3D humidifier with powerful katabatic humidity delivery (generated by HPK technology)
Available from Summer 2026: The 3rd generation of Necono 3D humidifiers –
featuring a confirmed patent application and compatible with all units manufactured since 2002.
What’s new is even more precise on-and-off cycles based on physical principles for the natural humidification process.
✔ The 3D humidifier by Necono AG is an electricity-free humidifier for living spaces up to 28 m². It works without a propeller, without ultrasound and without artificial misting – with a multiple award-winning system.
In other words:
✔ It moves up to approx. 475 m³ of air per day
and increases relative humidity by around 24%.
A special advantage, even in rooms with high ceilings:
the humidity first reaches the lower part of the room – where we breathe.
Customer feedback, 17 June 2026:
“We are extremely happy with the product: no electricity, it looks good and the effect in winter is enormous.”

Room with natural ambience, plants and 3D humidifier
WHO WAS THIS DEVELOPED FOR? – For people with high standards
- Families with children – safety
- Living spaces with controlled ventilation
- Design- and quality-conscious users – hygiene
- People who take healthy air seriously: breathing, skin and eyes
Use the technology!
All you have to do is fill in water. The system does the rest.
Cleaning once a year is a matter of course. Replacing the evaporation poster once per season and replacing the lime separators every 2–3 months is recommended (pack of 5). Minimal effort for maximum hygiene!
In 2021, we exceeded the mark of 10,000 devices sold!
Deliveries for DE and EU are carried out by the branch (DE-Rheinfelden Baden).
How the 3D humidifier works
the film lasts 22 seconds,
No standing water – everything is always in flux
THIS IS HYGIENIC – Hygienic because everything keeps moving + + +
- No permanent wet contact between evaporative fleece and water reserve
- No hidden humidity area
- Continuous replacement from and throughout the device
- the evaporation poster (fleece) is flooded with water and then completely separated from the water level again
- then the air is catabatically circulated
We wish you many refreshing days, months and decades with our devices !
Dry indoor air? We provide the solution – power-free, hygienic, and Swiss Made.
Dry heating air irritates mucous membranes, disturbs sleep, and damages wood and furniture.
Many humidifiers promise relief – but they are often noisy, power-hungry, or prone to contamination.
The 3D humidifier by Necono works differently:
-
No electricity & whisper-quiet – ideal for bedrooms and children’s rooms
-
Hygienic = healthy evaporation, no stagnant water, no ultrasound
-
Easy to clean and maintain – accessible and low-maintenance
- Patented HPK technology – natural air circulation driven by gravity, the 5. Method of humidification
-
Swiss Made & award-winning – proven for over 20 years
Advantages of HPK Technology
Efficient Performance
Our 3D humidifier increases the relative humidity (RH) of 475 m³ of air by 24 % – all without electricity.
This corresponds to a room size of approx. 28 m², based on seven air changes per day.
Hygiene through Technical Ingenuity – HPK!
It relies on HPK technology – short for Hydropneumatic and Katabatic. The result? Effective and natural evaporation for fresh, germ-free air.
Hydropneumatic Control:
Manages the availability of water required for evaporation! Precise regulation of water quantity based on air demand. Operates in intervals with active germ suppression. Ensures continuous humidification with dynamic evaporation performance. [More details here!]
Efficiency through Katabatic Airflow
Slower airflow at higher relative humidity – a natural physical law is at work!
Air Circulation
Many assume the 3D humidifier works like traditional radiator evaporators. But that couldn’t be more wrong!
Radiator evaporators release moisture upwards via warm air – the humidity accumulates at the ceiling, leaving the room dry below.
In contrast, the 3D humidifier directs moisture downward – delivering it exactly where it’s needed. It’s open and casing-free, efficiently mimicking natural free evaporation.
The air is continuously enriched in a dynamic, 3D-enhanced way – germ-free.
The key difference: continuous humidification with variable performance!

On the right: an IR image of the 3D humidifier – warm air is taken in at the top and directed downward in a controlled flow.

What do users say?
Message from a user (received March 19, 2024):
She’s from Germany, but currently active in Uzbekistan:
“Hello, I’ve already ordered from you and am very satisfied with my devices.
By the way: with an average humidity of just 15–20 % in Uzbekistan, the Necono manages to raise room humidity (45–60 sqm) to a much more comfortable 35–45 %!”
Our Plus: Repairs on the 3D Humidifier Can Be Done by the User
If something doesn’t work, we’re here to help. Here’s one such experience from a customer who has been using the product since 2014. He writes:
“Thank you, Mr. Kaiser,
for taking another look at the photos and identifying the issue.
I had reassembled the support arms incorrectly after cleaning.
It took just 7 minutes to fix – now everything works as before.
Best regards,
H………………. P…………. W………..”
These things happen – and fixing it is that simple!
When customers place an order, it might sound like this:

“Bonjour Mr. Kaiser, here’s my order, like every year.
I hope you’re doing well – I’m alright, although rather exhausted from work, xx xxxx xxxxxx xx xxxxxxx. It must be 18 years now that I’ve been using your humidifier posters, which I first discovered through Ventax A. F., where I used to work.
Kind regards to you and your team.
O.W.”
