Immerse yourself in an oasis of coolness and quiet

Silent as a Whisper & Blissful as a Breeze
Imagine a cooling breeze that follows you through your home wherever you go. Bringing blissfully fresh air into every corner of your hot, stuffy house and transforming it into an oasis of coolness. Introducing Whisper Flex Ultimate: an incredibly versatile, energy efficient and powerful fan that can be adjusted to your perfect temperature while remaining whisper quiet. And it goes everywhere you do, with a 12 hour rechargeable battery providing wireless mobility throughout your entire home and beyond. Bring in the breeze!

Beautiful, Clever Design

With sleek, minimalistic design and a smooth, matte finish, Whisper Flex Ultimate is offered in monochromatic black or white. Its elegant, swanlike neck allows for easy mobility and the newly increased height provides better reach (like over those high beds!) for when you're ready to move your oasis into the bedroom. Clever front and back slots allow for easy remote control storage.

Quiet as a Whisper with a Powerful Reach

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.

    Bonjour, je suis très heureuse de mon achat. Effectively, it is design, and above all it gives a very pleasant fragrance and is quiet. I love it. Cependant j'ai une question: la batterie se décharge rapidement dès qu'il n'est plus sur son socle, mais également en mode OFF!? The battery discharges even when it is not working. This is not nice in the middle of the night. Is this normal?

      Merci pour la critique !

      Le ventilateur n'est jamais vraiment éteint. Comparez cela avec votre télévision. Il est également en veille lorsque vous l'éteignez avec la télécommande. Cela consomme un peu d'énergie, mais pas beaucoup. Si vous estimez qu'il consomme trop d'énergie en veille, veuillez envoyer un courriel à [email protected] et nous pourrons examiner la question.

      Nous vous recommandons également de retirer la batterie si vous ne comptez pas l'utiliser pendant de longues périodes. De cette façon, il dure le plus longtemps 🙂

    I have had a Duux Whisper Flex for two years now and I am still very happy with it. When I wanted to buy an extra fan this year, I saw that Duux had introduced an even more luxurious model in this series, which made my choice easier. I really think this is the best fan out there. It's quiet, horizontal & vertical oscillation, can be used anywhere because of the battery, can be controlled with the app, can be controlled with Google home.

    I think this is the best fan available at the moment.

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.

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.

Very energy efficient

Besides being quiet, Whisper Flex Ultimate is also very energy efficient. Over a whole day, the fan uses only €0.03* (!) in energy costs per day! This is less than €11 on an annual basis. (* 5W consumption, setting 8, € 0.22 / kWh)

Durable & modular
