Buying Guide for the Best Whole Basement Dehumidifier

Choosing the right whole-basement dehumidifier is crucial to maintaining a comfortable and healthy environment in your home. A dehumidifier helps to control the humidity levels, preventing mold growth, reducing allergens, and protecting your belongings from moisture damage. When selecting a dehumidifier, it's important to consider several key specifications to ensure you get the best fit for your needs. Here are the main factors to consider and how to navigate them.
CapacityCapacity refers to the amount of moisture a dehumidifier can remove from the air in a 24-hour period, usually measured in pints. This spec is important because it determines how effective the dehumidifier will be in controlling humidity levels in your basement. For small to medium-sized basements, a capacity of 30-50 pints may be sufficient. For larger basements or areas with high humidity, you might need a unit with a capacity of 70 pints or more. To pick the right capacity, consider the size of your basement and the average humidity levels.
Coverage AreaCoverage area indicates the maximum square footage that the dehumidifier can effectively handle. This is important to ensure that the dehumidifier can manage the entire space of your basement. Coverage areas can range from 1,000 to over 4,000 square feet. To choose the right coverage area, measure the square footage of your basement and select a dehumidifier that can cover at least that amount. If your basement is divided into multiple rooms, consider a unit with a higher coverage area or multiple units.
Energy EfficiencyEnergy efficiency is a measure of how much energy the dehumidifier uses to remove moisture from the air. This is important because a more energy-efficient unit will save you money on your electricity bills and is better for the environment. Look for dehumidifiers with an Energy Star rating, which indicates that the unit meets energy efficiency guidelines set by the Environmental Protection Agency. To pick the right one, consider the long-term energy savings and the environmental impact.
Noise LevelNoise level refers to how loud the dehumidifier is when it is operating, usually measured in decibels (dB). This is important if you plan to spend time in the basement or if the noise could disturb other areas of your home. Dehumidifiers can range from very quiet (around 30 dB) to quite loud (over 60 dB). To choose the right noise level, consider where the dehumidifier will be placed and how sensitive you are to noise. If you need a quieter environment, look for units with lower decibel ratings.
Drainage OptionsDrainage options refer to how the dehumidifier disposes of the collected water. This is important for convenience and maintenance. There are typically three options: manual removal, gravity drainage, and pump drainage. Manual removal requires you to empty the water tank regularly. Gravity drainage allows the water to flow out through a hose to a nearby drain. Pump drainage uses a built-in pump to move the water to a higher location or further away. To pick the right option, consider how often you can empty the tank and the location of your basement's drainage system.
HumidistatA humidistat is a built-in device that measures and controls the humidity level in the air. This is important for maintaining a consistent and comfortable humidity level in your basement. A dehumidifier with a humidistat can automatically turn on and off to maintain the desired humidity level, which can save energy and reduce wear on the unit. To choose the right one, look for a dehumidifier with an adjustable humidistat that allows you to set your preferred humidity level.
FilterThe filter in a dehumidifier helps to remove dust, allergens, and other particles from the air. This is important for improving air quality and protecting the dehumidifier's internal components. Some dehumidifiers have washable filters, while others require replacement filters. To pick the right filter, consider any specific air quality concerns you have and how easy it is to clean or replace the filter. If you have allergies or respiratory issues, look for a dehumidifier with a high-efficiency particulate air (HEPA) filter.
