Buyers Guide & Information

Best Quiet Dehumidifier

The best quiet dehumidifier will be the one that you notice as little as possible and can keep the relative humidity nice and comfortable.

When shopping for a dehumidifier, it might seem like power and size are the two most important factors, but with something running as frequently as a dehumidifier, the noise created by the device is a crucial factor.

While often overlooked, we have reviewed eight of the highest performing dehumidifiers on the market today.

Why Dehumidifier Noise Matters

Bedrooms & Nurseries

Sleeping is one of the most important parts of life, and interruptions to sleep from loud noises can have lasting effects. This is doubly true for nurseries where children with more sensitive ears can be disrupted and have trouble getting back to sleep without parental assistance. These rooms will want dehumidifiers no louder than 30 dB, which is about the same level as a quiet street.

Small apartments

Apartment living has its share of special cases thanks to shared walls and size restrictions, so loud noises are an issue not just for you but neighbors as well. Add in that a smaller space naturally means you’ll be closer to the dehumidifier, and you will want to make sure you keep your options to around 48 dB or lower to keep the noise close to a conversation and avoid it interfering with others.

Lounge rooms

When you want to relax, a loud humming is not quite what most people picture, and typically in a lounge room, there are other more enjoyable audio sources to use. To avoid blowing out speakers to enjoy a movie or music, look for a dehumidifier no more than 50 dB that you can be somewhat distanced from.

Basements

Basements are often much more spacious, but such large areas also allow for easier echoing and noise amplification. If your basement is typically in use, something under 45 dB would be preferable, but for those who use it for storage or very little, going up to 50 dB range could be an option.

Buyer’s Guide to Choosing a Quality Quiet Dehumidifier

Noise Output Range

When considering a dehumidifier, it is important to note that the noise output range is different depending on the dehumidifier’s fan speed and any other settings that may impact it. On the low fan speed settings, you should look for something below 45 dB and high somewhere less than 50 dB.

Dehumidifier Type

There are three main types of dehumidifiers that are best suited for different rooms or environments.

  • Thermal Condensation
    Thermal Condensation dehumidifiers pull in air and pass it over cooled coils to cause condensation to develop and fall into a reservoir and pull it from the air. This is best suited for many rooms of the house like bedrooms, nurseries, or living rooms.
  • Absorption/desiccant dehumidification
    Typically single use, these types of humidifiers are placed in a smaller space and are made from materials that naturally draw in moisture like silica gel. These are best suited for closets or small enclosed spaces where a traditional dehumidifier may not fit.
  • Ionic Membrane Dehumidification
    Requiring little to no maintenance, the ionic membrane process may not have the highest efficiency in dehumidification, but they are the quietest since their process requires no liquid water. By using voltage at a molecular level, moisture is trapped within the system, and dry air is output. These are best in places where you may not easily be able to drain a more traditional dehumidifier.
Coverage Area

The general rule in coverage area is that the larger the space, the larger the dehumidifier. This is due to the need to be able to draw in the air effectively and recirculate the air once it has been processed. There are various sizes to meet nearly any home’s needs, and many are designed to cover the entire home.

Energy Efficiency

Dehumidifiers are typically quite consistently in use and have been made much more energy efficient in recent years. When shopping for an energy efficient dehumidifier, you look for things like the ENERGY STAR mark that denote that a device has met the qualifications as a high efficiency electronic device and has met certain governmental requirements to earn the title.

Water Tank Capacity

Depending on the environment you live in, the water tank may need to be cleaned out more often, and a larger water tank capacity is a better option. Those looking to set up a dehumidifier in a larger space may also want to look for something 30 pints or larger.

Ease of Use & Maintenance

Set up varies by design, but many dehumidifiers require minimal effort and often can be as simple as removing the packaging, inserting the water tank, and plugging in. Some feature digital controls that make use of a small touchscreen or buttons to navigate various settings or power on and off.

Maintenance on the units on our list is quite simple and generally requires just emptying the water tank when full and wiping it out to avoid any build-up.

