#1 Dehumidifier Size Calculator

Sizing your dehumidifier accurately is vital for maintaining indoor comfort and health.

Our Dehumidifier Size Calculator helps you find the right capacity, ensuring efficient moisture control and improved air quality in your space.

Dehumidifiers play a crucial role in maintaining a comfortable and healthy indoor environment.

Choosing the right dehumidifier size is essential for effective moisture control and improved indoor air quality.

In this guide, we'll walk you through the process of calculating the minimum dehumidifier size needed for your space.

Understanding Dehumidification

Before we dive into the calculation, let's understand the basics of how dehumidifiers work and why proper sizing is crucial.

Dehumidifiers help remove excess moisture from the air, preventing issues like mold growth, musty odors, and deterioration of materials.

Choosing the correct size ensures that the dehumidifier can efficiently handle the moisture load in your specific area.

Minimum Dehumidifier Size Calculation

Follow these steps to calculate the minimum dehumidifier size needed for your space:

1. Calculate Area: Measure the area in square feet (sq ft) that you want to dehumidify.
2. Determine Current Humidity: Measure the current humidity level in your space, usually expressed as a percentage (%).
3. Specify Desired Humidity: Decide on the desired humidity level you want to achieve. This is also typically expressed as a percentage (%).
4. Consider Temperature and Air Change Rate: Take note of the temperature in Celsius (°C) and the number of air changes per hour (times/hour) in your space. These factors affect how much moisture needs to be removed.
5. Calculate Required Dehumidifier Capacity: Plug in the values into our calculator, and it will provide you with the minimum pint capacity or liters per day that your dehumidifier should have to effectively maintain your desired humidity level.

How to use Our Dehumidifier Size Calculator

• Area: Enter the area of the space you want to dehumidify in square feet (sq ft).
• Current Humidity: Input the current humidity level in percentage (%).
• Desired Humidity: Specify the desired humidity level you wish to achieve.
• Temperature: Enter the temperature in Celsius (°C).
• Air Change Rate: Input the number of times the air in the space is changed per hour (times/hour).

Once you've entered these values, click the "Calculate" button to get the minimum dehumidifier size needed for your space.

Interpretation of Results

The calculated dehumidifier size represents the minimum capacity required to effectively maintain your desired humidity level. It's recommended to choose a dehumidifier with a slightly higher capacity for optimal performance, especially in cases where the conditions might vary.

Tips for Dehumidifier Maintenance

Here are some tips for dehumidifier maintenance that you should follow:

Clean the filter

The filter is an important part of the dehumidifier that traps dust, dirt, and other particles from the air. A dirty or clogged filter can reduce the airflow and performance of the dehumidifier, as well as increase the energy consumption and noise level. Therefore, you should clean the filter at least once a month or more often if you use the dehumidifier frequently or in a dusty environment. To clean the filter, you can follow these steps:

• Turn off and unplug the dehumidifier.
• Remove the filter from the dehumidifier. The filter is usually located behind a cover or a grille on the front or back of the unit.
• Use a vacuum cleaner to remove any loose dust or debris from the filter.
• Rinse the filter under running water to wash away any remaining dirt. Do not use any soap or detergent, as they may damage the filter.
• Shake off any excess water and let the filter air dry completely before reinstalling it.
• Replace the filter if it is damaged or worn out.

Empty and clean the water tank

The water tank is where the collected moisture from the air is stored. Depending on the size and humidity level of your room or space, you may need to empty and clean the water tank regularly to prevent overflow, leakage, or bacterial growth. Some dehumidifiers have an indicator light or an alarm that tells you when the tank is full and needs to be emptied. Some also have a drain hose connection that allows you to drain the water directly into a sink, a floor drain, or a sump pump. To empty and clean the water tank, you can follow these steps:

• Turn off and unplug the dehumidifier.
• Remove the water tank from the dehumidifier. The water tank is usually located at the bottom or side of the unit.
• Pour out the water from the tank into a sink or a bucket. Be careful not to spill any water on the dehumidifier or on yourself.
• Rinse the tank with clean water to remove any residue or sediment.
• Wipe the tank with a soft cloth or a sponge dipped in a mild solution of water and vinegar. Do not use any harsh chemicals or abrasives, as they may damage the tank.
• Dry the tank thoroughly with a towel or a paper towel before reinstalling it.

Clean the coils and vents

The coils and vents are where the heat exchange and air circulation take place in the dehumidifier. The coils are metal tubes that contain refrigerant that cools down and condenses the moisture from the air. The vents are openings that allow the air to enter and exit the dehumidifier. Over time, dust, dirt, and other debris can accumulate on the coils and vents, which can reduce their efficiency and cause overheating or freezing problems. Therefore, you should clean them at least once a year or more often if you notice any signs of dirt buildup or poor performance. To clean them, you can follow these steps:

• Turn off and unplug the dehumidifier.
• Remove any covers or grilles that protect the coils and vents. You may need a screwdriver or a wrench to do this.
• Use a vacuum cleaner with a brush attachment to gently remove any dust or dirt from the coils and vents. Be careful not to bend or damage any parts of them.
• Use a soft cloth or a cotton swab dipped in water or rubbing alcohol to wipe away any stubborn stains or spots from them.
• Let them dry completely before replacing any covers or grilles.

Store it properly

If you do not need to use your dehumidifier for a long period of time, such as during winter or when you are away from home, you should store it properly to prevent any damage or malfunction. To store it properly, you can follow these steps:

• Turn off and unplug the dehumidifier.
• Empty and clean the water tank as described above.
• Run the dehumidifier for an hour on high setting to dry out any remaining moisture inside it.
• Clean the filter, coils, and vents as described above.
• Wrap up the power cord neatly and securely around the unit.
• Cover the dehumidifier with a plastic bag or a cloth to protect it from dust and moisture.
• Store it in a cool, dry, and well-ventilated place away from direct sunlight, heat sources, or water sources.
