Frigidaire FAD504DWD vs Keystone KSTAD50B Dehumidifiers

Various archeological discoveries show widespread use of mold as medicine in ancient Egypt, China, and Serbia. Have we gone a long way since then? Nowadays, pharmaceutical drugs have rendered such medical methods obsolete. Mold is now much more a serious health hazard than the solution to longer life.

Well, someone got sick of it – pun intended – and invented dehumidifiers. These tireless mechanical buddies exterminate mold from our homes, keeping it where it belongs – in laboratories and nature.

A good dehumidifier is mold’s natural enemy. It cuts its development dead by sucking the dampness out of the air. So, if you live in a humid place, a dehumidifier for your home is the right choice.

Overview of the models

Keystone KSTAD50B
This dehumidifier is one of the quietest ones in the market. It is also not far off from being the most efficient. It has a relatively big tank which allows for 50 pints of moisture to be sucked out of the air each day. The designers have made sure that the machine automatically turns off when the tank is full. This prevents accidental floods in your home. It has two fan settings, ‘normal’ and ‘turbo’, and an extra ‘auto-defrost’ setting, which we will explain further down. The hydrometer measures the humidity in the air with a deviation of just 2-3% from the real value.

Frigidaire FAD504DWD
You can set the humidity level you want in a room via the electronic controls. And although the dehumidifier will get you there, it must be noted that its hygrometer is not the most accurate – around 5% deviation from the actual value. It sucks moisture equivalent to 50 pints a day and can run continuously upon purchase of an appropriate drainage hose. The automatic shut-off option is also available. It has to be noted that this model is powerful – around 745 Watts at full capacity – making it louder than usual.

Controls

Keystone KSTAD50B
You can set the fan to ‘normal’ and ‘turbo’, according to the environment of the room which you want to dehumidify. There is also an extra ‘auto-defrost’ option which allows for the removal of frost from the evaporator coils as this could damage the machine. This is done via a sensor which temporarily turns off the compressor if it senses frost, which leaves room temperature air blowing at the affected spot. The sensor then turns the compressor back on when the frost is gone. You also have a timer set-up buttons and an LED display which shows the desired humidity.

Frigidaire FAD504DWD
You have ‘up’ and ‘down’ buttons to set up the desired humidity level anywhere in between the 35-85% range in 5% increments. You can also set the auto-shut-off timer up to 24 hours. The fan speed options are just two, high and low, depending on the room you want to dehumidify. You also have an LED display and lights to notify you when you need to change the filter and empty the tank.

Verdict: The glaring difference is that the Keystone possesses an auto-defrost option. Apart from that, both dehumidifiers have a low and high fan speed setting, a timer and an LED display that shows your desired humidity level.

Filtration and Water Level

Keystone KSTAD50B
A good dehumidifier wouldn’t be any good if it let the bacteria in the air survive the process. This is why the Keystone is equipped with a mesh filter behind the front grille that filtrates the air before it begins the dehumidifying process.

Checking the water level in the tank is a straightforward process. You have a slit through the cover where you can see the level of the water. To protect your home from unnecessary flooding, the Keystone is equipped with an auto-switch off function when the tank is full.

Frigidaire FAD504DWD
Bacteria, room odors, and airborne particles are barred from entering the dehumidifier by an easy-to-change mesh filter. This can be very useful if you are trying to protect valuable home property in very damp and dusty places like garages, basements, and rooms under construction.

The principle in evaluating the water level is the same. You have a slit in the cover through which you can see the progress. An LED light on the control panel lets you know when you need to change the water. There is no danger of flooding as this dehumidifier turns off automatically when there’s no more space in the tank.

Verdict: You won’t find any differences here. Both dehumidifiers protect you from harmful bacteria and airborne particles by using a mesh filter. Observing the level of the water is very easy and straightforward. Both possess the auto-switch-off option.

The punching power and noise pollution

Keystone KSTAD50B
This is all about the numbers. The KSTAD50B is rated at 590 Watts at its highest fan speed. Compared to other dehumidifiers at an average of 600 Watts, the Keystone is the most efficient option in the market, especially at its lowest settings. Not only that, but according to other reviewers, this dehumidifier is one of the quickest to do the job too. So, if efficiency is what you are looking for, this is it.

Although, not the best at containing sound pollution, the Keystone has been proven to emit around 50 dB sound at its highest setting. This is just a whisper above birds chirping. At its lowest setting, the dehumidifier is satisfyingly quiet.

Frigidaire FAD504DWD
The story is very similar here. The Frigidaire is rated at 530 Watts, but, in truth, it places close to the mid-600 range, according to multiple sources. Although not as environmentally conscious as other dehumidifiers, it is powerful. It takes just 12 minutes to reduce the humidity of a 50 square feet room to 40% from 90%.

It is slightly noisier too, but by a tiny stretch – just 67 dB at high fan speed and 62 dB at lowest.

Verdict: The Keystone takes this one. It is more energy efficient, more powerful and quieter than the Frigidaire. This, however, is compensated by a 6 ft power cord which eliminates the need for an extension cord.
