This great-value air-cooler is an affordable and incredibly effective way to keep cool. It uses the power of evaporative cooling to chill the air, creating a natural, refreshing breeze. As evaporative cooling is a natural process, it uses barely any electricity – this model uses just 75W, so it’s cheap to run. Features: Evaporative cooling uses a tank of water which, as it evaporates, cools the air. You’ll need to refill this tank of water on occasion, but luckily, this model makes this a breeze. At the top of the unit is a spout which allows you to fill the tank without removing it. Just pour in your water, turn the air cooler on, and feel the chill! Air coolers work best when positioned near an open door or window. This means you’ll need to move them around to get the most out of them. That’s why this model is designed to be as lightweight as possible – it weighs just 5kg and is fitted with castors so you can wheel it around wherever it’s needed. If
