The Best Dehumidifiers for Basements – Our Top Reviews

best dehumidifier for basement

A moisture-filled basement is no way to live – it’s as simple as that. But depending on home’s structure and your geographic region, relieving your home of trapped humidity may be easier said than done. Some folks believe that a standard air conditioning unit or a built-in HVAC system can alleviate these problems on their own. But neither of solutions provide the flexibility and situational productivity of a stand-alone dehumidifier unit.

This is doubly the case for homeowners with an overly-humid basement, as it turns out. In these locations, mold and mildew can thrive if ambient humidity is allowed to regularly permeate enclosed spaces. When placed effectively, a basement dehumidifier can help suck up this excess ambient moisture in a matter of a few hours and actively prevent humidity from becoming a problem for your basement ever again.

As you might expect, though, not all dehumidifiers units are built alike. In fact, some are not even built for long-term basement use at all! In order to address your basement’s ongoing humidity problem, you’re going to need a reliable dehumidifier model that has both the ability to suck up a respectable volume of ambient moisture per day and the internal capacity to avoid needing to empty the tank every few hours.

When it comes down to it, you’re going to need to spend some time comparing each of the industry’s leading dehumidifier models based upon their core specifications and features. Luckily, you won’t need to search far and wide to find pertinent information in this domain if you read through this guide to the best basement dehumidifier. Herein, you’ll find a wealth of insights into the process of choosing a quality dehumidifier, as well as reviews for the top seven dehumidifiers available to consumers today.

By the time you finish reading this guide, you should feel more confident at finalizing plans to purchase a dehumidifier for your basement. Regardless of which model you choose, you shouldn’t delay your plans to purchase the unit as soon as possible. Mold, mildew, and more can show up in a humid basement at any moment, making the need to eliminate it all the more urgent.

Basement Dehumidifier Buying Guide

Addressing your basement’s humidity problem can feel like an endless battle. Just when you think you’ve resolved it, a rainstorm rolls in and reseeds your lower level with the kind of humidity that gives rise to mildew and mold. In many cases, an auxiliary dehumidifier unit can act as your first defense while you work on a long-term solution for preventing humidity from entering your foundation.

Purchasing the appropriate dehumidifier is easier said than done for many, though. Dehumidifiers today come in a variety of different sizes, each of which come with differentiated capacities to draw in ambient air vapors and capture the same in an appropriately-sized tank.  That aside, the proper dehumidifier unit for your basement may well depend on outstanding factors, such as the size and temperature of the intended use room.

In order to take these factors fully into account, this concise buyer’s guide will provide you with industry-specific details about the kinds of features that typically show up in contemporary basement dehumidifier listings. Each of these critical criteria may impact your final dehumidifier selection, so be sure to read through this entire buyer’s guide before finalizing your online purchase.

Important Features

First up, let’s crack into the kinds of features you should look for in a high-quality basement dehumidifier. While all of these features need not show up in every model on your list, your final selection should include at least a few if your planning to rely on that dehumidifier unit for an extended period of time. Many of the following features directly affect their unit’s performance as well, making it all the more imperative that they appear in your next dehumidifier.

Hose Drain Outlet

house outletIf you’re intending to use your dehumidifier continuously (either year-round or seasonally), then you might consider looking for a model with a hose drain outlet. Though a minor component, this type of outlet allows you to forgo the need to constantly empty your unit’s condensation tank by installing a continuously-active hose drain.

When installed properly, this type of hose drain allows for gravity to do the heavy lifting when it comes to clearing your dehumidifier of its collected moisture. Whether with a common garden hose or a piece of devoted tubing, these hose drains can be set up to empty into a nearby floor-level sewer drain, thus eliminating the need to empty the unit’s tank often during high use scenarios.

Auto-Humidistat

Smart devices are all the rage these days, so it is only appropriate that you purchase a dehumidifier that is “smart” enough to know when it needs to turn on and off. That’s precisely what you’ll get in a unit with an auto-humidistat, which is a programable component that can communicate your desired level of humidity directly to the unit’s operating computer.

