Best Basement Dehumidifiers (2019)

Choosing the right dehumidifier for your basement is very important. Moisture problems in basements are not only annoying and uncomfortable, but can lead to significant health problems, causing mold to grow and structural damage to the home.

A basement dehumidifier is built to solve moisture issues in basements. It can be used to keep basement humidity levels below 50 percent, preventing mold and mildew growth (mold and mildew begin to grow at 60%), protecting indoor air quality and preventing damage.

But how do you know which one is the best basement dehumidifier?

There are hundreds of dehumidifier brands to choose from. Even if you narrow down to the popular ones like Aprilaire, hOmeLabs, Frigidaire, Danby, Honeywell, GE, LG, etc… how do you know which basement dehumidifier best suit your needs?

To help you pick the right one, we did the research for you and created a detailed comparison of the top basement dehumidifiers available on the market.

Here is a Summary of Our Key Findings:

  • The best basement dehumidifier for most people is a portable dehumidifier. A portable dehumidifier offers a great ability to control the humidity in one large, continuous area like a basement. It’s also easy to move around, easy to install, and much less expensive initially versus a ducted dehumidifier or whole-house dehumidifier.
  • A 70-pint dehumidifier with variable speeds and automatic humidistat is the best choice for the basement. This size of dehumidifier is ideal for medium to large basements, and can treat a wide range of humidity levels – from slightly damp to extremely wet.
  • Our top pick of the best dehumidifier for the basement is the Frigidaire FFAD7033R1 70 Pint Dehumidifier. This portable dehumidifier is solid, well-made machine that has a good warranty, it deals extremely well with moisture problems in the basement. It is also an energy-efficient and quiet dehumidifier.
  • A ducted/commercial dehumidifier, such as the AlorAir Sentinel HD55 or the Aprilaire 1830 Basement Pro Dehumidifier, is much more expensive on initial purchase versus a portable dehumidifier. But it turns out the most energy-efficient dehumidifier option. These basement dehumidifiers can be 2 to 4 times more efficiently and remove 50% more moisture compared to leading portable dehumidifiers.
  • Basement dehumidifiers are noisy machines. So if noise is a critical factor in your dehumidifier choice, you’ll want to consider a quiet basement dehumidifier. The quietest basement dehumidifier we’ve found is the Danby Energy Star 70-Pint Dehumidifier. This dehumidifier is very quiet with just about 50 decibels noise level.
  • A basement dehumidifier with built-in pump, such as this TOSOT 70 Pint Dehumidifier, is the easiest way to pump out the collected water out of the basement if your basement doesn’t have a sump pump or floor drain and you don’t have time to empty the drainage tank regularly.
  • The cost to run a basement dehumidifier can be as high as the cost to run a small portable AC unit. Energy Star certified dehumidifiers use about 30% less energy than conventional units. In the long run, that means a savings of hundreds of dollars over the life of the dehumidifier.
  • All dehumidifiers generate heat that can make the basement hotter. You can dehumidify your basement without heating the air by using the AlorAir Basement dehumidifier. It has an exhaust for hot air generated.
  • If you’d like to turn your basement dehumidifier on or off, change humidity levels, and get notified when the water bucket is full while you’re out of the house, we recommend the Frigidaire FGAC7044U1. This smart dehumidifier features WiFi connectivity that allows controlling your unit from anywhere at your convenience.

What To Look For When Buying A Basement Dehumidifier

Whichever dehumidifier you’re going to choose, keep in mind that basements of varying sizes and dampness levels may require different-sized dehumidifiers to work most efficiently.

If you want to get the best dehumidifier for your basement, these are the most important factors you’ll want to consider before you make a decision.

Consideration #1: What size basement dehumidifier do you need?

To choose the right size dehumidifier for your needs, you must understand:

  • A dehumidifier’s size is determined by its total capacity to remove moisture. Capacity refers to how many pints of water the basement dehumidifier is able to extract from the basement in a single day.
  • Most basement dehumidifiers capacity is measured in per square footage of the basement.

To find the best basement dehumidifier, you’ll also need to consider the condition of your basement.

  • If your basement is moderately damp (basement feels damp with musty odor, 50-70% humidity level), you can probably stick with the rated capacity for your square footage.
  • If your basement is very damp (basement feels wet, smells musty; damp spots appear on walls and floors, 70-85% humidity level), you’ll need to choose a unit with a little more capacity.
  • If your basement is extremely wet (basement feels extremely wet, smells musty; seepage appears on walls and floors; may have mold growth, 85-100% humidity level), you’ll definitely need a large capacity basement dehumidifier.

