Editor’s Choice: Frigidaire Small Room 30 Pint Dehumidifier

frigidaire small dehumidifier


Surprisingly small dehumidifiers vary by size and capacity. This Frigidaire, although bigger than the other ones on our list, is our favorite because it holds the most water. It can also work for a big enough space without taking up tons of space. While the name says it’s designed for a small room, the reviews indicate that this Frigidaire could work to remove the moisture in a living room or even in a tiny small apartment.

This Frigidaire dehumidifier also works well because it gives you the option to either drain it continuously with a hose or manually dump the 30-pint container once it’s filled with water. The wheels make it easy to transport to various rooms if you need to, although we wouldn’t call this the most portable option. Overall, this dehumidifier wins for the most powerful, high capacity option that won’t take up too much space in your home.

Frigidaire Small Room Dehumidifier Pros

  • Drain option- You can choose between the continuous drain option or dump the water tank once it’s full.
  • High capacity for small dehumidifiers– Although big, this small room dehumidifier holds the most capacity so you can use it for weeks before emptying it out.
  • Easy to clean, removable filters– Lower the bacteria in your air by easily cleaning out the filters in the dehumidifier.

Frigidaire Small Room Dehumidifier Cons

  • Not suitable for RVs– The dehumidifier weighs about 34 lbs and is about 14 inches tall, but it’s still compact enough to fit in a bedroom, basement or small living room. However, it is not suitable for RVs.
  • Pricey– This is one of the more expensive models, but you’ll be getting your money’s worth.

There are a ton of great small dehumidifiers that would we work in an RV, but we love the Eva Dry 333 because of its design that makes it optimal for your small RV.

  • Powerless design- It works without any power, making it perfect for an RV.
  • No spills or water reservoir- Absorbs the moisture in the air through its beads, so you don’t have to empty out the container ever.

Dehumidifier’s Capacity

From the small, mini dehumidifiers to the big industrial ones, every unit has its own capacity. It’s important to assess the type of capacity that you’ll need for your home. The capacity usually correlates to the amount of coverage your dehumidifier will reach as well.


The smaller the dehumidifier, the less coverage it has and the less amount of water it can hold. This means that if you place a dehumidifier in a large room that’s pretty swampy, it won’t be as effective. Small dehumidifiers are usually great for small, damp spaces like kitchens, bathrooms, and RVs. If you are looking for a unit that will cover a larger space than that, you’ll have to get a bigger, more powerful unit.

Most “small” dehumidifiers can hold around 15 oz. to 2 liters of water, but it really depends on the model. Some brands, like Frigidaire, label their units as small, but the unit holds up to 30 pints, which is around 14 liters. In most cases, a small dehumidifier can have a capacity as small as 14 ounces.


Medium-sized dehumidifiers can hold around 50 liters of water. This is more suited for large rooms, or even a spacious studio apartment that gets really swampy. If you need to dehumidify your entire home, you may want to opt for a larger capacity dehumidifier.


Large capacity and industrial level dehumidifiers are extremely powerful and have the biggest coverage out of all of the sizes. You’ll be looking at at least 70 ounces of water, and usually with a continuous drain system in place to keep maintenance down. Large dehumidifiers are the perfect option for drying out flooded homes, large humid basements, or keeping the mold out of your entire home.

Benefits of a Small Dehumidifier

As you can see, there are tons of different humidifiers you can get depending on the size of the space you need it for. However, there are a few advantages of choosing a smaller dehumidifier, besides removing the moisture from the air and getting rid of bacteria.

Smaller Spaces

A compact size allows you to place your dehumidifier just about anywhere. The small size makes it great for apartments or rooms that don’t have much space to spare. Need to put it in your bathroom, but don’t have much counter space? You can use the small size to your advantage while still lowering the humidity levels in your home. You’ll be surprised by the difference these small machines make in even the dampest places.

Increased Portability

The best small dehumidifiers are lightweight and small and make it easy to transport around your home. Most of these mini dehumidifiers are under 5 lbs, making them extremely portable. If you need to alternate rooms with your dehumidifier, or even travel with it, having a small size makes it portable.

If you opt or a medium-small sized unit instead of the mini dehumidifier, it’s best to look for one with wheels. These units, like the Frigidaire small room dehumidifier, aren’t great for travel, but their build makes them portable. At least around the house.

