Advantages of Having an Exhaust Fan in Bathroom

Bathroom Exhaust Fan ReviewsYou would never guess how much of a change a bathroom exhaust fan can provide. Basically, it will have a huge influence on the air in the room. So, here are some of the biggest benefits you’ll enjoy with this type of unit:

1. It Reduces Moisture

Because you take hot showers and use so much water in the bathroom, the environment gets really humid. The biggest problem with this is that the walls and wallpapers might be damaged, and mold might also appear. Mold can be a drag to deal with since it’s hard to get rid of and can negatively influence the air quality.

Thankfully, installing an exhaust fan will help disperse a lot of the moisture, and let you use a bathroom that isn’t ruined by humidity.

2. Mirrors Don’t Get Foggy Anymore

Aren’t you tired of having to wipe the mirrors of the fog that forms after a hot bath? It’s annoying, especially since it leaves traces on the surface of the mirror. Wiping it will cause streaks too. Also, exposure to too much moisture isn’t beneficial for the mirror either.

Bathroom exhaust fans can help solve this issue too, so you’ll have the best fogless shower mirror.

3. Odors Won’t Be a Problem

Odors can be caused by a lot of factors, be it cooking, smoke, or anything else. But when you’re using the bathroom, it’s a shame if your experience is being tainted by a bad smell, and you have to hold your nose all the time. Since exhaust fans ventilate the air, they help get rid of bad scents too, automatically being a blessing in any bathroom.

4. Air Quality Improvement

Since such a unit can keep mold and mildew at a distance, you can rest assured that your asthma or allergy symptoms won’t be triggered. All it takes is a high-quality exhaust fan, and the problem will be as good as gone.

How to Size a Bathroom Fan?

Best Bathroom Exhaust FanWhen it comes to choosing a bathroom exhaust fan, you have to take into consideration the size. However, size doesn’t refer only to the actual dimensions of the fan – it also includes the power or the amount of air it’s able to move.

To determine this, one must take a look at the cubic feet per minute. If you have a smaller bathroom, which is 100 square feet or lower than that, a standard-sized exhaust fan is what you should settle for. Normally, you need one cubic foot per minute per square foot. So, you have to find out the square footage of the bathroom to make sure you choose the right size for your exhaust fan.

In order to do that, the “secret” is to multiply the length of the room times the width. Sometimes, you can oversize the fan and get better power, making it more convenient.

In certain situations, though, you might have a large-sized bathroom – which means that a standard-sized exhaust fan would not be enough. A large bathroom means one that is above 100 square feet.

To calculate the size of the suitable exhaust fan for your bathroom, what you need to consider is the number of fixtures you have there. The formula involves adding up the CFM ratings for all the fixtures in the room. For example, 50 CFM for the toilet, 50 CFM for the bathtub, and so on.

If all you have in the bathroom is the toilet and the shower, then a 100-CFM fan should be enough. Meanwhile, if your bathroom has some additional fixtures like a jetted tub, combined with the toilet and shower, you’ll need a fan of 200 CFM.

Keep in mind that if you have a bathroom with an enclosed shower or toilet, installing multiple exhaust fans might be the best course of action.

Bathroom Exhaust Fan Buying Guide

Bathroom Exhaust Fan Buying GuideBathroom exhaust fans may not be rocket science, but if you’ve never had one before, or you made a wrong choice, it might be hard to know how to find a good one. This is why, in order to pick something qualitative, there are some aspects to keep in mind. Here is what you should pay attention to:

1. Durability

As you’ll be able to see from our homepage, durability is an important aspect for bathroom appliances. One of the worst things that could happen is to end up with an exhaust fan that breaks apart in a very short amount of time. You spend money on it after all, and even if the product has a warranty, it’s still not pleasant to see it break down. For this reason, you should always look for specific features to ensure the fan will resist humidity and other factors.

