Five of the best deals on fans and air conditioners
Our top pick: Honeywell TurboForce Power Fan | £23.49 (was £25) from Amazon - save 6%
Nearly 15,000 people have purchased this small but mighty fan. And you can feel the breeze from the fan up to seven metres away. With 90-degree oscillation, and three powerful speed settings, it is still quiet enough to sit by your desk or bedside table, and can also be mounted on the wall.
Pro Breeze® Oscillating 30-inch Tower Fan | £47.87 (was £79.99) from Amazon - save 40%
This elegant, space-saving 30" fan has 70-degree oscillation, three fan speeds and three wind modes (normal, natural and sleep) so you get the type of cooling you need whatever the situation. A wireless remote and timer means you can easily adjust it. And it's quiet, too. Plus running costs are low at approximately 1.6p per hour, and it has a 7.5 hour automatic on/off timer with flexible 30-minute increments. Another bonus? It has a built-in essential oil tray so you can have a refreshing scent circulated. (We recommend lavender for sleep).
BLACK+DECKER BXAC65001GB Air Cooler | £69.99 (was £79.99) from Amazon - save 13%
With low, medium or high speed settings and a fan-only and 90-degree oscillation mode, this portable air conditioner can offer you the kind of cooling you need for whatever room you're in. It works by evaporating cool water through its honeycomb filter (no need to ventilate out of the window). Simply fill the seven-litre tank with cold water and cooling packs (two are provided). It also has four wheels so it can easily be moved around.
Pro Breeze™ Professional Mini 6" Clip Fan | £13.97 (was £21.99) from Amazon - save 36%
This six-inch fan will clip onto your desk, a table or shelf - even your bedhead. It can rotate a full 360° degrees to change the air flow in any direction you want. The fan head also tilts so you can control the air flow, and it has two speed settings - a high power one for during the day, and a quieter, lower speed for when you're sleeping. Although it's mains powered, it costs less than half a pence per hour to run, and it comes with a one-year warranty.
Manwe 75° Oscillating Mobile Air Conditioner | £35.19 (was £43.99) from Amazon - save 20%
A four-in-one gem, this is an air-conditioner, desk fan, air humidifier and purifier. It has a spray function too, for a light spritz of water when you need an extra bit of cooling down. It has four wind modes, and wind direction can be moved up and down by 45°. It also has 75° oscillation so it circulates cool air widely. This little unit has a 600ml water tank - add cool water and ice cubes. It also has seven different light colours to help you feel relaxed and it's quiet enough not to disturb your sleep.
