, , Leave a comment

Is your house smelling rather musty, are you having trouble ventilating your environment, is your furniture clammy, are you having respiratory issues or are there damp spots on the wall? If one or all of the above sound like a familiar situation to you, there’s a pretty big chance your home is too humid. Luckily, a house dehumidifier is a great product to solve issues with unhealthy humidity inside your home. The best dehumidifiers are able to intake a lot of air, filter filth, dust particles, and subsequently, cool the air. A dehumidifier will produce steam that will in turn condensate to water vapor. This water is being stored inside the dehumidifier and the machine returns clean and dehumidified air back into your environment. As you might expect, air dehumidifiers come in all kind of sorts and sizes and some even have pretty nifty and advanced features as well. The best dehumidifier on the market will feature a combination of a good price point and decent horsepower but subtle characteristics such as the design and noise production can certainly come into play as well.

In the end – the best dehumidifier will depend on your personal preferences and the size of the area you’ll be using it in. We’ve reviewed six of the most popular and top-rated dehumidifiers on the market and discuss them in detail in the dehumidifier reviews below. But before we jump into the products themselves and provide a handy comparison, let’s take a look at how air dehumidifiers work and how they can benefit both the health of your house and your personal health.

What do dehumidifiers do?

What is a dehumidifier? The concept of an air dehumidifier is pretty simple and can serve two purposes. By extracting an excess of moist in the air, it effectively makes air dryer while cleaning it at the same time. An air dehumidifier sucks up a certain amount of air and uses a cooling system to make it significantly colder to the point where the air will condensate. Water drops are formed and stored in a reservoir via a drain hose. Air dehumidifiers are versatile and can be placed anywhere: a living room, bedrooms or even the basement as those usually have a high humidity rate. An added bonus is that the water that’s being stored is clean and distilled, which is perfect for use in home appliances such as a steam iron.

At the end of the cycle, the air dehumidifier blows the dry air back out. Air dehumidifiers are often equipped with a filter that intercepts all kinds of dirt, dust and other unhealthy particles – as you can imagine that provides a substantial improvement to the air quality. The water container will need to be emptied, but there’s no need for worrying about using a dehumidifier too much, the machine will just shut itself down in case the reservoir is full.

What are the practical effects of an air dehumidifier?

If the percentage of humidity in your house is too high, it can cause some serious issues and damage – fighting this excessive moist with an air dehumidifier is the only solution. An average and healthy humidity level would be anywhere between thirty and sixty percent. When the percentage starts climbing above 60%, it’s going to have very noticeable negative effects.  An air dehumidifier can help with any of the following:

  • A weird, stale or musty scent
  • Clammy furniture
  • An excessive or unusual amount of silverfish in the house
  • The occurrence of mold on the walls
  • Rising damp on the walls

An air dehumidifier is also a fantastic aid if you’re dealing with minor breathing issues or if you seem to catch a cold more than you’d like. Or perhaps you’re sensitive to allergies? The cleaning nature of an air dehumidifier provides more comfortable air for breathing in. Speaking of comfort, there’s another important aspect of air dehumidifiers that is often overlooked: it can help with dealing with the heat and improving the airflow of your air conditioning system. A high humidity reading and high temperatures can often go hand in hand and their negative effects are certainly worse when the two elements are combined. Luckily, if you reduce the humidity in the air, you’ll also reduce the effectiveness of heat. Although the usage of a dehumidifier might not make a major difference in actual temperature, it helps with the chill factor and comfort. Another direct result of less humid air is that air conditioning will operate more effectively.

What to look for when choosing an air dehumidifier?

Aside from dehumidifier prices, design and sound production (a quiet dehumidifier is always a pleasure as it isn’t likely to disturb other sounds in the house), there are other major aspects of an air dehumidifier that need to be considered. First of all, and probably the most important specification of an air dehumidifier is the coverage in square feet or meters it can provide. The strength of an air dehumidifier is usually rated in pints. If you choose one that is rated for a smaller area – chances are it’ll take a long time before it can prove its effectiveness or won’t be able to get the air humidity down to an acceptable level. Usually, air dehumidifiers will be able to extract anywhere from 30 to around 70 pints of moist in the air in 24 hours.

Another thing to factor in is the capacity of the water reservoir. Granted, the capacity isn’t really a major issue if you replace it often, but you’d be surprised with the amount of water that can be extracted from the air you breathe in sometimes.

