2017 Dehumidifier Reviews: Best Dehumidifier For Home Use And Basement

Do you have a basement in your home? Well, that cool and damp unpleasant smell is actually mold and mildew caused by too much moisture in the air. If you can detect a pungent odor, you probably need an effective dehumidifier. Take action. The growth of mold can be extremely damaging for your home and your health. Buy the best dehumidifier, say goodbye to excess moisture and safely reduce the humidity to proper levels.

Once the humidity level is below 50%, the space will seem fresher. At last, you can put your stored possessions and paperwork in the basement without having to worry about mildew. Along with the musty smell, there are other common warning signs for humidity. Look for condensation on the floors and walls. Be watchful for any physical presence of mold. When mold spores become airborne, this can impact negatively on your respiratory system and trigger asthma attacks or allergic reactions.

The dampness from excessive moisture can cause the foundation and walls to rot. This leads to structural damage and the risk of health problems.

We will help find the right dehumidifier for your basement. Get rid of excess humidity once and for all. You need the right equipment for the job.

So, let’s first explore the basics.

Find out what you should know before buying a dehumidifier…

How does it work?

A dehumidifier helps to remove moisture from any space and makes the air drier. The moisture in the air is sucked into a grill as the electric fan draws the air through the evaporator and turns it back into liquid. This liquid is then collected in the water tray.

The remaining air is then sucked through the heater to warm up the space.

What’s inside a dehumidifier?

Dehumidifiers are pretty standard in their build. Their parts are basic:

  • Fan
  • Water tank
  • ​Compressor
  • Coils

Some models include an added air filter as well.

Harmful effects of Humidity

A humid environment is the ideal place for microscopic organisms and bacteria to grow.

Mold and mildew spores thrive in humid conditions. They can then become highly toxic when they enter your body.

Dust mites can also be a serious issue if you suffer from allergies and asthma.

Bottom line: bacteria absolutely love humid spaces. Being exposed to mold growth can cause you to get sick more often and result in general poor health.

Popular Symptoms of Allergies

  • Stuffy nose
  • Itchy, watery eyes
  • Skin rashes
  • Difficulty breathing

You may notice an unusual smell coming from the clothes, purses or shoes in your closet. When a kitchen or bathroom has little to no ventilation, the humidity will raise and cause bacteria to develop quickly.

Benefits of a dehumidifier

We can see humidity in the steam coming from a hot shower, a sauna or even outside on a foggy day.

Indoor humidity leads to many health risk and problems in the home. It’s wise to safely lower the levels with a dehumidifier. Don’t take a chance when it comes to your wellbeing.

Humidity can affect electric equipment like the TV or computer. It can also create mold in living spaces. This is harmful to your health as it can lead to respiratory diseases.

Another benefit of a dehumidifier is in reducing dust without the hassle of cleaning so much.

Creating dry hair also helps with the air conditioner. The AC won’t need to work as hard at removing moisture and cooling the air. With the dehumidifier, your air conditioner only has to create cool air.

What features does a basement dehumidifier require?

It is important for a dehumidifier to be able to work in lower temperature environments. Basements are usually cooler than the rest of the areas in the house while covering a large amount of floor space.

Dehumidifiers for the basement must be capable of extracting 100% of the moisture in spaces of at least 2,000 square feet.

Here are some important features we should consider…


The dehumidifier must have appropriate removal capability along with the right coverage for the size of your basement. The bigger the area, the better is it to have a larger capacity dehumidifier.

Water Collecting Tray

Since the dehumidifier is working to control moisture, it is important to know where that water will go. Consider the capacity of the product as well as its volume.

If you do not want to spend lots of time emptying the tray, it’s essential to choose a model built to keep this annoying task to a minimum.

If you plan to pop your device in the basement, a hose connection will direct the vapored water straight to the drain without needing a tray. If your home does not have a drain, a simple pump will be sufficient to send the water to the sink or any drains through the window.

Auto Defrost

This is used to prevent the coils from freezing while allowing the dehumidifier to continue removing moisture.

Low temperature Operation

Dehumidifiers with low temperatures are ideal in cool climates as they will continue to draw moisture out.

Humidistat/Built-In Hygrometer

This allows you to set the precise humidity level you require.

Continuous Drain Option

This will ensure that the dehumidifier will continue to remove excessive moisture without the stress of repeatedly emptying water buckets.

