Types of dehumidifiers
Generally, there are three types of dehumidifiers: desiccant dehumidifier, thermo-electric dehumidifier, and compressor humidifiers. Desiccant humidifiers are not good choices for basements because they cannot control large rooms below ground level.
Thermo-electric dehumidifiers on the other hand, work best in warm rooms and may not perform a lot in cool and damp basements. The best type of dehumidifier for the basement should be compressor humidifiers as they are specifically designed to balance the humidity in damp rooms.
While these three are the major types of humidifiers, there are outstanding basement humidifiers that are commendable for specific categories. Perhaps, it is more beneficial if we rank the best humidifiers for the basement in terms of various performance indicators and other important factors.

How we picked the best dehumidifier
Most of the dehumidifiers featured here are ones that come with pumps, collection tanks and draining hoses. There is just one featured desiccant and one thermo-electric dehumidifier in the list.
There are three things that we considered in choosing the best humidifier for all categories: the amount of moisture removed every day, ease of operation and maintenance and coverage.
Regardless of the changes in the pint regulation by the Department of Energy Regulations in 2020 which demoted 70-pint to 50-pint, 50-pint to 35-pint and 35-pint to 22-pint, there are still models who have 70-pint moisture removal ability.
For large basement spaces, 50–70-pint capacity is best for large spaces of 2,000sq.ft. and up. 35-50-pint capacity would be enough for medium size basements while 22-pint is sufficient for small basements.
Moisture removal capacity is the main reason behind installing a dehumidifier in a basement. This is the reason why this one is highlighted in each of the listed dehumidifiers for you to have a visual of their coverage.
Anent to moisture removal capacity, coverage was also a primary factor in picking the best dehumidifier for basement. More often than not, high power and high coverage dehumidifiers come with built-in pumps, but the list proved that the wattage and power do not matter when it comes to coverage.
As such, you must understand that 50–70-pint capacity dehumidifiers are good for 2,000-4,500 sq.ft. basements. A 35-50-pint dehumidifier is commendable for a 1,200sq.ft. basement while 22-pint dehumidifiers are sufficient for 500sq.ft. and below.
You must, however, note that this breakdown in coverage works only for a single room with no divisions. This consideration should help you in making the best dehumidifier choice for your basement.
Ease of operation and maintenance
For the untrained eye, this is the first consideration that comes into mind. Is the filter washable? Does it have an auto-restart feature? Will it automatically defrost when it censors a drop in temperature? Is it portable? Is there a full tank indicator?
These are the common operations that a dehumidifier should have and fortunately, all that have been listed here have these and more. Some even have a smart system making them capacitated for remote operation or through a WiFi.
Basement dehumidifier buying guide
Since there are a lot of choices when it comes to dehumidifiers, you need to make a mental list of what to consider before buying one.
With the categories that we have presented, there are specific types of dehumidifiers for specific basements considering the differences in size, temperature and more. With these, here are some noteworthy factors to put into mind before finalizing your purchase for your basement dehumidifier.
What are the benefits of a basement dehumidifier?
At a general level, dehumidifiers act not just to balance the temperature and dampness of the room but also to encourage a more livable space by inhibiting the growth of molds, mildew and other insects that might take refuge in damp rooms like the basement. Specifically, basement dehumidifiers are also beneficial because of the following:
- Improvement of air quality: Having poor quality air circulating in the basement leads to various respiratory problems and diseases associated with the lungs and sinus in the long run. Installing a basement dehumidifier ultimately makes it a livable space.
- Quiet running: Dehumidifiers installed up top or in the ceiling sometimes disturb family time because they can be noisy. But dehumidifiers installed in basements and crawl spaces are known for their quiet performance.
- Energy efficiency: Basement dehumidifiers dramatically reduce the workload of ACs especially in environments with high humidity. The drier the air, the more the AC can cool down the space, hence, making the system cost-efficient.
