8 Reasons To Use Bathroom Exhaust Fans

If you’re like most homeowners, you probably don’t give your bathroom exhaust fan much thought — that is, until it stops working. But these devices do more than remove excess moisture and odors from the air. 

Here’s a rundown of 8 main reasons to use bathroom exhaust fans:

1. Bathroom Exhaust Fans Remove Moisture From the Air

One of the most critical functions of a bathroom exhaust fan is to remove moisture from the air. That’s especially important in small, enclosed spaces with little ventilation like bathrooms.

By removing moisture, the fan helps prevent the growth of mold and mildew. That’s important because mold and mildew can cause health problems, such as:

  • Allergic reactions: Some people are allergic to mold and mildew. If you’re exposed to these, you may experience sneezing, coughing, itchy eyes, and breathing difficulties.
  • Asthma: Mold and mildew can trigger asthma attacks in people who suffer from this condition.
  • Respiratory infections: Mold and mildew can also cause respiratory infections, especially in young children and the elderly.
  • Skin irritation: If you have sensitive skin, mold and mildew can irritate it.

2. Exhaust Fans Get Rid of Unpleasant Smells

Nobody likes a smelly bathroom, but unfortunately, it’s not always avoidable. As this study points out, that’s where an exhaust fan comes in handy. By circulating the air and removing odors, the fan keeps your bathroom smelling fresh and clean.

Besides getting rid of bad smells, the fan helps prevent them from spreading to other parts of your home. So, if you have a small bathroom, an exhaust fan can help keep your house smelling pleasant.

3. Exhaust Fans Reduce Humidity Levels in Your Home

Aside from removing odors, bathroom exhaust fans also help reduce humidity levels in your home. That matters because high humidity can cause problems such as:

  • Condensation: When the air is saturated with moisture, it can cause condensation on walls, windows, and other surfaces. In extreme cases, excess condensation can lead to water damage. For example, it can cause paint to peel and wallpaper to warp.
  • Musty odors: High humidity levels can also cause musty odors in your home. If you’ve ever been in a damp basement, you know how unpleasant this can be.
  • Mold and mildew: As I mentioned, mold and mildew thrive in humid environments. By reducing the humidity in your home, you can help prevent the growth of these organisms.

4. Exhaust Fans Protect Walls From Water Damage

Another reason to use a bathroom exhaust fan is to protect your walls from water damage. That’s because high humidity levels can lead to condensation on walls, eventually leading to water damage — which, in turn, causes a number of issues.

For example, if you have drywall, the water can cause the paper to warp and the drywall to crumble. If you have painted walls, the condensation can cause the paint to peel. Either way, you’ll have to repair or replace the damaged wall.

But if you have a bathroom exhaust fan, you can help prevent condensation and water damage. By circulating the air and reducing humidity levels, the fan creates a drier environment less conducive to condensation and its effects.

5. Exhaust Fans Prevent Wood Rot

In addition to protecting your walls from water damage, a bathroom exhaust fan can also help prevent wood rot. That’s because high humidity levels can cause wood to absorb moisture, leading to rot. If the wood in your bathroom isn’t sealed correctly, it can absorb moisture from the air. Over time, that can weaken the wood and make it more susceptible to breakage. 

To prevent wood rot, it’s essential to keep the humidity levels in your bathroom low. An exhaust fan can help you do that by circulating the air and removing moisture.

6. Exhaust Fans Discourage Mold and Mildew Growth

As I mentioned earlier, mold and mildew thrive in humid environments. By using a bathroom exhaust fan, you can help to discourage the growth of these fungi. Mold and mildew can cause several problems, including respiratory infections, skin irritation, and asthma attacks. 

7. Exhaust Fans Regulate Your Bathroom Temperatures

Another benefit of bathroom exhaust fans is that they can help regulate your bathroom temperature. In winter, the fan can help circulate warm air, which can help to heat your bathroom more quickly and efficiently. In summer, the fan can help remove hot air, which can help keep your bathroom cooler. Combined, these can also lower your energy bills.

Common Types of Bathroom Exhaust Fans

Now that you know the benefits of bathroom exhaust fans, you might be wondering what type of fan to buy. There are a few different types of bathroom fans on the market, so it’s essential to choose the right one for your needs.

Here are a few of the most common types of bathroom exhaust fans:

1. Wall-Mounted Fans

Wall-mounted fans are the most common type of bathroom exhaust fan. They’re easy to install and can be placed anywhere in the room.

These fans are available in different sizes and styles, so you can find one that fits your bathroom.

Here are a few things to keep in mind when choosing a wall-mounted fan:

  • Size: Make sure to choose a fan that’s the right size for your bathroom. If the fan is too small, it won’t be effective. If it’s too large, it’ll be too noisy.
  • Style: There are two main styles of wall-mounted fans: axial and centrifugal. Axial fans are more common and have blades that spin in a circle. Centrifugal fans have blades that spin in a spiral.
  • Noise: When choosing a wall-mounted fan, choose one that’s quiet. Some fans are noisier than others, so it’s crucial to find one that won’t be too disruptive.

Here’s a YouTube video that may come in handy when choosing a bathroom exhaust fan:

2. Ceiling-Mounted Fans

Ceiling-mounted fans are another popular option. They’re less obtrusive than wall-mounted fans and can be used in small bathrooms.

These fans are mounted on the ceiling near the center of the room. They’re more expensive than wall-mounted fans, but they offer advantages such as:

  • They’re less likely to be damaged by water or humidity.
  • They don’t take up any floor space.
  • They offer more airflow than wall-mounted fans.

Inline fans are another type of bathroom exhaust fan. These fans are mounted in the ductwork of your home’s ventilation system. Inline fans are more powerful than standard exhaust fans, making them a good choice for larger bathrooms or homes with poor ventilation.

Note: For the best results, inline fans should be installed by a professional.

4. Window Fans

Window fans are an excellent option for small bathrooms or homes with poor ventilation. These fans are mounted on the window and exhaust air out of the bathroom. They are a good choice for small bathrooms because they don’t take up much space and can be easily installed.
