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.
Please read through the operating instructions carefully before you use the appliance for the first time and keep them safely for later reference; if necessary pass them on to the next owner.
- Stadler Form refuses all liability for loss or damage which arises as a result of failure to follow these operating instructions.
- The appliance is only to be used in the home for the purposes described in these instructions. Unauthorised use and technical modifications to the appliance can lead to danger to life and health.

Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.
- Only connect the cable to alternating current. Observe the voltage information given on the appliance.
- Do not use damaged extension cords.
- Do not run the power cord over sharp edges and make sure that it does not get trapped.
- Do not pull the plug from the socket with wet hands or by holding on to the power cord.
- Do not use the appliance in immediate vicinity of a bath tub, a shower or a swimming pool (observe a minimum distance of 3m). Place the appliance such that a person in the bath tub cannot touch the appliance.
- Keep the device away from heat sources.
- Do not place the appliance near a heat source. Do not subject the power cord to direct heat (such as a heated hotplate, open flames, hot iron sole plates or heaters for example). Protect power cords from oil.
- See to it that the appliance is properly positioned to ensure a high stability during its operation and make sure that no one can trip over the power cord.
- The appliance is not splash-proof.
- For indoor use only.
- Do not store the appliance outdoors.
- Store the appliance in a dry place inaccessible to children (pack the appliance).
- If the power cord is damaged, it must be replaced by the manufacturer or a repair shop authorized by the manufacturer or by similarly qualified persons in order to avoid a hazard.
- Be aware that high humidity levels may encourage the growth of biological organisms in the environment.
- Unplug the appliance during filling and cleaning.
- Never leave water in the water container when the appliance is not in use.
- Clean the water container every 3 days.
- Empty and clean the humidifier before storage. Clean the humidifier before next use.
- Warning: Micro-organisms that may be present in the water or in the environment where the appliance is used or stored, can grow in the water container and be blown in the air causing very serious health risks.
- Only use the adapter provided by the manufacturer.
- The appliance must not under any circumstances be operated with or come into contact with fragrances because these damage the plastic and may lead to appliance malfunctions.
Auto mode
Karl automatically selects the appropriate humidification level in auto mode to reach and maintain the desired humidity quietly and efficiently.
Easy handling
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.
Simple operation
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 may be that your external hygrometer and Karl are measuring different values because the devices have been positioned in different places (heights) in the room. Different humidity values will be measured depending on the air flow and temperature in each case. A tolerance of +/- 5 % is normal depending on the type of device. Karl measures the humidity levels best if he is positioned in the middle of the room so that the room air can flow towards the sensor as freely as possible. If that is not possible, we recommend positioning Karl against the wall, with a clearance of at least 30 cm. Under no circumstances should Karl be “hidden” in a corner of the room or behind a sofa/piece of furniture because this can have a negative effect on humidity measurement as well as humidification efficiency.
Ideally, you fill your Karl using the top filling opening. Of course, you can also fill Karl at the tap, but then you must be extra careful that no water spills during transportation.

Set the output to the highest level.
For the room size to be right, not only the room height (standard 2.5 m) but also whether or not the doors to the room are closed is a determining factor. If the doors to the room are left open, the adjacent rooms will also be included in the total area. If the relative humidity is low (below 35%), the humidity will not increase immediately. That is because the floors, furniture and walls absorb the moisture first before it ends up in the air. It can take up to two weeks for everything to absorb sufficient moisture for the humidity to start rising. As long as you keep having to top up the water regularly, your Karl is working properly.
If the humidifier filters are more than 2 months old or the upper part is hard and no longer saturated with water, the filters should be replaced.
For the hygienic and optimal use of the humidifier, the humidifier filter should be replaced at least every two months. If you continue to use the humidifier filter for longer than this, on the one hand the humidification output may deteriorate significantly and on the other, the antibacterial action of the filter can no longer be guaranteed. You can generally purchase humidifier filters from the place where you bought your device. The filter change indicator has to be reset manually after changing the filters.
Discolouration which is slightly yellowish or brownish is normal. Discolouration is caused by the substances in the mains water or the air. The poorer the water quality, the quicker the humidifier filter will become discoloured. Although this does not look pleasant, it is harmless as long as it is not due to mould. The discolouration will not affect the performance of your humidifier either. If you have not been using the humidifier filter for very long, you can rinse it thoroughly, turn it over and reuse it. If the humidifier filter is more than 2 months old, we recommend that you replace it.
It is also possible for the top part of the humidifier filters to become hard. During the evaporation process, the lime present in the water is collected in the humidifier filter as limescale. The harder the water, the quicker the humidifier filter will become hard. If you use water from a water softener which operates based on the principle of ion exchange, salt may collect in the humidifier filter rather than limescale. If you have been using the humidifier filter for less than 2 months, you can rinse it thoroughly with water, turn it over and put it back again. It is possible that you may notice an odour after you have turned over the humidifier filter depending on how contaminated the filter is by constituents in the air or the water.
If your Karl or the humidifier filters smell unpleasant, there may be various reasons for this: water and air quality, a worn-out filter or even the fact that you have not used your Karl for a long time and he has still water in his tank. In any case, we recommend that you clean and descale the device thoroughly. If you have been using the filter for less than 2 months, you can rinse it thoroughly with cold, clean water, turn it over and continue to use it.

Perfekt
Karl erfüllt sowohl ästhetisch als auch funktional unsere Erwartungen. In Kombination mit der perfekten Kaufabwicklung und dem sehr schnellen Versand resultiert somit eine uneingeschränkte Kaufempfehlung.
Review from Michael von Gunten at 07.02.2023Viel Power
Schön ist er, aber auch sehr leistungsfähig. Bei mir reicht Karl für mein ganzes Wohnzimmer, welches sicher 80 Quadratmeter gross ist. Ich glaube, er könnte auch noch mehr befeuchten. Die Einfüllöffnung ist eher etwas klein und schwierig zu treffe...

The Designer
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 ...
