A dehumidifier is a household appliance that works to reduce the amount of humidity in the air. It helps you avoid a host of problems that come with excess moisture. Some of these include the growth of mold, dust mites, mildew, and harmful bacteria and viruses.

Dehumidifiers make the environment hostile to the growth of the allergens. It saves you money in the long run, in more ways than one. You won’t have to pay for pricy mold removal, and your AC unit will function better, taking a load off your electric bill.

What is a 30 Pint Dehumidifier Best For?

Today’s dehumidifiers can dry off 750ml per day all the way to 70 pints (About 9 gallons). Between these two extremes is the sweet spot, the 30 pint (about 4 gallons) device. They’re ideal for small to medium sized rooms. Most fall in the 40 to 60 decibel range, which is a good for home use. Quieter ones are great for bedrooms and common rooms, especially for 500 to 1,500 square feet.

House basements exhibit higher levels of humidity in comparison to the rest of the home, and will definitely require more powerful dehumidifying options. Dehumidifiers with larger area of effect (between 1,500 and 2,500 square feet are ideal for basement use. They’re louder than normal dehumidifiers thanks to their powerful fans, and this also makes them perfect for the secluded space in the basement. Dehumidifiers are also used in boats, but only when they are moored.

How to Choose a 30 Pint Dehumidifier

Choosing the right dehumidifier can be tricky, especially if you’re new to this category of consumer electronics. Here are some factors you should consider.

Moisture levels

Get a hygrometer to test the humidity levels in your home. Anything above 50% and you should definitely get a dehumidifier. Buy one that matches the relative humidity in your home. There are guides online to help you assess this.

Square footage

Identify the amount of space you’re dealing with. You can physically measure your space, or consult the floor plans of your house. Knowing the size will help you identify the right size dehumidifier for you.


This is measured in pints or gallons. The larger your space, the higher the capacity you will require from your dehumidifier. Otherwise, you’ll have to keep emptying the tank. You should also factor in the wetness levels in the room. A laundry room or kitchen will require more capacity in comparison to your bedroom.

Now that you know the space you are working with and the capacity you need, the next step is to compare the options available. This can be done from buyer’s guides and reviews. Pick the dehumidifier that best fits your needs for the budget you are working with. Be on the lookout for additional features such as auto-restart and digital controls.

Review of the Best 30 Pint Dehumidifiers

Let’s take a look at the best options available in the market. We’ve chosen the best in several categories, to help you pick what suits you best.

hOmeLabs 1,500 Sq. Ft Energy Star Dehumidifier for Medium to Large Rooms and Basements


  • Caster wheel for portability.
  • Quiet fan even on high settings.
  • ENERGY STAR rated for efficiency.
  • Easy to operate though the controls.
  • Modern eye-catching design with impressive workmanship.


  • Tank size is an issue for such a powerful dehumidifier.

Our Review

At 15.2×10.2×19.7 inches, this is the smallest machine in the hOmelabs line up. The design is a combination of clean lines and sleek panels, and comes with 4 multi directional caster wheels to make the device portable. The fan has two settings – normal and turbo. The normal setting takes in 129 cubic feet of air per minute, while the turbo takes this number up to 138 cubic feet.

The controls are easy to use. The touch control panel that lets you set it up for auto shut-off, restart, defrost the coils, and even change the fan settings. It also has a 24 hour timer. First-time users should note the dehumidifier reverts to a default “continuous” mode, which renders the left/right buttons on the controls useless. To regain the use of these buttons, you simply have to turn off continuous mode while the device is still on.

To use this device, all you have to do is input the ideal humidity setting and let it run for 24 hours, or until the 3 liter water tank is full, after which it will switch itself off automatically. The tank is easy to remove, empty, and clean. It comes with the option to continuously drain it through a pipe. The pipe, however, is not included at purchase, although a standard 5/8 inch garden hose does the job perfectly.

The hOmeLabs 1,500 Sq. Ft. Dehumidifier comes with a 2 year warranty, extended by a further 6 months if you register on the manufacturer’s website. It comes with an ENERGY STAR rating for energy efficiency, and also takes care of odor-causing bacteria through its high compression pump.