Lower Noise Level

With any type of home tech gadget, the amount of noise it makes it important. Whether you’re placing it in your bedroom or an office, a loud machine will not only disturb you, you’ll also be less likely to use it. The great advantage of using a small dehumidifier is the reduced noise level.

The smaller, higher quality units should run smoothly and quietly, you shouldn’t even notice they are on. This is especially important because most people run their dehumidifiers all day long. Look for a dehumidifier that is made with Peltier( thermo-electro cooling) technology, which is an advanced technology that the best small dehumidifier will have to keep it quiet.

Lower Price

These machines can be pricey, and no one wants to go broke paying for something that is a necessity for many. Small dehumidifiers are great because most of them, even the best ones, are under $50. The affordable price and the durability make the smaller units an attractive choice for many. Of course, there are pricier options out there, but its comforting knowing you don’t have to spend that much to get a good product.

Small Dehumidifier Buyer’s Guide

Here are a few of the specifics to look at when shopping for a new small dehumidifier. These are all of the components that you should consider regarding the features.

Ease of Use

Ideally, a small dehumidifier should be extremely easy to start using once you open the box. If you’re getting a compact size dehumidifier, make sure the steps to use them are as minimal as possible. Most of them are easy to use, you simply plug them in, and empty out the water reservoir once it has reached capacity.

Anything more than this should just be regarding cleaning and maintenance. It’s best practice to read the user reviews and manufacturers details to make sure it’s a simple process.

Power Consumption

Most people run their dehumidifiers all day and night, especially if you live in a particularly damp home. Because of the constant use, the amount of energy you’re using should be a big concern. To avoid high electricity bills and a negative impact on the environment, opt for an energy efficient machine. The lower the watts, the less energy it consumes.

Auto Cutoff and Auto Restart

Most small dehumidifiers are designed to auto stop and start once the tank is filled. This ensures that you don’t have any spills or leaks once the reservoir has reached its capacity. Once it cuts off automatically, a light will come on to alert you to empty it. Some machines have auto restart as well, which is good so you don’t have to remember to turn it on again.

Some of the high tech dehumidifiers are wifi enabled, which allows you to control it through an application on your phone. This feature is extremely convenient, however, it’s usually available in bigger, heavy duty units.

Frost Sensor

Most dehumidifiers only work within a certain temperature range. Dehumidifiers cannot operate below temperatures of 41 degrees Fahrenheit. If they do, the metal coils that pull in the water in the air will start to frost over, and your machine will not function properly. Once the coils are frosted and you continue to use it, this will further damage the machine even further.

Quality brands like Frigidaire will have a frost sensor that will let you know when the metals are freezing the water. To prevent this from happening and damaging your machine, avoid using the machine in lower temperatures. Proper maintenance and cleaning will also prevent this from happening.

If your dehumidifier doesn’t have a frost sensor, then check to make sure your machine isn’t making more noise than usual or producing less water.

Noise Levels

As mentioned above, smaller dehumidifiers tend to run more quietly than their big counterparts. Thoroughly check the user reviews and the manufacturer manual to see if it runs quietly before buying. Generally, you’ll want to go with one that is made with Peltier or thermo-electro cooling technology. This means the machine has no moving parts and almost emits no sound at all.

Water Tank Capacity

Unfortunately, your small dehumidifier won’t be able to hold that much water, which means you’ll have to switch it out every few days. The typical water tank capacity range is usually around 14 ounces to a couple of liters. The tank capacity depends on the manufacturer as well, some brands only offer small, 30-pint capacity tanks. Generally, you should be fine with a water tank capacity of about 15 ounces. You just need to make sure you’re okay with dumping it out often.

Cleaning and Maintenance

Like any other appliance or home gadget, you’ll need to clean and upkeep your small dehumidifier. Luckily, this process is usually easy to do. The standard compact dehumidifier will be fairly easy to clean and maintain, as the only parts included are the water tank. Bigger dehumidifiers may require you to clean their filters out. Make sure these parts are easily washable so you can avoid the hassle or a damaged machine.


The standard amount of warranty you’ll get is 1 year for your small unit. For specific warranty time, check the individual manufacturer information, as this can vary. Some brands will offer a longer warranty, and some will offer a longer warranty on specific parts.

In short, you’ll need a dehumidifier for your home if you live in a damp building that is prone to mold. Believe us when we say that investing in these powerful machines will save you a world of uncomfortable issues. You won’t have any gross mold, mildew or pesky health issues when you soak up all of the moisture in your home. We hope our buyer’s guide helped narrow down the best small humidifier for you.