See whether the casing of the fan is made of galvanized steel or not, and make sure that the motor is always lubricated. Likewise, ensure the exhaust fan is able to sustain the humidity. The best thing to do is to check the features, but also the reviews of the product, so you know if the benefits are actually true.

2. Noise

Everybody hates an appliance that sounds like a helicopter about to take off. It’s not pleasant, and it isn’t only deranging for your ears, but might also distract you from certain things. So, preferably, you should look for exhaust fans with low noise levels.

For exhaust fans, the noise level is generally measured in sones. So, the lower the sones number, the less noise the unit generates. Make sure you choose wisely.

3. Exhaust Fan Combo

Wouldn’t it be cool if an exhaust fan had more features apart from circulating the air in the bathroom? Well, that’s a thing. There are light/fan combo exhaust fans that not only get rid of humidity and odors by moving the air around, but also have a light bulb to brighten the area when you need to use it.

If you tend to take trips to the bathroom during the night, it might be better to have this as a light source than the actual lighting system. It’s softer and won’t hurt your eyes. It can also totally change the mood in the bathroom.

4. Mounting

You want a unit that is easy to mount, but that all depends on your bathroom and your preference. When it comes to mounting, there are two options for bathroom exhaust fans: wall and ceiling installation.

But you need to know that the ceiling is able to support the weight of the appliance, so you don’t end up ruining anything. Take the fan unit’s construction, as well as the bathroom’s construction into consideration before you decide the type of mounting for your exhaust fan.

5. Additional Heater

Additional HeaterA few exhaust fans out there also come with a heater. More often than not, you end up feeling a little cold after a shower, or the bathroom itself gets cold during the winter. It’s not too pleasant, which is what makes a heater such a wonderful extra to an exhaust fan.

So, if you were in need of the best bathroom heaters anyway, it would be a wiser decision to have an exhaust fan that has this feature. This way, you don’t have to spend money on two separate appliances.

6. Warranty

Since some appliances might stop working early on, it’s frustrating to have to spend money on reparations. So, it’s always essential to have some sort of protection against damages and anything of the sort. In this case, you must look for a warranty.

A warranty will promise you durability for the item for a long time to come. But you should be careful what type of warranty you settle for. Some of them are shorter, of 1-5 years, but they do have a lot of advantages – guaranteeing the durability of the case and any other component.

There are also lifetime warranties, but these might be less convenient because they don’t cover all the parts.

7. Energy Consumption

When installing a bathroom exhaust fan, the last thing you want is to spend more on electricity. Especially if you’re on saving mode, it’s ideal to find something that doesn’t consume too much power. Check the specifications of the product to see how much it consumes, and check the reviews too, as they might mention it.

Also, make sure you don’t assume an exhaust fan has lower power consumption simply because it has a smaller size compared to another. Size is not an indicator of how much the appliance consumes. Choose wisely and you won’t end up with something that “devours” too much electricity.

8. Aspect

Normally, it doesn’t really matter how your exhaust fan looks. What good does it do if you have an amazing looking fan with poor performance? Still, you may not want to settle for the ugliest unit you can find, especially if you have a beautiful, delicate décor in your bathroom and don’t want to ruin it.

The color and finish of the exhaust fan must be considered in this scenario. Some fans have a rather modern aspect to them, while others go for a more traditional, or elegant look. It might seem weird to think about it, but there really are many options to choose from in terms of design.

There’s an exhaust fan for any bathroom, so if you have the time to go on a search for the most aesthetically pleasing fan-operating unit, don’t hesitate to do so.

9. Motion Sensor

If you want the exhaust fan to only work while you’re in the bathroom, you can look for one that has motion sensor activation. This means that whenever someone walks into the room, the device will sense the movement and start operating. This can help you save on energy while ensuring that the unit does its job.

How to Install a Bathroom Exhaust Fan

How to Install a Bathroom Exhaust FanUsually, the installation of a bathroom exhaust fan is not that difficult, but it all depends on the unit you have. If you install it yourself, you must be very careful as you’ll have to wear a respirator or dust mask while standing on a ladder. But at the same time, it’s not the most difficult thing you’ll have to deal with.

