Best Portable Air Conditioner Reviews – Top 9 Picks

1. Air Conditioning Centre KYR-25CO/AG (Editor’s Choice)

air-conditioning-centre-kyr-25coagThe KYR-25CO/AG Portable is the best air conditioning unit in the UK that will help you stay cool in the summer months. This multifunctional air conditioner is simple to install and combats the heat in three different ways – so you can easily create a comfortable temperature indoors while the mercury rises outside.

Boasting an impressive 9000 BTU cooling capacity, this air conditioning unit is capable of cooling an area up to 20 square metres – perfect for the office or large rooms which get hot and stuffy during warmer periods. The powerful fan is also fully adjustable, so you can set it to high if you want to cool your room faster, before reducing the speed to limit noise levels if necessary.

A dehumidifier function extracts excess moisture from the atmosphere, minimising that unpleasant humid and ‘airless’ feeling commonly experienced in rooms with warm air. Additionally, the built-in air filtration system works to improve air quality as it cools. It’s no secret that air pollution and increased odours can become an issue in hot weather – so, if you’re sensitive to air quality, using this function will help to reduce any potential irritation of your airways.

As an added benefit, this air conditioner is fully Wi-Fi enabled. If you misplace the remote control, you can control it from your smartphone or smart home device, so you won’t need to get up from your seat to change the settings. That said, should you wish to move it to another room, the lightweight casters mean it is quick and easy to wheel it to a new location.

Overall, the KYR-25CO/AG is a fantastic portable air conditioner to help you survive the summer months, but there are a few downsides to be aware of. The compressor can be quite loud when set to low temperatures, which may be an issue if you plan to use this model overnight. The water tank also fills up quickly, so you should expect to empty it often if you’re using it on a daily basis. Lastly, it lacks a swinging option – this isn’t a big deal, but if you want to enjoy the breeze, you’ll need to be right in front of it.


  • Strong 9000 BTU cooling capacity
  • Effectively cools areas up to 20 metres square
  • Adjustable fan speed
  • Includes air filtration and dehumidifier functions
  • Easy to install
  • WIFI enabled controls


  • The compressor is quite loud
  • Water tank fills quickly
  • Lacks swinging mode

2. Igenix IG9901WIFI (Luxury Choice)

igenix-ig9901-wifiThis three-in-one portable AC unit from Igenix is Wi-Fi enabled and can be controlled via a smartphone app or with Amazon’s Alexa for voice commands. This makes it a good choice if you are looking for a new addition to your connected home or if you have any difficulty using conventional touch programming.

With a 9000 BTU cooling capacity output, it is suitable for rooms up to 20 metres squared. And thanks to its 24-hour timer, you can pre-set your unit so your room will be nice and cool when you arrive home. The dehumidifier can remove up to 27 litres of water per day, while the fan function has three-speed settings. Like many other portable AC units we have seen, this one is quite noisy to run, especially on maximum cooling levels. The short exhaust pipe means you’re limited to placing it right in front of your window which could prove difficult if they are high up. It does not come with a window kit, although it is recommended that you purchase one for added efficiency.

This portable air conditioner is a good choice if you have a smart, connected home, yet little else really distinguishes this particular unit. If you’re not particularly bothered about using the app or Alexa, then you’d probably be better off going with another of our top portable AC units.


  • Wi-Fi enabled – control via an app or Alexa voice commands
  • Multi-function: cooling, fan and dehumidifier
  • For rooms up to 20 metres squared
  • Easy to use control touch panel and remote

3. Igenix IG9901 (Best for Mid-Sized Rooms)

igenix-ig9901This stylish looking portable AC by Igenix can be also be used as a fan or dehumidifier. It uses advanced technology to self-evaporate the majority of the water accumulated during the cooling mode, reducing the number of times you have to empty it.

