Product Reviews

We love 30-pint dehumidifiers due to their size and effectiveness. While we looked for the best 30-pint dehumidifiers on the market, area coverage was an important factor. In addition, we chose units that offered different drainage options for more convenience.

1. Vremi 30-Pint Energy Star-Rated Dehumidifier

Best Overall

The Vremi Moisture Maniac 30-Pint Dehumidifier is one of the most popular of its kind — and it’s easy to see why. It works quickly and energy-efficiently, and you can get it started immediately, thanks to the easy setup.

The size of this unit is excellent for medium to large areas of up to 1,500 square feet. The compact size means you can place it anywhere in the living room or bedroom. There are even two handles on each side to help you carry the unit.

When you first get it started, the unit will automatically be set to continuous mode. Simply turn this off and adjust it to your desired levels. You can do this using the arrows on the display.

What We Like

User-Friendly Design

The Vremi 30-Pint is a popular model due to its user-friendliness. You can set your desired humidity levels on the humidistat, and the unit will run continuously until it’s achieved. There’s no need to worry about the tank filling up because the auto-shutoff function will prevent it from overflowing.

Continuous Drainage

It’s not always possible to empty the tank, so you can opt for continuous drainage for your convenience. All you have to do is attach a hose to the unit and draw it to a nearby drain or sink. The dehumidifier will then work non-stop until the desired humidity is reached or you turn it off.

Sleek Modern Design

One of the main things we really appreciate about the Vremi is its design. It has a sleek, modern look and isn’t as cumbersome as other 30-pint dehumidifiers. You can easily place it in the corner of the living room without it looking out of place.

Filter to Remove Odors

Humid air can feel clammy and smell musty. Luckily, the Moisture Maniac has a very convenient solution. It’s fitted with a fine filter that removes bacteria, mold spores, dirt, and other impurities from your air, leaving it clean, fresh, and dry.

The filter is also easy to maintain. It can be reused by washing it once a month or whenever necessary.

What We Don't Like

Loud Volume, Even on Low

The Vremi 30-pint might be compact, but it’s also loud. It has different settings; however, it can still be quite loud even when on low.

It Needs Emptied Daily

While this has a spacious tank of one gallon, it still requires frequent emptying. Customers were surprised that they needed to empty this most days, if not more often.

Product Specs

Room Coverage 1,500 square feet
Bucket Capacity 1 gallon
Dimensions 16.1 by 10.4 by 19.9 inches
Weight 30.9 pounds
Warranty 12-month warranty

2. Tosot 30-Pint Portable Dehumidifier

Most Quiet

The Tosot 30-pint dehumidifier is another excellent unit. It has various convenient features, such as continuous drainage and automatic power outage restart. It’s Energy Star-rated, which means you can save a few bucks on your electricity bills.

However, the design is a bit cumbersome. Although it has four wheels, it can be tricky to move around depending on your floors. Despite this, customers love its effectiveness and quiet operation — even when on high.

What We Like

Quiet at 48 Decibels

Unlike other 30-pint dehumidifiers, the Tosot works quietly. You can easily use it in your bedroom during the night or in the living room when guests are over. Tosot has measured it at 48 decibels on the lowest setting and 52 on the highest.

Easy to Maintain

When the bucket fills up, you can quickly locate it at the front of the unit — simply slide it out and carry it to a sink to empty it.

After taking the bucket out, you can pull the air filter down and check if it needs to be cleaned. If so, wash it in warm water and a mild detergent. Then allow it to dry fully before placing it back into the unit.

Continuous Drainage

Use continuous drainage if you need to work the dehumidifier continuously and don’t have time to empty the bucket. You simply attach a standard garden hose to the outlet and draw it to a nearby drain or sink. This feature is very convenient, especially if the dehumidifier is in a place where it’s easy to forget, such as the basement.

You Set the Target Humidity

To save energy, you can set this to reach a certain target. Once it reaches that target, it will turn off, saving you energy. If you’d rather it run continuously, you can set it to the “NS” level, and it will switch off once the tank is full.

What We Don't Like

Small Wheels Don’t Work on Carpet

The Tosot 30-pint dehumidifier is fitted with four wheels to help you move it around. However, the wheels are small and will only roll on hard floors. This means if you have carpets, it can be tricky.

Doesn’t Last a Long Time

This comes with a one-year warranty; after that, customers noted that the unit began to break down. If you want something that will last years ahead, this is not the most durable.

Product Specs

Room Coverage 1,500 square feet
Bucket Capacity 1 gallon
Dimensions 13.4 by 9.9 by 19.5 inches
Weight 34 pounds
Warranty One-year warranty

3. Ivation 30-Pint Dehumidifier

Best 30-Pint Dehumidifier for Large Spaces

If you need a dehumidifier to cover a large area, the Ivation is an excellent option. It works very fast and can cover up to 2,000 square feet. We love how easy it is to operate and all the handy features and options it comes with.

It’s also an excellent choice for anyone living in colder areas since it has frost sensors that keep the coils working. In addition, you can quickly remove the air filter and give it a wash when needed. This will further keep the dehumidifier working effectively.

