Hardly can you talk about dehumidifiers without mentioning Black & Decker, with the company being one of the oldest and biggest companies in the industry.

Available in different variations, the BLACK+DECKER BDT30WTA 30 Pint Energy Star Portable Dehumidifier perfectly blends the construction of a tank-like unit with the machine’s simple working principle. When it comes to coverage area, this machine is the best model on this list, with its ability to cover up to 5,500 square feet.

In terms of aesthetics, this machine is quite different from other models, as it is sleek and elegant in its design. The fact that it comes with four mobile caster wheels and an easy-to-use handle for optimum movability.

Apart from being capable of removing 30 pints of moisture daily, this unit also has three dedicated fan modes, which enable you to pick between efficiency and power.

It’s also equipped with a small LED display, which provides accurate humidity levels. The LED display also helps users to effectively select the mode of the fan without any hassle.

And since it comes with an eco-friendly R410-A refrigerant, which makes auto de-frost very easy. For energy-efficiency, it also comes with an auto cut-off technology, which is also another safety-aiding feature.

To ensure that the machine stays in peak conditions at all times, there is also a clean filter indicator, which alerts you when it’s time to clean the filter. It also has a quiet operation, which makes it ideal for bedroom usage.

Water tank capacity: 7 pts

Fan speeds: 2

Dimensions: 19 x 13.3 x 9.6 inches

Warranty: 1-year parts/labor

More features: Single bucket with light indicator and audible beeping alarm

Haier has for a long time been one of the leading companies when it comes to the manufacturing of dehumidifiers and this model shows exactly why. Its remarkable coverage area and small size make it perfect for basements.

Another thing that makes it ideal for homes and basements is how it’s equipped with two indicators to alert you when the reservoir is full. This makes a lot of sense since you’re likely to be using your dehumidifier in your basement a lot, as basements often have high humidity levels.

The indicators and alarm that goes off when the tank is full means you will know when to empty the tank. However, you’re not likely to be doing this too often since the dehumidifier comes with a one-gallon water reservoir.

In addition to that, the filters that come with this machine are easy to remove and clean, which is also a huge plus, especially if you will be using this 30-pint dehumidifier inside your basement.

Since they are easy to remove and clean, maintaining this unit and making sure it stays in peak condition will be easy for you. It’s also worth noting that this Haier dehumidifier features an easy-to-read display, which shows why it’s so rated highly.

However, while this dehumidifier comes with a lot of excellent features and big positive highlights, its noisy operation might be a deal-breaker for some people. Unfortunately, it has a fairly loud operation, and that means that you like having it around at all times.

Why is it special?

  • Portable construction
  • Easy-to-access filter
  • Full tank indicator light and alarm
  • Easy-to-read display
  • Large coverage area

What are the flaws?

Furthermore, the device comes with a touch control panel, which allows you to set exact humidity settings ranging from 35 percent to 85 percent. You can even set the timer and regulate the fan speed, even though the machine will bump the fan up automatically in extremely high humidity conditions.

Bear in mind that this machine enters a three-minute rest period automatically upon completing a moisture removal cycle. This is an excellent feature that aids safety and operation automatically resumes as soon as the three-minute rest period is completed.

In terms of cons, we wish that a manual came with this unit. Not only does it lack an included manual, but there’s also no manual for it online. Besides, it can be very noisy if you don’t set it to the perfect level.

Why is it special?

  • Large functional temperature range
  • Continuous drainage feature
  • Has a rest period
  • High energy-efficiency
  • Adjustable fan speeds

Featuring digital controls and a humidistat, the Soleus Air DS1-30-01 Dehumidifier is one of the most advanced dehumidifiers in the market. It allows you to completely program the machine to your liking.

It comes with three fan speeds, but we’ve got to admit that it has a pretty loud operation, based on the speed you’ve set. The machine also comes with an auto defrost mode, which enables it to work at lower temperatures up to 41 degrees Fahrenheit.

Moving on, there is a smart auto-restart feature, which turns on the machine again if there’s power outage. It maintains all your previous settings, so there’s no need of setting it up again.

