7 Best Dehumidifier for Crawl Space

The space between your first and ground floor that forms the foundation of your house is called the crawl space. It is often confused with the basement. But contrary to common misconception, a crawl space, unlike a basement, is a small space occupying an area of not more than 1.5 meters. 

However, the size of crawl spaces in warehouses, factories, and other expansive commercial locations can be larger than that. Likewise, just like the name suggests, it has just enough space to crawl (and not stand).

Since they are located in an enclosed space with little to no ventilation, they are most prone to water condensation due to high humidity, leaking pipes, cooking, hot showers, etc.

That is why it is mandatory to purchase the best dehumidifier for crawl space to avoid microbial growth problems and allergic infections.

While people give a lot of attention to dehumidifying their homes, they hardly ever care about removing moisture from crawl spaces. As a result, the water collecting in your crawl space eventually spreads across the whole house and negatively impacts your day-to-day life. 

So, to help you prevent this from happening, we have prepared a concise list of 7 great dehumidifiers meant explicitly for use in all types of crawl spaces and basements.

1. ALORAIR 120 PPD Basement/Crawl Space Dehumidifier 

Irrespective of whether you’re buying a dehumidifier for commercial purposes or only for basic household needs, you must never compromise on innovation and features. 

Similarly, just because you only need to dehumidify your crawl space presently, it doesn’t necessarily mean that you should limit yourself from purchasing a good unit. 

You must always look at the bigger picture while investing your money so that you can use one device to fulfil multiple requirements if the need arises in the future. 

That is why ALORAIR 120 PPD Basement/Crawl Space Dehumidifier is a highly durable product with features suitable for household, office, and commercial needs. 

It comes with a 55-pint dehumidification capacity which can go uphill to 120 pints per day at saturation. Hence, it facilitates quick moisture removal for areas up to 1300 square feet. 

Apart from this, it also contains an auto defrost mode which enables unhindered functioning even at temperatures as low as 36°F (or 2°C). What does auto defrost do? 

Dehumidifiers assist in drying out the air by using heating coils which help to evaporate and absorb moisture quickly. During chilly weather, frost can accumulate on these coils, which ultimately leads to their malfunctioning. 

Dehumidifiers with auto defrost automatically initiate defrosting cycles on sensing frost build-up to increase the device’s durability and offer constant uninterrupted services. 

What else does it have to offer? Firstly, an anti-corrosive innovative body design with a MERV-8 filter. Secondly, remote control for the super fun and hassle-free device monitoring experience. 

Thirdly, C-ETL and Energy Star Certification. And lastly, a 5-year warranty with a lifetime of customer support for immediate guidance during times of confusion regarding the product.

Pros

• Value for money
• Remote control
• Auto defrost
• 5-year warranty
• Low noise level
• Energy star rated product
• C-ETL certification
• Very powerful
• Compact design

It is famous for producing some of the finest quality dehumidifiers for various needs like home use, industrial use, infection prevention, and many more.

But why are we suggesting its use for commercial purposes primarily? The reasons are a 10-meter extended removable controller and an additional 5-meter long humidity sensor wire that comes with it. 

Since industries are usually vast areas covering spaces, it is not practically possible to keep on moving back and forth to change dehumidifier settings. Hence, these unique features make manoeuvrability a child’s play and encourage the device to function the way you want.

Pros

• Value for money
• Remote control

And the last one is energy efficiency and intelligent alerts. When it comes to saving electricity, energy-efficient products make sure to consume the minimum voltage possible to offer low-maintenance moisture removal. Smart alerts at the same time are essential to reminding you about:

• Cleaning the filter
• Turning off the dehumidifier before the water in the tank overflows
• And, giving an overall comprehensive output 

It is for covering all aspects of efficient dehumidification.

That is why we highly recommend the Ivation 4,500 Sq Ft (2.25 Gallon) Energy Star Dehumidifier that comes with all the features mentioned above. Plus, it also has additional features like a 6-foot long power cable (comes with the unit), a built-in RHT Meter, 4 castor wheels adjustable fan speed, and a 24-hour timer.

Things to Consider while buying a crawl space dehumidifier

When looking for the best dehumidifier for crawl space, it is okay to overlook certain factors like the amount and the intensity of noise that it produces while functioning.

