Both an air conditioner and dehumidifier, it cools and dries rooms quickly despite using an eco-friendly gas, which has no greenhouse emissions.

Top review: "Fantastic!!! So quiet compared to other models and cools the room so quickly!!!! Love it."

Dorman & Walsh 3 in 1 air conditioning unit, £389.99, Amazon

SHOP NOW

With an adjustable fan speed cooling the air to 15.5 degrees at its coldest setting, and a sleep mode which makes the unit gradually reduce its output as the temperature cools during the night, this clever air conditioner has all of the features you could want for your home. It’s also very lightweight, making it easy to move from room to room.

Top review: "The air con unit was super easy to set up & is an absolute lifesaver in this tropical weather. It’s really quiet so no problem getting to sleep with it running. (I have it set up in my bedroom). I would highly recommend this Dorman & Walsh air con unit as the room was so lovely & cool in such a short period of time that I had a little nap during the day after nights of disrupted sleep. 5 Stars!!!"

MeacoCool MC Series Portable air conditioner, £499.99, Amazon

SHOP NOW

At just 20.5kgs and 70cm tall, this air conditioner is small but powerful enough to quickly cool your bedroom or home office without taking up much room. It features a digital display, remote control, sleep mode and uses an eco-friendly R290 refrigerant.

Top review: "Bought this for a warm lounge in 30 degrees. Chose this for price, energy efficiency and the refrigeration gas it uses is more environmentally friendly. Easy to set up, didn't take long to get going. Vented hose out of patio door and even without using the window seal it cooled the room quickly and efficiently. It is noisy similar to others on the market so probably couldn't use it to sleep. But great for keeping us cool in the day where fans are useless."

Princess Mobile air conditioner, £275, Amazon

SHOP NOW

This air con unit has three settings; cooling, dehumidifier and fan, all with adjustable fan speeds, so you’ll use it far more often than just the hottest days of the year. The castor wheels mean it’s easy to move to wherever it’s most useful, and it includes timer and scheduling features. Plus, right now it has 25% off.

Top review: "Really pleased with this purchase. Love the fact I can control this from my phone so I can turn it on before I go into my office which can get hot and stuffy. Quite a nice design and added bonus to add ice packs to the water tank. I considered buying an air con unit but didn’t want to pay £250+ so this is a great alternative for anyone looking for a more affordable solution to keep cool."

BLACK+DECKER Portable 3-in-1 air conditioner, £428.12, Amazon

SHOP NOW

Powerful, with an LED digital display and energy-saving sleep mode, this bestselling air conditioner is one of Amazon’s most highly rated. It comes with a window kit adapter and 1.5 m exhaust pipe for easy installation.

Top review: "Bought this for our bedroom, as a night shift worker sleeping during the day in summer heat is a real issue. Fortunately, this great value aircon unit does the job perfectly. It's a little noisy but in my experience mobile units tend to be... Managed to cool the room down sufficiently quickly, has a useful remote control that sits in a pocket on top of the unit when not in use. Great value portable unit, highly recommend."

KGOGO portable air conditioner, £279.98, Amazon

SHOP NOW

Thanks to its advanced air compressor, this unit comes in a compact size but is still super efficient. It has cooling, fan and dehumidifying functions, plus multiple reviews say they love that it's fully evaporative, getting rid of water through the exhaust vent rather than having to empty a water reservoir.

Top review: "I've used this type of AC before at my old office, so knew what to expect, only this one had a nice surprise which was no water tank! Usually ACs have a tank to accumulate water and need emptying every few hours, but this one evaporates the condensation out with the hot air, which just seems like common sense! As far as freestanding units go, this one is smaller than most, and it's not too loud when it's running either. Once the compressor kicks in, the air it sends out the front is freezing. Does what it says on the tin."

Beldray Ice Cube Plus+, £19.99, Amazon

SHOP NOW

For something smaller and very affordable, Beldray's Ice Cube Plus is ideal. Using two removable water tanks, the lightweight machine cools and dehumidifies the air around you. It has an adjustable three-speed fan so you can choose from a chill breeze or a cold blast depending on the heat. With USB capabilities, it's perfect for a work desk or personal office.

Top review: "I really wasn’t expecting much from this little air cooler so was pleasantly surprised how good this was. Easy to use and there was a lovely cooling air flow, perfect for a bedroom, or just sitting on your desk or coffee table. Just keep a eye on when it needs refilling, around 4/5 hours after plugging in. Would recommend."
