Buying Guide for the Best Dehumidifier
Choosing the right dehumidifier can make your home more comfortable by reducing excess moisture, preventing mold growth, and improving air quality. The best dehumidifier for you depends on the size of the area you need to dry, how damp the environment is, and where you plan to use the device. Focusing on the main features can help you easily compare options and select a model that fits your space and lifestyle.Capacity (Pints per Day)Capacity refers to the amount of moisture a dehumidifier can remove from the air in one day, usually measured in pints per day. This is a crucial spec because it tells you how powerful and effective the device will be for your environment. Lower capacity (20-30 pints) units are ideal for small rooms or mildly damp spaces, while medium capacity (30-50 pints) works for larger rooms or moderately damp basements, and higher capacity (50+ pints) is best for very damp or large areas. To pick the right one, assess the size of the area and how wet it tends to get—bigger, wetter spaces need higher capacity.
Room Size CoverageRoom size coverage tells you the maximum area (in square feet or meters) a dehumidifier can effectively handle. Smaller units are fine for bathrooms or small bedrooms, while open basements or large living areas need a larger unit. Make sure your chosen dehumidifier is rated for the size of space you want to use it in—if unsure, it’s better to go slightly bigger to ensure effective moisture removal.
Drainage OptionsDrainage options determine how the collected water is managed. Most dehumidifiers have a removable tank that you empty manually, but some offer a continuous drain option with a hose attachment, and others can be set up with a built-in pump. If emptying the tank frequently will be inconvenient (like in a very damp room or basement), look for automatic drainage features.
Automatic HumidistatAn automatic humidistat allows the dehumidifier to monitor and maintain your desired humidity level by turning itself on and off as needed. This is important for both energy efficiency and comfort. Look for a model with an adjustable humidistat if you want to set a precise humidity level for health or preservation reasons, such as protecting musical instruments or preventing musty smells.
Noise LevelNoise level is how loud the dehumidifier will be when running, typically measured in decibels. This matters most if the device will be used in a living space or bedroom. Lower noise ratings are better for bedrooms or nurseries, while a noisier unit might be fine for a basement. Consider your sensitivity to noise and where you’ll use the device.
Filter Type and MaintenanceDehumidifiers often have filters to capture dust and allergens. The type and ease of cleaning these filters affect air quality and maintenance. Washable and reusable filters are convenient and save money, but you’ll need to remember to clean them regularly. People with allergies or those wanting cleaner indoor air should pay closer attention to filter features.
Energy EfficiencyEnergy efficiency refers to how much electricity the unit uses in relation to the amount of moisture removed. Energy-efficient dehumidifiers use less power for the same moisture removal, which can save on energy bills and help the environment. Check for energy-saving features or certifications if you plan to run your dehumidifier frequently or for long periods.
PortabilityPortability is about how easy it is to move the dehumidifier from one place to another. This is influenced by weight, handle design, and the presence of wheels. If you might need to use the dehumidifier in more than one room or move it for storage, look for models that are lighter and feature sturdy handles or caster wheels.