For the reason that you want to keep it in your crawl space or basement where you don’t usually reside or do important tasks, it is okay to have some noise because it will hardly reach your living area. 

Nevertheless, there are still certain factors that you must consider before purchasing the best dehumidifier with pump for crawl space. These include:

The accurate coverage area of your crawl space: It is measured in square feet.

Amount of moisture removed by the dehumidifier per day

 It is measured in pints and varies according to the relative humidity around your house, AHAM conditions set by the Association of Home Appliance Manufacturers, temperature, and the general weather conditions like dryness in the air or frequency of rainfall in the region you live. 

Energy Efficiency

Generally, for most crawl spaces, it is vital to carry out continuous dehumidification to avoid the accumulation of water in the air. It is also essential to help you safeguard yourself against the issues that it may bring up in the long run. 

That is why it is always good to go for devices that come with options like automatic humidity sensors and work in an environment-friendly way to bring out the best results. Not to mention, energy star-rated products enable quick dehumidification at much cheaper rates than the traditional ones. 

Defrosting System

Although it is not a necessity, going for dehumidifiers with an automatic defrosting system is always helpful for people living in colder climatic conditions. It is an important feature that increases the longevity of your machine. It helps to eliminate all chances of malfunctioning that may occur because of frost gathering up and destroying the internal components of your device. 

Condensate pump

It is physically impossible for places with high humidity to carry out frequent manual dumping of the water tank. In this situation, automatic continuous drainage is undoubtedly a great option. Still, if you have a powerful condensate pump to carry out the constant drainage, the task becomes a child’s play. 

At the same time, it requires minimal manual effort and practically eliminates the need to constantly monitor your dehumidifier for leakages and helps avoid water overflowing. 

FAQs

Can I put a regular dehumidifier in crawl space?

Even though you “CAN” put a regular dehumidifier in a crawl space, it is never recommended. Since crawl spaces are usually small areas that do not require extensive dehumidification, it is always good to go for cheaper options with higher portability and an average removal capacity. 

Also, regular dehumidifiers meant for homes are a relatively much more expensive investment, mainly if your goal is to only dehumidify a crawl space. So, to make sure you do not end up spending more money than required, look for humidifiers with only the necessary features to save some extra cash. 

Does a sealed crawl space need a dehumidifier?

Of course, sealed crawl spaces definitely need a dehumidifier. In fact, if your crawl space is sealed, it is pretty evident that it does not have enough ventilation, which can not only increase but also maximize the amount of water accumulation from the air. The accumulated water can quickly seep into your main living area and interfere with your normal lifestyle if not managed at the right time. 

When should you run a dehumidifier in a crawl space?

The best time to run a dehumidifier in a crawl space is when the humidity levels inside the area exceed 50% amount. (Pro Tip: You can use a hygrometer to measure the humidity levels in your crawl space)

Should a crawl space dehumidifier run all the time?

The answer to this question varies according to the requirements of a particular place. Likewise, if you constantly have high humidity within the indoor air, you may want to run the dehumidifier continuously all the time. 

Conversely, when you reach your target humidity levels and the air becomes extraordinarily dry, you can turn the device off and let it breathe for some time, after which, of course, you can restart when the need again arises. This will help you save power while also providing accurate results on low-cost maintenance charges. 

Verdict

To sum up, even though you might not consider buying a dehumidifier exclusively for your crawl space, it can turn out to be one of the best investments, particularly for homes with large crawl spaces and highly damp indoor air. 

Moreover, before you realize it, it can become the birthplace of most bacterial growth, unpleasant odours, and floor and wall contamination, which, if spread completely (and it will spread!), is highly destructive for your home. As a solution, all of the above 7 mentioned dehumidifiers can be a good starting point. 

Nevertheless, if you ask us to choose one among these, it will definitely be the ALORAIR 120 PPD Basement/Crawl Space Dehumidifier. 

For the reason that it comes with remote control and is good to use not just in your crawl space but also at your home, office, and other commercial areas. Moreover, its C-ETL certification and an outstanding 5-year warranty are two other features that excite us the most.

Therefore, all in all, you get total value for your money with an all-around performance that beats almost every other dehumidifier that comes at the same price and offers the same capacity. So, it is undoubtedly a winning deal for all kinds of dehumidification requirements.