The following guide will help you choose the right size dehumidifier for your basement.

Conditions in Your Basement300 sq.ft.500 sq.ft.700 sq.ft.1000 sq.ft.>1,500 sq.ft.
Moderately Damp (50-70% humidity) 30 pint 40-45 pint 50 pint 60 pint 70+ pint
Very Damp (70-85% humidity) 40 pint 50 pint 60 pint 70 pint 70-90 pint
Extremely Wet (85-100% humidity) 40-45 pint 50-60 pint 60-70 pint 70+ pint 90+ pint

Consideration #2: Water Removal Options

If your basement is in a very damp or wet condition, your basement dehumidifier will collect a large amount of water, and you’ll need to empty the internal bucket regularly.

So before you select a basement dehumidifier, you will want to consider the two most common water removal options: built-in pump or gravity drain.

If you place your dehumidifier near a drain in your basement, then the most convenient option is a dehumidifier with a direct drain feature.

For basements that don’t have a floor drain or sump pump, a basement dehumidifier with built-in pump is the best option, as it allows to pump water several feet vertically out of the basement or into the sink.

If your basement dehumidifier doesn’t have an internal pump, and your basement doesn’t have a floor drain too, then it’s best to buy an external pump for your dehumidifier, such as this Little Giant Automatic Condensate Removal Pump.

By using this condensate pump you do not have to look for a basement dehumidifier with built-in pump. External condensate pumps are affordable and typically pump higher than internal pumps. Condensate pumps can also be used for air conditioning equipment, whole house humidifiers, condensing boilers and other equipment where an automatic drain pump is required.

Consideration #3: Important Features to Consider

To find the best dehumidifier for basement, don’t forget to look at these dehumidifier features:

  • Choose a basement dehumidifier with an auto humidistat – This allows the dehumidifier to automatically turn on and off depending on the level of humidity in the basement. This saves energy and keeps the basement dry.
  • A dehumidifier makes more noise than a floor fan. If noise is a critical factor in your choice, choose a quiet basement dehumidifier.
  • Most basement dehumidifiers are built with “Low-Temperature Setting” and “Auto-Defrost” which allow units to operate optimally even at low temperatures, but they are not equal. Most portable dehumidifiers are designed to work at the temperature as low as 41 degrees Fahrenheit (5 degrees Celsius), some models are designed to work at even lower temperatures. So if you want to dehumidify your basement during the cold winter and keep it from freezing, don’t forget to consider this feature.
  • Is the basement dehumidifier Energy Star rated? – We highly recommend you invest in an Energy Star certified dehumidifier because it consumes much less energy than a non Energy Star certified dehumidifier. This will keep your energy consumption for drying the basement low and affordable.
  • All basement dehumidifiers will heat the air. A portable dehumidifier generates heat when running, but it doesn’t have an exhaust hose for the heat generated. Choose the latest version of top basement dehumidifiers, they generate much less heat, as well as less noise.

And Don’t Forget These Features:

  • Washable Air Filter: A washable air filter helps remove dust and allergens from the air and helps keep the basement dehumidifier running efficiently.
  • 24-Hour On/Off Timer: This is an important feature when selecting a basement dehumidifier. It allows programming a shutoff time up to 24 hours in advance to conserve power and match the needs of your basement.
  • Automatic Restart on Power Failure: Your basement dehumidifier should have this feature. When a power failure occur, it will resume operating in your previously selected settings once power returns. This is a great feature for unattended basements!
  • Auto Shut Off when the water bucket is full: If you drain your basement dehumidifier manually by emptying the bucket, and doesn’t use continuous drain hose or pump, then Auto Shut Off is an important feature to look at. This feature will automatically shut off the dehumidifier when the water reservoir is full to protect from spills and overflows.

With these factors in mind, let’s take a look at the top 7 best dehumidifiers for the basement with our detailed reviews.

Below, we also have a quick comparison table and some charts for you to compare the performance of these top basement dehumidifiers. So you’ll see which is the most efficient basement dehumidifier, or which is the quietest basement dehumidifier in the market.

