What Is a Personal Air Conditioner?

Quite simply, they are a condensed version of the big, heavy-duty machines. It’s worth mentioning right away that when talking about personal devices we mean personal evaporative coolers, as air conditioners (even though referred to as such, sometimes) don’t get small and light enough to operate in your personal space only. So if you encounter the term “personal air conditioner,” nine out of ten times you’ll find a device based on evaporation, not refrigeration.

Air Conditioners vs. Air Coolers

Both thermal appliances are devices that keep us cool by removing the warm air and lowering the temperature of the air around us. However, they are not quite the same, as they use different methods to decrease the temperature of the room. For example,

  • An air cooler does not use a chemical coolant; instead, it removes heat from the air via water-absorbent pads. They usually feature a removable water tank, and you will need to refill this with water at regular intervals.
  • An air conditioner uses chemical refrigerants to alter the temperature of a space. They can be more effective and may be better suited to cooling sizable spaces; however, they are not as budget-friendly, portable, and versatile as air coolers, and they have higher energy consumption.

Why Choose a Personal Evaporative Air Cooler?

Whilst more-permanent machines can be more efficient, especially for larger spaces, they are not always practical and can have high energy consumption. The ability to move a personal evaporative air cooler as needed means they are a great choice for any situation where versatility is essential.

They are also an excellent option for anyone who cannot make any permanent changes to their property, such as renters, with personal units requiring little to no installation. Plus, advancements in technology have meant they can be just as effective for cooling your immediate personal space.

How Do Personal Air Conditioners Work?

A mini evaporative cooler has all the parts an ordinary portable swamp cooler would have, only these parts are compact. It has a small water container, a fan, and a filter that will absorb water and aid the evaporation process with its surface. As the fan works to blow air through these pads, the surrounding area is cooled.

How does an evaporative cooler work?

Mini air conditioners connect to a power supply via a power adapter. However, a lot of models have a USB cord so you can use it with any device that allows that kind of connectivity: computer, power bank, AC plug, etc.

Features That Benefit Your Personal Space

Compact air coolers have some nifty features that set them apart from their big, bulky counterparts. Here’s why you should choose a personal air conditioner.



When you are choosing a swamp cooler, determining the size of your room and the amount of space you want cooled is essential. Besides, if you’re going to use a micro air conditioner in different rooms of the house, it might not work in all of them equally well due to the different square footage.

On the other hand, a mini air conditioner will cool down your personal space regardless of how big or small the rest of the room is.

One of the best benefits of portable air coolers is the ability to move them. However, the term “portable” is often used with abandon. They are often heavy and difficult to maneuver, and very few models are easily transportable, with some weighing up to 50 kg.

The best personal air conditioners weigh about two to three pounds — light enough to carry, but heavy enough that you won’t be able to just knock it off a surface.

3-in-1 Functionality

As with any swamp cooler, a personal air cooler has a 3-in-1 functionality as a cooler, a humidifier, and a purifier. This means that it also makes the hot, dry air around you much fresher. As well as removing dust particles and making the air easier to breathe, the humidifying aspect of this unit can help prevent mold spores from spreading in your home.

Low Energy Consumption

One benefit of using a mini air conditioner, in comparison with a fixed option or even an ordinary portable one, has to be the energy efficiency — personal air coolers consume much less energy.

Similar to other electrical appliances, air coolers are given an energy rating, with A being the most efficient and G the least. Air coolers are measured by British Thermal Units (BTU), which refers to the amount of heat the appliance is able to extract from the room. For compact air coolers, it’s up to 1500 BTUs per hour.
