Three years after the first Williwaw (to cool down the attic bedroom), we’re doing it again (living room) as the hot weather approaches. Quiet, efficient, attractive…and repairable if ever needed—the only thing that gives pause is the price (up 20% since 2020, like so many things). But when you compare it to other solutions (an air conditioner, for example), the math is easy. For installation, a video explains everything (15 minutes). And as a side note, regarding customer service, my first interaction was remarkable—the device’s creator called me directly to answer my question…

Purchased in 2020, this fan is excellent, if not better. Its standout feature is its quiet operation, and another key feature is its truly refreshing breeze. These qualities are especially appreciated during those hot summer nights. Finally, the customer service is outstanding. A minor malfunction—I left a message on the Williwaw website and received an immediate response. Mr. Thirouin came out personally, and the repair was done in a flash and at no cost, three years after purchase! I recommend it without reservation.
BAZIN (long-time customer) – September 12, 2022
I received mine last Thursday and I already can’t live without it!
Turning it on is the first thing I do when I get home, whether it’s hot or not. Silent and powerful, it adds a touch of comfort to my interior.
Julien C (Verified Customer) – June 17, 2019
Received yesterday. Assembled in 10 minutes (it would have been even faster if I’d actually watched the video…) Otherwise, a beautiful product, truly powerful and silent.
You can feel the attention to detail throughout, which is a real pleasure…
Nicolas M (verified customer) – June 8, 2019
After more than a month of use, including several very hot nights, the whole family is convinced.
It is truly silent without compromising on the power needed to cool down during heatwaves.
Arnaud J (verified customer) – September 30, 2020
We ordered the fan right after visiting the Paris trade show; shipping was super fast, and installation was very easy by following the videos.
My daughters were very skeptical about my purchase, but now they’re asking me to set up the fan to cool down their rooms at night. I’m even thinking of investing in one for the upstairs next year. I have absolutely no regrets about my purchase—except maybe that I didn’t buy two of them!!!
Suhard (verified customer) – August 4, 2022
This is the third one I’ve bought. We have one in every bedroom, and we no longer dread the heat waves at night.
It’s completely silent and provides a refreshing breeze!
We would never have invested in an air conditioner out of environmental concerns, but this product won us over. It’s an investment, but one that’s well worth it—especially since it also runs in the winter in the living room with a loft and helps regulate the room’s temperature. And he’s so handsome!
Carole LASSALLE (confirmed customer) – July 6, 2022
Using only 5 watts to cool, compared to 2500 watts for an air conditioner, Williwaw features a powerful and silent motor.
It is the ecological solution for peaceful nights, even during heatwaves.
The Williwaw’s 9-blade propeller produces two to three times less noise than its competitors, offering a peaceful solution to scorching nights.
Noise level (to EN60704-2-7) :
Its strengths? Connected, stylish, and comfortable.
Its remote control? Your smartphone.
Williwaw adjusts to your needs, from a gentle breeze to a strong wind. With an oscillation range from 45 to 270 degrees and 3 speeds, it ensures a tailor-made experience.
Controlled via a mobile app for iOS and Android, Williwaw is a smart destratifier fan.
Adjust its wide, slow airflow remotely for optimal comfort without the mess—no more flying papers!
Equipped with a swivel head and external temperature sensors, it ensures gentle, silent convection, which is automatically activated when there is a significant temperature difference between the floor and the ceiling.
This translates into a 30% reduction in heating costs in the space occupied by the Williwaw.
Williwaw’s temperature sensors detect heat differences between the floor and ceiling. When a gap is identified, it creates convection to balance the temperature.
This improves comfort and reduces energy consumption by allowing the heating to turn off more frequently. Control and programming are easily managed via the mobile app.
Crafted from steel, beech wood, and polycarbonate (the same material used in bulletproof glass), and assembled with screws, Williwaw is engineered for longevity.
Every part is replaceable, the blade is dishwasher-safe for easy cleaning, and the mechanical components are backed by a 10-year warranty.
By balancing the temperature, Williwaw eliminates hot or cold spots, enhancing comfort in open spaces, meeting rooms, or offices.
Even at low speeds, it provides a refreshing breeze without blowing papers around.
