Normal portable dehumidifier verse Aprilaire dehumidifiers

Question submitted from the consumer blog:
We have a small Whirlpool dehumidifier that is run by compressor generally it’s designed for one room or a certain amount of square feet. Are we using more electricity by using this in the summer…as it blows out hot air..basically it’s in my opinion a small window air conditioner reversed as a heat pump would be, question is can’t tell much difference with it on or off except in the room it is in..but since there is a 10 volt compressor at work and our forced air system is running a huge 240 volt compressor does this make this little unit effcent enough to use it, since we are re cooling the hot air it blows out, it is Green star energy rated..and in a day will remove about 3 gallons of water……could this make our electric bill way higher than usual, and should we think of a whole house instead of buying other dehumidifies for the rest of the house. Any info would be of great help.

Aprilaires’ response:

Thank you for contacting us with regards to your dehumidifier. Certainly, you are using energy to condition the space it’s in. Generally, the way a dehumidifier saves you energy is by making the home more comfortable so that you can raise the temperature on your thermostat by a few degrees. By running your A/C less, your energy bill goes down. Whole-home dehumidifiers can remove 8 to 17 gallons of water per day, depending on unit size and capacity. Compared to portables, they will use 1/2 to 1/3 of the energy to do the same work. You can find our product brochure at
