Best 70 Pint Dehumidifier in 2021

Let’s find the best 70-pint dehumidifier for your home!

When the air in your home gets too humid, it can trigger allergies, cause mold and bacteria to grow, and make your living areas stuffy and uncomfortable. A dehumidifier can solve all these problems by removing moisture from the air, and a 70-pint dehumidifier is enough to work effectively in even the largest and most humid homes!

To learn about what to look for when buying a 70-pint dehumidifier, read on or use this convenient table of contents to skip to my dehumidifier reviews 70-pint. 

I’ve got over a decade of experience working as a licensed Heating, Ventilation, and Air Conditioning (HVAC) engineer. I’ve used that knowledge and experience to help you find the best 70-pint dehumidifier that can solve your high humidity issues. 

There are so many to choose from in a saturated market, but not every 70-pint dehumidifier will offer the features that you and your home need the most

So I’ve compiled this buying guide, as well as a best 70-pint dehumidifier review, to help you make the right choice for yourself and your home!

70 Pint Dehumidifier Buying Guide

The following are the most important things to think about and look for when you’re shopping for the best 70-pint dehumidifier for your home.

Dehumidifier Pumps

One of the first decisions you’ll need to make when choosing your 70-pint dehumidifier is whether or not you need or want a system that has a built-in pump

A unit without pump drainage will need to either be manually and periodically emptied or will rely on gravity drainage. In this case, it will need to be mounted in an elevated position that ensures water flows from the unit, down the drain hose, and into a drain. 

Both options are somewhat inconvenient since you’ll need to consistently monitor the water levels of your unit or place it in a position dictated by gravity drainage. 

A built-in pump gives you the flexibility to place your 70-pint dehumidifier in a place that suits you best. This could be somewhere out of sight or in another convenient location. Without having to keep checking back on water levels and manually drain the tank, you’ll save a lot of time and effort. 

70-pint dehumidifiers with a built-in pump are generally more expensive, but it’s a convenient feature that can bring extra comfort with your purchase. 

Design And Ease Of Use

Many 70-pint dehumidifiers, even those from different brands, will quite often look very similar and, in some cases, almost identical. You’ll find that most units are between 15” and 30” tall, with a water bucket and a humidity control panel. 

These external similarities don’t mean that all the parts inside one unit work as well or in the same way as those in another unit. 

Regardless of the 70-pint dehumidifier you eventually choose, you should look for a unit with an easy-to-empty or even spill-proof water bucket, so water drainage is simple. Easily accessible filters make cleaning simpler, and high-quality caster wheels won’t buckle or bend when put under the weight of a full water tank. 

Drainage Options

There are a couple of options when it comes to draining the water from your dehumidifier. Manual drainage involves removing the water tank when it’s full and emptying its contents. It can be inconvenient and time-consuming to do this multiple times per day.

What if you’re looking for a continuous drainage option? A gravity drain uses a drain hose connected from the unit to a sink or floor drain. It will ensure continuous drainage from the water tank, but only as long as the unit is placed in an elevated position from the drain, it’s connected to. This can limit your placement options.

A condensate pump is the most effective way of achieving continuous drainage while also having the flexibility to place your 70-pint dehumidifier somewhere that suits you best. 

Some units have an internal pump built into the system already. Otherwise, you’ll need to purchase a drain pump and pump drain hose, which can often cost between $100 and $300

Water Tank Capacity

The moisture removed from the air by a 70-pint dehumidifier is collected in a water tank fitted near the bottom of the unit. Most of the best dehumidifiers will have a float switch near the top of the water tank that will trigger the unit to turn off when the water reaches a certain level and needs to be emptied. 

The larger the water tank capacity, the better. A larger water tank is especially useful if you aren’t implementing a gravity-based drain or a drain pump since you won’t have to manually remove the water tank, empty it, and replace it into the system as often.

If your dehumidifier runs continuously, you could expect to have to complete this action 3 or 4 times across a 24-hour timespan with a smaller water tank

It’s also useful to have a higher tank capacity if you plan on using your dehumidifier in a place such as a basement, garage, crawlspace, or anywhere else that there may not be a constant human presence. 

