The majority of the day we spend indoors, which can hurt us especially in winter. Our skin may dry out, as can be seen on dry and cracked hands, especially at the knuckles, our eyes may start to tears and our voice may scratch. To reduce or even eliminate these annoying symptoms, KlimaLex give advice so you can enjoy a good and healthy indoor climate.
The optimum humidity for our health is 40 to 60 percent, in inhabited rooms, including bedrooms, at 45 to 55 percent. In many households and offices, however, according to hygrometer in winter, less than 30 percent prevail, because airing does not help much in the dry and cold outside air. As a result, the once-healthy plants let their leaves hang, the beautiful wooden floor suddenly creaks and the mucous membranes of the respiratory tract dry out, causing colds.

The damages of low humidity

Various materials, such as paper, fabrics, wool and cotton, tobacco, wood, furniture and carpets are impaired in their function at low humidity. Even plants, animals and even humans are deprived of water at low humidity. Damage, costs and physical ailments can arise here. Low humidity, among other things, also promotes static electricity, which can be detrimental in some industrial and business environments. With humidified air in the room the tendency to painful discharges by electrostatic charge is clearly smaller. Humidifiers operate in homes and businesses around the world to release moisture into the air, improving quality, performance, and profitability, thereby improving the work environment and well-being.
In addition, our airway self-cleaning function in dry air is compromised to be more susceptible to respiratory infections and diseases. Dry room air swirls, thanks to the thermals on the radiators more dust through the rooms and thus promotes the development of dust. Using a humidifier helps bind the dust to make it fall harder and faster to the ground. Thus, negative effects can be prevented by means of artificial humidification.
If you are not sure how dry the air in your rooms is, we recommend the humidistats we offer.

But why is the air so dry in winter? Cold air can absorb much less moisture than warm air. When the outside temperature is 0 ° C at freezing point, one cubic meter of air can only consume 4.8 grams of water. At 20 ° C, the air has a nearly fourfold capacity of 17.3 grams per cubic meter. The relative humidity (RH) is the ratio of the amount of moisture present in the air at a certain temperature to the maximum moisture absorbable by the air at that temperature (saturation amount). So the relative humidity is never constant, but depends on the season or heating habits, for example.
For example, if the relative humidity in the 20 ° C air is 50%, then this air per cubic meter contains 8.65 grams of water, since the saturation amount of the air at that temperature is 17.3 g / m³ (double the amount).
If exactly this air with its moisture content is cooled to about 10 ° C, the relative humidity is almost 100%. In the case of a more drastic cooling, there is consequently a surplus of water which dissipates in the form of condensation in the room (fogged windows, for example). If the water condenses on cool surfaces, it can cause unsightly damage.
When parquet comes into contact with condensation, this causes undesirable changes in the shape of springs. Adhesiveness can be removed on cold adhesive surfaces. The ideal indoor air temperature for laying floor coverings should be around 18 ° C, while the temperature of the subfloor should not be lower than around 15 ° C. When gluing with dispersion adhesives, the relative humidity should not exceed 75 percent.

Are there household methods to increase the humidity?

Indoor plants evaporate moisture over the leaves, but this is too low to contribute significantly to the humidification. Especially in the bedroom not too many plants are recommended, as they also operate at night photosynthesis, which leads without light supply that the plant absorbs oxygen and releases carbon. A cause of bad air.
The use of radiator evaporators is not recommended, as it heats the water to 30 - 40 ° C and this temperature range is ideal for the growth and multiplication of bacteria.
A similar bacterial focus is Zimmerbrunnen because they also formed in tests extremely many bacteria.
Evaporators heat the water to almost 100 ° C with a heating coil built into the unit. So there is a strong evaporation without strong air movement. These vaporizers are cheap to buy and almost sterile due to the heat. However, if the heating element does not properly heat up the water due to material fatigue, the warm water is also an optimal breeding ground for bacteria. Hot steam is a serious safety hazard due to scalding, especially for babies, toddlers and pets. The power consumption is also up to twenty times higher than other humidification techniques. In addition, the method of evaporation is inefficient because the water vapor without fan power can not spread throughout the room.
Evaporators also have a bactericidal effect when handled properly and functionally. Gentle humidification is achieved by distributing the water to special mats (to increase the surface area), where the water simply evaporates. The evaporators are very low in their power consumption.


