. With, the excess humidity and steam also begin to wear out paint from your bathroom’s walls, causing rusting on door knobs or even crack tiles. A quality wall mount bathroom exhaust fan can eliminate that humidity and replace it with fresh air.


A typical bathroom exhaust fan measures 14x15x10 inches. Hardly will you find a large bathroom exhaust fan. That’s because this fan is a simple device with a motor and a few other components. Its performance is determined by its ability to move air in cubic feet per minute (CFM). A small bathroom exhaust fan for, example, is one with a low CFM rating. Bathroom exhaust fans for bigger bathrooms will have larger CFM.


Bathroom exhaust fans cost considerably low compared to typical ventilation fans. They range between $50 and $200, with the most expensive fans having better performing features. A quality bathroom exhaust fan is, however, not necessarily expensive. Continue reading to learn more of why you need a bathroom exhaust fan.

Why do you need a Bathroom Exhaust Fan?

Excess humidity is bad for your skin, for your overall health, and for your bathroom. With a quality extractor fan, you can reduce this humidity and forever shower in a well ventilated bathroom. Bathroom extractor fans are also easy to affordable, easy to install, and durable. But most importantly, is that you will benefit from their services in the following ways.

  1. To Control Steam and Odors

    The work of a fan extractor is to remove smoke, steam, and odor particles from your bathroom or kitchen. A quality extractor fan will operate consistently and prevent much of the steam from causing damage to your walls and tiles. Since most drainage systems don’t eliminate odors, having a fan that can reduce unwanted smells will ensure you have a fresh bathroom every day.

  2. Heat Maintenance

    Some bathroom extractor fans feature heating elements that add warmth to your bathroom during cold seasons. Quality extractor fans also feature heat controlling mechanisms. This is meant to help maintain ideal bathing temperatures at all times. Heat maintenance is important especially with modern insulated bathrooms that can hold a lot of heat in them and potentially cause long term damages to your wall and tiles.

  3. Humidity Control

    Where else except for your kitchen do you experience high humidity levels? With all the steam and water particles in your bathroom, you can’t escape the humidity. And while humidity is not generally bad, too much of it is dangerous. Excess humidity in your bathroom can affect a sensitive skin. It can create a breeding environment for mold, mildew and potentially deface your bathroom walls.

    If you are like most people, you probably don’t enjoy the flu. Unfortunately, the flu virus thrives in humid places like your bathroom. Having a quality extractor fan can help keep you and your family healthy by keeping the flu virus off your bathroom.

Guide to Choosing the Best Bathroom Ventilation Fan

There is no doubt that buying a bathroom exhaust fan helps improve your bathroom. If you are not allergic to excess humid air, your bathrooms are. Excess steam and humidity damps them and wears out their beautiful paint with time. Fortunately, investing in a quality bathroom exhaust fan will defend you from the hurting drawbacks of steam in your bathroom. Here are the features and factors you need to ensure you get a high quality bathroom exhaust fan that will serve you for many years.

Air Flow Capacity

A bathroom exhaust fan is only as good as its air flow capacity. The air flow capacity determines how fast and efficient the fan is at a given bathroom. You need the right size of an extractor fan if you want excess humidity and odors of your bathroom. Bathrooms are measured in their ability to move air in cubic feet per minute (CFM).

The smaller bathroom exhaust fans register low CFM, while the more powerful extractor fans have high CFM. So, how do you know that an extractor fan is right for your bathroom? According to the Home Ventilating Institute, a single CFM rating represents one square foot in your bathroom. That means if you have a 100 sq. ft. bathroom, get a bathroom vent fan with a 100 or more in CFM rating.

Noise Level

One of the most important features of a bathroom exhaust fan is its noise level. No matter how powerful the extractor fan, you will most likely hate it if it is noisy. Noise level is thus, an important feature. It is even more important if you prefer to shower in a quiet, tranquil environment. Bathroom extractor fans’ noise level is measured in sones. One sone is the equivalent of a really whisper quiet refrigerator. If you find a low humming refrigerator still noisy, then you need to find an extractor fan with much less noise level. The lowest sone level is 0.3. Yes, there are bathroom exhaust fans that quiet. But they are more often more expensive. If you have no problem with white noise, invest in a fan with a sone level of 2 or 3.

Energy Efficiency

Everyone wants an energy efficient device. You probably are looking for the most energy efficient bathroom exhaust fan. Why anyway would want to buy an inefficient device? With bathroom exhaust fans, energy efficiency is measured in watts. A quality, energy efficient device is that which uses the least amount of watts. According to statistics, the most energy efficient bathroom exhaust fan uses a mere 3 watts. Average exhaust fans, however, use about 28 watts.