Durable in the truest sense. By choosing polycarbonate—the material used for bulletproof glass—for its plastic parts, along with metal and beech wood, and opting for a screw-based assembly, Williwaw features:
What’s more, in the event of a breakdown, the electronic board can be replaced at cost price, thanks to a connector system that avoids the need for soldering, thus facilitating repairs.
2 possible heights to be selected prior to assembly depending on the number of foot segments
But what else?
Assembly without clipping, gluing or welding.
Invisible, 115 screws ensure sturdiness and total repairability
A Williwaw projects its air stream up to 8m50 away, and sweeps up to 270 degrees. It covers an area of 170 m2
I am Stéphane Thirouin, a designer driven by a passion for creating useful, durable, and aesthetically pleasing objects.
Faced with an oppressive heatwave and wanting to avoid air conditioning for ecological reasons, yet disappointed by the efficiency of available fans, I set out to develop Williwaw: a fan that combines silence, power, energy savings, and longevity.
Editing Williwaw is a breeze
Destratifiers like Williwaw optimize heating by redistributing warm air from the ceiling down to the floor, reducing the load on your heating system.
For a space with an annual heating bill of €1,500, the absence of a destratifier leads to uneven air distribution, with heat trapped at the top and cold air at the bottom.
Using Williwaw mixes the air, limiting the need to overheat. This leads to 30% savings, lowering the bill to €1,050—a reduction of €450 per year. Factoring in Williwaw’s power consumption, the net saving is €430.
The benefits extend to summer as well; Williwaw eliminates the need for energy-hungry air conditioning, offering annual savings thanks to its low power consumption.
Here is an overview of the savings achieved with Williwaw to cool a 40m² space with a 4m ceiling height.
An air circulator, a destratifier, and a fan all aim to improve thermal comfort but differ in how they operate and are used.
A fan creates a directed airflow toward a specific area, providing an immediate cooling sensation on the skin through sweat evaporation. It is ideal for targeted, personal cooling.
Air circulators are often used in industrial settings. Their goal is to mix the air in an entire room, promoting uniform temperature and air distribution. They can reduce temperature gaps in a space, making it more comfortable overall.
An air circulator is designed to move large volumes of air through a room or open space, creating a fresh breeze that improves the feeling of comfort without necessarily lowering the ambient temperature. It is ideal for ventilating and cooling large areas due to its ability to circulate air efficiently.
With its ability to move large volumes of air, an air circulator is often used in larger spaces or for industrial applications, while a fan is better suited for home or office use.
A destratifier, on the other hand, aims to homogenize the temperature in a space by redistributing the warm air accumulated near the ceiling toward the floor, thus reducing the temperature differences between stratified air layers. This not only improves thermal comfort but also generates energy savings, particularly in heated spaces, as it reduces the need for additional heating.
To clean your Williwaw, follow these steps:
Your Williwaw is clean and ready to go!
Air conditioning | Williwaw | |
|---|---|---|
Purchase + installation costs | €5,350 | €999 |
Cost of monthly electricity consumption | €5,984 | €953 |
Total cost over 1 year | €6,705 | €969 |
Total cost over 5 years | €120.96 | €1.01 |
Position the Williwaw fan strategically to optimize airflow in the room.
For optimal comfort, ideally place it a short distance away from the walls to allow air to circulate freely.
In the summer, position it so that it directs a cool breeze directly into living areas. To distribute heat in the winter, set it to de-stratification mode and place it near a heat source to circulate the warm air that has accumulated near the ceiling.
The location may vary depending on the season and the layout of your space.
Choosing the ideal fan involves considering several factors, including power, noise level, and additional features such as a timer or oscillation.
But on the market (up against Dyson, Rowenta, and Honeywell), the Williwaw stands out for its quiet operation, sleek design, and powerful performance.
For effective cooling, check the airflow and whether you can adjust the fan speed. The price will reflect the technology, features, and durability of the product.
Quiet fans are ideal for working or sleeping without being disturbed; some models feature adjustable height or angle settings, ensuring complete comfort.
The number of Williwaw fans required per room varies based on the dimensions of the space, ceiling height, and the device’s efficiency.
Thanks to its high power, a standard home or office room only needs one properly sized Williwaw to evenly distribute hot or cold air.
For large spaces or those with complex layouts, installing multiple units may be necessary to achieve peak efficiency.
