9 Best Dehumidifiers For Basement Use


For those of us that have basements and crawlspaces in our homes we have to worry about conditions that create a habitat for mold, mildew and bacteria. And when there’s mold and bacteria, there’s problems for those with allergies and asthma. Fortunately, the best dehumidifier for basement use can easily handle and control this problem.

Though a decent size investment, the cost of running a dehumidifier seems rather small in comparison to the full blown reconstruction you may need when you’ve got serious moisture problems. Mold remediation can cost anywhere from $500 to $30,000 to fix!


Mold & Mildew Protection

As previously mentioned, mold and mildew is a common predator in dark and musky locations like your basement, crawlspace or attic. These dehumidifiers are the perfect solution to control even the largest basement areas.


Accurate Humidity Controls

You get to control exactly the settings you want and need. These units are powerful and operate at the parameters that you require.

Water Damage Be Gone

Normally, excess humidity can cause a lot of damage to tools, equipment, photos and other items that you store in your basement. Pulling this excess water out of the environment will protect the integrity of your belongings and prolong their life expectancy.


There are varying types of dehumidifiers on the market and choosing one is normally fairly easy. Simply determine what kind of operational demands and features you need and pull the trigger. Here are a few of the primary things you’ll want to consider.

Check Room Size

Check Pints

Check ENERGY STAR  Qualified

Check Continuous Draining System

Check Auto Defrost to prevent coils from freezing


Without a doubt, the first thing you need to determine is how big of an area do you need to control. After you’ve determined the size of your basement (or control area), you can choose the corresponding dehumidifiers Pint capacity – how many pints/hour or day does this thing pull?

More options include whether or not you want to manually drain your dehumidifier or go with the Continuous Drainage feature, which allows you to hook a hose up to the unit and connect it directly to a drain or sink. No more emptying buckets once a day? Yes, please.

Many people also find that a dehumidifier runs the risk of having their coils freeze up, perhaps due to the low ambient temperatures normally present in basement conditions. Fortunately, many units come with an Auto Defrost feature to combat this.

Lastly, running a large dehumidifier for extended periods of time can be a costly endeavor. One of the best ways to minimize your impact is to look for a unit that is ENERGY STAR qualified. Many of them are also compatible with your home’s smart thermostat.


Running large pieces of equipment not only costs money but sometimes come with consumer concerns and product malfunctions. Owning a dehumidifier – with all it’s internal components – oftentimes can prove to have its own issues. Below are some of the common issues that customers have with these types of units.

  • Frequent emptying of buckets
  • Units can give off extra heat in the rooms they operate
  • Evaporator coils freeze up due to low refrigerant, cold outdoor temperatures or a failing compressor
  • Continuous running fan makes for increased noise levels


Optimal Settings

Even the best dehumidifier for your basement can only do so much. Especially if you put it in a place where it can’t perform at its best or you set it to the incorrect settings for your space. Above you’ll find a chat setting where others just like you discuss their preferred settings. Most suggest under 60 RH.

Dehumidifier Maintenance

If you want to keep your dehumidifier running smoothly for as long as possible you will want to perform routine maintenance. Just like a portable AC unit, a dehumidifier will only last so long if it is not properly taken care of. Here are some tips on how to maintain and even fix some of the components on your own.