Automatic Restart

This feature is useful when it comes to a power outage. Your dehumidifier will restart as soon as the power is restored.

Automatic Shut-Off

For dehumidifiers that don’t offer a draining option, make sure it has an auto shut-off. This will help to prevent overflowing.

If the water tray gets full, the machine will automatically shut off to protect the machine and reduce the risk of water overload.


A timer is ideal and can come in very handy if you tend to forget that your dehumidifier is on. It will also lessen your electricity bill as the rates are lower at certain times of the day. You can run your unit during these periods to save money.

The device will easily turn back on after a power outage. It will also switch itself off when you are out. This is another great money saving feature since the longer the machine runs, the more energy this device uses.

User-Friendly Settings

Search for models with wheels to enable easy maneuverability. Also look out for products with easy-to-read settings and dials.

Dehumidifiers with digital settings are generally simple to read and understand.

What to look for in particular?

Think about exactly how and where you will use your dehumidifier.

Make sure to study user reviews that highlight performance, ease-of-use, warranties, and other key information.

Knowing the size of the space and the amount of moisture you want to remove is important. This will determine what type of dehumidifier is the best fit for your needs.

For large floor coverage, you will need a high-capacity dehumidifier that will remove at least 70 pints of water vapor in a day. Make sure not to purchase anything smaller as it will prove false economy.

Check the manufacturers’ list to get a proper estimate of the minimum and maximum footage the model can manage.

best dehumidifier in 2017

Below, we have listen the top 9 dehumidifiers.

Dehumidifiers vary wildly in terms features and sizes. This can make the buying process rather confusing. We’ve done all the research for you to make that decision a whole lot easier.

1. Ivation 70-Pint Energy Star Dehumidifier - Best Dehumidifier for 2017

best dehumidifier

This dehumidifier from Ivation is very well-constructed, and can handle a space as large as 4,500 square feet. It comes with an array of convenient features, and boasts a sleek design that is user friendly in many ways. It’s perfect for those who need to control air moisture in larger spaces, while also being able to program it to exact settings.

Notable Aspects

Ivation designed this dehumidifier to truly be a plug and play unit. It’s auto features allow for you to turn the unit on, while it calculates the humidity and cycles on and off accordingly. The digital display is easy to use and understand, and provides you with real-time updates, while also giving you control over all the unit’s different modes and settings.

Speaking of settings, you have plenty to choose from here. Customized humidistat programming, fan speed, and 24-hour timer capabilities are all easily available. There’s even a frost sensor that protects your coil and prevents the unit from freezing up in colder temperatures. Auto-restart saves your settings even after it’s been turned off, or if there is a power outage.

Moving the unit is an easy task thanks to solid metal casters and a built-in handle. The reservoir holds up to 1.3 gallons of water, so you can leave it on for extended periods without having to worry about constantly dumping it. Weighing in at just around 40 lbs, this Ivation dehumidifier is on the lighter side, so moving it to storage or to different parts of your home shouldn’t require too much effort.

Negatives: Unfortunately, while the unit does have the ability to host a hose connection for continuous drainage, there isn’t a pump to push the water through. If you want to keep the unit draining at all times, you’ll have to place it on a higher level.


  • Handles large spaces
  • Easy-to-use controls
  • Easy to move
  • Lightweight
  • Works in low temperatures


  • No pump for continuous drainage


Ivation has clearly put a lot of time into considering all of the various aspects and features a quality dehumidifier should have. Whether it’s retaining programmed settings, ease of transport, storage amount in the reservoir, or the washable filter, this unit is one of the most efficient and simple dehumidifiers on the market, meeting and exceeding the criteria for us to rank it as the best.

2. Frigidaire FFAD7033R1 70-Pint Dehumidifier with Effortless Humidity Control - Good for Basements

best dehumidifier

Frigidaire is a renowned name in home appliances, and this dehumidifier displays much of the quality and ingenuity the company has become known for, while still being affordable. Programmable settings and superb energy efficiency make this unit perfect for prolonged periods of consistent use. The loudness of it makes it better suited for areas such as basements, however.

Notable Aspects

The first thing you’ll notice about this particular unit is the sleek look it provides. The controls are located on the top, as is the carry handle. An LCD screen provides all of the unit’s information, as well as the numerous controls and settings. At just over 40 lbs, this unit is quite easy to transport.