Differences between whole house and portable dehumidifiers

Air dehumidifiers come in two major sizes and types: whole house dehumidifiers and portable dehumidifiers. Areas that are continually moist benefit from powerful systems that are less portable, but are able to cleanse the air of excessive air continuously, although most portable systems are definitely up for the task if the moist isn’t too excessive. Although these situations can vary, portable dehumidifiers are usually the best option for most, provided they’re powerful enough.

If you’re dealing with major humidity issues in multiple locations in the house, it might be worth considering a whole house dehumidifier. You can also directly implement and integrate it with your heating, ventilation and air conditioning (HVAC) system. These are usually equipped with a pump.

Is an air dehumidifier luxury or a necessity?

An air dehumidifier might be considered as a luxury or gimmick item for some, but considering that moisture is very easily created in a home, it’s definitely a product that serves its purpose – especially if you consider that a too high humidity level causes serious problems with house and health. Insects, silverfish, and other nasty bugs thrive in humid regions as well as pollens and fungi. Reducing the moisture simply reduces these as well. Basements are usually extremely sensitive to moisture, so it can be important to find the best dehumidifier for basement usage as well.

It’s not something you often think about, but moisture can come from pretty much anywhere. Did you know that an average family creates up to 30 pints of moisture every day? The breathing cycle of humans is a major contributor to moist, but don’t forget to factor in elements such as bathing, showering, drying and cooking. Worst of all is that moist can be absorbed into pretty much any object, some with more devastating effects than others. In short, air dehumidifiers are extremely useful for multiple purposes.

Without further ado, let’s take a look at our six top picks for air dehumidifiers. We’ll compare dehumidifiers and stack them up with the competition so you can make a thorough and well-researched choice.

Frigidaire FFAD7033R1 70-pint Dehumidifier with Effortless Humidity Control Review

Frigidaire is a well-known brand when it comes to air dehumidifiers and with good reason: the company produces decent devices with a clean, subtle design and user-friendly interface. The Frigidaire FFAD7033R1 is without a doubt Frigidaire’s most popular air dehumidifier – a great reason to check and see if the FFAD7033R1 can live up its big expectations. At the time of writing you’ll pay a little above $200 for this air dehumidifier, but be sure to check out the actual price over here.

In terms of specifications, the Frigidaire FFAD7033R1 is a rather powerful device and its rated at 70 pints per day. In other words, the machine certainly packs a lot of power and will have no issues cooling down plenty of air. The water reservoir has a capacity of just above 13 pints. That doesn’t seem overly large, but luckily Frigidaire has equipped the system with a full tank alert feature that warns you plenty of time ahead when it’s time to clean the container. There’s also a splash guard and auto shutoff feature built-in. Fun fact: the FFAD7033R1 is a revised version of the Frigidaire FAD704DWD which performs roughly the same and has built up quite a positive reputation among critics and buyers.

Frigidaire likes to humblebrag about its Energy Star Certificate and with good reason: the FFAD7033R1 is a power efficient device and operates at a low temperature of around 41 degrees in order to save energy. This efficiency also ensures a very silent operation, the Frigidaire FFAD70333R1 is a remarkably quiet air dehumidifier. It won’t impact the daily routine of the house at all and if you put in the living space, you probably won’t even notice it’s there. It generally won’t go any higher than 58 decibels on the highest fan setting at a very small distance. Annoying sounds such as rattling or coil whine also don’t occur, you’ll just be hearing the fan spinning. And even if you’d rather don’t have any noise at all, you can schedule the Frigidaire thanks to a digital humidity readout on the display and a timer function. Unfortunately, the timer function doesn’t allow for extensive pre-programming of the device to run daily at certain intervals for example.

The Frigidaire FFAD7033R1 is a portable system, and that also shows in its design. There are plenty of handles (including a very sturdy top handle) and wheels at the bottom of the device to quickly and easily set it up in another room. With a weight of around 47 pounds, those wheels can certainly come in handy. Dimensions of the FFAD7033R1 are 11.6 x 15 x 24.4 inches. As you can see, this isn’t the most compact air dehumidifier in the world, but it packs and an impressive amount of power in a relatively small package. Aside from the handles and wheels, the FFAD7033R1 has some built-in cable management as well so you can quickly wrap the power cord around and out of sight.

