Are Bathroom Fans Required

A bathroom is an essential place where most people go to relax and meditate. While in the bathroom, you not only bathe to get clean but you also allow the hot steam to surround you and create a relaxing mood. Although this experience creates a great feeling for you, leaving too much steam in the bathroom can be disastrous as it can easily damage the walls, the bathtub, the shower curtain, and the tiles if you’re not careful.

Excess moisture or steam in the bathroom actually raises the humidity levels, creating a perfect environment for mold, mildew, and microorganisms to multiply. Apart from damaging the walls, the curtains, the tiles, and the bathroom doors, this moisture puts your family’s health in jeopardy if it’s not taken care of at an early stage.

Now, having said that, one of the best remedies every homeowner should think of when tackling such a setback is through installing a ventilation exhaust fan. Depending on the design of your bathroom, some people may have considered building the house with large windows which when opened can help eliminate bad odors, steam, moisture, and humidity. Although windows do help in eliminating stinky smells and humidity from the bathroom, most professionals advise homeowners to consider installing exhaust fans as they remove fumes and odors much faster than open windows.

Are Bathroom Fans Required?

Bathroom fans are much more reliable than windows because they depend on the ductwork to suck odors from the bathroom then push in fresh air from the room. This circulation of air is the main reason why most people prefer installing exhaust fans over just having windows.

Bathroom fans are also more reliable than ever before. Today’s bathroom fans are more versatile as they offer you the opportunity to ventilate, warm, and light up the bathroom using the available independent switches. These fans are affordable, relatively silent while operating, and they consume less power as compared to older units.

By calling a professional technician to fix the unit, you’ll be able to enjoy the vast benefits offered by today’s bathroom fans anytime you take a hot shower. Now, having said that, this post will highlight four key benefits of bathroom fans that will answer your question of whether or not they’re required in your bathroom.

Eliminates mold and mildew

I believe you all enjoy breathing fresh air right? One way of welcoming freshness in your rooms is through ventilating your house or office to allow precise air circulation throughout the place. According to most professional doctors, mold and mildew are some of the major causes of most diseases. When you’re not breathing fresh air, you’ll not only get sick, but your mind will not be in a position to function well.

Mold and mildew mostly breed in poorly ventilated areas where there’s excess moisture in the air. One such place is the bathroom. If you’re keen, I believe you’ve once seen black build-up around the tub, the tiles, and on the walls. This kind of mold is very dangerous when inhaled and can cause severe health issues if prolonged. Now, the reason why a bathroom fan is required in such a situation is to suck up moisture, steam, and odors from the bathroom, leaving it fresh to avoid the breeding of such bacterium.

Gives the room a fresher scent

If your bathroom smells, then it doesn’t create a peaceful environment. As I stated earlier at the beginning of this post, the bathroom is the perfect place where you can sit and relax your mind. Now, to ensure that you enjoy your time while in there, the place needs to be fresh and free from stinky odors. To achieve this, install a bathroom fan that will not only warm up the room but will also allow continuous circulation of fresh air. When the air is clean, it gives you the confidence of even hosting high profile visitors as you’ll not have anything to be embarrassed about.

Reduces the maintenance cost

Another reason why are bathroom fans required is because it reduce the overall cost of maintenance caused by humidity. With excess humidity in the bathroom, your walls will start to deteriorate while the paint will peel off, causing discoloration on the ceiling and the tiles. To ensure that you don’t get to such a point, a bathroom fan will need to be installed as it will ensure that any humidity build-up within the bathroom is eliminated with ease.

Bottom line

As I conclude, I would highly recommend all homeowners to consider installing bathroom fans in their rooms to get rid of bad odors, steam, and humidity as they can cause mold and mildew. Bathroom fans are affordable, easy to install, and they’re power efficient, meaning they don’t consume a lot of electricity. Most of them come with three in one functionality where they not only ventilate your bathroom, but they also warm up the bathroom and provide sufficient lighting to make bathing a little more fun.

Can Bathroom Fans be Installed in a Shower

Can Bathroom Fans be Installed in a Shower

A ventilation system is an essential addition that makes your bathroom better than ever before. A bathroom without a fan is like a fireplace without a chimney. If the fireplace doesn’t have a chimney, then smoke is likely to spread throughout the house making you uncomfortable instead of providing you with warmth. On the other hand, a bathroom fan allows your bathroom to stay cool, aerated and highly ventilated to avoid mold and mildew buildup.