This dehumidifier is Energy Star rated, so it features a high electric efficiency that can save you plenty of money on your utility bills. This unit is designed for consistent use, so the eco-friendly rating will go a long way in keeping bills down if you use it year round. If you are needing a dehumidifier to leave running in your basement, this should be at the top of your list.

Like most high-quality units, this dehumidifier includes a reusable filter that can easily be rinsed off every so often. The filter’s fine material catches a number of impurities, while also trapping in mildew and mold. A few quick rinses and scrubs in the sink will have the filter good as new in a matter of minutes.

A frost sensor gives the unit better operation in cooler settings, while also preventing the cool from being damaged.

Negatives: This isn’t the quietest dehumidifier around, so if sound is an issue for you, you’re going to want to steer clear of this one. The volume makes it better for rooms or parts of your home that you won’t be spending a lot of time in, such as the basement, or an enclosed crawl space.


  • 70-pint daily threshold
  • Energy Star certified for lower electric bills
  • Vibrant LCD screen with status indicators
  • Cleanable filter
  • Frost sensor
  • Light and easy to carry


  • A bit on the loud side
  • No pump for continuous draining


This unit’s solid construction and innovative features make it incredibly easy to use for just about anyone. The energy efficiency aspect is a big one, as the unit could end up saving you hundreds of dollars per year in utility costs, basically paying for itself. The high 70-oint removal amount and large capacity reservoir make it great for using consistently, but you may want to relegate it to the basement.

3. Friedrich D70BP 70-Pint Dehumidifier with Built-In Drain Pump

The previous two humidifiers we’ve reviewed lacked a pump that can push the water out of the drain tube. This unit from Friedrich takes a different route, with its built-in pump that makes this one of the best continuous use dehumidifiers around. If you need a unit that you can turn on and leave on its own, this dehumidifier has got you covered.

This Friedrich D70BP is appropriate for spaces up to 2,500 square feet, and offers rates of 25, 50, and 70 pints removed from the air per 24 hour period.

Notable Aspects

The Friedrich D70BP displays a minimal aesthetic that allows for it to easily blend in with most decor, which many will appreciate. Controls are centrally located, with an interface that is deciphered in a matter of moments. Set-up is quick, with the unit ready to go after plugging it in.

The most notable feature here is going to be the continuous drain pump. All you need is your own hose that can attach to the back, which is then routed anywhere you’d like -- to a sink, drain, window, wherever.

The pump can push water a total of 15 feet in any direction, so you have lots of leeway as far as deciding where to place it. This is a big advantage.

For those that wish to use the reservoir tank instead, the 16 pint capacity provides plenty of time in between drainings. Once the reservoir is full, lift out is easy.

The Friedrich D70BP is Energy Star compliant, so you know you’re getting peak energy efficiency and lower electric bills. This is the perfect pairing with the unit’s continuous drainage capability, as you’ll likely have it running mostly non-stop during peak months.

Negatives: The price of the Friedrich D70BP is a little steep. The unit’s energy efficiency and drainage features help offset the price a bit, but there are several who will look for a cheaper unit. The lack of a carrying handle makes the dehumidifier more difficult to move around as well.


  • Very versatile
  • Drainage pump with excellent range
  • Energy Star Compliant
  • Modern design
  • Customizable settings


  • High price
  • Hard to transport due to lack of handle


The Friedrich D70BP may cost more than other units, but the features will be worth it to those who don’t want to worry about emptying a reservoir every day. While other units usually have a drainage hose, the pump power of this unit makes continuous draining much more feasible and easier to accomplish regardless of where you set it up.

4. BLACK+DECKER BDT70WT 70-Pint Portable Dehumidifier - The Most Stylish Dehumidifier

Perhaps the most stylish dehumidifier you’ll come across, this unit from BLACK+DECKER backs up the looks with some impressive performance and features -- and for a great price. It is simple to use, and even includes a pump feature for continuous drainage.

Many buyers opt for this unit due to the brand name, which is definitely understandable, as BLACK+DECKER is a household name in tools and appliances. The major brand names allows for the price point, as well as better customer service, better quality, and the assurance of a good product.

Notable Aspects

As I’ve already noted, the first thing you’ll notice about this unit is the design. Very modular and minimal, making it versatile for any decor type, and maybe even an asset in some ways. The front is entirely blank, with a small window to view the reservoir. Digital controls are on top.