One of the most important pros of the Frigidaire FFAD7033R1 is its excellent display and user interface. The front panel has a very no-nonsense design and is extensive while being fairly simple in operation. Aside from the usual power button, you’re also able to toggle fan speeds, set a humidity target or set timers. The filter needs cleaning or the water reservoir needs to be emptied? You’ll be notified with a blinking red light. There are no complicated settings or unnecessary LEDs but an interface that just works – what more could you ask for. If you’re not a fan of reading manuals, you’ll certainly learn to appreciate this Frigidaire’s interface.

Versatility is another major benefit of this air dehumidifier. Aside from portable use, you’re also free to install the Frigidaire FFAD7033R1 near a suitable drainage system so that the device can operate continuously. When using this feature, the drain can be rather sensitive however and it might require some tinkering during installation. It’s only a one-time issue but is worth mentioning nonetheless.

In short, we’re a big fan of the Frigidaire FFAD7033R1 and we can certainly understand it’s success and appeal. Buyers definitely agree: With an average user review score of 4.4 stars out of 2810 reviews on Amazon, it’s safe to say that this air dehumidifier is extremely reliable and provides a very satisfactory result.


  • Reliable operation
  • Nice, relatively compact design
  • Easy to carry around
  • Portable and permanent modes
  • Energy efficient and operation on a lower temperature
  • Powerful
  • Great interface
  • Fairly quiet


  • Generally, a tad more expensive than other 70-pint air dehumidifiers
  • Doesn’t allow for more complex programming tasks
  • Installing a drainage hose might require some tinkering

Hisense 70 Pt. 2-Speed Dehumidifier with Built-In Pump Review

This Hisense 70 Pint dehumidifier is also known by its slightly less catchy name, the Hisense DH-70KP1SLE and features a built-in pump that can automatically pump all the collector moisture back into your home via a sink and a garden hose. In other words, there’s no need to empty the water reservoir – although you can certainly choose to do so if you don’t have options for a pump in your house. The pumping process is extremely straightforward: simply press the ‘pump’ button at the top of the machine and you’re all set. This Hisense dehumidifier also comes with most if not all of the accessories necessary to set up a continuous drainage system. This would be considered the best dehumidifier for basement use if you have the possibility to drain the water, although the large water bucket definitely helps too.

As the name suggests, this Hisense air dehumidifier can handle up to seventy pints per day and is one of the stronger systems on the market. Even though this dehumidifier has excellent drainage solutions thanks to the built-in pump, the water collection bucket remains fairly large with a capacity of 16 pints. If you’re not planning to use the pump feature, feel free to check out the Hisense DH-70K1SDLE which features the exact same internals, only without a pump and a lower price tag.

Although Hisense isn’t advertising a particularly low energy consumption, the 70KP1SLE scores well above average in this aspect. The usual amount of power consumed will be around 610 watts in a 50% humid environment. If power consumption is a major selling point for you, you won’t be disappointed by the Hisense’s efficiency. Noise production is a working point for this air dehumidifier as it can go towards 67.5 decibels at a close range, although the auto and low fan speed settings perform much better in this regard.

One thing that certainly strikes out is the fact that the Hisense 70 Pt. 2-Speed Dehumidifier has an excellent hygrometer. In other words, it does a splendid job of measuring the humidity of an environment with great accuracy. In fact, the margin of error is just about 1%.

Compared to some of the other dehumidifiers in this round-up, the actual moisture removal performance can be mixed. It can take a while before an area is dehumidified and although it certainly does the trick, others such as the Frigidaire above simply do it quicker. The difference usually is never greater than 25% and chances are you’ll probably not notice in daily usage, but if you can appreciate quickness, it might be worth considering another dehumidifier.

We’re really fond of the extensive options to customize the working of the Hisense to suit the needs of your home. As you can expect there’s a timer function that works pretty well in half-hour intervals. The auto fan speed option is a great choice if you just want to install the air dehumidifier and forget about in a manner of speaking, as it does a pretty decent job of balancing power and sound production. The system also has a built-in auto mode that will automatically run whenever the humidity reaches a certain value. It’s fairly programmable and its adjustability certainly shines.

This dehumidifier looks great as it uses a two-tone exterior with a rounded and sleek look. Build quality is average, but the device certainly doesn’t feel too cheap. Dimensions are rather standard with 15 x 14.4 x 24.7 inches and the device weighs in at 46.2 pounds.

The price point of the Hisense DH-70KP1SLE is in line with other 70 pint dehumidifiers at around $230.


