Dehumidifiers help me to manage the high humidity in my home, but I also have two young kids, and the last thing I need is a noisy dehumidifier waking them up all the time.

That's when I started researching which dehumidifiers were the quietest.  

In this guide, I'll share what I've found and introduce you to the best high performing, but near silent, dehumidifiers on the market.

These will help you keep the humidity and noise levels to a minimum so you can have a comfortable home without any disruption.

The Britsou PD11D is best for those looking for a fast unit that covers a large area.

Pros
  • Near silent running 
  • Large coverage
  • Fast, with good energy efficiency
  • Portable
  • Several different settings
CONS
  • Small water tank size
  • Not as long lasting as other models

Need to reduce your indoor humidity fast?

You don't need a big, noisy, commercial model, you can do it with the whisper quiet Britsou PD11D!

I use this model in my home and it's one of the best quiet dehumidifiers around for removing moisture quickly without you even noticing it's there.

It's got loads of positive reviews and it's my top pick for anyone who wants a dehumidifier with low noise output. 

The Britsou dehumidifier is compact, but with a large area coverage. It has 3 settings to suit your conditions:

  • DEHU mode to maintain the humidity in living spaces 
  • DRY mode will help to dry out your clothes
  • CONT mode to manage very high humidity environments

It's the CONT mode which impressed me the most, and just how quickly it pulled moisture out of the air.

A lot of portable models can struggle with humidity levels above 80%, but when I used this in my garage it reduced the moisture levels to under 50% in 12 hours.

I was equally impressed with the energy efficiency of this 50 pint unit. It has accurate sensors to assess the humidity levels exactly so it only turns on as needed. This saves a lot of power and means it makes even less noise overall.

Plus, this small, lightweight unit can be moved easily. I mostly used it in one area where the humidity in my home was highest, but you can move it around your home or store it when it's not in use. 

The only slightly annoying thing about the Britsou dehumidifier was how often it had to be emptied.

It removes moisture quickly, which is great, but the tank size is so small that you can end up emptying it twice a day. It does come with a fixed drain option and I'd recommend using this so it can drain automatically. 

This is one of the best quiet dehumidifiers for those with high humidity year round. It's energy efficient, fast acting, and has very little compressor noise output.

This makes it a real asset for those who want to feel the benefit of a dehumidifier without even noticing it's there.

The Bublue DH1 covers a large area and also has air purification capability. It is great for those who want to maintain healthy air quality.

Pros
  • Great for large areas
  • Very quiet
  • Built in filters for air purification
  • Suitable for continuous operation
CONS
  • Poor quality drain hose
  • Only a 1 year warranty

A large space needs a more powerful dehumidifier, but that doesn't mean it needs to be loud.

The Bublue is one of the best quiet dehumidifiers for larger living areas and will let you control the humidity without raising the noise levels.

This powerful dehumidifier has a variety of settings so it can handle different humidity levels around your home.

If it's running at full capacity it can remove up to 25 pints of moisture from the air in 24 hours, which is good for a portable unit.

It's also designed for continuous running, and has an auto shut off feature when the tank is full. All of this makes the Bublue dehumidifier perfect for humid rooms that have a lot of moisture. 

I mostly used the Bublue in my garage to manage the moist conditions, but it can be moved between rooms too. It's lightweight (provided you empty the tank), and has wheels on the bottom so it can be pulled without lifting.

What I really liked about this dehumidifier was how much space it could cover effectively.

It can handle a much bigger area than your standard portable dehumidifier and the control panel display screen actually showed me how fast the humidity levels were dropping.

I also really appreciated the built in air filters which purify the air while it's being dehumidified. 

Despite the appliance having more filters I didn't notice any extra compressor noise output. 

The only criticism I had for this dehumidifier was the tank size and I had to empty it frequently to keep it running.

It does come with a connected drain option, but the drainage hose that comes with it is quite poor quality.

I'd recommend buying a separate garden hose attachment to prevent any leaking. 

Despite some minor issues with the hose, this dehumidifier is great for large living spaces. It can cover a big area without the high noise levels you might expect, and it will protect larger homes without you even hearing it running.