If you don’t hear the automatic shut-off alert, it may be hours before you realize that your dehumidifier hasn’t been on. A larger water bucket means that the dehumidifier can operate for longer without switching off or having to be refilled for more effective dehumidification.

Noise Level

Most 70-pint dehumidifiers will operate at a noise level of around 55 decibels when running on their highest settings. That’s only about the same level of sound made by an electric toothbrush or coffee percolator, so noise shouldn’t be too much of an issue when choosing a 70-pint unit. 

Suppose you’re planning on using your dehumidifier in a living area or bedroom, where you’ll need a quiet unit so that it’s still easy to watch TV, talk, read, or sleep. In that case, consider one of the quietest dehumidifiers that can operate at below 50 decibels.


The best dehumidifier for you is one that comes with features that meet your specific needs. The following are some of the most useful and commonly sought-after by people looking to dehumidify their homes:

Auto Shutoff And Restart

The best 70-pint dehumidifiers will come with an auto-shutoff that will turn the system off if there are any issues or if the water bucket is full, so you don’t have to keep a constant eye on your unit. 

If you live in an area where a power outage is a common occurrence, a dehumidifier with an auto-restart function is a must since you won’t have to manually input all your settings again when resetting the unit and turning it back on.


A humidistat in a dehumidifier works like the thermostat of an air conditioner. It measures the relative humidity levels of the unit’s environment and automatically switches the dehumidifier off when these levels get too high or too low. 

Not only does this ensure you’re always getting a comfortable level of dehumidification, but by reducing power consumption, a humidistat saves energy and money off your monthly bills. 

Notification Lights

Most dehumidifiers have notification lights that tell you when to remove and clean a washable air filter so that mold doesn’t grow in the tank or when the water bucket needs to be drained so it doesn’t overflow. Some units also use an audible alert tone.

Operating Range

The optimum range to use a dehumidifier is a room temperature between 70℉ and 90℉. Anything below that will start to affect how many square feet even a high-quality dehumidifier can effectively dehumidify.

If you live in a particularly cold environment, say somewhere between 40℉ and 60℉, you should look for a 70-pint dehumidifier that is specifically designed to operate at such low temperatures.

Energy Star Certification

A 70-pint dehumidifier that’s Energy Star certified has met the highest energy efficiency standards set by the US Environmental Protection Agency (EPA). They save energy, using around 30% less than a unit that hasn’t been Energy Star certified, saving around 30% of the cost of your regular energy bills.

An energy-efficient dehumidifier that’s been Energy Star certified may cost more upfront but can save you a significant amount of money in the long run!

Wi-Fi Capability

Some of the best 70-pint dehumidifiers have built-in Wi-Fi connectivity, which is a great feature if you use other integrated smart home technology. It will let you control the dehumidifier conveniently using Alexa or Google. 


It’s important to check the terms of the warranty when choosing a 70-pint dehumidifier. Most models come with a 2-year guarantee, though this will vary from brand to brand, as will the parts included in this guarantee. 

Most units that are designed to be placed and used in living areas may be sleek, shiny, and stylish, but they may last a few years less than a more robust dehumidifier designed to be used in a basement or crawlspace. 

If you know that the cost of repair or replacement could be an issue in the future, consider taking out an extended warranty that can cover your dehumidifier for five years. 

Best 70 Pint Dehumidifier Reviews

I’ve reviewed and compared the top-rated 70-pint dehumidifiers, so you can quickly look at some of the best units available today. Here are my top-5 picks!

Best Rated 70-Pint Dehumidifier 2021

Kesnos PD245D
Editor’s choice
Check price on Amazon
Dehumidifies spaces up to 4,500 square feet
Auto shutoff and 24-hour cycle
Digital humidity readout

This powerful dehumidifier performs effectively and efficiently in even the highest of humidity levels. It’s great for larger spaces up to 4,500 square feet, removing 70-pints of moisture from the air per 24-hour day. 

