The ultimate fan completely smart and wireless

Wireless wonder
Whisper Flex: the first design fan with the option to make it completely wireless. Thanks to the free smartphone app and optional battery, you can use this fan anywhere and take it with you; for example, to your bedroom or that spot in your garden where you like to read a book. It is height-adjustable and transforms effortlessly from a table to a floor model thanks to its horizontal and vertical swing. And the best part? It is whisper-quiet, so you can concentrate on that one book or sleep in peace.

Please note that this product comes without a dock & battery pack. These can be purchased separately here.

Less is more
The fresh, modern design of the Whisper Flex sets new standards. With its attractive, sleek looks and ultra-modern LCD display controls, it feels at home in any environment. It is available in black, white, greige and sage.

Perfect sleep
In night mode, the display switches off completely after 10 seconds to ensure a good night's sleep. The display can be reactivated by pressing the operating button. At the lowest speed the fan produces only 13 dBa and thanks to the double blade design the cutting wind noise is reduced.

Uncompromising performance
The Whisper Flex is an all-rounder. It has 26 settings, is energy-efficient and has a powerful motor with double fan blades. Moreover, thanks to the horizontal and vertical swing, the wind blows in all directions. And all that with minimal noise production.

Every conceivable setting
Choose from 26 adjustable speeds and multiple modes. In natural wind mode, wind speeds alternate to simulate real wind. The night mode ensures a good night's sleep thanks to minimal noise production and the automatically dimmed screen.

Full control
The Whisper Flex has plenty of intuitive control options, such as the aluminium dial and the high-resolution LCD screen in the middle of the interface. Oh yes, you don't need to get up: you simply control the Whisper Flex with the Duux smartphone app or remote control, which magnetically clicks into place at the back of the device.

The extension piece transforms the Whisper Flex from a table model (51 cm) into a floor model (88 cm). The optional dock and battery turn Whisper Flex into a truly wireless fan. The battery lasts up to 18 hours, depending on the settings.

This is not recommended due to the stability of the fan. In addition to the table model, the Whisper Flex Smart can be raised with the supplied extension piece.

If your Whisper Flex Smart makes a scuffing sound, the fan blade is probably mounted the wrong way round. The pins of the shaft should fit into the notches of the fan blade.

    Fantastic fan. Incredibly quiet, simple controls, cool app that works very easily and the design is really well thought out. The Apple among fans.

    The first year I was very happy with the "silent" Duux.
    When I let it rotate from left to right, it makes ticking noises, which is very annoying, especially at night. It cannot be wear and tear, because the use has been minimal.
    So the product in no way meets my expectations. Too bad!!!

    Super quiet cools perfectly
    Just such a shame that for that price it doesn't even come with a battery for the remote control? Therefore 4 stars instead of 5.

    Ridiculous how quickly the adapter of the Duux whisper (white) gives up. Try to order a new one but it does not work on the duux page!

    Really quiet, at low speeds no sound at all and even at low speeds a lot of air is delivered, I always run it at low speeds, all in all a fantastic product.

    Great fan, whisper quiet. Variable speed is top.
    I would like to have some suggestions: lighting (backlite) in the remote and swivel angle adjustment via app.

    Blows quietly and harder than expected. Really a super thing. The remote control is also really handy. No idea if the app is good, can't find it here. Overall it's worth the money. Double swing function, and 26 wind speeds. Ideal to have next to your bed because of its silent motor.

    Best fan ever! I have a Dyson fan of 400 euros but so happy I bought this. The natural mode where it simulates wind like outside is amazing. In that mode it will automatically adjust the speed to simulate the wind outside. In this mode you can still set the max speed which is great. Swiveling horizontal and vertical is completely without noise. It works very well but I don't even use it. I have positioned it in the middle at the foot end of the bed and both me and my girlfriend feel the air. With natural mode on the fan and ocean sounds on Google home it's like we are lying on the beach! I don't understand people saying it's too expensive. It's 99 euros or 149 euros to have it with wifi so you can control with an app and Google home. The fan is super quiet. If I set it to a position that matches the air strength of the Dyson this Duux is very quiet while the Dyson sound like a jet taking off. A conventional fan chops the air which causes that vibrating sounds so typical of those fans. This fan has a double blade design which fixes this vibrating for a large part. So happy with this fan and for a very fair price considering the functionality, innovation and design. Well done Duux, hope you do well as everyone should hear about your Whisper fans!

    Bought it because it could be operated with google home. The strange thing is you can only turn it on but not off! And the only thing you can do, besides turning it on, is raise or lower the level by one step at a time. Since the fan has 26 levels it is impossible to turn it up or down with google home. So you can't say 'turn the fan on 20'.

    Strange and I hope that duux will be able to adjust this. Otherwise, this fan is too expensive for what you get for it.

    Very happy with this purchase. I had looked carefully at the reviews of different fans beforehand. I chose this one and a tower fan for the children's room. Unlike the others, I am very satisfied with this one. It is very powerful, has many functions, the head can really rotate in many positions and the program for this is excellent. The controls are logical, even on the stand itself. Whisper quiet and a big plus that makes it stand out from many others: It can be dismantled for easy storage during the winter.

    Just got my 2nd was already so satisfied with the first one I bought last year! Unfortunately the battery pack is out of stock because I would have liked to have it like my first one. Mega recommendable, quiet and good cooling, many positions and ideal for at night! Can't stand noise when I want to sleep. Costs whatever but is definitely worth it!

    Very nice fan from Duux. This is the first fan (and I have tried many) that is really quiet. Ideal for the bedroom. It has settings from 1-26 but is still pretty quiet on setting 4 but produces enough wind for a cool breeze. The fan can also move horizontally, vertically or simultaneously. This also happens very quietly but for me it gives just a bit too much noise so I don't use that option in the bedroom. I have 2 flex fans for the bedroom and a Flex smart (with wifi control and app) for the living room. With 1 of the fans I found that the fan blade was not quite centered which made it vibrate a bit. Just called Duux support and they have solved this perfectly. Operation with the remote control is very simple. You can also operate the fan on the fan itself. This is also easy, although you have to know how it works. All in all, I am very happy with this fan, both the Flex and the Flex smart.

    Fine fan, easy to use and all the way with the support of google home, also the battery pack for this fan is a solution, so you can place the fan anywhere. In short, value for money

    Very clear packaging, making it very easy to assemble.
    He is indeed whispering quietly, so quiet that at first you looked to see if he was on.
    Enough positions and strengths!

    He would have liked me a little higher in the floor position.

    Fast shipping.

    Because it was getting a bit warm in the attic, I decided to buy a fan. Looking for a fan that doesn't make a lot of noise (better for sleeping), stands firmly, has a display that can be switched off at night, can move both horizontally and vertically and can be controlled remotely (with a remote control but I much prefer using the app), you quickly come to this Duux . Not the cheapest, but more than worth it in terms of quality. Don't hesitate, just buy it!

    A super quiet and fine fan. Best purchase of the year so far. I have a very hot room (read 30+ degrees when it's hot outside) and I can't sleep because of the noise of normal fans. This one blows hard and is quiet. The fan can also blow in all directions, so that the air flow in the room is maintained. There is also a function to get a natural breeze, which is super nice too (close your eyes and it's just like lying on the beach). It's also super nice that you can control the fan via both a remote control and an app on your phone.
