Best Portable Air Conditioner Reviews – Top 9 Picks
The 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.
This 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.

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.
This 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.

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.

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.

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.

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.

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.
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 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.
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.
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.

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.