- Maintenance of structural integrity: When there is over-moisture, wood structures of the home like beams and exterior trims are weakened. Having a basement dehumidifier whose chief function is to eliminate dampness helps in maintaining the structural integrity of wood structures in the basement.
- Cost efficiency: With the first four benefits that we have discussed, it is easy to say that installing a basement dehumidifier is a win-win choice as it encourages cost efficiency for the home.
With the emergence of newer models of basement dehumidifiers, so will its benefits. The dawn of smart dehumidifiers is changing the way we use them but for sure, our convenience, energy and cost efficiency are on the forefront. With good air quality flow in the basement, the following health benefits are also achieved:
- Reduced occurrences of allergies
- Lessens chances of acquiring chronic obstructive pulmonary disease (COPD)
- Offers a warm and cozy living space for relaxation
Things to consider when buying a dehumidifier for your basement
There are a lot of characteristics and features that make a good basement dehumidifier. Looking for one is already a daunting task but choosing the right one for your basement is really the cherry on top.
For you to at least have a working knowledge of what to look for when choosing a basement humidifier, here are some buying considerations that you should know before making the choice.
#1. Capacity and Coverage
Most often than not, basement dehumidifiers are ranked in terms of capacity. By capacity we mean the amount of water or moisture that it could condense in a day. This amount is measured in pints. Capacity here is interchangeable with power and not in terms of the tank size. As such, the more powerful the dehumidifier, the greater its capacity.
Note that there are three types of dehumidifiers in this category. Small dehumidifiers are portable, for small size basements and at a range of $50-100. Medium dehumidifiers on the other hand are at 35-50-pints, can dehumidify large rooms but might fall short on basements.
They range at $120-200. Large dehumidifiers are at 70-pints and are the perfect choice for basements. They range from $200-300.
The best humidifiers are those that run at 45dB and below. In general, dehumidifiers should resemble the humming sound of your AC unit. If it has a loud, whizzing sound, or a noise that sounds like a busy street or a traffic jam, you must return that immediately.
You would not find noise level labels in dehumidifiers. This is the reason why you must check reputable reviews about the product before buying it.
Note that all dehumidifiers come with a tank just with different storage capacities. The only difference resides on the drainage hose. Most of the time, drainage hoses are bought separately but having one is beneficial because it gives ease in emptying your collection tank.
You can do it on the drain floor, the sink, or even in basement windows. When it comes to ease in drainage, those with built-in pumps are sought after.
#4. Energy consumption
Depending on your needed humidity level, basement size, duration of use and humidifier capacity, you must know that the average energy cost of basement dehumidifiers would be at $15-60 a month.
The good news is that present models of dehumidifiers are almost all Energy Star certified. This means that they are more energy efficient by 30% than older dehumidifiers.
What is the best way to use a basement dehumidifier?
As have been presented, basement dehumidifiers come with a lot of benefits. As such, there are also various ways to get the most out of these useful appliances. If you are thinking of getting one for your basement, here are the ways to get the best out of your basement dehumidifiers.
- Place it in the right spot: The trick to getting the most out of a dehumidifier is to position it in a place where it gets good airflow. Whether they release air on a side vent or at the top, making sure that there is enough air space surrounding it is important for its performance. Closing the windows and doors also help as they do with air conditioning units.
- Manually set the humidity level: Almost all dehumidifiers have three fan speeds including a turbo mode. The optimal humidity level for any basement should be at 30-50% in areas with tropical or hot climates and 20-40% in colder climates. Anything higher than that may encourage the niching of mildew as well as mold buildup.
- Regular draining: The good thing about dehumidifiers is that they have a full tank indicator which glows when it is already time to empty the tank or shuts off the dehumidifier automatically to prevent overflow. During cold or rainy season, make sure that the tanks are regularly drained. It is also good to choose dehumidifiers with built-in pumps since they can easily be attached to garden hoses for easier draining.
- Maintenance: Of course, regular maintenance check also ensures that you get the best performance out of your basement dehumidifier. This means that you need to wash the air filter regularly to make sure that it gets quality air flow.
