Best bathroom exhaust fans with light and heater

Heating & Cooling
Eternally damp bathroom on the verge of mold? With a bathroom fan, you won’t let it get that far in the first place.

The best models are not only quiet, but also particularly effective at sucking moisture and unpleasant odors out of the air. This significantly reduces the risk of moldy walls and joints.

What exactly is a bathroom fan?

Visually, bathroom fans look like small ventilators. These are then used to remove odors and moisture from the air. This not only improves the room climate considerably but also counteracts the possible formation of mold. Mold feels particularly at home at a permanent humidity of 60 percent and above. This provides it with sufficient breeding ground to spread quickly. After showering, the humidity can easily reach 80 percent and higher.

Bathroom fans are usually installed on the ventilation shaft of the bathroom and connected to the power supply. When powered, these direct the stale air into the exhaust vent. Here, for the most part, there are two options available. The installation on the ceiling or on the wall.

Even in a bathroom with a window, the installation of a bathroom fan can be worthwhile. Because especially in winter, this allows the windows to remain closed. This keeps the heat in the bathroom and reduces the necessary energy consumption and thus heating costs.

Advantages of a bathroom fan

  • Hardly any space required, as it can be installed on the ceiling or wall.
  • Hardly any space required, as it can be installed on the ceiling or wall.
  • Always fresh air in the bathroom.
  • Can also be used in the kitchen.
  • Helps to avoid mold infestation.

Disadvantages of a bathroom fan

  • Power consumption.
  • Possibly high operating noise, depending on the device used.

How does a bathroom fan work?

Contrary to the assumption that this type of fan would be limited only to the bathroom, they can be used in a variety of ways. Thus, installing the bathroom fan in other rooms with poor ventilation is quite reasonable. For example, the fan can be used in a kitchen or basement room to remove moisture, bind odors and prevent mold growth there as well.

The bathroom fan is available in different variants. In the basic version, switching on and off starts the fan, which draws in air and discharges it through the ventilation shaft. For the most part, the on and off is connected to the light switch for the room. Thus, the operation starts as soon as the light is turned on.

However, in addition to this control, there are also bathroom fans that respond to movement and automatically measure humidity via a hygrometer. Likewise, there are fans with wall controllers, where the user can be adjusted according to personal requirements. However, with the latter, inadequate ventilation is possible with inaccurate settings.

Likewise, the functions of start-up delay and overrun have proven useful. With the start-up delay, the fan only starts to run after a certain time, for example after it has been supplied with power via the light switch. This prevents the fan from starting if something is only quickly fetched from the bathroom.

The after-run ensures optimal ventilation and keeps the room climate and the room scent at an optimum level. This technology also works when the light is already switched off. As a rule, this overrun time can be set manually.

If all this is too much for you, you can remedy the situation with automatic bathroom fans. These continuously measure the humidity and switch on automatically if necessary. A motion detector can also be used to ensure that the ventilation starts when the user enters the bathroom. Thus, modern bathroom fans have all sorts of useful functions that can be combined with each other to achieve an optimal result.

What are the types of bathroom fans?

On the one hand, bathroom fans differ in the way they are mounted. There are built-in fans, which are mounted directly on the shaft intended for ventilation. Thus, the stale or humid air is discharged from the room directly through this shaft. Here there are models that can be mounted on the wall as well as on the ceiling. This depends on where the intended ventilation shaft is located. There are also devices that can be used only on the wall or only on the ceiling.

In the actual mode of operation, that is, the discharge of the room air, these do not differ. Nevertheless, there are criteria that allow a better selection of models. Individual functions, such as overrun, motion sensor, or hygrometer are very practical, but there are other features that should be taken into account.

Features of different models

  • Operation:

Available are manual and automatic bathroom fans, which present themselves with different functions. Which one is suitable depends on the personal requirements. Nevertheless, it can be stated that devices that are supposed to prevent mold infestation should best control themselves automatically and have a hygrometer.

Functions such as the overrun and the start-up delay are features that correspond to individual ideas and wishes. If you want full control, you can get it through bathroom fans with a wall element, on which all functions can be controlled separately.

  • Air circulation:

This value can be used to determine whether the bathroom fan is sufficient for your own room dimensions. It indicates the maximum amount of air that is exchanged per hour.

  • Sound power:

Under certain circumstances, the background noise of a bathroom fan can definitely be perceived as annoying. The sound power of the desired model is specified in decibels. The rule here is that devices below 25 decibels are almost imperceptible. 30 decibels represent the volume of a quiet room or light wind. Above 40 decibels, the sound power corresponds to soft music or whispering.