The Best Basement Dehumidifiers (with detailed reviews)

1. Frigidaire FFAD7033R1 70-Pint Dehumidifier

Best overall basement dehumidifier

See on Amazon

  • Capacity: 70 pints per day
  • Best for: medium to large basements up to 4,500 sq.ft., with temperature from 41°F
  • Top Features: 3 speeds (Low, Medium, Turbo), Energy Star rated, Adjustable Humidistat, 24-hour on/off timer, Automatic Defrost Control, Automatic Shutoff, Bucket Full Indicator, Casters, Continuous Run, LCD Display; Custom Humidity Level from 35% to 85%
  • Noise Level (High): 51 dB

The Frigidaire FFAD7033R1 is one of the quietest and most energy-efficient basement dehumidifiers in the market. And this unit our BEST PICK!

As one of the top-of-the-line dehumidifiers on the market, this unit operates quietly and efficiently, maintaining a healthy humidity level at budget-friendly operating costs.

It’s rated at 6.7 amps and 745 watts, but the cost to run this basement dehumidifier will actually depend on how humid of your basement is and where the humidity comes from.

We had it running for two weeks at 45% humidity level at the low setting. Our ‘Kill A Watt‘ energy usage meter shows it’s averaging about 400 watts per hour. If we had a basement with severe moisture problems then maybe it would run non stop which would be about 650 watts per hour.

Some folks say that they have been running the Frigidaire FFAD7033R1 almost 24/7, with a few hours break in between on less humid days, and it seems their electric bills have increased around $10 to $20 a month.

Not only an energy-efficient basement dehumidifier, the Frigidaire also comes with numerous features to maintain healthy humidity levels in your basement.

Effortless Humidity Control allows you to control the exact percentage of humidity in your room. A removable washable filter that reduces bacteria, room odors, and other airborne particles.

The SpaceWise portable design includes a top handle, integrated side handles and caster wheels making it easy to move around the basement. Digital display with electronic controls for your convenience. You can also choose from low, medium, or high to suit your comfort needs.

Frigidaire is one of the very few dehumidifier manufacturers to include a middle-speed option between low and turbo, which might be the best compromise between noise and performance.

Overall, the Frigidaire FFAD7033R1 is our top pick as the best dehumidifier for the basement. This unit is one of the quietest, most efficient, and fastest-working basement dehumidifiers you can get. It is sturdy in design with a nice strong handle on top, so it seems to last long.

While this model has a gravity-fed hose outlet that will work great with a floor drain, it’s available with a pump too – Frigidaire Model FFAP7033T1 70 Pint Dehumidifier.

2. hOmeLabs 4,500 Sq. Ft Dehumidifier

The best value basement dehumidifier

See on Amazon

  • Capacity: 50 pints (70 Pint 2012 DOE Standard) per day
  • Best for: Basements between 3,000 and 4,500 square feet, with temperature from 41°F to 95°F
  • Top Features: Touch Control Panel; Auto Restart, Auto Shut Off, Auto Defrost; Humidistat or Continuous Mode; 24-hour Timer; Custom Humidity Level from 35% to 85%
  • Noise Level (High): 53 dB

The hOmeLabs Energy Star Dehumidifier is one of the best selling basement dehumidifiers on Amazon, and it has more than 4,300 reviews at the moment and most are 4 and 5 star ratings. It seems Amazon’s buyers are genuinely happy with this dehumidifier.

The hOmeLabs Dehumidifier is specifically designed for basements and other large spaces that range in size from 3,000 square feet to 4,500 square feet. If your basement is smaller than the manufacturer’s recommendations, the only real issue with oversizing your dehumidifier is that it can make the surrounding air hotter. But it will take less time for the dehumidifier to dry up the basement to a comfortable humidity level.

This dehumidifier offers six different settings and a 24-hour timer. It has touch panel controls with auto shut-off, defrost, restart, and 2-speed setting (low and turbo mode). It doesn’t include sophisticated automatic modes like some of the competition, but it’s good at all the important tasks. The humidistat works as it should, cycling on and off as needed to keep room humidity stable.

Compared to the Frigidaire, the hOmeLabs dehumidifier is a bit louder and less energy efficient. But you won’t notice a significant increase in your electric bill.

In general, the hOmeLabs 70-Pint Dehumidifier is one of the best basement dehumidifiers. This model is much cheaper than our top pick and sometimes appears in flash sales.

