What Size of Dehumidifier do I Need?

Everyone needs a dehumidifier in their space. Whether you are a business or a homeowner, a dehumidifier can significantly improve the air quality in your environment. What size of dehumidifier do I need? Now, this is a question many consumers ask before making a purchase.

Humidity can cause several problems, from mold in your cupboards and computers, allergies and damaged furniture to rusting of short circuits

If you buy the wrong size of a dehumidifier, you may get stuck with an energy-draining device that will cost you more to keep. A small dehumidifier, on the other hand, may not adequately dehumidifier your space.

In this post, we will share some pointers to help you determine the size of the dehumidifier you need. Firstly, here’s how a dehumidifier works.

How a Dehumidifier Works

A dehumidifier removes excess moisture from the air, improving your space’s overall air quality and comfort.

A dehumidifier functions just like a vacuum cleaner. It sucks the moisture out of your space and blows it back into the room again. Typically, a dehumidifier comes with a collection that needs to be emptied when it gets full. During the process of moisture removal, the dehumidifier works just like the air conditioning unit.

  • The moist air is drawn through a duct
  • The removed air goes through a rotating wheel which removes the moisture.
  • A man operated by an electric motor draws the air.
  • Dry air is released back into the room.
  • The rotating wheels responsible for moisture absorption dry the air out.
  • The hot wet air is released through an exhaust duct.
  • A dehumidifier is designed with a humidity sensor that makes the room as hot or dry as you wish.

Why You Need a Dehumidifier

Although some areas have it worse than others, you must have surely experienced that muggy, heavy filling that fills the air when it’s raining or hot outside. Depending on the temperature, the air can hold water.

When the humidity seeps into your home, it can create discomfort and even a musty smell in your environment. Too much moisture can do damage to your structural integrity, attract pests and cause respiratory illnesses.

The temperature in the average room is about 68 degrees Fahrenheit. However, the relative humidity should be between 30-50%. If you are struggling to reach this range, a dehumidifier can come in handy.
