While the desiccant and compressor dehumidifiers both serve the similar purpose of removing moisture from your workspace, they each have specific limitations and efficiencies. Before deciding which one to choose, let us briefly explain both types, along with their working mechanisms, efficiencies, and limitations.
How Does A Desiccant Dehumidifier Work?
The desiccant dehumidifier uses a simple yet effective technique. It removes moisture from the air by absorbing it through a desiccant material, usually silica gel, as it is an effective absorber of moisture. The moisture absorbed by the gel is heated to evaporate it in the form of vapors.
What Is The Working Mechanism Of A Compressor Dehumidifier?
A compressor dehumidifier captures moisture in the air. The air is condensed into water, which is transported into the tank and ultimately disposed of. The dry air that is free from moisture is released back into the room.
Difference Between Desiccant And Compressor Dehumidifier
Desiccant Vs Compressor Dehumidifier Efficiency
The compressor dehumidifier wins the debate when compared in terms of efficiency and performance. They can remove moisture from large spaces more quickly than desiccant dehumidifiers. They are also the best option for dealing with high moisture levels in high-humidity areas.
Conversely, desiccant dehumidifiers work best at lower temperatures and humidity levels. They are also much slower at removing moisture.
Desiccant Vs Compressor Dehumidifier Running Costs
When comparing the two types of dehumidifiers concerning their prices, it costs you less to buy the compressor dehumidifier. In contrast, the desiccant dehumidifier is slightly more expensive than the compressor one. This feature may attract many buyers, but the running cost of both dramatically depends upon the temperature of the area where they are intended to be used.
The running costs of the two differ significantly. Desiccant dehumidifiers are slightly overpriced when bought, but if you reside in a low-temperature region, their running cost in freezing temperatures is less than that of the compressor dehumidifier. On the contrary, the compressor dehumidifier gives the best value for money in warm regions and industries, which are usually warmer due to the continuous operation of machinery.
Desiccant Vs Compressor Dehumidifier Noise Level
The compressor’s working is why the compressor dehumidifier is a little noisy compared to desiccant dehumidifier. The desiccant dehumidifier may make some noise due to the fan running, but it is lower than the compressor dehumidifier.
A desiccant dehumidifier noise level is as low as 35 dB (decibels). In contrast, the lowest noise level for a compressor dehumidifier is around 45 dB (decibels).
Desiccant Vs Compressor Dehumidifier Maintenance Requirements
Desiccant dehumidifiers aren’t based on a compressor, like a compressor dehumidifier, and thus are easier to maintain, as their working mechanism is pretty simple.
The compressor dehumidifier requires refrigerant gas to run and may need to be refilled periodically. The coils may also need to be checked for maintenance. Similarly, the desiccant material in the desiccant dehumidifier needs to be replaced after years.

Desiccant Dehumidifier Vs Compressor Pros And Cons
Pros Of Desiccant Dehumidifier
No Drainage Required
One significant advantage of a desiccant dehumidifier is that it doesn’t require any drainage setup. It removes moisture from the air using a gel or desiccant material. A heating element evaporates the collected moisture. This mechanism is handy at workplaces where a proper drainage setup cannot be implemented, or the temperature is below the freezing point.
Lightweight And Portable
Another perk of a desiccant dehumidifier is its easy movability and lightweight design. It can easily be moved from one room to another or even from one place to another, as no drainage setup is needed for its operation.
Low-Maintenance
Unlike compressor dehumidifiers, desiccant dehumidifiers don’t comprise any coils or technical mechanisms to handle faults or routine maintenance. They also free you from the regular emptying of the water tank. The only maintenance regime you need to follow is cleaning the filters every month; otherwise, it’s a hassle-free device for your workplace.
Cons Of Desiccant Dehumidifier
Limited Efficiency
One of the most notable drawbacks of desiccant dehumidifiers is their limited efficiency in removing moisture. They are less competent than refrigerant or compressor dehumidifiers. If intended for use in a vast workspace or high-humidity area, they may be a total waste of your hard-earned money.
Costs More In Warm Areas
If the temperature is high, they may use more power than compressor dehumidifiers, which ultimately leads to increased humidity at your workplace. In order to reach the desired humidity level, their power consumption is prolonged and it will cost you more than a refrigerant dehumidifier would have cost in the same scenario.
May Generate Some Heat
Due to its working mechanism for removing moisture, it may generate some heat, elevating the overall temperature of the place. This may cause an increased need for air conditioners, mainly if your workplace is already warmer.
Pros Of Compressor Dehumidifier
High Efficiency
Compressor dehumidifiers are a highly efficient option for any industrial setup. They are a quick and reliable way to control a place’s humidity. Due to their efficiency, they are highly recommended for industrial setups and basements, as they prove to be cost-effective and efficient at the same time.
Suitable For Large Spaces And Industries
The compressor dehumidifier can accommodate large workspaces and enclosures, regardless of the nature of industrial activity. It’s effective in balancing the humidity level in your factory premises, warehouses, and even the basement, which are comparatively higher in humidity than the rest of your workplace.
Suitable For Warm And Humid Areas
The compressor dehumidifier is the most suitable option for an area with high humidity and temperature. It is also the best option for an industrial setup, as industrial places have high humidity due to the ongoing work of machines.
Cons Of Compressor Dehumidifier
Heavyweight And Less-Portable
The compressor dehumidifier is a heavyweight device that makes it challenging to move around freely. Due to its weight, it is a less portable option and is preferred for use in one place. Also, the drainage setup, which is usually connected through a hose to any nearest sink or sewerage, makes it challenging to move around.
The good news is that many manufacturers have overcome this drawback and made advancements in their design by adding wheels to the dehumidifier to make it portable despite its heavy weight.
Need Periodic Maintenance
A compressor dehumidifier needs to be maintained periodically. It should be appropriately cleaned and checked at least once a month. The filters and coils need to be cleaned. The water tank must be emptied and thoroughly cleaned to prevent mold growth. You also need to check the drainage system for any age or faulty parts every now and then.
Need Proper Drainage Setup
The compressor dehumidifier needs a proper drainage setup. Either you need to check and empty the water ranks regularly, or if it is connected to a hose to any sewerage line, you must check for blockages or leaks in the hose periodically.
Desiccant Vs Compressor Dehumidifier Which Is Better?
So, which type of dehumidifier should be bought?
The selection of the most suitable type of humidifier for your workplace depends upon its intended application. You must have a clear mindset about the scenarios and environmental conditions. If the climatic condition of your area is such that the temperature falls below the freezing point, the desiccant dehumidifier is the most appropriate one. On the contrary, an area with high temperature and high humidity will not be an ideal scenario for a desiccant dehumidifier. It will cost you more and bear no satisfactory results. You will need a refrigerant dehumidifier instead.
In the same manner, a compressor dehumidifier must be your top pick if you are looking for a dehumidifier for your basements, warehouses, or vast workplaces.
In A Nutshell
After weighing the pros and cons of both, it wouldn’t be wrong to say that if you are looking for a dehumidifier for your vast workplace, choose a compressor dehumidifier. Choose only the desiccant dehumidifier if the temperature is at freezing level. While choosing any of the types, don’t forget to check the environmental conditions and your intended use.
