The best way to get rid of the dampness in any room in your home is by investing in a small dehumidifier.
A small dehumidifier will remove the gross wet air from any room in your home without taking up too much space or making too much noise.

Editors' Choice: Frigidaire Small Room 30 Pint Dehumidifier
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.
This dehumidifier can 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 remove the moisture in a living room or even in a small apartment.
This Frigidaire dehumidifier also 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 Cons
- High cost: This is one of the more expensive models, but you’ll be getting your money’s worth.
- Not suitable for RVs: The dehumidifier weighs about 34 lbs and is about 14 inches tall. It’s compact enough to fit in a bedroom, basement, or small living room. However, it is not suitable for RVs.

Get rid of the uncomfortable stickiness in your bedroom by using this Ivation Powerful Dehumidifier.
The size is ideal for a bedroom, especially if you have a lot of wooden furniture or things that can be damaged by the humidity. Don’t be fooled by the name. “Mid-size” doesn’t mean this humidifier is too big.

Best for Bathroom: Pro Breeze Electric Mini Dehumidifier
Bathrooms are usually some of the most humid parts of a home, which makes them a breeding ground for mold and mildew growth.
Bathrooms are also small, which is why it’s helpful to have a dehumidifier that is compact yet powerful.
Pro Breeze brings you a powerful and effective way to remove the moisture from the air in your tiny spaces. We think this one is a perfect option for bathrooms and other small, humid areas.
The unit can easily fit against a wall in any space or corner in your bathroom, and within a day, you’ll notice the difference between how your bathroom feels.

Best for RV: Eva Dry 333 Renewable Mini-Dehumidifier
There are many excellent dehumidifiers that would work in an RV, but we love the Eva Dry 333 because of its design.
The Eva Dry 333 is a wireless mini dehumidifier that doesn’t need to be dumped every few days. Instead, it collects the moisture in the air via its moisture meter crystals that last about 3-8 weeks.
You can keep this in your RV for your long trips and don’t have to worry about dumping any water out while you’re traveling. When the beads turn green, it’s time to renew them. Once they are green, take the dehumidifier to a power source until it’s fully charged.
The only downside to this mini-dehumidifier is that it does take quite some time to regenerate its battery life. Some people buy a pack of two to use while one is charging.
Eva Dry 333 Renewable Mini-Dehumidifier Pros
- Powerless design: This humidifier works without any power, making it perfect for an RV.
- No spills or water reservoir: The device absorbs the moisture in the air through its beads. You don’t ever have to empty the container.
Eva Dry 333 Renewable Mini-Dehumidifier Cons
- Long recharging time: Recharging tends to take hours.
From the mini dehumidifiers to the big industrial ones, every unit has a different capacity.
The capacity also usually correlates to the amount of coverage your dehumidifier.
Assess the capacity you’ll need for your home.
The smaller the dehumidifier, the less coverage it has and the less amount of water it can hold.
If you place a small dehumidifier in a large, swampy room, it won’t be as effective. Small dehumidifiers are better for small, damp spaces like kitchens, bathrooms, and RVs. If you are looking for a unit that will cover a larger area 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 depends on the model.
Some brands, like Frigidaire, label their units as small, but the device holds up to 30 pints, which is around 14 liters.
In most cases, a small dehumidifier can have a capacity as little as 14 ounces.
Medium-sized dehumidifiers can hold around 50 liters of water.
This size is best suited for large rooms or even a spacious studio apartment that gets swampy.
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. This size usually has a continuous drain system in place to keep maintenance down.
Large dehumidifiers are the perfect option for drying out flooded homes, dehumidifying large basements, or keeping the mold out of your entire home.
Benefits of a Small Dehumidifier
There are a few advantages to choosing a smaller dehumidifier.
A compact size allows you to place your dehumidifier almost anywhere.
The small size makes it helpful 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.
The best small dehumidifiers are lightweight, making it easy to transport around your home.
Most mini dehumidifiers are under five pounds, making them extremely portable. If you need to alternate rooms with your dehumidifier or even travel with it, having a small size is convenient.
If you opt or a medium-small sized unit instead of the mini dehumidifier, look for one with wheels. These units, like the Frigidaire small room dehumidifier, aren’t best for travel, but their build makes them portable around the house.
Lower Noise Level
With any 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 disturb you, and you may be less likely to use it. One 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 fact is important because most people run their dehumidifiers all day.
Look for a dehumidifier that uses Peltier (thermo-electro cooling) technology, which is an advanced technology that helps the device stay quiet.
Dehumidifiers can be pricey, and no one wants to go broke paying for something that is a necessity for many.
Small dehumidifiers help 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.
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
When you’re shopping for a dehumidifier, there are a lot of factors to consider.
Use our buying guide to help you identify the features that are most important to you.
Auto Cutoff and Auto Restart
Most small dehumidifiers are designed to auto stop and start once the tank is full.
This feature ensures that you don’t have any spills or leaks once the reservoir has reached its capacity. A light will come on to alert you to empty it.
Some machines have auto restart as well, which is helpful because you don’t have to remember to turn it on again.
Some of the high tech dehumidifiers are also 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.
Cleaning and Maintenance
Like any other appliance or home gadget, you’ll need to clean and upkeep your small dehumidifier. Luckily, this process is easy.
The standard compact dehumidifier will be easy to clean and maintain because the only parts included are the water tank. Bigger dehumidifiers may require you to clean out the filters.
Make sure these parts are easily washable so that you can avoid the hassle or a damaged machine.
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 dehumidifier, make sure the steps to use them are as minimal as possible. Most are easy to use. You plug them in and then empty the water reservoir once it reaches capacity.
Read the user reviews and manufacturer’s details to see how easy the device is to clean.
Most dehumidifiers only work within a specific temperature range.
Dehumidifiers cannot operate below temperatures of 41 degrees Fahrenheit.
If the temperature is lower, the metal coils that pull water from the air will frost over, and your machine will not function properly. If the coils are frosted and you continue to use the machine, you’ll damage the humidifier.
Avoid using the machine if you’re experiencing low temperatures and maintain your device to prevent problems.
Quality brands like Frigidaire will have a frost sensor that will let you know when the metals are freezing the water.
If your dehumidifier doesn’t have a frost sensor and the weather is getting colder, make sure your machine isn’t making more noise than usual or producing less water.
Smaller dehumidifiers tend to run more quietly than their big counterparts. However, there may be exceptions.
Generally, you’ll want to go with a machine that has Peltier or thermo-electro cooling technology. This feature means the device has no moving parts and almost emits no sound at all.
Check the user reviews and the manufacturer manual to see if it runs quietly before buying.
Most people run their dehumidifiers all day and night, especially if they live in a particularly damp home.
Because of the constant use, the amount of energy you’re using may be a 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 power it consumes.
Water Tank Capacity
Your small dehumidifier won’t be able to hold that much water, which means you’ll have to switch it every few days.
The typical water tank capacity range is usually around 14 ounces to a couple of liters. The tank capacity also depends on the manufacturer. Some brands only offer small, 30-pint capacity tanks.
Generally, you should be fine with a water tank capacity of about 15 ounces as long as you’re able to dump it frequently.
The standard amount of warranty you’ll get is a year for your small unit.
For specific warranty information, check the product. 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.
Investing in these powerful machines will save you a world of uncomfortable issues. You won’t have mold, mildew, or pesky health issues when you soak up all of the moisture in your home.
