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 top to a floor stand with 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.

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.

    Just bought a Duux and am very satisfied. after buying 5/ 6 fans at the hardware store over the past few years this is what I was looking for. Really whisper quiet and nice design. well done Duux. Going to recommend it to friends. Gr. Joost

    Well, what can I say...saw these advertised on a TV selling program, they said they were amazing (as they would of course, they want to flog them) so I looked them up. When I started to read up on them, and saw how many places sold them, I dug a little deeper into who makes them. After a little while, I was convinced enough to give them a chance. They arrived super quick, took no time to put together, and it wasn't long before we were able to see if they were as good as they were claimed to be...they are, they've been on 24/7 since they arrived. They sip electricity, they are so quiet the cats don't mind them being on, you barely hear them, a massive plus is they're completely modular, so if a part breaks, you can just replace that part, and not the whole thing. The app control works brilliantly, the remote is very good...the digital assistant integration is very hit, and miss though, which is a shame. You can purchase a battery for these if you want to run them unplugged. Shame Very only stock the white version, and not the black, and silver versions though, but it is what it is. To sum up, they do what they claim they can, and are well worth it...they've performed incredibly well in the recent heat.

    I've had it for a year now and I can't live without it. Always a cool breeze, for a wonderful sleep. You hardly hear it. Sometimes I even forget to turn it off so quietly. Then you can turn it off remotely.
    Sometimes I put it outside and read a book in the sun without sweating. I am now going to buy my second one, because my children also want to sleep so quiet and cool. This fan really comes highly recommended!

    I received these yesterday. Delivery went smoothly. Assembling and pairing via the app was easy. Operation can be done via the app and the included remote control. Nice that you can use this model via both 2.4Ghz and 5Ghz wifi. It is super quiet, a nice breeze. Really highly recommended on hot days.

    I bought this fan some time ago through Bol.com. I am extremely happy with it, nice and cool, several modes and quiet. Small downside, I received version 1, which only works on 2.4Ghz. I now have to use 2 apps for my Duux devices. App is not really necessary as the remote works fine. But it works a little easier then, everything in 1 app.

    Acheté il y a 2 ans, je n'ai toujours que des compliment à faire sur mon ventilateur Duux. Toutes les choses promises sont au rendez-vous : silence, la fonction que j'appelle "brise en foret" qui envoie un flux plus naturel, moins continu, et la double rotation verticale et horizontale.
    Cette année j'ai fait l'aquisition de autres Duux pour apporté un peu de fraicheur à ma mère et ma belle-mère, qui ne voulais pas entendre parler de climatisation et encore moins de ventilateur (beaucoup trop bruyant disaient-elles) Elle apres un essaie avec le mien d'une semaine chacune, elle l'on adopté sans aucun problème.
    Donc les 5 étoile sont même partager par elles aussi 🙂

    Impossible de se connecter avec le wifi.
    Pas de pile dans la télécommande, au prix du ventilateur c est quand même une honte.
    Aucune explication clair sur le manuel en cas de problème (connexion Wi-Fi)
    Je regrette mon achat

    I would like to share my excitement about the Duux Whisper Flex Smart fan I recently purchased. Let me start by saying that this has been an absolutely great buy! If you are looking for a fan that will meet all your needs, look no further because this is it!

    First of all, the design of the Whisper Flex Smart is very modern and stylish. It fits perfectly into my interior and even adds a touch of elegance to the room. The slim and compact shape also makes it very easy to place it anywhere I need cooling.

    In terms of performance, I am very impressed. Despite its modest size, this fan blows powerful, refreshing air and quickly cools the entire room. I especially appreciate the different speed settings, which allow me to adjust the airflow to my liking. Whether I want a light breeze or more powerful cooling, the Whisper Flex Smart can do it all.

    The "Smart" feature of this fan is a real game-changer! Using the Duux app on my smartphone, I can control the fan remotely. Moreover, it integrates seamlessly with my smart assistants, so I can even control it with my voice.

    Another great feature to highlight is the fact that the Whisper Flex Smart is whisper quiet, as the name implies. I can enjoy a cool breeze at night without being disturbed by annoying noise. It is truly a relief to have a fan that is so quiet and yet so powerful.

    The quality of the materials used in the Whisper Flex Smart is also excellent. I feel that this fan is made to last, making it a long-lasting investment.

    In short, I cannot stress enough how satisfied I am with my purchase of the Duux Whisper Flex Smart fan. It has exceeded all my expectations and I would highly recommend it to anyone looking for a high-quality, stylish and smart fan. With this fan in my home, I can get through the summer much more comfortably. Duux has really outdone itself with this model!

    Great fan.
    We have the model with battery and a plug. It can only run on the battery and when it runs out of power you can run the fan on power and at the same time the battery is also recharged.
    We use the fan against flies in the bedroom, air circulation in the room/kitchen in winter and for air circulation in summer. We dare to say: an all-rounder.
    Is this model still for sale?

    Purchased them since about two months, app was tricky for a while. But by splitting the wifi into 2.4 and 5 after that easy to adjust. Fan is quiet and with the functions easy to control, especially if you want it not running all day. Highly recommended!

    I bought two Whisper fans 2 summers ago.

    When I got them out of the attic a month ago, one's power adapter stopped working and now the other's battery won't charge and beeps terribly when plugged in.
    When I pay €230 for 1 fan with dock&battery I expect it to work longer than a few months....

    In the meantime I bought 2 new fans that were a lot cheaper and were more powerful.

    No more Duux products for me!

    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.

  29. Petrareviewt (via Bol.com)

    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.

  30. GravityZ (via Bol.com)

    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.

    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.