Set-up is easy. Just put the castors in, check the reservoir bucket, and you’re all good. You can choose from different fan speeds, turn a timer on, set your drainage type, all in a matter of seconds.

The unit works in a broad range of 54 degrees, in between 38 degrees and 92 degrees Fahrenheit. 70-pints per day is the standard amount for a unit this size, and this dehumidifier actually uses significantly less power than most space heaters, despite not being Energy Star rated.

The humidity gauge is widely considered one of the better ones around, so you can set it to a specific point with peace of mind, and without having to purchase a separate gauge to be sure of an accurate reading.

The included pump isn’t the strongest one you’ll find, but it’s still powerful enough to push the collected water through a short hose and out of a nearby window or drain. If you use the reservoir, you'll notice how easy it is to pull out and put back in.

Negatives: Despite not using a lot of power, this unit seems to run much hotter than others. If you use it in a smaller room or area that’s not a basement, you might need to run the air conditioner a bit more to compensate. The air intake of the unit is located directly on the back, so you can’t place it right up against a wall.


  • Looks great
  • Very cheap for the features and performance
  • Quieter than most units
  • Includes a water pump for draining
  • Accurate humidity gauge


  • Puts out a decent amount of hot air
  • Can’t be pushed against a wall


BLACK+DECKER have put out a great unit for a great price, regardless of any small annoyances such as the heat and air intake. You can set this dehumidifier up in any room without worrying about how it looks, or about how loud it is. For some, that’s all they ask out of one.

The pump is definitely a nice feature, and this unit is more than capable of drying out a large room or basement. Many have been surprised at its efficiency even when used in larger spaces. It’s hard to find a better unit for the price range.

5. Hisense 70-Pint 2-Speed Dehumidifier with Built-In Pump

best dehumidifier

Including a pump always gives a dehumidifier an upfront advantage over any others, a fact not lost by the people at Hisense. Although this unit is only for use in areas 1,500 square feet or smaller, it’s still a very capable dehumidifier that is simple in operation and features.

The price point is a big sell as well, so if you want a pump unit without paying too much, this is worth taking a look at. It’s features are bare-minimum in some areas, but the unit still does what it’s made for: remove air moisture.

Notable Aspects

Well, the pump is the first thing that comes to mind. Continuous draining is a big selling point for a dehumidifier, and the only way to do that without setting your unit up high with a hose running down is for it to use a pump. Hisense doesn’t state a specific limit on the pump’s range, but most would say around 10 feet, which isn’t as strong as some others.

If you choose to use the tank instead, you’ll be happy to know there’s an auto-shutoff that stops the unit when the reservoir tank is full. Tank removal and dumping is quick and easy.

The low temperature range of this dehumidifier makes its suitable for colder climates, or during cold times of year. As long as the room is above 38 degrees, the unit will function normally. It’s also worth mentioning that the noise level is relatively low, so you can use it in your home outside of the basement with minimal annoyance or interruption.

Negatives: There has been plenty of complaints about the pump breaking for this model. While there are a lot of factors that go into this happening, the pattern is hard to ignore. Obviously the unit will still work without a pump. Still, its’ best to minimize pump usage with this model. The 1,500 square foot coverage may be a bit small for some as well.


  • Very affordable
  • Built-in pump
  • Quiet operation
  • Low temperature friendly


  • Fragile pump
  • Cycles on and off frequently
  • A bit on the heavy side


Despite its flaws, this unit is a great unit for the price, as long as you know its limitations. The auto shut-off feature is vastly underrated, especially if you prefer to use a tank. The quieter compressor and fan will make this much more suitable for inside your home, especially when considering the 1,500 square foot threshold.

6. Frigidaire 50-Pint Dehumidifier with Effortless Humidity Control

best dehumidifier

This is the slightly smaller version of this particular Frigidaire model, which is available in three total sizes. Despite the size differentials among the three, all of the features and aspects remain the same, with the only real difference being in how much moisture the unit can remove per day.

With this being a 50-pint version, the unit is best-suited to rooms at or under 2,500 square feet.

Notable Aspects

“Effortless” is the goal for Frigidaire here, and that’s what you get. Humidity controls allow for exact settings that you can tailor to match your humidity preferences, or the size of the room. This allows for the unit to cycle on and off as needed without you having to do it yourself.

