Bathroom Dehumidifier vs Exhaust Fan: A Quick Comparison Guide

Are you struggling with excess moisture in your bathroom and can’t decide between a dehumidifier or an exhaust fan?

You’ve come to the right place!

This article will delve into the differences between the two options and discuss their pros and cons to help you make an informed decision.

1. Role and Function of Bathroom Dehumidifier

Bathroom dehumidifiers are designed to help control the humidity levels in your bathroom by removing excess moisture from the air.

High humidity can lead to problems such as mold, mildew, and damage to fixtures and walls.

Types of Dehumidifiers

There are two main types of dehumidifiers: compressor dehumidifiers and desiccant dehumidifiers.

• Compressor Dehumidifiers use a refrigerant to cool the air, causing the moisture to condense and be collected in a container or drained. These dehumidifiers are more efficient when operating in warm, humid environments like your bathroom.
• Desiccant Dehumidifiers use a special material called a desiccant to absorb moisture from the air. They work well in colder temperatures and are typically quieter than compressor dehumidifiers. However, they may be less energy-efficient.

A third option, a portable dehumidifier, can be a great choice if you only need moisture control during specific times or in specific areas.

Capacities of Dehumidifiers

Dehumidifiers come in various capacities, measured in pints of moisture removed daily.

Keep in mind the size of your bathroom and the severity of the humidity problem when considering these options:

• Small-capacity: removes up to 30 pints of moisture per day. Ideal for small to medium-sized bathrooms and moderate humidity levels.
• Medium-capacity: removes 30 to 50 pints of moisture per day. Suitable for larger bathrooms or higher humidity levels.
• Large-capacity: removes more than 50 pints of moisture per day. Best for very large bathrooms or extreme humidity situations.

Consider the different types and capacities of dehumidifiers to find the best option for your bathroom.

Maintaining a comfortable humidity level will make the bathroom more pleasant and help avoid common problems associated with excess moisture.

2. Role and Function of Exhaust Fan

An exhaust fan is crucial in maintaining proper airflow and air circulation in your bathroom.

Its main function is to draw out moist, stale, and odorous air from the space and replace it with fresh air from the outside.

Doing so effectively reduces humidity levels and prevents the buildup of mold, mildew, and other harmful contaminants, ensuring a healthy and comfortable environment for you.

There are different types of exhaust fans, such as ceiling exhaust fans, which are installed in the bathroom ceiling, and wall-mounted exhaust fans, which are mounted on the bathroom wall.

Depending on the size and layout of your bathroom, you can choose the most suitable type for your needs.

Airflow in exhaust fans is measured in cubic feet per minute (CFM).

The higher the CFM rating, the more air the fan can move in a minute and the more effective it is in removing moisture and odors from the space.

To properly size an exhaust fan for your bathroom, consider the room’s volume and the type and frequency of activities that take place there (e.g., showering, bathing).

A general rule of thumb is to aim for a CFM equal to your bathroom’s square footage multiplied by 1.1.

4. Benefits and Drawbacks Of Exhaust Fan

Pros

• Quick operation: Exhaust fans effectively remove humidity while you’re in the shower or having a bath. Once you’re done, they’re done too.
• Space-saving: Built-in units don’t take up any space in your bathroom, as they sit flush against a wall, ceiling, or window.
• Inexpensive: Exhaust fans are generally cheaper than dehumidifiers, making them a budget-friendly option.
• Fresh air: By pushing out humid air and drawing in fresh air from outside, exhaust fans help maintain good air circulation in your bathroom.

Cons

• Noise: Exhaust fans can be quite noisy, which might be annoying, especially for small bathrooms with poor sound insulation.
• Less effective in high humidity: While exhaust fans can provide immediate relief from humidity, they might be less effective in consistently high-humidity environments.
• Energy consumption: Depending on the exhaust fan model, energy consumption could be a concern, especially if running frequently or for extended periods.
• Installation and maintenance: Installing an exhaust fan might require professional help, and regular maintenance, such as cleaning the vent, is essential to ensure optimal performance.

5. Dealing with Mold and Mildew in a Bathroom

Mold and mildew are common bathroom problems due to the warm and humid environment.

They can cause unpleasant odors, damage surfaces, and even affect your health by triggering allergies.

To effectively deal with mold and mildew in your bathroom, consider the benefits of a bathroom dehumidifier and an exhaust fan.

A bathroom dehumidifier extracts moisture from the air, making it an effective solution for preventing the growth of mold and mildew.

Maintaining a lower humidity level in your bathroom creates a less inviting environment for these allergens.

Plus, a dehumidifier can also help alleviate allergy symptoms by reducing the level of airborne allergens.

On the other hand, an exhaust fan functions by circulating the air inside your bathroom, pushing humid air outside, and drawing in fresh air.

This air circulation helps to reduce moisture levels and discourages the growth of mold and mildew.

6. Maintenance and Cleaning Aspects

When it comes to maintaining and cleaning your bathroom dehumidifier or exhaust fan, there are a few key aspects to consider.

First and foremost, the upkeep of bathroom dehumidifiers usually involves emptying the water collection bucket or tank regularly.

You should also habitually check the air filter, as this plays a crucial role in capturing dust and improving air quality. To clean the filter, simply:

• Turn off and unplug the dehumidifier
• Remove the filter from its compartment
• Vacuum the filter gently to remove dust
• Wash it with mild soapy water, if necessary
• Allow the filter to air dry completely before reassembling the unit

Remember, not all dehumidifier filters are washable. Read your user manual for your specific model’s instructions.

On the other hand, exhaust fans require less hands-on maintenance but involve different cleaning tasks.

You’ll want to ensure the vent is clear of dust and debris by periodically removing the cover and vacuuming the fan blades. To do this:

• Turn off the power to the exhaust fan
• Remove the cover, usually by snapping or unscrewing it
• Using a brush attachment, gently vacuum the fan blades and the vent
• Wipe down the cover with a damp cloth or sponge
• Replace the cover and restore power to the fan

Most exhaust fans also include a removable and washable filter, which needs to be cleaned every 3-6 months.

Follow the same cleaning steps as mentioned for the dehumidifier filter if applicable.
