Customer Service


Normally, when people come to me and ask whether they should install a dehumidifier in their crawl space, I usually answer with a resound yes, especially for people who live in humid areas. Excess humidity, dampness, and odor affect the health and comfort of everyone in your home. It also has negative impacts on the structural integrity of the property.

The Aprilaire E70 Pro 70 Pint Dehumidifier is a good example of a unit you can install in a crawl space. It has a decent price, comes from a reputable brand, and removes up to 70 pints of water per day. That should be about 40 liters removed from your indoor space in 24 hours.

We did our research on this unit to find out what it brings to any space. And in this article, we will try to answer all the questions you might have about this product. We’ll also highlight some of the cons of this unit to fully help you determine whether it’s the right buying choice for you or not.


Aprilaire has been manufacturing some of the best humidifiers and dehumidifiers in the market since 1954. They focus on providing whole house air ventilation equipment for spaces ranging from 2000 sq. ft. to 6000 sq. ft. You can depend on their products for improving the quality of air in your home and protecting its structure. They also consume less energy during operation. All their products are easy to install and can last for many years.

The company also manufactures air purifiers, thermostats, ventilation solutions, filters, and different accessories for these products. Upon purchasing any of their product, you will get a five-year warranty, a user manual specifically for the model you buy, and continuous support from their customer care team.

I looked at different customer reviews on Amazon on their products, and I couldn’t find anyone complaining about delayed responses from their support team.

Product Features

The Aprilaire E70 Pro 70 Pint Dehumidifier is an updated version of the brand’s 1820 model. It comes with updated features, making it a better option for dehumidifying the air in your crawl space than its predecessor.

Let’s start with the design

Right out of the box, you will find a compact device with a grey body. It weighs 56 pounds and is 12.5 inches long, 12.5 inches wide, and 25 inches high. Hence, it should fit into sealed crawl spaces perfectly. The unit also has four leveling rubber feet that protect the body from scratches.

The dehumidifier also has one inlet and outlet located on both ends of the unit. On the side of the inlet, you will find the MERV 8 washable filter and an electronic control panel with an onboard humidistat. The unit also has a one-speed fan and aluminum coils (which are resistant to corrosion). We also found out that the refrigerant used in this unit is R410A. It’s a highly recommend refrigerant because it is very energy efficient.

Setting up the unit

Installing the dehumidifier in any crawl space is a breeze. You can connect it to your home’s duct work or use it as a freestanding unit. The provided 10 ft. drain hose will drain the water in a nearby sink or floor drain when operating by itself. Once you connect the 8 ft. power cord to a nearby power socket, press the power button to turn it on. It only requires a voltage range of 100 -120V to work.

You can then set your preferred humidity level (between 40% and 80%) on the digital control. The fan will run continuously to sample the air and only dehumidify it when required. Note that you can set the fan to run in continuous mode or only when dehumidifying.

The unit also has an auto restart feature, which will restore your settings in case of a power outage or an unexpected shutdown.


First, let’s talk about the efficiency of the Aprilaire E70 Pro 70 Pint Dehumidifier. The manufacturer recommends this unit for tight crawl spaces, joists, and basements because of its size. It can remove up to 70 pints of water from the air in a day in spaces of up to 2800 sq. ft. That’s about 40 liters of water in a day. If you don’t know how large the space you want to dehumidify is, measure it first. If it’s bigger than the size recommended by the manufacturer and it has more humidity, we suggest you go for one with a higher pint value. You can use this guide to help if you don’t know where to start.

Note that the unit has an airflow capacity of 200 cubic feet per minute. Therefore, it won’t be long before you start seeing the humidity levels in the room dropping.

The unit has an Energy Star Certification. You know very well that units with this sticker don’t consume much energy. It also won’t consume much power since it requires 120V to operate.  We loved the auto restart function since it saves you the trouble of resetting it every time there’s a power outage.

I also took the time to understand how to install the unit. The instructions written in the user manual are easy to follow. In my opinion, you shouldn’t have any issues installing the dehumidifier, even though Aprilaire recommends users to hire a professional to do it.

The other benefit I should not forget to state is it’s not noisy. Once the unit is in your crawl space, you may never hear the fan vibrations since its noise level is 53dB. That’s relatively low. Refrigerators are louder than this, yet they don’t distract anyone in their sleep. Which is yet another reason the dehumidifier is perfect for different crawl spaces in your home.

Also, even though the unit has an inbuilt humidistat, you can still connect it to a compatible wall humidistat for remote monitoring. The dehumidifier also doesn’t use condensate pumps, but you can connect to external ones if you prefer to drain the collected water using them.


Despite the efficiency of the Aprilaire E70 Pro 70 Pint Dehumidifier, what are some of the challenges you should expect to face once you buy this unit? Well, for me, I couldn’t find many. But one thing I can say about the machine is that it would be ideal for dehumidifying one room at a time, especially when there is high humidity.

The unit also lacks smart features. Nowadays, smart products are crucial and this might be a huge disadvantage for you if you’d love to monitor how the unit operates even when you are away from home.


That’s all for today, folks. I hope you have all the information you need to know about the Aprilaire E70 Pro 70 Pint Dehumidifier. We would like to recommend it to homeowners looking for efficient dehumidifiers for their crawl spaces, basements, and other parts of their homes. The unit will supply dry air into your home and prevent mold from growing on the furniture again. You can also use it as a freestanding or a duct to your central duct work.

Once you buy this product, you can be sure that the manufacturer provides a five-year warranty and reliable support on issues regarding the system. You can check their website to see what they say about this. Finally, this unit will also save energy in your home, more reason why you should buy it.
