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.

Vremi 70 Pint Energy Star Dehumidifier


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.

Review of the Best Dehumidifiers for Basements

Let us now look at the best dehumidifiers for basements available in the market. In the end, you can compare and evaluate the option which is best for you to ensure you get the right pick.

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 45 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.


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

Best 30 Pint Model

TOSOT 30 Pint 1500 Sq. Ft. Dehumidifier

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


Dimensions: 15.0×11.7×20.7″

Weight: 32.0 lbs.

Decibel Level: 48 dB

Capacity: 20 Pints

(Max. Water Removal / Day)

We may earn commission from purchases made from our links, at no additional cost to you


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. (New DOE ratings have changed and this is now rated as a 20-pint model). 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.


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

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.


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

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.

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.

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.

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.

What Makes a Dehumidifier Great for a Basement?

Dehumidifiers gauge the moisture level in a room concerning the room’s overall temperature. They circulate the air in the room with a fan and then draw the moisture out of the air to reach a preset or desired level.

This ability to keep the amount of moisture level in a room at a comfortable level makes dehumidifiers essential for your basement, which is likely the most humid area in your home and frequently used for storage. Dehumidifiers will prevent mold growth and other damages from affecting your basement and belongings.

Some other advantages of a dehumidifier include:

  • Reduction of allergens: These units reduce the allergen levels in the air

  • Prevent dust mites: In addition to mold, dehumidifiers reduce the presence of dust mites

  • Discourage insects: Insects are far more attracted to humid and damp spaces than dry areas

  • Rust prevention: Keeping the air dry reduces rust

What Size Dehumidifier For Basement?

It’s important to consider the size of your room when choosing a dehumidifier. You also need to account for the device’s pint capacity, moisture reduction capability, and square foot coverage. 

However, most dehumidifiers state how much area they can effectively cover.

Types and Sizes of Basement Dehumidifiers

Some of the smallest dehumidifiers are about eight pints and intended for use in a cubicle, closet, or crawl space. Other units can reach up to 250 pints and are best suited for warehouses or industrial spaces.

Here’s a look at some of the most common sizes available:

  • 30 pint: For small spaces, a 30-pint dehumidifier will do the trick. They’re light, portable, and usually compact.

  • 50 pint: Medium-sized rooms are an ideal match with a 50-pint option.

  • 70 pint: A 70-pint dehumidifier can handle serious jobs such as basements or large spaces.

  • 100 pint: Although not the biggest available, this is one of the most popular large dehumidifiers. It can often handle large basements and houses.

You need to measure your space to decide which size you should use and what you can expect from your dehumidifier.

Basement Dehumidifier Comparisons

We put basement dehumidifiers head-to-head with other devices and systems to give you a true sense of which paths are most effective and how useful a dehumidifier can be. We looked at everything from moisture level to energy efficiency and comfort.

Here’s what we found out:

Basement Ventilation System vs Dehumidifier

A well-ventilated basement may have lower humidity levels than an enclosed and poorly ventilated space. However, installing a new ventilation system is more costly than buying a dehumidifier. You’ll likely only need a new ventilation system if your issue is serious.

Basement Air Conditioner vs Dehumidifier

While a basement air conditioner will lower the temperature in a room, it won’t remove the moisture from the air. You’ll need a basement dehumidifier to make your basement less humid. However, air conditioners are great if you use your basement as a living space and it doesn’t suffer from humidity issues.

Dessicant vs Compressor

A desiccant model is most suited to cooler environments, where it’s more effective than the average dehumidifier. We recommend desiccant dehumidifiers if your basement is cold.

If it’s warm, use a compressor – or refrigerant – dehumidifier to lower the room’s temperature while removing moisture.

French Drain vs Dehumidifier In Basement

French drains – trenches containing pipes that redirect surface water – aren’t alternatives to a dehumidifier and vice versa. They can resolve issues with flooding or leaking, but you’ll need a dehumidifier if you want to lower the moisture level in the air.

Frigidaire 50-pint Dehumidifier


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!

People Also Ask

Here are our answers to the most frequently asked questions regarding basement dehumidifiers.

Where to Place a Dehumidifier in the Basement?

You should place your dehumidifier in the most humid area of your basement. This allows it to function most efficiently. Ensure that the intake and exhaust are not blocked and that the dehumidifier is sitting flat and stable on the ground.

Will a Dehumidifier in the Basement Help the Whole House?

The humidity level in the basement may impact other areas of the house, but this is an indirect effect. A dehumidifier would have to be very large and powerful in order to impact the entire house.

What Humidity Should I Set My Dehumidifier to in the Basement?

This is a matter of choice. The dehumidifier should be set to about 40% humidity if you want your basement to be dry. This will significantly reduce any dampness or moisture collection in the basement.

How Often to Run Dehumidifier in a Basement?

You’ll likely need to run the dehumidifier constantly in a humid basement to keep the humidity level down. The moisture levels will rise when the dehumidifier isn’t running. Also, you’ll need to attach a drainage hose or regularly empty the bucket to maintain a comfortable level.

How Does a Dehumidifier Work in a Basement?

It’s the same as in any other area of your home. It detects the moisture level in the air and accounts for the temperature of the room. Then, it uses a fan to circulate air. It draws in moisture and stores it in a bucket.

Does a Basement Dehumidifier Help Temperature Control?

It’ll decrease the humidity level. This will make a humid room feel much cooler and more comfortable. Some dehumidifiers will also expel cool air with the fan cycle. However, they control humidity, not temperature.

Do I Need a Dehumidifier in My Basement?

Some basements don’t require dehumidifiers. Others become very humid, making it a risk to store anything in that space. Test the humidity percentage to check whether you need a dehumidifier.

When Should I Turn Off My Dehumidifier?

Your dehumidifier will turn off once the bucket is full if it runs continuously. If you have a drain hose attached, the water will pump out and continue to run until the desired humidity level is reached. You can turn the unit off once the moisture level in the air is comfortable.