The spacious reservoir is easy to take out and dump, thanks to a splash guard and carrying handle. Dumping a tank is the most annoying task associated with a dehumidifier, so the easier the better. There is a continuous drain option, but there is no pump included, so you’ll need to rely on gravity to get the job done. A frost sensor protects your coils and keeps the unit safe during colder conditions.

If you are planning on keeping the unit running for most of the day, you’ll be glad to know it’s Energy Star rated, helping keep your utility bills down while also helping the environment,

Negatives: Just like its 70-pint big brother version, this isn’t a very quiet humidifier, so it’s best to avoid it if you’re in need of some peace and quiet. The volume makes the unit more conducive for parts of your home that you won’t be around very much. The lack of a pump makes your drainage options rather limited.


  • Energy Star certified for lower electric bills
  • Vibrant LCD screen with status indicators
  • Cleanable filter
  • Frost sensor
  • Very light and easy to carry for its size


  • Not very quiet
  • No pump for continuous draining


This unit’s quality is obvious from the outset. Everything about it is supposed to be easy, and Frigidaire definitely pulls it off, whether you’re emptying a full reservoir, changing settings, or getting the unit set-up to begin use. The 50-pint per day moisture removal rate is a versatile amount, allowing this unit to be used in a variety of spaced and sizes.

No, it’s not the quietest unit you’ll use, but it’s also not significantly louder than competitors. The numerous bonus features, simple controls, and ease of use makes this dehumidifier one of the better values.

7. EdgeStar 30 Pint Portable Dehumidifier - Best for RV’s

best dehumidifier

This unit from EdgeStar is geared towards those needing a quality dehumidifier, but in a much smaller space. A 30 pint moisture intake may not seem like a lot initially, but if you are using it for something like an RV, you have plenty of dehumidifying power to go around.

The size and weight of this unit makes it easy to store away when not needed, while also making it easy to move from room to room. The smaller stature doesn’t negate any normal dehumidifier features either. In fact, this EdgeStar unit can pretty much do what other units twice its size do, but for a cheaper cost, lower power amount, and less hassle overall.

Notable Aspects

First and foremost, this unit is quite small. EdgeStar recommends that you try to keep things around 400 square feet, but it may be used in rooms up to 1,500 square feet with acceptable success. Still, the smaller rooms is better suited for this unit, which is why it’s perfect for RV use: it uses lower power amounts, isn’t as loud, and takes up hardly any space at all.

This unit is Energy Star rated, so you don’t have to worry about jacking up your electric bill. It plugs into a simple 3-prong outlet, and weighs just 29 lbs total.

While the unit does include a hose connection option for continuous draining, the reservoir is easy to use, and holds up to one gallon. Again, this isn’t as much as larger units, but with the 30-pint moisture removal amount, you don’t need to worry about emptying the tank more than once a day.

All the typical settings and programs are included with this unit, such as auto shut-off, fan speed, and humidity level.

Negatives: The reservoir is indeed easy to use, but it is also prone to spill a bit due to its design. It's best to empty it before capacity just in case you don’t feel like spilling a bit of water here and there. Also, the filter situation is kind of bizarre -- you have the option to upgrade to a metal filter that is antimicrobial. Including it was a standard feature makes more sense, as many won’t care enough to upgrade a filter.


  • Energy Star Rated
  • Small
  • Lightweight
  • Lower Noise


  • Tank spills easily
  • Intentionally-inferior filter included as standard


This EdgeStar dehumidifier packs a lot of features and performance into a smaller package. The weight and size work to its advantage however, as it’s the perfect unit to bring along on an RV trip, or to use in a smaller area such as a bathroom. Modern capabilities and conveniences help propel this dehumidifier into the top tier for it’s size and power range.

8. 1byone 400ML Powerful Thermo-electric Dehumidifier - Best for Closets

best dehumidifier

Dehumidifying is a simple concept at heart, and sometimes that concept doesn’t require a large unit to get the job done. If you need a small space to be drier and free of humidity, you don’t need to worry about purchasing a bigger unit like the ones mentioned above. In such cases, a unit like this one made by 1byone is more than capable of the task.

This unit takes up barely any space at all, and uses a low amount of power. The operation is the same as bigger units as far as using a reservoir tank and a blower fan. If you are dealing with isolated humidity issues in areas like closets, bathrooms, or other small spaces, this unit is a good place to start.