Bathroom fans are designed to suck out moisture, steam, and odors from the bathroom. If the room is left unattended for long, mold and mildew build up will be expected to take over, causing serious damage to the walls, the painting, the roof, and the tile floor. However, due to their complexity, most people may be wary of installing bathroom fans in their rooms and may prefer other methods such as buying fresheners and opening bathroom windows for precise air circulation.

Can bathroom fans be installed in a shower?

Like we explained in the other articles, bathroom fans are very important when placed in the bathroom ceiling as they help in sucking out bad odors, smells, steam, and moisture. Once your bathroom is ventilated, damages caused by mold and mildew will be largely minimized leading to low costs of repair.

How are fans related?

Before we move on, I would like to explain how fans are measured. Now, when buying a bathroom fan, there are two major factors you need to consider which include the strength of the fan (measured in CFM, and the noise rating (measured in sones) and.

CFM—which stands for Cubic Feet per Minute—is a measurement that’s used to rate the strength of a fan. On average, most fans have a CFM rating that ranges from 50 all the way to 1,000. For those who don’t have an idea on which type of fan to buy, always check one with a CFM rating of less than 200 to avoid spending much on power.

Next, we have the noise meter. Measured in sones, the noise meter ranges from 0.5 all the way to 4.0 depending on the type of fan you’ve installed. Most people may prefer installing silent motors with a noise rating of 0.5 to 2.0. However, there are some homeowners who may prefer noisier alternatives (ranging from 3.0 to 4.0 sones) as a way of providing privacy against toilet noises.

Finally, when purchasing a bathroom fan, it’s important to understand that CFM and sones are related at some point. You see, a powerful fan with a higher CFM will obviously be expected to produce more sound while a weaker fan with a lower CFM will produce less noise due to the low suction power.

Which is the best location to install a bathroom fan?

Now, having said that, let’s answer this question of whether a bathroom fan can be installed in the shower. To answer this question, let me say that bathroom fans are intended to be installed in the ceiling to allow precise suction of moisture from the bathroom. When choosing the best location to install a fan, you need to consider the perfect location where the fan will accomplish its mission easily and a location where the ductwork will run efficiently.

The primary objective of a bathroom fan is to suck out as much moisture as possible from the bathroom. Therefore, a fan should be located in an area where the most moisture, steam, and odor are likely to accumulate to. In this case, areas above the shower or the bathtub will be perfect. If your bathroom only has a shower, then the fan should be installed in an area over the shower. On the other hand, if your bathroom has a shower and a bathtub or a whirlpool tub, then the fan should be installed in between the two to allow perfect suction of moisture and steam from the bathroom.

Something else you should be keen on when installing a bathroom fan is the location of any available intake air source. In this case, we’re talking about the windows and the doors. To allow fresh air movement throughout the room, ensure that the bath fan is located away (at least five to eight inches) from the window or the door.

If you have multiple bathrooms in the house, then you should consider installing independent fans in each room to allow precise air circulation. In case of a toilet, it would be better to install a noisier fan to maintain the privacy due to toilet noises. With that being said, I believe that you’re now fully informed of the best location to place a bath fan and which type of fan is the best to consider.

Do Bathroom Fans Blow Outside

Do Bathroom Fans Blow Outside

If you’re a professional technician, it’s quire probably that your client (a homeowner) might have curiously asked you this question. In fact, those people who know nothing about ventilation will have to ask this question to understand the mechanism and mode of operation of bathroom fans. In reality, bathroom fans are designed to vent in various ways depending on how a house is built. For instance, if a house is designed with cathedral-like ceilings or maybe the lighting system has occupied all the space above, alternative ways of fitting a fan (let’s say on the wall) will have to be considered. On the other hand, if the roofing system is different (maybe there’s less space in the attic), then an alternative method of venting the room might be considered.

