The Best Dehumidifiers

Dehumidifier Types

Dehumidifiers come in various types, each suited for different needs. Compact or portable units are ideal for small spaces like bathrooms or closets, offering targeted moisture removal. Larger, whole-room dehumidifiers are more powerful and suitable for basements, living areas, or multiple rooms. Desiccant dehumidifiers are effective in colder temperatures, while refrigerant models work best in warmer, humid conditions.

Capacity and Coverage Area

Dehumidifier capacity is measured in pints of water removed per day. The size of the area you need to dehumidify will determine the necessary capacity. For moderately damp rooms up to 1,500 square feet, a 20-30 pint model might suffice. Larger, very damp spaces, such as basements up to 2,500 square feet, may require a 50-70 pint capacity unit. Always consider the manufacturer's recommendations for room size coverage.

Features to Consider

Look for features that enhance convenience and efficiency. Adjustable humidistats allow you to set and maintain your desired humidity level. Automatic shut-off features prevent overflow when the water tank is full, and some models offer continuous drainage options via a hose. Energy efficiency ratings are also important to consider for long-term cost savings. Other helpful features include multiple fan speeds, timers, and air filters to improve air quality.

Maintenance and Noise Levels

Regular maintenance is key to keeping your dehumidifier running efficiently. This includes emptying the water tank (if not using continuous drainage) and cleaning the air filter periodically. Different models have varying noise levels, often measured in decibels (dB). If the unit will be used in a living area or bedroom, consider a quieter model, typically below 50 dB.
