What Can You Expect After Adding a Dehumidifier to Your Basement?

A dehumidifier has several benefits it will bring with its installation. These include:

  • Prevention of mold growth on the basement walls
  • Fresher, odorless air that does not feel clammy
  • Dampness of walls and the floor is prevented
  • Rotting and decay of belongings stored in the basement is prevented

We’ll get to which dehumidifier model is the best choice for you in a bit, but one thing is absolutely sure, regardless of the one you invest in; a dehumidifier will definitely make your life easier. If you invest in a high-quality dehumidifier for your basement, chances are you will never regret your decision.

You won’t need to spray insecticide ever so often to kill the insects that grow in the damp and dark. Moreover, the basement will not need constant cleaning or even repainting and scrubbing of walls. Most importantly, you won’t have to hold your breath each time you go down to get some of your stuff. The air will feel fresh and clean.

Additionally, investing in a dehumidifier that can ensure a particular temperature is even more useful. This will allow you to set up the required temperature. Not only are health problems prevented, but a dehumidifier is also able to switch itself on after a power outage making it hassle-free to own and run one.

How to Choose a Basement Dehumidifier

This is the obvious question that is bound to cross your mind once you’re convinced you really need to invest in a top-quality dehumidifier for your basement. So, what are the actual features that you should consider before making a purchase? Let’s have a look at some of these:

Spaciousness and Size

The very first thing to consider before making any decision is to deduce the size of your basement. Doing so allows you to then decide how large of a dehumidifier you require. If you have a larger basement, then you’ll require a dehumidifier that can collect a larger amount of moisture and one that is suited for larger spaces.


This is important as some dehumidifiers, although suited for your space, will fail to work if the level of humidity in your basement is too high. Some areas experience worse summers and higher levels of moisture, making a few models inefficient for your use. Moreover, your basement could possibly be built in a way that causes it to be damper and moldier than others in the same region.


Not all dehumidifiers are portable. If you’re interested in switching positions or moving it for use in other parts of your house, then you need to consider this. Also, it's quite interesting to note that there are dehumidifiers that are available for controlling humidity throughout your house. Although, a great investment, these models are not portable.

Water removal

You may not have a setup that is suitable for drainage that works due to gravity in your basement. You may then need a dehumidifier that drains out water automatically through pumping.

Our Review

This dehumidifier is not only portable but also very stylish, allowing you to place it anywhere without killing the look of your room or basement.

Moreover, the 6.4-pint bucket capacity allows the device to soak up a good amount of moisture in one go whilst alerting you when it gets full. This alert helps prevent overflow and damage to the equipment. The tank can be easily emptied out using the continuous draining option and can also be emptied out manually.

This Energy-Star rated machine helps conserve energy and reduce your electricity bill as compared to an air conditioner. Also, the easily removable dust filter enables easy cleaning and maintenance of the equipment. In addition, the three setting modes allow you to run it either on normal, turbo or auto-defrost.

Friedrich 70 Pint Dehumidifier with Built-In Drain Pump, D70BPA


  • Continuous drainage feature for auto water removal.
  • 24-hour timer to allow easy resetting of the appliance.
  • Equipped with an internal pump that allows you to manually drain out the tank in seconds.


  • Not durable.
  • Issues with drainage.

Our Review

Like other dehumidifiers on this list, this one is also Energy-Star rated meaning that it has been specially built to conserve energy and hence reduce or at least not contribute to global warming. Moreover, the 70-pint capacity makes it perfect for larger basements, and the continuous drainage feature allows easy water removal from the tank.

It features a built-in drain pump that can pump water up to 15 ft. both horizontally and vertically, making even manual tank emptying extremely easy. The unit displays room temperature and humidity level for easy monitoring. Plus, the removable front condensate bucket is equipped with a carry handle for maximum ease.

The 24-hour timer makes it easy for you to set the equipment up to work on a fixed schedule automatically. Since it comes with the best pump any dehumidifier has to offer, it makes up for any cons that this device may have.

Bottom Line

This is a great dehumidifier if you consider the built-in pump and continuous drainage features. However, it has been reported to have broken down too soon, and issues with drainage and bucket removal have also been reported.

Although, equipped with features that not all dehumidifiers offer, the product is not very durable and seems to have poor quality. So, you’ll have to decide between getting innovative features and making peace with drainage issues.

Best Wall Mounted Model:
IW25 In-Wall Mounted Dehumidifier

Innovative Dehumidifier Systems IW25 In Wall Mounted Dehumidifier removes 25 PPD for 1500 sq ft


  • Washable air filter for easy maintenance.
  • Epoxy coating on the coil makes it durable.
  • Silent operation to allow you to enjoy your peace.
  • Perfect for those that prefer wall-mounted equipment.


  • Not suited for crawl spaces.
  • Requires the perfect size and shape wall frame for mounting.

Our Review

The IW25 In-wall mounted dehumidifier is the best of dehumidifier models designed to be mounted onto walls. It can be mounted easily between 16-inch wall studs and can drop down humidity levels easily in an area up to 1500 square feet in size. Moreover, the humidity setpoint is also adjustable; it ranges from 30 percent to 90 percent.

Operating at 47 decibels, this unit prevents you from hardly noticing it that it’s running in the background and keeps both headaches and noise pollution at bay. Plus, the automatic restart feature after a power outage makes life even simpler. You won’t have to restart the equipment manually. In fact, you won’t even have to readjust the settings either.

The dehumidifier drains automatically into existing plumbing which it has to be connected to upon installation. As a result, it successfully removes moisture, mildew, mold, allergens, and bacteria and helps keep the air fresh, clean and odorless.