Bathrooms are particularly prone to mold and mildew caused by humidity. When heat and moisture combine, a room with less ventilation is likely to have damage to the walls, the ceiling, and the floors. In addition to that, a poorly ventilated bathroom is prone to bad odors and stinky smells caused by damp towels and wet clothes. Therefore, to counter such problems, a bathroom fan is the perfect solution as it ensures that bad odors and stinky smells are eliminated with ease, allowing precise air circulation to go through.

Just to note, when buying a bathroom fan, some of the essential factors you need to check on are the price and the rating of the air movement which is measured in CFM (cubic feet per minute). The basic CFM rating of most fans is 80 CFM which is considered to be silent, energy efficient, and perfect for indoor use.

What’s the purpose of the bathroom fan: Do Bathroom Fans Blow Outside?

Before we move on into details, we need to explain the purpose of the extractor fan to those customers who don’t know much about them. A bathroom fan is designed to suck out air from the bathroom and blow it right outside through the ductwork fitted on the ceiling. Just like how a kitchen range hood operates, a bath fan functions through sucking, only this time it’s used for sucking out moisture not smoke.

Although most people may consider bathroom windows, a bathroom fan is more preferable as it sucks out bad odors and allows fresh air to flow into the room for efficient air circulation. Mold and mildew can really cost you a lot if you’re not careful. Therefore, installing quality bath fans on the ceiling will save you a lot when it comes to keeping the bathroom fresh as well as the walls, ceiling, and tile floors.

How do you install a bath fan?

Bath fans are designed to vent outside. The reason for this is to allow continuous air flow through the room. However, there are several different ways to which a bathroom fan can be installed to ensure that it works optimally. Some people may consider venting to the attic while others prefer venting outside through the roof. In this section, we will highlight the different ways of venting a bathroom fan.

Through the wall

One way of venting a bathroom fan is through the wall. Let’s take an example of a multi-story building. In such a situation, you won’t expect a fan to be placed on the ceiling as there’s no space due to the concrete slab above. Also, the location of the bathroom might make it difficult to place the fan on the ceiling, forcing you to consider an alternative method. To ensure that a bathroom is ventilated well in such a situation, venting through the wall is the best option where the ductwork is done on the sidewall right outside to the vent.

Venting straight up

This is the most common method of venting a bathroom. Venting right up involves fitting the bath fan on the ceiling, then allowing the ductwork to go right up through the roof to the vent above. This method is ideal for bungalows or those houses with perfect bathroom designs that are very easy to ventilate.

Don’t vent in the attic

Another method of venting is through the attic. This method is highly considered by a majority of homeowners. Venting through the attic is a kind of a shortcut and should not be considered as it can damage the roofing system in your house or cause leakage through the ceiling.

When hot moisture or steam is vented through the attic, it begins to condense due to a change in temperature. During cold weather, the hot steam from the bathroom is condensed to match the cold temperatures outside. When this happens, the attic tends to “rain” inside. The water is then absorbed by the roof, leading to rotting of the wood and eventually serious damage to the roofing system will be seen. To avoid incurring such expensive repair costs, ensure that you ventilate your bathroom in either of the above two methods to ensure that you allow precise air circulation without exposing your roof to any dangers.

Do Bathroom Fans Get Rid of Smells

Do Bathroom Fans Get Rid of Smells

Have you ever used the bathroom at some point only to be completely embarrassed by the amount of foul smell you’ve left behind? Have you also walked into a friend’s bathroom only to be welcomed by a stinking smell due to the clogged dampness inside? Well, these are the two main reasons why proper ventilation is necessary for every bathroom. Most people may not understand the importance of installing a bathroom fan in their homes but the minute you host your colleagues, friends or family members for a night party, I believe you’ll see the real importance of having such a gadget installed in your home.

There are two major categories of bathroom de-smelling which require you to install a bathroom fan with ease. One of them is instant (emergency) while the other is atmospheric. The former involves using the bathroom/toilet then you realize you need a faster mechanism of sucking out the bad odor while the latter involves ventilating the bathroom to eliminate dampness, moisture, and common bathroom scents.

Do Bathroom Fans Get Rid of Smells?

