Understanding Dehumidifiers
Before diving into the factors to consider when choosing a dehumidifier size, let’s take a moment to understand how dehumidifiers work and why you might need one.
How do dehumidifiers work?
Dehumidifiers work by drawing in moist air from the surrounding environment and passing it over a cold coil. As the air cools, the moisture condenses into water droplets, which then collect in a tank or get drained out through a hose. The dehumidified air is then reheated and released back into the room, effectively reducing the humidity level.
Most dehumidifiers are equipped with a fan, which helps to circulate the air and facilitate the dehumidification process. Some models also include additional features, such as air filters to remove allergens and contaminants, or humidistats to monitor and control the humidity level.
Why do you need a dehumidifier?
Excess humidity can lead to a range of problems in your home. High humidity levels can promote the growth of mold, mildew, and dust mites, which can trigger allergies and respiratory issues. It can also cause damage to your furniture, woodwork, and other belongings, as well as create a musty smell that permeates throughout the space.
A dehumidifier can help combat these issues by effectively reducing the moisture level in the air. By maintaining an optimal humidity level, typically between 30% and 50%, you can create a healthier and more comfortable living environment. This is particularly important in areas with high humidity, such as basements, bathrooms, or regions with warm climates.
Furthermore, dehumidifiers can help in preserving the structural integrity of your home. Excessive moisture can lead to rotting of wood, deterioration of paint, and even damage to electrical systems. By investing in a dehumidifier, you can protect your property and save on potential repair costs in the long run.
Factors to Consider
When it comes to choosing the right size dehumidifier, there are several important factors to consider. These factors will help determine the capacity and capabilities of the dehumidifier, ensuring that it effectively meets your needs. Let’s explore these factors in detail.

Humidity level
The first factor to consider is the humidity level in your environment. High humidity levels, above 50% relative humidity, require a larger and more powerful dehumidifier to effectively remove moisture from the air. On the other hand, if your humidity levels are moderate, you may be able to opt for a smaller dehumidifier.
Room size and square footage
The size of the room or area you want to dehumidify is another crucial factor. Dehumidifiers are available in various sizes and capacities, ranging from portable units for small rooms to larger, whole-house models. It’s important to measure the square footage of the space accurately and choose a dehumidifier that can handle the corresponding workload.
Specific area or whole-house dehumidifier
Consider whether you need to dehumidify a specific area or your entire home. If you only need to target a certain room or basement, a portable dehumidifier may suffice. However, if you’re looking to dehumidify multiple spaces or an entire house, a whole-house dehumidifier that integrates with your HVAC system may be a more suitable option.
Desired extraction rate
The extraction rate, typically measured in pints per day, indicates the amount of moisture a dehumidifier can remove from the air within a 24-hour period. This rate varies among models, and the appropriate extraction rate depends on the humidity levels and square footage of your space. Higher extraction rates are generally necessary for areas with high humidity or larger rooms.

Energy efficiency and noise level
Consider the energy efficiency and noise level of the dehumidifier. Look for models with an Energy Star rating to ensure energy efficiency and cost savings. Additionally, if you plan to use the dehumidifier in living spaces or bedrooms, opt for a quieter model to avoid disruption.
Additional features and functionality
Lastly, consider any additional features or functionality that may be important to you. This can include features like automatic shut-off when the tank is full, built-in timers, adjustable fan speeds, or digital controls for easy operation. Assess your specific needs and preferences to choose a dehumidifier that offers the desired features and functionality.
Calculating the Required Size
To accurately determine the size of dehumidifier you need, follow these steps to calculate the appropriate capacity for your space:
Step 1: Measure the room
Measure the square footage of the room or area you want to dehumidify. This will help you determine the appropriate size and capacity of the dehumidifier.

Step 2: Determine the humidity level
Use a hygrometer to measure the current humidity level in the room. Keep in mind that the recommended indoor humidity level is typically between 30% and 50%. If the humidity level is consistently higher, you may need a larger and more powerful dehumidifier.
Step 3: Calculate the required extraction rate
Based on the measured humidity level, you can calculate the required extraction rate, which is typically measured in pints per day. As a general guideline, aim for a dehumidifier that can extract around 10-12 pints of moisture per day for every 500 square feet of space.
Step 4: Consider the room temperature
Take into account the room temperature when selecting a dehumidifier. Some models may not operate optimally in colder temperatures, so be sure to choose one that is suitable for the temperature range of the room you are dehumidifying.
Step 5: Adjust for moisture sources and conditions
Consider any additional moisture sources or specific conditions that may affect the humidity level in your space. For example, if you have a basement that tends to be damp or if there are certain activities that generate more moisture, such as cooking or showering, you may need to adjust the size of the dehumidifier accordingly.
By following these steps and taking into account the specific factors in your space, you can determine the appropriate size and capacity of the dehumidifier that will effectively remove excess moisture and maintain a healthy humidity level.