The Simsen CT-2 is an excellent option for those looking for removing moisture from a small room.

Pros
  • Super quiet
  • Large water tank so it can run all night
  • Low energy
  • Won't overdry the air
CONS
  • Only suitable for small rooms
  • Fewer running options/settings

High humidity can negatively impact the quality of your sleep, but a loud dehumidifier can stop you from getting to sleep in the first place!

The Simsen CT2 will help to protect you from moisture without raising the noise levels, letting you breathe clearly and giving you a good nights sleep.

This compact dehumidifier is easy to set up and use. There's just one cable and several light up buttons on the control panel to choose the most appropriate setting.

You haven't got as many different fan speed or running options as other models, but for bedroom dehumidification you don't really need them. 

The design is minimalistic and it will sit unnoticeably in most rooms. This, combined with the fact that it's so quiet, means that you probably won't even notice it running.  

What I really like about this dehumidifier is how low maintenance it is.

For a small dehumidifier it has a large tank size, which means it can run all night without needing to be emptied.

It's also very energy efficient. and can remove a several pints of moisture without drawing much electricity. 

The drawback of this dehumidifier is that it will only operate in small rooms and hasn't got the power to deal with very high humidity.

However, in most bedrooms you don't need that much power and it means there's no risk of overdrying the air and disrupting your sleep. 

This dehumidifier isn't suitable for managing the humidity levels in a very humid garage or basement, but it's perfect for bedrooms.

It will keep you comfortable without creating much noise output, and at this price it offers some amazing value too.

The Tenergy Sorbi is best for those looking for a small and compact model that they can move around.

Pros
  • Compact and lightweight
  • Exceptionally quiet
  • Air purifier and dehumidifier in one
  • Simple to use
CONS
  • Only suitable for small rooms
  • Only 2 settings - low and high

Space is always at a premium in your home and if you're trying to manage the humidity in a small room or office then you don't want the dehumidifier to take up lots of space.

The Tenergy Sorbi is so compact it can fit anywhere, plus it has basically no noise output so it won't disturb you. 

The Tenergy Sorbi dehumidifier is lightweight, but long lasting. It only weighs 7 pounds and can be picked up and moved easily.

It also has a 5 foot cable so in most small rooms you can position it anywhere and still reach an electrical outlet. 

It also draws very little power, which is good for anyone who wants dehumidification 24/7 without spending a fortune.

You will have to empty it frequently and replace the filters every 3-6 months, but it should give continuous protection from humidity.

What I like most about this dehumidifier is that it also purifies the air. It has a built-in HEPA filter which removes over 99.7% of harmful contaminants from the air supply.

This can improve your health and wellbeing and prevent asthma or allergy triggers. 

The only limitation of the Tenergy dehumidifier is the power output. It removes a lot less humidity than larger dehumidifiers and it isn't suitable for larger spaces or very humid conditions. 

However, if you've got a small study, office, bedroom, or living room that would benefit from dehumidification and air purification then it's a great choice.

It's so small you won't see it, and the noise levels are so low you won't hear it, improving your air quality without any hassle.

The HOmeLabs HME020030N is a powerful option for using it in damp and wet basements. It is also suitable for larger rooms and spaces.

Pros
  • Manages high humidity levels easily
  • Very quiet running
  • Several modes for more effective dehumidification
  • Works in cold conditions
CONS
  • Not portable
  • Hard to empty the tank - better with the continuous drain option

Basements generally have high humidity levels so basement dehumidifiers need to be more powerful.

The HOmeLabs HME020030N dehumidifier has enough power to protect your basement, but runs quietly enough that the noise levels won't disturb you.

This makes it perfect for anyone with a small home, or a basement that's used as a living space. This powerful dehumidifier has enough coverage to deal with even the most humid conditions.

I've used it in basements with over 85% humidity and it's managed to get them to under 55% overnight, so it's definitely capable of reducing humidity levels quickly.

Other then the power and the low noise levels, there are two things I really like about this quiet basement dehumidifier - the turbo mode and the defrost function.