  • Looks great
  • Excellent programming and adjustability options
  • Large water capacity
  • Built-in pump for continuous, no-hassle use
  • Extremely accurate hygrometer


  • Mediocre performance
  • Can be too loud at high fan setting

Frigidaire 50-Pint Dehumidifier with Effortless Humidity Control Review

Another product from Frigidaire, and it’s actually a smaller sibling of the Frigidaire 70-pint model we’ve discussed above. The internals of the device are extremely similar and this 50-pint dehumidifier comes with all the features and functionalities of the larger 70-pint version.

Instead of thoroughly going over all this smaller Frigidaire has to offer, we’ll take a closer look at some of the differences. Although this model is rated for a smaller amount of pints, it uses the same exterior shell and isn’t more compact compared to the larger version. That does seem like a missed opportunity, as some might prefer a small and unobtrusive design. However, energy consumption is significantly lower. As you might expect, the performance isn’t on par with the larger 70-pint dehumidifiers, but it’s perfectly acceptable for smaller to medium-sized rooms. This Frigidaire certainly competes for the title of best 50-pint air dehumidifier in terms of both performance and functionality.

The Frigidaire 50-pint Air Dehumidifier usually retails for less than $200 and its price tag comes dangerously close to the 70-pint version. Unless the price difference is more significant or if you just really don’t need a 70-pint dehumidifier in your house, choosing the beefier version would be the best option.

Friedrich D70BP 70 Pint Dehumidifier with Built-in Drain Pump Review

If you envision an air dehumidifier, the Friedrich D70BP is certainly a device that can match your expectations. It’s rather bulky and comes with a slightly boring design, but features extensive options and has a built-in pump. We’ll say it right out of the gate, this Friedrich D70BP is definitely more expensive than the other dehumidifiers in this buyer’s guide. If you’re not interested in extensive features or the pump, it’s best to choose a less expensive model. If those things sound like music to your ears, be sure to continue reading.

The quite ‘boring’ exterior of the Friedrich D70BP is also translated into the specifications of the air dehumidifying unit. Performance is slightly below average compared to other 70-pint systems, but still manageable. Although energy consumption isn’t alarmingly high, it’s not great either. The same can be said regarding noise output – it’s not the quietest model around.

So what makes the Friedrich worth considering, you might ask?

First up, it’s immediately noticeable that the D70BP features an excellent build quality – a very distinct difference compared to other dehumidifiers. The shell is very durable and it luckily isn’t much heavier than other systems at around 42 pounds. The interface at the top of the device is somewhat hidden but works great. Another benefit of the Friedrich D70BP is its excellent warranty handling (A year + between 2 and 5 years for the sealed system) and customer service, as many users have pointed out.

Options for water collection are excellent with a large capacity water tank up to 16.2 pints and thanks to the built-in pump, you can also get rid of the collected water instantly. The drainage operation is also splendid and the D70BP even comes with a second hose. We haven’t discussed the humidity range of other devices as they are all in the lines between 35 and 80 percent relative humidity, but the Friedrich takes it up a notch. It can be set anywhere between 30 and 90%, which is remarkably versatile for a dehumidifier. The dehumidifier also comes with a defrost functionality, which can be useful in the case that frost is (accidentally) formed.


  • Great humidity range
  • Superior build quality
  • Good warranty handling
  • Excellent built-in pump


  • Expensive
  • Doesn’t perform as well as the competition
  • Can get quite loud

Keystone KSTAD50B Energy Star Dehumidifier, 50-pint Review

The Keystone KSTAD50B is one of the least expensive dehumidifiers on the market, but it certainly doesn’t mean that you get a sub-par product. In fact, price-performance wise, the Keystone KSTAD50B is hard to beat.

That’s mainly because it does a lot of things right. The Energy Star certificate certainly comes in handy, because energy consumption is fairly low for a 50-pint dehumidifier and it will have a hard time surpassing 440 watts in usage.

While the KSTADB50B may not be the quietest dehumidifying solution on the market, the working remains practically inaudible. Even when using this dehumidifier with a high fan speed, it won’t go above 52 decibels at a normal, short distance.

So far, we’ve got above average energy consumption and a silent operation, so that must surely mean that its performance lacks, right? Luckily, Keystone managed to prove us wrong. Analog to its performance in energy efficiency and noise, the KSTAD50B performs above average when it comes to moisture removal. It won’t break any speed records, but it’s certainly more than sufficient for normal, 50-pint use. Another major pro is that the Keystone comes with a built-in defrost functionality, something that is even omitted on (much) more expensive models.