Bottom Line

This is a powerful all-rounder that takes all the technical aspects of running a dehumidifier out of the equation. It’s perfect for large rooms, storage spaces, offices, and conference areas. It is important to note – however – that this unit is not designed to work in the same room as an evap cooler.

Vremi 22 Pint 1,500 Sq. Ft. Dehumidifier Energy Star Rated for Medium Spaces and Basements


  • Easy to remove and clean filter.
  • ENERGY STAR certified for efficiency.
  • Powerful fan with continuous operation.
  • Various modes available under settings.
  • Caster wheels and handles for portability.


  • Fan is noisy at highest setting.
  • Tank is small and needs constant emptying during high humidity seasons (3 to 4 times a day).

Our Review

The Vremi 30 Pint Dehumidifier is a powerful Dehumidifier that covers 1,000 square feet. Excess moisture drips into tank that holds 3 litres. The tank itself is an easy-to-remove, clean, and re-insert, with instructions printed in the product. If you’re not a fan of continuously emptying the tank, you can add a hose for continuous gravity draining. This should be led to a low drain for best results.

The unit also comes with a filter to remove allergens such as mold spores, dust, and odor-causing bacteria. This filter is easy to remove, and you can wash it under running water. Do this at least once a month to keep your dehumidifier healthy.

During first use, the product is set to ‘continuous mode’. This disables the controls that let you set the desired humidity levels. Disable ‘continuous mode’ and the rest of the controls should work. It comes with 6 settings for different humidity levels, including a 24 hour timer. This device is ENERGY STAR rated for efficiency, meaning it won’t make a noticeable change in your power bill.

Although this product is rated for large rooms, it works best for medium sized areas. Its most powerful turbo mode switches it to move 138 cubic feet per minute. However, at this setting, there’s a noticeable noise from the machine. This makes it unsuitable for the bedroom if you’re a light sleeper. It also increases the unit’s power consumption. It does come with an auto shut-off, which kicks in then the tank is full.

Bottom Line

The Vremi 30 Pint Dehumidifier is powerful enough for mid-sized spaces, but its noise levels can be tough to sleep through. You might need noise-cancelling ear buds or a white-noise machine to mask it.

TOSOT 20 Pint 1,500 Sq Ft Dehumidifier Energy Star - for Home, Basement, Bedroom or Bathroom - Super Quiet (Previous 30 Pint)


  • Ultra-quiet.
  • Easy to use digital control panel.
  • ENERGY STAR rated for efficiency.
  • Wide humidity and temperature range.
  • Beautiful compact and portable design.
  • Auto shut-off and auto restart capabilities.


  • Small one gallon tank.
  • Customer service is hard to reach.

Our Review

This is an ultra-quiet compact dehumidifier that works well in medium and large spaces of up to 1,500 square feet. This makes it ideal for basements, storage spaces, and even large homes. It’s capable of removing up to 4 gallons of water from the air every day, and all this is done at less than 50 decibels. This means that the product not only blends in with the environment, it is also as quiet as a whisper.

The TOSOT 30 Pint 1,500 Sq. Ft. Dehumidifier is full of useful smart features such as the auto restart, which turns it on automatically – with its previously input settings – when power comes back after an outage. This is excellent for the basement, because you don’t have to physically go down there and turn it on. You can also schedule your dehumidification with 2 and 4 hour delay times.

Other smart elements include an auto shut-off when the tank is full, automatic coil defrost in cold weather, and a digital humidistat display. It has a ‘bucket full’ indicator to let you know it’s time to empty the reservoir, located at the front for easy access. It’s rather tiny – with a 1 gallon tank in a unit that removes 4 times as much moisture from the air. But it redeems itself by allowing you to set up continuous drainage.

It has a wide humidity range, and can work from 35% humidity all the way up to 80%. The fans are also able to function under a wide temperature range, from 41ºF to 90ºF. The fans come in three settings, high, medium, and low. Even in these settings, the unit remains extremely quiet, measuring an operating volume 48 decibels on high and 44 dB when the fan is set on low.

Bottom Line

The quiet function, continuous drainage, and auto restart, paired with the relatively large area of effect, make this the perfect dehumidifier for the basement. You can program dehumidification to happen when you need it to, and you don’t have to keep going down to the basement to check on it.

