Important purchasing advice
We recommend a more powerful humidifier for Minergie houses (low energy or passive houses) or apartments for which calculations should be based on twice the room size.
The reason for this lies in the continuous exchange of air: cold and dry outdoor air is heated up and channelled indoors. The moisture produced by people, animals, furniture, plants, cooking, showering, etc. is quickly directed outside by the continuous exchange of air, usually resulting in extremely dry air indoors. Controlled ventilation systems therefore have the same effect as open windows.

Karl automatically selects the appropriate humidification level in auto mode to reach and maintain the desired humidity quietly and efficiently.
The 4-liter water container can be easily filled through a flap opening on the top, even during operation. When the water container is empty, Karl switches off automatically.
All functions of humidifier Karl can be conveniently controlled on the unit or via Wi-Fi using the Stadler Form app - including monitoring of the current humidity. This ensures an optimal indoor climate at home even when you are on the move.

It's beautiful, but also very powerful. For me, Karl is enough for my entire living room, which is probably 80 square meters. I think it could moisturize even more. The filling opening is rather small and difficult to hit...
Since the very start, I have had the privilege to co-develop and design products for Martin Stadler and the Stadler Form Team. What began with Fred, has grown into an attractive, small but fine range of products. This experience, and being part of the team, has greatly enriched myself and my work as a designer ...