Convenient extra features include a humidity sensor and an auto-shutoff that will power the unit down when the humidity level of a room reaches an optimum 30%-80%. You can just plug it in and let it do its job! An air filter ensures the air you’re breathing isn’t just dry but clean and healthy too. That makes it a great option if you have allergies or kids. 

The unit is excellent for almost any living space since it has a unique, stylish, and discreet design. This unit is also a very portable dehumidifier, with ergonomic handles and caster wheels that make moving it from room to room easy.

This design also makes the PD245D easy and simple to use. A digital LED display and control panel shows all the settings and readings you need in one convenient place. Options to select when the unit turns on and off, as well as the percentage of moisture you want to remove from a room, mean you can customize dehumidification to be exactly how you want it.

This was the best 70-pint capacity dehumidifier I came across when compiling these dehumidifier reviews, and I’d recommend it as an effective and affordable purchase to almost anybody.

Best 70-Pint Dehumidifier For Colder Environments

Runner up
Check price on Amazon
Auto defrost and frost sensor
Four operating modes
Adjustable fan speeds

This flexible and versatile dehumidifier is effective in medium-sized spaces of up to 4,000 square feet. While it uses more energy than other units and certainly isn’t the most energy-efficient option, its low upfront cost does make it an excellent cost-effective model.

There are multiple operating modes to choose from, including standard, raining, drying, and sleep modes. Raining mode is especially useful for achieving the desired humidity level in large rooms since it enables the unit to absorb more moisture for a specified period. 

Intelligent sensors monitor the relative humidity of a room, so the unit removes excess moisture immediately if it goes above a user-specified level. Smart digital controls allow you to set up the auto-restart, control fan speed easily, and set the 24-hour timer. 

Auto shutoff prevents the water tank from spilling over when it’s full, but it’s the auto-defrost feature that sets this unit apart. This feature will automatically recognize when the internal coils have frozen and defrost them. 

That makes it a perfect choice if you live in a particularly cold climate or plan on using your dehumidifier in colder environments like a basement or garage. 

What We Like:

  • Four operating modes
  • Great for mid-sized spaces around 4,000 square feet
  • Intelligent operation
  • Auto defrost and frost sensor
  • Low-temperature operation
  • Adjustable fan speeds

What We Don’t Like:

  • Not very energy efficient

Best 70-Pint Dehumidifier For Energy Savings

h0meLabs HME20031N
Runner up
Check price on Amazon
Turbo mode for increased fan speed
1.8-gallon water tank capacity
Good warranty

This dehumidifier is both Energy Star and UL certified, meaning it’s among the best 70-pint dehumidifiers for energy efficiency and safety. You’ll use around 30% less power than other units, so you’ll save around 30% of your monthly energy bills. You’ll also be doing your bit to protect the environment and reduce your carbon footprint.

The unit can operate in comfort, continuous, or turbo mode. Comfort mode sets a comfortable relative humidity level based on the surrounding ambient temperature, which is great if you live in an area where this temperature may fluctuate

Continuous mode saves money off your bills since the unit will turn off when it reaches a specified relative humidity, using less electricity. Turbo mode increases fan speed and is useful to remove the nasty odors associated with mold and mildew. 

The unit is quiet and has built-in handles and caster wheels that make it a great portable option for use around the whole home. If you don’t mind the slightly higher than average upfront cost, this unit is the best for energy savings in the long run. 

What We Like:

  • UL and Energy Star certified
  • Multiple operation modes
  • Turbo mode for increased fan speed
  • 1.8-gallon water tank capacity

  • Slightly more expensive

Quietest 70-Pint Dehumidifier

Midea MAD50C1ZWS
Runner up
Check price on Amazon
Auto-restart function
Auto-defrost function
Low price point

You may notice that this dehumidifier advertises itself as having a 50-pint capacity, but in fact, it’s a 70-pint model. That’s because a change to the US Department Of Energy (DOE) standards in 2019 meant dehumidifiers are now tested in more realistic conditions than before. Only these testing environments have changed- not the units themselves!