The turbo mode gives the dehumidifier an extra boost so it can remove more moisture.

My basement tends to have higher humidity levels when it rains so the boost mode made it easier to manage the moisture and protect my home. 

The defrost setting helps to protect the dehumidifier. Most refrigerant dehumidifiers can't handle cold temperatures, so they can struggle in a cold basement.

However, the defrost setting thaws out the coils inside to protect the dehumidifier and keep it running properly.  This keeps it running properly and helps to protect the dehumidifier from any ice damage.

One of the limitations of this quiet dehumidifier is that it is isn't very portable. It's also quite difficult to empty the tank.

It's much easier if it's installed in one place and connected to your plumbing with the continuous drain option.

This dehumidifier is powerful enough to protect your home from water damage and damp, but quiet enough that the noise levels won't disturb you.

If you live in a humid area and want a quiet dehumidifier to use year round then this is the one for you.

The Afloia Q10 is prefect for small spaces like RV campers that require both dehumidification and air purification.

Pros
  • Built-in air purifier
  • Whisper quiet
  • Compact, lightweight and portable
  • 3 stage timer and 3 fan speed options
CONS
  • Low airflow and only useful for smaller spaces
  • Small tank size

RVs and campers can often have high humidity levels, but loud dehumidifiers just won't work in the small space.

The Afloia Q10 is the perfect dehumidifier for RVs and campers because it's compact, simple, effective, and there's basically no compressor noise output. 

This dehumidifier is specifically designed for small spaces. It will only remove a relatively small amount of moisture compared to other models, but that's all you need to manage the relative humidity level in a limited area.

The device itself is light too (just 6 pounds), so you can pick it up and move it as needed. 

What I really liked about these quiet dehumidifiers is that they purify the air. The built in HEPA filter will remove 99.97% of contaminants, so you can manage the humidity level and breathe cleaner air.

This is particularly useful in a camper or RV because there is often a lot of dust, pollen, pet dander, and smoke pollution in the air. 

I also appreciated the easy to use control panel and different speed settings.

Most small dehumidifiers have limited programmable options but the Afloia Q10 has 3 fan speed settings and various timer options.

This means you can program it to run while you're out and about. 

The only drawback with this small dehumidifier is the limited air flow. It does have a built in pump to remove moisture from the air, but the fan is small so it won't really work in anything more than 150-200 square feet.

You may need to use an air conditioning or fan system to encourage airflow into the dehumidifier for the best results. 

That being said, if you want a compact, effective, and whisper quiet dehumidifier in a small room, RV, or camper, then this is one to look at.

The Afloia Q10 will lower the humidity level and improve your air quality without you even hearing it's running.

The TOSOT 50 Pint is excellent for large areas that require continuous draining of moisture.

Pros
  • Powerful - can manage high humidity in large spaces
  • Accurate humidity measurement and controls
  • Well made and durable
  • Auto restart feature for continuous protection 
  • 3 drainage options
CONS
  • Higher energy draw
  • Not portable

Tired of having to constantly empty your dehumidifier manually? Then you need a dehumidifier with a drain hose attachment.

The TOSOT dehumidifier is one of the quiet dehumidifiers you can connect right into your plumbing so you can run it with very little maintenance.

This makes it the perfect quiet dehumidifier for areas which need continuous dehumidification. This 50 pint dehumidifier is made for tough jobs.

It has a built-in pump that can handle a lot of moisture for a big area and when I used it in a very humid garage it was able to reduce the relative humidity level to under 50% in just a few hours. 

It's also a very accurate. There's a humidistat connected into the dehumidifier which gives a reading of the relative humidity. 

This allows you to program the device to reach and stay within certain humidity levels.

This feature is common in modern dehumidifiers, but this is one of the most accurate humidistats I've seen. 

What I really like about this 50 pint dehumidifier is the overall quality. It's made with good quality materials and even the garden hose attachment is durable too.

It has several safety features and will even auto restart after a power outage. This means you can safely leave it running in a humid room with confidence that it will protect your home without causing any issues. 

The only downside I found with this 50 pint unit was the energy consumption.

