2) SereneLife Compact Free-standing Portable Air Conditioner 

Special features

The SereneLife Compact Free-standing Portable Air Conditioner is a powerful and versatile air conditioning unit that can cool a room up to 300 square feet. With a cooling power of 10,000 BTU (ASHRAE) / 6,000 BTU (SACC), an airflow rate of 360 cubic meters per hour, and a built-in dehumidifier, this unit can effectively reduce humidity levels while keeping the air cool and comfortable. The unit features three operating modes – cooling, dehumidifier, and fan – and a remote control for easy temperature and fan speed adjustment. Its sleek and modern design, with rolling wheels and a free-standing body, makes it easy to move around and use in any room.

My second pick for closed room coolers is the SereneLife Compact Free-standing Portable Air Conditioner 

One of the best features of this AC is its portability. It is designed with rolling wheels, making moving from one room to another easy. It also includes a window mount kit, perfect for those living in apartments or other rented spaces. The unit can be easily installed in a window and removed when not in use.

3) Evapolar evaLIGHT Personal Evaporative Air Cooler 

Special features

If you are looking for the most portable devices that come with the coolest designs, then you are absolutely on the right track, though the final puzzle piece should be that you intend to use it in a small space. This device looks appealing, adding beauty wherever it is used, and functions in the background without consuming much energy. This Evapolar device is also practically bacteria-resistant.

My third pick for the best air coolers for closed rooms is the Evapolar evaLIGHT Personal Evaporative Air Cooler 

It is designed to be more suited to tabletops, like placing it on your office desk or bedside, and only requires as little as 10 Watts of power to run. This means it can be connected to a computer or UPS asides from the standard power outlet socket. Despite its tiny dimensions, I was very impressed by how well it worked to cool down my room.

However, the disadvantage of a dwindled capacity exists too. The feature that stands out the most in this device is its resistance to any form of bacteria spread. When bacteria gets to the filter of any cooler, it becomes a significant problem and a question of replacing the filter. The filters are usually challenging to get to. This device uses specially designed patented non-organic evaporative pads, which prevent bacteria from spreading, eliminating the stress of going through any of those problems in the first place.

It also acts as a humidifier and air cleaner asides from its cooling ability and is very cheap to run due to consuming only 10W of power. However, it is a little bit loud while running, which I found somewhat of a nuisance. On the other hand, the noise is a small price for this cooler’s mobility. Although it works very well for a bedroom, I wouldn’t count on it effectively cooling down a bigger area. 

What I Like

  • Portable and lightweight
  • It can act as an air cooler, air cleaner, and air humidifier
  • The design prevents the spreading of bacteria
  • Energy-efficient – consumes only 10W of power
  • Minimalistic, modern design
  • Can be powered by USB or power bank

What I Dislike

  • A bit loud
  • It can’t be used in bigger areas
  • Limited performance capacity

4) Arctic Air Tower 2.0 Evaporative Air

Special features

The Arctic Air Tower 2.0 Evaporative Air Cooler is a great solution for those looking for a portable, easy-to-use air cooling system. With its sleek design, this tower air cooler is perfect for any room in your home, office or dorm. Its evaporative cooling technology adds moisture to the air, which then cools the surrounding area, making it a more comfortable environment. It has three different fan speeds, which allows you to adjust the airflow according to your preferences.

My forth pick for closed rooms coolers is that Arctic Air Tower 2.0 Evaporative Air

The Arctic Air Tower 2.0 Evaporative Air Cooler is a portable cooling solution perfect for small to medium-sized rooms. Its slim tower design takes up very little space, making it easy to move from room to room. The air cooler uses evaporative cooling technology to cool the air, which is a more energy-efficient and eco-friendly option than traditional air conditioners.

One of the standout features that I liked is its easy-to-use touch controls. The cooler’s digital display allows you to adjust the fan speed, set a timer, and turn on the oscillation feature. A remote control is also included, making it convenient to adjust the settings from across the room.

