I’m putting the Princess at number one because it gives the best bang for your buck and won’t take up much space when you’re not using it. However, this also means that the devices may not be able to achieve the desired results at high humidity. The large fan and the automatic swivel movement allow for optimal adaptation to weather and room conditions. The market has grown steadily as people look for more energy-efficient and cost-effective ways to keep cool during the summer”.

In 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. To clean the lower unit, turn off and unplug the unit and place it over a drain or something that can collect the water. This 5L Portable Air Cooler quickly and effectively cools rooms by using an industry-leading honeycomb waterfall cooling system that sends a soothing breeze cooled by ice-cold water vapour into your room.

It features a Three Speed Fan function from Low, Medium and High to deliver optimal cooling throughout. The Beldray 4 Litre Air Cooler doesn't require any permanent installation and is ready to use straight out of the box. Increasing the fan speed will result in faster consumption of the water or ice present in the tank, therefore the autonomy will decrease.

As an extra tip you can use water with a low level of limescale to prevent any sediment from causing encrustations over time.

The only drawback is the small water tank and equally small ice packs (chilling the water in air coolers makes them more effective).

I found it quiet enough to sleep with the air chiller next to the bed and it definitely reduced the night-time temperature by a degree or two. Don’t forget to get ready for the colder months too and check out our range of portable heaters to keep warm during winter. Unfortunately, it doesn’t move as much air as its 120W motor would suggest and is a little bit more unwieldy than the other tower models.