What comes along with this is cleaning the grills too. When the grills are dirty or there is a dust buildup, expect that the air flow becomes very slow. This is also an indication that you must wash your air filter soon. But for automatic dehumidifiers, part of their LED display would be an indicator light which signals that it is time to wash the air filter.
These are just basic steps to ensure quality performance from your basement dehumidifiers. By following them, you can surely get the most of out your basement dehumidifier.
Best setting for basement dehumidifier
According to Energy Star, which certifies the moisture removal capacity of dehumidifiers, the optimum humidity setting for a basement humidifier is at 30-50%. For areas with colder climates, the best setting would be at 30-40% during their considered hot season. In general, the best setting would be at 50%.
As have been mentioned, any humidity level beyond 50% can encourage the growth of molds and mildews as well as the niching of harmful insects. Using dehumidifiers at 20 degrees Fahrenheit and below also causes frosting so you also must be on the know about this.
What is the best basement dehumidifier brand?
When we are talking about the best brand for basement dehumidifiers, we are not just talking about one. For instance, in January of 2021, new consumer reports on the best dehumidifiers surfaced. Of these reviews, the following are consistently rated at the top of the list of the most reputable brands for dehumidifiers:
These brands have always been on the list for the best dehumidifier brands through the years. The others are reputable brands for all types of appliances in general so you can count on these when it comes to basement dehumidifiers too.
Does dehumidifier really work?
Given their popularity nowadays, we could really say that dehumidifiers really work. Having one whether in small offices, in an apartment or in a basement reduces humidity levels so that mites, molds and mildew do not pose allergy and asthma problems. It also dramatically reduces dust buildup in the home giving you some window time to focus on another place to clean up.
Most importantly, dehumidifiers are cost-efficient. With their ability to condense air, they are helping your air conditioning unit to be more effective. With all things considered, and with the consistent want of homeowners to have one, dehumidifiers indeed, work.
Do I need a dehumidifier for my basement?
This is not easily answerable by yes or no because truth be told, there are a lot of things to factor in before you decide to buy one. The following are some things to assess if you think that you need a dehumidifier for your basement.
- Moldy odor: This type of smell is spot on so once you smell that moldy odor, no matter how much you clean and bleach the space every now and then, it is time to get your basement a dehumidifier.
- Frost buildup: If you have constant frost buildup in your basement or around cooling services such as the air conditioning unit or the entire HVAC system, you might need a dehumidifier soon. If you allow it to stay that way, expect cracks or rotting along your walls, flooring, the ceiling and other structures in your basement.
- High humidity areas: For humid locations experiencing more than 50% of humidity level in specific seasons, you might need a dehumidifier to inhibit the hike of condensation levels in your basement. In locations like this, the dehumidifier aids the HVAC system in balancing the humidity levels in the basements of such locations.
How does a dehumidifier work?
It is valid to know how a dehumidifier works given its pros and the multitude of brands that are banking on it. Basically, this appliance works by converting hot air from its fan and into the coils. As it goes through the coils, the air is condensed, collecting drops of water, and storing them in a tank which is attached to the dehumidifier.
With the condensation process, drier and cooler air flow is released from the side vent. On an average, a dehumidifier works to bring down the humidity level of any room by 30-50%. Thankfully, all dehumidifiers come with preset levels and a monitor where you could key in your desired humidity level for the home.
How to choose a dehumidifier for the basement
We have covered the factors that need to be weighed in before buying a basement humidifier. The other task is to look for specific features to choose the best humidifier for your basement.
There are unique features in some models that you would not find in the others. This gives them a notch up from the rest. And needless to say, these are the types of dehumidifiers that you should be on the watch for.
Automatic controls: Dehumidifiers have default controls that are present in all types and models. These controls are humidity level presets including a turbo mode and full tank indicator. But other than these, a good basement dehumidifier should also have the following automatic controls:
Automatic reset: Having auto controls are helpful if you are not always around to monitor your dehumidifier. Having an automatic reset feature is beneficial for your safety especially when there is a power surge and after the timer goes off.
