#1 Ivation Small Area Desiccant Dehumidifier

Ivation IVAGDM30

Ivation was the only dehumidifier manufacturer that managed to make our list twice. While neither of their systems uses a compressor, the Ivation IVADDH09 is the best quiet desiccant dehumidifier for small to medium spaces.

This dehumidifier is tall but thin with a depth of 8”. It has a streamlined design with a water bucket at the bottom and the controls at the top near a handle that flips up when needed. A digital display allows you to access all the functions on this machine or adjust the humidity in 5% increments to suit your needs.

The control panel provides access to the 12-hour timer and fans speeds as well. You can set the system to work in fan-only mode or turn on sleep mode to dim the display and drop down the speed. The system has three speeds and an operating range that puts other dehumidifiers to shame. The Ivation IVADDH09 will work in temperatures up to 104°F and is suitable for winter use until the temperature drops below 33°F.

Under optimum conditions, this dehumidifier is rated to remove 19 pints of moisture per day. There is an option for continuous drainage if you need to run it constantly, and a 0.75-gallon water bucket as well. Above the drain port on the back is a removable filter that’s washable and easy to clean. This dehumidifier has an anti-tilt shutoff for additional safety and a drying mode that works in conjunction with an adjustable air outlet.

As Ivation IVADDH09 desiccant dehumidifier, it is truly “whisper quiet” and a very efficient machine as well. It has more features that most quiet compressor-based dehumidifiers and the adjustable dryer vent is certainly a flagship feature. Pricing and size are potential drawbacks for this system depending on your needs, but it does not disappoint from a performance standpoint.

Pros: Quiet and efficient desiccant dehumidifier that can handle areas up to 450 square feet. Full range of features including an adjustable drying vent. Easy to use with multiple modes and speeds.

Cons: Nothing significant.

#2 LG PuriCare 50-pint Dehumidifier with Wi-Fi and Pump 

LG PuriCare UD501KOJ5

The LG PuriCare dehumidifiers are new, but arguably the most popular dehumidifiers in the past few years. While not exactly cheap, they provide a lot of bang for your buck. The LG PuriCare UD501KOJ5 is also very quiet for its size with a rating of 50 dB, considering it has a compressor and a built-in pump.

This sleek dehumidifier is safe and sturdy with a durable metal case and heat-resistant wire enclosures. There’s a safety standby mode that kicks in for an hour after 23 hours of runtime to prevent overheating, and a blockage alarm will alert you if the system becomes clogged. Other features include a 12-hour timer, automatic defrost control, automatic shutoff, and a notification system for the bucket.

Having a built-in pump is a huge advantage with any dehumidifier when continuous drainage is important, but the bucket should never be overlooked. LG has one of the better systems on the market with a side-loading 1.7-gallon water bucket that has a splash-free design. That’s something we’d like to see more of compared to traditional front-loading buckets, and homeowners found it easy to manage.

Wi-Fi is still considered a rare feature in the dehumidifier world, but LG included it on the UD501KOJ5. It’s not gimmicky like some systems as you can control the dehumidifier with your voice using Alexa or Google Assistant. You’ll also be able to use the LG SmartThinQ mobile app to manage your machine or get important information with a quick glance.

The LG PuriCare UD501KOJ5 won’t be for everyone, especially if you don’t need an internal pump. It’s an excellent high-capacity dehumidifier, however, and one that’s been very well received since it was launched. Unfortunately, this high-tech system only comes with a 1-year guarantee, so we recommend picking up an extended warranty.

Pros: Well-built dehumidifier with metal chassis and safety features. Voice control through Wi-Fi, a built-in pump, and 12-hour timer. Side-loading bucket with spill-proof design.

Cons: Short warranty for the price.

#3 Hisense Inverter Humidifier with built-in Pump

Hisense D10018TP1WG

While every dehumidifier we chose is quiet enough to let you sleep through the night, some are a little more silent than others. The Hisense DH10019TP1WG has the distinction of being the largest system on our list, but it’s also happens to be the quietest.

This full-featured dehumidifier has all the bells & whistles and is rated to remove 60 pints of water per day by current testing standards. It’s billed as an industrial-grade system, so it’s large and a bit bland, although there is a touch-based control panel across the top. From there, you’ll be able to access all the functions, including the internal pump.

The pump allows for continuous drainage, but there is a 2.5-gallon tank at the bottom of the unit as well. There’s a notification system for the bucket and filter on this dehumidifier, and it’s capable of operating at temperatures down to 38°F. It also has three speeds and four operating modes with manual, continuous, auto dry, and whisper-quiet.

On that note, this dehumidifier has a decibel rating of 36 dB on low, which is due in part to a high-performance centrifugal fan. The company also utilizes inverter technology on the Hisense DH10019TP1WG, which makes it up to 40% more efficient when compared to dehumidifiers of the same size. The dehumidifier is rated for areas up to 1,500 square feet and has a sturdy set of caster wheels to help you move it around.

