Powerful air humidification with a modern look
Thanks to cold evaporation technology, the humidifier enables powerful yet whisper-quiet humidification in your home. The intelligent automatic mode analyses the room air and adjusts the humidification to the desired humidity level. The filter drying function subsequently reduces the formation of bacteria and ensures long-lasting hygiene.

For the ideal indoor climate in your home

Energy efficient
The air humidifier uses efficient cold evaporation technology1 with a humidification output of up to 300 ml/h2 to enable natural air humidification while saving energy.

Hygienic humidification
The filter drying function can ensure even faster filter drying after use. This can reduce bacterial growth – up to 99.9% less bacteria.3

Night mode
The LB 300 Plus has a night mode with ultra-quiet operation and a switched-off control panel – the air humidifier can also be controlled with a timer from 1 to 9 hours.
1 Lower energy consumption compared to devices with hot water technology
2 Tested according to GB/T 23332-2018 in an independent laboratory. Starting temperature of 23±2°C and relative humidity of 30±2%.
3 Compared to standard ultrasonic air humidifiers which do not have any technology to reduce the spread of bacteria, tested by an independent institute.

Clean air thanks to cold evaporation technology
The evaporation filter soaks up water due to the capillary effect.
The dry air is drawn into the appliance by the fan and passes over the filter.
The water evaporates through the contact between the air flow and the moist filter surface.
The humidified air is then distributed evenly throughout the room by the fan.
Avoiding bacteria made easy
Customised application: After use, the filter drying function can ensure that the filter dries even faster. This prevents the formation of bacteria and makes using the humidifier even more hygienic.