Most beginners in the world of bathroom fans have been asking this question over and over again—do bathroom fans get rid of smells? The answer is YES. Bathroom fans are the most efficient ventilation units that keep your bathroom fresh and free from bad odors, smells, and common bathroom scents. For them to be effective, bathroom fans need to be installed well with the help of professional technicians to avoid any errors. During operation, these fans allow a continuous flow of fresh air from the roof into the bathroom through the vents and the ductwork installed in the attic. Today’s bathroom fans are energy efficient and versatile enough to operate both as fans and warmers.

First, let’s highlight some alternative ways of eliminating smells

Before we move on, let me state that most homeowners have considered alternative ways of eliminating bad smells from their bathrooms. Among the common methods used by majority of the people include:

Vacuuming

The majority of home occupants have considered vacuuming their bathrooms using the available upholstery attachments. Using scented soap products, such people have considered vacuuming the bathroom tiles from the floor, the walls to the ceiling leaving the entire room fresh and scented.

Using baking soda

Other homeowners have considered testing the magic behind baking soda. According to their report, sprinkling baking soda throughout the ceramic/tiled floor then leaving it overnight helps in absorption and elimination of bad odors without facing any difficulty.

Scented candles

Other homeowners believe in the power of scented candles. Such candles (especially those made with essential oils and fragrances) aid in deodorizing the bathroom, eliminating all bad odors with ease. Most people prefer going for those floral or citrus oils due to their strong scents. Essential oils are perfect because they offer vast health benefits to your body when inhaled.

Scented sprays

This is one of the most common methods used by a majority of homeowners to get rid of bad smells. Air fresheners are designed to be used in bathrooms to eliminate level one scents when someone uses the bathroom. Although they offer the perfect way of deodorizing the bathroom, they’re not recommended for asthmatic people or those who are allergic to strong scents.

Bathroom vent fans

Finally, we’re back to our topic. Although all the above methods are perfect ways of eliminating smells from a bathroom, they all have at least one or two health disadvantages to the user. Due to this reason, a bathroom fan is the perfect way of ventilating a bathroom to keep it fresh and free from odors.

The position of the fan

Before installing a bathroom fan, one thing you need to keep in mind is the location. Where are you planning to install the fan? By logic, a bathroom fan is supposed to be installed in the upper part of the room. However, most people do not know the reason why. You see, when using a bathroom, there will be hot air caused by the steaming water. Warm air rises upwards so with a perfect fan already installed close enough to the ceiling, the hot air will be sucked in, leaving the room cool and fresh.

Final thoughts: Do Bathroom Fans Get Rid of Smells?

Now that we’ve explained everything you need to know about bathroom fans, I would personally recommend this method to all homeowners. Although some people may consider alternative options as the ones highlighted above, a bathroom fan will remain to be the only reliable method due to its efficiency, versatility, and simplicity.

Do Bathroom Fans Use a lot of Electricity

Do Bathroom Fans Use a lot of Electricity

This is one of the most common questions asked by a majority of homeowners. Today, following an increase in the cost of electricity or energy at large, one question every buyer must ask himself when purchasing any electrical appliance is the energy efficiency or the cost of operation. Depending on the quality, the intention, and the type of bathroom fan you’re intending to buy, you’ll notice that the cost of electricity will vary greatly.

Bathroom fans are essential, especially for those people living in extremely hot areas. During summer, temperatures rise to unforgiving measures, making you feel uncomfortable when working or doing your daily chores. To combat such setbacks, one way is through installing bathroom fans to aid in eliminating excess humidity as well as support precise air circulation throughout the room.

Types of fans: Do Bathroom Fans Use a lot of Electricity?

The rate by which bathroom fans consume energy greatly depends on the type of fan you’re using. Unlike in the past where fans were binary, today’s units are classic and more versatile, allowing you to enjoy more options than ever before. With that being said, let’s go through a number of common bathroom fans available in the market and see how each one of them consumes electricity.

Table fan

A table fan is one of the smallest, cheapest and readily available types of fan you’ll find in the market. Designed with a base at the bottom to keep it upright, this type of fan releases short bursts of cool wind towards the surrounding area, keeping the room fresh and free from odors. Due to its small size, this fan is powered by a small capacity motor meaning it doesn’t consume a lot of electricity.

Tower fan

This type of fan is quite unique as it’s designed with the shape of a tower. Operated by a motor, this fan also allows a precise circulation of air throughout the room thus eliminating bad odors and smoke. Apart from ventilating the room, this type of fan comes with additional features that include filtration and ionization making it usable in various situations.

