The basement is the place of the house that is most affected by mold and dampness and that is because of the high level of air humidity that creates condense. For you to solve this problem and rid your house of mold and mildew, you must resort to the help of a dehumidifier that is powerful enough to capture the excess water moisture. Plus, it needs to be easy to use and convenient so you won’t have to worry that the water will spill when the bucket gets full.
Top 12 Basement Dehumidifiers Comparison
Tailored for use in spaces of up to 1400 square feet, this 70-pint dehumidifier from Frigidaire is the best option for removing excess moisture from the basement.

Noteworthy Details You Should Be Aware Of
Have you ever wondered what is the difference between a cellar dehumidifier and a conventional one that can be used in your bedroom? The cellar type is simply a portable device which comes equipped with various features and functions in order to operate more efficiently in a basement. The converse of the statement that it cannot work as well above ground as it does below ground, is not true, however. Most units that work well above ground are equipped with a plethora of features, so they are able to handle environmental variables unique to a basement, most notably colder temperatures. Nowadays, they are the best solution for removing mildew odor and prevent mold from growing. Low-temperature dehumidifiers are perfect for cooler climates, as they will continue to draw moist at lower temperatures. Therefore, if you have an extremely large cellar, it is good to know that there are numerous devices that have been tested for reliability and effectiveness, especially at low temperatures.
Excess Moisture Symptoms
To make sure that you are taking the right course of action by adding the moisture removal device to this particular area of your home, there are a few symptoms or sings that you can look for, more precisely:
- Measured humidity levels higher than 55%
Use a hygrometer to measure the precise humidity levels in the basement yourself. The quite inexpensive product will provide you with an accurate reading in a matter of minutes, anything over 55% clearly indicating that a proper habitat for mold and mildew is created.
- Dust mites
If you experience dust mite allergy symptoms when you are in this area, it is a rather clear indicator of high moisture levels. As one of the most effective methods to keep dust mites at bay is preserving humidity levels below 50%, it’s more than obvious why their presence is a sign worth taking into consideration.
- Rot and decay
Rot manifests in many ways, and there are quite several different colorings you can encounter, including brown, white, grey, black, and even blue rot. It can even change the structure of wood without any visual indicators, so keep this in mind too. Evidently, any sign of rot is a strong indicator that moisture is high and that measures need to be taken immediately.
- Musty smell
Odors are exponentially intensified when humidity is high, and when an unpleasant musty smell emerges, changes are that moisture is at inappropriate levels. The musty odors can signal various issues, including rot and mold growth.
- Tangible dampness
When you go down in the basement and you can actually feel the dampness of your skin, then you don’t need any other clarification that moisture levels need to be lowered urgently.
- Peeling/cracking paint
Check the painted surfaces in the basement as they can show you whether there is an actual need for a dehumidifier or not. If any of the following draw your attention, then levels are indeed higher than normal – blistering, cracking, or peeling paint.
- Frost on cold surfaces
When you notice frost or ice building up on surfaces in this area, it is another sign that you should further check into humidity conditions.
Moisture Removal Device Buying Guide
Like many other devices, dehumidifiers come in all shapes, sizes, and types, making it hard for customers to pick the right one. To narrow down their options to the best models, people need to know which are the aspects that really matter.
Unlike room dehumidifiers, the basement type is larger because it needs to rely on a larger motor with a higher suction power. When choosing one, you must read its specifications to be certain that it is large enough to handle the large area. Different models are designed for different room sizes that can reach 2,000 sq. ft. This will guarantee that it will be able to absorb the humidity from the entire room, regardless of how big it is.
Given that space is larger, the amount of water absorbed from the air is also larger so the device should have a bigger capacity. Cellar dehumidifiers have a large water container that can absorb up to 100 pints of water per day. An efficient model should have a capacity of around 70 pints in order to provide the expected results.
Having to remove so much water from the air on a daily basis means that the water container will be filled very fast and should be emptied as fast. If this involves you checking on it every couple of hours, it will seem cumbersome to use. Therefore, it must include a drain pump that will empty the water on its own whenever the container is filled.
If features like quiet operating or a stylish design are not important, some other features are essential and increase its convenience and performance. A shut-off feature that will turn it on when needed or a humidistat to control air moisture will come in handy and minimize maintenance.
Alternative Excess Humidity Prevention Methods
Until you round up the money to get yourself a moisture removal appliance for this particularly problematic area of the house, or if you simply want to aid the device you bought by controlling humidity through extra means, you should take up the alternative methods we present here.
