Yet, before you choose your best dehumidifier for small room, here are a few things to have in mind.

  • Bright green light
  • Not suitable for larger space


What’s the appropriate pint capacity?

Pint capacity refers to moisture that a device can remove in 24 hours, expressed in pints. The area size and the level of humidity in the room affect the performance of the dehumidifier. Follow our guide to determine what pint capacity is the best for your needs.

30-pint Dehumidifiers

We recommend choosing a dehumidifier with 30-pint capacity for any room size up to 1500 square feet. The dehumidifier with 30-pint capacity will perform well in this room size, no matter the humidity level. Even if the humidity is high, it will remove moisture efficiently. It is also suitable for the room size up to 2000 square feet when the humidity is moderate. It is suitable for most of the basements.

40, 50-pint Dehumidifiers

These dehumidifiers we recommend to place in rooms of 2000 square feet and high humidity levels. It will remove the visible traces of the mold on your walls and in the corners.

60, 70-pint Dehumidifiers

The 70-pint capacity dehumidifiers come with a large tank. You should empty the tank occasionally. You should use them if your space is larger than 2000 square feet and very damp. Most of them you can install with other draining systems. So, they will obliterate the dampness. They are suitable for damp garages, basements or industrial dehumidifying.

Cubic feet per minute (cfm) or Air changes (ach) per hour?

First, let’s sort out what CFM means. It refers to the amount of air in the room that contains high humidity. You can get that value by multiplying the square footage and ceiling height. Then, look at the humidity level.

The level of humidity determines how many times the air should go through the process every hour. This value is air changes (ACH). The higher the humidity level, the more times it should be in the cycle in the dehumidifying process.

In simple words, if the humidity is high, the air goes more times per hour in the cycle. Before we continue, look at the table of suitable ACH according to humidity level:

The humidity level in the roomSuitable ACH
Damp 60 – 70 %3
Very Damp 70 – 80 %4
Wet 80 – 90 %5
Very Wet 90 – 100 %6

If you don’t have a hygrometer, a device that measures the level of humidity, look at the signs of dampness in your area. If you can barely smell the mildew, the humidity is around 60%. For higher levels, the smell is more intense, and you can spot the evidence of mold on the walls.

If you have moisture in the air and water constantly present, your space is very wet, around 90% – 100%. The level of water you can see determines the ACH. So, more water in the room, higher the ACH.

What and why use one?

As discussed before, small dehumidifiers have 30 pints capacity. If you live in a smaller space, and you have experienced issues with high humidity, a small dehumidifier is your next step. These small units are capable of removing moisture from the air while having a positive impact on the air quality and your health.

You might be wondering how the small dehumidifier concerns with health. Well, a higher level of humidity affects the respiratory system. It can cause common diseases such as flu, cold, etc.

The list of possible negative effects of high humidity is long. It includes skin diseases, allergies, fatigue, lethargy, dehydration, frizzy hair with fuzzy ends, etc.

So, a dehumidifier comes in handy to keep the humidity in balance. So, it will ensure a healthy environment for you and your family. A small dehumidifier is a very practical thing to have around. I remember when I first got one.

There is no unnecessary fuss around it, just set it and forget it. The difference is huge. Mainly on my hair. Jokes aside, keeping the relative humidity at optimal levels is very important. Especially if you or your family members are prone to allergies, and you live in the area with a humid climate.


  • Health benefits – lower risk of respiratory illnesses
  • Furniture and appliances benefits: protects wooden items and electronic devices
  • Fresh environment – removes musty smell and ugly odors
  • Other benefits: prevents corrosion, mold on textile pieces, hair and skin benefits

If you have never owned any dehumidifier, let’s go quickly to the main benefits of having one.

First of all, your environment will become more comfortable. Damp spaces are at higher risk of developing allergens, for example, dust mites in the air. Also, mold and mildew are common residents of wet and damp areas. That can affect the furniture and your health as well.

