Best 70 Pint Dehumidifiers of 2022

Go big or go home.

Living in a humid area can affect your indoor air quality. As humidity levels rise indoors, health hazards such as mold and mildew will soon make an appearance. A study showed that relative indoor humidity could even affect the occurrence of respiratory infections as well as allergies (1).

It’s essential to keep the indoor humidity to a minimum level to avoid health issues and mold. One of the most effective ways to do so is by utilizing a dehumidifier. These devices will remove excess moisture from the air, leaving you with a comfortable home environment where mold and mites can’t live.

70-Pint vs. 50-Pint Dehumidifiers

If you’re familiar with dehumidifiers, you’ll know that there are different sizes, categorized by pints. You can find 30, 50 and 70 pints — but what are the differences? Most often, consumers compare 50 and 70 pints, so we’ll focus on these since they’re similar.


A 70-pint dehumidifier is designed to remove 70 pints of moisture in an area during one cycle. Now, because 70-pint units are designed to draw more moisture out of the air, they tend to work faster than a 50-pint.

Because of this, depending on the condition of your room, a 70-pint unit might not need to run for long. In comparison, a 50-pint removes 20 pints less than the 70-pint. As such it will need more time when placed in a very humid area.

Energy Consumption

This one is a bit more complicated to compare since it also comes down to how the specific unit was designed. Larger dehumidifiers will use more energy due to the size.

However, they’re generally fitted with various features designed to save energy. This includes an auto-shutoff mode and even low settings where the unit works at a minimum.

Now, if you were to place a 50-pint unit and a 70-pint in a large room, the 70-pint would finish quicker. This is, again, because it was designed to suit larger rooms.

However, if you were to place a 70-pint unit in a small room, it could be wasting energy since it draws so much when it’s not really needed.

70-pint units are generally more expensive than 50-pint dehumidifiers. They’re larger and often come with different modes and settings. However, the price will greatly depend on the brand and its specific use.

Built-In Pump vs. Condensate Pump

While searching for a new 70-pint dehumidifier, you’re sure to come across units with built-in pumps. These are designed to move the water vapor from the room constantly.

Dehumidifiers with built-in pumps will need to be located near a drain or vent, so the vapor can escape. If the outlet is facing the room, the moisture will be pumped right back into your living space.

Dehumidifiers without built-in pumps will have a collecting bucket for all the vapor. These come in different capacities and will need to be emptied every so often to avoid overflow.

Now, some consumers see this as a bit of an inconvenience since you can’t run the unit without having to empty the bucket. Many choose to get a separate condensate pump and hose.

However, not every unit will need a pump in the first place. Some dehumidifiers use gravitational force to remove the water when the bucket isn’t in use. Most of these units will be marked as having an optional continuous drain.

If your unit doesn’t have this force, a condensate pump and hose will be necessary to remove water vapor.

Isn’t It Easier With a Built-In Pump?

Yes and no; having a unit with a built-in pump will prevent you from having to do any manual work. However, these units tend to be more expensive and not as efficient as a non-pump unit.

More components could break or malfunction due to the added mechanics. Therefore, they’re not as reliable as non-pump dehumidifiers.

Finding the Best 70-Pint Dehumidifier for You

Hunting for the best 70-pint dehumidifier can be overwhelming. So if you’re unsure where to start, you’re not out of place. Fortunately, we’ve put together the ultimate guide to help you find the best unit for your needs.


Finding the right size of dehumidifier for you and your home is crucial. We already know that we need a 70-pint, but there are still different sizes to choose between.

70-pint dehumidifiers tend to be quite cumbersome, but it’s possible to find smaller, more compact designs. It’s vital to consider where the dehumidifier will be located. If you need it in your living room, for instance, a more compact design would be desirable since it will be more subtle.

On the other hand, if you need a dehumidifier in your basement, you could go for a larger model.


Due to the often grand size of 70-pint dehumidifiers, they can be tricky to move around. You can’t simply pick it up, so it’s important to look for a few features.

