The household we live in produces lots and lots of moisture by washing, exercising, bathing, cooking and even breathing. While a certain amount of moisture is important to the existence of a perfect environment, extensive moisture levels can cause us a lot of problems.Excessive humidity in your house makes the environment inhospitable. It not only makes allergy seasons harder for you but the damp conditions facilitate mold growth. The best course of action if you are living in a humid home is to get a good dehumidifier. Majority of the dehumidifiers people are usually familiar with are designed for compressor-based models.But if you have been spending some time on the internet, you might also have heard about desiccant dehumidifiers.

Why Get a Desiccant Dehumidifier instead of a Compressor-Based Dehumidifier?

Desiccant dehumidifiers are usually weaker in comparison to the typical compressor-based dehumidifiers when it comes to drying rates. But at the same time, these devices can be a great option in certain situations.

Keeping in view their smaller size, desiccant dehumidifiers are a good fit in smaller spaces, such as closets, bathrooms, and kitchens. Moreover, they are much quieter in comparison to compressor-based models. So if you get annoyed by high noise levels, desiccant dehumidifiers might serve you well.

If you like your environment green and healthy, a desiccant dehumidifier might be the answer to your concerns since it does not use any harmful refrigerants used in compressor-based models.

The best desiccant dehumidifiers are extremely effective at lower temperatures. They not only deliver better functionality but also aid in warming up the overall environment.

Keeping in view the above-mentioned facts, desiccant dehumidifiers may serve you well by bringing a big improvement in your lifestyle. Before you buy a dehumidifier, it is strongly recommended to consider your circumstances and specific purposes to make the best-suited choice.

How to Determine the Right Capacity of The Dehumidifier You Need?

Now that you know what is the right pint capacity of the dehumidifier you are going to purchase, you can consider having a look at our reviews of other dehumidifiers depending on your requirements. In this article, we will be only reviewing the top 10 desiccant dehumidifiers:

Types of the Desiccant Dehumidifier

Desiccant dehumidifiers are available in 4 different types –

1. Disposable desiccant dehumidifiers:

Disposable desiccant dehumidifiers are also known as moisture absorbers. These are low budget disposable dehumidifiers and may be used only once. Moisture absorbers have a low moisture sucking capacity per day and are effective in small rooms only. These properties make these products ideal for rooms where there’s no need for regular dehumidification.

2. Rechargeable desiccant dehumidifiers:

Just like moisture absorbers, rechargeable desiccant dehumidifiers are available at low rates and are small in size. They also have a low capacity for moisture removal. One major advantage is that they are wireless and don’t need to be plugged in for being operational. Rechargeable desiccant dehumidifiers are not suitable for use in large rooms or in extremely humid conditions. But they make a good option for small rooms with mild moisture levels.

3. Full-size consumer grade desiccant dehumidifiers:

Such dehumidifiers may be referred to as an alternative to the typical compressor based models. Available for a price in between $150 and $350, these desiccant dehumidifiers offer a decent rate of moisture removal. But still, they are small in size and possess limited moisture removal capabilities in comparison to the traditional dehumidifiers with compressors.

4. Commercial desiccant dehumidifiers:

Commercial desiccant dehumidification systems are usually used by different types of construction contractors. This is due to the fact that these dehumidifiers are extremely effective in drying up air as well as construction materials even in extremely warm or cold weather conditions. Majority of the commercial construction establishments prefer commercial desiccant dehumidifiers over compressor based models.

Who are Desiccant Dehumidifiers For?

Who should use desiccant dehumidifiers? Well, they are the perfect fit for anyone who loves to be in an environment that is clean and free of extensive moisture.
Some of the potential users who may get benefitted by a desiccant dehumidifier are listed below:

People who need to dehumidify an area with very low temperature:

Desiccant dehumidifiers are genuinely efficient for operating at low temperatures. As a matter of fact, a majority of the desiccant dehumidifiers can operate at a temperature range of 33 degrees F to 125 degrees F. So, those who need to dehumidify an area with very low temperature can be truly benefitted by a desiccant dehumidifier.

People who love to have fresh air in silence:

Desiccant dehumidifiers work on the basis of the desiccant rotary drum along with a couple air blowers. Unlike the typical dehumidifiers, they don’t have any noise producing compressors. Therefore, they operate quietly at less than 40 dB. So, if you want a good breathing environment without any noise, then you should go for the best desiccant dehumidifiers out there.

People who want to sustain a balanced indoor moisture level:

Compressor-based models are capable of bringing the humidity levels down to about 35%. Desiccant dehumidifiers, on the other hand, are efficient enough to sustain the moisture levels at 30%. So, desiccant dehumidifiers are the perfect fit for those who want to maintain a consistent indoor moisture level.