The Frigidaire is unquestionably a better dehumidifier for your basement, but if you don’t care about the noise difference or slightly-better performance and efficiency, then the hOmeLabs is definitely a no-brainer.

3. Danby DDR070BDWDB 70-Pint Dehumidifier

Quietest Basement dehumidifier

See on Amazon

  • Capacity: 70 pints per day
  • Best for: Basements up to 4,500 square feet, with temperature from 41°F to 95°F
  • Top Features: Touch Control Panel; Automatic Restart on Power Failure, Auto Shut Off, Defrost; 2 speeds with Turbo Mode; Continuous Dehumidifying; 24-hour Timer; Custom Humidity Level
  • Noise Level (High): 50 dB

The Danby DDR070BDWDB is the quietest basement dehumidifier we’ve found. At its highest fan speed – Turbo Mode, this model has a noise level of 50 decibels, which is about as loud as a refrigerator. Operating at the lower speed it’s even much quieter, just as quiet as a tower fan that is enough for you to sleep next to at night while it’s running.

This dehumidifier removes 70 pints of excess moisture per day, and is designed for basements and spaces up to 4,500 square feet. It features “Smart Dehumidifying” technology that measures the basement humidity level and maintains it efficiently.

Smart Dehumidifying feature analyzes your basement’s ambient temperature and humidity and automatically programs the most optimal humidity level for your basement. This technology also chooses the most efficient fan speed to maintain the set humidity.

For even greater convenience, the Danby DDR070BDWDB 70-Pint Dehumidifier boasts a fully-loaded electronic control panel that has all the controls you need to tailor operation for your space. Electronic push-button controls help you set a humidity level, select Normal or Turbo fan speed, stay informed of current humidity conditions, and activate the 24-hour on/off timer.

If noise is a critical factor in your choice, then the Danby DDR070BDWDB is the best dehumidifier for your basement. Not only quiet, this unit is also energy efficient. It’s Energy Star certified dehumidifier and will cost very little.

4. TOSOT 70 Pint Dehumidifier with Internal Pump

Best basement dehumidifier with built-in Pump

See on Amazon

  • Capacity: 70 pints per day
  • Best for: Basements up to 4,500 square feet, with temperature from 41°F to 90°F
  • Top Features: Built-in pump, 3 Speeds, Adjustable Humidistat, Light-Touch Control panels, Automatic Defrost Control, Automatic Shutoff, Power Outage Restart, Bucket Full Indicator, Timer, Digital Display, Custom Humidity Level from 35% to 80%
  • Noise Level (High): 52 dB

This is a great dehumidifier option if your basement doesn’t have a floor drain.  This TOSOT 70 pint basement dehumidifier has a built-in pump so you can connect the drain hose to your unit to utilize the internal pump drainage mode. Water will still collect in the drain bucket, but once you activate the pump mode, this water will be pumped out as the bucket approaches maximum capacity.

With the addition of a built-in pump, you can drain water automatically using the included drainage hose in any direction, and up to 15 feet away from the dehumidifier. It’s also available with a gravity drain.

The TOSOT dehumidifier removes 70 pints of moisture per day, which is ideal for medium- to large-sized basements. Like Frigidaire dehumidifiers, TOSOT is one of the very few manufacturers to include a medium mode between low and turbo mode, which might be the best compromise between noise and performance.

On three speeds, the TOSOT basement dehumidifier all works very quietly. In fact, rated at 52 dB maximum, this is one of the quietest dehumidifiers for the basement on the market.

Quiet, Energy-Star rated, and well designed, the TOSOT is one of the best basement dehumidifiers you can buy. But it is expensive.

There is a lot of other basement dehumidifiers in the $150-$200 range that we looked at and we think they would have done a tolerable job. This TOSOT dehumidifier is another $80 – $100 above the normal range, but you could consider this a positive as well as a negative since it also has a powerful built-in pump and can dehumidify a very large basement.

5. Keystone KSTAD70C 70-Pint Dehumidifier

A compact basement dehumidifier with a great power

See on Amazon

  • Capacity: 70 pints per day
  • Best for: Basements from 1,200 to 4,500 square feet, with minimum operating temperature from 41°F
  • Top Features: Adjustable Humidistat, Auto Defrost, Auto Shut off, Auto Restart, Water Level Window, Continuous Run, LCD Display, Full Bucket Alert, 24-hour timer
  • Noise Level: 55 dB

Featuring a compact design, the Keystone KSTAD70C is the best dehumidifier for a messy basement with all of the stuff that you’ve stored.

