What are the benefits of having a bathroom dehumidifier?

Using a bathroom dehumidifier can offer several benefits. Here are some advantages of using a bathroom dehumidifier:

Mold and mildew prevention

Bathrooms are prone to high humidity due to showers, baths, and sinks. This excess moisture leads to mold and mildew growth, which not only damages surfaces but also poses health risks. By using a bathroom dehumidifier you reduce humidity levels, which makes it harder for mold and mildew to grow.

Odor reduction

Dampness and humidity leads to musty and unpleasant odors in bathrooms. Bathroom dehumidifiers eliminate these odors by reducing the moisture that contributes to them.

Protection of fixtures and surfaces

Moisture can damage fixtures, paint, and wood surfaces in the bathroom over time. By dehumidifying, you prevent warping, peeling, and deterioration of materials, which greatly extends the lifespan of your bathroom features.

Prevention of rust and corrosion

Most bathrooms have metal fixtures and fittings that are susceptible to rust and corrosion due to high humidity. A dehumidifier helps reduce the moisture that accelerates these processes.

Faster drying time

A dehumidifier in the bathroom helps towels and other items dry a lot faster in the bathroom, thus reducing the chances of them developing musty odors or mold.

Extended lifespan of paint and wallpaper

High humidity will eventually cause paint to peel and wallpaper to lift. By maintaining optimal humidity levels, you can help protect these decorative elements.

Bathroom dehumidifier vs. exhaust fan

Choosing between a dehumidifier and an exhaust fan is not always easy because both have their pros and cons.

Most dehumidifiers are large and often bulky, which means they take up more floor space. Now, this may or may not be a problem, depending on the size of your bathroom. But then again, many systems today are much more compact than before without compromising on power, while others can even be wall-mounted.

An exhaust fan, on the other hand, is smaller and installed into walls and ceilings, so they are always out of the way. The only problem is that these fans do not dehumidify. It instead expels a lot of the hot moist air from the bathroom. While this does help a lot in lowering the chances of mold growth, it still doesn’t compare to a dehumidifier that sucks hot air, blows it over cold coils, and then expels dry air. You can also control the exact humidity level you want, thereby making it a lot harder for mold to grow in your bathroom.

Another thing to take into account is that exhaust fans tend to get clogged up every so often, so they do require more maintenance than a dehumidifier.

Small Bathrooms (Up to 100 square feet): For small bathrooms with minimal moisture issues, a dehumidifier with a capacity of around 30-40 pints per day should be sufficient.

Medium Bathrooms (100 to 200 square feet): If your bathroom is medium-sized and experiences moderate humidity, consider a dehumidifier with a capacity of 40-50 pints per day.

Large Bathrooms (Over 200 square feet): Larger bathrooms or bathrooms with significant moisture issues might require a dehumidifier with a capacity of 50-70 pints per day.

Can I use a regular dehumidifier in my bathroom?

Yes, you can use a regular dehumidifier in the bathroom, but it’s recommended to use one designed specifically for bathrooms. Bathroom dehumidifiers are often more compact, have specialized features for damp environments, and are designed to handle the unique challenges of bathroom humidity.

How often should I run the bathroom dehumidifier?

The frequency of usage depends on your bathroom’s humidity levels and how often it’s used for showers and baths. Ideally, you should run the dehumidifier whenever the humidity exceeds 50-60%. Some models have humidity sensors that can automatically adjust the operation based on the current humidity level.

Where should I place the dehumidifier in the bathroom?

Place the dehumidifier in a central location where it can effectively draw in humid air from around the bathroom. Keep it away from walls and obstacles to ensure proper airflow.

Can a bathroom dehumidifier help with mold prevention?

Yes, a bathroom dehumidifier can help prevent mold growth by reducing the moisture that mold needs to thrive. It’s particularly effective in combination with proper ventilation and regular cleaning.

The energy consumption of a dehumidifier depends on its size, capacity, and usage. Energy-efficient models are available, and some have features like auto-shutoff when the desired humidity level is reached.


In conclusion, a bathroom dehumidifier is a valuable investment that can significantly enhance your bathroom’s comfort, hygiene, and longevity.
