Is a 30-Pint Dehumidifier Big Enough?

Whether or not a 30-pint dehumidifier is big enough is a personal preference. A good way to figure out whether or not it’s suitable is to consider how humid or damp your home is. A 30-pint unit is generally recommended for moderate to very damp environments. Look for the following signs:

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

Most 30-pint dehumidifiers are able to 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.

How to Choose the Best 30-Pint Dehumidifier

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 we mentioned above, 30-pint dehumidifiers will 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 per day, 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 1 gallon. Alternatively, choose one that offers continuous drainage so you don’t have to empty it at all.

Take Note

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.


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. If it’s too large, it may not fit properly or look out of place.

Keep In Mind

A large tank will result in a larger dehumidifier.

The Best 30-Pint Dehumidifier of 2022

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 30-Pint Dehumidifier

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 right away, 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’s 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 to your desired levels. You can do this using the arrows on the display.

The Pros

Easy to Use

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 for your convenience, you can opt for continuous drainage. 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.

Easy to Look At

One of the main things we really appreciate about the Vremi is its design. It has a sleek and 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.

Removes 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.

The Cons


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

Additional 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

Best Quiet 30-Pint Dehumidifier

The Tosot 30-pint dehumidifier is another excellent unit. It comes with a range of 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 it due to its effectiveness and quiet operation — even when on high.

The Pros


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

If you need to work the dehumidifier continuously and don’t have time to empty the bucket, use the continuous drainage. 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.

The Cons

Small Wheels

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

Additional 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 of 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.

The Pros

Excellent for Larger Areas

Unlike most 30-pint units that only cover up to 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.

Handy Features

The Ivation 30-Pint Dehumidifier comes with a handful of handy features, such as four caster wheels for easy portability. It also comes with 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.

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 6-foot long cord that gives you more freedom to choose the right spot.


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.

The Cons

Hose Drain Is Difficult

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

Additional Specs

Room Coverage 2,000 square feet
Bucket Capacity 1.3 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 it can get — there are only four buttons to get familiar with. Despite this, it has several smart features to help make maintenance a breeze.

You can choose to either 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.

The Pros

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 quickly set your desired humidity levels, adjust the timer and fan speed.

Before You Begin

Inofia recommends that you allow 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 all of 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 then work at a low fan speed that resembles white noise — you get a peaceful and dry night’s sleep.

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 at achieving a comfortable humidity level for you.

The Cons

Small Water Reservoir

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

Additional 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

Best 30-Pint Dehumidifier for Mobility

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 which makes 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.

The Pros

Easy to Use

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, it’s simple to choose your preferred fan speed options as there are three options: low, medium, and high. There is also an adjustable humidistat.

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.

The Cons

Quality Issues

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