Product Information

Air coolers are much cheaper to run* than portable air conditioners, averaging 2-4p compared to 20-40p per hour. They’re also much lighter, averaging around 6-7kg rather than 20-30kg, and require no complicated set-up – although it’s wise to leave a door or window open to avoid too much humidity building up in the room, reducing their effectiveness. The question is, can they compete when a heatwave strikes? AirConDirect’s Victor Stoica, another longstanding aircon expert, adds that they’re more environmentally friendly than refrigerant units, since they don’t use harmful chemicals. “Also, unlike air conditioners, they’re suitable for outdoor spaces like garages, workshops and patios,” he says. “They create spot cooling, dropping the air temperature by a few degrees.” Night Mode - Night mode lets you run the appliance at a lower speed and in a more energy efficient manner whilst you're sleeping, allowing you to enjoy the benefits of a cooler room. The associated HomeWizard app (for iOS or Android) allows you to give it voice commands using Siri or Google Assistant. I will never use those. Some will, but I can’t help feeling it would be cheaper without them. in-1 Features: Features 4 multi-purpose operating modes including air cooling, fan-only, natural, and night-time modes making it the perfect cooling solution for any home, bedroom or office.

The Princess – a Dutch brand – was the first air cooler I tried, in the middle of 2022’s heatwave when all the big-beast proper air conditioners were sold out. It was a bit of a revelation, reducing the temperature in my bedroom from an entirely unreasonable 23 degrees (at midnight!) to a more bearable 19. verifyErrors }}{{ message }}{{ /verifyErrors }}{{ The Princess has a ‘sleep’ setting, which means it comes on only intermittently to maintain a cool temperature. In theory, that means it’s silent most of the time. But on a very hot night the constant on-off may keep light sleepers awake. (See our guide to the best earplugs for help there.)Performance - In terms of performance, the unit has an air flow rate of 408 cubic metres per hour and a 1.1 litres per hour evaporative rate.

As of July 1 2023, the government’s Energy Price Guarantee caps the per unit costs at 30p per kiloWatt-hour for electricity, so that a 100W appliance costs roughly 3p per hour to run. We’ve used this as our guide to air cooler running costs, although they may be lower depending on your tariff. The Chillmax is one of the most searched-for air coolers, but that may have more to do with JML’s hard-sell TV advertising than its cooling ability – which, to be honest, is fairly minimal. At a mere 7.5 Watts, it’s less than one twentieth as powerful as the Symphony air cooler above and could more accurately be described as a vaporiser, projecting a cloud of somewhat cool mist for about a metre. Finally, air coolers can help to humidify the air in dry climates. This makes them a great choice for those who want to stay cool while also reducing their impact on the environment. Ultimately, the choice between an air cooler and an air conditioner will depend on your room size, budget, and setup needs. * Air cooler running costsIn fact, that is probably the ideal use, because it’s heavy enough to pose a problem getting up and down stairs if used at home, as well as taking up a lot of space and making a fairly industrial noise. You wouldn’t choose it for cooling your bedroom at night, but it’s the only one we reviewed that can stand a chance of cooling a 40 square-metre space. In terms of size, weight and cooling ability (they rate it at 12,000 BTU) electriQ’s 40-litre unit begins to approach portable air conditioners. It’s the one you’d want in a workshop or office at the height of the summer.
