Comparison Review: FAD504DUD and FAD704DUD

This brief & objective contrasting account will compare the Frigidaire FAD504DUD (50 pint) and FAD704DUD (70 pint) dehumidifier models, so you can clearly view the differences (as well as the similarities) between the two. Then from which you will then be able to easily assess which model is the most appropriate to your domestic setting and in turn which offers the best value for money.

How do they work?

The FAD504DUD & FAD704DUD are 50 pint (24 liters a day), 70 pint (33 liters a day) dehumidifiers, respectively that have the ability to continuously operate when in close proximity to a drain system. When they are turned on & are set to function (through the electronic panel) the fan inside the dehumidifiers draws in moisture from the air across the ‘dehumidifying coil’ & anti-bacterial filter -- which in turn condenses (and is collected in the bucket system, located at the front of the dehumidifier) and the air flow carries into the side louvers in your room as clean warm air.

This hence, prevents your home from growing mold etc. due to excessive moisture-laden air as well as to get rid of bacteria & odors, in turn leaving it instead smelling fresh and generally just being healthy & clean air supply.

Front Loading Bucket System & Auto Shut Off System

If you can’t connect it to a drain system you will have to empty the bucket -- it is placed at the front of the unit and comes with a splash guard & handle in order to minimize hassle and mess. Also, the unit will let you know when the tank is almost full and it is time to empty (with an Led indicator). On the display system it will read the humidity setting, so you will know the dehumidifier is actually working -- where you can also actually set the precise level of humidity between 35 and 85% (with the ready-select controls).

Portable & Compact

Both models are relatively compact & lightweight (see details below w. spacewise) and also offer a portable design given that they are set on caster wheels and feature handles to make it easy to manoeuvre around your home.

Further Information


They are backed for a full year on parts & labor costs and a 5 year limited warranty-sealed system.

Size (Dimensions) & Weight | Finish

FAD504DUD: 11.3 x 16.1 x 24.6 inches & approx 31 lbs | White finish.

FAD704DUD: 11.3 x 16.1 x 24.6 inches & approx 39 lbs | White finish.

Moreover, you will find that both models are also Energy Star Compliant, this is a certification to demonstrate that they require less energy than your standard domestic dehumidifer, in turn reducing your energy bills.

Conclusion -- How the FAD504DUD and FAD704DUD Compare & which to buy.

So basically get the model that suits the size of your house, if you have a large basement area that you want to stick the dehumidifer in get the larger FAD704DUD model -- if you only have a mid-sized to smaller basement then buy the FAD504DUD. The main difference which is of concern is just the amount of dehumidification (50 pints[1] compared with 70 pints[2]) the units can carry out in a day.
