  • 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.

What makes it special?

  • Built-in humidistat
  • Very quiet
  • Portable

What cons did we find?

Things to Consider

Before you dive into your next purchase of a 50 pint dehumidifier, it’s important to know as much as possible about these helpful devices. The following includes an overview of the features of a 50 pint dehumidifier as well as some answers to questions you’re probably wondering about. Together, the aim is to make this buying journey as easy as possible.

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.

Costway-Portable-50-Pint-Dehumidifier-Humidity-Control-Up-to-3000-Sq.Ft.-W--Fan-WheelsCoverage 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.


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

Ivation-70-Pint-Dehumidifier-removable-tank-e1542550363881After the moisture in the air has been circulated by a dehumidifier and turned into water, that water needs a place to be stored. Every dehumidifier will have a water tank, but some are larger than others. The products on our list range from a 0.8-gallon tank to a 2.0-gallon tank. The smaller the tank’s size, the more frequent you will need to empty it.

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.


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

frigidaire-50-pint-dehumidifier-handle50 pint dehumidifiers can’t be very compact due to the high dehumidification performance they feature. In fact, these devices are among the biggest on the market apart from the 70 pint dehumidifiers and those with even higher dehumidification rate. All of the 50 pint dehumidifiers on our list are roughly the same size. Their dimensions come in at around 12 x 15 x 24 inches. This means that they are too large for a shelf or table, and will need to be set on a floor.

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.


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.

Extra features

friedrich-d50bp-dehumidifier-lifestyleIf you purchase a standard dehumidifier, it won’t have many additional features, but it will probably be at an affordable price. More premium products will have extra features such as an LED or an LCD display. While manual settings are fine, digital controls are more precise and have more options. Other features, such as an auto shut-off control or defrost option allow you to worry less about your dehumidifier. You can plug it in, set it up, and not have to worry too much about maintenance.

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.


Dehumidifiers take moisture out of the air. That moisture is then transformed into water. A continuous drain option means that the water that accumulates in a dehumidifier can constantly be drained into your water system. The alternative would be models that have a water reservoir that needs to be emptied periodically. If you live in a very humid climate, then having a continuous drain option is exceptionally handy. By hooking up the water hose to your house’s drainage system, it eliminates the need to remember to empty the water reservoir. Plus, most models will automatically stop working if the water reservoir becomes full. A continuous drain option means that your dehumidifier can work around the clock without you having to worry about it.

All of the models on our list can be used in crawl spaces. 50 pint dehumidifiers are built to capture a lot of moisture from the air and store that water in their reservoir or be attached to a drain for continuous drainage. If you live in a larger house, be sure to purchase a 50 pint dehumidifier that has a larger coverage area that will work in a larger crawl space.

Thanks to advanced technology, 50 pint dehumidifiers are not noisy. Products will vary amongst each other as to the noise level, but for the most part, they have been designed to be as quiet as possible. However, the larger the machine, and the more intense the settings are, the more noise that may possibly be emitted. If you are very sensitive to white noise, then look to place your dehumidifier somewhere that is out of the way. All of the products listed are large enough to service considerable spaces, so they do not need to be placed right in the middle of a room. Find a corner to tuck your dehumidifier in, or better yet, place it in the basement. This way any noise that it does make will not interfere with your daily life.

Our Verdict

50 Pint dehumidifiers are large units that are built to service an open-concept room or even a whole house. All of the products on our list will work well, depending on your individual needs. For those wanting extreme coverage, the Tosot 50 Pint Dehumidifier can work with areas up to 3,000 square feet. It is powerful yet quiet and has great control options.

For those wanting a 50 pint dehumidifier that not only works well but also looks good, be sure to consider the hOmeLabs 50 Pint Dehumidifier. Its sleek, modern design means that it can sit comfortably in your living room and not be too inconspicuous.

Finally, for those who want a simple product that still works well, then the Keystone KSTAD50B is the way to go. It is also budget-friendly which makes it one of the best and most affordable 50 pint dehumidifiers.
