Why You Need a Dehumidifier for Your Crawl Space

The crawl space is usually damp or moist due to water leaks from your ventilation system or water damage due to flooding. It's not surprising it is where mold, mildew, and other contaminants, like bacteria, thrive.

What's more, the moisture build-up can cause warping and rot in wooden support beams, damaged electrical connections, and corrosion in metal appliances, like water heaters and furnaces. It may also lead to insect invasion, water damage to your personal items kept down in storage, and even skin and respiratory irritations.

The real problem is that this kind of moisture doesn't stay out. It works its way upwards through the walls and air, raising humidity and increasing contamination levels in your home.

Installing a crawl space dehumidifier can significantly reduce the amount of moisture in such areas, keeping the humidity levels in check. Plus, it prevents the issues mentioned above from ever occurring.

The AlorAir Commercial Dehumidifier is a great option for anyone looking for a medium-capacity unit to get rid of moisture issues in their crawl spaces. It has a 113 PPD capacity in saturation conditions and 55 PPD in AHAM conditions. This makes it ideal for spaces covering 1,200 square feet.

The unit features a filter to prolong its life, and it's easily accessible from the side of the machine. The dehumidifier also comes with an automatic defrost setting to help protect its coils from freezing and memory restart. In other words, the unit will pick up from where it left off after a power outage.

The unit comes with a 5-year warranty.

The Dri-Eaz PHD 200 Commercial Dehumidifier features a compact design that makes it ideal for drying out your crawl space or basement. It can remove up to 16 gallons of water daily.

The unit comes equipped with touch-pad controls that display inlet and outlet temperatures in real-time. It also features an auto pump-out system that automatically pumps out water to allow for continuous operation. The rugged casing is built to withstand harsh conditions, making it highly durable.

With a capacity of up 150 pints per day in saturation conditions, the Waykar 155 Pints Commercial Dehumidifier is designed to handle the humidity in large spaces. It features an intelligent touch control system that senses room humidity and controls dehumidification to maintain your pre-set moisture levels.

Once the room humidity reaches the set level, it automatically shuts off and restarts again when the humidity goes above. It has a removable air filter that keeps dust from clogging the coil.

It also comes with an auto-defrost function that allows you to use it in environments as low as 41 degrees Fahrenheit. The Power Outage Restart function restarts the unit automatically after a power outage so you don’t have to do it manually.

Aprilaire – 1830Z 1830 Pro Dehumidifier

To prevent the growth of mold due to high moisture levels, you need a powerful crawl space dehumidifier like the Aprilaire 1830z 1830 Pro Dehumidifier. It can remove up to 70 pints (nine gallons) of water daily at AHAM standard levels in spaces covering up to 3,800 square feet.

The unit has a set-it-and-forget function, meaning it will automatically shut off and on, depending on humidity levels. It comes with a dust and particle filter and uses gravity to drain water out.

The 1830Z 1830 model is a low-maintenance unit that's easy to set up. However, it doesn’t come with a built-in pump so you must set it up properly for it to function.

AlorAir Basement/Crawl Space Dehumidifier 120 PPD

If you only have a small crawl space that you want to dehumidify, you don’t need large units. The AloirAir Basement/Crawl Space Dehumidifier 120 PPD covers an area up to 1,300 square feet and has an airflow capacity of 130 cubic feet per minute.

It's capable of removing 55 pints per day at AHAM conditions, and 120 pints at saturation. Like most units, it features an automatic defrost function to help prevent frost build-up and issues associated with it. This keeps the unit running continuously.

It's also equipped with internal corrosion protection to minimize corrosion and freon leakage, extending the life of the coils. The unit is energy star certified, meaning it consumes less energy. Customers get up to 5 years warranty, which tells you it’s a dehumidifier you can rely on.

Dri-Eaz 7000XLi LGR Commercial Dehumidifier

If you have very large areas, the Dri-Eaz 7000XLi LGR Commercial Dehumidifier can cover a whopping 26,000 cubic feet and extract up to 111 liters (235 pints) of water per day. It's heavy, weighing up to 107 pounds (48 kgs), meaning you can't keep moving it around.

The unit comes with a pump and auto-defrost function and is shipped with a draining hose length of 40 feet and a 25-foot power cord. It features built-in sensors that adjust fan speed depending on the conditions. The LCD display makes it easy to control various settings like turning the humidifier on and off.

While the Dri-Eaz 7000XLi LGR dehumidifier is highly effective in drying out damp areas, it can be quite loud, creating a humming sound.

To Consider Before Your Purchase

Crawl space dehumidifiers come in different sizes and each with unique features. Generally, you may want to consider factors like:

  • Water removal capacity. Go for at least 30-pint models. However, your choice will depend on humidity levels.

  • Auto-defrost function, which helps prevent excessive frost from building up and possibly damaging the coils.

  • Ease of use. Usually, dehumidifiers aren’t complicated, but some are easier to use than others. For example, you may want a unit with a well-lit control panel to make it easier to use in a dimly lit crawl space.

  • Size. Keep the weight and size of the dehumidifier in mind in relation to where you’ll be placing it. Remember to take the dimensions of the system to see if it will fit your crawl space.

Very Good Dependable Product

This dehumidifier works almost too well! It’s great for bigger jobs and you can always count on dri-Eaz products to give you dependable professional results! I’ve had it almost a year and it’s working beautifully!” (Michelle Kelleher about dri-Eaz on Amazon) 

Will last about 5 years

I have had two Aprilaire units. A 1730 which kept giving a E4 code and had to be replaced with an 1850 which is now almost 5 years old and is coding an E4. The initial installer is out of business and I had to call another HVAC company but Aprilaire advises this company will have to call their techs and follow a process over the phone before any warranty will be covered. NO more Aprilaire units!” (Goodpm about Aprilaire on Amazon)