People who want to sustain a balanced indoor moisture level:

Desiccant dehumidifiers are lighter and much easier to move around than other compressor-based dehumidifiers. They don’t contain any heavy internal parts like a compressor. So, these are the undoubtedly the most beneficial option for people who need to replace their dehumidifiers on a regular basis.

People who need to dehumidify their daily used valuables:

Some nonelectric desiccant dehumidifiers are designed to dehumidify smaller enclosed spaces. Those can be good options for those who want to keep their valuables (like- camera, jewelry box, sporting goods etc.) safe.

How Does a Desiccant Dehumidifier Work?

A desiccant dehumidifier works on the basis of the desiccant rotor. It may be referred to as a massive rotating drum and is located in the center of the device. It has two operational zones – the process zone takes up 75% of the rotor area while the recharge zone comprises of the remaining 25%. The process zone pulls in the humid air where a certain desiccant material absorbs it in. After the absorption, it is exhausted out of the device immediately.

As far as the rotor’s recharge zone is concerned, it is covered by a heater. It is responsible for warming up the circulated air pulled out of the desiccant drum. The air heated in the recharge zone frees the desiccant from any moisture. So the moisture transfers into the air after leaving the desiccant.

After the air has left the recharge zone, it gets into a condenser located at the front side of the device. The condenser condenses the warm humid air and brings it to the room temperature. Consequently, the moisture starts condensing into a collection bucket just like it does it case of a compressor based model.

How We Picked and Tested

Our process of selection included extensive practical testing carried out by several volunteers. We have been in the business of reviewing dehumidifiers for over 4 years. In this period, we have carefully analyzed more than 20 different desiccant dehumidifiers. Neither one of these dehumidifiers may be listed as the perfect choice but they are definitely among the best ones out there.

Detailed Review

best desiccant dehumidifiers: This has to be the best desiccant dehumidifier out there!

Low temperature operation

Unlike the traditional compressor-based models, this unit is capable of providing low temperature operations. We were surprised to find out that it was powerful enough to operate at a temperature as low as 34 degrees Fahrenheit. It is almost impossible for a compressor based model to operate at such a low temperature.

Auto shutoff and auto restart

Detailed Review

best desiccant dehumidifiers: This might be the ideal choice for you if an expensive price tag doesn't bother you

Electronic controller:

This is one of the best desiccant dehumidifiers that features an electronic controller which helps you operate the device conveniently. It has several controls to help you run the dehumidifier at the required settings. We operated the product at different settings and it worked as per our expectations.

It’s slightly more expensive than the DD122-Simple even though it offers the same functions. But if price isn’t a concern, this desiccant dehumidifier is a great investment.

You can also buy: EcoSeb DD322EA-SIMPLE Desiccant Dehumidifier, 21-Pint, White, 120V

Larger moisture removal capabilities

This product boasts of the ability to operate at even the lowest temperatures to restore the air to optimum moisture levels.

Drying laundry indoors:

The turbo setting offered by the product comes in useful especially when you are willing to dry up your laundry indoors. We specifically liked the fact that there were two laundry modes perfect for dying up the laundry. The normal laundry mode runs the dehumidifier continuously with low power consumption.

Drawbacks of Using a Desiccant Dehumidifier

Limited capacity

Commercial desiccant dehumidifiers usually have large capacities but when it comes to desiccant dehumidifiers for homes, they provide a limited capacity. Majority of the products reviewed in this guide are capable of removing only 20 moisture pints per 24 hours.


Desiccant dehumidifiers tend to release a certain kind of pungent smell after operating for some time. This is due to the fact that during operation, these products absorb different odors present in your environment. These odors may originate from new furniture, building materials, cosmetics, cigarettes, etc.


Unlike the traditional compressor-based models, desiccant dehumidifiers usually have a limited lifespan. They are more delicate and tend to get damaged easily.

Care and Maintenance

To get the most out of your desiccant dehumidifier, it is critically important to take the right precautionary measures while operating them. You also need to carry out the necessary maintenance regularly to make sure your dehumidifier delivers perfect functionality for a long time.

Read the user manual and follow manufacturers recommendations:

The first and foremost thing before using a desiccant dehumidifier is to go through its user manual properly. You need to make sure you are completely familiar with the entire operations of the product put forward by the manufacturers before you try running it.

Keep your dehumidifier away from flammable liquids or gas storages:

While setting up your dehumidifier, it is important to make sure that there aren’t any flammable liquids or gases near the product. Otherwise, you might fall victim to some sort of destructive domestic accident.

Keep the power cords in check:

Desiccant dehumidifiers usually take up a considerable amount of electricity. Therefore, the condition of power cords matters a lot. It is strongly recommended to keep inspecting them on a regular basis and get them replaced as per the requirements.

Wrapping it up:
