How do dehumidifiers work?

Most dehumidifiers work in the same basic way. The dehumidifier uses a fan to suck in air. As this air moves through the dehumidifier, it passes through cooling coils, which remove moisture from the air. This air is then reheated and redistributed back into the room.

The moisture is collected in a tank or reservoir that you can empty. Most dehumidifiers will shut off when the water tank is full to prevent overflow.

How do I know if I need a dehumidifier?

If your home has any of the following warning signs, you should consider getting a dehumidifier:

  • Water damage or stains on walls or ceilings
  • A musty or mildew smell
  • Mold or small black spots growing in high-humidity rooms
  • Rotting wood
  • Rooms with high humidity and little or no ventilation
  • Regular condensation on windows and doors

How to compare when choosing a dehumidifier

A dehumidifier typically costs between $140 and $1,000. Choose a dehumidifier based on the size of your room or home, and the humidity and temperature of your environment.

When comparing dehumidifiers, look for the following additional features:

  • Humidistat. A humidistat allows you to choose your desired humidity in a room. The dehumidifier then works to meet this target and shuts off before overdrying your room.
  • Drain. If you’ll always be using your dehumidifier in the same room, you can get a model with a tank that drains down a hose and directly into a drain so that you don’t have to empty the tank manually. You should still clean the tank regularly.
  • Wheels and handles. Large dehumidifiers can weigh 65 lbs or more when empty — and significantly more when full of water. Wheels and handles will make your life easier every time you have to move your dehumidifier or empty the tank.
  • Dust and UV filter. Many dehumidifiers come with dust filters, and some include UV light filters that help kill bacteria.

Bottom line

If your home has too much moisture, your health, home and belongings could be affected. Buying a dehumidifier is a cost-effective method of reducing mold and dust and saving money on costly home repairs.
