Key buying factors
Choose based on humidity level and room size. For very damp basements, 50+ pints/day is recommended; commercial use may require 100+ pints.
Look for Energy Star Most Efficient designation to save on electricity. Integrated humidistat and auto defrost improve efficiency.
Manufacturer ratings can be optimistic. We recommend sizing up for open floor plans or high ceilings.
Gravity drain hose or built-in pump allows continuous drainage without emptying the bucket. Pump is essential for basements without floor drains.
Compact units can be loud. For living spaces, aim for 45-50 dB. Commercial units are louder but acceptable in basements.
Look for corrosion-resistant coils, washable filters, and at least a 1-year warranty. Commercial models often have longer warranties.
Types explained
Small units (30-50 pints) suitable for bedrooms, offices, or small basements up to 1,500 sq ft. Often lightweight with no pump.
Best for: Small spaces with moderate humidityMid-range units (50-80 pints) for whole-home use or large basements up to 4,000 sq ft. Usually Energy Star certified with hose option.
Best for: Large basements and open-plan areasHigh-output units (90+ pints) built for continuous operation in construction, warehouses, or very damp basements. Features pump and heavy-duty components.
Best for: Severe moisture problems and continuous useCare & usage tips
A clogged filter reduces efficiency and airflow. Washable filters can be rinsed with water; replace if damaged.
Dust on evaporator or condenser coils can impair performance. Use a soft brush or compressed air annually.
Ensure the drain hose is not kinked or clogged. For pump models, check the pump intake and clean the float switch regularly.
We found that the most reliable units combine an Energy Star rating with user-friendly features like pump drainage and washable filters. Higher pint capacity doesn't always mean better efficiency-check the Energy Factor (EF) rating.
For basements, we recommend a unit with a built-in pump and a condensate hose attachment. This eliminates the need to empty the bucket and allows drainage up into a sink or utility drain.
Frequently asked questions
How do I choose the right size dehumidifier?+
We recommend at least 50 pints per day for a 2,000 sq ft damp basement. Use the Energy Star sizing guide: 30 pints for 1,000 sq ft moderately damp, 50 for 2,000 very damp, 70+ for larger or commercial spaces.
Can I run a dehumidifier continuously?+
Yes, most modern units have auto-restart and continuous drainage options. Commercial models are designed for 24/7 operation. High humidity may cause the unit to run constantly until humidity drops.
What does Energy Star Most Efficient mean?+
It means the unit is in the top tier of energy-efficient models for that year. These models use 10-15% less energy than standard Energy Star models.
Do I need a dehumidifier with a pump?+
If your basement has no floor drain or you want to drain upward into a sink, a pump is essential. Pump models also allow remote drainage placement.
How often should I clean the filter?+
Every 30 days of operation. A dirty filter reduces airflow and efficiency. Some models have indicator lights.
