Buying Guide
When looking for the best crawl space dehumidifier with pump, there are several factors to consider.
This buying guide will help you make informed decisions based on the features most suitable for your needs.
Capacity
One of the most important aspects to consider is the capacity of the dehumidifier.
This is measured in pints per day (PPD), and it determines the amount of moisture the dehumidifier can remove from the air in a 24-hour period.
Keep in mind the size of your crawl space and the humidity levels so you can choose a dehumidifier with the appropriate capacity.
Built-in Pump
A built-in pump is a valuable feature, as it allows the collected water to be pumped out automatically.
This saves you time and effort by eliminating the need for manual emptying. Opt for a dehumidifier with a pump that can transport water vertically and horizontally, allowing you to drain the water in the most convenient place.
Energy Efficiency
Energy efficiency is essential when choosing a dehumidifier, as it will impact your electricity bills.
Look for a dehumidifier with an Energy Star rating, which means it is designed to consume less energy while still providing excellent humidity control. This not only lowers your energy costs but is also environmentally friendly.
Noise Level
Noise levels are an often overlooked feature but can be crucial for maintaining a comfortable environment.
Dehumidifiers with lower decibel (dB) ratings operate more quietly, so consider this if your crawl space is near living areas in your home. On average, 50 dB or below is considered quiet for a dehumidifier.
User-Friendly Controls
User-friendly controls help make it easy for you to set the desired humidity levels, timer settings, and other functions.
Look for dehumidifiers with intuitive and clear displays, as well as the ability to set your preferred humidity level within a 5% increment.
To make the best purchase decision, carefully consider these factors and choose a crawl space dehumidifier with a pump that meets your requirements and budget.
A dehumidifier with the right combination of features will ensure your crawl space remains comfortable and free from excess moisture.
Frequently Asked Questions
How big of a dehumidifier do I need for a crawl space?
To determine the right size of dehumidifier for your crawl space, you’ll need to consider its square footage and humidity levels. In general, a dehumidifier should be capable of removing moisture from at least the entire square footage of your crawl space. Keep in mind that higher humidity levels may require a larger capacity unit to effectively maintain healthy moisture levels.
What kind of dehumidifier do I need for my crawl space?
The best type of dehumidifier for your crawl space will depend on factors such as your crawl space size, humidity levels, and desired convenience features. A crawl space dehumidifier with a pump is ideal for easy water removal, eliminating the need for manual emptying. Additionally, look for durable models that can handle the challenging conditions of a crawl space and include features such as automatic shut-off, adjustable humidity controls, and energy-efficient operation.
Do I need a special dehumidifier for my crawl space?
While you can use a standard dehumidifier in your crawl space, it’s best to choose one specifically designed for crawl spaces. These models are constructed for harsher environments and typically have more robust components, larger capacity, and added features such as built-in pumps for convenient water removal.
Do dehumidifiers work in crawl spaces?
Yes, dehumidifiers are effective at removing excess moisture from crawl spaces. By maintaining proper humidity levels, they can help prevent issues such as mold, mildew, and structural damage. It’s essential to choose the right size and type of dehumidifier for your crawl space to ensure optimal performance.
What are the top-rated crawl space dehumidifiers with pumps according to consumer reports?
The best crawl space dehumidifiers with pumps will vary based on individual preferences and requirements.

Should I choose a dehumidifier with a drain hose or a built-in pump for my crawl space?
A dehumidifier with a built-in pump offers more convenience and easier water removal than one with a drain hose. A pump allows you to actively push the water out and away from your crawl space instead of relying on gravity for drainage. Additionally, pumps provide more flexibility, as you can route the water further away or even upwards if necessary, without being limited by gravity or the need for a floor drain.