It’s hard to go wrong with this dehumidifier if you need a system that can handle a large room. From the 24-timer to the multiple modes, there’s a lot to like and only one significant drawback. The Hisense DH10019TP1WG is sold as a Lowe’s exclusive, and while you can buy it online, it’s almost twice the price of similar systems. Their support has gotten mixed reviews as well, although you’ll get a 2-year guarantee with this dehumidifier.

Pros: High capacity system with internal pump, timer, and filter. Inverter technology makes it more efficient, and it has a decibel rating of only 36 dB on low.

Cons: The price tag.

#4 Ivation Medium Thermo-Electric Dehumidifier

Ivation IVADDH09

Peltier dehumidifiers aren’t as popular as systems with a compressor or even desiccant machines. They are one of the quietest types of dehumidifiers, however, and the IVAGDM30 from Ivation packs a punch for its size.

One of the drawbacks to thermo-electric dehumidifiers is the fact they are limited when it comes to capacity and coverage. While The IVAGDM30 can only hold 0.4 gallons of water, it’s still capable of handling areas up to 2,200 cubic feet under optimum conditions. The Peltier technology ensures quiet operation, and consumers found it simple to use.

Unfortunately, you’re not going to find many features on this dehumidifier. There are no timers, and you can’t adjust the output level, although it does have an automatic shutoff feature with an indicator light. The tank is removable as well, and the system has a capacity of around 16 ounces per day. It will leave a small footprint behind and tips the scales at 4.4 pounds unfilled.

If you’re interested in a quiet system and don’t care about features or the ability to adjust the settings, this dehumidifier is well worth a look. It’s efficient and reasonably priced for its size, but is light on features compared to other traditional dehumidifiers. You’ll also want to take the room rating lightly as this machine is best suited for small to medium rooms.  

Pros: Whisper-quiet system that’s easy to use. Removable 0.4-gallon water tank and automatic shutoff function.

Cons: Light on features.

#5 Ultra-Aire In-Wall Dehumidifier MD33

Ultra-Aire In-Wall Dehumidifier MD33

In-wall dehumidifiers are one of the newer trends in the industry and a unique way to remove humidity from your home discreetly. The MD33 from Sante Fe’s Ultra-Aire series is an ideal in-wall solution for medium rooms, and it’s quieter than a traditional system as well.

Because the Ultra-Aire MD33 is installed inside a wall, the noise level is reduced significantly. At full speed, this dehumidifier only produces 46 decibels, which is quieter than a compressor-based system and just a bit louder than Peltier and desiccant dehumidifiers. While this is a permanent solution that requires a space measuring at least 17.25”W x 6.75”D x 33”H, the MD33 is a very low maintenance machine.

This system has a moisture removal rate of around 33 PPD and is suited for rooms between 400 – 1,200 square feet in size. Other features of interest include a washable filter, auto-restart, and an automatic defrost. As this is a tankless dehumidifier, you will need access to a drain or holding tank but can opt for an external pump as well.

We didn’t find any significant complaints on this system, although the price is not for the faint of heart. The initial cost of this system is high, but it comes with a 4-year guarantee and has a galvanized steel cabinet that’s built to last. You will need to factor in the cost of a professional installation, however, unless you are very comfortable with wiring and tearing out a small section of wall in your home.    

Pros: Set and forget dehumidifier with a low profile that doesn’t take up any floor space. Low noise level, it’s well-built and has a 4-year warranty.

Cons: Initial cost. Professional installation may be required.

How to find a Quiet Dehumidifier

Finding a quiet dehumidifier is easier said than done, although hundreds of company’s claim to have nearly silent models. Well, in order to find the best quiet dehumidifier, you will need to dig deep if you don’t prefer one of the picks from our list. With that in mind, here are some tips to remember if you’re looking for a dehumidifier that won’t keep you awake at night.

The Sound of Silence

Noise levels are a funny thing. While there is a rating scale that gives folks an idea of what to expect in terms of noise levels, everyone’s hearing is different. A noise level that will be tolerable to some will drive others crazy, which is the first reason choosing a quiet dehumidifier is difficult.

Before we talk about decibel levels, it’s a good idea to understand what makes a dehumidifier quiet and where the noise comes from. In most cases, it’s because of the internal parts, but dehumidifier placement can have an obvious impact on the noise levels as well.

Types of Dehumidifiers

It may come as a surprise that there is more than one type of dehumidifier. Many homeowners hear the word and assume most systems are the same when that actually couldn’t be further from the truth.

  • Thermo-electric Dehumidifiers – A thermo-electric dehumidifier is one of the quieter models due to the lack of moving parts. These simple machines are referred to as Peltier dehumidifiers as well, and while quite effective, they are limited when it comes to capacity and features.
  • Desiccant Dehumidifiers – A desiccant dehumidifier is also extremely quiet. These systems use a desiccant rotor that recharges itself with heat. They can raise the temperature in a room or dry wet clothes, but are also limited from a size standpoint and can be more expensive compared to our next choice.
  • Compressor Dehumidifiers – This is the most popular style of dehumidifier and the tier where you’ll find more features like Wi-Fi or internal pumps. Unfortunately, they are the loudest style due to the number of parts involved, including the compressor. That said, you can find plenty of well-built dehumidifiers in this class with noise levels around 50 decibels.

