Bathroom exhaust fans are an essential accessory for your bathroom. While other equipment, except the classic tub and sink combo, might be classified as optional, an exhaust fan is certainly something worth investing in. Its main job is to promote air circulation in one of the most humid areas in your house – the bathroom. As you probably know, the bathroom is very prone to humidity-related problems, such as mold formation, lime scale, mildew and other unpleasant smells, paint and even wall cracking. All of these can lead to more or less serious health hazards. Inhaling mold spores can lead to respiratory problems such as asthma, while those always damp towels might be the source of many skin, scalp and hair conditions. Besides those, even the construction of your bathroom can be affected without proper ventilation. If you don’t have tiles all over the walls, the paint or even the wall itself may start cracking, and flaking off if exposed to constant moisture. Marks will also start forming, especially on the ceiling, ruining the aspect of the room. Mirrors will also grow foggy over a very short time, demanding constant changing. The hardware will also be affected if it’s not made out of stainless steel, as it will be prone to corrosion and tarnish. These being said, it’s compulsory that you invest in an exhaust fan if you don’t already have one. But first, let’s take a look at what a bathroom exhaust fan really is.
These being said, it’s pretty compulsory that you get your own exhaust fan if you don’t already have one. To help you out a bit, we’ve put together a top-6 of the best bathroom fans on the market, which should help you find the perfect one for your household.

220V 16W 5 Inch Exhaust Fan Bathroom Ventilation Fan
The 220V 16W 5 Inch Exhaust Fan Bathroom Ventilation Fan is probably the greatest choice for apartments, or for those who prefer to have a horizontal drain pipe, as its duct is also oriented horizontally.
This unit is pretty small, measuring 5 x 5inches, and has an 3-inch duct opening. The power output of this unit is only 70 CFM. Despite its size, this exhaust fan will work for small to medium bathrooms only, as it will have quite a bit of trouble ventilating a room bigger than 15 square meters.
In terms of quality, you will enjoy time-tested quality, which means a galvanized steel corpus and parts, a silent motor that runs at less than 1.1 sones, and an exterior hood with a back-draft damper, which will prevent cold air from getting into your bathroom. The blower wheel on it is designed to draw air into both sides, allowing more air to enter the unit. This makes up for the rather low CFM index, yet does not improve the speed of the process significantly.
As far as aspect goes, this bathroom fan has a very discreet, white grid design, which will keep it from standing out in any bathroom. Besides that, you can get 10% off when you shop this unit using the link below and introducing the code GET10 at checkout:

Exhaust Choosing Guide
A bathroom vent fan is a ventilation system connected to a horizontal or vertical pipe that fans the moisture out of the house. They come in numerous shapes and sizes, but most of them are around 10 x 20 x 10 inches, being the perfect size to mount on the wall without it being too noticeable. The material also differs, but they tend to be made of steel or polymeric, both of which are resistant to moisture damage. The ventilation technology varies from one manufacturer to another as well, and there’s no right or wrong with this one – they all work just as fine. Another feature you should be looking for is the capacity of the unit in relation to the size of your bathroom. Last but not least, bathroom fans can be pretty noisy, so you might want to go for a product that has a quiet motor. Let’s break it down into the main features you should be looking for:
- CFM vs size of the bathroom.
All the products you’ll find online or offline will have the CFM specified. CFM stands for cubic feet per minute, and it equals the amount of air the fan can handle over said period. The size of your bathroom will influence your choice of CFM, as the bigger your room is, the higher the CPM should be. Naturally, if you have an unusually big bathroom, you’re running a business, like a public bath, gym, or whatnot, you might need two or more fans, depending on the size of the space you’re planning to ventilate.
We recommend that you measure your bathroom before going shopping for the perfect exhaust fan. However, if you don’t want to go through the trouble, and you have a pretty standard-sized bathroom, you can go for a fan that runs between 70 and 150 CFM. The time in which it will clean the steam will fluctuate depending on the CFM as well.
This feature can be broken down into two separate categories: the size of the unit itself and the size of the duct diameter. The latter will influence the overall size of the unit, and again, the speed of the ventilation process. Generally, you should look for a unit with a 4 to 8-inch duct, as anything smaller than that would be insufficient to clean up the steam in real time. When it comes to the size of the fan itself, it doesn’t really make much of a difference. The CFM index depends more on the power of the motor rather than on the size of the duct, so a bigger fan will not always equal a better choice. Look for a good balance between motor power (CFM) and size of the duct – but again, you don’t want to go below 4 inches in diameter.
As a matter of fact, the capacity of the fan will not always be specified in CFM. You can also find L/s (liters per second) m3/h (cubic meters per hour). If you stumble upon a product that has any of these different specifications, the minimum you should be looking for is 15L/s and 90 m3/h.
- Energy consumption
Naturally, the first thing we think about when we invest in a new electrical appliance is how much is it going to influence the electricity bill. Luckily enough, bathroom exhaustion fans are not very energy-consuming, and also have a couple of features that will help you save energy in the long run. Some fans come with an indicator light; that will remind you to turn it off in case you forget. As recent models can be absolutely silent, this is a very useful addition, especially if you want to avoid surprises at the end of the month. There are also fans that can run at a specified speed, so you can set it on the lowest setting in case you want to save some energy. This could be a great option if there is an alternative source of fresh air in the room, such as a window. The steam can still linger in the corners, so it would be a good idea to have a fan running on the lowest setting as well.
A rule of thumb to look for is the bigger the fan, the more energy it consumes. Plus, if it has extra features, such as speakers or more powerful lights, that will also make it less energy efficient.
