Best Dehumidifiers for Basements

Basements are notorious for being damp, musty, and prone to mold and mildew growth. This is due to the inherent nature of being situated below ground level, where moisture seeps in from the surrounding soil. Inadequate ventilation can compound the issue, making it essential to find solutions for preventing excess humidity in these spaces. Dehumidifiers serve as an effective tool in maintaining optimal humidity levels and ensuring a healthier environment in your basement.

A dehumidifier works by extracting moisture from the air and collecting it, either in a built-in reservoir or by draining it out via a hose. This process not only reduces humidity levels, but also inhibits the development of mold, mildew, and unpleasant odors. An added bonus is that a dehumidifier can help extend the life of your household items – such as furniture, documents, and electronics – that are stored in the basement.

When selecting the best dehumidifier for your basement, there are several critical factors to consider, including the size of the area to be dehumidified, the device’s capacity, energy efficiency, and any additional features that may be beneficial to your specific needs, such as an auto shut-off function or built-in pump system. Ensuring that the chosen dehumidifier effectively addresses your humidity issues in a cost-effective and efficient way is key to maintaining a healthy and comfortable basement environment.

With these factors in mind, we set out to find the top dehumidifiers for basements by thoroughly researching and evaluating numerous models. Our goal is to help you navigate the wide range of options and choose a dehumidifier that best suits your needs. So let’s dive in and explore the best dehumidifiers available for making your basement a drier, healthier space.

This is our largest, most capable model ideal for large rooms up to 4,500 square feet and/or very wet spaces.
  • Designed For Modern Home: That most dehumidifiers are clunky eyesores is news to nobody. We designed with the modern consumer in mind: a sleek clean look, convenient built-in wheels and handles, and a quiet fan that won’t drown out your current binge-watching obsession.
  • Super Easy To Use: Dehumidifiers don’t need to be complicated, so ours isn’t. Adjust to your ideal moisture setting, then let it run its continuous 24-hour cycle until the tank is full, at which point it will automatically shut-off. There’s also a drain hose outlet for continuous draining. The hose is not included; we recommend a ⅝” diameter garden hose with an internal threaded end, and optionally Teflon tape for extra security.
  • Eliminates Moisture Effectively: Our portable dehumidifier reduces moisture through its built-in pump compressor. It also features a Turbo mode that increases fan speed from Normal Air CFM 165 (cubic feet per minute) to High Air CFM 188 for maximum moisture removal.
  • Important Things To Know: Dehumidifiers emit heat when in use (that’s how they absorb the moisture). This product won’t work in the same room as an evaporative cooler, and is intended for any indoor space up to 4,500 square feet. It measures 15.4 x 11 x 24.3 inches, has a 1.6 gallon water tank capacity and removes up to 50 pints of moisture from the air per day.

The HOmeLabs 4500 Sq. Ft Energy Star Dehumidifier is a great investment for those in need of effective moisture removal in large rooms or basements.


  • Large coverage area of up to 4,500 square feet

We immediately noticed that this dehumidifier was easy to set up in our basement. Its large coverage area of up to 4,500 square feet and 1.6-gallon water tank capacity allowed us to effectively remove up to 50 pints of moisture per day (based on the 2012 DOE Standard). Besides, the built-in wheels and handles made it convenient to move around to different locations depending on our moisture needs.

The modern and sleek design of the HOmeLabs dehumidifier sets it apart from other bulky dehumidifiers. Additionally, the quiet fan did not interrupt our daily activities, making it a pleasant experience for us while it operated. The device was easy to use – we simply adjusted it to our desired moisture level, and it ran a continuous 24-hour cycle until the water tank was full. Once full, it automatically shut off, which we appreciated.

However, we noticed a few minor drawbacks with this dehumidifier. First, the hose for continuous draining was not included, so we had to acquire one separately. Also, if your indoor space has an evaporative cooler, this dehumidifier might not work efficiently in the same room. Lastly, depending on your area’s humidity, you may find yourself emptying the water tank quite often due to its capacity.

