An Oasis of Cool and Quiet
Imagine a cooling breeze that follows you into every corner of your home. Whisper Flex Ultimate is an incredibly versatile, wireless fan that will transform any space into a cool oasis while remaining whisper quiet. So when a the heat kicks up, set your perfect temperature and enjoy the breeze.

Beautiful and smart design
Whisper Flex Ultimate has a sleek, minimalist design with a matte finish. The fan is available in monochrome black or white. Easily portable thanks to its elegant, slender neck, and the extra height allows for better reach (such as over high beds!) if you want to turn the bedroom into a cool oasis, too. The remote control can be stored in the convenient slots on the front and back.

Whisper quiet with an unprecedented range
Thanks to its double fan blades, this energy efficient beauty has 17 meters of wind reach, cooling even the largest spaces. You can adjust the 30 speeds to your preference or simply set it on auto mode. A sensor allows you to choose your ideal temperature so the windspeed can adjust accordingly, all while remaining whisper quiet (only 13 dB!). Automatic charging on the docking station provides up to 12 hours wireless usage.

Like Natural Wind in Every Direction
Its multi-directional oscillation moves not only horizontally and vertically, but rotates in both directions: an impressive 90⁰ horizontal and 105⁰ vertical tilt with three intermediate settings each. The Natural Wind Mode mimics real wind, alternating from a light breeze to a strong gust. The zero to 24 hour Timer Mode features automatic shutoff, and Night Mode automatically dims, ensuring you are not disturbed.

Smart Controls at Your Touch (or Voice!)
Whisper Flex Ultimate offers intuitive controls including an on/off touch button, a twisting control knob with LED display and a detachable remote control (for when you don’t feel like getting out of bed!). Along with your free Duux smartphone app, you can also control the fan with your phone or with assistants like Alexa/Google Assistant so your room can be cool when you get home.

    I am disappointed in the Duux Whisper Flex Ultimate I recently purchased. I expected it to be better than the Whisper Flex Smart, which I had a great experience with. Unfortunately, that does not appear to be the case.

    The problem is that the fan feels wobbly because of its "gooseneck," so I decided to send it back.

    I am going back to the cheaper Whisper Flex Smart fan, which does meet my expectations and is stable.

Duux Smart App

The Whisper Flex Ultimate has plenty of intuitive control options, such as the aluminium dial with its high-resolution LCD screen in the middle of the interface. Oh yeah, you don't have to get up: you just control Whisper Flex Ultimate with the Duux smartphone app or the remote control, which you magnetically snap into the neck.

Whisper quiet

Whisper Flex Ultimate lives up to its name. With a minimal noise production of only 13 decibels, this fan is barely audible. Natural Wind Mode alternates between wind speeds to simulate real wind. Night mode ensures a good night's sleep with minimal noise and an auto-dimming screen. In addition, you can let Whisper Flex Ultimate choose its own speed with the temperature-controlled mode.

The extension piece transforms the Whisper Flex Ultimate from a table top model (58 cm) into a floor standing model (103 cm). It is height-adjustable and, with its horizontal and vertical swing, effortlessly transforms from a table model to a floor model. And the best part? It is whisper-quiet, so you can concentrate on that one book or sleep in peace.

Clever front and back slots allow for easy remote control storage.
