Trotec evaporation humidifiers

Our product range offers a wide choice of electric humidifiers with various functions and modern designs. Humidification From the compact starter model to the versions also suited for larger rooms or which permit the addition of scented oil to sweeten the air – we have the right evaporation humidifier for every requirement.

The ideal humidity level

Especially during the winter the air in interior spaces is often too dry. This is attributable to several factors: for one thing, the cold air admitted to the room from outside when airing it out has a lower moisture absorption capacity. Then there is the matter of heating – often turned up to the maximum during the winter. The heater further heats the already dry air and sets it in motion – along with the irritating house dust. 

Should the humidity level fall below 30 per cent, this can certainly affect our health.

Especially allergy sufferers and asthmatics often struggle with the consequences of excessively dry room air. According to the German Federal Environmental Agency the ideal humidity level ranges between 40 and 60 per cent. Studies also suggest that this is the range wherein most people feel particularly comfortable. Allergy sufferers and asthmatics feel best at the top of this range.

However, the humidity should not exceed 60 per cent for otherwise the moisture could start to precipitate on walls and furniture possibly resulting in mould growth, especially in the wintertime.

Too humid or too dry air at home is not only harmful to us; our favourite belongings such as antiques or books can also suffer damage.

Especially dry air often leads to eye irritations, frequent colds, dry coughing or irritated mucous membranes. 

An evaporation humidifier can be used to take the room air to an optimum level allowing you to breathe easy again. What is the optimum room humidity level and how does an electrical evaporation humidifier work? 

Cold evaporation principle for humidifiers

Many humidifiers heat the contained water, thus inadvertently creating the ideal breeding ground for bacteria. Not in the case of the cold evaporation principle we employ for our evaporation humidifiers. The water remains cold and gives bacteria no additional reason to grow.

We differentiate between two options: an evaporator with honeycomb filter and an evaporator with a revolving humidification drum. The honeycomb filter makes use of a special honeycomb structure that draws the air into the humidified filter where it is “charged” with moisture.

In case of the humidifier with revolving humidification drum, though, the air is sucked in by a fan and then led through a rotating drum with especially humidified filter fleece.

As a result the air is not just enriched to the ideal humidity level, but also purified.

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.

An agreeable room climate ensured by the humidifiers from Trotec

Be it humidifier, evaporator or air washer – Trotec devices allow you to breathe freely after only a short period of use. Both models optimally regulate the humidity level, thus ensuring a healthier room climate and protecting your furniture, books, paintings or antiques from damage caused by too dry or too humid air.
