What's the Difference?

A dehumidifier can be an essential piece of equipment in your home. If you live in a particularly humid area, have basement level rooms, or even a bathroom with poor ventilation, a dehumidifier might be a life saver.

By sucking extra moisture out of the air, a good dehumidifier can decrease the chance of mold or fungus growing in your home. But more importantly, a dehumidifier will also decrease the chance of health problems that come from either mould or living in a damp environment, such as breathing problems, allergies or asthma. So getting the best device is essential, you want a dehumidifier that's really going to get the job done.

Here we're comparing two great models that may appear similar but are actually rather different -- the FAD704DWD Vs FAD704DUD. Want to make sure that you're making the right purchase? Then read on to find out more...  

Frigidaire Dehumidifiers...

Both of the devices we're looking at today come from Frigidaire, one of the top names in home electronics and dehumidifiers. Choosing Frigidaire means that you already know that you're getting good quality, so you have nothing to worry about on that score. But both the FAD704DWD and the FAD704DUD are seventy pint capacity dehumidifiers that even look almost the same. So, you might be wondering what the difference is between these two models.

The Essentials...

These two devices do have a lot of similarities, and when it comes to the essentials they are pretty much the same. They have the same seventy pint (thirty three litre) capacity, automatic shut off, clean filter and full tank alert systems. They also both importantly have a continuous drain option, meaning that as long as you locate your dehumidifier next to an appropriate drain outlet you can leave the device running and the water will drain automatically, preventing the tank from overfilling. They're front loading devices, which is convenient since it means that you don't need to move the appliance in order to physically drain water from it, and they're also both extremely portable and space efficient, and weigh only forty six pounds. Essentially, these are the same machine, but there are a few very important differences...

How They're Different...

There are four big differences between these two dehumidifiers.

The first lies in price, since the DWD is the more expensive of the two, this is due to the fact that the DWD has three additional features that the DUD does not have.

Moreover, the DUD also has electronic controls that feature a digital read out of the amount of humidity in the air, making it slightly easier and more convenient to use. And finally, the DUD also has low temperature operation -- this means that the device is specified for use at temperatures below around 45 F, whereas many other devices may have problems functioning at these temperatures (such as the DWD at 65 F).

Ordinary dehumidifiers may get frost forming on the internal condensing coils once temperatures fall, which prevents the coils from performing properly and means that the compressor in the device continuously switches off and on, wasting electricity and meaning that moisture isn't removed from the air. This low temperature operation is a real boon if the space that you're dehumidifying regularly gets cold, and it will help prevent you getting large electricity bills.

Which is Better?

Obviously, the FAD704DUD is the better device, which is why it's more expensive (generally speaking, although prices will obviously differ from retailer to retailer). The addition of low temperature operation and two fan speeds will help you cut energy costs, meaning that even though the DWD is more expensive you'll end up saving money in the long run. That being said, should you live in a warm climate, or be continually dehumidifying an indoor space that's heated then the low temperature operation function will probably not be necessary for you, and therefore won't be worth paying extra for.

In all, both the FAD704DWD and the FAD704DUD are great dehumidifiers, and which you choose probably has more to do with the temperature of the planned location of the device than anything else.
