Dehumidifiers - Advantages & Costs

Dehumidifiers can help control moisture in your home, but what about the cost?

A dehumidifier can be a great addition to any home in climates that are particularly humid. Not only can it be quite uncomfortable to live in that kind of humidity, but the added moisture can be a major detriment for the health and cleanliness of your home.

However, if you are using a dehumidifier to help control excess moisture in your basement this summer, that may be why you are seeing a rise in your energy bill. The amount of electricity required to operate a portable dehumidifier varies and so does the time required for the appliance to do its job.

Here's an example: A 50-gallon Energy Star rated dehumidifier requires 530 watts to operate. If it operates for 12 hours each day to keep the space at a humidity level of 40 percent, your cost would be 75 cents per day.

Savings tips to increase the efficiency of your dehumidifier:

  • Make sure your dehumidifier is Energy Star rated. 
  • Close doors and windows when the unit is in use.
  • Place dehumidifier away from walls and furniture to allow air to circulate freely around the unit.

One of the most important things that you want to keep in mind with a dehumidifier is the energy consumption or kilowatt-hour (kWh) of the device that you go with. You’ll want to know just how efficiently the device that you choose uses that energy.

You should be able to find the energy consumption rate on the sticker or label on the dehumidifier itself. The energy efficiency, which may also be known as the energy factor, is based on the kWh, which tells you how much water will be removed from the air for every kWh.

While costs are certainly an important factor to keep an eye on, the whole point of the dehumidifier is to drain out the moisture that can make the air feel heavy. It is recommended that you run a dehumidifier for at least 12 hours each day. This can depend greatly on how damp the room you’re using it in is, the capacity of the unit, and any built-in features that the dehumidifier may have.

If you are trying to improve the condition of a room that is very damp, it may be a good idea to let the dehumidifier run for the whole day or perhaps a few days to get the air quality and moisture levels where you would prefer them to be.

The amount of power and the subsequent cost of running a dehumidifier all comes down to the size of the room. The bigger the room, the longer you will need to keep it on. And the longer you keep it on, the more money it will cost in the long run.

Also, consider the space that you plan to run the dehumidifier in. How big is the space? Just how humid is it in that space? What do you use the space for? Keep those things in mind before you purchase your dehumidifier.
