Buyer's Guide

Basement dehumidifiers help you breathe comfortably by getting excess moisture out of the air in the basement. Basements are often susceptible to high humidity levels because of their proximity to the soil. Unvented clothes dryers and washing machines are also causes of high basement humidity. The product review above has given you foreknowledge of the best basement dehumidifiers. This buying guide concisely details the specifics of basement dehumidifiers. The types of basement dehumidifiers, factors to consider before making a purchase, and frequently asked questions about basement dehumidifiers are discussed.

What are the Types of Dehumidifiers?

Dehumidifiers can be categorized based on their mechanism of removing moisture from the air. Based on this categorization, there are three types of dehumidifiers.

Compressor Dehumidifier

A compressor dehumidifier contains a refrigerated coil and uses the condensation process to remove water from the air. The dehumidifier passes air over the refrigerated coil; this causes the air’s moisture content to condense like droplets on a cold bottle. The droplets are then emptied into a tank for disposal.

Compressor dehumidifiers are the most popular dehumidifier; they work well in warm climates and have low energy consumption. A downside of compressor dehumidifiers is that they make a lot of noise and are quite heavy.

Desiccant Dehumidifier

Desiccant dehumidifiers use desiccant materials fixed around a wheel to rid the air of moisture. A blower blows damp air into the dehumidifier, where the desiccant wheel absorbs the moisture. The wheel is then heated so that the trapped moisture drips out into a water tank. The dehumidifier subsequently releases the air into the room as dry, dehumidified air.

Desiccant dehumidifiers have the advantage of being smaller and lighter than compressor dehumidifiers. Compared to compressor dehumidifiers, they are quieter. The downside of desiccant dehumidifiers is the cost. They are more expensive than compressor dehumidifiers.

Peltier dehumidifiers

Peltier dehumidifiers are named after a French physicist, Jean Charles Peltier; they are also known as thermo-electric dehumidifiers. Peltier dehumidifiers draw in moist air over a heated sink. The air condenses as it passes over the heated sink. The water released by the dehumidified air drips into a water tank before dry air is now released into the room. Peltier dehumidifiers are usually small and work best in small basements.

What are the Things to Consider Before Buying Basement Dehumidifiers?

Considering the different types of dehumidifiers available, choosing the best dehumidifier for basements could be tricky. Below are the major factors to consider before purchasing a basement dehumidifier.

Basement Size

The first factor to consider when buying a dehumidifier for basements is the size of the basement. If you have a large basement to dehumidify, you will need a dehumidifier with the capacity to handle such a large space. Also, if the basement is small, a dehumidifier with high capacity will be overkill.


Another thing to consider before buying a basement dehumidifier is the dehumidifier’s portability. A portable dehumidifier unit can be moved to different areas in the basement for more effectiveness – a flexibility that fixed dehumidifiers lack. Portable dehumidifiers have casters that make it easy to wheel them around the basement.


Dehumidifiers cleanse the air and make the basement more habitable. However, a downside of dehumidifiers is the noise they make, which could be quite discomforting. Therefore, you should consider the level of noise the dehumidifier makes before buying a dehumidifier for your basement.


The moisture that dehumidifiers absorb out of the air in your basement has to go somewhere. Usually, dehumidifiers come with a tank that collects the water. However, the unit shuts down once the tank is filled up. Emptying the tank regularly may be challenging for people with a tight schedule. Thus, the bigger the tank, the better for the user. Alternatively, some dehumidifiers allow you to attach a hose to the collection tank to empty the water into a floor drain.

Adjustable Humidistat

A dehumidifier with an adjustable humidistat gives you more control over the humidity level in the basement. It allows you to alter your humidity preference under different weather conditions.

Energy Efficiency

A major concern for users has been the cost of running a dehumidifier. With new models of dehumidifiers, this concern is gradually being laid to rest. It would be best if you were on the lookout for models that are energy efficient.

Extra Features

There are other extra features that are useful additions to a dehumidifier for basements. For example, a dehumidifier with the automatic shut-off feature will detect when the basement’s humidity level is ideal and shut off by itself. This feature helps to save running costs. Also, a dehumidifier with the auto-reset feature remembers your settings from previous use. This feature is helpful in the event of a power outage. These extra features make it easier to use basement dehumidifiers.

How Much do Basement Dehumidifiers Cost?

The price of dehumidifiers for basements ranges between $40 and $2500. Overall efficiency and availability of extra features affect the price. Basement dehumidifiers within the $200 and $1,000 range offer a balance between cost and efficiency.


Q: How long should you run a dehumidifier in the basement?
A: There are no strict rules as regards how long a basement dehumidifier should run. It depends on the dehumidifier’s capacity and how much moisture it has to get rid of.

Q: Where should the dehumidifier be placed in the basement?
A: The best place to place a basement dehumidifier is the area of the basement with the highest humidity level. If the humidity is evenly spread across the basement, the center of the basement will be a good place for it.

Q: Will a dehumidifier get rid of the basement smell?
A: Yes, a dehumidifier will get rid of the basement smell. A dehumidifier rids the basement of the rotting smell that accompanies mold and mildew.

Q: Will a dehumidifier kill mold in the basement?
A: The simple answer is no. A dehumidifier may not be able to kill existing mold, but it helps prevent the formation of new ones by reducing the humidity in the basement.
