Give viruses no chance: Humidification in daycare centres and schools

Especially children are often afflicted with health problems caused by dry air. An ideal room climate can be ensured using Trotec humidifiers and air washers.

Hardly anything affects our health as much as the air we breathe every day. This is particularly true for our children who attend schools and daycare facilities every day. Dry room air makes the little ones more susceptible to diseases and substantially lessens the power of concentration, consequently it is important to ensure the best hygienic conditions and fresh air for them. These institutions cannot always see to a regular ventilation, hence support by modern-day technology is all the more important. When using high-performance humidifiers and effective air washers, which Trotec has on offer, the room air is enriched with moisture and filtered at the same time. For the best possible well-being and the health of our children.

Five times a week we send our kids to daycare centres or schools. They spend many hours there, often enough the entire day. Beside the educational programme parents are also very exacting about healthy meals and the best possible hygienic conditions. And with good reason! After all the children are supposed to feel comfortable there to encourage an advantageous development. Therefore these institutions carry a special responsibility – also with regard to the indoor climate in group rooms or classrooms. Already in early autumn heaters are put into operation to protect from the cold. But this simultaneously creates dry room air which does more harm than you would think.

Dry air is bad for your health

It's a commonly known problem: One kid caught a cold and attends school or daycare nonetheless and already the disease spreads with lightning speed amongst the friends. One reason for the quick contagion are too low humidity values within the facility. For flu viruses are disproportionately more active in dry air. At the same time the children's mucous membranes dry out, which makes them more susceptible to viruses and germs. As preventive action we recommend better climate conditions, e.g. an adequate indoor humidity level. It is hard to achieve this only by ventilating the rooms, because it takes a lot of effort to look after all kids while the windows are open. The use of modern technology might produce relief: The humidifiers and air washers from Trotec not only ensure optimum humidity values in daycare centres and schools. They also filter the air. Enough reason to take a deep breath.

The best climate to further one's ability to concentrate

Further facts should illustrate just how important it is to configure the air quality, and especially the humidity level, in daycare centres and schools to an optimum value. The children's motivation and power of concentration clearly decrease the drier the air. Dry air interferes with the absorption and transport of oxygen in the blood. The detrimental effects of dust particles and microorganisms are also intensified. They are lacking the binding element of water vapour in the air, as a result more ends up in the respiratory tract.

Trotec offers the solution: Humidifiers against pathogens

We have to accept that pathogenic viruses and bacteria restrict our daily life, but we do not have to accept them spreading through the room air! The Trotec humidifiers – e.g. the B 400 and the B 500 – perform valuable services. Airborne transmitted infections are a serious problem, especially in daycare centres, kindergartens and schools. Children in particular will not keep sufficient distance from each other while they're playing. Besides, think about the health risks that child care workers, caretakers and teachers are exposed.

The evaporation humidifiers of the Trotec B series are controlled via hygrostat and provide optimum humidity conditions for any room size. Choose from the B 24 E, B 25 E, B 250, B 300, B 400 and B 500 (radio-controlled) model – you will surely find the suitable device for your individual requirements.

As a matter of course, you can also use the Trotec air washers of the AW-S series. Whether an evaporation humidifier or an air washer offers the best solution for you will finally depend on the room size and the required humidification performance.

The efficiency of humidifiers against bacteria, viruses etc.

The picture is great to see that in a hallway with 40 to 60 percent relative humidity, the number of pathogens such as viruses and bacteria is nearly equal to zero. Why is that? If the room air's relative humidity is less than 40 percent, secretions from coughing and sneezing that are contaminated with viruses such as the coronavirus Sars-CoV-2, flu viruses or bacteria will dry. This may sound positive at first, but the opposite is true: They shrink to a size of approximately 0.5 µm, forming a protective layer around the aerosols. This maximises the survivability of pathogenic germs from the inside and also enhances the droplets to float in optimum conditions. If somebody coughs or sneezes in a room that is too dry, viruses and bacteria will survive up to 41 hours while keeping their infective effect.

An extra portion of health for inhalation

The mobile evaporation humidifiers from Trotec are exemplary for an effective humidification and filtration of the air. The models are compact and characterized by low-noise operation, lest they disturb students during tests. The humidifiers can be connected quickly and easily in a class- or group room and started at the touch of a button. The hygrostat-controlled humidifier is automatically regulated once the desired humidity value has been set initially. All Trotec humidifier models operate based on the reliable evaporation principle. Lime deposits and the formation of condensation are ruled out the same as an excessive humidification of the room air. You are limited to the optimum range between 40 % and 60 %. Pollutants in the water (e.g. germs) remain in the water tank and filter are not passed on to the room air. This ensures hygienic operation with the bacteria output reduced by 99 % as compared to ultrasonic humidifiers. Trotec always provides the right model suitable for small- and large-scale applications. In smaller rooms of up to 24 m² the designer humidifier B 25 E, perfect in form and function, prevents our little ones' airways and noses from drying out. At times an agreeable room scent through perfumed oil is also welcome. The compact B 200 eco for instance emits up to 43 litres of water per day or even more and can shine with an ideal value-for-money ratio. Both powerful and reliable in the humidification of larger rooms are the B 400 and the B 500 radio, emitting impressive 60 litres to the ambient air and offering many modern extra features.

How an "air wash" works

Suitable for smaller areas such as the adjoining room of a daycare group, where the young 'uns are put down for an afternoon nap, are the compact and stylish Trotec air washers of the AW-S series. They unite an appealing design and ideal air purification. Both the AW 10 S and the AW 20 S suck in the room air and guide it past rotating humidifier disks; there the air is charged with moisture. During this process dirt particles such as pollen, hair and dust cling to the disk and are bonded in the collection container. Furthermore, depending on the operating mode, the AW 20 S provides an additional thorough HEPA filtration of the humidified air.
