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 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 table to floor thanks to its horizontal and vertical swing. And the best part? It is whisper-quiet, so you can concentrate on that one book or go to 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.

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.

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.

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 dock and battery turn Whisper Flex into a true wireless fan. The battery lasts up to 12 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.

Yes, this is possible. A power cord is supplied as standard.

    Ich besitze den Ventilator jetzt ein halbes Jahr und bin maßlos enttäuscht. Positiv anzumerken ist, der Ventilator ist leise und kräftig. Folgende Punkte sind mir negativ aufgefallen:
    -die App und der Skill für Alexa funktionieren völlig unzuverlässig, somit ist die Smart-Home Funktionalität nicht gegeben
    -Reaktion auf Sprachbefehle dauern mindestens 3 bis 5 Sekunden und erzeugt oft einen Timeout
    -Ventilator entfernt sich regelmäßig selbständig aus der App und muss manuell neu eingebunden werden
    -sehr wenige Funktionen über App und Sprachsteuerung
    -App hängt sich auf und reagiert nicht

    Diese Probleme häufen sich, so dass es einfach unmöglich ist den Ventilator smart zu bedienen. Über die Fernbedienung funktioniert es.
    Der Support ist zwar freundlich, kann allerdings nicht helfen!

    This summer use the fan used. A huge difference from the usual (cheaper) fans. Hardly audible at lower settings. Great purchase.

    The fan is quiet and does the job nicely.

    Setting up was not easy, as it could not use the standard WiFi, i had to setup a guest WiFi network.
    The app needs to communicate with duux servers to change settings on the fan, meaning the fan needs internet access and can't use the local network.

    The firmware on the fan can not be updated, which means if/when there is a vulnerability in the fan software, are stuck with a potential breach into your network. That's particularly bad as the fan needs internet access for smart app connection.

    Had I known above, I wouldn't have purchased the fan.

    With high expectations today bought a grey Duux . Design, maintenance, sturdiness, sound etc perfect.
    What we are very disappointed with is the oscillation speed of the fan, which makes it take a very long time before a cooling breeze comes along. At speed 26 it is very slow. We will watch it, but as we experience it now we bring the device back. Based on the assessment of the Consumers' Association, we are therefore disappointed.

    A top device! Am really very content with it. Nice addition when you don't have air conditioning at your disposal.

    Easy to charge wirelessly and use for hours. Is also very quiet and pleasant temperature.

    Very satisfied!
    We bought a second unit to use in different bedrooms.
    I sleep like a baby when I use the appliance on position 1.
    The device is very quiet and therefore not disturbing while sleeping.
    With the second appliance I bought, the remote control did not work properly.
    After contacting customer service, I received a new remote control very quickly.
    I am very satisfied with the device, but also with the customer service of Duux.

    It works really quietly, only a pity that it only works on the 2.4 band and not on the 5 GHz WiFi.

    A great fan with 26 adjustable speeds.
    Very quiet at the lower speeds, making it perfect for use in the bedroom on warm nights.

    The supplied remote control works on infrared.
    You therefore need a line of sight to the receiver.
    The receiver is integrated in the base and it can be difficult to operate the fan if there is an object in front of the base.

    However, integration as a smart device has failed.
    The fan only supports 2.4 GHz WiFi.
    It's not that the speed of 5GHz is necessary but it would have been nice for the usability of the product if it had gone along with modern standards that both were a possibility.

    I have created 2 separate SSIDs on my router. One for 2.4GHz and one for 5GHz.
    I had to temporarily change the "Wireless Mode" setting on my router to "Legacy" instead of the default "Auto".
    Without this specific setting, the fan would not connect.
    Once connected, this setting can be set back to "Auto".
    Be careful when pressing the dial. If you hold it down for 5 seconds the device will reset and you will lose all wifi settings again.

    The app itself has few settings.
    I have Google Assistant which I can use.
    The fan only has 4 commands for Google Assistant.
    Switch On, Switch Off, Increase Speed & Decrease Speed.

    If your fan is at level 1 and you want to increase it to 15 via Google Assistant, you will have to give the command "Increase Speed" to Google Assistant 14 times.
    Within Google Assistant, there is no specific command to immediately set the fan to a specific speed setting.

    When I bought it a year ago, I contacted Duux about it.
    They sent me an email telling me to keep an eye on the app because there are regular updates.
    You can also find this in the app:

    Voice Commands.
    Here you will find an overview of the voice commands per device that are currently supported.
    Please note we are adding new commands on a regular base. Last update: 26/04/2020.

    So nothing has been updated here for a year.
    Alexa has more voice commands available.

    The vertical and horizontal swing is nice, but unfortunately it cannot be limited to a specific position.
    If you turn on this swing position, the fan will do the full range both vertically and horizontally.
    This is a missed opportunity, it would have been a very nice feature if this could have been adjusted via the app to set the most effective range of the fan.

    If you have a battery with the fan, you cannot turn it off completely.
    When you turn the fan off, it stops running but the display on the base remains on.
    If the fan is connected to the wall socket, it will always remain in this energy-inefficient mode.
    If the fan is connected to the battery, the display will also remain on until the battery runs out.
    With the functionality of wifi and remote control, I understand that the device needs to be in some sort of standby mode.
    It just would have been nice to have an option to turn the fan off completely without having to unplug it and let the battery or battery fully discharge if you leave it in.
    Now it remains an energy-inefficient device in standby mode.

    Beautiful fan but the smart functionality is poor.
    The fan was put on the market for a considerable price. You would expect that functionality will be further developed through application and firmware upgrades.
    However, this is not the case.

    You are better off with the ordinary Duux Whisper . This one is around 120 euros at the moment of writing.
    For 210 euros for the Whisper flex with battery you can really expect more from the smart functionality.

    Best fan I have ever had but the smart functionality and shortcomings irritate me immensely.

    A great fan. I enjoyed it a lot last year. Just installed it again and it cooled me down immediately. Unfortunately, the app no longer connects on the iPhone and IPad which both work on 5GHz. Fortunately, there is the old-fashioned remote control. I'm curious about the new Ultimate.

    Works great! Easy to operate via smartphone or Googlehome. Configuration very easy. Also the whisper flex button works very handy. Multifunctional use as for example bbq today. I have two whisper flex On battery set to position 9 that blow over the table and therefore not a single fly on our salads and meat to be seen. A relaxed and tasty meal. Afterwards, I put them in the bedroom and bathroom, so I can bring in fresh air from outside. No more of the loud noise from the mobile airco "wishper"? As they call it.
    The Duux whisper flex smart is really quiet. Great device! And ordered Sunday delivered Monday 8:30. Classy! Thank you very much, highly recommended!

    Whisper-quiet fan that ensures a good night's sleep. In the lowest (two) setting(s), you hardly feel "that the wind is blowing", but I find that very pleasant. The app works very well and quickly. Connecting it was a breeze.
    Very solid material. It costs a bit, but then you have a top fan.

    Great fan. Assembled. Turned on and immediately bought the little one. It's super quiet. Got two little dots. I would have liked it a little higher. Would be ideal if in the future to order a rod in between so you can put it 20/40 cm higher. And the infrared point on the base is not very handy for the remote control. Luckily I have the app and I don't need it.

    Have had this fan for a few days now and can't think of any negative points. Extremely quiet, even on position 5 or 10. The rotating head is ideal for the bedroom so that you are not always in the air flow. App control is very fancy, so you don't have to get out of bed. In addition, the design is very nice and the workmanship high quality. Probably going to buy a second one for our son's bedroom. Top product!
