Ultrasonic humidifier B 3 E / B 4 E
3-in-1 humidifier with carbon air filter, UV lamp and aroma diffuser for improving the air quality
An agreeable humidity level and aromas for a healthy room climate
Too dry room air has a considerable impact on our physical health and our general well-being. Irritated eyes, dry skin, headaches, respiratory infections as well as restless sleep may be the effects of a too low humidity level. Especially in autumn and winter, dry heated air impairs our well-being in a particularly unpleasant manner. The living space-friendly ultrasonic humidifiers B 3 E and B 4 E provide a quick and durable solution to get rid of these effects and other impacts of too dry air.
Black or white – good room air always in vogue
On the outside, the identical devices B 3 E and B 4 E merely differ with regard to their housing colours. Everything but colourless, the white B 3 E humidifies and cleans the air in living and office environments and, in doing this, convinces by its timelessly elegant appearance. However, if you wish to add an optical extra touch, go for the B 4 E which represents classy purism with its matt black finish. What both devices have in common is the innovative combination of humidification and air improvement to humidify the room air and breathing air in rooms sized up to 24 m² or 60 m³ to a perfect humidity level, free them of pollutants such as pollen, animal hair, dust and allergens as well as unpleasant odours and aromatise these rooms with health-activating fragrance oils.
Breathe healthier air and recharge your batteries for 16 hours with just one water filling
As simple as effective! Ultrasound turns the tap water filled into the 4.2-litre water tank into a refreshing spray mist, which is distributed in the room by the mist nozzle. Three adjustable atomisation levels (max. 250 ml/h) permit the continuous humidification of up to 16 hours. Once the water in the water tank is used up, the humidifier switches off automatically.
With this strong atomisation performance, the design humidifiers B 3 E and B 4 E are recommended to be used all year long as room air improvers in your private living environment, in offices, medical practices, therapy facilities, daycare centres and other comparable environments.
Clean air thanks to the carbon air filter and UV lamp
Whilst the room air is humidified, the integrated carbon filter cleans it from dust, pollen, animal hair, allergens and unpleasant odours. Moreover, an anti-bacterial UV lamp in the device interior effectively prevents the formation of biofilm in the water tank.
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 3 E / B 4 E is equipped with a removable scented oil diffuser for the additional aromatisation 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 3 E / B 4 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.
Breathe healthier, increased well-being, an improved quality of life
We spend a lot of time in closed rooms – at the workplace, in school, in university and at home with our families. In all these situations, the air quality and therefore also the air we permanently inhale is often everything but ideal. In particular in cold wintertime, heated air literally dries out the room air. To make matters worse, due to the cool outdoor temperatures we open the windows more rarely to let some air in, and pathogens and pollutants can spread unhindered in the room. This causes constant stress to our body and immune system, which is reflected by reduced well-being up to the point of us getting ill.
Let’s put an end to unhealthy room air!
The multiple-effect air improvement of the B 3 E and B 4 E will indulge you with a more healthy living and working climate – and without causing any considerable costs or annoying noises.
Clean room air with a perfect humidity level – on request with aroma fragrances
By adding essential oils, you can create you very own oasis of well-being. The right aromas increase your ability to concentrate at the workplace or make you get into your after-work mood at home in an even more relaxed way. Discover the variety of scents to create the right atmosphere for each occasion.
Energy-saving operation with timer function
With a power consumption of only 24 watts the comfort humidifiers B 3 E and B 4 E (at an average operating time of 8 hours per day) only consume electricity of approx. 20 € per year. A comparatively low amount for 365 days of additional well-being and health. The operating expenses can be reduced even further by the practical timer function to switch off the device fully automatically after a time that can be preselected (2 to 12 hours).
Incredibly low-noise room air improvement
You’ll have to listen very carefully to even perceive the sound of the comfort humidifier, which is as quiet as a whisper, in our everyday life. With a sound pressure level of just 38 dB(A) (at a distance of 1 metre), the B 3 E and B 4 E is only marginally louder than your own breathing sound. For comparison: Standard office printers work with a sound pressure level of approx. 50 db(A). The living space-friendly humidifier can therefore also be used in the noise-sensitive bedroom, in the children's room, or for working from home.
The comfort humidifiers B 3 E and B 4 E indulge you with healthier room air on 365 days of the year and additionally boost your immune system!

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.
