You can select “Auto” mode for carefree climate control or you can opt for the simple 3-speed “Fan” function to improve air circulation.

Ideal for home or office, this portable AC unit can be used in a static position or oscillating for maximum cooling. Additionally, the device comes with a wireless remote control. Thus, you can adjust the settings without having to get up from your seat. The remote has a useful LED display, which is quite handy if the heat wakes you up during the night.

Overall, this portable AC unit is a fantastic option for muggy summer days or chilly winter evenings, but it does have a couple of drawbacks. It’s rather noisy, which, if you’re a light sleeper, may make it difficult to use overnight. Moreover, while the omnidirectional casters certainly help, this model is a bit heavy. Hence, elderly or frail individuals may struggle to move it around the home.

7. De Longhi PAC EX100 Pinguino

de-longhi-pac-ex100-pinguinoThe De’Longhi EX100 Pinguino Silent Air Conditioner is a cutting edge portable air conditioner that uses ‘Real Feel technology’ to ensure your room reaches optimal comfort conditions using a combination of dehumidifying and cooling. You can leave it to do its work and once it’s reached perfect conditions it will maintain them.

This model is a good choice for you if you’re looking for a hassle-free, easy to use installation that can do the work on its own to optimise your comfort. As you can leave the unit to maintain the ideal conditions, it doesn’t have a timer function. Although, it is good to note that it is rated A++ for energy efficiency, which makes it the only portable air conditioner in our selection to achieve this standard.

This stylish looking unit has an integrated remote holder so you don’t have to worry about losing it down the back of the sofa. It also includes an integral bio-silver air filter to remove allergens and pollutants, making it a great choice if you’re an allergy sufferer, just be sure to seal your window too. While this product is marketed as silent, it is still quite noisy which is to be expected with a portable AC.

This is a great purchase that is easy to use, looks great in any room and will purify your air. But a word of warning – it will, however, still be pretty noisy to run even if it is said to be one of the quieter options on our list. Note that if you purchase it, you may need to buy an additional exhaust hose as the included hose is rather short and severely limits where you can place the unit.


  • Top rated for energy efficiency – A++
  • Integral bio-silver air filter to remove pollutants and allergens
  • Stylish looking
  • Integrated remote
  • Real feel technology – combines dehumidifier with cooling to create optimal comfortable conditions

8. Pro Breeze 5L Cooler (Best Value)

pro-breeze-5lIf you’re looking for a simple, portable air conditioner to keep you comfortable in hot weather, then this model by Pro Breeze could be your perfect match.

Offering four different modes, this air conditioner uses advanced technology to maximise cooling efficiency, while still being economical to run. Warm air is passed over a honeycomb waterfall system of ice-cold water, before being blown back out into the room. By eliminating the need for refrigerants, this unit provides a cheaper and more environment-friendly alternative to traditional AC units.

Settings are easy to monitor and adjust, thanks to the clear LED display and wireless remote control. If you’d prefer to tweak the settings once and leave the unit to run, this is easy to achieve by using the 7-hour timer. A special ‘night-time mode’ claims to reduce noise levels while you sleep, but some users have complained that this is still too loud.

This unit comes complete with two reusable cooling packs and a large 5L water tank. Although you’re unlikely to change the water frequently, it’s worth noting that the tank can be a little awkward to remove and replace when the time comes. Also, the instructions are quite poor, so you may struggle to get the hang of it at first.

Nevertheless, this portable AC unit makes a highly-effective, eco-friendly, and economical solution to uncomfortable temperatures at home and in the office.


  • Choice of 4 cooling modes
  • Clear LED display
  • Wireless remote control
  • 7-hour timer
  • Comes with 2 reusable cooling packs

While it comes with castor wheels for easy movement from one room to another, it is pretty heavy, so you may find it a bit tricky to carry up and down the stairs. Furthermore, if you’re using it with a window seal, bear in mind that the exhaust hose is very short, so unless you attach an extension, you will need a window near the floor.


  • 9,400 BTU/h cooling capacity
  • Dehumidifier and three-speed fan functions
  • 24-hour electronic timer and thermostat
  • LED control panel
  • Remote control


  • Can be quite noisy when used overnight

How Do Portable Air Conditioners Work?

Portable ACs are great appliances to have especially during really hot days. It works in the same basic manner as installed air conditioners, using refrigeration gases to cool warm air and eject heat.

When manually switched on, or when the ambient temperature reaches the thermostats’ trigger point, the portable air conditioner will begin to suck the air in through an air inlet grille, usually through a filter.

Once the warm air is inside, it is circulated around a refrigerated coil. This cools the air by absorbing the heat present, turning it into a vapour. This heat is then forced through a compressor and condenser, which turns the vapour back into heat and water.

The heat is blown outside, while the water is usually collected in a drip tray. This cycle continues until the room temperature has reached a comfortable level.

Benefits of Using a Portable Air Conditioner

In this section, we take a look a some of the key benefits of using a portable AC in your home or office.

1. Saves Space

a-mobile-air-cooler-in-the-living-roomA cheap portable air conditioner offers a great solution if you live in a small flat, or spend all day in a cramped office. Because they are so compact and portable, these air conditioners can easily fit into those rooms that cannot accommodate big bulky appliances.

This is also especially true if you have limited windows which you wouldn’t want to give up in exchange for an installed AC system. Portable air conditioners allow you to retain the vast majority of your window space, whilst still efficiently cooling the area.

2. Convenient

One of the greatest things about portable appliances is their convenience. You can use them wherever you need. air conditioners are no different as they are easy to use in the office during a particularly hot spell and then take them home with you at the end of the day.

Portable air conditioners can also be used to keep you comfortable when you go away on holiday. Due to their small size and manoeuvrability, portable air conditioners make a great choice for use in campervans, tents and holiday apartments. Many models also have wheeled bases, so you can easily push them around to wherever some cooling air is needed.

3. No Installation

In contrast to central AC systems, portable air conditioners don’t require any installation to get them set up. All you need to do is plug them in, connect the exhaust to a window and you’re done! Thus saving you lots of time and unwanted hassle on a hot day.

4. Multifunctional

Many portable air conditioners will double as dehumidifiers, enabling you to cool the air and reduce relative moisture. High-humidity can feel uncomfortably oppressive and is particularly unpleasant if you suffer from asthma, hay fever and other allergies.

In this regard, portable air conditioners act as two appliances in one, saving you both money and space. Some of the best home air conditioners offer heating and fan capabilities too, so they can be used all year round.


All of the above portable air conditioners would make great choices to help cool hot air on a stuffy day. But if we had to pick our overall favourite, it would be the Air Conditioning Centre KYR-25CO/AG.

Offering a powerful 9,000 BTU (British thermal units) cooling capacity output, this air conditioning unit is capable of easily cooling small to medium-sized rooms of up to 20 square meters. Although it is a little heavy at 27kg, you can effortlessly move it from one room to another as required, thanks to its built-in castors.

If humidity is bothering you, the KYR-25CO/AG can deal with it. An internal condensation pump sucks the moisture out of the air, leaving you feeling cool and comfortable.

As if that wasn’t enough, you won’t need to get up from your sofa or workstation to adjust the settings. This portable air cooler comes complete with a handy remote control so you can easily operate it from wherever you are in the room.

After taking all this into consideration, we’re sure you’ll agree that the Air Conditioning Centre KYR-25CO/AG is currently the best portable air conditioner in the UK.