Haier Energy Star 30-Pint Capacity Dehumidifier with Electronic Controls, White


  • Large area of effect.
  • Compact portable design.
  • Digital humidistat and controls.
  • Full tank indicator with beeping alarm.
  • Easy to access filter with filter check light.


  • Makes a fair amount of noise in comparison.

Our Review

Haier is a well-known brand in the consumer electronics market, and their innovation can be seen in the Haier 30 Pint Portable Dehumidifier. At 20.4× 14.3×10.2 inches and weighing only 28 pounds, this is a small, compact unit. Its sleek lines and visible curves fit in with any modern décor. It’s also very powerful, and rated for large spaces all the way to 2,500 square feet. This makes it one of the better options available for dehumidifying the basement.

You get a digital humidistat with an easy to read display. You also get a single tank, placed in the front for easier emptying. The gadget has a ‘tank full’ indicator that lights up, and a beeping alarm in case you don’t notice the light.

Typically, if you’re running this unit in an area measuring 100 square feet, you’ll have to empty it 3 or 4 times a day. Alternatively, you can set up continuous drainage with the help of a hose. It’s an easy dehumidifier to clean, requiring only a simple wipe-down with a wet cloth.

The unit is designed with mobility in mind, and the small size coupled with the caster wheels make it easier to move from room to room. It comes with 2 fan speeds, and has been known to make a fair amount of noise at its highest setting. This is another feature that makes it perfect for basements and storage spaces, far from residents. It’s ENERGY STAR rated for efficiency, and won’t run up your power bill.

Bottom Line

There are few dehumidifier options in the market today that can match this unit, both in compact size and area of effect. This is a moisture monster that features a powerful fan, and it’s perfect for large damp spaces.

Soleus Air DS1-30-01 30 Pt. Portable Dehumidifier, Pint, White


  • Relatively quiet.
  • Compact portable design.
  • Auto restart with loss of power protection.
  • Auto defrost of the coils and low temperature operation.
  • Easy to operate with simple controls and straightforward functionality.


  • The continuous drainage set-up is complicated.

Our Review

This dehumidifier comes with a digital humidistat and controls, allowing you to program the unit to your liking. You get 3 fan speeds that operate at between 51 and 59 decibels, depending on the speed you set. The Soleus Air DS1-30-01 30 Pt. Dehumidifier also has auto defrost, which allows it to function at lower temperatures of up to 41 ºF.

It has smart auto-restart, which switches the device back on in the event of a power outage. It remembers all the settings when power comes back, so you don’t need to reprogram anything. You also get ‘MyHome’ mode, which is a set of easy-to-use preprogramed humidity levels that mirror common home settings.

Continuous mode sets the unit to run uninterrupted until the auto shut off indicates the tank is nearly full. The tank is capable of storing up to 8.5 pints of moisture at a time, and comes with continuous drainage system. The drainage system might take some time to install, but with a little patience, it becomes an integral part of the machine.

This dehumidifier also comes with the Tri-Pat Certified Safety feature. This is patented technology from Soleus Air that prevents the unit from overheating and arcs in the electrical current. The gadget has a child lock function with an indicator light. This disables the control panel and prevents any unintentional changes to the settings. Another standout feature is the washable antibacterial filter. It works on large air pollutants like dust and pet hair. It also removes odor causing bacteria for better air quality.

Bottom Line

This is a product full of useful features. The patented Tri-Pat technology that prevents overheating is a great addition. It also has a cord wrap at the back to ease the storage of its 72 inch cord.


  • Very quiet.
  • Washable clean filter.
  • Small compact design.
  • Auto shut-off with tank full alert system.
  • Continuous drain and humidity control available.


  • Has only one fan speed.

Our Review

The Frigidaire FAD301NWD 30-Pint Dehumidifier prides itself on simplicity. It’s a quiet unit rated at 53 dB, which is impressive for a machine that removes about 1.25 pints of water from the air. This unit is perfect for spaces that require silence, such as the bedroom, study area, and children’s rooms.

It comes with a Frigidaire anti-bacterial filter to remove dust, pet hair, odor causing bacteria and a host of other airborne impurities. This filter can be removed easily from the unit and cleaned. The cleaning doesn’t require any special equipment, and can be done at your kitchen sink with running water. The controls are manual, with a control dial at the top of the dehumidifier.