Bathroom exhaustion fans are known for being pretty noisy. While not necessarily producing a loud noise, the continuous humming can give you headaches in the long run, especially if you have to have it on for the whole time you spend in the bath. In any case, it’s better to opt for a unit that has a noise-reduction system, or a quieter motor. However, we would not recommend going for an entirely silent bathroom fan, although they are becoming increasingly available nowadays. The reason for that is that you can’t really be sure whether it’s working properly or not if you don’t hear it at all. Noise can also indicate which part exactly is at fault for a certain shortcoming – thus easing up the fixing process.
Bathroom exhaust fans come in different configurations. If you live in a house and have some kind of attic above your bathroom, you will most likely have to drill the brickwork vertically, letting the steam out through the roof, in a vertical line. However, if your bathroom is not on the top floor of the house, or you live in an apartment, you’ll have to drill a horizontal canal through the wall, which will ventilate the humid air right out of the wall. Respectively, you’ll have to choose between mounting your exhaust fan on the ceiling or on one of the bathroom walls. As far as the exact location of the fan goes, it’s really up to you. Some say it’s better to place it right above your tub or shower cabin, and some say it’s more effective when placed between the toilet and the bathtub or shower. In reality, it all depends on the configuration of your bathroom, and on how you plan to ventilate it. Some prefer turning on the ventilation the moment they get into the shower or bath, so the mirror does not get foggy, and the steam doesn’t even manage to fill up the room. In that case, it’s a good idea to place it as close to the source of the steam as possible, above the bathtub or shower. On the other hand, if you have, say, a steam generator, and you want to enjoy its beneficial effects while you take a bath, it’s indeed recommendable to place it somewhere in the middle of the room. The steam will spread out evenly and will be absorbed much easier through a hole in the center than one in the corner.
The installation of a bathroom exhaust fan is no easy task. You have to have several tools on hand, such as a power drill, screwdriver, a jigsaw, and pliers, as well as some extra materials for isolating, such as caulk, plus a length of duct pipe, and a cap for the vent. If your house doesn’t already have a pre-drilled ventilation hole, you might want to hire a professional to do the drilling for you. The rest can be done by oneself if one has all the necessary tools and knowledge, but the drilling part can be a bit tricky.
As more and more people want to have a perfectly matching set of hardware in their bathroom, even exhaustion fans have started to come in different colors and finishes. You don’t have to worry about a cheap looking fan anymore, as you can now find units in about any color you like. They can also somehow represent the style you’re going for in your bathroom, as you can go for an edgier and modernist appearance, or for a classic, more delicate one.
- Extra features.
Any kind of furniture or equipment for your bathroom will have some extra features you can opt for. As far as exhaustion fans go, you can go for one which has built-in lights. If you’re wondering as to why would you need a fan with lights, manufacturers claim it can solve the problem of poorly lit bathroom corners (if you place it in the corner, that is), but it can also serve as a low-maintenance night light. Kids and elderly people will appreciate that a lot, as you can never be too sure of what’s lurking in the dark when you want to go to the toilet in the middle of the night. However, if you feel like leaving it on for a whole night will bother your sleep, you should go for a silent operation fan. As mentioned before, these are becoming increasingly popular, and those loud, screeching units are left in the past. Besides these, some fans even come with built-in speakers, so you don’t even have to purchase them separately. Grace to these multifunctional devices, you can now keep your devices away from the humidity, while still enjoying your favorite music or radio broadcast.
Bathroom exhaust fans are no expensive products either. You will probably end up spending more on the installation and labor (mainly the drilling) than on the unit itself.
These would be all the features you should look for when shopping for a bathroom exhaust fan. Whether you plan to get a new one to replace your old unit in the bathroom, or you’re just planning to made a brand-new installation, you’ll enjoy a number of benefits, such as:
- Preventing mold formation. Mold can be pretty threatening to one’s health, as well as to the construction of the room – it can cause the paint or wallpaper to come off, and ugly marks to form on the ceiling. With an exhaust fan, the humidity in the room will be reduced to the minimum, keeping away respiratory problems and preserving a nice aspect in the bathroom.
- Preventing mildew or other foul smells. Nothing can be worse than grabbing a towel or a bathrobe that is still damp from yesterday’s bath that has that specific mildew smell to it. Sometimes it can get so bad that you can’t even take it off by laundering the cloth, which leaves you no alternative but to throw them away. A fan will ensure you always have dry and pleasant smelling towels, rugs, bathrobes, and any other textiles you may need in the bathroom.
- Prevents the mirrors from fogging. Mirrors in the bathroom can become foggy very quickly if exposed to humidity. Due to the difference in temperature between the mirror’s surface and the room, condensation forms easily on it, building up a microscopic mineral layer after every bath or shower. These can be very tricky to remove, and normal window cleaner solution will not do the trick anymore. To prevent that, again, a powerful exhaust fan is a great saving solution.
- Prevents the floor from getting slippery. While it might not do much about the water splashes, it can help get rid of the extra steam that will make the tiles on the floor become slippery and unpleasantly wet. No more wet socks in the morning!
We hope this little guide helped you find the perfect bathroom exhaust fan for your house and family. Before purchasing one, don’t forget to take some rough measurements of your bathroom so that you can choose the appropriate CFM rate. Also, don’t forget to look for a proper balance between the duct diameter and the CFM, in order to maximize the efficiency of your product. If you have kids, it’s best to invest in a bathroom fan that comes with a night light function as well. Moreover, if your bathroom is really small, some of these units can provide enough light to illuminate the room by themselves. A silent operation is always a plus with fan, so make sure you go for a unit that runs at less than 1.5 sones. Last but not least, make sure you opt for a product from a reputable company, which offers some kind of warranty, and uses high-quality materials for their bathroom fans. Nothing can be worse than spending money on a bathroom fan, bothering with the drilling and installation and having it break down after a short while.
