As the UK heatwave continues, many are finding that traditional fans just don't cut it. While they circulate air, they don't actually lower the temperature, leaving rooms feeling stuffy on 30C days. Air coolers offer a more effective solution, using water to cool the air without the need for installation or expensive refrigerants. They are cheaper to buy and run than portable air conditioners, making them an attractive option for many households.
Reviews from the past decade of testing cooling kits have highlighted several top performers. The Dreo Turbocool Misting Fan 516S emerged as the best air cooler, impressing with airflow speeds of up to 5m/s in turbo mode. It reduced room temperature by around 2C in an hour, with noise levels topping out at 40dB. The unit costs about 1p per hour to run and features a 1.3l water tank that lasts up to 12 hours.
For those prioritising energy efficiency, the Swan Nordic two-in-one air cooler is a standout. At just 27W on full power, it costs less than 1p per hour to run, making it the most energy-efficient option tested. It offers 24 speed settings and a slim, premium design that fits neatly into any room.
Other recommended models include the Princess air cooler with three airflow modes and smart app control, and the Daewoo air cooler which doubles as a humidifier to ease hay fever symptoms. Both are from trusted brands and offer remote or smartphone control.
The Dreo Turbocool also impressed with its smart features, including app connectivity for real-time monitoring of temperature and humidity, plus a built-in light that indicates humidity levels. Its 150-degree horizontal oscillation and 30-degree vertical tilt ensure effective air distribution. While the unit may feel slightly overcomplicated at first due to multiple settings, it is one of the most versatile compact coolers available.