With a 9000 BTU cooling capacity output, it is suitable for cooling down an average sized room. It is easy to use featuring a touch control panel, a remote, sleep mode, and a 24-hour timer. You will also benefit from its three fan settings. It cools your room down quickly with rapid cold air distribution so that your room can reach a comfortable temperature faster. Unfortunately, like most portable AC units, it can be very noisy to use in cooling mode.

While we appreciate the good looks, energy efficiency and ease of use, there have been some faulty batches of this particular model. Also, the exhaust pipe that is included is quite short and there is no window seal or mount sold with it. All in all, this is a decent choice as long as you don’t get unlucky with a faulty model that will need returning.


  • Functions as an air conditioner, dehumidifier or fan
  • Three fan settings and a sleep mode
  • Can effectively cool small to medium-sized rooms
  • Comes with remote, touch control panel, and 24-hour timer

4. Igenix IG9902 (Best All-Season)

igenix-ig9902This portable AC by Igenix can heat, cool and dehumidify, making it a great option for all-season use. With a 9000 BTU cooling capacity, it is suitable for cooling medium-sized rooms or smaller. As a heater, it is a great complementary heat source. However, it is not powerful enough as a stand-alone heater over very cold periods. The display is easy to use and there is a remote included for convenience.

The 12-hour timer allows you to pre-cool your room, or set the unit to cool your room for a limited time. It also includes an anti-bacterial water tray to prevent the build-up of mould, as well as a carbon filter to dispel any unpleasant odours. It is fairly weighty, but it has castors to help make it easier for you to move it between rooms when needed.

Like many others, this portable AC unit is rather loud and you would probably not be able to use it overnight in your bedroom. Unfortunately, it can be tricky to fit the hose and it is rather short in length, limiting your placement options.

This model is one of the best cheap air conditioners for small offices or sitting rooms, as long as you don’t mind a little noise and you have additional heat sources for the cold period.


  • Multi-purpose air conditioner: cooler, dehumidifier, fan and heater
  • Suitable for small and medium-sized rooms
  • Active carbon filter to dispel unpleasant odours
  • Comes with remote and anti-bacterial water tray

pifco-p41008If you’re after the best air cooler in the UK, you’re probably looking for one which is multifunctional. The Manchester-based air conditioning manufacturer, Pifco, has created this portable AC unit that can be used three ways: as a fan, a dehumidifier or as an air conditioner. Although you will probably only use the air conditioning and fan functions during the warmer months of the year, the dehumidifier function can be useful all year round.

This portable aircon unit provides 7000 BTU cooling capacity which is sufficient enough to cool down a small sized room. Like the majority of portable air cooler units on the market, the compressor is quite noisy, which may be something to be aware of if you’re thinking of using it overnight in your bedroom. Thanks to its castors, it is easy to push from one room to another, although we don’t recommend moving it up and down stairs due to its 23kg weight.

It includes an exhaust pipe and window kit mount, as well as a basic remote. However, at only 1.5 meters long, you may need to order an additional longer hose in order to reach your window. Hose length aside though, it is easy to install and quick to get up and running. There is also a handy 24-hour timer, which can help you to save on energy costs.


  • 3-in-1: Dehumidifier, fan and air conditioning
  • Comes with remote and 24-timer
  • Window seal and an exhaust pipe is included

You can select “Auto” mode for carefree climate control or you can opt for the simple 3-speed “Fan” function to improve air circulation. There’s even a convenient 24-hour timer, so you can set the unit to switch on when desired.

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.

Boasting an Energy Class “A” rating, this model won’t rack up your household bills. The accompanying exhaust hose is expandable to fit standard-sized vertical or horizontal sliders. However, some users have complained the hose is shorter than they would like. It also comes with a window kit for universal compatibility.

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.


  • Offers 5 functions in 1 unit
  • 24-hour timer
  • Wireless remote with LED display
  • Oscillating mode
  • Energy Class “A” rated


  • Noisy

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.

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.

  • 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.
