Basements Dehumidifier Buying Guide

Reducing basement humidity is difficult. Knowing when you’ve got it under control is hard until a big storm hits and adds water.

You can buy a dehumidifier. Dehumidifiers come in many sizes and typically work best within certain conditions to maximize their effectiveness. For instance, depending on the room size and cold, you may need one for your basement or crawlspace.

The following guide will inform you of things to remember when purchasing a basement dehumidifier. It would help if you familiarized yourself with these characteristics before shopping online.

Factors to Consider

When you’re buying a dehumidifier, there are many different factors that you need to think about.

That’s because the best dehumidifier sizes are considered by the appliances used in different areas of the house. It is important to consider the room size and average room temperature when choosing between top-performing units.

Additionally, the size of a dehumidifier does not always correspond with how much moisture it collects.

These are only a few details you will need to consider before purchasing a dehumidifier. For more insights into how these details will affect your unit’s operation, speak with a handyman or plumber in your area.

Room Size

Dehumidifiers are designed to be used in only one room. Still, because they’re often too small for the space, it’s important to consider the dimensions of your desired area before purchasing.

To get an approximation of the square footage covered by your furnishings, measure the width and length of each wall. If any room has a different shape or size than others, include its measurements separately in this calculation.

Use this number to calculate how much moisture is present on average: divide the total square feet (measured above) by 50. 

For example, a moderately damp area of 2000 sq. ft may only need to be dehumidified with 25 pints. On the other hand, average square footage of 3,500 sq. ft., with floor sweat, will need a 50-pint capacity dehumidifier.

Room Temperature and Average Humidity

If your basement is designed to be a cozy living space or even a spare bedroom, the temperature will most likely not fluctuate as much. Extra insulation paired with an efficient heating system and effective window seals will make the air temperature steadier. You should not need to worry about dehumidifier freezing in these conditions.

However, if your basement is not energy-efficient or adequately insulated, there’s a chance that the frosty winter temperatures will affect even the best dehumidifiers for basements. In this case, it’s crucial to use a device with auto-defrost and low-temperature settings so that your basement can still be kept dry without taking a toll on your wallet.


Dehumidifiers for basements can have ducting, allowing them to heat more than one space at a time. It also makes it possible to tuck the dehumidifier away discreetly in a closet or other area so that it doesn’t infringe on your living space. Remote controls, humidistats, and timers add to the functions available on a basement dehumidifier.


A high-capacity dehumidifier can work for light use if you don’t plan on living or entertaining in a space. For dense carpeting with fewer higher-pile areas, it’s best to opt for a dehumidifier that emits less noise and is unobtrusive.

Important Features

Now, let’s explore the features a high-quality basement dehumidifier should have. To select your final product, you will need at least a few of these features if you plan to use the unit for an extended time. Most of these features affect performance and are important considerations when selecting a new device.

Hose Drain Outlet (Drainage)

Consider a model with a hose and drainage solution if you use your dehumidifier for an extended period. The drain outlet will prevent you from having to empty the condensation tank.

Installing this type of hose drain allows you to use gravity drainage to remove moisture from dehumidifiers instead of spending time emptying them.


Many modern best dehumidifiers are fitted with an auto-humidistat. This valuable energy-saving feature causes the dehumidifier to shut off when optimum moisture levels are reached. It closely monitors moisture levels and will start back up again if humidity levels begin to rise.

Condensate Pump

Basements with uncommon areas of high humidity have to run condensate pump systems to keep the moisture content at reasonable levels. Condensate pumps use downward pressure, created by a dehumidifier, to move the water it collects off-site into collection points like floor drains.

If your basement needs an additional condensate pump, you might need to do some research. Quality dehumidifiers can come with a built-in condensate pump, allowing for more flexibility over the unit’s lifespan.

Auto Defrost

Dehumidifiers built to work in basements often rely on cold condensation units. To avoid a potential issue with freezing, be sure to purchase an auto-defrosting feature for your dehumidifier.

Dehumidifiers with a built-in auto defrost mechanism eliminate the need for deactivating (defrosting) them after use, which means their efficiency is increased.

