The ultimate fan, completely smart

Whisper Flex has a remarkable 26 speed settings, multiple modes, and a powerful motor with double fan blades. All these functions are performed while remaining whisper-quiet from only 13dB.

With the free Duux Smart app, you can control your Whisper Flex Smart with your phone, so that your room is nice and cool when you get home. Or, use voice assistance including Amazon Alexa or Google Assistant.

Whisper Flex Smart has 15 metres of wind reach with a running cost of <1p/hour on the highest setting*, cooling even the largest spaces efficiently. Adjust the multiple modes to your preference, including natural breeze mode to simulate real wind.

Whisper Flex Smart reaches every corner of the room oscillating 90⁰ horizontally and 100⁰ vertically.

In night mode, the screen automatically dims so that you are not disturbed. The timer can be set from 0-12 hours and switches off automatically.

Whisper Flex Smart also has intuitive controls including a rotary dial with LED display and a convenient magnetic remote control (for when you don’t feel like getting out of bed!).

A minimalistic design with a matte finish that fits seamlessly into any décor. Adjustable height, allowing you to effortlessly transition from pedestal (88cm) to tabletop (51cm), by simply removing the extension. The convenient magnetic remote control can be stored on the back of the fan.

The compatible dock and battery pack are available separately and allow you to turn Whisper Flex into a portable fan. The battery has a life of up to 12 hours, depending on 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.

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

    Meanwhile, Three Duux fans in the house. I can not live without. It’s easy to bear the heat … Lovely Wind, Almost Silent.
    App and remote control work fine.

    I bought them about two months ago, the app was a bit Difficult. But by Splitting the WiFi Into 2.4 and 5, It is then easy to set up. Fan is Quiet and the Functions Are Easy To Operate, Especiate If You Don’t Want It To Run All Day. Recommended!

    Super Fan, it is so quiet, fully adjustable by turning the app works great, connecting can be a bit difficult, but once it works you no longer need a remote control. Night Mode is nice that the lighting turns off on the button, no bad becomes about this fan, the best one I know. In Terms of Quietness, Duux’s Service If There Is Something Wrong With Your Fan is also Top Notch

    Super Chill Thing! Very Surprising How Quiet The Fan is. Beautiful Design and Super Chill That It is Smart.
    The only Disadvantage May be that it is not very long.

    Very Beautiful Thing! The fan is super Quiet and Has Many Settings. It has remote control which I really like! Easy to Install.
    The only Disadvantage May be that it is relatively low.

    Very happy with this purchase. I had carefully looked at the reviews of Various fans in Advance. Ultimately, I Opted for a Tower Fan for the Nursery. Unlike the Others, I am super satisfied with this one. Very Powerful, Many Functions, The Head Can Rotate in Many Positions and the Program for this is Excellent. The Controls are Logical, Even Those On The Stand Itself. Whisper Quietly and a Big Plus that makes it stand out from Many Others: it can be dismantled, so easy to store in the winter.

    Very nice fan from Duux. This is the first fan (and I’ve tried many) that is really quiet. IDEAL for the bedroom. It has settings from 1-26, but at setting 4 it is still quite quiet 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 produces just a little 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 one of the fans I found the fan blade was not a complete centered, causing it to vibrate a bit. Just Called Duux Support and They Resolved This Perfectly. Operation with the remote control is very simple. You can also operate the fan on the fan itself. This is also easy, althegh you do need to understand how it works. All in all, very satisfied with this fan, both the flex and the flex smart.

    Great fan. We have the model with a battery and a plug. It can only run on the battery and if it runs out, you can run the fan on electricity and the battery will be recharged at the same time. 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?

    I Purchased a Whisper Flux Smart because it produces Very Little Sound. I am very happy with it, it is also very quiet, another advantage, it uses very little power on setting 12 but just 8 watts. Very Good Quality. I am very happy with this purchase.

    I have had a duux whisper flex in my home for 2 weeks now (via Bijenkorf). The Bedroom Cools Down Quickly and Even On The Highest Setting You Can Hardly Hear The Device. Very Happy With the Purchase and also Received a nice cover to store it. Highly Recommended!

    Blows Quietly and Louder than expected. A really great thing. The Remote Control is also really useful. I have no idea if the app is useful, I can’t figure that out here. Overall definitely WORTH THE MONEY. Double Swing Function, and 26 Wind Speeds. IDEAL to have next to the bed because of its quiet motor

    A Super Quiet and Nice Fan. Best purchase of the year so far. I have a very hot cream (read 30 degrees when it’s hot outside) and I can’t sleep because of the noise of normal fans. This blows hard and is Quiet. The fan can also blow in all directives, so that the air flow in the room remains good. In Addition, there is also a function to get a natural wind, which is super nice (close your eyes and it’s just like you’re lying on the beach). It is also great that you can operate the fan via both a remote control and an app on your phone.

    Because it get a bit warm in the attic, we decided to buy a fan. Looking for a fan that Doesn’tn’t Make a lot of noise (That Sleeps Better), is sturdy, has a display that can be turned off at night, can move both horizontally and vertically and can be controlled remotely (with remote control, but I much prefer to use the app), then you will quickly end up with this duux. Not the cheapest, but the quality is more than worth it. Don’t Hesitation, Just Buy!