Control from the inside:
- Repair leaks in house: The most common indoor moisture issues are caused by plumbing problems and leaks, so you must inspect and repair leaky toilets, pipes, fixtures, and all plumbing for that matter to ensure moisture won’t drip into the cellar and create excessive dampness.
- Seal ductwork leaks: Ducts have the role of carrying cold and warm air around the house, but in this specific area they can potentially crease humidity if there are leaks present which allow moist air to seep out. Evidently, if you do spot any leaks, you must seal them immediately.
- Dryer vent: A huge amount of moisture is produced by the dryer, and to prevent the wetness it produces from becoming an issue, you must install a vent to direct the moisture produced outside.
- Exhaust fans: Remember to always run exhaust fans in the kitchen and bathroom when performing certain tasks. Run the fans in the kitchen when you cook to get rid of the vapors which form, and run them in the bathroom when you shower or bathe.
Control from the outside:
- Maintain the sump pump: Regular inspection and maintenance for the sump pump can spare you a lot of trouble as its purpose is to collect water from around the foundation, keeping your home protected from flooding, potential structural instability, and high humidity.
- Clean the gutters: External water is very dangerous, and the role of the gutters is to collect it and move it away from the house. For them to work properly, however, regular cleaning and clearing of debris is required, so make sure that you tend to this task.
- Fix the foundation: Openings in the foundation are troublesome for the cellar as moisture enters through them. Regardless if you buy the needed materials for the repair of the leaks and holes or if you call in an expert for the job, you have to tend to these issues immediately as they pose a great threat.
- Waterproof the walls: Generally, foundation material is porous, which means that water can easily seep in the basement through it. Thus, to safeguard against high humidity, you can coat the walls with a waterproof material.
- Put up a plastic barrier: If your basement has a dirt floor, you must immediately cover it with 6mm plastic sheets to prevent water vapor from entering through the soil.
- Increase ventilation: On non-humid days, you can increase ventilation in this part of the house by running fans, using exhaust vents, or even opening the windows to increase air flow and prevent condensation as much as possible.
- Close windows when humidity is high outside: When the relative humidity outdoors exceeds 50-60%, close the windows in the basement to prevent the humid air from entering and condensation from forming. Generally, you need to do this during spring and summer as these are the seasons when humidity is at its highest.
- Insulate cold water pipes: A common place for condensation to form, cold water pipes are the usual suspect as they are cooler than their surrounding area. What you must do is buy pipe insulation and wrap the pipes with it to prevent moisture from collecting on them.
- Extra insulation for exterior walls: If the walls are warm, condensation won’t form on them, which means that you should insulate the exterior walls. However, make sure that you do this only after addressing leaks and water entrances from the outside as, otherwise, you risk trapping water behind the insulation, which will inevitably lead to mold growth/.
How We Tested
Moisture removing performance
To test and see if our picks are as great as their manufacturers say they are when it comes to moisture removal, we used each of them in a highly damp basement to see if they can handle lowering humidity levels and how effective and efficient they are at this procedure as well. Each product was left to run its operation for 24 hours in order to fairly rate its performance.
Emptying the tank
To establish how easy or hard it is to empty the tank, we took it upon ourselves to do this procedure, having a first-hand experience with how the tank is removed, emptied, and then put back in its rightful place.
In order to test and see exactly how much noise each device outputs when it operates, we turned them on and placed a decibel meter approximately 1 foot away. We compared readings to each other and to the output that pother household appliances deliver in order to figure out if they would become a nuisance if you were to sit in the same area with any of our dehumidifiers.
Ease of use
When we tested how convenient and easy to use each product is, we took several factors into consideration. We tested to see how easy it ease to clean and maintain them as these are procedures that must be done on a regular basis, how intuitive the settings put at your disposal are, and how easy it is to relocate the devices whenever needed, thus taking design into consideration as well.

The Risks of High Humidity
Since basements are not actual living spaces, many people overlook the problem of a high humidity level because they are not aware of the dangers it implies. Although you do not get in direct contact with the air for long periods of time, it can still affect your life and you are at risk of suffering on multiple levels. As such, you must monitor and adjust humidity at all times if you want to avoid the following risks involved.
Major health problems
It is true that you rarely go in the cellar and that you spend little time there but this does not mean that the mold spores in the air cannot travel throughout your entire house. If it becomes a thriving environment for fungus and bacteria, the air rapidly spreads around the house, causing major health issues like allergies, asthma, or other respiratory problems.