Notable Aspects

The obvious advantage here is the size. Standing at less than a foot tall, the unit can fit pretty much anywhere, and doesn’t need much room for intake or air exhaust. It weighs under 3 lbs, so moving it around from room to room is quick and easy.

Now, the size also limits the space you can use it in, and 1byone recommends that you keep it under 100 square feet. You are welcome to try it in larger spaces, but don’t expect flawless performance. When used as recommended, you can remove as much as 170 mL of air moisture each day.

The unit doesn’t use a compressor, but relies on Peltier technology instead. This means a more quiet and simple operation than bigger units -- but not an entirely quiet operation. Still, it’s much quieter than a conventional unit.

The reservoir tank can hold up to 400 mL, which is impressive. In most cases, you won’t have to empty the tank more than once every few days. There is an auto shut-off built in that will power the unit down when the tank is full, so don’t worry about it slowly spilling over.

Negatives: Despite being very small, the unit still operates at a moderate volume, which is a bit disappointing. It’s not near as bad as larger units, but it’s definitely noticeable, so if you’re a light sleeper, you’re going to want to turn it off at night.


  • Very affordable
  • Simple operation
  • Auto shut-off
  • Low power use
  • Compact


  • Still a bit noisey
  • Only optimal for very small spaces


As long as you know its limits, this unit from 1byone can be very useful for specific applications. Musky closets, bathrooms, and even small bedrooms will be well-served with this dehumidifier, without jacking up your electric bill. The large tank and auto shut-off feature seals the deal in making this a great option for a cheap unit that is still capable of decreasing humidity.

9. Eva-dry E-333 Renewable Mini Dehumidifier - Best for Small Spaces in the Home

best dehumidifier

If you’re looking for a little more dehumidifying power than the 1byone, this unit from Eva-dry should do the trick. Standing only about an inch taller, the Eva-dry is perfect for pantries, closets, campers, and studio apartments that need some help from excessive humidity.

The major advantage with this unit is how it looks. With its minimal aesthetic and neutral color, the unit can be placed anywhere in your home without being a blight on your decor. Operation is as simple as it gets, and all the normal features such as auto shut-off and push-button on/off are included.

Notable Aspects

The Eva-dry can remove about 10 ounces of water per day from the air, all deposited into an easy-to-remove tank that’s located in the back of the unit. Simply pull it out, remove the lid, and pour out. The unit shuts off automatically after removal.

The style of the Eva-dry is very appealing, opting for a minimalist, modern design that still allows for you to easily track the reservoir tank’s level.

The Eva-dry is also incredibly quiet. It may even be quieter than your home’s air conditioner. Some may even appreciate the low-level white noise when trying to fall asleep at night. More importantly, you can leave it on as you sleep with peace of mind, as it will power off automatically if the tank is full, or if it overheats.

Negatives: the only real disadvantage here is the lack of dehumidifying power in terms of larger spaces. But that’s something you know you’re getting into when you buy it. Keep it confined to a small area and you’ll be just fine.


  • Stylish
  • Quiet
  • Auto shut-off
  • Easy tank draining
  • Efficient


  • A little pricier than similar models
  • One fan speed


If you want a small dehumidifier to leave out in your home without worrying about it affecting your decor, the Ever-dry is your best bet. Fortunately, it does more than look good, it actually works well. There is hardly any effort required to use it, and its capacity is suitable for smaller spaces without having to constantly check the tank.

Why use a dehumidifier?

Whether you have a basement that needs the humidity levels regulating or live in a sticky climate, a dehumidifier will help keep excessive moisture in check.

When a home is too damp, it is prone to produce fungus, mold and mildew. This can cause harmful effects present on the walls, furniture and even clothing.

Extreme amounts of humidity can also create a home for viruses and harmful bacteria that can gravely affect your health.

You should aim for a low humidity level of 30% and nothing higher than 50%.

Dehumidifiers are available in all sizes so you can choose the right one for your home.

Types of dehumidifier

There are two main categories of dehumidifier, Desiccant and Refrigerant.


