Your Guide to buying the best Dehumidifier


A dehumidifier is an essential home appliance for preventing mold, mildew, and moisture damage. The right dehumidifier for your home depends on your environment, space size, and humidity levels. This buying guide provides an overview of the different types of dehumidifiers available, along with information on how to choose the right model for your home. We’ll also cover the factors to consider when shopping for a dehumidifier, such as price, energy efficiency, and other features.

Key features

  1. Size - Consider the size of the dehumidifier to ensure it is suitable for the space you plan to use it in. Ensure it can fit in the space without overcrowding or taking up too much space.
  2. Capacity and Efficiency - Look at the capacity of dehumidifier, which is usually measured in liters per hour, and make sure it is suitable for the size of the space you plan to use it in. Also check the Energy Star rating of the model to ensure it is energy efficient.
  3. Moisture Removal Features - Look at the various moisture removal features such as auto shut off, adjustable humidity settings, timer, and air filter to ensure the dehumidifier can maintain a comfortable humidity level.
  4. Noise - Consider the noise level of the dehumidifier to ensure it meets your comfort level. Check the manufacturer's specifications for decibel levels.
  5. Maintenance - To ensure the dehumidifier runs optimally for a long time, consider the maintenance required such as emptying the water tank or changing the filter. Also check the warranty period.

Common questions

  1. What are the different types of dehumidifiers? The two main types of dehumidifiers are the compressor dehumidifier (also known as the refrigerant dehumidifier) and the desiccant dehumidifier. The compressor dehumidifier works by using a refrigerant to cool the air and condensate it, while the desiccant dehumidifier uses an absorbent material to absorb the moisture from the air.
  2. What size dehumidifier should I buy? The size of dehumidifier you should purchase depends on the size of the space you want to dehumidify. Generally, a larger dehumidifier will work better in larger spaces while a smaller dehumidifier will be better in smaller spaces.
  3. What are the features of a good dehumidifier? A good dehumidifier should have adjustable humidity settings, a timer, an energy-efficient compressor, a low noise level, and a filter to remove allergens and other particles from the air.
  4. What is the best location to place a dehumidifier? The best location to place a dehumidifier is in an area of your home that is close to a source of air, such as a window or door. This will help maximize the efficiency of the dehumidifier.
  5. How often should I empty the water tank of a dehumidifier? The water tank of a dehumidifier should be emptied when it is full, which can vary depending on the humidity levels of the space. It is recommended to check the tank at least once a day.
  6. What is the difference between a portable and a built-in dehumidifier? A portable dehumidifier can be moved from room to room and is usually smaller than a built-in dehumidifier. A built-in dehumidifier is stationary and designed to be installed in one location, usually in a basement or crawlspace.


In 2017, a woman in upstate New York purchased a dehumidifier from an online marketplace only to find out that it was actually a bomb! Fortunately, the bomb squad safely removed the device and no one was harmed. It is believed that a former military ordnance officer had mistakenly sent the device to the woman instead of the dehumidifier she had ordered. Source
