Dehumidifier for Basements: 2019 Best Reviews

Finding the best dehumidifier for your basement is essential. It’s no secret that your basement is likely the most humid and moist part of your house. Even warm and moist air can serve up a recipe of disaster as it sets up the perfect environment for mold growth. To ensure that your basement can be a place to frequently visit as opposed to a health risk, you should consider finding a professional dehumidifier for your basement. You’ll need one that will allow you to program the best setting so you have a desired level of humidity. Your basement will typically be a large area of your house, so it is important to find one that has the ability to cover basements and even large rooms in your house like a living room.

Basement or Crawl Space Dehumidifier?

One last thought before we get into the specifics of basement dehumidifiers. Do you actually need a crawl space dehumidifier instead? If your basement is actually small, hard to navigate, or an unfinished area, we instead recommend you look at some of the best crawl space dehumidifiers instead. These devices – while more industrial looking than their basement counterparts – are designed specifically for this use case.

Buying Guide

Before you buy a dehumidifier for your basement, it’s always important to consider some of the factors that will go into influencing your decision. Here are a few of them that need to be addressed:

The Size Of Your Basement

Of course, not all dehumidifiers are created equal. Likewise, not all basements are going to be the same size. So it’s important for you to consider the size of your basement while looking for a dehumidifier. If you have a basement that is about 3,000 square feet, a dehumidifier that is suitable for basements up to 1,500 square feet may not be appropriate. Most dehumidifiers you will find will be suitable for use up to 4,000 square feet.

Energy Saving

Not everyone that wants the best energy efficient dehumidifier for their basement is a tree hugger. While it may be great for the environment, there’s a real reason why finding an energy saving dehumidifier is important. The last thing you’d want to see is a high electricity bill because you were trying to make the air of your basement much healthier for you and your family. So rather than throw money into the constantly burning fire that is your energy bill, find one that will not only use minimal energy, but will also keep your bank account intact every month.

Draining Ability

At some point, the tank needs to be drained. And you have two methods of doing this: manual or automatic. In some units, you might have a pump that can help automatically drain the tank when it comes time to do so. However, if your unit did not come with one, you’ll need to purchase one. Also, your dehumidifier may come with its own drainage tube. Another thing to keep in mind is that some of them may not have a tube included. So instead, you’ll need a standard sized garden hose. Consider whether or not if draining the tank may be too much of a task for you while choosing a dehumidifier for your basement.


Why do you need a dehumidifier for your basement?

Since they are the lowest level of your home, they house the concrete foundation. Moisture enters your basement via the foundation. While there may be no sign of leaks or standing water, the moisture evaporates and creates humidity. Cold concrete walls and floors often play a role in creating humidity, especially in the summer months.

What size dehumidifier do you need?

This will depend on the size of your entire home. So if your home is roughly 1,000 sq feet, your basement will roughly be the same size. While you’re looking around, pay attention to the measurement of your basement. Some dehumidifiers may be ideal for a room that is 1,000 square feet in size. If it’s larger, then you’ll need to find a dehumidifier that is a step up.

At what point does humidity becomes a problem in your basement?

Typically, if your basement has a humidity level of 60% or more, it will become ground zero for mold growth. Not to mention, mildew and other allergens tend to favor these types of conditions. Remember, these are harmful to the health of you and your family. At the same time, mold growth can even lead to structural damage of your home.

How do you drain your dehumidifier tank?

Unlike smaller dehumidifiers, a larger dehumidifier has an entirely different method in terms of drainage. Your dehumidifier may come with its own drainage tube. While you drain it, you will connect the tube to the housing that is built into the dehumidifier itself. If there is no drainage tube, you can use a garden hose. The other end of the drainage hose will be either in a utility sink or a floor drain. At the same time, you can either drain the dehumidifier manually or automatically. If you wish not to drain it manually, you’ll need a pump that is either built into the dehumidifier or purchase one separately if none is present in the unit itself.
There are multiple ways to drain your basement dehumidifier using the automatic. If you wish to use the manual method, you can do so. Here are the following automatic and manual draining methods:

Automatic Draining Methods

  • Automatic Gravity Draining: What better way to automatically drain your dehumidifier with the use of good ol’ fashioned gravity? To set this up, find the drain port in your dehumidifier. Then unscrew the drain plug and attach a hose. Take the other end of your hose and place it in a suitable location where it can drain (like a floor drain or some other location that’s below the drain port). As an alternative option, you can raise your dehumidifier on a flat surface that can hold the weight of your dehumidifier. Be sure that your dehumidifier is draining properly before using this method.
  • Automatic External Condensate Pump: This is a method for dehumidifiers that do not have internal pumps. So you will need to purchase a separate pump in order to utilize this method. Using this pump, you can direct the moisture into a sink, out the window, or any location that is available for drainage. Most pumps will have the ability to push water up to 15 feet vertically or horizontally. Once it’s set up, be sure that the water is leaving the unit. Most pumps can easily reach a sink or out the window. Some users have even cut a hole through a door and ran a hose so the dehumidifier can drain outdoors.
  • Dehumidifiers with Built-In Condensate Pumps: This is pretty self-explanatory. These are dehumidifiers that come with an internal pump.

Manual Draining Methods

While it is not the most convenient method of draining, it is the easiest to understand. Once your dehumidifier tank is filled, your machine will shut off automatically. At this point, you can pull the tank out of the unit and dump it in the sink. You can also dump it outdoors. Once you replace the bucket, the dehumidifier will automatically start back up on its own.

Final Thoughts On Draining Your Dehumidifier

Draining your dehumidifier is something you must do almost every other day if you want to use it frequently. If you wish not to drain your unit manually, come up with a plan that will allow you to drain it automatically. This may include having to drill holes inside your home as part of a drainage path that you can create. For example, you can drain your tank outside. This means creating a hole through a doorway and running the hose through it. A recommended place for your drainage hose to run through should be a door that leads out to your backyard. This is a better location since the hose won’t run through a part of your home where people can trip on the hose itself.
