Excess humidity can damage your home in places like your cellar, where warm, moist conditions can result in mold and mildew, not to mention the musty odor generated that can find its way into your home.

Buying Guide

So, why are we recommending this particular model? The Aprilaire 1830Z Pro Dehumidifier is flexible and just perfect for our needs as it relates to cellars and crawl spaces. This unit is designed to absorb roughly nine gallons or 70 pints of water per day. That’s a lot of moisture that could do a lot of damage to your walls, wood work, not to mention clothing or other fabric items stored down there.

The Aprilaire 1830Z 1830 Pro Dehumidifier has been designed for convenience and low maintenance, perfect for small homes, condominiums, townhouses, cellars, small rooms, and crawl spaces. There is no tray to empty, no parts to clean. The unit is capable of self-diagnosis, so all you are left to do is to replace the filter once a year. And for convenience, the control panel can easily be moved from the top of the machine to the front. As with all models, this unit is built with corrosive-free coils to prevent rusting.

Features To Look For

Ease of Installation

Each unit comes with two duct collars: an inlet collar and outlet, or discharge collar with a built-in backflow damper, and a parts bag with screws, Torx bit, and drain plug, along with an easy-to-follow instruction guide. The discharge collar with the backflow damper can be mounted on the side or on top of the unit, depending on where you want the discharge to be directed. The inlet collar, which goes on the front, is a breeze to screw in.

Then you decided where you want the control panel to go. The control panel comes assembled on top of the unit for convenience as many choose to set it low or place it on the ground. With the controls on top, they are in easy reach when you have to stoop over. Otherwise, you can easily move the control panel to the side for easy reach if the unit sits higher.

After all the parts are connected, place the dehumidifier where you want it, using a level to ensure the unit sits squarely on the surface so the drain is correctly aligned and water can flow into a drain or pipe. All units come with preinstalled leveling feet that can be turned to get it to the proper level.

Next, screw in the drain plug, which is needed to connect to a drain hose or pipe that leads to a drain or condensate pump.

Finally, you plug it in and put the unit through a self-check. If there’s a problem, the company includes a list of error codes you may see and a toll-free number you can use to call for help. Once the self-check is completed, all you have to do is to set the level of relative humidity you want, and it’s ready to go.

Once operational, this unit will remove unwanted moisture that can contribute to mold and mildew that could otherwise build up and cause damage to your home.

This unit is capable of self-diagnosis and so can monitor itself should an issue arise. What’s more, for those using a condensate pump with the unit, it will automatically stop if that pump malfunctions preventing water from spilling out.


What’s the difference between a humidifier and dehumidifier?

While a humidifier adds moisture to dry air to relieve dryness and help ease the dryness of the skin, throat, or nose, a dehumidifier does the exact opposite, pulling excess moisture from the air in confined spaces like your basement to combat mold and dust mites.

What size dehumidifier do I need?

That all depends on the size of your home or the space you want to control. This unit is designed for a home or space up to 3,800 square feet (353 square meters).

Where should I put a dehumidifier?

Wherever you need it. Common areas include the cellar, crawl space, laundry room, and bedrooms. Some are used in indoor pools.

Do dehumidifiers clean the air?

No. Dehumidifiers are built for one specific purpose, to pull excess moisture from the air. On the other hand, they do provide an indirect benefit by helping to control mold and mildew from growing due to excessive moisture.

When should I turn my dehumidifier off?

You should think about turning your unit off when the seasons change, and it gets cool, and the humidity level drops, preventing unnecessary use while saving on the wear and tear of the unit.


If you are looking for a quality product made in the USA to keep your home free from excess moisture, the Aprilaire 1830Z Pro 70 Pint is the unit for you. The unit is easy to install, easy to control, easy to maintain, quiet, energy-efficient, and backed by a warranty and a trained customer service staff ready to help you have problems.