Wheels are super handy as they enable you to move the unit around effortlessly. Some dehumidifiers will also have handles to make it even easier.


Newer dehumidifiers will come with a range of features designed for safety and convenience. Here are some of the common features you’ll find:

  • Humidistat or hydrostat: This is an instrument fitted inside the dehumidifier that measures the relative humidity in the area. It passes the information back to the unit, which then adjusts to suit the conditions (2). Humidistats are handy since they allow you to set the device to maintain your desired humidity level.
  • Auto-restart: It can be frustrating to lose your settings due to a power outage or failure. Luckily, when your unit has an auto-restart, it will automatically save your settings and restore them when the unit is back on.
  • Auto-shutoff: When the reservoir begins to fill up, it runs the risk of over flooding if you don’t empty it in time. However, with an auto-shutoff, the unit will automatically turn off when the reservoir becomes full.
  • Full tank alert: It can be tricky to know exactly when the reservoir needs to be emptied. But many units are equipped with a full tank alert that notifies you when it’s time to empty the reservoir.
  • Clean filter alert: Because dehumidifiers draw air in, they’re equipped with filters to collect dust and debris. However, the filter will need to be cleaned from time to time to ensure the unit is working optimally. Some units are fitted with a clean-filter alert, which notifies you when it’s time for a clean.
  • Defrost: If the coils inside the dehumidifier freeze up, it can ruin the unit. A defrost function will quickly defrost the coils and keep the dehumidifier running smoothly. This feature is less common, but it’s necessary in cold areas.

Ease of Use

No one likes a complicated device where you need to press five buttons to turn it on. We prefer units with a simple LED display and a few marked buttons, so you know exactly what to press.

Another trouble-point for many homeowners is the reservoir or bucket that holds all of the water vapor. This component can be quite tricky to remove and replace in some units. With some units, it’s easy to take the reservoir out but challenging to put it back.

Make sure the unit you’re considering has an ergonomic design that makes it easier to use. We also recommend that you find a unit with a clear water level indicator, so you can easily see how full it is.

If your unit is equipped with a filter, how it’s removed should be considered as well. Having to take the unit apart to remove a filter is highly inconvenient. However, filters are usually easy to locate and remove.

Reservoir Capacity

The reservoir is where the water vapor will be collected, which means the capacity is crucial. Having a small reservoir means you’ll have to empty it more often. On the other hand, units with larger tanks tend to be larger in design.

A common size is around 1.5 gallons, but it can be anywhere up to and above 2.5 gallons. Consider your needs before settling on a unit.

The Best 70-Pint Dehumidifiers of 2022

Finding the best 70-pint dehumidifier for you requires more thought than simply choosing the highest rated. Our expert team combed through the most popular dehumidifiers on the market. Each unit was judged on how well it performed as well as how easy it was to use. These are our top picks.

1. Keystone High-Efficiency 70-Pint Dehumidifier

Best Features

The Keystone 70-pint dehumidifier is a favorite of many homeowners. First, it can cover large areas at a time.

It also has a substantial water reservoir, so you can go longer without emptying it. You get multiple handy features such as auto-restart, full bucket alert and water level indicator.

It’s easy to move around thanks to the four caster wheels and suits any type of room. The dust filter is easily removed and cleaned. The unit is also affordable in the long run since you won’t have to buy expensive replacements.

The Pros

Excellent for Large Areas

This dehumidifier can handle vast areas of up to 4,500 square feet. It effectively removes excess moisture of up to 70 pints a day. Set the unit to one of three settings, including normal, turbo and auto-defrost.

Smart Features

We love all of the features you get with this unit; they help to increase efficiency while making it easier to operate. Among the features, you get a 24-hour timer, water level indicator, full bucket alert with auto-shutoff and LED display. The auto-restart makes sure your settings are saved after a power outage.

Cleanable Filter

As the dehumidifier removes moisture from the air, dust is inevitably going to get caught in the filter. However, instead of having to remove and replace the filter, Keystone enables you to clean it. Quickly remove the dust filter when the alert notifies you.