Ceiling/Bathroom fans

This type of fan is mostly found in bathrooms and is designed to eliminate odors, dampness, and smells. Available with a powerful fan mounted on the ceiling, this unit works by sucking out bad odors, steam, and moisture from the bathroom to the open air above. This type of fan is designed with a large motor and it’s the most expensive due to its three in one functionality (fan/warm/light).

Calculating the cost of running a bathroom fan

Back to our main question; let me mention that the rate by which bathroom fans consume electricity greatly depends on a few factors that include the size of the motor, the features, the speed settings, and how frequently the motor is used.

Electrical appliances are usually measured in watts. Each bathroom fan must have a watt rating, a voltage rating, and an ampere rating. Usually, the larger the motor, the faster it will need to spin, hence the more watts it will consume. In the table below, I will explain deeper supposing we have a three-speed fan with a maximum output of 45 watts and an electricity usage rate of 28.7c/kWh.

Fan Speed Power Hourly Running Cost Annual Running Cost
1 (Low) 4.5 Watts 0.13c $1.90
2 (Medium) 18.6 Watts 0.53c $7.79
3 (High) 45 Watts 1.29c $18.86

As you can see in the table above, the cost of electricity for a single bathroom fan is less expensive. However, the cost might increase depending on the type of fan you’re using, how long you’re operating the unit, and the additional features available in the fan.

Which is the best to consider?

After this short explanation of how bathroom fans consume electricity, I believe that you’re now fully informed on which quality to consider. Bathroom fans vary depending on the size of the motor and the speed settings. They come in different capacities and wattage ranging from 10W to 100W. For those powerful fans (let’s say 60W to 100W units), the cost of operating such a bathroom fan may cost as much as 2.87c/h which converts to about $42 per year.

Finally, for those who don’t know how to calculate the amount of power used by a single bathroom fan, this mathematical explanation will show you how to do it. 1 Kilowatt-hour (kWh) = 1000 watts. In case a fan has a 20 watts rating, the amount of electricity consumed by this fan is (20÷1000=0.02) meaning it consumes 0.02 units at its maximum speed.

Having explained all that, I will conclude this post by recommending bathroom fans to all homeowners due to their affordability and low electricity usage. Although bathroom fans are inexpensive to operate, some models may be more expensive than others due to the available features and the speed of operation.

Where Do Bathroom Fans Vent To

Where Do Bathroom Fans Vent To

Where do bathroom fans vent to? This is one of the burning questions asked by most people with a high interest in bath fans. To begin with, let me admit that bathrooms are damp places that require regular airflow to keep them fresh and free from odors and smells. As you all know, a bathroom is a damp room that mostly stays in a moist, warm, and wet state due to regular bathing. To ensure that mold and dampness are controlled at all times, a bath fan must be installed to maintain the overall freshness and comfort at all times.

Why consider a bath fan?

There are many reasons why homeowners consider installing bath fans over other ventilating units. Apart from the obvious reason of eliminating odors, smells, and steams from the bathroom, these units go further to reduce the concentration of dangerous and hazardous fumes caused by most cleaning agents.

Now, unlike in the past where fans were only limited to ventilating a room, today’s bathroom exhaust fans have gone ahead to incorporate more outstanding features that make them usable in many different ways. For instance, most bathroom fans available in the market provide a more decorative appeal to the room while still providing sufficient lighting to the entire room when bathing.

In addition to that, these bathroom fans are quieter than before, making them perfect for indoor applications. When it comes to the power rating, these fans are designed in a more efficient manner, allowing them to consume less power than their latter counterparts.

Where do bathroom fans vent to?

When installing a bathroom fan, one question you must ask yourself is where the fan will vent to during operation. To achieve an efficient airflow throughout the room, always ensure that the fan vents towards the roof of the house. This is the perfect vent location for each ventilation unit because of the vast air circulation at the top area. However, depending on the design of the bathroom fan, you’ll find that there are different ways through which a technician can install the ventilation unit. Now, in this section, we will highlight the different bath fan options and see how each one of them is installed.