While those are the three main styles, there are some hybrid systems to consider as well, along with whole-house dehumidifiers. Most of these dehumidifiers are a mixed bag when it comes to noise levels, but there are a handful of systems that use inverter technology or other techniques to bring the decibel levels down.  

Noise Levels

Noise levels are measured in decibels, which you’ll see listed as dB or dBA when browsing through dehumidifier specifications. While it’s an important number when you need a quiet machine, it’s something that only a handful of manufacturers provide. Even dehumidifiers billed as “quiet” only have decibel levels listed 50% of the time in our experience.

You can get a rough idea of how loud a dehumidifier is by comparing it against the table below. We’ve listed common noises that most people have experienced with a decibel rating to help you understand where most dehumidifiers measure up.

As you can see, dehumidifiers aren’t nearly as loud as a vacuum cleaner, and certainly won’t damage your eardrums as if you were standing near an ambulance siren. According to Yale, the level at which pain occurs from loud noises starts at around 125 dBA, but you can actually begin to lose or damage your hearing between 80-90 decibels with extended exposure.

Even some of the loudest dehumidifiers only come in at 50-60 dBA, so your hearing will be perfectly safe, even if they keep you up at night. It’s also important to understand that the ratings given by manufacturers are from dehumidifiers tested in a closed environment, and will differ from your home to a degree.

Capacity

Capacity can refer to many things depending on the device you are dealing with, but with dehumidifiers, it means how much moisture it can remove from an area within a set period of time. That can range anywhere from a few ounces a day to several gallons depending on the size of the dehumidifier. Your options are somewhat limited with quiet systems, however.

High-capacity dehumidifiers are larger and noisier than smaller machines, so if you want something quiet, it will usually be rated 50 pints per day or less. Dehumidifiers that size can cover a lot of ground, but you also need to be aware of recent changes to testing standards for dehumidifiers from the Department of Energy in the United States.

Capacity is measured in pints per day or PPD, and new standards have dehumidifiers tested at 65°F and 60% humidity. That’s a significant difference from the previous testing methods of 80°F and 60% humidity. Based on those changes, an older dehumidifier listed at 60 PPD would be 35 PPD by the new standards.

Coverage

While capacity tells you how much moisture a dehumidifier can remove, coverage refers to the size of a room or area. It’s a specification you’ll find on almost every machine, and it’s easy to understand as it’s measured in square feet. Small or personal dehumidifiers may use cubic feet, and several manufacturers use traditional room sizes as well.

When provided with two numbers, one is the average room size, and the other refers to tightly sealed environments under optimum conditions. The conditions in the area you’re trying to dehumidify can affect how well the machine performs, so it’s best to use the lower number or aim for somewhere in the middle.

Features

Whether you want a dehumidifier with an internal pump or one that you can control with your voice, there is an option out there for you. The nicer or more high-tech the feature, the more it will raise the price of the dehumidifier. Machines with Wi-Fi connectivity or internal pumps are two premium features to keep an eye out for, but there are also several common ones to be aware of.

Dehumidifiers with adjustable speeds are fairly common, although it’s rare to find any system with over three speeds. Washable filters and automatic shutoff can also be found on most dehumidifiers regardless of the style. Timers largely depend on the price of the system or manufacturer as some lines have them as standard.

Auto-restart can be hit or miss, but many medium to large dehumidifiers have alert systems for the bucket and timer. If you don’t look forward to dealing with buckets of water daily and have access to a drain, consider a dehumidifier that offers continuous drainage through a port instead of a pump.

Dehumidifier Warranties

If you’re looking for a dehumidifier with a long warranty, you’ll want to stick to certain brands. Most offer a simple 1-year guarantee, which can be disappointing given the cost of some dehumidifiers. A company known for producing well-built machines will provide you with some peace of mind, but it’s no replacement for long warranty or great customer service.

Extended warranty plans are offered through most online retailers, and are worth considering if you’re spending several hundred dollars on a dehumidifier. We also recommend looking into replacement parts. While that can be challenging, several of the top brands have them readily available through their own website or third-party sources. 

Quiet Dehumidifier FAQ

Q: Are dehumidifiers noisy?

A: On average, you can expect a dehumidifier to come at around 35 to 60 dB on the decibel rating scale. That’s about as loud as a general conversation but considerably quieter than a vacuum cleaner or lawnmower.

Q: Is an internal condensate pump worth the additional cost?

A: If you don’t like emptying buckets or need to run your dehumidifier continuously, they are definitely worth the cost.

Q: How much different a dehumidifier weigh?

A: It depends on the size and type of dehumidifier. Smaller portable systems can weigh between 12 – 20 pounds while machines larger than 40 PPD can tip the scales at over 50 pounds or more.

Q: Will a dehumidifier prevent mold and mildew?

A: Yes. The right-size dehumidifier can stop mold and mildew from spreading throughout your home by clearing up issues with excess humidity.