Continuous Draining Option

With this unit, you get a 1.6-gallon reservoir, but you also get the option of connecting a garden hose for continuous draining. This enables you to run the unit without having to worry about a full reservoir. We think this is excellent for a humid basement where you might want to run it 24 hours or more.

The Cons

Bucket Tricky to Remove and Reinsert

To attach a hose and use continuous draining, you must first remove the bucket. However, this is easier said than done. Many customers found it tricky to remove the bucket and reinsert it.

For a compact and portable dehumidifier, we highly recommend this one from Colzer.

It has a very attractive design that doesn’t look as out of place as other units.

Additionally, it comes with multiple settings and options to help increase efficiency and make it easier to operate. When needed, you can use the included hose for continuous draining.

The Pros

Two Optional Modes

The two optional modes make this unit much more versatile. One is a regular dehumidifying mode, whereas the other is a “dry-clothes mode.” When in this mode, you can effectively dry your clothes even in highly humid weather

Intelligent Control Panel

We love how easy this unit is to operate, thanks to the LED display. You can control humidity via the setting button, check the humidistat and see humidity levels. When needed, you can set your ideal levels and adjust the fan speed to the desired level, or set the 24-hour timer.

Washable Filter

Sooner or later, the filter will need to be cleaned as dust and dirt build-up. You can quickly get this done by removing the filter and washing it with warm water. If it’s only slightly dirty, simply use the vacuum to remove loose dust and debris from the surface of the filter.

Automatic Drainage

When the tank becomes full, the full tank alert will notify you, so you don’t have to open it to check. You can also place the unit near a drain and use the included 6.6-foot hose to drain continuously.

Portable and Compact

This dehumidifier is slimmer and easier to move around compared to other units. It has a tall design that easily suits any room. You can quickly move the unit between rooms, thanks to the four universal wheels.

The Pros

Large Water Reservoir

If you live in an area with high humidity levels throughout most of the year, this is for you. This dehumidifier has an extra-large reservoir that can hold up to 2.25 gallons. It’s able to work for longer — compared to other units — without your having to empty the tank.

Maintaining a 70-Pint Dehumidifier

A dehumidifier can’t simply be activated and forgotten; you’ll need to care for it as recommended. Because these devices draw a significant amount of moisture from the air, growing mold and mildew within the unit isn’t unlikely.

Most dehumidifiers will have directions on maintenance and how often they need to be cleaned. Maintenance often includes removing the bucket to clean it. This can be done with regular dish soap.

The filter will also need to be cleaned, typically with a vacuum or it can be rinsed with water.

Keep In Mind

Always refer to the user manual to ensure you’re cleaning the filter correctly. Washing a non-washable filter will cause damage. The filter must be completely dry before placing it back into the dehumidifier.


Will a Dehumidifier Remove Mold?

No, a dehumidifier won’t kill or remove actively growing mold or mildew. It can, however, prevent future growth of mold and mildew by keeping moisture levels to a minimum.

The CDC recommends that you keep the humidity levels in your home no higher than 50 percent throughout the day (3). This will help to keep mold at bay. Most dehumidifiers can lower the humidity to levels between 40 and 30 percent.

Take Note

If you have actively growing mold in your home, you’ll need to have it professionally inspected and removed. Mold can cause various health issues, such as respiratory problems and allergies (4).

Where Should I Place My Dehumidifier?

A dehumidifier can be placed anywhere in your home where moisture is causing trouble. Some homeowners purchase a dehumidifier specifically to get rid of moisture in their basement. Others use it to improve the indoor environment in common living areas.

Creating a Comfortable Living

Having a dehumidifier can be essential if you’re living in humid areas.

High humidity indoors can be uncomfortable. But, more importantly, it can also lead to health problems such as respiratory issues. Mold and mildew are also more likely to grow in a humid environment due to the moisture.

Finding the best 70-pint dehumidifier for you can be challenging; there are many different models to consider. We highly recommend that you consider your needs and where the unit will be operated.