Bottom Line

Safe to say, this is an excellent dehumidifier that can be wall mounted and hard piped. It works like a charm in smaller basements. Its only drawback is that it cannot fit into crawl spaces and requires a perfect frame for mounting.

Else, the equipment will either break or fail to run properly. Otherwise, for a mounted model, it is one of the best you can get your hands on.

TOSOT 20 Pint 1,500 Sq Ft Dehumidifier Energy Star - for Home, Basement, Bedroom or Bathroom - Super Quiet (Previous 30 Pint)


  • Eco-friendly as it does not use up too much energy.
  • Power outage restart feature to allow hassle-free restarting.
  • Silent operation that makes it easy for you to enjoy your peace.
  • Excellent for small rooms that makes it perfect for bathrooms and moderate-sized basements.


  • Not very reliable.
  • Poor drain plug design.
  • Drain hose not included.

Our Review

Yet another model by Tosot, this is categorized as one of the best 30-pint models that are perfect for smaller rooms and basements that are up to 1500 square feet in size. The TOSOT dehumidifier is not only portable due to its wheel and handles, but it is also Energy-Star rated. This makes the equipment eco-friendly and helps in reducing billing costs that are usually incurred by air conditioners.

Moreover, the device is also extremely quiet which makes it user-friendly as noise pollution is abstained. The continuous drainage hose outlet makes it easy to keep the tank empty automatically and reduces worry. Similarly, features such as power outage restart allow you to keep your settings while the system restarts automatically in case there's a power cut.

The dehumidifier cleans up the air by soaking moisture, thereby reducing the chances of mold and mildew build-up. Also, allergen build-up and health-related issues are kept at bay.

Bottom Line

Undoubtedly, this is the best of models that offer a 30-pint tank. However, while it is perfect for smaller basements, it is not very durable. Its poor drain plug design and reported leaks make it a slightly unreliable option.

Even though the pros outweigh the cons, it is important to note that this equipment has been reported as one that does not last very long. But, if you’re someone that does not mind replacing the units after a short time of use given the unit’s efficiency, then this can make a good option.

Most Energy Efficient:
Frigidaire 50-Pint Dehumidifier

Frigidaire High Efficiency 50-Pint Dehumidifier with Built-in Pump, White


  • 6ft long power cord makes it easy to place anywhere.
  • Electronic controls that make the appliance easy to operate.
  • Digital humidity readout that makes it easy to monitor humidity.


  • Bad quality as it does not last for more than a few months.

Our Review

Once again, Frigidaire’s 50-pint dehumidifier is Energy-Star rated. This makes this equipment eco-friendly and helps you conserve energy and reduce billing costs. In fact, it can be deemed perfect as an alternative to air conditioners that cost you a chunk of money.

The device successfully prevents mold, mildew and allergen build-up by removing the excess moisture present in your basement. It is the go-to-pick for people with breathing problems caused by bacteria present in the air. Not only does this dehumidifier make your air feel cleaner and fresher, but it also makes it odorless.

In addition, the portability of this dehumidifier allows you to place it wherever you prefer easily and also allows you to move it to a place that has a pipe connection. The humidity control feature allows you to set the machine to your preferred humidity level. Meanwhile, the 6 ft. power cord is self-sufficient, making the device easy to plug in anywhere without an extension. The long power cord also makes it a good option for those who have a perfect space for placing the dehumidifier but do not have a power source nearby.

Bottom Line

Although a great product with great features, it does not have the best quality parts nor is it long-lasting. Moreover, it is only suited for those with smaller basements and those that do not mind re-purchasing the product every few months.

It has been reported to have malfunctioned entirely or partly, and the customer service has also been poor. It is essential to ensure that you check that warranty is included while making your purchase.

FRIGIDAIRE 70 Pint Dehumidifier with Wi-Fi Controls


  • Suitable for large basements and big rooms.
  • Digital humidity readout for easy monitoring.
  • Electronic controls which make it easy to operate.
  • 24-hour timer assists automatic shut-off and reset.


  • Not very durable as it does not last very long.
  • Poor quality as parts have been reported to malfunction.

Our Review

The number of models by Frigidaire on this list only proves how its products are one of the best for your basement. This 70-pint model is not only sleek and stylish, but it is also white in color, enabling it to merge effortlessly into its background.

It is one of the quietest dehumidifier models available out there and is a must-have for those that are irritated by noise and would do anything to keep their peace. The device works smoothly with a 115V outlet and removes moisture efficiently. This, in turn, prevents bad odor, mold, mildew, allergen buildup and clustering of bacteria that leads to breathing problems.

The low-temperature operation feature conserves both energy and saves money. Meanwhile, features including electronic controls, digital humidity readout, 24-hour timer and control lock make this equipment very user-friendly. Also, its Energy-Star certification and UL listing promise to help you simultaneously conserve energy and protect the planet.

Bottom Line

Just like many other dehumidifiers, this one does its job well only until it breaks down. It has been reported to have failed both under warranty and outside warranty, making it not a very good choice for those that aren’t interested in re-purchasing equipment after every few months.

However, until it's running, it’s the best at what it does. Also, it is very, very quiet; a thumbs up for those that would do anything to keep their peace and quiet.


It should have become easier for you to deduce which dehumidifier you require for your basement after comparing all of the best models available. Regardless of your choice, it is important to note that a dehumidifier in general, has a lot of advantages. These include fresher air, mold and mildew prevention, prevention of respiratory troubles and odorless air. Moreover, it helps reduce billing costs and runs automatically making it hassle-free to own one. So, to tackle your smelling and pollutant-filled basement, you now know what to do!