With its capability to cover up to 1500 square feet, there’s no denying of the power of the Vremi 1,500 Sq. Ft. Dehumidifier.

If you don’t like emptying the reservoir continuously, you can attach a hose for nonstop gravity draining. It’s also worth mentioning that the machine also features a filter to eliminate allergens like dust, mold spores, and bacteria.

Like the tank, the filter is also easy to remove and clean. The machine is automatically set to ‘continuous mode” during the first use, which inactivates the controls that allow you to set the preferred humidity levels.

When you’re using normal model, it doesn’t make as much noise, so you may use the machine for average household use. Also, this machine is equipped with some automation features like the 24-hour timer.

Things to Consider

This the business end, being where you will find all the tips and information you need for your shopping. With that said, we’ve done everything to make sure this section is as helpful as usual.

Advantages of 30-pint models

If you’re wondering what you stand to gain if you buy this product, maybe it’s time you read the advantages of 30-pint dehumidifiers below:

Reduces levels of humidity to reduce mold, odors, and mildew in the air – two of the most moisture-related issues that a home can have is mildew and mold.

This is capable of causing severe damage and also endanger your health, plus it’s capable of causing a pretty unpleasant odor. A 30-pint dehumidifier is capable of making a big difference in making sure this won’t happen.

A 30-pint dehumidifier protects your stored items, in order to prevent them from getting damaged – too much moisture or humidity can cause damages. Tiles and walls can become loosen and warped as moisture is a serious problem.

Spread the air to prevent musty odors usually triggered by stagnant air – a 30-pint dehumidifier is capable of injecting some fresh smell into your home.

Stagnant air can cause odors and dust to remain in your space, which may cause greater problems with allergies or make your home smell terrible. Dehumidifiers can easily help you solve your allergy problems.

Features to consider while choosing a 30-pint dehumidifier

Perfect for homes and offices, 30-pint dehumidifiers are becoming more and more popular on a regular basis. With that said, it’s important to know some important features to consider before buying one of these machines.

Coverage area

Probably the first and most important feature you need to consider is the coverage area. If you want to buy the ideal model with the ideal coverage area for the area you want to dehumidify,

you just need to figure out your space’s size, and look for a model that can process the volume of the air in that area effectively. This will prevent you from choosing a unit that will likely underperform.

Most companies usually state the coverage area of their products, so you shouldn’t have any problem finding this information. Meanwhile, the BLACK+DECKER BDT30WTA 30 Pint Energy Star Portable Dehumidifier has the largest coverage area on our list, with its ability to cover 5,500 square feet.

Continuous drain option

Primarily, continuous drainage determines whether you have to manually empty the moisture tank or not, or whether you can connect the reservoir to another outlet so that it can drain itself. With this, you won’t have to be regularly carrying out maintenance.

Another thing is that continuous drain will depend on being connected to drainage system or an outlet so that the collected water can be gotten rid of. It will be a huge plus if you can find an affordable model with this feature, particularly if you utilize your machine a lot.

Water tank capacity

If you choose the continuous draining option, the water tank capacity may not really matter as it will be emptying itself. However, if you’ll be doing this manually, you’ll probably need a pretty large water tank capacity, such as the Vremi 1,500 Sq. Ft. Dehumidifier.

The amount of water you eventually up with depends on the level of humidity and the unit’s effectiveness. However, if your tank is not really big, then you may end up needing to empty it on a regular basis. The compromise is that a larger moisture tank means the machine will take up more space.

Noise level

Dehumidifiers are sometimes noisy, which is typical of this kind of appliance. The motor and fan components in it will not be silent, and some models are actually capable of producing high sound levels.

Meanwhile, there are some models that do not produce much noise, such as the Frigidaire 30-Pint Dehumidifier and the Eurgeen 30 Pint Smart Touch Screen Small Dehumidifier.

If you find it difficult to find sleep with a noisy machine around, then it would be better to opt for a quiet machine.

Dimensions and weight

It’s also very important to consider the dimensions and weight of the dehumidifier you want to buy. First of all, you need to consider the dimensions so as to make sure that it will fit in the space you have available. You also need to consider the weight, especially if you are likely to be moving the machine around a lot.


