Frigidaire 50-Pint Dehumidifier
- Coverage area: up to 4,500 sq. ft.
- Pump: no
- Water tank capacity: 2 gal.
- Dimensions: 11.3 x 16.1 x 24.75 inches
- Warranty: 1-year limited; 4-year limited on the sealed system
More features: low-temperature operation; top handle, side handles, and caster wheels
The Frigidaire model is an all-around impressive 50 pint dehumidifier. Not only is it one of the best rated 50-pint dehumidifiers, as Amazon’s Choice, it is also affordable, coming in at just under $300.
One of the nicest factors of the Frigidaire dehumidifier is that it is very quiet. Numerous users have commented that once plugged in, they often forgot the dehumidifier was even on. The controls are also nice as the machine will measure the humidity in the air so that you know what to expect. Users also reported that the Frigidaire 50-Pint Dehumidifier worked well both to keep humidity at bay, and to help clean up after a flood. It’s a very versatile model.
The biggest drawback with the Frigidaire 50-Pint Dehumidifier is that there are a few conditions with where you place the device. For starters, it cannot be used with an extension cord. This can significantly limit its placement and is definitely not suitable for enclosed spaces like a crawlspace. However, as its room coverage is at 4,500 square feet, it is better suited for a living room or bedroom. One other placement constriction is that while it can be used to continuous drainage, it needs to be near a suitable drain. There is no pump included, so the water can only be moved downward. Again, this may impact the placement as it is probably not best suited for a basement.
- Built-in humidistat
- Very quiet
- Portable
- Cannot be used with an extension cord

Features to consider while choosing a 50 pint dehumidifier
The features of a 50 pint dehumidifier vary and are what set each product apart from each other. Here are some important features to consider with your purchase and what they all mean.
Coverage area
The coverage area of a dehumidifier refers to the square footage in which the machine will work with. Usually, the size and mechanisms of the unit will determine just how much room a dehumidifier will be able to work with. The mightiest models are the Keystone KSTAD50B and the Tosot 50 Pint Dehumidifier, both of which have a coverage area of 3,000 square feet. They can both serve a house or a very large office setting. In case you don’t need to dehumidify the entire house or a large room, search for a compact small dehumidifier that can be stored on your bathroom’s shelf, for instance. Such devices usually cover around 250 square feet – enough for a small room.
Pump
Of all the 50 pint dehumidifiers on our list, only the Friedrich D50BPA comes with a pump. A pump is needed so that you can drain the water from your machine into your house’s drainage system. Buying a dehumidifier with pump means that instead of having to always position the connecting hose down to allow gravity to force the water out, you actually have a bit more flexibility in positioning. This is great if you have a dehumidifier in a basement but need to connect it to a pipe above the unit.
Water tank capacity

Once a water tank has reached its capacity, it will stop filtering air until the tank is emptied. To remind you of that, dehumidifiers usually have an auto shut-off and an LED indicator.
Settings/modes/speeds
The optimal humidity level in a house is between 30 and 50 percent. It’s nice if you have a dehumidifier model that allows you to program this setting so that you don’t have to worry about constantly adjusting anything. As well, sometimes humidity can increase over night, especially in more tropical areas. Having a fast speed option allows the dehumidifier to quickly cycle through the air to give you a more instant relief.
Continuous drain option
There are two main types of dehumidifiers. Stand-alone products have a built-in water reservoir that needs to be drained in order for it to continue to work. There are also dehumidifiers that have a continuous drain option. By hooking up a hose from the dehumidifier to your house’s drainage system, you can run the device around the clock. It’s also convenient to use such dehumidifiers for bathrooms since you can just direct the hose into a sink. You don’t need to worry about emptying the water tank, and your dehumidifier won’t shut down waiting for it to be emptied. This is perfect for very humid climates.
Dimensions and weight

Before you purchase anything, plan where you want to put your dehumidifier and be sure to measure it. It’s important to find a product that will fit your space so that you don’t have to return it.
Warranty
Warranties are extremely important, especially with mechanical devices. All of the 50-pint dehumidifiers that we have assembled have decent warranties that are in effect for at least one year. The manufacturer of the Keystone KSTAD50B offers the best warranty terms. It has a one-year warranty on parts and labor as well as a five-year warranty on the sealed system.

Tips on how to maintain a 50 pint dehumidifier
50 pint dehumidifiers deal with water which can, unfortunately, lead to mold and mildew issues.
It’s important to regularly clean your 50 pint dehumidifier so that germs and bacteria aren’t able to grow.
You should also do a regular check up to make sure everything is in working order. Sometimes dehumidifiers are placed out of the way which makes us forget they are even there. Plan to do a quick inspection, say the first of every month, to ensure that no water is leaking and there are no electrical issues. If you have a one-year warranty, be sure to check in advance of this deadline so that if there are issues, you will still be covered.
