Best Basement Dehumidifier Buying Guide

Best Basement Dehumidifier

Basement dehumidifiers are simply devices capable of reducing the humidity levels of your basement thereby leaving a more pleasant environment. Unlike humidifiers, dehumidifiers remove moisture from the air, preventing the unpleasantness that comes with damp air.

High humidity levels can be caused by some factors including several structural related factors like plumbing leaks, inactive exhaust fans and cracks in the foundation. Below is our comprehensive buying guide to picking the best dehumidifier for your basement. But before we move on the guide, check our top 5 basement dehumidifier picks. 

5 Best Basement Dehumidifiers

1. Frigidaire FFAD7033R1 Dehumidifier With Wi-fi Controls

Frigidaire FFAD7033R1 70-Pint Dehumidifier with Effortless Humidity Control

The Frigidaire FFAD7033R1 is large capacity dehumidifier removing about 70 pints of water from the air per day. This dehumidifier is the most recommended dehumidifier due to its high moisture removal. The FFAD7033R1 unlike its predecessor the FAD704DWD draws air through the back of the dehumidifier and exhausts air through the side, this results in the FFAD7033R1 been less noisy and more effective than the previous model.

The FFAD7033R1 has several key features which make it more durable and easier to use compared to the previous model. The FFAD7033R1 has a humidistat for adjusting humidity levels, a check filter light, a full tank alert system to remind you to empty the tank when it’s full, a removable and washable filter that prevents bacteria from being released into the air, and defrost mode that ensures frost does not build up on the evaporator coils.

One of the downsides of the FFAD7033R1 is its tank capacity. For such a dehumidifier with a high moisture removal rate, the tank capacity is quite small. its 13.1-pint bucket is much smaller than the FAD704DWD which features a 16.3-pint bucket, this means that you’ll be emptying the water tank more frequently, although it shouldn’t be a problem if you are draining the tank via its external drain.

Overall, FFAD7033R1 is one of the best 70-pint dehumidifiers in the market. The FFAD7033R1 is also durable due to the high-quality material used in manufacturing it, meaning you wouldn’t have to worry about it breakage or leakages during use.

  • Humidistat: Yes
  • Timer: Yes
  • Auto Restart: Yes
  • Continuous mode: Yes

2. hOmeLabs HME020031N Dehumidifier

HomeLabs HME020031N Dehumidifier

Covering a space of about 4000 sq ft, the hOmeLabs HME020031N is one of the most effective dehumidifiers and one of the best alternatives to the Frigidaire FFAD7033R1.

The HME020031N is large capacity dehumidifier ideal for large rooms and basement, the dehumidifier is also quite effective removing about 70 pints of water from the air per day although it is much slower than the Frigidaire FFAD7033R1.

The HME020031N has several key features including a 1.6-gallon water tank capacity, a humidistat that can be adjusted to the desired humidity level, auto start and auto off modes, an auto-defrost mode to automatically lower temperatures and a timer.

Compared to the FFAD7033R1 features 3 fan speeds for adjustability, the HME020031N has two fan speeds – normal and turbo – which features a continuous mode.

The HME020031N is more affordable than the Frigidaire FFAD7033R1 and the lower cost certainly means it is lower in quality. The HME020031N is not as durable as the FFAD7033R1 as certain parts of the dehumidifier are made with thin pieces of plastic which could crack or break when dropped or mishandled.

The HME020031N can be drained manually by removing the water tank and emptying the water (the dehumidifier should be turned off during this operation) or continuously through the standard hose connected to the back of the dehumidifier. The latter is more convenient and prevents condensate from collecting in the water tank.

A downside of the HME020031N is noise production; the HME020031N is a compressor dehumidifier. During use, you would hear the fan noise which is nothing much to worry about, but you will also hear a compressor buzzing noise. In the FFAD7033R1, you will only hear silent pleasant fan noise.

The Keystone KSTAD70B is another amazing 70-pint dehumidifier on our list and it is one of the most affordable and best alternatives to other 70 pint dehumidifiers like the hOmeLabs HME020031N and the Frigidaire FFAD7033R1. The KSTAD70B covers a room space for about 4500 sq ft which are 500 sq ft wider than the HME020031N, however, the KSTAD70B comes packed the features and functions you would find in other 70 pint dehumidifiers.

The KSTAD70B’s key features include an auto-restart that saves your settings during a power outage, an auto-defrost mode, automatic shutoff, a timer, a humidistat, a transparent water level indicator, and a full bucket alert. The KSTAD70B is also a super silent dehumidifier producing a noise level of about 56 dBA on high settings and 54 dBA on low settings making it a great choice for users who seek to use them in their bedrooms. However, some users have cited the KSTAD70B is could get a little noisy during use. It’s definitely nothing to worry about if you won’t have running all the time.