Humidity sensor: It also pays that you do not have to key various humidity levels every now and then. Choosing a smart humidifier with a humidity sensor helps a lot not only in maintaining the necessary humidity level for the room but also in auto-defrosting when the temperature drops.
Frost censor: This one works whenever the system detects frost buildup in the coils. When there is so much frost, the dehumidifier cannot work efficiently. As such, it pays to have a humidifier with a frost censor that will automatically shut off the dehumidifier to avoid over-frosting the coils.
Ducting: Not all dehumidifiers could do the work for two separate rooms or could be tucked in small basement spaces. Ducting capacity means that a humidifier can service two rooms at the same time. This is a unique feature of only a handful of dehumidifier models so best choose those that have a good ducting capacity.
Digital controls: Aside from the automatic features of a humidifier, you also need to consider other helpful digital controls. This includes the following:
Filter light indicator: It pays to have a light indicator that tells you if it is time to wash your dehumidifier’s filter. It saves you a lot of time, maintenance costs and ensures that the dehumidifier performs well continuously.
Humidistat: While the humidity level presets are present, it is also helpful to have a humidistat that signals the dehumidifier to shut down when the sufficient humidity level for the room is already achieved. This one monitors the drop and rise in the room temperature and is considered as a part of the smart controls of a dehumidifier.
- Tank capacity: You must be wary of the tank capacity of a humidifier because some large dehumidifiers have small collecting tanks. If there is a mismatch between the pints per day and the tank capacity of a dehumidifier, you will have to empty that tank every now and then. 1.5gL to 2.5gL is already a decent tank capacity.
- Wheels: This has a lot to say with the portability of a dehumidifier. By portability we do not only imply that you get to move it at any point in the basement but also has something to do with easily moving it when you take it out for cleaning.
Frequently Asked Questions
To wrap everything off about basement dehumidifiers, here are some FAQs that might come in handy. It can serve as an additional buying guide to help you narrow down your choice for the best dehumidifier in your basement.
How much does it cost to operate a dehumidifier in your basement?
Fortunately, the game has changed for dehumidifier manufacturers as they have really banked on energy and cost efficiency. Present models only cost 4.2 cents when you run it for a straight hour. Try running that for 24hrs and you only pay a dollar or $30 a month.
Given this rate, you are most likely to pay more on the wattage of your television and your AC than on your dehumidifier no matter how big it is. So, ideally, you get the best out of the functions of a basement dehumidifier without paying so much for them.

And given their energy consumption and their line of benefits, 12hrs might not even suffice.
When to use a dehumidifier in the basement?
Dehumidifiers are bought and installed precisely because there is a need for them in the basement. Here are six reasons to use a dehumidifier in your basement.
- Musty smell in the basement: When moist is constantly trapped, its accumulation turns into a musty smell. If you have this unwanted smell circulating in your basement, you should start using a dehumidifier.
- Water condensation in the basement window: Constant condensation in the window looks like it is frosted but, these are moist, and water trapped in basement window sills. If you just let this go on without the intervention of a basement dehumidifier, you are risking the structural integrity of your window trims and other wood structures in the basement.
- Basement leaks: If leaks in the basement are becoming more constant especially after heavy rains as the walls sweat and cracks leak, you surely need a basement dehumidifier to dry that down.

Can I leave my dehumidifier on all day?
Yes, but not necessary. If the dehumidifier is at its peak performance, it could balance the humidity level of the basement or any type of room by 50% at a continuous running time of 12hrs. But if you want to make sure that you get a cooler, fresher air flow for 24hrs, it is also a viable option.
Will a dehumidifier kill mold?
No. This is a common misnomer among homeowners. Dehumidifiers do not kill mold they just lessen the humidity level of the room to inhibit their growth. Molds thrive on dampness and over-moisture. Since dehumidifiers relieve the basement with moisture, they cannot thrive when they are constantly around to the job.