When you activate auto-humidistat functionality, you’ll set a high maximum and minimum level of moisture that is accessible within the use space. Then, your humidifier uses its onboard sensors to continuously analyze the air quality content in its area. Once it senses humidity over the top threshold, the unit will turn itself on and remain active until the ambient humidity in the area drops below a bottom threshold.

Condensate Pump

Basements with crawl spaces and other unusual areas where humidity congregates will likely need to make use of a condensate pump system.  In essence, these pumps allow for water collected by a dehumidifier unit to be driven upward against gravity and into an off-site collection or disposal point (such as a floor-level sewer drain).

If you find yourself in a situation where this kind of auxiliary set up is necessary to properly aerate your basement, you may need to do extra research to find a condensate pump that is compatible with your current dehumidifier. That being said, some premium-grade dehumidifiers come with a condensate pump built in, allowing for more flexible usage over the lifespan of the unit.

Auto Defrost

Many dehumidifier units make use of a cold condensation unit in order to convert ambient humidity back into common water. As a result, these units can run internally cold and are susceptible to freezing up under the right environmental conditions. In these situations, an auto defrost feature can really help preserve your unit’s ability to operate reliably.

Much like in a freezer, an excessive amount of internal moisture can cause ice crystals to seed in unusual places, leading to a noticeable drop in efficiency. Dehumidifiers with a built-in auto defrost module prevent these ice crystals from propagating in the first place, thus making the unit safe to use in spaces with a sub-65° F average temperature.

Low Temperature Setting

As a supplement to the aforementioned auto defrost module, a dehumidifier with a wide range of low temperature settings can really come in handy if you intend to use your new unit in a frigid environment. In fact, these settings can typically allow a dehumidifier to safely operate in rooms that are colder than 41° F – below freezing, in other words.

The majority of dehumidifier users may not find these settings productive because they use their unit during the warmer, more environmentally humid months of the year. However, folks working in regions such as the Pacific Northwest, where the winter months come with an extra serving of humidity, will really relish the ability to relinquish humidity from their basement as the weather outside cools down.

Timer

The unfortunate truth is that many dehumidifiers produce a noticeable amount of noise while in operation. This can make it more challenging to use your unit, especially if needs to be placed in a part of your basement adjacent to a family members personal room or office. In these cases, a built-in dehumidifier timer can really come in handy.

Through programmable settings or an analog dial, these timers allow users to decide precisely when their unit will operate. This, in turn, may allow particular homeowners to set their dehumidifier in motion only when they are not present to hear it. These timers can also be useful for collecting ambient humidity only when a direct source of moisture (such as wet laundry) is present.

Factors to Consider before Purchasing a Basement Dehumidifier

There are numerous factors that you’ll need to take into consideration before purchasing a particular basement dehumidifier model.

That’s because the best dehumidifiers for basements, like all home appliance, as sized and equipped with features appropriate to their intended degree of regular use. This can make it very important to factor in details such as room size and average room temperature into your comparisons between top-performing dehumidifier units.

Furthermore, bigger does not necessarily mean better when it comes to dehumidifiers. While larger models typically include larger collection tanks, they also tend to be noticeably louder while in operation. Also, larger units may use more than one simultaneous method of collecting ambient moisture to increase efficiency.

In all, these are only a few of the considerations that you’ll need to address before finalizing your dehumidifier purchase. For more insights into the ways in which these details will affect your unit’s operation, consider speaking with your local handyperson or certified plumber.

Room Size and Average Humidity

Naturally, dehumidifiers are designed such that only a single unit is needed to eliminate moisture in a single room in your basement. However, your chosen model cannot accomplish this core task if it is underpowered or simply too low capacity to meet the demands of the room it is placed in. As such, it is always important to take into account your target room size before settling on a particular dehumidifier model.

