Portable and personal air conditioners, or portable air coolers, are extremely useful in the summers because of their ease of use and cost-effectiveness. They can be used in places that have space limitations or building restrictions. Furthermore, these personal air coolers are portable, easier to maintain, priced cheaper, and eco-friendly by consuming less power.

Unlike standard central air or window ACs, portable air coolers, as the name suggests, do not require a permanent installation or yearly maintenance. They can easily be moved from one area to the next because they are lightweight compared to the other cooling options.

These personal air coolers can be used anywhere, be it your workplace or your bedroom. Its cost is also much less than conventional ACs, which means that they’re not as heavy on your pockets as the other options.

How do Portable Air Conditioners work?

Modern technology has made it easier for us to use complex air cooling technologies in smaller personal use units. The personal air coolers follow a rather common method; the cold expulsion of air is created when warm air passes through a water curtain. These personal air coolers are built for smaller areas such as bedrooms and offices.

More advanced technologies are available in the standard window or central air conditioners, which render them more effective, although more expensive and not as cost-efficient. Other conventional models have as much as 12,000 BTUs, making them capable of spreading cooler temperatures over a greater area. However, they require venting hoses, which means that they need an outlet to send out the warm air and moisture. While some of these models require a way to expel warm air, others require two hoses to do that. They also tend to be noisy, use relatively more power, and since they withdraw humidity from the room, they tend to make the room drier. Therefore, even though they do not require a conventional set-up, they require a more firm setting than the options presented below.

The portable personal air coolers mentioned below, on the other hand, increase the moisture in the air, making it more pleasant. They simply reduce the room temperature without creating any dryness in the room. Heat extraction is common to both, but while the former uses freon refrigerant or noisy compressors, the latter doesn’t.

The technology which is being used by the units listed below is a basic process. First, the unit intakes hot and dry air from one side of its body. Then, after entering the unit’s body, the warm, dry air is made to pass through a water curtain connected to a hydration chamber (in some cases, ice trays), which is cool and wet. This causes the water in the curtain to evaporate. To evaporate, water needs to withdraw heat from the air; thus, it gives the previously hot and dry air a lot of moisture and coolness. This cool air is then pushed out through the front of the unit using a fan, which helps lower the temperature of your room.

Advantages of Using Portable Personal Air Coolers

Portable personal air coolers, as mentioned, are a boon to modern life. Here are some advantages it has over the other larger standard cooling systems.


Using portable personal air coolers, you can save hundreds, if not thousands, of dollars a year. A whole-home HVAC (Heating, Ventilation, and Air Conditioning) takes up a huge sum of money. Not only are portable personal air coolers cheaper, but they can also save energy because it will only incur costs from the room in which it is being used. Since it is small and energy-efficient, portable ACs run on a battery charged using a USB port. As a result, its energy consumption is usually compared to that of a smartphone or tablet.

Add Humidity

Unlike other forms of air conditioning, portable personal air coolers use a water-curtain mechanism that allows them to add humidity to the air rather than removing it. Many people face skin and nasal passage problems because of the dryness of the atmosphere around them. Therefore, you can benefit from having a portable AC. All the ACs mentioned in this list increase the humidity of the room while lowering its temperature.

No Installation Required

Because of the handiness of portable ACs, they do not need to be installed like other forms of ACs. Therefore, you save installation costs, and you can quite literally take it anywhere you want because it does not require a separate expulsion of hot air and moisture. You don’t have to install plumbing or risk ruining your window. Just pour water and let the AC cool your room.

Air Filtration

Many portable personal air coolers offer the feature of air filtration, meaning that they have additional filters through which they remove allergens, dust, pollen, bacteria, viruses, toxins, and other compounds. The filters can vary from each other. Therefore their efficacy depends on which kind of filter a particular portable air cooler is using. For example, you can have a UV light filtration system or a physical filter instead of the UV light filters. It is the sign of a good unit to filter the air more effectively than others.

Alter the Temperature

While most portable air coolers do have an option of having a thermostat, others do not. Depending on the kind of portable AC you have, it can offer you about 3 to 5 fan speeds for cooling modes which will help you maintain the room temperature. Although they don’t offer you the feature of choosing exactly the temperature you want the air to be, you can still navigate the temperatures through approximation in degrees.

No need to plug in

Most, if not all, of the best portable air coolers, have rechargeable batteries that run them, and these can be charged via a micro-USB. Thus, you don’t need to worry about how long the cord is. It will reach your table or your bedside. You can simply just keep moving it around once fully charged.


While we already know that these devices are cost-effective, with a low maintenance cost, it should also be noted that they cost considerably less to buy. While you get ordinary air conditioners in the range of $5000 +, you get the best portable ACs for around $90. You save thousands of dollars. Not to mention, you also save on the installation and utility costs as mentioned above.

Easy to use

These portable ACs are extremely easy to use. They can be used by anyone at all. You do not need any specialized or technical knowledge whatsoever. You only need to know how to fill the tank and add ice cubes and how to charge it, to know how to make a portable AC work right out of the box.

Easy to Move Around

While conventional ACs require to be fixed into one spot, need a venting outlet, and whatnot, these portable ACs don’t need anything at all. Therefore you can move them around the house with no hassle at all. Even if you own a relatively larger model of these units, they usually come with secure handles that can help you move them around your house.


Although they cannot replicate the temperatures of a whole-home HVAC system, they can still deliver an incredible performance, all at a surprisingly lower cost. They are very efficient at cooling your bedrooms, office, and other smaller areas.


One of the most attractive qualities of portable ACs is that some are very quiet. Some HVAC models tend to create a lot of noise. On the other hand, portable air coolers are extremely quiet and will aid your efforts to concentrate better and even help you sleep and relax more comfortably. Whether you’re facing sleeping problems because of noise or not concentrating at work due to noise, this is a perfect solution.