When it comes to performance, the KSTAD70B performs quite adequately depending on your humidity settings. Most user reviews on Amazon praised its high moisture removal rate which makes it a great choice considering its low price.

One of the downsides of the KSTAD70B is building quality. Durability is one of the main things to consider when settling for a dehumidifier and the KSTAD70B seems to be one of the bad choices, which might due to the low price attached to it. The KSTAD70B seems to have to been made with notably quite thin plastic compared to that used for some expensive models. We suggest you handle it with great care especially when handling the water tank.

Best Dehumidifier for Basement Buying Guide

Today, there are so many brands of dehumidifiers in the market offering different prices and features which could make it more difficult to decide on a particular dehumidifier model. Our buying guide will point you in the right direction as we list things you should look out for when picking a dehumidifier for your basement.

How Do Dehumidifiers Work

A dehumidifier works by moving air over refrigerated (condenser) coils through the aid of a fan. The movement pulls moisture from the air and drips it into a tank, and then the dried air is pushed into the basement. By continuously performing this action, the humidity level of the room is reduced to a healthier level. The dehumidifier’s operating system is simply the opposite of the operating system of a humidifier which sole purpose is to increase the humidity level of a room.

Signs You Need A Basement Dehumidifier

A humid basement is quite unpleasant and could lead to several health problems, trigger allergies, breed dust mites, mildew, and mold. Below, we have listed some signs you that signal the need for a basement dehumidifier.

Musty odor in the air

The first sign that would be easily noticeable is a musty odor in the air. This smell is caused by the presence of mold and mildew in the air. You can spot mold and mildew growing on the ceilings, walls or on items in your basement.

Condensation

Condensation is another noticeable sign of high humidity levels. You may notice a build up on the floors, windows, and walls. If the humidity levels are extremely high, you would notice the condensation forming puddles on surfaces. You can also notice condensation through as fog on the glass (if present) or on the walls.

High Humidity levels

Rather than waiting for the signs, you can simply get a hygrometer and measure the humidity of your basement. Humidity levels greater than 50 to 55% signal abnormally high levels of humidity, therefore you would need a dehumidifier.

Other signs of high humidity levels include; the presence of dust mites, visible rot, and decay (if you have wood stored in your basement), peeling or cracking paint etc. In some cases, you would find frost or ice build up on cold surfaces in the basement.

Dehumidifiers prevent the growth of mold and mildew and the action of condensation by removing the excess moisture in the air, thereby reducing the humidity levels.


Types of Dehumidifiers

There are two types of humidifiers and their working systems depend on the ambient temperature in your basement. Both types of dehumidifiers are effective in reducing humidity levels by warming the air they process.

Desiccant Dehumidifiers

Diagram of Desiccant Dehumidifier

Desiccant dehumidifiers are the perfect choice for basements colder than 500 F (100 C). This type of dehumidifiers removes moisture from the air by adsorption. Desiccant dehumidifiers consist of a desiccant which is a chemical that absorbs moisture, a large rotating drum which removes moisture from incoming air, a condenser which condenses warm moist air, a heater which reheats air, and a blower (fan) which ensures air circulates throughout the system (some models might have more than one blower)

Desiccant dehumidifiers are quite effective at removing exactly the amount of moisture during a period of time as stated by the manufacturer. However, this can only happen if you operate the dehumidifier according to the manufacturer’s instructions.

Compared to compressor dehumidifiers, desiccant dehumidifiers are quite efficient and can be operated in very cold temperatures (about 340 F). On the other hand, compressor dehumidifiers can’t go below temperatures of about 410 F.

Pros

  • Removes moisture consistently at both high and low temperatures
  • No frost build-up
  • Wider operating temperature range
  • Very quiet during operation

Cons

  • Reduced moisture removal rate compared to the compressor based dehumidifiers.
  • Gives out a pungent odor during operation

Compressor Dehumidifiers

Compressor Dehumidifiers working principles

Compressor dehumidifiers are more effective at removing moisture from the air than desiccant dehumidifiers and this might be due to the fact that they remove moisture from the air by condensation rather than adsorption.

This is the main reason why compressor dehumidifiers are highly recommended as they perform the sole purpose of a dehumidifier effectively.

