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 Whisper Flex sets a new standard. With its beautiful, clean look and ultra-modern LCD control, it is at home in any environment. It is available in black and white.

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
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.

Our refurbished articles have been technically checked and found to be in order, but can contain very light user traces and/or damaged packaging. The full warranty applies.

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.

    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.

    It is whisper quiet.
    Easy to operate via the app.
    Beautiful design.
    Exactly as expected.
    I will buy a second one.

    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!

    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.

    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.

    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.

    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!

    When it works it is fine but the WiFi keeps dropping out and I have to reconnect it and take it to the router. Turning it on with the button is not so easier

    Since 2 weeks a Duux Whisper Flex in house (through the Bijenkorf)

    The bedroom cools down quickly and even on the highest setting you can hardly hear the unit.

    Very happy with the purchase and also received a nice cover to store it.

    Highly recommended!

    Super nice thing! The fan is super quiet and has lots of settings. It is remote controlled which I like extra! Easy to install.

    Only drawback may be that it is relatively low.

    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!

    Meanwhile, three fans from Duux in the house. I can't live without them anymore. With the heat, it's quite bearable... lovely breeze, almost noiseless.
    App and remote control work fine