This unit from Midea comes with more extra features than many other dehumidifiers, including an auto-defrost function, continuous mode, a fully adjustable programmable timer, and a powerful turbo mode for increased air circulation. These allow you to remove excess humidity and excess moisture as effectively or efficiently as you like.

User-friendly electronic controls, a washable air filter, and an easily removable bucket mean humidity control and unit maintenance are simple and easy. An auto-restart means you won’t have to waste time inputting your previous settings in the case of a power failure. 

The stand-out feature of this dehumidifier, though, is the super-quiet operating noise level of just 49 decibels – quieter than your refrigerator! It makes it perfect for use not only in living areas where you’re watching TV, talking to family members, or reading but also for the bedroom and especially at night if you’re a light sleeper. 

It may not be the most advanced or efficient dehumidifier in my review, but its competitively low price point and quieter than average operation make it very worthy of your consideration.

What We Like:

  • Auto-restart function
  • Auto-defrost function
  • Quiet operation
  • Washable filter
  • Low price point

What We Don’t Like:

  • Some reports of quality control issues

Best 70-Pint Dehumidifier For Basement

Aprilaire 1803Z
Runner up
Check price on Amazon
Great for basements or homes up to 3,800 square feet
Includes long garden hose for drainage
Heavy-duty dehumidification

This heavy-duty dehumidifier can operate with a powerful moisture removal rate of 300 cubic feet per second. That’s enough to quickly remove moisture from the very damp rooms of an entire home of up to 3,800 square feet.

Even so, the Aprilaire 1803Z is best used in basements, crawl spaces, garages, or any other space without much human traffic. Its design isn’t the most aesthetically appealing, but then it isn’t supposed to be. This unit is made entirely with power and durability in mind, so it will perform in even harsh conditions. 

It’s significantly heavier than most other units at 68.25 pounds, so it’s far from being a portable dehumidifier. It needs to be installed in your basement or crawlspace, and since it doesn’t use a water tank, it will need to be set up directly above a drain or connected to a pump, which isn’t the most convenient solution for some. 

While it doesn’t come with some of the extra features of other dehumidifiers, and it’s certainly more expensive, I’ve found it to be highly effective when used in a basement or crawl space

What We Like:

  • Heavy-duty dehumidification
  • Energy Star rated
  • Great for basements or homes up to 3,800 square feet
  • Includes long garden hose for drainage

What We Don’t Like:

  • More expensive than other units
  • Heavy at 68.25 pounds

70 Pint Dehumidifier: Frequently Asked Questions

How Much Water Does A 70 Pint Dehumidifier Remove?

A 70-pint dehumidifier can remove 70 pints of water from the air every 24 hours

How Much Power Does A 70 Pint Dehumidifier Use?

Dehumidifier power usage can generally be considered low, and the average power consumption is 700 watts, about the same as your refrigerator. Units certified by Energy Star will consume around 30% less power than the average.

Should You Run AC And Dehumidifier?

An AC unit can lower the air temperature of a room but is unable to remove moisture from that air. A dehumidifier may make a room feel more comfortable by removing humidity, but it cannot lower the temperature noticeably. In this way, an AC and a dehumidifier balance each other out, and I’d recommend using both for maximum effect.

How Often Should I Clean By Dehumidifier?

A dehumidifier should be cleaned at least once every 3 weeks to ensure it’s operating to its full potential and stop mold and mildew growing inside the unit.

My Final Thoughts

There are some great 70-pint dehumidifiers available for you to buy today. I hope that my reviews of some of the best and my buying guide have helped you feel that you make a well-informed purchase.

I love the Kesnos PD245D since it’s a complete package of effectiveness, efficacy, and affordability. It’s a perfect solution to dehumidify all kinds of spaces up to 4,500 square feet. Units from Midea, h0meLabs, and Airplus all have their unique benefits, while the robust and heavy-duty 1803Z from Aprilaire is perfect for basements and crawlspaces.