Although the dimensions of the Keystone air dehumidifier aren’t particularly compact at 15.4 x 10.8 x 23.2 inches, its weight certainly makes this one of the best portable dehumidifiers on the market. You can easily carry it around; the KSTAD50B weighs in at just above 36 pounds.

Now, we’re not saying that this product is perfect. Due to the lighter materials, build quality is rather mediocre. The water tank is definitely on the smaller size at 10.4 pints. That means you’ll have to replace it more often. Furthermore, installing a gravity drainage system will require you to install a separate adapter and screw it onto the device. Although this is a one-time thing, we’ve seen more user-friendly solutions.

Nevertheless, the Keystone KSTADB50B is one of the best 50-pint dehumidifiers on the market. Performance is great and the price tag is remarkably on the lower side. In terms of the most bang for the buck, this one is very hard to beat.


  • Performs well above average in overall performance
  • Great power consumption
  • Very silent
  • Can easily be carried around
  • Built-in defrost functionality


  • Build quality isn’t great
  • Gravity drainage requires tinkering to set up
  • Small water container

Whynter RPD-702WP Energy Star Portable Dehumidifier with Pump, 70-pint

If you’re looking for a strong 70-pint dehumidifier with a pre-installed pump, the Whynter RPD-702WP might definitely be worth considering. This Whynter dehumidifier certainly doesn’t have striking or modern looks, but it does the job just right. You do have the ability to choose between the regular White color option or a Slate Grey version, although the latter is a bit tougher to find and can be more expensive.

The performance of the RPD-702WP is on par with other 70-pint dehumidifiers and is definitely good for its price point. Efficiency is also very good and it weighs surprisingly little considering this is a larger 70-pint dehumidifier at only 38 pounds. Unfortunately, noise production is a bit on the higher side with measurements of around 58 decibels with the high-speed fan setting. However, it is perfect for places where an annoying sound isn’t really an issue such as in basements. Furthermore, the automatic defrosting feature does a splendid job at preventing the buildup of ice.

Thanks to the pump, you’re able to utilize a completely automatic water drainage system for a no-hassle experience. And if there’s no drainage option, Whynter has got you covered with a really generous water tank capacity of 18 pints.

Another thing that we noticed is that the Whynter RPD-702WP can work in a large humidity range between 30 and 90 percent relative humidity. The control panel at the top of the dehumidifier is also very simple and easy to use and features a number of options for the timer. It’s not extremely programmable but will do the trick in most cases.

In short, the Whynter RPD-702WP is an inexpensive and reliable 70-pint air dehumidifier with a built-in pump that performs well but could be a bit quieter.


  • Great performance for the price
  • Energy efficient
  • Large water tank capacity
  • Water pump works well
  • Automatic defrost
  • Wide humidity range


  • Control panel isn’t very programmable
  • Features a rather boring and outdated design
  • Can produce quite some noise at the high fan speed setting

Conclusion – The Best Dehumidifiers

As you’ve seen above, air dehumidifiers come in all sorts of sizes and features. The first thing you need to ask yourself when purchasing one is whether you’ll go for a 50- or 70-pint model. Also, think about whether you want to install the dehumidifier to a drainage system – definitely grab one with a built-in pump if that’s the case, but you can definitely save a few bucks and choose one without a pump if you’re not planning on using it.

Out of our six top-rated dehumidifiers, we’re a big fan of the 70-pint Frigidaire FFAD7033R1 as it provides an excellent balance of price-performance, features, and a sleek design. If you don’t need the power that a 70-pint air dehumidifier generally provides, it’s worth checking out the smaller 50-pint sibling as well – but only if the price is right.

When it comes to smaller 50-pint models, the Keystone KSTAD50B is really hard to beat. It features excellent performance and functionality for the price, and the fact that it’s the cheapest product in our comparison and features a defrost function is remarkable – a great all-around option and a bit of a jack of all trades.

Regarding dehumidifiers with pumps, go for the Friedrich if you want a dehumidifying system that’s extremely reliable, is built very sturdy and provides a very satisfactory auto drainage experience. Though it is definitely expensive, and both the Hisense 70 Pt and the Whynter RPD-702WP score better in almost every performance aspect while being much cheaper. The Hisense is a great option for general use and features excellent adjustability options, while the Whynter has a very large water container and performs slightly better.