Nucleation in water has always been a topic of discussion for humidifiers. The most important is definitely a regular cleaning of the humidifier to maintain a hygienic climate. It goes without saying that a humidifier that has not been cleaned for months, or the use of the same filter mats and decalcifying cartridges for years, is a magnet for the accumulation of bacteria. It would be the same if you do not clean your bathroom or toilet regularly. The moist environment provides an ideal breeding ground for all sorts of bacteria and viruses.
Tipp from KlimaLex: Clean your humidifier weekly so that neither sediment nor bacteria or germs have a chance! With regular use of the device, the cleaning is also much easier and faster to perform.

Health at work

Many workers have significant complaints of dry indoor air, especially when working on the computer. For example, symptoms include a dry mouth and throat, as well as electrical shock caused by static energy. If the central heating runs in winter, the problem increases. Many suffer from runny nose, colds, flu, drowsiness, headaches, and general laxity. Once the relative humidity drops below 50 percent, which is often the case, artificial air humidification with a Klimalex humidifier is appropriate.

Recommended room climate

The indoor climate is determined by various factors (temperature, humidity, air quality and air movement). A recommendable room temperature is 21 to 22 ° Celsius and may be no more than 26 ° Celsius in summer. The humidity in the room should be 45 - 55 percent. Especially in the bedroom, these values ​​are important to promote a restful sleep. Windows should be able to be opened and have a sunshade device, avoiding drafts, for example due to improperly controlled air conditioning, the cooling fan of equipment or leaking windows. Work equipment, such as computers, must not lead to increased heat load and air conditioners should be individually adjustable in the workplace. Calculator, screens, servers and printers but heat, can lead to electrostatic charge and reduce the humidity in the room.

Further possible uses for humidifiers

In public buildings to keep you healthy. Large crowds contribute to variations in humidity and temperature, which is why it is important to maintain the ideal indoor climate with the right amount of humidity. The artificial humidification reduces the susceptibility to diseases and increases the resilience and well-being. Otherwise, dry heating air leads to dry mucous membranes, which prevents bacteria and viruses from being caught, which increases the risk of cold and infection. Too much air will make you tired and give you a feeling of drowsiness. With optimal humidification you can effectively counteract brittle lips, a stuffy nose, scratching the throat and burning eyes.
Protect yourself and your environment with the right humidity and improve your overall well-being.

When printing, paper or packaging, to maintain quality. Electrostatic charge and misprints are avoided as the drying and consequent shrinkage from the paper. The ideal humidity ensures better accuracy of fit, less dust, less waste and a more pleasant room climate. At the same time paper warpage, electrostatics or slowed down production are avoided. In order to maintain the quality and for processing, every hygroscopic (moisture-attracting) material requires optimum fabric moisture. The harmonization of indoor air is also very important in the paper industry, otherwise paper processing is not possible.

In the Textile industry to reduce yarn breaks, material flow problems and quality losses. Thanks to the avoidance of electrostatic charge, there is no danger of fire due to electrostatic charge. Yarns must be in balance with the relative humidity of the ambient air, as yarns that are too low in moisture content are much more delicate, brittle, thinner, and less elastic, which can lead to static build-up, poor quality, and lower production through frictional processing.
It is proven that increasing the relative humidity of air from 53 percent to 68 percent reduces the number of warp breaks by 31 percent. A further reduction in warp breakage by 12.5 percent results in a further increase in moisture to 78 percent.
Textiles that have an ideal moisture content are much easier to handle and are more uniform. The reduction of micro-dust also ensures a more pleasant working environment.

In the leather industry, so that the leather does not lose its shape and for easier splitting of the leather. Again, electrostatic charging is avoided by optimal humidity. If there is enough humidity, the elasticity and flexibility of the leather will remain, which prevents cracks during stretching. The production of leather requires several steps and is expensive. A proper storage with good humidification is crucial to maintain the leather in its shape, size and also in its suppleness. Leather should be stored in cool and airy rooms at a constant temperature and relative humidity of between 50 - 75 percent to avoid brittleness or hardening of the leather.