What We Like

Excellent for Larger Areas

Unlike most 30-pint units that only cover 1,500 square feet, this dehumidifier can cover an impressive 2,000 square feet. The design is surprisingly compact, and weighing only 31 pounds, it’s also easy to move around.

Easy to Use and Manuever

The Ivation 30-Pint Dehumidifier has a handful of handy features, such as four caster wheels for easy portability. It also has two fan settings, a built-in relative humidity meter, a timer, and auto-shutoff. You can set all your desired settings on the LCD display.

6-Feet Long Cord

The importance of the length of the power cord is often forgotten, which we often regret. A short cord is useless, especially because an outlet isn’t always nearby. Luckily, this dehumidifier comes with a six feet long cord that gives you more freedom to choose the right spot.

Auto-Defrost Helps During Winter

If you live in an area that sees cold winters each year, you might be apprehensive about choosing a refrigerant dehumidifier. However, this unit has an auto-defrost function that detects freezing temperatures on the coils. As a result, it prevents the evaporator coils from freezing over and wasting energy.

What We Don't Like

Hose Drain Is Difficult

Although the dehumidifier works great, it can be tricky to attach the hose. Several customers struggled with this, and a few experienced drips. There have also been a few reports about missing screws that must be purchased separately.

Everything About the Unit is Small

Now, this may not be a bad thing in terms of finding somewhere to set this up. But the tank fills up very quickly, and it’s only 0.8 gallons. Plus, the controls on the unit are small and hard to read, especially in dim lighting.

Auto Shutoff Fails

From time to time, the auto shutoff function will fail. The unit won’t shut off, and the tank will start to leak, leaving water underneath the unit and on your floors.

Product Specs

Room Coverage 2,000 square feet
Bucket Capacity 0.8 gallons
Dimensions 14.2 by 9.9 by 20.1 inches
Weight 31 pounds
Warranty One-year warranty

4. Inofia 30-Pint Basement Dehumidifier

Best 30-Pint Dehumidifier for Basements

If you need a compact and quiet dehumidifier, this is for you. The Inofia is as simple to operate as possible — there are only four buttons to get familiar with. Despite this, it has several smart features to help make maintenance a breeze.

You can drain into the 0.5-gallon bucket or attach the included hose for continuous drainage. In addition, the sleep mode option makes this dehumidifier the perfect choice for bedrooms and kids’ rooms.

What We Like

Easy to Get Started

To get started, simply plug the dehumidifier into a nearby outlet and then select your desired settings. The display is easy to figure out with only four buttons and a few indicators. You can set your desired humidity levels quickly and adjust the timer and fan speed.

Before You Begin

Inofia recommends allowing the unit to stand at least 24 hours before you plug it in.

Breezy Maintenance

Maintaining a dehumidifier is often overlooked and some units seem to make it such a chore. However, the Inofia dehumidifier makes it a breeze with its smart maintenance features.

First of all, the filter is easily removed and washed. Next, the low-temperature operation protects your unit by defrosting it when working in temperatures down to 41 degrees. Plus, the bucket is easy to locate at the back of the unit and easy to carry to a nearby sink.

Quiet Sleep Mode

Although this dehumidifier is intended for basements, it still has a quiet sleep mode. If you need it in your bedroom or child’s room, simply plug it in and set it to sleep mode. The unit will work at a low fan speed that resembles white noise — you get a peaceful and dry night’s sleep.

Two Drain Options

For your convenience, you get two drain options to suit your lifestyle. First, the bucket can hold up to 0.5 gallons of water before automatically turning off until emptied.

In addition, you can opt for continuous drainage and attach the included 5.65-foot hose. The dehumidifier will then work non-stop to achieve a comfortable humidity level for you.

What We Don't Like

Small Water Reservoir

If you choose not to use the hose for continuous drainage, you could be emptying the tank more than once daily. At half a gallon, it’s half the size of other devices’ capacities.

Not for Large Spaces

If you have a grand basement with tons of space, then this might be underwhelming for you. Due to the smaller bucket capacity, this is best suited for smaller spaces as you’ll need to empty it more often.

It Sometimes Leaks

The auto shutoff function is hit or miss. If you’re planning to set and forget this dehumidifier, you might return to some leaks.

Product Specs

Room Coverage 1,056 square feet
Bucket Capacity 0.5 gallons
Dimensions 12.2 by 8.2 by 17.3 inches
Weight 24.9 pounds
Warranty One-year warranty

5. Black+Decker BDT30WTB 30-Pint Dehumidifier

Easiest to Move

The Black + Decker 30-pint dehumidifier is a good choice for a small, portable option. It can extract up to 30 pints of water from the air in just 24 hours, making it ideal for basements, cellars, or bigger rooms in the house.

It’s not bulky or too ugly, either. So whether you have a modern or cozy aesthetic in your home, this dehumidifier has been designed to fit right in without being obtrusive.