In order to quantify a unit’s capability in this domain, you’ll first need to calculate your rooms size in square feet. This can be accomplished by multiplying its width by its length (including any unusual side rooms or outcroppings). Then, you’ll need to compare this sum to the average amount of moisture experienced in that particular room.

For example, a moderately damp area of less than 2,000 sq. ft. in size may only need a 25 pint dehumidifier. Conversely, a 3,500 sq. ft. space with regular floor sweat may need to opt for model with twice the dehumidifying capacity at 50 pints.

Noise Level

Due to their operational requirements, dehumidifier units can land on the noisy side of the home appliance spectrum. As a result, you should take time to consider where you intend to place your new unit and whether or not that location will be affected by the dehumidifier’s output noise.  If so, then your best bet would be to find a model that has been routinely described as quiet by its current users (as indicated in the product’s online reviews).

However, if you are unconcerned about noise emitting from your dehumidifier, then you can place this consideration to the side. Just keep in mind that a noisy dehumidifier can be a real bother if you end up needing to use your unit in a location other than your basement.

Room Temperature

Room temperature can come into play immediately when it comes to dehumidifier operation. Specifically, some units are only designed to operate efficiently within the average range of indoor temperatures. In almost all industry-standard model, this temperature range starts as low as 41° F and can top out as high as 95° F.

That being said, a room temperature within this range can still create problems for your dehumidifier (especially if you intend to use it continuously). Due to their cold internal compression units, dehumidifiers can begin to form internal ice at temperatures as low as 55° F. If you intend to use your dehumidifier in room at or around that temperature, then you’ll need to opt for a unit with low temperature settings that include an auto-defrost mechanism.

How a Dehumidifier Collects Water

Modern dehumidifier units collect ambient moisture from the space around them using either a refrigerant or desiccant method. Each of these methods come with varying extraction efficiency rates, not to mention a noticeably different internal operating temperature. 

As such, you should pay attention to the types offered at your preferred retailer to ensure that you are obtaining all the necessary features needed to efficiently dehumidify your basement.

how a regrigerant dehumidifier works

Refrigerant dehumidifiers are the most common overall and carry an average extraction efficiency rating. These units collect water by drawing humid air over a cold internal coil, causing the water to condense out and drop into the collection tank.

desiccant dehumidifier

Desiccant dehumidifiers, on the other hand, make use of an internal rotor covered in absorbent material (often made of silica gel) in order to directly capture ambient water vapor. 

These units have the added advantage of outputting dry air, thus encouraging drying in and around the moisture-afflicted space.

Read our in depth guide on how dehumidifiers work.

How Often You Will Need to Empty the Tank

For the most part, dehumidifiers operate independently without routine user interaction…with one key exception. Most dehumidifiers make use of an internal collection tank that must be occasionally emptied, which can become a chore of its own in basements with a steady volume of moisture. If you foresee this task becoming a problem for you, then it would be in your best interest to identify a dehumidifier model with as large a collection tank as possible.

Also, many dehumidifier listings include a specification describing the unit’s capacity. While this appears to reference the amount of water that the unit can hold (and thus, how often it will need to be emptied), capacity in this context actually refers to how much ambient moisture the unit can draw out of the air in a 24 hour period. All the same, this metric is still very important for gauging how capable a given unit be when it comes to keeping up with your basement’s dehumidifying needs.

What Size Dehumidifier Do You Need for Your Basement?

“Size”, when describing a dehumidifier, can describe both a unit’s physical dimensions as well as its capacity to extract a certain volume of humidity from the air in a 24 hour period. In the case of this second definition, precise dehumidifier size will depend primarily on the physical dimensions of your basement as well as the amount of moisture regularly trapped within that space.

For more information on how to properly size your dehumidifier, check out this helpful guide from the folks at Sylvane. However, regardless of the dehumidification needs of your basement, remember that you are always safe to use a “larger” model than your circumstances call for. In fact, larger and stronger dehumidifiers are often more able to tackle small jobs in a tighter time frame, often without the need to empty their larger containment tanks as often.

