While bathroom fans are typically very simple appliances, a lot of people still have many questions regarding how they work, how to maintain, etc.
In this section, we aim to cover some of the most common questions that most people have about their exhaust fans.
Frequently Asked Questions About Exhaust Fans
Q: How do I know the model of my exhaust fan?
A: Usually, there is a sticker found in the housing of the exhaust fan. All you have to do is locate the sticker, and you should be able to know what your exhaust fan’s model number is,
Q: Where is the ideal place to install my exhaust fan?
A: You have the choice to install it either on the ceiling or on the wall. Just make sure that it is close to the shower or the tub.
If you’re more concerned about odor, then you may also want to consider installing it near or right above the toilet bowl instead.
Q: What is insulation rating of an exhaust fan?
A: The insulation rating is an important part to know about your exhaust fan because it’s the aspect that helps prevent condensation in the duct.
You can check the model of your exhaust fan in order to know the insulation rating of your exhaust fan. The best bathroom fan models with lights and heaters are typically at the rating of R40.
Q: What’s the best way to clean an exhaust fan?
A: The fastest way is to use a vacuum cleaner with a brush attachment. Just take down the cover and vacuum it. After that, vacuum the inside of the fan including the motor and the fan itself.
Your fan should be very clean after that. To be totally sure, you can also wipe the cover and the fan with a damp cloth.
Q: Should I worry if my exhaust fan is leaking?
A: This kind of phenomenon is quite normal when the air is either too hot or too cold. But if it really bothers you, you can simply add more insulation to the ductwork so that you further minimize the condensation.
Q: What does CFM stand for?
A: CFM stands for Cubic Feet per Minute and it is a unit of measurement that’s used to measure the volume of air that comes from the fan.
This also helps you to ensure that your room is getting the right amount of air for its size.
Q: Should I get a fan with a heater?
A: Sure! Exhaust fans with heaters are great because of their multipurpose functions. Just make sure that you run the heater for only around 45 minutes at one time.
That’s more than enough time to ensure that your bathroom is warm enough for a comfortable temperature.
Q: What’s the cause of excess sound from the exhaust fan?
A: The main cause of this sound is either due to a loose motor or a loose fan blade. For the loose motor, just ensure that all the screws around the motor are tightly connected.
For the loose fan blade, make sure that the blade is tightly connected to the motor shaft. After you’ve checked both, test the fan to see if it works.
Q: How long should I leave my exhaust fan on after I take a shower?
A: We recommend that you leave it on for around 20 minutes. This should be enough time to make sure that the humidity in the bathroom is neutralized.
Q: Are there exhaust fans that come with timers?
A: Yes there are! Some of the best bathroom fan models all come with those timer features that allow you to control when your bathroom fan will start operating and when it’ll stop.
If you’re the type of person who doesn’t like to manually operate your fan, this is a rather useful feature.
Q: Is there a recommended duct size to get for my exhaust fan?
A: The duct size that you’ll get ultimately depends on the size of the exhaust fan you have. In order to know, get the CFM of the fan and ensure that the duct matches the CFM.
Q: Is there a formula to determine the size of the fan I should get?
A: The best way to compute your fan size is to first get the square foot of your bathroom (length x width). From there, multiply the square foot by 1.1. Then, you’ll be able to get the amount of ventilation needed for your bathroom in CFM.
So, if your bathroom is 150 square feet, multiply that amount by 1.1 and you’ll get 165 CFM. You’ll need 165 CFM for your bathroom.
Q: What are some of the best bathroom fan brands to consider?
A: Some of our favorite ones include Air King, Panasonic, NuTone, Broan, and Delta, among others, but you must also do your research to know which brands produce the products that best suit your needs.