Another great feature of the Arctic Air Tower 2.0 is its multi-stage air filter. The cooler uses a combination of a pre-filter, HEPA filter, and activated carbon filter to capture allergens, dust, and other airborne particles. This is especially useful for people with allergies or respiratory issues, as it can help improve the air quality in the room.

Regarding cooling performance, the Arctic Air Tower 2.0 greatly lowers the temperature in small to medium-sized rooms. It has a powerful fan that can circulate the cool air throughout the room, and the oscillation feature helps to distribute the cool air more evenly. The cooler also has a water tank that can hold up to 1.5 liters of water, which is enough to last for several hours before refilling.

What I like

  • A cost-effective solution for keeping your space cool during the hot summer months.
  • Easy to move around your home or office, so you can enjoy cool air wherever you go.
  • Simple to operate with intuitive controls and remote control
  • It also functions as a humidifier and air purifier
  • Energy-efficient:

What I Dislike

  • Requires Regular Maintenance like cleaning the water tank, filter, and other parts
  • It has limited cooling capacity compared to traditional air conditioning units

5) Evapolar evaCHILL Personal Evaporative Air Cooler 

Special features

This cooler proves that the Evapolar evaChill series always has unique designs. It is very good looking, with LED light glow by the side giving a suiting night light for users who fancy one. It is handheld, portable, and consumes minimal energy, which would not add to your energy bills.

my final pick for the air coolers that i recommend to use in closed rooms is the Evapolar evaCHILL Personal Evaporative Air Cooler

This device is also an evaporative cooler, which uses a fan to blow water off a filter until it evaporates and cools the air. Its filters are designed with a non-organic material, which means bacteria and other contaminations that thrive in moisture wouldn’t be able to grow on it. From my experience, it is also a 3-in-1 device because it can be used as an air conditioning fan and air cleaner besides its primary air cooling function. Converting these many functions into one makes it a cost-effective device at a very reasonable price.

However, it is suitable for only tiny spaces because it cools the immediate atmosphere around it (I recommend a maximum of 45 square feet). Despite its relatively small size and water tank, I found it can run for about 9 hours in total before requiring a refill, and it works very quietly compared to the other Evapolar air cooler. It consumes precisely 7 watts, less than a lightbulb, for virtually zero running cost. I admit it is quite fragile and should be handled with care.

What I Like

  • It’s a handheld, lightweight, and highly portable device
  • I can use it for numerous purposes: air cooling, cleaning, and humidifying
  • It has quite a long running time (up to 9 hours)
  • It doesn’t consume too much energy
  • Easy to operate (with just 1 button)
  • I can use it as an additional light source

What I Dislike

  • It covers only a small area
  • It seems a bit fragile to me
  • No remote control

What to know about the closed room and its ventilation

Because the room is closed literally, air fails to circulate properly, leading to stale air being present most of the time. Over time, the air could start to smell moist and stuffy, and we all know that all in that category isn’t any way comfortable to breathe in. Poor ventilation in closed rooms also leads to an ever-present warm or hot temperature, which is undoubtedly uncomfortable. Thick stagnant air and warm temperatures can make falling asleep more suffocating than relaxing. In a nutshell, closed rooms mostly have poor ventilation, so I find air coolers especially helpful.

Room cooler vs. air conditioner in a closed room

A room cooler and an air conditioner basically serve the same purpose: to reduce the room’s temperature level. However, they go about it differently and have slightly different outcomes. The air conditioner is a device that reduces temperature by circulating internal air in the room repeatedly, taking the hot air outwards, and replacing it with a cooler one. They are instrumental in cooling, far more effective than coolers, but always leave the air drier than anyone would want. Some have used a humidifier alongside this device to solve the problem.

On the other hand, air coolers operate in a very different way, creating coolness through the evaporation of water. Hot air is blown on a water-absorbing filter, causing it to evaporate and cool the atmosphere. They need water to cool, and for more effect, you can always add ice cubes – from my experience, it’s a really handy hack.

