Ultrasonic humidifier B 5 E

Ultrasound technology for a pleasant room climate and air quality improvement

A healthy life with clean breathing air! The Trotec 2-in-1 humidifier B 5 E ensures an optimally humidified room climate in your private living quarters. Furthermore, the integrated ionizer eliminates pathogenic viruses, bacteria, pollen and house dust. Finally you can breathe freely without any health worries! You can prevent colds, irritated eyes and dry skin by humidifying the room air to an ideal level.

Would you have known? We spend the major part of our lives indoors and breathe air that is contaminated with house dust, bacteria and other irritants. No trace of fresh breathing air there! Air contaminated with irritants promotes coughs and sneezes as well as the transmission of pathogenic bacteria. Children and allergy sufferers are particularly prone to this.

Just breathe! The humidifier B 5 E uses ultrasound to turn the tap water from the storage container into an atomized spray and distributes this refreshing gush of ultrafine mist droplets in the room via the mist nozzle that is freely rotatable by 360°. Three adjustable atomization levels permit the continuous humidification of up to 13 hours. With its high atomization performance of up to 7.2 litres per day the ultrasonic humidifier B 5 E is ideally suited for room sizes between 30 m² and 75 m³.

Be it pets, people or plants – all perceive the improved air quality as agreeable. One of the benefits is the reduced risk of catching a cold. You house plants will surely be grateful as well for just a little more moisture.

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.

On the agenda: healthy breathing air

A suitable operating mode for any application

The intelligent B 5 E comes with a variety of operating modes. Parents will appreciate the baby mode. The room humidity is regulated to a level optimally suitable for small children. During automatic operation the B 5 E takes over control and generates the perfect room climate fully automatically. Anyone opposed to handing over the reins can easily set the desired target humidity value by hand. The versatility of the B 5 E is completed by a freely programmable timer for automatic switch-off and a night mode to promote a healthy good night's sleep.

In spite of this functional range it is conceivably easy to start up this ultrasonic humidifier. All settings can easily be made via the control panel at the front of the B 5 E. In everyday operation the B 5 E can impress with low maintenance requirements. In case of an empty water tank the device switches off automatically. If the humidifier needs to be cleaned or maintained, it is disassembled in just a few steps.

The optional on-demand illumination of the water tank renders this modern nebulizer a genuine eyecatcher that harmoniously integrates into any area of life. 

Reduction of viruses and pollutants thanks to an optimum humidity level in the room air
The mucous membranes must be well moistened
The optimum humidity level kills viruses

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 percent, 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.

Tested for safety

Benefit from the Trotec brand quality guaranteeing high value, safety and functionality. Via the registered GS mark the inspection authority Intertek certifies that, if used foreseeably and as intended, the device does not pose a risk to the health and safety of the user.