This dehumidifier does remove a lot of moisture but it also draws a lot of power, It isn't enough to put me off the device, but you should be prepared to pay a bit more to run this appliance. 

Overall, this is one of the best dehumidifiers for continuous operation. The TOSOT 50 pint dehumidifier gives you a lot of power with very little noise output, and it's perfect for those with larger homes that have high humidity.

The Shinco SDZ1-70P/P is great if you want quick drainage of collected moisture from anywhere with the help of a built-in pump.

Pros
  • Very large coverage
  • 3 drainage options
  • Powerful but quiet pump
  • Various programmable settings and speeds
CONS
  • Prone to leaking
  • Shorter lifespan than competitor brands

Dehumidifier pumps let you get drain water quickly from your home. The only issue is that dehumidifier pumps can be loud.

Shinco have solved this problem and with their quiet, but effective, dehumidifier that's great for anyone who needs continuous dehumidification. 

This 70 pint unit is designed for large spaces which have a lot of moisture. It can work in areas with a relative humidity of over 80% and reduce it to under 40% in just 24 hours.

There are 3 different speed settings and a 24-hour programmable timer so you can use it exactly as needed.

The control panel is straight forward to use and I didn't need the instruction manual at all to program it.There's even a child lock to stop the youngsters from interfering with the controls when it's set. 

What I like most about the Shinco dehumidifier is the drainage options. There's a 24 inch hose for auto drainage into a floor drain, or an 80 inch hose for pump drainage.

The built-in pump is much more powerful than other home dehumidifiers too, and it is able to push water against gravity and out of your home.

The one issue I found with the Shinco dehumidifier is that it can leak. If this happens you'll need to double check all the attachments and make sure it's all secure. Some people have also reported issues with the drain hose.

I thought the quality was reasonable, but you may need to replace it if there's water leaking. 

Shinco have proved that a dehumidifier with a pump doesn't have to be noisy or disruptive. 

This model makes it easy to dehumidify big spaces and remove the water without any hassle, letting you protect your home effortlessly.

The ALORAIR Sentinal HD55 is powerful commercial grade dehumidifier with quietest operation. It is suitable for very large basement and crawl spaces.

Pros
  • Deals with lots of moisture
  • Protected from frost and corrosion
  • Quiet running
  • Low maintenance
CONS
  • Slightly inaccurate sensors
  • Filter can become loose and rattle

When you say 'commercial dehumidifier' you immediately imagine a large, rumbling machine that makes a ton of noise.

Thankfully, that isn't always the case and the ALORAIR Sentinal offers commercial grade dehumidification with very little noise output.

The Sentinal range have been designed specifically for very humid crawl spaces and basements. The dehumidifiers have a compact design, but they're extremely powerful and capable of removing over 120 pints of moisture a day!

To put that in perspective, your average residential dehumidifier won't manage more than 30 pints of moisture in a 24 hour period. 

It's built with all the features to keep it running constantly too.

There's a humidity sensor which lets you program the humidity level between 30-90%, an auto restart feature in case of a power outage, and an auto defrost function so it can work in low temperatures. 

What I really like about this dehumidifier is the MERV-8 air filter. This filter removes some contaminants from the air, but more importantly it protects the internal mechanism from rust and corrosion.

This is great if you're leaving the dehumidifier in moist/humid conditions for long periods of time, and extends the lifespan of the product. 

One thing I did find slightly frustrating with this model was that the humidity sensor wasn't the most accurate.

It wasn't a huge problem because it was only off by a few % points, but it does make it harder to exactly manage the relative humdity. 

It's rare to find a dehumidifier with so much raw power giving off so little noise. If you have a very humid basement or crawl space then this is the perfect solution.

It's designed to be installed and left running with virtually no maintenance, so you just need to make sure you don't forget it's there!

What To Look For When Buying A Quiet Dehumidifier

Noise Level If You Are Sensitive To It

If you want quiet dehumidifiers then you need to check the noise output. I usually look for this on the packaging or specifications, but you can also contact the manufacturer to find the noise level of the dehumidifier.