Air conditioners are more effective than coolers; however, their dry atmosphere is unhealthy and promotes the spreading of infections that thrive in such conditions, compared to air coolers that add moisture to the room. Air conditioners are also more expensive but require less attention than coolers. I’ve experienced that for an air cooler, it must frequently refill its water instead of just letting it run wild like the air conditioner. Air conditioners also have a negative effect on the environment, especially if the refrigerants used in cooling get out into the air. They are not as portable as coolers and would attract special installation costs. Also Read: Best Air cooler for Humid climate

How to choose an air cooler for a closed room: Appropriating sizing

The way I do it and what I recommend if you want to choose the best air cooler for your closed room is by looking out for its airflow rate measured in CFM (cubic feet per minute). This value shows how much air is cycled in a room per minute. In order to know the right CFM for your room, first calculate the area in square feet, then multiply by height and then divide by 2. For example, in a room of 200 sqft and height of 7ft, CFM required would be (300 sqft x 7ft) / 2 = 700 CFM. This means that the most effective air cooler for your room is a 700 CFM, though coolers with lower capacity might do just fine. They can’t be just as effective, though.

How do you cool a closed room with an air cooler?

When living in a closed room, placing an air cooler in the same room would be nothing short of discomfort over a short period of time. Trust me! This is a result of the fact that coolers also add humidity to the atmosphere. When there is no cross ventilation for moisture exchange, the air becomes oversaturated with moisture. Therefore, placing an air cooler in an external spot outside the room or in a window where it fits perfectly is best.

Features to Consider When Choosing Best Air Cooler For Closed Room

A bedroom is a place where maximum comfort is felt in the home, which makes it essential to keep it as comfortable as it can be all year long. One of the necessary gadgets to get this done is the best air cooler for closed bedrooms. It is also essential to consider the space consumption in a bedroom since they aren’t correctly built to be spacious, which is why this same product should also satisfy the best small air cooler criteria.  From my experience, these are the features you should pay attention to when choosing the best air cooler for a closed room:


Since we are considering air coolers for closed-sized rooms, which mostly have a small capacity, the category of devices reviewed in this article is all tailored to fit medium-sized rooms at best. If your room is of a larger size, purchasing an equivalent capacity device that can effectively cool the place is your best bet.

Ease of Use

Convenience features in air coolers include a user-friendly digital control panel, which could come with a display screen for more ease. The remote control feature is also nice, allowing users to vary the device’s performance from a distance and change the mode in which it operates.

Multi-Purposed Device

If you read carefully across the review articles, you will discover that no device exists as an air cooler alone. I definitely recommend purchasing devices that are air coolers and more for maximum cost-effectiveness. Some extra features an air cooler can have without much stress include a humidifier, fan, and air cleaners.

Oscillatory Design

Devices with oscillatory functions either rotate physically or contain internal glides which change directions at the interval, varying the direction of air released and covering a more substantial area per time than stationary air coolers. This gives it a cooling effect for multiple users at different locations in the room.


From my experience, I can say that air cleaners are usually bulky in size and kind of heavy, especially when with a full water tank. However, they remain portable if they have wheels for users to roll them with. If you intend to move your air cooler frequently, then be sure to get one with this feature:

Ice Compartment Chamber

The ice compartment does just one job in the cleaner: adding a cooler to the evaporated water molecules. With this chamber, one can easily reduce the temperature of cold air released, reducing overall temperature faster. It is especially useful in warm weather conditions.

Final Verdict: Which cooler is best for closed room

The best product is a close call between DeLonghi Portable Air Conditioner and the SereneLife Compact Free-standing Portable Air Conditioner. Still, ultimately, the DeLonghi product came out on top of my list. I decided on an excellent cooling impact and a relatively large-sized water tank. It is energy-saving and quiet while operating, with automatic features like the timer and remote that enhance the user experience – it sure made mine better and more comfortable! I also appreciate its oscillatory design because it covers a wide area, while the timer and remote controls are also present in this air cooler for more comfortable use.