  • Design:

Not a mandatory criterion in the selection of the appropriate bathroom fan is appearance. Nevertheless, the design should naturally fit seamlessly into the overall appearance of the bathroom. There are usually three different materials to choose from: Plastic, stainless steel, and chrome. Depending on the model, these are still provided with correspondingly beautiful trim.

Other advantages of bathroom fans

  • Prevention of mold:

Especially in the bathroom or kitchen, where there is a lot of moisture in the air, mold likes to grow. This is where it feels particularly comfortable and finds enough food to spread quickly. Especially corners and cracks are affected by the fungus. This can be prevented by effectively reducing the humidity in the room air. Those who have a window in the corresponding room can do this manually by intensive ventilation.

Without a window, the removal of the moist air must be regulated differently. In this case, the fan provides an appropriate balance and leads to a more pleasant room climate. However, the use can also be useful in rooms with windows, especially in the cold months to save heating energy.

  • Versatile use:

However, a bathroom fan can be used not only for the bathroom. It can also be used in basement rooms that have no windows or only a small window. Especially in these rooms, which are usually poorly ventilated, unpleasant room air and mold form. Accordingly, the things stored there are also affected.

Also in the kitchen or in a pantry it quickly becomes humid and the air is enriched, with various odors. Here, too, the fan unfolds its potential and ensures a pleasant room climate without energy being lost through the windows or mold forming.

  • Better room climate:

Not only is the bathroom fan effective against mold caused by moisture in the air, but it also ensures a pleasant room climate at the same time. This way, it becomes neither too humid nor too dry. Likewise, odors are transported out of the room, which is perceived as annoying. Likewise, stuffy rooms are supplied with fresh air due to the air circulation and musty rooms are a thing of the past.

  • Energy consumption of a bathroom fan

Like all electrical appliances, the bathroom fan needs electricity to do its job. However, the energy costs here are relatively low. Nevertheless, manufacturers are always trying to keep the consumption, despite an appealing performance, as low as possible. Thus, many bathroom fans today are divided into well-known energy efficiency classes. Nevertheless, the devices are constantly upgraded with new innovations, which can also have a positive effect on the energy budget. However, the exact consumption can be read in the datasheet of the models.

How to clean a bathroom fan and ensure hygiene?

leaning the bathroom fan is comparatively simple, but should be done regularly. If you want to clean your bathroom fan, climb up to the device with a ladder or a step.

Remove dust as well as dirt from the blades using a soft cloth and conventional cleaning agents. You can reach the bath fan filter, which traps impurities, by removing the bath fan cover.

A thorough cleaning should be done at the latest when the bath fan is humming. Thick layers of dust and dirt can develop unusual noises in combination with the fan. However, after cleaning or replacing the filter, it will be quieter in your bathroom again.

How to choose a suitable bathroom fan and enjoy the benefits?

Various bathroom fan tests have shown that most devices achieve good to very good results. Only in detail, some models collect extra points for additional sensors, a very quiet operation, or particularly favorable prices.

In summary, it can be said that with bathroom fans you enjoy many advantages, which are matched only by small disadvantages:


  • Moisture is reliably removed.
  • The formation of mold is prevented.
  • Bad odors disappear.


  • Electricity consumption increases minimally.
  • The noise is perceived as unpleasant by sensitive people.
  • You need to clean the bathroom fans regularly.

A combination ventilation fan with heat and light delivers immediate warmth when you step out of the shower while quietly clearing the bathroom of excess moisture. Extra-wide heat lamps keep your bathroom warmer with fewer cold spots.

How long does a bathroom fan need until it “works”?

Here, the models differ from each other in their performance. The effectiveness of the device in this regard can be read from the specified circulation rate. With the help of this value, we can read exactly how long a bathroom fan needs to have sufficiently ventilated the room. So, small bathrooms can be vented faster with a lower circulation rate, while for larger bathrooms, special emphasis should be placed on fast air circulation.

Models with automatic are also able to measure the humidity in the room and turn it on automatically if necessary. For example, the fan begins to extract the generated moisture already during the shower. Some devices also have a run-on function, which ensures that the fan continues to run for a certain time after it has been switched off.

Those who are not regularly in the apartment but still value regular ventilation can also consider buying a fan with an integrated timer, which automatically carries out the ventilation process at set times.