Cons

  • Frost Build Up
  • Noisy operation due to the compressor and the fan in the dehumidifier


Water Removal

The moisture removal rate of a dehumidifier will depend on its room coverage. Dehumidifiers like the HME020031N which covers a space of 4000 sq ft are able to remove 70 pints of water a day and do this effectively. Small space dehumidifiers like the Pro Breeze FBA_PB-03-US remove about 1 pint a day which is effective enough as it covers a space of just 220 sq ft.

Many models also have two or three fan speeds which let you control the moisture removal rate. It is important to check if the moisture removal rate of a dehumidifier suits your need as the sole purpose of a dehumidifier is to extract moisture from the air.

Operating Temperature Range

Every dehumidifier operates a certain temperature range. For basements, it is important to get a dehumidifier that can operate at low temperatures.

Energy Consumption

Most dehumidifier brands claim that their models consume small amounts of energy thereby saving energy costs. The only way to find out for sure is to check user reviews and the energy star certification so you won’t buy a dehumidifier that would skyrocket your electricity bills. You can also check out the dehumidifiers we listed above as they among the most energy efficient dehumidifiers you can find in the market.

Cost

Dehumidifiers could cost less than $50 for those with small room coverage and above $150 for those covering more than 2000 sq ft. When settling for a model it is important to note that being expensive doesn’t necessarily make it a better choice although expensive models like the Frigidaire FFAD7033R1 are energy efficient, perform effectively and are durable.

Size

It’s quite obvious that you need to pick a properly sized dehumidifier that could fit into the available space. It is also imperative you get a dehumidifier with top extendable handles or caster wheels for mobility as some dehumidifiers with large room coverage can be quite heavy.

Noise

No one wants a dehumidifier that makes a loud buzzing sound during use so it’s best to test-run the dehumidifier before finalizing the purchase. However, if you are buying from Amazon it could be quite tricky and you have to depend on user reviews.

Fortunately, you can simply pick a dehumidifier from our 5 best dehumidifier list as they all operate quietly.

Tank Capacity

Dehumidifier tank size

A dehumidifier with a small water tank capacity can be quite annoying as you will be required to empty the tank frequently when it gets filled up. This is why it’s best to pick a dehumidifier with a large tank capacity or one which drains via an external drain. However, dehumidifiers with these features are quite expensive so you should be ready to spend a little bit more for convenience

Features

Some dehumidifiers come with some added features which make them much better and more convenient than other models. It is important to also check out for these features when settling for a model.

Built-in pump: Dehumidifiers that make use of built-in pumps are more convenient when it comes to draining the water tank. Compared to some dehumidifiers which require you to empty the tank yourself, built-in pumps drain the dehumidifiers continuously and simply require you to press the “pump” button on the dehumidifier to drain the tank.

However, if your dehumidifier does not have the built-in pump option it is possible to carry out pump drainage by simply purchasing a condensate pump and hosing.

Defrost mode: Defrost mode is a feature that prevents your dehumidifier’s compressor from freezing. It is important to consider this feature if you are looking to operate your dehumidifier at colder temperatures.

Humidistat: A humidistat allows you to automatically monitor and control the humidity level of the dehumidifier. Buying a dehumidifier with a humidistat allows you to choose the desired humidity level and the dehumidifier will automatically maintain it.

If you’re going for a dehumidifier that lacks this feature, then you would need to buy a hygrometer to measure the humidity level of your basement.

Auto shut off: The auto shut off feature is a very important feature in dehumidifiers which indicates that the water tank is full and requires draining. This is important if you are want to run your dehumidifier at night or while you’re away. However, most dehumidifier irrespective of the room coverage come with this feature.

Washable filters

Most dehumidifiers are fitted with filters to trap bacteria, mold, and mildew, so they won’t enter the air. It is important to buy a dehumidifier with washable and reusable filters to save cost on replacements. How often you wash the filters will depend on how you use the dehumidifier but generally, you should clean the filters about twice a month.

Final Notes

Above, we have listed our 5 best dehumidifiers for basement based their functions, moisture removal rate, and energy efficiency. We also considered reviews on Amazon and made sure we pick only the ones that had the highest positive ratings and reviews. You pick any models listed above based on your room size and give it a try.

My name is Ryan. I have had a hard time dealing with my allergies. Happily, I found that an air purifier was effective to ease my allergy symptoms. I spent a lot of time researching the best air purifier. I know how hard it can be to find the suitable one.

During the reading period, I also read a lot about humidifiers and dehumidifiers. I learned the mechanisms behind the technologies as well as the manufacturers and organizations within the industry.

I now feel convinced that I have built a guide that shows you all you need to know about air purifiers, humidifiers, and dehumidifiers. So I came up with the idea of creating this website.
