What Does a Dehumidifier Do

When you spot condensation your windows or see some mold or mildew in different parts of your house, then you may have a moisture problem. As the weather gets hotter and more humid, window air conditioners and other air conditioning models may not be enough to stop the excess moisture from entering your home.

In this situation, you need a machine that is dedicated to removing that moisture and keeping your home nice and dry. That is what a dehumidifier does. It removes that excess moisture and brings your interior humidity levels down to where they are comfortable.

As your new dehumidifier works, it either sends that excess moisture to a built-in and removable water tank. Once that tank gets full, the dehumidifier will turn off and wait till you empty the water tank. Then the unit will fire up again.

Or it uses the continuous water drain feature you set up. This feature spares you the trouble of constantly emptying the water tank.

Where do You Locate a Dehumidifier?

You can place these appliances in just about any room you want. The trick is, of course, not to put them in a room they are not rated to work in. If you put a small dehumidifier in a large room, then you will not remove any excess moisture from that room.

You need the right sized and rated dehumidifier for the room it has to work in. Here are some of the prime locations to place your new dehumidifier:

The key to getting the best results is to make sure the dehumidifier is not near a wall or other obstacles. These items block the air flow and make your dehumidifier work harder.

How Does a Dehumidifier Work

Unlike an air conditioner, a dehumidifier doesn’t cool the air in the room. It simply removes the excess moisture and lowers the humidity levels inside your home. The dehumidifier does this n several ways. The most common way is for the unit to use a compressor and fans to bring the moist air over refrigerated coils.

This draws the moisture out of the air and sends it to your water tank or continuous drain feature. Another method is the desiccant dehumidifier which has materials inside to soak up that moisture and send it to the water tank.

How to Choose the Best Dehumidifier

There are several criteria you need to use to determine which dehumidifier you buy.

  • The square footage of the room – if you have a 1000 square foot room that needs help, then you need a dehumidifier rated for 1,000 square feet or higher. See the sizing guide here.
  • How many pints per day will it take out of the air – dehumidifiers come in a variety of sizes from 30 on up to 70 pints. That number tells you how many pints per day the dehumidifier will clear out of a room. The heavier the humidity in your area means you want a larger capacity dehumidifier
  • Energy efficiency – you want one that does not use a lot of power while it does its job.