The noise level is measured in decibels (dBs) and the lower the decibels, the less noise it will produce. The noise output of a dehumidifier will be influenced by the tank size, compressor noise, and fan speed options.

Ideally, you should look for quiet dehumidifiers with a decibel rating of under 45 dB.

Larger dehumidifiers will be louder, but all the models on our list are under 50 dB. 

TL;DR: You should look for dehumidifiers with a decibel rating of under 45 dB if you are particularly sensitive to noise. 45 dB is louder than a whisper but quieter than a normal conversation.

Purpose & Coverage Area

How and where you want to use your dehumidifier will influence which one you choose and the dehumidifier I use in my basement is completely different to the one I use in my bedroom.

The bigger the area and the more humid the space is, the more powerful the dehumidifier needs to be.

I would recommend measuring the area of the room and the current humidity levels.

You can then check the square feet coverage of the dehumidifier and the pints per day (PPD) rating to make sure it's suitable to the task.

The PPD is how much moisture the dehumidifier can remove in a 24 hour period so the more humid the space is, the higher the PPD rating needs to be.

Generally, smaller dehumidifiers will cover smaller spaces and won't be able to handle as much moisture.

For moist and humid rooms like basements, garages, and crawl spaces you will need a larger dehumidifier. 

TL;DR: The larger the coverage area and the higher the average humidity levels, the more powerful a dehumidifier you need. The dehumidification capacity of dehumidifiers is rated in terms of Pints Per Day (PPD).

A Larger Tank Capacity Recommended

The tank capacity of your dehumidifier influences how often it needs to be emptied.

In small spaces with limited humidity a small tank size is fine, but in larger rooms with more humidity you'll need to find a dehumidifier with a larger tank.

A 50 pint dehumidifier is generally the largest tank size of residential dehumidifier and that's what I use in my garage and basement, but there are a few larger units.

If you need continuous dehumidification and don't want to empty the tank then I would recommend looking at other drainage options. 

TL;DR: The larger the collection tank, the less often it will need to be emptied. A larger tank is recommended for saving you from the hassle of frequent emptying.

Drainage Type - Manual or Automatic

Dehumidifiers can be emptied manually, or connected to your drainage system so the water is pumped out automatically.

Manual emptying is best for those who want a portable dehumidifier as there's no fixed connections or plumbing. This allows you to move it between rooms, or into storage when it's not in use.

However, it does require you to empty the tank to keep it running and I usually have to empty my dehumidifier every few days.

Automatic draining is best for those who are running their dehumidifier constantly to manage higher humidity levels.

This allows your dehumidifier to run without stopping and means you don't need to manually empty the tank every day.

ACLAB Note:

Auto draining is either done through gravity draining whereby the gravity takes care of clearing the water from the unit or through pumps. These pumps are either built-into certain models or they can be bought and installed separately on the outlet of a dehumidifier.

Automatic draining isn't possible with all dehumidifiers so you'll need to find a compatible model with a pump and drain hose.  

TL;DR: Manual draining refers to emptying the collection tank yourself. Automatic draining is recommended if your dehumidifier runs constantly and if the moisture level in the space is always high.

Energy Efficiency/Certifications

A dehumidifier has a running cost between $0.03 and $0.16 an hour on average. 

The exact cost will vary depending on how energy efficient your dehumidifier is, but investing in a unit with higher energy efficiency can save you a lot of money. 

Look for a dehumidifier with an Energy Star rating. This means that the device has been certified as more efficient, and on average this means they will take 15% less energy to run.

This may not seem like much, but by selecting energy efficient models I've been able to save hundreds of dollars every year.

You can do the same, and if you're running a dehumidifier 24/7 then you should definitely look for an Energy Star rating. 

TL;DR: Always look for energy-efficient models as they can help save up on the running cost.

Cost To Procure and Your Overall Budget

Dehumidifiers can cost anywhere from $100-$2000, it all depends on what you buy.

Larger dehumidifiers, like whole house humidifiers, cost a lot more, but it can also vary depending on the quality and features of the appliance. 

All of the dehumidifiers reviewed here offer some great value for money, but it depends on your specific needs.

