Ultrasonic humidifier B 7 E
3-in-1 humidifier with aroma diffuser, integrated carbon air filter, anti-bacterial UV lamp and large 5-litre water tank
Healthy air and wellness for the airways
Breathe deeply and feel healthy! Thanks to a combination of refreshing humidification, permanent air purification and room air aromatization, the ultra-silent 3-in-1 ultrasonic humidifier B 7 E helps to improve the room air quality and maintain a healthy indoor climate with a wellness factor. The room humidity level is regulated fully automatically to a healthy comfort range (40 – 60 %), freed from dust, pollen and unpleasant odours in the integrated carbon air filter and, if desired, additionally aromatized with a subtle fragrance. The UV lamp in the water tank keeps the water clean and up to 97.9 % free from germs.
Why is air improvement necessary at all?
Whether we feel comfortable at home, sleep through the night or are receptive and productive at the workplace depends decisively on the quality of the room air. Room air that is too dry affects our well-being and promotes irritation of the mucous membranes as well as respiratory diseases such as coughs and colds. Particularly allergy sufferers and children with sensitive airways suffer noticeably from a poor room air quality. Optimally humidified room air in the range of 40 to 60 %, however, allows us to breathe freely. The oxygen uptake is increased, the mucous membranes, which are important for the immune defence, remain moist and the body's own defence system is permanently strengthened.
Enhance your health: stimulating aromas for your room air
For optional room air aromatization, the humidifier B 7 E with its living room-friendly design has an integrated scented oil tank. A few drops of essential oil are enough to pleasantly stimulate the entire body and to positively influence your general well-being.
5-litre water tank for up to 16 hours of health and well-being
And this is how it works: Ultrasound turns the tap water filled into the generous 5-litre water tank into a refreshing spray mist, which is distributed in the room by the mist nozzle. Three adjustable atomization levels and several humidification programmes (automatic mode/manual humidification/night mode) enable room air humidification for up to 16 hours. With its powerful atomization performance of up to 7.2 litres per day, the design humidifier B 7 E is recommended to be used all year long in living and working spaces sized up to 30 m² or 75 m³.
Increasing the humidity level to 50 % reduces the risk of transmission of viruses
Medical specialists have evaluated research findings relating to the resistance of viruses (e.g. SARS-CoV, MERS-CoV or SARS-CoV-2 (Covid-19), influenza) to air humidity. These findings have revealed that the humidity level has a crucial impact on the infectivity of germ droplets. Dry room air with a relative humidity content of less than 40 % lets tiny droplets infected with influenza or cold viruses dry up. This preserves pathogens so that they remain infectious for a very long time. In the optimum relative humidity range between 40 and 60 % aerosols only shrink so far that the salt concentration in the aerosol core increases, causing the germs and microorganisms contained to be killed. This minimizes the risk of an infection with influenza and cold viruses.
Medical specialists emphasize that we are able to reduce the risk of infection by increasing the humidity level in buildings. In this way, increasing the humidity level to approx. 50 % by humidification will reduce the risk of transmission. Moreover, the humidified air improves the body's defence situation by more efficient cleaning of the air passages and an improved immune defence. In modern buildings with a watertight building envelope, central heating and ventilation systems, these limit values can often not be complied with in everyday life without active humidification. This is where devices with a humidification function come in to provide assistance.
Healthy breathing air – optionally with beneficial fragrances
The B 7 E is equipped with a removable scented oil diffuser for the additional aromatization of the room air. A few drops of essential oil are enough to create a calm, tranquil room climate. Applied in the bedroom the ultra-silent B 7 E can facilitate a healthy night's sleep. In everyday life these scents, mobilizing the body's defences, help to relieve stress and to reduce our inner restlessness.
The curvy outline of the B 7 E, its ultramodern design in the white-and-silver colour combination as well as the optional on-demand illumination of the water tank can only be called a treat for the eyes, thus the stylish nebulizer harmoniously integrates into any area of life.