Low-Temperature Setting

These can prevent the dehumidifier from frosting or freezing over in temperatures as low as 41 degrees Fahrenheit. This can allow continuous use throughout the seasons. It also lowers the risk of potential damage from ice and frost.


Dehumidifiers make noise, and some people might not like that. It can be hard to use because it is close to someone else’s office or basement.

A built-in dehumidifier timer can help with this problem by automatically turning off the unit when the dehumidifier is operated. This is helpful for those who want the unit to run only when they are not present at home because they may hear it, and it also collects ambient humidity in an area where there is a direct source of moisture, such as wet basement laundry.

Home Local Climate

The local climate type is a huge factor for a consumer to consider when looking at basement dehumidifiers. Will it have to work all year in a high-humidity climate, or will it need to cope with freezing temperatures in winter and high humidity levels in summer? 

Features such as Low-Temperature Settings and Auto-Defrost can be invaluable in areas with colder winter climates. Drainage options will depend on the climate too. 

Climates that are warm and humid all year may benefit from a floor drain outlet to avoid frequent emptying from almost constant use. In contrast, climates that experience freezing winters may be better suited to an internal pump as it will be less exposed to freezing temperatures.

There are various other features a consumer can keep a close eye on when choosing a basement dehumidifier. They may not affect the efficiency of the dehumidifier itself. They can, however, make your life a bit easier and help to keep the dehumidifier running smoothly.

Filter Indicator Light

A clogged air filter can reduce the efficiency of a dehumidifier. If a filter is allowed to become blocked completely, it may stop the system from working altogether. A filter indicator light can be convenient to let you know when the filter is close to needing a change. This can save an expensive call-out, a repair fee, and downtime from an ineffective dehumidifier.


This is a handy feature. In the event of a power outage, your dehumidifier will reset automatically to its previous settings when it restarts.

Compressor vs Desiccant

Compressor dehumidifiers are the most common and use a refrigeration cycle to capture moisture from the air by removing heat. Because of this, they do not work as well in basements where temperatures fluctuate widely due to the coldness of the basement floor and the surrounding walls. Desiccant dehumidifiers use an adsorption cycle, capturing moisture from the air by removing water vapor. Thus they can work in basements and other places where temperatures are more consistent.


Where should I place it?

If you have a basement, it’s a good idea to place your dehumidifier in the room that receives the most water and foot traffic – this will help cut down on the amount of time needed to run your dehumidifier.

What Size Do I Need?

If you have a 500-square-foot basement with medium humidity (70%-80%), you need at least a 50-pint dehumidifier.

Should I Get an Oversized Unit?

An oversized basement dehumidifier could seem expensive, but it has the potential to save you a lot of money in the long run.

A small-capacity dehumidifier will not be adequate for large rooms like basements and is more likely to break prematurely.

Will this Product Reduce Humidity Upstairs?

Yes, there is often a connection from the basement to the upstairs of most houses. Humidity from the basement can seep through and cause dampness on other floors, but dehumidifiers in your basement will keep humidity levels low and avoid this problem.

Is It Possible to Dehumidify the sub-floors and the Rest of the House With One Whole Unit?

Yes, installing a whole-house dehumidifier in the basement can help with moisture problems throughout your house.

How to Measure the Humidity in a Sub-basement?

  • Buy a hygrometer. With this device, you’ll instantly find out the humidity level in your basement.
  • You can also test the humidity in your basement by taping a piece of aluminum foil to the wall. Return later and compare it to another untouched strip.

How Necessary Is this Unit?

A dehumidifier will keep the air in a basement or crawl space dry, which keeps it from absorbing excess moisture and resulting in musty odors. This helps maintain the area’s ideal indoor relative humidity (RH) level.

Will a Sub-level Unit Help an Air Conditioner?

Yes, a basement dehumidifier makes the air better. It cleans and filters the air, controls moisture, and reduces odors. Running a dehumidifier in your air-conditioned home will reduce your energy usage. This is because it makes removing moisture from the air easier for your air conditioner to work more efficiently.