This model combines power and energy efficiency to remove mold-inducing moisture from your basement. It removes up to 70 pints of moisture from the air per day and is designed for basements from 1,200 to 4,500 square feet. It removes a lot of moisture from the air, on rainy days it fills the bucket in just a few hours.

The Keystone KSTAD70C has all the standard features most basement dehumidifiers have. Electronic controls with LED Display and 24-hour timer, Auto-restart saves your settings during a power outage and auto shut off when the humidity has dropped below the set level, 2-speed settings include Normal, Turbo and Auto-Defrost, a removable, easy-cleaning dust filter, etc.

However, the Keystone KSTAD70C dehumidifier is rated at 55 dB noise level, which makes it the loudest basement dehumidifier in our line up. But it’s not noisy at all, in fact, it’s just as loud as average home noise.

6. FRIGIDAIRE FGAC7044U1 70-Pint Dehumidifier

Best smart dehumidifier for the basement with WiFi Controls

See on Amazon

  • Capacity: 70 pints per day
  • Best for: Basements from 1,500 to 4,500 square feet depending on the dampness level, with minimum operating temperature from 41°F
  • Top Features: Energy Star certified, WiFi Connectivity, Compatible with Amazon Alexa and Google Assistant, Electronic Controls, Anti-Microbial Filter, Effortless Humidity Control, Bucket Full Indication, Auto Shut Off, Timer
  • Noise Level: 53.4 dB

If you’d like to receive “full tank” and other notifications on your phone, or to adjust your dehumidifier and turn it on or off without going down to the basement, the FRIGIDAIRE FGAC7044U1 dehumidifier with wifi controls would be the best dehumidifier for your basement.

This model is an upgrade of the older Frigidaire FAD704DWD model, with additional Wi-Fi connectivity that works with Frigidaire’s app, Amazon Alexa and Google Assistant.

You can control your basement dehumidifier via an app called Frigidaire Smart Appliances app. The Frigidaire App provides you the convenience to remotely change humidity levels, turn the unit on or off, and get notified when the water bucket is full. This app also works with Frigidaire smart air conditioners.

As with all Frigidaire dehumidifiers, the FGAC7044U1 is a great energy-efficient and powerful dehumidifier for the basement. This model removes 70 pints of moisture per day and can cover a large basement from 1,500 to 4,500 square feet depending on the dampness level.

Of all basement dehumidifiers we reviewed, the FGAC7044U1 is one of the most powerful units. It seems to be powerful enough to keep even large, very wet basements at the 50 percent humidity level or below.

Overall if the WiFi feature is what you’re looking for, then the Frigidaire FGAC7044U1 is the best basement dehumidifier you can buy. In fact, there aren’t many smart dehumidifiers available.

We wish this smart dehumidifier has a built-in pump. Its WiFi feature works really well and easy to set up, but its functionality is very basic. There not much you can do with the app.

7. AlorAir Sentinel HD55 Basement Dehumidifier

The most effective and efficient dehumidifier for basement

See on Amazon

  • Capacity: 55 pints per day at AHAM condition (80°F-60%), 120 pints per day at saturation (90°F-90%)

  • You want a basement dehumidifier that can be remotely controlled
  • You want one of the smallest basement dehumidifiers that won’t occupy floor space in your basement.
  • You’re tired of buying a new portable dehumidifier each year or every few years. You want a basement dehumidifier that will last for many years before needing to be replaced.

If these are what you’re looking for, then AlorAir Sentinel HD55 dehumidifier is one of the best basement dehumidifiers for you. The AlorAir Sentinel HD55 dehumidifier is an effective solution to moisture problems in the basement. It can also be used in crawl spaces and other enclosures.

The AlorAir Sentinel HD55 is so energy efficient because it uses a specialized high efficiency rotary compressor that is engineered to improve efficiency and lower noise.

The specialized hydrophilic film makes water collected quickly and drop down in the water tank, refine adopts brass tube with wall thickness of 0.25mm, which improve refrigeration effect 30%. The red copper pipe with upgraded trapezoidal internal thread, increases 50% refrigerant contact surface and 50% heat transfer rate. Dehumidification rate rises more than 30%.

