Frigidaire FFAD7033R1 vs FAD704DWD

We will start by looking over the things the Frigidaire FFAD7033R1 vs FAD704DWD have in common.

While we are going to focus on the larger model (70pint capacity), you can also buy both in the 50 or 30 pints, depending on the size of the room or how severe the humidity is in your house.

The Frigidaire FFAD7033R1 and the Frigidaire FAD704DWD are white and come with four convenient wheels, a handle on the top of the machine and another handle on the side so moving the dehumidifiers from room to room is very simple.

We like the fact that both models have two ways of emptying the water. There is a tank at the bottom of the machine that you can pull out and empty or as long as you are close enough to a drain, you can use the hose to drain the collected water. Using a hose means you can use the dehumidifiers 24 hours a day.

Finally, the FFAD7033R1 and the FAD704DWD have electronic controls for easy use and a digital humidity readout so you are able to see what level you have the humidity set to.

The Frigidaire FAD704DWD


  • When running on the lower settings it is a really quiet machine
  • On a low setting, it can reduce the humidity by 1-2% a day
  • It works really well on old houses with high amounts of humidity.


  • It is not the most reliable dehumidifier

The Final Verdict