  • The structure of this type includes:
  • Rotor
  • Process fan
  • ​Reactivation fan
  • Honeycomb matrix
  • How does it work?
  • The process begins with damp air being led to the machine by a process fan. This air is then whisked directly to a honeycomb matrix.
  • There, the rotors will absorb the moisture as the dry air is released. The rotor contains desiccant materials in the form of silica gel. When damp air passes through, moisture is sucked out through a network of microscopic intertwined pores.
  • The reactivation stage makes the absorption force weaker so the moisture is able to escape from the desiccant materials.


  • The structure of this type includes:
  • Fan
  • Water collecting tray or pipe
  • Cold evaporator coils
  • Warm condensing coils
  • How does it work?
  • The kind of technology works by condensing the humidity to help get rid of all the moisture in the space.
  • Damp air will be sucked by the fan and lead the air toward the cold evaporator coil for cooling. This makes the moisture turn into liquid water that is collected and removed either manually or through a drain.
  • The air will then proceed to the warm condensing. This heats it up before being released.

Desiccant vs Refrigerant


The refrigerant coil weighs more as it includes heavier parts. Due to the weight, manufacturers usually include wheels for easy mobility with refrigerant models.


Because of its smaller size, many assume that desiccant dehumidifiers are cheaper to run than those with refrigerant coils. In fact, the refrigerant runs on less energy.


Desiccant dehumidifiers are a fair bit quieter than refrigerants. Refrigerants use compressors to get rid of moisture from the air so kick out more noise.


The refrigerant coil is able to remove a large amount of water vapor each day. In areas with high amounts of moisture, this type works best.

Temperature Operation

The refrigerant coil dehumidifier uses cold air to evaporate moisture. The desiccant variety uses the porous form of granular silica to get rid of humidity without any unwanted heat.

How much does a dehumidifier cost to use?

Typically, the usual power consumption is about 150 to 800 watts. Dry air is cheaper to heat which means this tool can be a real help saving energy.

Dehumidifiers don’t just warm the hair but also capture the moisture and remove any dampness from cold air. You can save even more by purchasing a dehumidifier with a built-in laundry function mode. This will produce warm dry air when positioned properly.

What is a pint?

A dehumidifier uses the pint for sizing. Pint is a volume unit that is used in both UK and US measurement systems. It was 1/8 of a gallon though the US pint is 20% smaller than a pint in the UK.

  • UK: 1 pint = 568 ml
  • US: 1 liquid pint = 473 ml and 1 dry pint = 551 ml

What size do you need for your home?

Both weight and height are important considerations. Think as well about the amount of water removal needed each day. The more water you need to get rid of, the larger capacity dehumidifier you will need.

If the space is not always damp, choose a smaller capacity dehumidifier.

Where to put the dehumidifier?

Choose the area where the most humid and damp conditions occur. This can be the kitchen, bathroom, basement, or in a hallway.

Make sure not to run the dehumidifier in the room you are in (or sleeping in).

Can i leave the dehumidifier on all day?

Many manufacturers say this is fine although exercise caution. There is always some risk with any electrical appliance.

However, a commercial grade dehumidifier is an exception since it is built to run constantly without burning out.

Factors to consider

Add 10 pints if you live in a high humid climate. If there are many people living in your home or your house contains many windows and doors, add another 5 pints. If the area has a wash and dryer, add 5 pints. Refer to the Appliance Manufacturers guideline to determine the size that is most appropriate for your home.

Here is a useful way to determine how many pints your space needs, depending on size:

  • Under 30 Pints: This is acceptable for rooms of up to 1500 square feet. These models are perfect for smaller basements or 1000 square feet spaces with high humidity.
  • 40-50 Pints: This size is used for areas up to 2000 square feet as well as spaces that suffer from damp all the time.
  • 60-70 Pints: This is the advised capacity for spaces larger than 2000 square feet.

Follow these simple, important steps and you can choose the dehumidifier that is right for your home.


When it comes to humidity, feeling overly sweaty and uncomfortable is the least of your worries…

A moldy stench, crooked floors and peeling wall paint are all signs that you should definitely buy a dehumidifier before it’s too late.

As with anything in life, prevention is better than cure. Investing in a dehumidifier is very worthwhile. You cannot put a price on your health.

The NewAir AD-250 25 Pint Portable Dehumidifier is designed for use in small rooms. Don’t let its size fool you though. It has the ability to drain water continuously, and even an auto-defrost function which is a feature commonly reserved for more expensive dehumidifiers. It’s also really quiet and energy efficient.