Other Features
  • Drainage
    Some dehumidifiers have the option to automatically drain their water tanks through a hose that can be placed in a sink or near a drain for easy cleanup. It is important to note if the dehumidifier requires such a drainage system or allows for manually draining via removing the water tank.
  • Filter Indicator Light
    Dehumidifiers with filters that also help treat the air as they pull out moisture will often come equipped with a light that indicates the filter’s health and provides a warning when it must be replaced to continue to be effective.
  • Auto-Humidistat
    The humidistat is designed to work with your home’s heating and cooling and maintain a constant moisture level as set on the device. This allows for more flexibility, depending on the temperature.
  • 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 those who may lose power during a storm or while away that need to keep the dehumidifier running without being able to access it.
  • Low Temperature Settings
    Dehumidifiers with low temperature settings are designed to work below 65 degrees Fahrenheit and are ideal for colder climates to ensure the moisture collecting does not freeze.
  • Frost Sensor
    The frost sensor on a dehumidifier indicates when there has been a build-up of frozen moisture on the coils and alerts you to the need to remove the blockage. If not treated, blockages can cause the device to no longer function or cause unsafe drainage from the device.
  • Warranty
    As with all electronics, warranties vary by manufacturer, but you should look for a warranty covering replacement of parts that may fail or entire device coverage if available. As long as the damage is not caused by anything other than normal use, you can find plans to cover for multiple years.
Price

Dehumidifiers do not have to be expensive. However, it is good to consider investing in one that may be slightly higher in price as these devices are designed to last for years and run for long periods of time. You can certainly find a great dehumidifier on nearly any budget, and we have reviewed a few different price ranges below.

Noise Levels & Decibel Ratings Explained

The decibel scale is a logarithmic scale that compares the level of noise generated by a source compared to other noises. The CDC recommends keeping exposure to noise below 85 decibels.

The average conversation is about 60db, and whispers are around 30db. In comparison, something like a jackhammer is around 120db. Dehumidifiers tend to be in the 30-60db range depending on their size, how they are constructed, and any issues with internal components such as motors or compressors.

The device’s location can also impact it as uneven floors, concrete or carpet, and proximity to walls can influence how loud the noise from the dehumidifier is perceived.

Additional Tips to Reduce Dehumidifier Noise

In the previous section, we discussed location and maintenance as impacting dehumidifier noise. Here we’ll dive into methods of determining what may be causing an increase in noise.

Check the blower wheel and fan blades while the device is unplugged and, if possible, turn them. If you notice any noise coming simply from the parts moving without the motor, you will want to check if there are any obstructions and, if possible open the dehumidifier to see if anything is impeding connections between the blades/blower wheel and the motor.

If you do not hear any noise while doing this check, plug the dehumidifier back in and see if the noise persists and if so, you may need to check the compressor. This may mean the compressor is nearing the end of its lifespan and needs to be replaced.

People Also Ask (FAQ)

What humidity level should a dehumidifier be set at?

Like SleepFoundation.org, many organizations suggest around 60% humidity for internal relative humidity levels and not to go below 30-40%.

Can I leave a dehumidifier on overnight?

Yes, though you will want to check the tank’s water level if it is not set up to drain automatically.

Where should I place a dehumidifier for quietest operation?

Consider a corner that is farthest from any space used for activity and leave space between the dehumidifier and the wall.

How do I clean and take care of these devices?

You should inspect the water tank every day or every other day to avoid standing water. For filters, refer to the product manual though generally, it is best to clean reusable filters once a week to once a month.

Where is a good place to buy these units?

Amazon and Sylvane are fantastic online resources to find a quiet dehumidifier. If you would like to shop in store, Home Depot, Lowes, and other home improvement stores carry a variety of quiet dehumidifiers.

Conclusion

The best quiet dehumidifier will be the one that you notice as little as possible and can keep the relative humidity nice and comfortable without breaking the budget.