In fact, the AlorAir Sentinel HD55 is the most efficient basement dehumidifier in our list, with an energy factor up to 2.4 L/kWh while a room dehumidifier with an energy factor of 2 L/kWh is considered an energy-efficient model.

The operating current for the AlorAir Sentinel HD55 is 3.6 amps – which is about 400 watts on the highest setting. Compared to the Aprilaire 1830 Basement Pro – 6.3 Amps, and the Frigidaire FFAD7033R1 – 6.7 amps, this AlorAir dehumidifier is very energy efficient. In fact, the cost to operate this AlorAir dehumidifier can be just about 50% – 60% of the cost to operate a portable dehumidifier.

Another thing we love about the AlorAir Sentinel dehumidifier is that it has an exhaust for hot air generated. All dehumidifiers generate heat, so it’s a great solution to dehumidify your basement without heating the air.

Furthermore, you can place this unit anywhere, whether it’s an unfinished or finished basement, or a crawlspace as well as those places enclosed. The humidifier comes fitted with a remote humidistat, so you can control your basement humidity level from anywhere in your home.

The AlorAir Sentinel HD55 dehumidifier is a one-stop solution for controlling mold-causing humidity in your basement. This is a very effective and efficient basement dehumidifier that has the widest operating temperature range and humidity range of all basement dehumidifiers we’ve reviewed.

The fact that the AlorAir Sentinel HD55 is not the best basement dehumidifier for most people, it’s ideal for those who want to maintain the humidity level in true “set it and forget it” fashion. It’s the best dehumidifier for basements in low-temperature areas. It is also a high capacity basement dehumidifier designed for restoration purposes.

Basement Dehumidifier Comparison

Which is the best quiet dehumidifier for basements?

The quietest dehumidifier for basements we evaluated is the Danby DDR070BDWDB Dehumidifier. At its highest fan speed – Turbo Mode, this model has a noise level of 50 decibels, which is about as loud as a refrigerator.

The Frigidaire FFAD7033R1 is also a very quiet basement dehumidifier. It only reaches 51 decibels on its turbo mode, while many 30 pint models are rated at 52 to 54 decibels.

The loudest basement dehumidifier in our list is the Keystone KSTAD70C with the noise level of 55 decibels. But 55 dB is NOT noisy at all.

Normal conversation is typically rated at 60 decibels, the smallest window air conditioners emit 45 to 55 decibels, most bathroom exhaust fans emit 45 to 60 decibels. So, 55 dB is just as loud as the average noise in the home.

Which one is the most energy-efficient unit?

The benefits of energy-efficient basement dehumidifiers can help you maintain your basement’s humidity levels without inflating your energy bill.

The energy efficiency of dehumidifiers is measured by its energy factor, in liters of water removed per kilowatt-hour (kWh) of energy consumed or L/kWh. In general, a higher energy factor means a more efficient basement dehumidifier.

Most basement dehumidifiers we’ve mentioned above is Energy Star Certified. In order to be approved by ENERGY STAR, energy-efficient dehumidifiers must have an energy factor of at least 2.00, or an energy factor greater than 2.80 for dehumidifiers that remove more than 75 pints of moisture a day.

Dehumidifier’s rated amps and watts are also important to know the operating cost of your basement dehumidifier.

The AlorAir Sentinel HD55 dehumidifier has an energy factor of 2.4 L/kWh, and a rated current of 3.6 amps, is the most energy-efficient basement dehumidifier in our list.

Of all portable dehumidifiers for basements we evaluated, the Frigidaire FFAD7033R1 is the most energy-efficient unit. This basement dehumidifier has an energy factor of 2.0 L/kWh, and a rated current of 6.7 amps, which is equivalent to 740 watts. But in fact, the real power consumption is much lower than that.

We had it running for two weeks at 45% humidity level at the low setting. Our ‘Kill A Watt’ energy usage meter shows it’s averaging about 350 to 400 watts per hour. If we had a basement with severe moisture problems then maybe it would run non stop which would be about 650 watts.

In idle mode, with compressor off, the Frigidaire FFAD7033R1 draws only 0.4W to 0.5W. In comparison, the hOmeLabs 4,500 sq.ft dehumidifier draws about 1.1W at idle and it’s averaging about 420 watts to 440 watts per hour.

Generally, all the models we show you in this article are among the best energy-efficient dehumidifiers for the basement available. You will not be noticing anything significantly higher in your monthly electric bill.