Weakening of your house’s construction
Since it is located at the bottom of your house, allowing humidity and mold to get inside the walls can lead to damaging the structure and stability of your house. As such, if you want to avoid further damage that can have severe consequences, you must not allow mold spores to take over the room. With humidity starting from beneath, it won’t be long until your entire house will be affected by mold and mildew.
Damage to your belongings
This area of the house usually has a storage purpose, being the perfect place for keeping items you use occasionally and that you want out of your way. Keeping them in improper conditions can lead to irreparable damage so you should focus on adjusting the humidity level between 30 and 50%. If you have also designed a recreational space here, you have even more reasons to find a solution to high air moisture that can affect the aspect and lifespan of your belongings.
Why Should You Use an Odor Absorber
The basement is a problematic area of the house because it is not a living space and the conditions are not optimal for developing a clean and safe environment. The constant humidity, depositing all sorts of items, and poor ventilation can lead to an unpleasant musty smell that can soon become hard to get rid of. Once the heavy smell of dull air, moisture, and mold starts to take over, it is up to you to find the most effective odor absorber.
- Odor eliminators are products that contain natural minerals with odor-absorbing powers that can neutralize all sorts of bad smells from garbage, pet urine, smoke, mold, and mildew. Gonzo odor eliminator, for example, is a product that consists of volcanic minerals that are electrically charged to act as a magnet that attracts and retains odor particles from the air. The minerals are 100% safe and chemical-free so that they do not affect your health and are not dangerous for pets or children.
- The main advantage of the absorber is that it naturally repels airborne odors without the help of artificial fragrances that would only mask odors without actually removing them. Odor absorbers are environmentally friendly and they do not release any impurities into the air.
- Another great benefit of using this product is the fact that it is reusable and rechargeable, being able to last for up to 2 years. One bag is powerful enough to remove odors for 30 days and after this period, all you will have to do is leave it outdoors in direct sunlight to allow the volcanic rocks to recharge and get ready to reabsorb odors. Nonetheless, this is the most effective and easy to use method of refreshing the room and solving the musty odor problem.

F.A.Q. Why is it necessary to place a dehumidifier in the basement?
From its construction, the basement is a damp and humid space as ventilation is not as great in it as it is in the rest of the house and because it is situated at a lower level. Thus, there is a dependency on the dehumidifying device in order to ensure humidity does not exceed safe, healthy levels.
Does the moisture removing appliance help make the basement a habitable area?
Yes, due to the fact that it lowers moisture levels, the dehumidifier makes the basement habitable. As high humidity settles in this area, mold and mildew inevitably appear. These fungi present a great threat to your health, especially if you suffer from asthma or allergies, so you must do your best to preserve healthy moisture levels if you intend to use the basement as an extra room.
Does the continuous drain option make a difference?
What makes the continuous drain option so desirable is the fact that it eliminates an annoying requirement – you will not have to empty the water reservoir anymore when it gets filled, as the water is eliminated in a drain or outside the house through a window, depending on the location you choose for the water to be transported to. Thus, you will be required to do a lot less maintenance work.
Should I look into the operating temperature of the appliance?
Yes, seeing how you intend to place the moisture removing appliance in the basement, it is necessary to look into this spec. otherwise, you risk making a useless investment as the appliance will not be able to operate at all times, stopping or malfunctioning when temperatures drop below a certain point. Seeing how this is an often occurrence in the basement, it is important to make sure the dehumidifier can handle low temperatures without a problem.
What is the normal humidity level for a basement?
Just like in any other room or space, you should keep a relative humidity level of approximately 50 percent for mold and mildew to not make an appearance and ultimately make this area of the house inhabitable and dangerous for your health to be in it.
As it is a naturally damp space in which mold and mildew will thrive uncontrollably if you do not take any action toward establishing and maintaining a decent humidity level, the need for a dehumidifying device is understandable. Our favorite product, by far, is the Frigidaire FFAD7033R1 which handles removing up to 70 pints of moisture per day. Not only this, but it comes with numerous convenient features, including the 24-hour built-in timer that helps control utility bills, and the Ready-Select controls which provide an intuitive use of the device.
Another selection we consider you should revisit and think about purchasing is the Friedrich D70BP which features automatic defrost in order to keep the coils safe and prolong the lifespan of the appliance. Furthermore, it allows for continuous drainage and is capable of removing up to 70 pints of moisture per day. However, if pricing is a big concern for you, we would instruct you to invest in the Ivation IVALDH70PW as it comes at a cheap price, yet still delivers a surprisingly qualitative performance as it removes up to 70 pints of moisture over a 24-hour period.