If you are allergic to mold, you will experience issues such as extensive sneezing, runny nose, etc. after inhaling the mold spores. A dehumidifier extracts the excess moisture from the air, therefore it dries the area. So, the risk for mold and its companions is lower.

On the other hand, if your place has wooden floors or wooden furniture, high humidity can damage it. Having the dehumidifier around in the room will keep your precious furniture protected and damage-free.

Another significant aspect of having a dehumidifier is technology protection. The moisture in the air can cause corrosion on your cables, computer equipment or any tool. At the same time, you won’t have to worry about mold developing at the end of your curtains or your precious linen sheet.

In general, the main benefits of using a dehumidifier include comfortable breathing and a healthier environment. Your home will lose the mildew odor, and start to smell fresh after a short time of using a dehumidifier.

How to dehumidify a small room?

To get the most out of your device, you should follow a simple set of rules. To dehumidify a smaller room use a dehumidifier and follow our steps.

First, you should set the desired level of humidity. Humidity levels around 30-40% are optimal. Set the level you want. Some studies reported that a 45% level of humidity is the most comfortable for the majority of people.

Then, pick the ideal spot for your appliance. To ensure efficiency, leave space around your dehumidifier. Having free space around the dehumidifier is significant due to the air circulating technology. Some devices release the air from the side or the top of the device. So, make sure that you have enabled airflow.

Keep the doors and the windows closed. It will boost efficiency and you will feel the difference sooner.

Don’t forget to empty the water from the tank. The reason behind is simple. If the tank is full, there is no place to put the rest of the moisture. So, the dehumidifier will shut down.

Lastly, keep the tank clean. The dirty filter can decrease performance. Some dehumidifiers have indicator lights to remind you when it’s time to wash the filter. If there is no such feature, you should follow the user’s manual.

Things to consider when choosing

To choose a mini dehumidifier for a single room, you should pay attention to several factors. Those are size, noise, power consumption, user compatibility, design, and moisture capacity. Price, warranty and manufacturer reputation factors are there to make sure you are getting the best value for your money. Also, check the extra features; some of them are very useful.

Design, size, noise

Because you should place your dehumidifier to an open space, it is most likely that it will be visible from any spot in your room. So, try to find the dehumidifier that will fit into your interior style.

So, check how much space you can dedicate to it. If you crowd your room with furniture, look for efficient mini dehumidifiers. Those will take the least space.

Because your dehumidifier will probably run for 20 hours or more, noise is an important factor. Even if you don’t care about the noise level, it is better to go for whisper-quiet dehumidifiers. Those won’t disturb you while you sleep or doing your daily activities.

Power consumption

You don’t want to experience a shock when you get your electricity bills, don’t you? So, check the product description carefully. The best dehumidifiers with pints capacity lower than 70 should have an energy factor less than or equal to 1.90 (L/kWh) (Litres per Kilowatt hour). That determines whether your device is energy efficient.

We recommend you check online for the power consumption dehumidifiers’ calculator for the device you wish to buy.

User compatibility

Some dehumidifiers have wires for connecting with Nest Thermostat. If that is important for you, check if your device with your Nest system. Also, make sure to check whether you can install it, you will need a professional, so that will cost you extra money.

Price and warranty

There are appliances for all budgets. How much money you are ready to spend, depends on your preferences and financial possibilities. Yet, make sure to check the warranty. You don’t want to spend a lot of money, and after a few months to learn that your warranty period has expired.

When you are making a decision in which device to invest, take some time to research the manufacturer’s reputation. Unfortunately, sometimes companies are not the best in treating their customers. Also, some refuse to solve issues with their products. Check for market leaders and companies that value their clients.

Moisture capacity

Before you what is the best dehumidifier for your needs, check your current humidity levels and space. Calculate how much ounces of water you need to remove from your room? How much is your room?

After you answer these questions, you will know whether 30 pints volume dehumidifier will do the work in your room. If not, you need a larger device that can extract more pints of moisture from the air.

Advanced features

Lastly, check for the advanced feature. An auto-shutoff feature is a quite useful and practical safety feature. Others include many settings and indicator windows.