Look for a dehumidifier that can handle the square footage and humidity levels in the space adequately, but avoid getting models which are too big. This should balance performance with cost.

Good quality residential dehumidifiers will last around 5 years, but some cheaper models won't even last 2 years.

I would recommend spending a bit more on a better quality dehumidifier with a good warranty to protect your investment in the long term. 

TL;DR: Dehumidifiers can get expensive particularly depending upon their capacity. Look for models that best suit for your coverage area; neither too large nor too small to get the best value.

Extra Features

  • Filter Indicator Light
    Dehumidifier lights make it easier to maintain the unit by clearly showing when the device needs to be emptied or cleaned. This is a really useful feature for portable dehumidifiers which are emptied manually. 
  • Auto-Humidistat
    This is one of the features I always look for in a dehumidifier. A humidistat measures the relative humidity in the room and allows you to programme the dehumidifier to bring the humidity down to the right level. This maximizes the efficiency of the dehumidifier and helps to keep you in the most comfortable conditions. 
  • Auto Reset
    Auto Reset (or Auto Restart) is a feature that will power the device back on after a set period of time after a power failure. This is important for homeowners who need constant dehumidification and don't want a power outage to stop the dehumidifier from running. 
  • Frost Sensor/Auto Defrost
    Cold conditions can damage the dehumidifier coils. A frost sensor or auto defrost function will either indicate you need to clean ice from the coils, or will remove the ice automatically. This will help to keep your device running and increase the overall lifespan of the dehumidifier. 
  • Warranty
    Dehumidifiers should last 5-10 years and you should always look for a warranty to protect your investment. Ideally, your warranty should be 2 years or more. 
  • Programmable Timer
    Dehumidifiers generally need to run for 12-24 hours to have an impact. A programmable timer will let you set it to run for as long as needed before it turns off. This helps you protect your home from high humidity without overinflating your electricity bills.
  • Different Run Settings
    Some dehumidifiers come with different fan speed and run settings, like laundry mode or DRY mode. These help you get the most from the dehumidifier and can be useful if you use the dehumidifier in different places or for different jobs within your home. 
  • Air Purification
    If you want to improve the quality of the air as well as remove the moisture then it's worth looking for a dehumidifier air purifier combo. These dehumidifiers have built in air filters to remove airborne contaminants and leave you with purer, healthier air. This is usually cheaper than buying and running a separate air purifier.

TL;DR: There are many additional features you can find on dehumidifiers. These add to the overall cost of the unit, but some of them like an Auto-Humidistat and Auto-Defrost can be essential to you.

Noise Levels & Decibel Ratings Explained

Decibels (dB) are the measurement of how much noise is created.

The quietest sound we can hear is 0 dB, which is near silence, and it goes up from there. The higher the decial rating, the louder a noise is.

The decibel scale is a logarithmic scale. This means that a 10 dB sound is 10 times louder than 0 dB, and 20 dB is 100 times louder than 0 dB. Here are some example decibel ratings below to give you an idea of how loud things are:

  • 10 dB is the sound of normal breathing
  • 30 dB is the sound of a whisper
  • 60 dB is the sound of a normal conversation
  • 95 dB is the sound of a motorcycle 
  • 120 dB is the equivalent of standing beside of near sirens

It's important to understand the relative noise levels to protect you ears.

Listening to noise above 70 dB for an extended period of time can damage your hearing, and loud noise above 120 dB can cause immediate harm to your hearing [1].

Your average dehumidifier is generally in the 30-60 dB range. The exact decibels will vary depending on their size, how they're made, and what internal components they have.

The location of the dehumidifier can also have an impact, and if it's placed on an uneven floor or near walls it can change the noise level. 

A dehumidifier generally won't be loud enough to damage your hearing, but it can be disruptive. 

Looking for dehumidifiers with a dB rating below 45 is best to avoid noisy disruption in your home, but the quieter the better.

TL;DR: An average dehumidifier runs in the range of 30-60 dB. This isn't loud enough to cause hearing damage, but those on the louder end of the spectrum can be disruptive. Hence we recommend dB range of less than 45 for comfort.


FAQs