Do You Need a Basement Dehumidifier?

If you’ve found this guide, then chances are that you are looking at purchasing a dehumidifier for use in your home’s basement. Such a course of action, even as a preventative measure, can be beneficial to the well-being of your home’s residents. This is because excessive in-home moisture can allow mold and mildew to propagate (not to mention the risk for slippery floors where humidity is allowed to settle).

Despite these dangers, not every humid basement calls for a dehumidifier outright.

For example, a dehumidifier unit is best suited to homeowners who experience routine or ongoing moisture in one or more sections of their basement. This can range from slightly mugginess in the air to floor sweat to residual water left over from a major influx of water in the basement (such as after a flood).

If you are performing an in-home moisture test, you should be shooting for an RH (relative humidity) rating of 30% or lower in order to avoid the worst risks posed by basement moisture. Any amount over 50% is bound to cause problems though and should be addressed with a dehumidifier immediately. Any humidity response plan should additionally feature an attempt to resolve the source of the moisture (if possible).

If you really don’t want to spend the money on a humidifier right now, then there are ways you can get rid of humidity in your basement without one.

How Does a Dehumidifier Work?

As you well known, dehumidifiers basically operate by drawing humidity out of the air and converting it into a liquid form that can be disposed of. But not all dehumidifier units accomplish this task in the same manner or using the same mechanisms. In fact, modern dehumidifiers tend to use either a refrigerant or desiccant method of capturing excessive water vapor in their general vicinity.

As expected, these two methods differ both in terms of their core components as well as their flexibility when it comes to diverting water collected during their operation. Some details on the differences between these two types can be found above, in the “How the Unit Collects Water” subsection. Also, more detailed explanation of these key differences can be found here.

FAQ – Frequently Asked Questions about Basement Dehumidifiers

How do I clean my Dehumidifier?

Cleaning your dehumidifier need not be an onerous task, so long as you follow proper procedures and initiate a full unit cleaning on a regular basis. This is especially important because dehumidifiers are prone to encourage undesirable bacterial growth if they are not regularly sanitized.

To do this, first unplug your dehumidifier unit. Next, whip down your unit’s exterior with a damp cloth, making sure to apply slight pressure as you pass over any vents. With the exterior properly cleaned, you’ll next need to remove (and empty, if necessary) the reservoir tank. This tank should be cleaned both inside and out with a mild liquid soap.

While you have the soap solution available, remove and wash any air or water filters included in your unit. Once these components have all been rinsed and dried, they may be returned to the unit for regular use.

How Much Electricity Does a Dehumidifier Use?

Precise electrical demands will differ from one dehumidifier model to another. However, most dehumidifiers (like air conditioners) tend to require a greater level of energy consumption when they are working harder. 

As such, dehumidifiers (regardless of size) will consume more electricity if they are left on for a majority of the day or are persistently combating an ongoing influx of in-home moisture.

What Level Should I Set My Dehumidifier To?

Your dehumidifier settings come down to personal preference, especially when it comes to measuring your basement’s environment against the relative humidity standard (30%). In most cases, a dehumidifier’s default settings are fully capable of handling most jobs with relative ease and efficiency. 

However, if you are looking to save electricity or combat a larger influx of basement humidity, you may choose to lower or raise your unit’s settings accordingly

Where in My Basement Should I Place my Dehumidifier?

Dehumidifier placement is an important, but often overlooked, factor that can directly impact a unit’s ability to operate efficiently. As a rule of thumb, all dehumidifiers (regardless of size) should be placed six inches or further from a wall in order to promote intra-unit airflow. 

Also, your unit’s active face should be positioned towards the source of the humidity or, if the direct source is unclear, towards the broadest portion of the room.

How Long Should a Dehumidifier Run Per Day?

Most homeowners who are looking to combat moisture in their basement run their dehumidifiers for around 12 hours a day. 

In many cases, though, modern dehumidifiers are designed to startup automatically when they detect an abundance of moisture, making the act of continuous usage unnecessary.