What We Like

Easy to Use and Empty

If you’re new to the world of dehumidifiers, this is a great starting point. It’s super easy to use. First, it has a user-friendly LED display panel so you can easily customize your settings.

Next, choosing your preferred fan speed options is simple, as there are three options: low, medium, and high. There is also an adjustable humidistat.

Finally, when the tank is full, there’s an easy access point to remove the 8.0-pint tank. Just remove it, empty it, clean it and return!

Goodbye Mold and Mildew

Customers praise this dehumidifier for removing mold, mildew, and moisture. Having high mold levels and mildew in the home can be dangerous. This dehumidifier gives you extra reassurance and safety in the home by removing it.

Because it’s lightweight and compact, you can also bring it on your travels. Take it to your vacation home, or bring it with you in your RV.

Extra Drainage

You can connect the unit to a garden hose for additional drainage if you don’t want to empty out the water tank as often. This is great for leaving it running while you’re enjoying a day trip or for removing mold and mildew, so you don’t have to deal with the gross build-up in the tank. Of course, we still recommend cleaning this regularly to remove the build-up as needed.

Environmentally Friendly Design

This dehumidifier is Energy Star certified, making it kinder to the environment. Not only will you save energy, but the filter is washable. This means you save money, but also produce less waste overall.

What We Don't Like

Quality Issues

Beware — some customers reported inconsistencies in this unit’s motor performance. They’ve added that there are instances wherein the motor completely stops for no apparent reason.

Starts Making Loud Noises

While it was pretty quiet upon arrival, many customers started noticing loud rattling noises after a few weeks. These noises were impossible to sleep through, and you could even hear them from another room!

Not Suitable for Winter

In cold months, this unit is known to freeze up. It doesn’t automatically defrost, which makes it inconvenient if you live somewhere chilly.

Is a 30-Pint Dehumidifier Big Enough?

To determine whether a 30-pint dehumidifier is right for you, consider how humid or damp your home is. We recommend one for moderate to very damp environments. Look for the following signs:

  • A musty odor that is either always present or only occasionally.
  • Clammy feeling.
  • Damp spots on walls or floors (1).

Most 30-pint dehumidifiers can cover between 1,000 and 1,500 square feet, with some going up to 2,000. However, if you have a 1,500 square-foot space that’s so humid you see water beading on the walls, 30 pints may not be enough.

What to Look For (Buying Guide)

Once you’ve decided that a 30-pint dehumidifier is for you, it’s time to find the best device for your home. Here are a few things worth considering to find the right unit for you.

Area Coverage

As mentioned above, 30-pint dehumidifiers generally cover between 1,000 and 2,000 square feet.

However, it’s still important to check this when considering a dehumidifier. Some 30-pint units will only cover a little over 1,000 square feet. Therefore, you should measure your space before deciding.

Bucket Capacity

Although a 30-pint dehumidifier can remove 30 pints of water daily, that doesn’t mean it can hold 30 pints. It’s essential to check how much water the bucket can hold and consider what will suit you.

We highly recommend choosing a unit with a bucket capacity of at least one gallon. Alternatively, choose one that offers continuous drainage, so you don’t have to empty it at all.

A Note About Convenience

A small tank will need to be emptied often, depending on the humidity. This can be inconvenient as you have to spend time taking it out and putting it back several times a day.

Size

30-pint dehumidifiers come in a range of sizes. Some are small and compact, while others are large and cumbersome. Before deciding on a unit, consider where it will be placed within a room. It may not fit properly or look out of place if it’s too large.


FAQs

Can One Dehumidifier Do a Whole House?

One dehumidifier can do an entire house, provided it has the power and capacity. Whole house dehumidifiers are larger, with increased power to deal with higher moisture levels.

Is It Bad to Oversize a Dehumidifier?

It can be bad to oversize a dehumidifier because it will extract too much moisture from the air, leaving your interiors with dry air. This causes red eyes, sore throats, dry skin, and breathing difficulties.

Do I Need a 30-pint or 50-pint Dehumidifier?

Whether you need a 30-pint or 50-pint dehumidifier depends on the size of your space and the moisture levels. Budget is also a factor because a 50-pint model will cost much more than a 30-pint dehumidifier.

Are There Dehumidifiers That Don’t Need to be Emptied?

You can buy dehumidifiers that don’t need to be emptied. They have a hose that feeds directly into a drain or run-off to feed the water away safely. It removes the need for two or three trips to empty the water collection bucket.

This Airplus is an excellent example of a 30-pint dehumidifier with a hose attachment.

Do Dehumidifiers Use a Lot of Electricity?

Dehumidifiers do not use a lot of electricity. They consume the equivalent of running your dishwasher for 30 minutes or a standard laptop.


Choosing 30 Pints

30-pint dehumidifiers are excellent for medium-sized spaces. Most can cover around 1,500 square feet, and others can cover up to 2,000. Although some 30-pint dehumidifiers can be large, you can still find lightweight models.

When searching for the best 30-pint dehumidifier, we recommend that you consider its room coverage carefully. In addition, you must choose a bucket capacity that suits your needs.