All in one for more health, quality of life and well-being
Whether at home in the living room, bedroom or children's room, in the spa area, in your office at home or elsewhere: the multifunctional humidifier B 7 E impresses in all environments as a powerful room air improver with a multitude of convenient comfort functions.
Scented oil tank: By adding health-promoting scented oils or aromas, you can create you very own oasis of well-being. The integrated aroma diffuser can help you to ease into relaxation mode at the end of a stressful day at work. A few drops of essential oil are all it takes to produce a mood-lifting room scent for a relaxing atmosphere.
Three operating modes (automatic mode, night mode, manual humidification): When the B 7 E is set to automatic mode, it conveniently and fully automatically controls the nebulizer intensity and thus the humidity level with its hygrostat control to a range that is ideal for your well-being. The manual operating mode with its three selectable humidification levels gives you the freedom to choose the humidification intensity yourself. For use in bedrooms and children's rooms, the humidifier comes with an ultra-silent night mode with deactivated display.
Energy-saving timer function: The 12-hour timer that can be programmed in increments of 1 hour is equally practical and energy-saving. It automatically switches the B 7 E humidifier on or off after a preset time. In this way, the operating time of the device can be individually adapted to working hours in the office, time spent with your loved ones or bedtime in the children's room.
Anti-bacterial UV lamp: An anti-bacterial UV lamp ensures reliable protection against bacterial growth and germ infestation in the water reservoir. The water is permanently disinfected and demineralised by up to 97.9 %.
Intuitive touchscreen: The B 7 E can be controlled via a touchscreen control panel at the front. All parameters such as humidity, nebulizer intensity, programme selection etc. are displayed in an easy-to-read manner.
Automatic switch-off when water tank is empty: A warning LED in the display informs you of a low water level in due time so that you have enough time to add water. Once the water in the water tank is used up, the humidifier B 7 E switches off automatically.

Optimally humidified room air protects against viruses and pathogenic germs
Scientific studies prove the double protective effect of an optimally regulated indoor air quality in infection prevention. Pathogenic viruses such as the influenza or SARS-CoV-2 virus are released via so-called aerosols when we breathe or speak, and can remain suspended in the room for up to several hours if there is insufficient ventilation. Invisible, but still highly infectious.
At an ideal humidity level between 40 and 60 %, airborne viruses are inactivated within seconds
The infectivity of virus-infected aerosols depends decisively on the prevailing humidity level. If the room air is too dry, aerosols shrink and float in the room air for a longer time due to their low weight – before being inhaled unnoticed. Optimally humidified air, on the other hand, changes the salt concentration of the aerosol particles so that the contained pathogen becomes harmless immediately after contact with the air.
Optimally moistened mucous membranes are the best and most natural infection protection against pathogenic germs in the air
The body is not defenceless against the dangers of viruses and bacteria. It has its own defence mechanisms to protect itself against pathogens in the air. The mucous membranes of the mouth, nose and throat of our airways are a central component of our body's own immune defence and, when optimally moistened, provide highly effective protection against pathogens in the air. Too dry room air, on the other hand, withdraws the necessary water from the mucus layer, so that the previously protective mucus layer becomes hard and infectious pathogens can penetrate the body almost unhindered.
Therefore, increasing the room air humidity to around 50 % minimises the risk of infection by airborne pathogens in multiple ways in the private and professional environment.
SecoSan – always the best water quality for refreshingly humidified room air
Continuous fresh water supply to ensure a healthy air quality.
To keep the water storage tank automatically as clean as on the first day, we recommend using a SecoSan stick which keeps the water permanently clean, clear and free from germs or unpleasant odours. The unique feature of SecoSan is its antimicrobial surface with mobile silver ions, which inhibit bacteria and germs upon contact and thus prevent their reproduction. The entirely self-dosing SecoSan ion reservoir keeps the water demonstrably free from germs. The stick thus guarantees clean water for up to 6 months even if the water is changed or consumed daily.