Overall, the HOmeLabs 4500 Sq. Ft Energy Star Dehumidifier is an excellent option for those looking to eliminate moisture in large rooms or basements. Its effective moisture removal, quiet operation, and user-friendly features make it a worthwhile investment.

Buying Guide

When looking for the best dehumidifiers for your basement, there are several factors to consider. These features can help you make an informed decision and ensure the best results.


The first thing to consider is capacity, which refers to the amount of moisture a dehumidifier can remove within a 24-hour period. Measure your basement’s square footage and find a dehumidifier rated for that space. Typical capacities range from 30, 50, to 70 pints per day. For larger basements, you may need multiple units or a whole-house dehumidifier.

Energy Efficiency

Energy efficiency is an important factor in choosing a dehumidifier that won’t break the bank with electricity bills. Look for Energy Star certified models, as they consume less energy while still providing excellent performance.

Dehumidifier SizeEnergy Cost Range / Year*
30 Pint$25 – $45
50 Pint$40 – $70
70 Pint$60 – $130

Note: The energy cost range varies depending on local energy prices and usage habits.

Humidity Controls

Look for dehumidifiers with adjustable humidity controls, which allow you to set your desired humidity level. Most models have a built-in hygrometer that measures the current humidity level and starts or stops the dehumidification process accordingly.

Drainage Options

There are three types of drainage options: manual, continuous, and pump-assisted. Manual drainage requires emptying the water collection bucket regularly, while continuous drainage allows for attachment to a hose that feeds water directly into a drain. Pump-assisted models use a built-in pump to push water up or out to a sink or drain, making them ideal for basements without a floor drain.

Noise Levels

Since dehumidifiers may be used in living areas, consider noise levels when making your decision. Most models have a noise rating in decibels (dB). Lower numbers indicate quieter units. On average, dehumidifiers produce noise in the range of 48-53 dB. Some models have multiple fan speeds, allowing you to choose a quieter setting when needed.

By considering these factors, you can choose the best dehumidifier for your basement, ensuring a comfortable and healthy living environment.

Frequently Asked Questions

What size dehumidifier do I need for my basement?

To determine the right size dehumidifier for your basement, you should consider the square footage and the dampness level. Generally, a larger dehumidifier is more effective in removing moisture. For a moderately damp basement up to 1,500 square feet, we recommend a 30-pint dehumidifier. For wet basements between 2,000 to 2,500 square feet, a 50-pint unit would be more appropriate.

Which dehumidifier brands are the most reliable?

Reliability is an essential factor when choosing a dehumidifier. Some of the most reliable brands we have identified are Frigidaire, hOmeLabs, Honeywell, and Keystone. These brands offer a good balance of quality, performance, and customer support.

Should I run my dehumidifier constantly?

Running your dehumidifier constantly is not always necessary, but it depends on the humidity levels in your basement. We recommend using a hygrometer to measure the humidity. If it consistently stays above 60%, you might want to run your dehumidifier regularly. Many modern dehumidifiers come with a built-in humidistat that allows them to automatically maintain the desired humidity level.

How often should I empty the dehumidifier?

The frequency of emptying your dehumidifier depends on its water tank capacity and the humidity level in your basement. Smaller units may need to be emptied every day, while larger units can go for a few days without needing to be emptied. Alternatively, you can use a continuous drainage option to avoid the hassle of manually emptying the water tank.

Which dehumidifiers are best for energy efficiency?

Energy efficiency should be a priority when selecting a basement dehumidifier. We recommend looking for units that are Energy Star certified, as these dehumidifiers use less energy and can save you money on utility bills. Top energy-efficient models include brands like hOmeLabs, Frigidaire, and Friedrich.

How do I maintain my basement dehumidifier for optimal performance?

Proper maintenance is vital for the long-term performance of your dehumidifier. We suggest the following steps:

  • Clean the air filter regularly, at least once a month.
  • Keep the water tank clean and free from bacteria buildup.
  • Inspect the unit for any blockages, dust, or debris around the intake and exhaust grilles.
  • Make sure the dehumidifier is placed on a level surface and has enough clearance around it for proper airflow.
