Bladeless fans also have multiple other benefits that you might not have considered. Some fans have an ionisation filter, which sterilises the air as it passes through, as well as a HEPA filter that removes 99% of particulates out of the air, great for hayfever and people who might have breathing issues.

There are 3-speed settings, a timer that can be set for up to 8 hours, and a scheduling mode, letting you set up your fan to turn on, for example, half an hour before you get home. Until… one day I entered a metropolitan gallery for some “eye candy” of the cultural variety and was almost immediately surprised by a pleasant draft of air. I heard nothing and tried to locate the source. The Duux Whisper Flex Smart is a quiet, powerful and reasonably good-looking fan. It’s quite compact, with the advantage that you can convert it between floor-standing and desk modes. Its support for horizontal and vertical oscillation – including the ability to point almost vertically up – helps make it suitable for almost any application, from overnight bedroom use to cooling a big room on hot days. Both of these things are great, as they mean you’re getting a powerful but unobtrusive fan that can easily sit in the corner of your room and won’t overpower conversation or late-night TV watching!

First is the money-saving aspect. Smart fans can save you a lot of money, especially if you’re currently using air conditioning, but even if you’re not and relying on conventional fans. Oscillation range– There’s no fun if your smart fan only blows air out at one spot and you constantly have to mess around with it. This is a rare problem as most of the fans we’ve seen rotate automatically, cooling our entire room down. Today received the ordinary, non-smart Whisper White through Bol because it was unfortunately sold out here.

Choose from 26 adjustable speeds and multiple modes. In natural wind mode, wind speeds are alternated to simulate real wind. Night mode ensures a good night’s sleep thanks to minimal noise production and the automatically dimmed screen. Can you shout at it? Alexa and Google Assistant are great ways to control fans without reaching for your phone or the remote. Any good modern smart fan should work with the major voice assistants and, ideally, have more commands than just ‘on’ and ‘off’. The square tower design is sleek and modern, standing at just over a meter tall, with a silver body. The base is reasonably wide, which keeps it stable, but does take up a reasonable chunk of floor space.

The fan head requires simple assembly, with the front cover secured by a single screw. Inside the plastic cage there’s a unique blade design with distinct inner and outer zones. The outer ring contains nine stubby blades, whereas the inner circle has seven, so long that they almost overlap. Fan technology has changed a lot over the last ten years, with new designs and DC motors bringing in an era of quieter, more energy-efficient but still very powerful air-shifters. What hasn’t changed so much, however, is the way that fans are controlled and used. Buttons, switches and simple LED indicators are still very much the norm, and in an era when even light bulbs and heaters are working with apps and voice control, smart fans are few and far between. That same convenience can also make smart fans perfect for the elderly, or anyone who has lowered mobility due to illness or other factors, allowing them to control the temperature in their home without unnecessary strain.

The fan itself is a high power, with double rotor blades that pump out a lot of air while staying whisper quiet, from as low as 13db up to 50db. It can be adjusted in height so it can be placed on a desk or set up on a floor, and has vertical as well as horizontal tilt, giving you a huge variety of options when it comes to set up.We’ve looked at smart heaters in our previous post but now it’s time to take a look at some of the UK’s top cooling gadgets; fans you can control with your smartphone.

You'll also need to set up the fan's remote control. First, you need to slide out the battery compartment – you need to depress the button on the base to do this which isn’t mentioned in the instructions – and then slot in the battery aligning the positive polarity with the + symbol on the remote. The instructions don’t say which way up to put the battery in, so I hazarded a guess and slid the battery tray shut. We’re used to product names that bear little relation to reality, but the Whisper Flex Smart really is very quiet indeed. At its lowest speed setting, you can just about make it out in a quiet room. It wouldn’t disturb even the lightest sleeper. There’s considerably more noise once the speed setting enters double digits, but even flat-out it’s quieter than most other fans we’ve tested.
