Humidifiers increase the relative humidity indoors by humidifying excessively dry indoor air actively (vaporisers and nebulisers) or passively (evaporators and air washers). Say goodbye to air that is too dry and the effects that this can have on your health – with a humidifier from Stadler Form.

The Problem

Dry air, dry mucous membranes

If the relative humidity drops below 40%, the air becomes too dry. This can lead to symptoms such as headaches, burning eyes, dry and inflamed mucous membranes, dry skin, an unpleasant scratchy feeling in the throat, poor sleep and increased susceptibility to colds or flu.

Symptoms caused by dry air

  • Burning eyes
  • Dry skin
  • Inflamed mucous membranes
  • Increased risk of flu
  • Restless sleep
  • Poor concentration
  • Feeling unwell

The Cause

Cold season & central heating systems

The air indoors primarily becomes dry in winter due to the cold air outside being able to absorb a lot less humidity than the warmer air in spring and summer. In the case of passive or minimum energy houses, central heating systems and ventilation systems only add to the problem. Humidifiers from Stadler Form create an optimal indoor climate, even in the cold winter months.

The Solution

Humidifiers for healthy air

If the hygrometer permanently measures a relative humidity of less than 40%, only a humidifier will help. There are different designs, but the function is always the same: Increase the relative humidity of the room air by bringing additional moisture (water) into the air. Stadler Form has the right humidifier for every need.


The water is brought to boiling point in the device using a method similar to the one applied in a kettle, for example. Boiling the water produces hot, germ-free water vapour which is emitted by the device directly into the room. Vaporiser systems are particularly suitable for allergy sufferers. It is important for limescale to be removed regularly from vaporisers. We advise against using hard water or water from water softeners in vaporisers.

Ultrasonic nebuliser

This type of humidification system turns water into mist. An oscillating ultrasonic membrane in the nebuliser atomises the water, turning it into tiny droplets. A built-in fan in the device transports them into the air as mist which humidifies the room air. In principle, the mist emitted by the device is cold because the water inside it is also cold. This makes nebuliser systems suitable for nurseries. With this system, the process of humidification is made visible due to the mist, which is why these devices are also known as atomisers. It is particularly important for nebulisers to be cleaned and descaled regularly. Nebulisers are not suitable for use with hard water or water from a water softener.


The way that an evaporator works is based on the natural principle of evaporation. The humidifier filters inside the device suck up water. The indoor air is sucked in by an integrated fan which guides it through the moist humidifier filters. In the process, the air absorbs the humidity required. As it flows through, the air absorbs tiny water droplets and it is then blown out into the indoor air along with the moisture. The evaporator system has two main advantages. Firstly, evaporators are very quiet, making them the ideal choice for quiet rooms such as bedrooms or offices, for example. Secondly, overhumidification is not possible with this system as the air is only enriched with as much humidity as it needs and is able to absorb based on the current temperature. With this system, the filters need to be replaced regularly.

Air washer

This system is a combination of humidifier and air purifier. The principle of humidification belongs to the category of evaporator systems. The difference lies in the humidification medium used: air washers use permanently reusable plastic discs while evaporators have filters which need to be replaced regularly. Air washers are fitted with a set of discs specially designed to absorb humidity and remove particles from the air. The discs which are known as humidification discs or evaporator discs rotate in the water. A fan sucks in the dry indoor air which is guided across the rotating wet discs. Pollutants from the air such as pollen, dust or hair are deposited on the discs in the process. The set of discs continues to rotate and the particles are washed off in the water. The purified moisture still present on the clean part of the disc set is emitted into the air. With this technique, the air is not only humidified but also cleaned to remove pollutants, making air washers ideal for allergy sufferers. Regular cleaning is important in order to rinse out the water tank and remove the impurities washed from the air.
