Best Dehumidifiers: Expert Reviews for Basement, Crawl Space & Home
Dehumidifiers remove excess moisture from indoor air, maintaining the 30–50% relative humidity range recommended by the EPA for mold prevention, dust mite control, and general comfort. Basement dehumidifiers typically require 50-pint (DOE rating) capacity for spaces up to 1,500 square feet, with a continuous drain option to eliminate manual bucket emptying. Energy Star certification ensures the unit meets EPA efficiency standards. We evaluate units on dehumidification efficiency, noise level, features, and reliability.

Frequently Asked Questions
What humidity level should I maintain to prevent mold?
Keep indoor humidity between 30–50% relative humidity. At 60% and above, conditions become favorable for mold growth. Basements often run above 70% in summer without active dehumidification — well into the zone where mold growth is essentially inevitable over time.
What size dehumidifier do I need for my basement?
For a typical 1,000–1,500 sq ft basement with moderate humidity problems, a 50-pint unit is appropriate. For smaller spaces under 500 sq ft, a 30-pint unit is usually sufficient. In extremely humid conditions (visible moisture, water seeping through walls), step up to the largest unit available and address the moisture source directly.
How do I use the continuous drain feature?
Connect a standard garden hose to the drain port on the back of the dehumidifier. Route the hose to a floor drain, utility sink, or sump pump area. Ensure the hose runs downhill continuously — water flows by gravity, not pressure. This eliminates the need to empty the collection bucket, allowing the unit to run indefinitely unattended.
