Large Dehumidifier For Basement

Is it better to have one large dehumidifier or two smaller ones?

The decision between using one large dehumidifier or two smaller ones depends on various factors, including the size and layout of the space, the severity of moisture issues, and your specific goals for humidity control. Here are some considerations to help you make a decision:

One Large Dehumidifier:

1. Coverage Area: Large dehumidifiers for basement often have higher moisture removal capacities and can cover larger areas efficiently. If your space is relatively open and uniform, one large unit may be sufficient.

2. Energy Efficiency: In some cases, larger dehumidifiers can be more energy-efficient per pint of water removed compared to running multiple smaller units. This can be advantageous if energy efficiency is a significant consideration.

3. Simplicity: Managing a single dehumidifier is generally simpler in terms of setup, maintenance, and operation. If you prefer a straightforward solution, one large unit might be preferable.

Two Smaller Dehumidifiers:

1. Targeted Moisture Control: Using multiple small dehumidifiers for crawl space allows you to target specific areas with varying humidity levels. This can be beneficial if your space has uneven moisture distribution or if certain areas need more intensive dehumidification.

2. Redundancy: Having two smaller units provides redundancy. If one unit malfunctions or requires maintenance, the other can continue to operate, providing ongoing moisture control. This can be crucial in critical situations.

3. Flexibility: Smaller dehumidifiers offer greater flexibility in terms of placement. You can position them in different areas to address localized moisture issues or concentrate on specific problem areas.

4. Customization: Using two units allows you to customize your approach based on the needs of different sections of the space. This flexibility can be advantageous in complex environments.


- Total Capacity: Assess the combined moisture removal capacity of two smaller dehumidifiers compared to one larger unit. Ensure that the total capacity is sufficient for the size of your space and the severity of moisture issues.

- Energy Efficiency: While larger units may be more energy-efficient per pint of water removed, consider the overall energy consumption of running two smaller units. Modern energy-efficient models can still provide effective dehumidification.

- Cost: Evaluate the cost of purchasing and operating one large dehumidifier versus two smaller units. Factor in potential energy savings and the specific requirements of your space.
