Best 30 Pint Dehumidifier

Best 30 Pint Dehumidifier Reviews

It’s probably pretty obvious that you need a dehumidifier. Even if you’re not noticing a damp, musty smell, you may see condensation on windows or even black mold creeping across the wall. On a personal level, your allergies are out of control, as is your hair, and you just feel uncomfortable at home. It’s incredible how much a good dehumidifier can help these issues. If you are looking for one that fits all your space and performance needs, stay right here. We have in depth information and reviews on the best 30 pint dehumidifier options on the market today.

Dehumidifiers work by use of a compressor which chills a set of coils. A fan pulls nearby air over the coils, cooling it and causing moisture to condense. The water then drips into a tank. There are other types of dehumidifier, such as one using a desiccant material, but compressor-cooled coils are pretty much standard in units that work at the level you need. You may select a 30 pint dehumidifier for basement, bedroom, living room, etc., but this size is usually not enough to cover more than one room at a time.

The 30 pint designation for dehumidifiers is slightly confusing, because it doesn’t refer to how much water the unit can hold, but to how much moisture can be pulled from the air over a 24 hour period. However, humidity levels fluctuate from day to day, and certain conditions make it more difficult for the unit to work at its peak. On drier days, your dehumidifier may not pull anything close to 30 pints.

A 30 pint dehumidifier is ideal for people who have moderate humidity yet not a ton of space. For very large homes, we would recommend a whole house dehumidifier that can be hooked into your existing HVAC ducting. For very small spaces that are just extra humid – like the bathroom – you’ll want to look for the best small dehumidifier. There are units that are much more compact and fit better in a tight space, but they often don’t have compressors and can’t match 30 pints per day.

What makes a 30 pint dehumidifier an ideal option for spaces from about 1,000 - 2,000 square feet is that they have a nice capacity while also being highly portable. Generally lightweight, they are also mounted on casters to allow for easy rolling. This may be the best choice if you need to move your dehumidifier from room to room, depending on the conditions.

Reservoir sizes vary and not all will hold a day’s worth of water. However, many 30 pint units, despite being compact, offer a drain hose option that allows you to direct water right down a floor drain or into a utility sink. If your dehumidifier is for the basement – often the muggiest part of a home – this allows you to set up the unit and basically forget it.

Features to Consider in a Dehumidifier

The features available in dehumidifiers today are many. Following are some things to consider when deciding which model will work best for you.

User-Friendly Controls

Some dehumidifiers are simply turned on with little opportunity to customize the settings. But others have a range of features that allow you to set a specific preferred humidity level or program a timer function. You’ll want to look for a unit that has easy to understand controls, rather than requiring a certain number of presses of one button for all features.

Auto Restart

If your humidifier is in a place that you don’t visit very often, like a basement or even a vacation home, auto restart will turn the dehumidifier back on after a power outage. Since resetting the dehumidifier probably won’t be your first thought after the lights return, this job can easily slip your mind.

Pump and Hose Connection

Emptying a full dehumidifier is a chore you’ll need to do several times a week. If you forget to check on your dehumidifier, it’s just going to sit there full and not do its job. To make this easier, some dehumidifiers have pumps that can be used in conjunction with a hose to divert condensed water away from your living space and drain elsewhere. This might be down a floor drain, but with a pump, you can push water up into a utility sink or even out a window. If you use a window, just be certain that water will flow away from the home and not back into your foundation.


A timer can be a useful feature if you’d like your dehumidifier to work mainly during the most humid hours of the day or night. Perhaps you only want it on when you are home, or not home. You could also save money by using it only during off-peak hours when electricity is more affordable.

Frost Sensor

Because the refrigerated coils on a dehumidifier are always cold and wet, sometimes they will frost over. Some models include a sensor to turn off the machine if this occurs. In a frozen state, it becomes incapable of pulling moisture from the air and will only waste electricity if it continues to run. With a frost sensor, the compressor is turned off to allow the coils to warm and melt the ice crystals. Sometimes the fan continues to run in order to speed up this process.

Washable Air Filter

Most 30 pint dehumidifiers also have an air filter that helps to keep the air clean. A dirty air filter makes the unit work too hard to pull air through it, and can lead to a burned out motor. If you choose a dehumidifier with a washable filter, it’s easy to remove and clean every so often to keep the unit working optimally. It also saves the cost of buying replacement filters.

Easy-to-Empty Bucket or Tank

Unless you are going to use a drain hose, you’ll want a containment bucket that is easy to empty. Water is pretty heavy, so the tank should have a carry handle or other grips that make it possible to get over to the sink or out into the garden without spilling. Water that hits the floor is water that will evaporate back into the air!

Now that you have a sense of what you’re looking for, let’s work on selecting a dehumidifier that meets all your needs and wants.

Why a Dehumidifier is Critical

Keeping your space at an ideal humidity level is crucial to health, comfort, and overall home maintenance. A dehumidifier helps in the following ways.

Decreases mildew, mold, and allergens

Mold anywhere in the home is unpleasant to both look at and smell. It tends to make a space feel dirty, no matter how much you scrub, because mold can hide in the tiniest of cracks and then easily regain its foothold. Mold in the home has been tied to many health issues, including asthma, respiratory infections, and allergic reactions. Some of the issues can even stick around long after you are no longer exposed.

If anyone in the home has allergy issues, a dehumidifier is a must. Excess moisture holds pollen and other irritants in the air where they can be easily breathed. You may find that simply running a dehumidifier in your bedroom or living room diminishes seasonal allergies considerably.

