Keep your air healthy by regularly replacing the filters in your evaporative humidifier. Pack of 4 filters compatible with the OSKAR and KARL range.
Data sheet
The color change is due to the components of the tap water or air. The filters change color more quickly depending on the water quality. This is not very aesthetic, but as long as it is not mold, it is harmless. On the other hand, filters affected by mold should be thrown away and the device should be cleaned thoroughly. If you have recently changed the filters, you can rinse them, turn them over and continue using them. If you have been using the filters for more than 2 months, replace them with new ones. Please note that the color of the filters has no influence on the normal operation of the humidifier.
We recommend changing them approximately every 2 à 3 months.
For a successful installation, the water level sensor must be placed high enough, above the suction point of the pump. It should be securely fixed, upright, and not in contact with the sides of the tank, so it can accurately detect rising water. This correct positioning ensures the pump activates at the right moment and drains water efficiently without running dry.
On the other hand, a poorly positioned sensor — too low, tilted, or stuck against a wall or cable — may cause detection errors. The pump might turn on too early, with no water, or fail to activate at all. This can lead to system damage or overflow. The visuals below clearly show what to do… and what to avoid.