You only get one fan speed, but that should be sufficient for most of the rooms in your home even in high humidity. The caster wheels make it a portable unit and the SpaceWise portable design gives you a top handle, with integrated handles on the side. The unit can operate at low temperatures of 41ºF, and this saves you on power.

It’s also ENERGY STAR rated for efficiency, which makes it kinder on the environment. It has an efficient tank full indicator, and an auto shut-off feature when the reservoir gets full. It comes with a 1 and a half gallon tank. The drip bucket is front-loading for easy access and comes with a carrying handle and a splash guard.

Bottom Line

Frigidaire struck gold with this one in terms of function and simplicity. The tank could be larger for a 4-gallon unit, , and you only get one fan speed, but otherwise, it’s a decent machine to buy.

Eurgeen Touch Screen Dehumidifier 4 Gallons (30 Pints) Working Capacity/Every Day, 2nd Generation, with 2L Water Tank, Perfect for Home, Bedroom, Office, Living Room, Bathroom Up to 150-400 Sq Ft


  • Energy efficient.
  • Ultra-quiet when in operation.
  • 3 minute delay for compressor protection.
  • Touch screen controls with humidity sensors.
  • Continuous drainage with hose included at purchase.


  • Relatively small area of effect.
  • Small water tank for a 20 to 30 pint a day dehumidifier.

Our Review

This is a small compact dehumidifier that’s built for small and medium sized rooms. At 10.04×9.65×21.28 inches and weighing 22 pounds, this is a unit that can be put anywhere in the room without seeming conspicuous. It is also ultra-quiet and has been rated at 45 decibels when in operation. That’s about the same amount of noise in a functional library, making the Eurgeen Touch Screen Dehumidifier perfect for bedrooms, study areas, and children’s rooms.

It’s capable of working in spaces of up to 400 square feet. The functionality is dependent on the conditions. For instance, this unit is capable of removing 30 pints of moisture from the air at 86 degrees Fahrenheit and 80% humidity. That number reduces by half in 80 degree weather with 60% humidity.

It comes with a bunch of smart features such as the auto shut-off which kicks in as soon as the tank is full. It also has a clothes-drying mode, which makes use of outgoing air to dry your clothes much faster. It has a 3 minute compressor delay timer, which protects the compressor and extends its durability. Along with an auto shut-off when the tank is full, the Eurgeen Touch Screen Dehumidifier has auto-restart in case of a power outage.

This dehumidifier lets you set up continuous draining, and even comes with the hose included at purchase. The tank is only 1.5 liters in capacity, and can be a bit of a nuisance to continuously empty. But it’s easy to remove, clean, and re-insert, with the entire process taking less than 5 steps. All this is controlled via easy-to-operate touchscreen controls and a superior quality LED readout screen.

Bottom Line

Based on the features and at that price point, Eurgeen offers the best value for money. We loved that it was ultra-quiet, and can be used in the bedroom while you sleep. The built-in clothes-drier function is a nice touch too.

Where Should You Place Your Dehumidifier?

This depends on several factors, such as the size of the dehumidifier, its area of effect, and the condition of the room. Find a spot next to a drain or sink. It should also be close to a power outlet, easing your connection process. Place the dehumidifier in a position with enough room for air to circulate – about 6 to 12 inches of space should suffice.

The hose should be directed away from any electrical appliances and outlets. It should also be kept short, to reduce the possibility of accidents. Keep the dehumidifier away from dust sources such as woodworking equipment or windows that face the street. In smaller spaces, placing the dehumidifier in the middle of the room is advised.

Lastly, always put the dehumidifier in your damp rooms (basement, bathroom, kitchen, laundry room). Using a dehumidifier in the basement is particularly encouraged, since too much moisture could be dangerous for the structural integrity of your basement.


Dehumidification is important. It improves air quality by removing excess moisture and making it lighter and more breathable. It also makes it harder for odor-causing bacteria and mold spores to exist. These require constant moisture in order to thrive. Make sure you have the right dehumidifier for your needs. Remember to check for an ENERGY STAR rating – rated units are up to 15% more energy efficient than unrated ones. With all that in mind, our top recommendation is hOmelabs 1,500 square foot dehumidifier.