Mold anywhere in the home is unpleasant to both look at and smell. It tends to make a space feel dirty, no matter how much you scrub, because mold can hide in the tiniest of cracks and then easily regain its foothold. Mold in the home has been tied to many health issues, including asthma, respiratory infections, and allergic reactions. Some of the issues can even stick around long after you are no longer exposed.

Protects both the contents and the structure of your home

Excessive moisture can lead to all sorts of damage. Walls begin to degrade and tile can loosen. Mold can also eat away at the building materials that make up your home. It will damage wood, walls, ceilings, and floors, eventually causing structural instability. Mold also grows very quickly, and can easily make its way throughout a home if not stopped.

Soft surfaces like furniture and clothing are not exempt from water damage, so failing to control the humidity level in your home is likely to cost you a lot more than the price of a 30 pint dehumidifier in repairs.

Keeps your air fresh and your body comfortable

Not only does a dehumidifier keep air circulating, it also pulls dust and other particulates along with water. That leaves the inside air quality much cleaner and fresher, eliminating musty, stagnant odors. But beyond that, we all know what it feels like to be oppressed by excess humidity. It’s that swollen, too hot feeling, with hair that frizzes out around your head and keeps sticking to your face. The right dehumidifier can help you feel cooler at home, even if the outside temperatures are high. Humidity greatly affects our experience of heat.

Maintaining Your Dehumidifier

The work needed to keep your dehumidifier in top shape has a lot to do with the features it offers. Units that use a compressor have more moving parts that are prone to breaking down if not properly maintained.

Keep it Clean

Maintenance of your 30 pint dehumidifier starts with basic cleaning.

Air Filter

All of the dehumidifiers on our list have reusable air filters that need to be cleaned or replaced when they get dirty. A dirty filter can’t do its job of purifying air, and forces the machine to work very hard with poorer results. Air filters also vent air that is fresh and free of allergens and dust particles – arguably one of the most important functions of the device.


All electric dehumidifiers use a fan to pull in damp air, run it over coils, and then exhaust drier, hotter air. Dust and floating debris gets sucked in along with the air and often builds up on intake and exhaust vents. When these passages become clogged, the motor struggles to get enough airflow, which leads to burnout. Dusting out the vents frequently helps to keep your dehumidifier going strong.

Water Collection Tank

You know you need to empty the water collection tank when it’s full, but may forget to clean out the inside every so often. The water that is collected by the dehumidifier is considered greywater, not suitable for drinking but great for plants. Knowing that it is not clean enough to consume should clue you in to the fact that there is stuff in there that can grow on the inner surfaces of that collection tank.
Use dish soap and water or even just a disinfectant wipe, but don’t skip this step. Mold and mildew can grow in moist environments – this is part of why you bought the dehumidifier in the first place. Unfortunately, the unit itself is also just as prone to growing yucky stuff when it is left in a damp condition constantly. Unless you want to wear a mask when emptying it, spend a few minutes to keep it clean.

Check Connections

As with any machine, the internal components must be properly attached to work efficiently, or in some cases, at all. Checking out all the various working pieces of your dehumidifier can help you determine whether it is functioning at its best. Sometimes it can seem like the unit is running, but it may not be pulling as much moisture as it could.


Dehumidifiers with coils don’t work very well in cold temperatures. Several of the models on our list have features that help to defrost the coils when they get frozen, or avoid having them freeze at all. Some dehumidifiers have a hot gas component that thaws out frozen coils, but most do not. Repeated freezing and thawing of the coils can damage them. Similarly, coils that come unseated due to frequent movement won’t work very well. Sometimes loose coils can be reseated by hand, but it’s safer to have them checked out by a professional.

Electric Cords

Electric cords have delicate wires inside their rubber coating, and these are broken easily by repeated bending or pulling. Cords that are damaged don’t work efficiently and can be very dangerous to use. Cheaper electronics don’t have a power cord with connections at both ends because the manufacturer wants you to replace the whole unit. But if your dehumidifier has the handy ability to completely detach the cord, it is relatively easy to buy an aftermarket replacement. To avoid needing to replace the cord at all, ensure that it stays out of the way (so that it won’t be tripped over), and rests with some slack in it to protect the wires inside.

Buy New to Save Money

When purchasing a dehumidifier, you need to consider more than the upfront price of the unit. Operating costs will add significantly to that number over the life of the machine. It may be tempting to buy a second-hand dehumidifier in order to save some money. But due to new federal energy standards, older dehumidifiers are not nearly as energy efficient as newer ones. Operating costs can be steep depending on how often you need to run your dehumidifier, so we recommend buying new to save significant money on electricity. It’s also important to be able to read the dehumidifier reviews available online for any model you might purchase.

Fix Existing Problems

Most 30 pint dehumidifiers do a great job with atmospheric humidity, but they can’t handle excess moisture that comes from a leak. If you have structural problems that allow water to flow where it shouldn’t, these issues must be fixed before a dehumidifier can really do its job.

Make sure to unclog gutters and position the downspouts so that they direct water at least three feet away from the house. Examine all showers, baths, and toilets, as faulty seals can cause dripping onto and through the floor, which creates water stains on the ceiling below and creates the perfect environment for mold to grow. Cracked sealant around windows not only gathers condensation, it also pushes heating and cooling costs through the roof.

You should now be in great shape to choose the best 30 pint dehumidifier to meet the needs of your space. This size is best as a one room dehumidifier, and may need to be emptied more than once a day if the humidity is especially high. Most come with casters to make it easy to move your machine from room to room, but you might consider buying several, or at least one for each floor in your home. One thing is for sure, you will absolutely notice the difference in comfort and air quality once you get a dehumidifier running in your home.
