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.
Vaporiser
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.
Evaporator
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.

4 tips on buying the right humidifier
Measure the humidity
You can measure the relative humidity in a room using a hygrometer. For measurement to be accurate, it is important for the hygrometer to be positioned correctly: set up the hygrometer on a raised surface in the middle of the room, away from windows and doors. Wait a few minutes for the sensor to adjust to the room temperature.
Determine the room size
It is important to know how big the room in which you are going to be using the humidifier is. If the doors to other rooms are open, the area of those rooms must also be included. Room area is calculated by multiplying the length and width of the room (e.g. 5 x 6 metres = 30 m2). To get the room volume, you multiply the room area by the ceiling height (30 m2 x 2.5 metres = 75 m3).
The room size should be doubled for minimum energy houses with controlled ventilation. Choose a humidifier that is recommended for at least your desired room size/area.
Find out how hard your water is
Water hardness is a measure of the quantity of minerals in water. The higher the percentage of those minerals, the harder the water. The device you need will depend on the hardness of your water. If you don’t know the hardness of your mains water, you can ask your local water supplier or ask us to send you a test strip.
Choose the right type of system
There are 4 different types of humidifier: evaporator, ultrasonic nebuliser, vaporiser and air washer.
- Soft water (0 ° - 4 °dH) = all systems
- Water of medium hardness (5 ° - 13 °dH) = all humidification technologies can be recommended though in the case of ultrasonic nebulisers, the anticalc cartridge should be used
- Hard water (from 14 °dH) = evaporators and air washers with an anticalc cartridge are recommended
