Choosing the Right Size Dehumidifier

Choosing a dehumidifier is not as simple as just which brand or for how much.  The appropriate size is a vital key to getting exactly what you need for your space and condition.  Here’s a quick list which can help you decide the appropriate sized dehumidifier you may need for your home or business.

Slightly Damp

  • Space which is damp and has an occasional musty smell. 50 to 60 Percent Humidity.
  • 300 Square Feet:  30 Pints
  • 500 Square Feet:  40 Pints
  • 1000 Square Feet:  60 Pints
  • 1500 Square Feet:  70 Pints

Moderately Damp

  • Space often feels damp and often smells musty.  60 to 70 Percent Humidity.
  • 300 Square Feet:  30 Pints
  • 500 Square Feet:  40-45 Pints
  • 1000 Square Feet:  60 Pints
  • 1500 Square Feet:  70 Pints

Very Damp

  • Space feels wet, smells musty and damp spots are on walls and floor.  70 to 85 Percent Humidity.
  • 300 Square Feet:  40 Pints
  • 500 Square Feet:  50 Pints
  • 1000 Square Feet:  70 Pints
  • 1500 Square Feet:  90 Pints

Wet

  • Space feels wet, smells musty, seepage appears on walls and floor & may have mold.  85 to 100 Percent Humidity.
  • 300 Square Feet:  40 Pints
  • 500 Square Feet:  50 Pints
  • 1000 Square Feet:  70 Pints
  • 1500 Square Feet:  100+ Pints

The pint recommendations above are based on manufacturer-stated capacities in varying testing conditions. If you will be using your dehumidifier in a tough environment with very damp conditions, look for a dehumidifier with your recommended pint capacity tested at AHAM conditions (average humidity conditions of 60%) instead of saturation (100% humidity)​.  A model able to remove 70 pints of water when the air is saturated, for example, is much less robust than a model able to remove 70 pints of water at AHAM conditions.

Other Considerations:

If any of the below factors are true for you, you’ll want to choose a unit with a higher capacity.

  • If your home is located in a humid climate, add 10 pints.
  • If multiple people live or will spend time in the space, add 5 pints.
  • If there are multiple doors and windows in the space, add 5 pints.
  • If there’s a washer and dryer nearby, add 5 pints.