Whenever you are buying an electronic product, the ideal thing is to make sure the product you’re buying comes with a warranty. The warranties that come with dehumidifiers can vary considerably. For example, the Keystone 30 Pt Dehumidifier comes with a five-year warranty, while others may have none.

One-year warranty, covering most models like BLACK+DECKER, Haier, Tosot, Vremi, and Perfect Aire dehumidifiers, is the industry standard though, so you shouldn’t consider any model that falls short of that in terms of warranty.

Extra features

Many companies add as many as possible features, which can increase the ease of use and overall experience. For example, some models have LCD or LED indicators to show the level of humidity.

Some of the best dehumidifiers have defrost options, which means they defrost themselves automatically at low temperatures.

Other big features include auto shut-off, which comes in handy when the moisture tank is full. Auto start-up can also be useful, which restarts the dehumidifier after a power outage.

How to maintain a 30-pint dehumidifier?

Strategic placement of your dehumidifier – It is vital to position your unit in a place where air will efficiently circulate through it. Keep it six inches at least away from the wall so that its air intake and exhaust aren’t blocked.

Adjust your room’s humidity level – Apart from the room temperature, the room’s humidity level also determines the lifespan and efficiency of a dehumidifier. The indoor humidity level can be controlled by regulating the humidistat.

Replace or wash the filter – Every dehumidifier comes with a guide that recommends a time-frame within which its filter needs to be changed. Some air filters are cleanable and can be regularly washed. Adhere to these recommendations regularly so your dehumidifier can remain in top conditions for a long period.

Clean the dehumidifier’s coils – Dehumidifier coils have a tendency of causing freezes whenever a lot of dust is collected. Therefore, you need to regularly vacuum and clean them.

Check the dehumidifier’s coils for frost – Your dehumidifier can have frost if it’s been working in a cool temperature, and frost can reduce its efficiency. If you feel there’s frost in the internal coils, try to check the coils as soon as you’ve turned off and unplugged the appliance.

Clean the water container regularly – To prevent a potential health hazard, make sure you keep a tab on the water tank to make sure it’s germ-free always.

Avoid switching the unit on immediately after switching it off – Just like every other electronic unit, wait for ten minutes at least to turn your machine back on after it’s been turned off. If you turn it on immediately after turning it off, it can spoil its compressor.


Can I leave a dehumidifier running overnight?

If it’s really necessary and you don’t see any chance of overflowing or leaking, you can leave it running overnight. Most of the products on our list come with an auto shut-off feature, which kicks in when the tank is filled up.

Are there filters that should be changed regularly?

While there are some filters that can’t be washed or cleaned, most of them are. Therefore, you may necessarily not need to change your filter on a regular basis. You’ll just need to be cleaning it regularly, but make sure it’s a washable filter.

Where at home mold is most likely to develop?

Mold usually grows in damp and wet places. Of course, the places that is likely to be wet in your home are the bathroom and the kitchen, so watch out for mold in those places.

Our Verdict

While it may seem like a strange choice, the Frigidaire 30-Pint Dehumidifier is our Editor’s pick, thanks to its combination of all the important things.

It’s coverage area is not close to the largest on this list, we know, but it was actually designed for medium-sized rooms. It doesn’t only have one of the largest tanks on our list, but it also comes with many advanced features. It’s the best 30 Pint Dehumidifier on our list, but only by a slight margin.

Trailing it closely is the model with the largest coverage area on our list by far, the BLACK+DECKER BDT30WTA 30 Pint Energy Star Portable Dehumidifier.

Apart from having the largest coverage area, it also has the second one of the largest water tanks. On top of that, it has multiple fan speeds and many advanced features, making it as customizable as possible.

Our third pick is the Haier HEN30ET Dehumdifier. While its manufacturer is not as reputable as Black & Decker, we think they have made a huge statement with this product.

It almost doesn’t have any flaw whatsoever, with its rather noisy operation being the only noticeable shortcoming we could see. It’s such an excellent machine with a touch of class.