Once you have all the tools, here is what you need to do:

1. Find a Tubing Route

It’s essential for the air-ventilated by the unit to be expelled outside the house. Thus, you must be able to access the attic to install the tube. So, check to see where the attic door access is, and go there by climbing up the ladder. Don’t forget to flip off the circuit breaker before you do so, though.

2. Find the Power Source

You will have to connect the exhaust fan to electricity, which is why finding the power source is vital. See if power is running to the point where you want to install the appliance. See what the local electrical code is too. Sometimes, you might share the lighting circuit with the fan, while other areas have you running new circuits.

3. Find the Vent Location and Secure It

As mentioned, air needs to be eliminated out of the house. Find a location for it as you’ll have to run a duct from the unit. Once you find the perfect spot, cut the vent location after scribbling the shape around the cent cap. Cut the shape with a saw, and attach the vent with screws.

Afterward, secure the fan to the joists. Don’t forget to also route your unit to the exterior next.

4. Attach the Fan to its Housing

Now, it’s time to insert your exhaust fan into its housing, which means you will also have to deal with the electrical wiring process. When you’re done, attach the fan grille and turn the circuit breaker on.

FAQ About Bathroom Exhaust Fans

A lot of people still have curiosities when it comes to bathroom exhaust fans, and you might be one of them. If you need some additional information to make sure you’re using the fan properly, here are some of the most frequently asked questions on the matter:

1. What to do if the water is dripping from the exhaust fan?

First of all, it’s important to establish the cause of the problem. If there’s a colder climate, the roof or wall cap will have ice forming on it. As such, when hot air starts to circulate the area, the ice will melt and come out of the appliance. Make sure to look for a wall cap that has a backdraft damper.

Sometimes, the issue can occur because condensation might happen due to the hot air traveling in the cold ducting. You will have to wrap some ductwork with insulation, so this doesn’t happen anymore.

2. Do I necessarily need an electrician to replace or install my fan?

You don’t have to call an electrician to replace or install the fan if you know enough about electricity yourself. But normally, it’s recommended to have an expert check and see whether the unit is working properly, and it doesn’t pose any dangers. Since there is some wiring included when installing an exhaust fan, it’s better to be safe than sorry.

3. Is it dangerous to install my exhaust fan above the shower or the bathtub?

It all depends on the type of exhaust fan you purchase. Some of them are safe to install in such places as they are UL certified. So, you should always make sure this feature is listed. Concurrently, if a fan has another type of heating, it might not be fit to install above your shower or bathtub. In any case, you should carefully check the features of the product to make sure you know what to do.

4. Does my exhaust fan need cleaning?

Yes, exhaust fans will need regular cleaning, given they take moisture out of the air and eliminate it outside. Otherwise, mold might end up forming inside the fan, and it will still be toxic in the bathroom.

To do this, turn off the power first so you’re safe. After that, you should use a soft cloth and mild detergent to clean the grill of the exhaust fan. When you’re done cleaning it, try to dry it completely before you put it back to work. You don’t want to put a wet fan to operate since it’s an electrical appliance.

Also, a vacuum might be used to get rid of the dirt accumulating in the fan assembly as time goes by.

5. Why is the air moving so slow, even if my exhaust fan is operating?

Sometimes, build-up might prevent the air from moving properly, and you end up getting little ventilation, or no ventilation at all. This is one reason why you need to regularly clean the build-up.

Wrap Up

Finding the best bathroom exhaust fan can put you in a tough spot unless you have some experience with these units. You have to look carefully and analyze each product before coming to a conclusion. Our buying guide should have offered you enough information on the subject, and the process should be much easier to go through.

Now that you’ve read all the bathroom exhaust fan reviews, as well as the buying guide, installation information, and advantages, you should know how to choose. Hopefully, you’ll get the right exhaust fan and get rid of the excess humidity in your bathroom.
