Compare Dehumidifiers for Small Apartments

The EPA recommends 30-50% relative humidity for comfort and mold prevention. Most people find 40-45% ideal—dry enough to feel comfortable and prevent mold, but not so dry that skin and sinuses get irritated. In summer, aim for the lower end; in winter, 45-50% may feel better. All our recommended units let you set a target humidity and run until it's reached.

Yes. Energy Star certified dehumidifiers use 15-25% less energy than non-certified models. For a unit running 8-12 hours daily, that can save $20-50 per year depending on your electricity rates. All our full-size recommendations (35+ pint) are Energy Star certified. The savings add up over the appliance's lifespan and reduce your carbon footprint.

Yes, but it's usually unnecessary. Most units have a humidistat—set your target (e.g., 45%) and they'll cycle on when humidity rises and off when it's reached. Running 24/7 in moderate conditions may over-dry the air. In very humid climates or damp basements, continuous operation is fine. Use the continuous drain option for 24/7 use to avoid constant tank emptying.
