Product information Oskar

Optimally humidify the air with low energy consumption; humidifier Oskar is the one to call in! Oskar humidifies rooms up to 50 m2. The economical evaporator provides exact humidification thanks to his hygrostat.

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.

Dimming function

Oskar is also suitable for the bedroom, where the humidifier works almost unnoticed. His LEDs can be dimmed or switched off.

Easy filling

Thanks to the filling opening, Oskar can be refilled quickly and conveniently, even during operation. When its tank is empty, it automatically switches off.

Memo function

Changing the filters is often neglected or forgotten, so Oskar has a memo function that reminds you to change the filters.

For hygienic reasons and to ensure proper operation, we recommend the following cleaning intervals.
Attention: Never immerse the device in water (danger of short-circuit).

Daily: Fill the device with fresh, cold tap water. If the device is not going to be used for several days, empty the water from the lower part beforehand and if necessary, clean it with a drop of washing-up liquid and a clean cloth. Fill the lower part with fresh water before putting the device into operation again.

Every 2 weeks: First remove the filters and the Water Cube™. Clean the inside of the lower part thoroughly every 2 weeks using a drop of washing-up liquid, warm water and a soft, clean cloth, sponge or brush. Then rinse out the lower part thoroughly with cold water and put back the filters and the Water Cube.

Approximately every 4 weeks (depending on the water hardness in each case): First remove the filters and the Water Cube™. If there are limescale deposits inside the lower part, we recommend that you use Stadler Form Cleaner & Descaler. Alternatively, you can use a household descaling agent or vinegar. Then rinse out the lower part thoroughly with cold water and put back the filters and the Water Cube. For hygienic reasons, the filters should be replaced every 2-3 months.

Video Cleaning

Regularly as required: To clean the outside, rub with a damp cloth and then dry thoroughly.

At the end of the season: Before putting away the device at the end of the season, clean it thoroughly inside and out and let it dry completely. Descale the lower part as described above. Clean the fan blades in the upper part with a damp cloth and then wipe them dry. Insert new humidifier filters and a new Water Cube so that your device will be ready to be put into operation at the start of the next season.
The intensity of the fragrance is influenced by various factors:
  •     Type of fragrance (synthetic, natural, ingredients, etc.)
  •     Room temperature and relative humidity (the more humid the air, the stronger the fragrance will be)
  •     Room size (the smaller the room, the more intense the fragrance)

In principle, you can increase the intensity of a fragrance by adding a little more fragrance oil. The strength of a fragrance will depend on the fragrance itself. Natural fragrances are often more discreet than synthetic ones and certain ingredients are more dominant than others.

It should also be remembered that first and foremost, the device is a humidifier. Its main focus is to provide humidity in the room and because of that, the intensity of its fragrance will never be as strong as the fragrance from an aroma diffuser.
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. Press and hold down the reset button for 5 seconds until the blue LED is continuously illuminated again. Video Filter Reset

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 Oskar 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 Oskar 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 (Link: Cleaning). 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.  

Please start off by checking that the float gauge (see A) can move up and down. It may be that it has become stuck due to excessive limescale/dirt. Descale the water tray regularly in order to ensure fault-free operation.

Oskar consists of two parts: an upper part and a lower part. If the upper part is not seated properly on the lower part, the float gauge sensor will not make contact with the electronics in the upper part. Seat the upper part correctly to restore contact.

If neither of the two cases above apply, lift off the upper part and clean the contacts (see B und C) with a damp cloth. Then dry them thoroughly and put the upper part back on the lower part.

This FAQ only applies to devices produced before June 2022 (SN: number 22 06 xxxxx). Devices with a production date of June 2022 and lager are not affected by this problem. If you have one of these devices and this problem occurs, please contact our customer service department. 
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 Oskar is working properly. If the humidifier filter is more than 2 months old or the upper part is hard and no longer saturated with water, it should be replaced.
It may be that your external hygrometer and Oskar 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. Oskar 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 Oskar against the wall, with a clearance of at least 30 cm. Under no circumstances should Oskar 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.