Through the wall

The first bath fan option is the wall-mounted type of fan. This type of fan is usually installed directed towards the wall either in the interior or exterior wall. This type of fan installation is not very common as it’s only applicable to bathrooms with cathedral type ceiling (those without any attic spacing above) or where the ceiling doesn’t have any additional space left due to the large skylights.

In such a situation, you’ll need to vent the exhaust fan through the wall to the outside. Depending on the location of the bath fan, the ductwork may either be short or extensive as you’ll have to pay attention to every detail to avoid any leakage in the future.

Sometimes you may consider the ductwork to go through the exterior wall. In such a case, you only need to vent the fan directly from the bathroom to the outside wall. This technique is simple and doesn’t require you to do much of the ductwork

Through the roof

This ventilation method is mostly usable in ceiling mounted bath fans. These types of fans are the most common in most bathrooms and they involve installing the fans directly on the ceiling of the room. Such fans are suspended in an upside down position allowing them to remove moisture, odors and steam easily through a suction technique. When air is suctioned from the bathroom, it’s pulled through the ductwork (installed in the attic space) to the roof of the house while still allowing fresh air to get through.

For this method to be accomplished, a hole must be cut on the roof of the house for a vent hood to be installed. This method is very critical and must be accomplished by a professional to ensure that the roof doesn’t leak.

Final thoughts

Having highlighted the various methods of installing a bath fan, I believe that you now understand where bathroom fans vent to. Although these methods are all effective when it comes to ventilating your bathroom, professionals prefer the wall mount method over the ceiling option due to the latter’s ability to keep a house free from leakage incase of rain. With that being said, I believe that you’re now fully informed on how bath fans vent and the different methods of installing the ductwork.

How bathroom fans work

How Bathroom Fans Work

If you are wondering what are those fans are doing in your bathroom, then you have found the right page. It’s time for you to know how bathroom fans work and appreciate their important function in keeping your bathroom well ventilated and your health risk-free.

What are bathroom fans for?

Going back to your first question, bathroom fans aren’t installed to keep you cool while showering or doing your other businesses. It is intended to remove the moisture and humidity that cause foul odors or mold buildup. Because your shower area is a damp place, it is prone to be a breeding ground for bacteria. So, the best way to maintain the air quality and cleanliness of your bathroom is to install ventilation systems like a bathroom or exhaust fan.

Today’s bathroom fans are more than just fans or rotor blades. Now, they are electrically powered with AC or DC motors that ensure consistent operation day in and out. Aside from this, they are quieter and efficient in exhausting humidity and improving airflow. Most manufacturers also make bathroom fans aesthetically pleasing, complementing wall decorations. Some even include a light bulb to add brightness to the room.

Aside from bathrooms, this type of exhaust fan also contributes in maintaining the air quality of the entire house. If all restrooms in your house have bathroom fans, the humid air or smell can be expelled outside the house in no time. Of course, the effectivity depends on how powerful they are.

In summary, here are the purposes of bathroom fans:

  • To remove moisture and humidity
  • To eliminate smelly bathroom odors and air pollutants
  • To prevent water vapor that accumulates on the walls and mirror
  • To improve the overall air quality of the bathroom and home

How bathroom fans work

The simplest way to explain the operation is to know the role of each part. Every bathroom fan has a motor, a fan, and a vent; these are essential parts that need to be present in a unit to guarantee successful ventilation. The motor needs an electric supply to power the fan. As the rotor blades spin, moisture is drawn up and is exhausted through the vent hood. This will continue as long as the bathroom fan is plugged in or turned on.

The effectivity of the fan depends on the power, which is rated in cubic feet per minute or CFM. This is the measurement of the airflow capacity of how much the fan can draw moisture from the room in a specified period of time. Thus, it means that the higher the CFM rating, the more air is exhausted and the faster the airflow is. So, if you have a big room, you should get a bathroom fan with high CFM rating.

Airflow

As a general guideline, one CFM is equivalent to one square foot of the room. For a 100-square-foot bathroom, you should get a 100 CFM exhaust fan. For bathrooms with a standard toilet, bathtub, and shower, an additional 50 CFM is needed to ensure proper ventilation since these fixtures are always damp or wet. For this reason, purchasing a bathroom fan with the right size and specifications is crucial. If the power rating is too low for the size of the room, moisture and odor won’t be effectively eliminated.

