What is a Bathroom Exhaust Fan?
A bathroom exhaust fan is a device that helps to remove the moisture, odor, humidity, and other pollutants from the bathroom. It is ducted to the house’s exterior and sucks out the impure air from the indoors.
Benefits of a Bathroom Exhaust Fan
1. Reduced Odor
The bathroom is a breeding space for odor. Apart from the bacterial overgrowth caused due to human waste, clogged drains, dead skin cells, wet fabric, pieces of soap, dirty water, and other debris can cause a foul smell, which can grow over time and even transfer to other rooms.
A bathroom exhaust fan removes the air that smells bad and replaces it with fresh air. And as it does so, you may also be able to save costs on air fresheners.
2. Better Quality of Air
These days, toilet cleaners consisting of very aggressive chemicals such as sodium hypochlorite or hydrochloric acid are becoming popular. And while they help keep the bathroom clean, they also degrade the air quality and cause damage to skin, eyes, and throat.
A bathroom exhaust removes many harmful chemicals from the indoor air, helping your family to be healthier.
3. Removes Humidity
Humidity does a lot more damage than a foggy mirror. Excessive moisture is associated with conditions including dehydration, fatigue, muscle cramps, fainting, and even heat stroke.
In addition, mold can grow in highly humid conditions, damaging your bathroom hardware and even inviting pests like roaches and mites.
According to the EPA, the Relative Humidity inside a room should be between 30 to 50%, and an exhaust fan helps you to achieve that number.
Different Types of Bathroom Fans
Bathroom exhaust fans are available as ceiling and wall-mounted models. While both of them do the same thing, they have their own advantages and downsides:
As the name suggests, ceiling fans hang over the ceiling of bathrooms. There’s a vent on the ceiling, and the fan is directly above the vent. Moreover, the vent is connected to the exterior part of the roof.
The fan carries air out of the bathroom by creating a vacuum, eventually pushing the air through the vent to the outside of the walls. Often ceiling fans include lighting that can help brighten bathrooms or replace overhead lights.
- Easy to install
- More effective since hot air and steam rise directly to the ceiling
- Less noisy
- Requires more ducting during installation
- Can accumulate more dirt
- Since you need to put the vent on the roof, it’s more likely to be damaged by rodents or nesting birds
A wall-mounted fan hangs on the external wall of the roof and is generally used in cases where ceiling fans can’t be used, for example, on a second-floor bathroom.
Wall-mounted fans are preferred in mostly cold places. Since the vent is on the walls, it’s less likely to be damaged by the snow than when it’s on the roof.
- Can be ducted directly to the wall of the house
- Birds or other animals won’t be able to damage it easily
- Accumulates less dirt and is easy to clean
- Installation is straightforward and cheap
- Not as effective as a ceiling fan for the same amount of power
What to Consider When Choosing the Best Bathroom Fan?
Now that you know the basics of a bathroom exhaust fan, we’ll look at the things you should consider before buying one:
1. Airflow Capacity
The airflow capacity is the volume of air moved by the fan at a given time. For an exhaust fan, it’s measured in Cubic Feet per Meter.
According to the Home Ventilating Institute, rooms smaller than 50 sq ft. should have a fan with at least 50 CFM, while rooms between 50 to 100 sq ft. should have a CFM equal to the area of the room. For example, for an area of 75 square feet, you’ll need a fan with 75 CFM.
Similarly, for any bathroom wider than 100 sq. feet, you will need to choose the CFM depending on the fixtures in the bathroom. Refer to the table below:
For example, if the room has a shower and two toilets, you should provide: 50+(50×2)=150 CFM.
2. Noise Level
The unit for noise level is sones. The lower this number, the quieter the fan is while operating.
For reference, a quiet refrigerator is about 1.0 sones, and the noise level in a normal office environment is 2.0 sones.
The quietest bathroom exhaust fans have a noise level of about 0.5 or less. In this case, you won’t notice the fan running.
Fans with a rating of 3.0 will be as loud as a normal conversation. Finally, the loudest ones can be up to 6.0 sones.
Note: Some people may prefer noisier fans for extra privacy in the bathroom.
3. Energy Efficiency
Highly efficient bathroom fans come with an energy star certification. And energy star-certified devices are known to consume less than 70% of electricity than normal fans, allowing you to save heavily on operating costs.
But remember that fans with more features such as lighting and heaters can consume more electricity despite their energy star rating.
4. Installation Complexities
This can be overlooked, but the ease of installation is crucial for a good bathroom exhaust fan. As you can see, sometimes, the labor charge for installation can cost more than the fan itself.
Installing bath fans is complicated, as you will have to work with vents, wires, ducts, switches, and whatnot. This means you’ll need to hire professionals who have experience with everything, and it may take between four to eight hours for them to get everything ready for you.
Now, you can consider doing the installation yourself, but you’ll have to be careful if you don’t have prior experience- you may damage some components.
5. Duct Size
Apart from the fan itself, you should also need to know how to size the duct. Fans with more CFM need larger ducts since they’ll need to circulate more air. But it would help if you didn’t make the duct bigger than needed since you will only end up wasting space.
Most fans under 50 CFM fans will run well with a 4-inch duct. You will need at least 5 to 6 inches duct as you go higher. This also depends on the state requirements.
Remember, the duct size also affects the noise level. With bigger ducts, more air can circulate, putting less strain on the fan and making it quieter.
Finally, your fan’s design should complement your bathroom decor. In other words, you should buy a good-looking device that effortlessly blends in with the rest of the room and doesn’t stand out as an anomaly.
These days, many decorative exhaust fans are available that resemble light fixtures. Furthermore, multiple colors are available within the same model to match different room decors.
In this case, there’s no wrong answer- you’ll just have to get a fan you think is attractive and one that matches the current room design.
7. Additional Features
In addition to doing their usual task of removing moisture, some fan models may come with extra functionalities, including:
- Integrated lighting (overhead and night lighting) that can even replace the main lighting system of the room
- Built-in heater to add warmth
- Automatic humidity sensor, which opens the fan when the room is very humid
- Separate wall switch with controls customized specifically for the fan. This may consist of timers, condensation sensors, etc.
- Bluetooth to play music
- Motion sensor, which turns the fan automatically on when there’s a person in the room and turns off when the individual leaves the room.
How to Make Your Bathroom Exhaust Fan More Effective?
Finally, here are some other things to keep in mind to improve the effectiveness of your bathroom exhaust fan:
- Turn on the fan as soon as you start showering. Depending on the airflow capacity and the vent size, you may need to open your fan for up to 15 minutes after bathing to let the moisture escape completely.
- Clean the fan regularly (a couple of times a year) to remove any dust or grime from the duct or the motor. Remember to shut the electrical circuit while doing so.
- Remove puddles from the bathroom even when the fan is on to ensure that the floor dries up quickly and doesn’t accumulate mold or mildew.
- Ensure you don’t close the curtain or the door when the fan is open. As the moisture goes out of the room, it needs to be replaced with fresh air from the outside.