When shopping for a bathroom exhaust fan, buy one with an energy star. They usually are certified for having the best energy efficiency capabilities. Energy Star rated devices typically use 70% less energy. In most cases, these devices are less noisy too. Additionally, you gain a lot in energy bills when you buy an energy saving exhaust fan. Investing in the most energy efficient fan, for example, would save you seven times what the average extractor fan owner spends in a year.

Smart features

You gain a lot in a modern bathroom vent fan than someone who uses traditional extractor fans. There are a number of features you find in these high tech engineered fans that will make their maintenance easier. Some of the fans feature integrated lighting to help you reduce energy bills since you won’t have to switch on conventional lights anymore. If you invest in a fan with heating elements, you won’t have to worry about a cold bathroom during the winter season.

There are many more features with modern bathroom exhaust fans. You just have to look at those features that will help you the most. Humidity sensors, for example, are helpful features because they can sense when humidity levels increase. Some fans with motion sensors will only operate when someone gets inside the bathroom. This feature is helpful if you are concerned about energy consumption in your home. Finally, look for a bathroom exhaust fan with multiple functions and a control panel. A wall control panel ensures that you can manage all the helpful features in your extractor fan conveniently.

Bathroom Exhaust Fan Installation

Installing a bathroom exhaust fan is not a daunting task. If you installed your bathroom’s rainfall shower yourself, you shouldn’t have trouble with this. All you need to know is where to install it and get prepared to do some wall busting. However, if you are not sure about the job, hire a pro. You will have to pay double or even triple the amount you paid for the device itself. But that’s the price. Nothing good comes cheap.

Decisions to make

Before you have an extractor fan installed in your bathroom, consider the location to install it. The most ideal position is between your toilet and the shower head. It should also be close to the wall. The nearer the vent fan to the wall, the more efficiently it will perform. Note also that your bathroom should have a ventilation source besides this fan. Preferably, let your bathroom door have clearance on the lower end. This will ease the fan’s work and prolong its service life. Door clearance also brings in fresh air after the humid air is vented out of your bathroom.

  1. Step One: Drill a Small Reference Hole into the Ceiling or Wall

    If you purchased a ceiling mounted fan, drill a hole where you will install it. Draw a mark on the ceiling and then use a spade bit to drill a hole into the ceiling and attic. If you are using a wall mounted fan, drill a hole in the exact location where you want the fan installed. With this reference hole, measure up the fan’s vent size and bore a hole that size. When busting your wall, take caution to ensure that you only drill the required hole size.

  2. Step Two: Position the fan and Install it

    Position the fan through the holes on the ceiling and wall. Secure each bracket end with a drywall screw and work on the electrical connections. Follow the manufacturer’s instructions to ensure that you attach every part into its rightful position.

Bathroom Exhaust Fan Maintenance

Just as smoke and odors make a kitchen dull and unattractive, excessive humidity is the enemy of a beautiful bathroom. One piece at a time, excess humidity peels off the wall finish, causes rust on the door knobs, and increases odors in your bathroom. Humidity also offers a breeding ground for the flu virus, mold, and other unwanted pollutants. If you have a bathroom exhaust fan, you can avoid such damages by regularly maintaining it. This will ensure that it performs at its best at all times.

Cleaning the Grilles

If you own a new bathroom exhaust fan, you probably don’t need to uninstall it to check what is wrong with it. All you need to do is unscrew the grilles that protect the fan and vacuum clean them. If you still use the older models, you will need to add some oiling to your fan on a regular basis. Modern extractor fans don’t need oiling as they are permanently lubricated.

Cleaning the Vents and Ducts

One of the reasons why you need to install your vent fan properly is so that it vents out the mold and humidity out of the bathroom. Some fans tend to damp the moisture into your attic where mold and mildew get a breeding place. For regular vent maintenance, check the wall cap to ensure that is cleared of any bird nests and debris. If that area is clear but your fan performs inefficiently, check the attic. Many malfunctioning vent fans damp moisture into the attic instead of out of your walls. Also, check the duct to confirm that it is properly attached to the bathroom exhaust fan.

Bathroom Fan Cleaning Process

If you should decide to clean the whole bathroom exhaust fan unit, follow the following procedure

  1. Turn off the circuit breaker.
  2. Unscrew the vent fan cover or grilles. Some fan covers are not screwed, which should make them easy to use.
  3. Use a vacuum cleaner that has bristle brushes to clean the cover and grilles. Use a crevice tool to clean areas that are difficult to reach
  4. Ensure you clean the area around the motor and inside the wall cap by using a small paint brush or toothbrush.
  5. Reinstall the components you removed one at a time. Tighten the grilles properly or push the cover until it is firmly attached into place.

Bottom Line

If you love your bathroom as much as you love your living room, you should do everything possible to keep it looking stylish and livable. One way to do that is to invest in the best bathroom exhaust fan and to regularly maintain it. With a quality fan eliminating excess humidity and pollutants from your bathroom, the air in your bathroom will stay fresh and mold free. Fortunately, an extractor fan is not an expensive tool.