Sound

The old-style exhaust fans in the bathrooms are noisy, yet they are not properly doing their jobs. Today, you will find that electrically powered fans are more effective. However, the thing about powerful motors is that they are still noisy. And if they are not noisy, it means that they are not exhausting air at all. That’s why manufacturers integrate such kinds of technology to minimize the sound the motor produce. The noise of a bathroom fan is measured in sones. A good one has an average rating of 1.5 to 2.5 sones. Anything that goes beyond that will be disturbing to the ears.

Installation options

This type of appliance comes in different shape and sizes. They can be mounted on the ceiling, walls, or installed inline. All have their own pros and cons in terms of aesthetic design and performance. Aside from this, some bathroom fans can either have a simple switch for turning on and off, or a timer, exhausting moisture after you take a shower.

What size bathroom fan do i need

What Size Bathroom Fan Do I Need

Nothing beats a refreshing shower in a clean and spa-like bathroom. But do you know the secret of keeping your bathroom free from foul odors and bacteria? Yes, that’s the white grille mounted on the ceiling or wall, which is commonly called a bathroom fan. This electrically powered appliance is an important addition to every bathroom because it is designed to improve airflow and reduce excess humidity. Overall, it helps in making your bathroom a safe place for your family by preventing the accumulation of bacteria or mildew.

You might be asking yourself, “What size bathroom fan do I need?” Fret not. If you are looking to replace your broken bathroom fan and do not know how to find the right one, this article is for you. Here, you will find out how you will know the right size of bathroom fan to choose as well as the other important buying factors to consider.

What Size Bathroom Fan Do I Need?

The most common question that people ask when buying a new unit is what size bathroom fan do I need? That is because bathroom fans come in different shapes and sizes, so choosing has become somehow confusing. Aside from this, it is paramount for you to get the right size of bathroom fan to ensure that your restroom will be well ventilated.

Bathroom fan sizes are based on its airflow capacity that is measured in CFM or cubic feet per minute. The general rule of sizing according to Home Ventilating Institute (HIV) is 1 square foot equals to 1 CFM. For example, your bathroom is 100 square feet, the right bathroom fan for you should, therefore, has 100 CFM. However, you should also take note that having toilet, shower, and other fixtures in the bathroom mean more wet area. So, HIV also recommends adding 50 CFMs for every fixture, especially in public and communal bathrooms.

Installation

Bath fans are mostly seen installed in the ceiling, but you can also find models that are mounted on the wall. Whichever design you prefer, you should remember that the vent part of the fan should exhaust the moisture out of your home. If you have an attic above the bathroom ceiling, then it might not be ideal to mount the bath fan on that part. Another thing to take note is the size of the duct adapter that will be connected to your house’s ductwork. Some models are easy to install by merely following the user manual. However, other models may need professional assistance that can perform complicated wiring procedures.

Added features

Today, manufacturers have added a variety of features to extend the functionality of the bath fans. Aside from fans, they also have light bulbs for extra brightness in the room. This can also replace the fixtures in the bathroom and save energy when needed. Others might integrate night lights and built-in heaters. The most advanced models have sensors that monitor the humidity and motion, turning on the fan when the room reaches a certain humidity level or when there is an action. It will then turn off when the humidity lessens.

Noise level

The loudness of the sound that the bathroom fan produces is measured in sones. If you like taking a rest while enjoying a steamy hot bath, then you would also want a bath fan that operates quietly, lest your peace will be disturbed. 1 sone is equivalent to a quiet sound of the refrigerator while 2 sones are obviously louder and more noticeable than that. There are models that are below 1 sone, producing whisper-silent noise. However, they are more expensive on the market. Bathroom fans producing sounds at 2 sones are ideal and more affordable. But no matter how cheap 5-sone fans are, do not choose them.

Efficiency

Bathroom fans have become more energy efficient today than they were before. The truth is, they are now 70% lower in consuming energy. The performance is still powerful but the consumption is less. It really won’t affect your utility bill when you add a bath fan, so it’s clearly a cost-effective option. What’s more is that bath fans are greener, too. They produce less or no harmful fumes that can potentially harm the environment. To ensure that your unit is cost-efficient, make sure that it is Energy Star certified.