In the wood industry, including carpentry, to avoid cracks. Advantages of air humidification are that there is no warping or deformation of the wood and also less infestation of woodworms. Variations in the quality of the material are associated with a high cost for a wood processor, because many manufacturing processes are not feasible without adequate humidification. If the air is too dry, there are problems especially when processing organic materials such as wood.
Besonders während der Heizperiode ist es nicht unüblich, dass die Luftfeuchte auf Werte unter 40 Prozent sinkt. Bei unzureichender Luftbefeuchtung können Schäden wie das Quellen, das Reißen, das Verformen oder das Verziehen des Holzes auftreten. Möbel, Fenster sowie Türen können sich bei zu niedriger Luftfeuchtigkeit verziehen und Holzwürmer und andere Insekten können das Holz befallen. Durch Luftbefeuchtung lassen sich Kosten aufgrund von Schäden verhindern.

For electrical engineering and EDP for a dust-free environment. The accumulation of dust is prevented by the humidification by the dust falls heavier and faster to the ground. There is no static charge due to at least 45 percent relative humidity, as voltage differences are reduced and there is also less production waste.

In the tobacco industry against shrinkage, brittleness and flocculation of tobacco leaves. With ideal humidity, there is no crevice formation and less production difficulties because tobacco leaves are highly hygroscopic, which means that the leaves attract water and absorb water vapor from the air during prolonged storage. Optimal humidity is also essential for cigarette paper, as changes in humidity alter the dimensions of the paper roll, which can lead to production difficulties such as feeding errors in the machinesAll diese Probleme können mit einer konstant gehaltenen Luftfeuchtigkeit vermieden werden.

In the food industry to preserve the taste. With ideal humidity, there is almost no weight loss, the ripening process can be accelerated and a guarantee of durability is possible. As the quality requirements of customers increase steadily, it is essential for food to ensure the quality of a certain moisture content. In addition, it is very important that this quality is maintained from the manufacture through any intermediate steps to the end customer. Regulated air humidification is indispensable in the trade, for example at cheese, meat or sausage counters, as optimal humidification preserves the taste, shelf life and appetizing appearance. Even food and other semi-finished and finished products are hygroscopic, meaning that they are in exchange with indoor humidity.

In hospitals and operating theaters for smooth treatment. In hospitals, artificial humidification of the room air to comply with the required indoor climate is absolutely necessary. In particular, attention must be paid to the required safety with regard to the specified compliance with clean air quality. Poor air quality has serious effects, such as tiredness, lack of concentration, headache or eye burning. These can have a negative impact on the well-being and health of employees and patients. Dried out mucous membranes, due to respiratory irritation, can not properly defend bacteria that are in the air. These bacteria can then trigger inflammation.
The expensive electrical equipment in operating theaters can be sensitive to, for example, the generation of electric shocks, to dry air. Especially in connection with flammable anesthetics in the form of gas, the risk of electrostatic charge must be considered.
Optimum humidity is important, especially in maternity and nursing intensive care units, as infants and babies are very sensitive to dry air.

In Animal Breeding to maintain the health of the animals. Optimal humidity is essential to ensure economical and productive animal rearing. With the help of artificial humidification, the evaporation of water, among other things, lowers the temperature in the barn, which noticeably increases the well-being of the animals. This avoids aggressive behavior among the animals and significantly reduces energy costs. The humidified air also binds dust particles in the air and thus relieves the respiratory organs of the animals.

In exhibitions, museums and art galleries for consistency of value. Too much air in museums, churches and even private collections causes costly damage as the indoor air draws water from materials such as paintings, wood or sculptures. Lack of humidity can also cause yellowing and the bursting of color. A constant moisture balance is also important to avoid irreversible formation of cracks on exhibits and to preserve the luminosity of colors.

In clean room technology or in cleanroom laboratories, so that complex processes and investigations can be carried out. The ideal humidity can provide a higher production speed, enable the realization of high-tech products and reduce rejects and production losses. Dust from dust may render the product or people involved useless. KlimaLex air humidifier can help reduce dust accumulation.
