If your basement feels damp or musty, a dehumidifier can help. But how do you pick the right size? Choosing the right size dehumidifier is very important. A too small unit may not work well. A too big one may waste energy and money.
Why Do You Need a Dehumidifier in Your Basement?
Basements are often cool and dark. They also tend to have more moisture. This moisture can cause mold, mildew, and bad smells. It can also harm walls, floors, and furniture. A dehumidifier takes extra water from the air. It helps keep your basement dry and healthy.
How Do You Choose the Right Size Dehumidifier?
The size of a dehumidifier depends on many things. The most important is the size of your basement. This means the area in square feet. It also depends on how wet the basement is.
Step 1: Measure Your Basement
First, measure the length and width of your basement. Multiply them to get square feet.
| Length (feet) | Width (feet) | Area (square feet) |
|---|---|---|
| 20 | 30 | 600 |
| 15 | 25 | 375 |
For example, a 20 feet by 30 feet basement has 600 square feet.
Step 2: Check How Damp Your Basement Is
Next, check how wet your basement is. There are three levels:
- Dry: No visible water or moisture.
- Moderately damp: Some moisture or musty smell.
- Very damp or wet: Water on floor, walls, or heavy smell.
Step 3: Find The Dehumidifier Size
Dehumidifier size is shown in pints per day. This means how much water it can remove in 24 hours.
Use this simple table to find the right size:
| Basement Size (sq. ft.) | Dry Basement | Moderately Damp | Very Damp or Wet |
|---|---|---|---|
| Up to 500 | 20 pints | 30 pints | 40 pints |
| 500 to 1,000 | 30 pints | 40 pints | 50 pints |
| 1,000 to 1,500 | 40 pints | 50 pints | 60 pints |
| 1,500 to 2,000 | 50 pints | 60 pints | 70 pints |
Example: If your basement is 600 sq. ft. and damp, get a 40-pint dehumidifier.
Other Factors to Think About
Size and dampness are key. But other things matter too.
Ceiling Height
Most basements have 8-foot ceilings. If yours is higher, more air volume means you need a bigger dehumidifier.
Temperature
Basements can be cool. Some dehumidifiers work better in warm air. Choose one that works well in low temperatures.
Drainage Options
Dehumidifiers collect water in a bucket. Some have hose connections for continuous drainage. This is useful in very damp basements.
Energy Use
Pick a unit that uses less electricity. Look for Energy Star labels. It saves money over time.
Signs You Need a Bigger or Smaller Dehumidifier
After buying a dehumidifier, watch how it works.
- If your basement stays damp, try a bigger unit.
- If it removes water quickly and runs less, the size is good.
- If it runs all the time but doesn’t remove water, it may be too small.
