Choosing The Right Dehumidifier

Water damage can be extremely costly and frustrating to deal with. If you’ve experienced it yourself, you’ll know precisely how extensive the damage can be. Fortunately, using a dehumidifier is an excellent solution to mitigate the damage and avoid future complications.

Types Of Dehumidifiers

There are essentially two types of dehumidifiers – desiccant and refrigerant. The desiccant works by absorbing moisture, while the refrigerant extracts moisture by passing air over a cold plate, condensing the moisture.

Factors To Consider When Choosing A Dehumidifier

To choose the right dehumidifier for your specific needs, take into account the following factors:

  • The size of the room- the larger the dehumidifier needed as determined by the cubic feet of your space, the more costly it will be.
  • The amount of moisture – determine if it’s a high or low humidity level. For instance, a unit that extracts 25 pints of moisture can handle up to 1,000 square feet with a 50% humidity level in 24 hours.
  • The temperature of the room – dehumidifiers operate best at an ambient temperature of 60-80 degrees fahrenheit.
  • The space required to dehumidify – choose the right type of dehumidifier for the job. For large open spaces, choose a refrigerant type, and for smaller spaces, choose a desiccant unit.

How To Calculate The Size Of The Dehumidifier You Need

To calculate the size of the dehumidifier required for your space, use the following formula:

  • Measure the size of the room in cubic feet by multiplying the width, length, and height of the space.
  • Determine the amount of moisture in the air by using a hygrometer or moisture meter.
  • Use a dehumidifier sizing chart to match the necessary capacity (pint rating) suitable for your space.

Choosing the right dehumidifier is crucial to successfully address water damage. Consider the factors mentioned above, and use the formula to calculate the size to ensure you get the appropriate unit for your needs.
