Things to Consider

All homes have issues with excess moisture at some point. Hot, humid climates, flooding, or even normal day-to-day activities like showering or doing laundry can contribute to this.

Getting your hands on the best home 50-pint dehumidifier can help take care of this dampness in your home, keeping things dry and preventing mold and mildew at the same time.

Advantages of 50-pint models

There are a few advantages that a 50-pint dehumidifier has over smaller models that pull 30 pints or less out of the air. The first and most obvious one is that these models remove more moisture out of the air in the same amount of time.

They also have larger coverage areas, up to about 3,000 square feet, like offered by the Shinco 50 Pint Portable Dehumidifier or the 50-pint Perfect Air dehumidifier, making them a much better choice for mid-sized rooms.

They can be used in a wide variety of areas, including bedrooms, bathrooms, kitchens, basements, or in the case of the AlorAir Basement/Crawl Space Dehumidifier, crawl spaces.

Features to consider while choosing a 50-pint dehumidifier

If you’ve decided you need a 50-pint dehumidifier for your home or workspace, there are a few features you may want to consider checking out before you buy one. This will ensure you are getting everything you need in a dehumidifier.

Coverage area

The coverage area of a 50-pint dehumidifier tells you the maximum size the room you’re using it should be for it to perform properly. Most of the models we’ve reviewed have a coverage area of 3000 square feet, which is pretty large for a single room.

The AlorAir Basement/Crawl Space Dehumidifier has a coverage area of 1,300 square feet, which is still quite a large area for the dehumidifier to work in. As long as the space you put the unit in is this size or smaller, it will have no trouble pulling its specified 50 pints of water out of the air in a single day.

If you try to use it in a larger area, though, it may not work to its full potential as there is a lot more air to circulate through it.

Water tank capacity

The water tank capacity tells you just how much water the dehumidifier can hold as it removes the moisture from the air. This can vary, from just over a gallon to the huge two gallons offered by the TOSOT 50-Pint Dehumidifier.

The more the tank can hold, the less often you have to empty it throughout the day. This means you have to work less often, though the larger tanks will be a bit heavier when they are full of water and in need of emptying.

The smaller tanks are lighter when full, but require draining more often.

Continuous drain option

Every one of the models we’ve reviewed here offers the continuous drain option. This means that instead of using the tank to collect water, you can hook up a hose to the unit so it can automatically drain as it collects the water. This means you no longer have to worry about emptying the tank as long as you’ve set it up for this function.

Of course, to use the continuous drain function you do need to have an actual drain nearby. Most of these are gravity drains, too, so it needs to be on the same level or a bit lower than the dehumidifier for gravity to pull the water through the hose and into the drain.

Built-in pump

A dehumidifier with a built-in pump, like the Whynter 50 Pint Dehumidifier with Pump, can be handy to have. The gravity drain is great for continuous water removal, though you need a drain you can run the water to. The water tank collects the water but needs to be emptied daily, which can be a hassle.

The built-in pump pushes the water out of the connected hose, even if it’s draining into a sink that is above the unit itself. This way, you can drain the dehumidifier pretty much anywhere you like, which can be convenient if there is no floor drain nearby.

Noise level

The noise level of any appliance in your home is pretty important. You don’t want to buy one that drowns out your conversations or has you cranking up the volume of your television.

Thankfully, there are a wide variety of quiet 50-pint dehumidifiers on the market, like the TOSOT 50-Pint Dehumidifier, which only runs at 48 decibels.

These are great models for use in your bathroom, laundry room, kitchen, or even your bedroom if needed, all without disrupting your normal daily routine, even when you’re running them all day and night.

Dimensions and weight

If you’re putting your new 50-pint dehumidifier into a large, spacious basement, the dimensions may not matter. However, the smaller the space you have, or the more cluttered it is, the less room you have for a dehumidifier to fit in.

That’s why you should always check out the dimensions of the unit and compare them to the space you plan to use it in. If it fits well, and there is a wall outlet nearby for the cord to plug into, you likely have the right machine for your needs. If it doesn’t fit there, try a new spot or a smaller unit.

When it comes to weight, you want a unit that is easy to maneuver on your own. If you can’t carry it down the stairs to your basement or move it where you want it, it won’t be much use to you. A lightweight model is easier to move around where you need it, especially if your moisture issues vary from season to season.


We all hope that the products we buy will last for as long as we need them. Unfortunately, there are issues with internal parts, manufacturing errors, or even shipping damage that keeps some of the items we buy from working as they should and dehumidifiers are no exception.

That’s why you should always check out the warranty details of the 50-pint dehumidifiers you’re considering buying for your home. A one-year limited warranty for the entire unit is common, though some models add some extras as well.

For instance, the AlorAir Basement/Crawl Space Dehumidifier has a one-year limited, with a three-year warranty on the refrigeration circuit and a five-year limited warranty on the compressor. Be sure to check out all the warranty details, so you know exactly what you’re covered for.

Extra features

Extra features are always a nice addition to a 50-pint dehumidifier. One good one to look for is LED/LCD indicators, which usually let you know what settings you’re on, if the tank is full, or if the filter needs cleaning.

Multiple speeds allow you to clear out the moisture quickly or just maintain the level you’ve set. The controls should be clear and easy to use. An adjustable humidistat lets you choose the humidity level you want. An auto-shutoff turns off the unit once the tank is full rather than letting it overflow.

Another handy feature is the auto-restart for power outages, which saves your settings and, in some cases, restarts the unit when the power comes back on.

How to maintain a 50-pint dehumidifier

Maintaining your 50-pint dehumidifier can increase its lifespan, so try out the following tips to keep working properly:

  • Set the humidistat at about 45-50% humidity.
  • Clean or replace the filter regularly.
  • Wash the water tank regularly to reduce bacteria growth.
  • Clean the air intake and exhaust grilles to reduce airflow blockage.
  • Wait at least 10 minutes after turning it off to turn it back on to prevent compressor damage.
  • Check the condenser coils for the build-up of frost or ice.
  • Place the dehumidifier at least 6 inches away from walls or furniture to ensure proper airflow.


How often should the water reservoir be emptied?

This depends on the humidity levels in your home. Initially, when you first set up your dehumidifier, the humidity levels may be quite high, so the tank will fill up faster than normal for the first few days. This may require you to empty it two or three times each day.

Once the humidity is in a normal range, you may only need to empty the tank every few days. During rainy seasons or flooding, the levels may rise again, so you may have to empty it more frequently again.

Is it safe to use in homes with children and pets?

Dehumidifiers are quite safe for homes with children and pets. They are built well, with no harmful parts that could harm kids or pets. They also help clear out the excess moisture from the air, reducing mold or fungus growth.

This makes the air safer for the whole family to breathe. Most models also include some sort of filter which helps remove other unwanted particles and odor from the air for even cleaner air.

What is the continuous drainage option for?

All of the products we’ve reviewed have the continuous drainage option, which allows you to attach a hose to the dehumidifier. Instead of the water collecting in the internal water tank, it will automatically drain out through the hose and down a nearby drain.

This is more convenient since you never have to worry about the unit shutting down when the tank is full and you never have to empty it.

Our Verdict

The mid-sized areas of your home need a decent dehumidifier to get rid of the moist air that’s making you uncomfortable. The best 50-pint dehumidifier can get the job done in no time. If you’re in the market for one, here are our top choices.
