If you’re on a quest to find the ideal dehumidifier type for your home or office, you’re likely already familiar with the overwhelming amount of information available. But don’t worry, because you’re not alone!

In this guide I’m going to break down all the different types of dehumidifiers, each one designed to tackle specific humidity problems, and provide you with clear, straightforward advice to help you make the best choice.

So, let us dive into the world of dehumidifiers and unveil the key factors that set them apart.

Different Types Of Dehumidifiers

High humidity levels in your home are a complex issue influenced by a multitude of factors and circumstances. From varying climates to structural conditions, lifestyle choices, and even daily activities, there’s a diverse range of elements that can contribute to excessive moisture.

This complexity emphasizes the significance of choosing the right type of dehumidifier for your unique environment and specific needs.

A one-size-fits-all approach simply won’t suffice when tackling this multifaceted dehumidification problem. So let’s take a closer look at all the main types of dehumidifiers available:

Refrigerant Dehumidifiers

These are the most common kinds of dehumidifiers and work similarly to your refrigerator or air conditioning. They use a refrigeration process to condense moisture from the humid air into an evaporator coil, collecting the condensation in a removable tank or reservoir.

These dehumidifiers can be used for general humidity control and are suitable for moderate to high humidity levels. Refrigerant Dehumidifiers are perfect to control relative humidity in small spaces like bedrooms and living rooms.


  • Effective for general humidity control
  • Suitable for moderate to high humidity levels
  • Common and widely available
  • Collects moisture in a removable tank


  • Not as efficient in colder temperatures or very high temperatures
  • Not suitable for low-humidity environments
  • Higher energy consumption compared to other alternatives
  • Constantly produce condensate that needs to be drained or collected
Refrigerant Dehumidifier

Desiccant Dehumidifiers

Desiccant dehumidifiers work by using a moisture-absorbing material like silica gel to remove moisture from the air. They’re great for low-temperature environments and can operate at lower humidity levels than refrigerative dehumidifiers.

These units are quieter and more energy-efficient, making them ideal for laundry rooms, closets, and small spaces.


  • Work well in low-temperature environments
  • Operate effectively at lower humidity levels
  • Quieter and more energy-efficient
  • Are often smaller, lighter, and more portable than refrigerant dehumidifiers
  • Suitable for extremely low humidity levels


  • Lower moisture removal capacity compared to other types of dehumidifiers
  • Requires periodic replacement of desiccant material
  • Not as versatile, with a much limited operational temperature range

Whole-House Dehumidifiers

As the name suggests, these units are designed to dehumidify your entire home. Installed as part of your HVAC system, they’re perfect for maintaining a consistent humidity level throughout the house. They’re particularly useful in humid climates and large homes.

Whole-house dehumidifiers also require professional installation but offer optimal convenience.


  • Maintains consistent humidity levels throughout the entire house or office
  • Particularly useful for larger spaces or humid climates
  • Integration with HVAC system for convenience
  • Improved comfort for all occupants at once


  • Requires professional installation
  • Higher upfront cost compared to portable units
  • May involve more complex maintenance
Basement Type Dehumidifier

Basement Dehumidifiers

Basements often suffer from excessive humidity due to their location below ground level.

Basement dehumidifiers are specifically designed to handle these damp conditions. They have a higher capacity and operate in cooler environments, making them an excellent choice for cellars, crawl spaces, and basements.


  • Designed specifically for damp basement environments
  • High moisture removal capacity
  • Effective in cooler temperatures
  • Highly effective at preventing mildew, mold growth and musty odors


  • May be larger compared to other types of portable units
  • Professional installation might be required for certain models

Peltier (Thermo-Electric) Dehumidifiers

These compact dehumidifiers use a Peltier module to cool and condense water from the air. While they’re not as powerful as refrigerative dehumidifiers, they offer a great solution for an energy-efficient, quiet, and portable dehumidifier.

Peltier dehumidifiers are suitable for small spaces like bathrooms, closets, and RVs.


  • Energy-efficient operation
  • Quiet and compact design
  • Suitable for small spaces
  • High portability for easy relocation


  • Limited moisture removal capacity
  • Less effective in larger areas or high humidity levels
  • Slower performance compared to refrigerant dehumidifiers

Hybrid Dehumidifiers

Hybrid dehumidifiers combine the benefits of both refrigerative and desiccant technologies. They’re versatile and suitable for a wide range of environments and humidity levels. Hybrid units are often recommended for use in homes where the humidity level fluctuates frequently.


  • Combines advantages of refrigerative and desiccant technologies
  • Versatile performance for varying humidity levels
  • Effective for homes with fluctuating humidity conditions
  • Offers balanced amount of moisture removal


  • May be more expensive than single-technology units
  • Limited availability compared to other types
Commercial Dehumidifier

Commercial Dehumidifiers

Designed for commercial and industrial settings, these heavy-duty industrial dehumidifiers can handle large spaces and high humidity levels. They are used in warehouses, manufacturing facilities, and gyms to prevent mold growth and maintain comfortable conditions for workers and equipment.


  • Highest moisture removal capacity
  • Designed specifically for heavy-duty usage
  • Essential for industrial and commercial environments


  • Much larger and heavier units
  • Considerably higher energy consumption due to increased capacity
  • Professional installation and higher maintenance are required
  • Excessive for non-commercial scenarios

How To Choose the Right Dehumidifier

Selecting the best dehumidifier type for a given space requires a thoughtful evaluation of several crucial factors. As you embark on your journey to achieve optimal humidity levels, understanding the interplay of these various factors becomes paramount if you want your residential dehumidifier to not only solve your moisture-related challenges but seamlessly integrate with your lifestyle and environment.

  • Room Size: Consider the total area of the room you want to dehumidify. Larger spaces require higher-capacity units.
  • Humidity Level: Determine the current humidity level in your space. A hygrometer can help with this. Choose the best dehumidifier with the appropriate dehumidifying capacity for your desired humidity level.
  • Energy Efficiency: Look for the ENERGY  STAR label for more energy-efficient options, especially if the dehumidifier will be running continuously.
  • Noise Level: If you’re placing the dehumidifier in a bedroom or a quiet space, opt for models with lower noise levels.
  • Portability and Design: Consider whether you need a portable unit or one that blends well with your interior.
