HUMIDIFIER PURCHASING GUIDE
HOW YOU CAN FIND THE RIGHT HUMIDIFIER AND 10 REASONS FOR HAVING A HUMIDIFIER
Buying a humidifier is not so easy. There are many different criteria that can influence the decision to purchase. These criteria are explained in the following text and 10 reasons are given for why it makes sense to use a humidifier to improve the indoor climate.
The room size is key when choosing the right humidifier. The rule here is that the volume is to be measured and not the area (area in m2 x room height). Generally speaking, manufacturers work on the basis of a room height of 2.5 metres for their recommendation of the room size.
Consider where you would like to use your humidifier (e.g. living room, children's room or bedroom). Other criteria are important depending on the room for which you need the humidifier. Our online decision making aid can be found here: Product advisor
Different technical features are more or less important depending on the purpose for which the humidifier is used. For example, a brightly illuminated LED display is not something you would want in the bedroom. This is why the LED should be dimmable or the appliance should even have a night mode. In a small room it is important that over-humidification does not occur. Therefore choose a humidifier with the self-regulating evaporation principle. Vaporisers and ultrasonic nebuliser need a hygrostat.
In humidifying a room we differentiate between ultrasonic humidifiers, nebulisers, evaporators, vaporisers and air washers. Each system has its advantages and disadvantages. This is why you should allow yourself enough time when making the decision. In this section you can find an overview of all the systems.
Water can be divided into four different levels of water hardness (°dH = german degree of water hardness):
Soft (as of 4 °dH)
Moderately hard (as of 7 °dH)
Rather hard (as of 14 °dH)
Very hard (as of 21 °dH)
Vaporisers and ultrasonic nebulisers are not suitable for very hard (calcareous) water. This also applies if water from a decalcifying system is used.
With regard to water from decalcifying systems, salt is added to the water to reduce limescale (ion exchanger). Salt alters the boiling point. This leads to overheating and to deformation of the vaporiser. With regard to ultrasonic nebulisers, the salt added is finely atomised and results in a disruptive white deposit.
We recommend using an evaporator or air washer for water from a decalcifying system and for hard water.
Maintenance requirements are higher for hard water than for soft water as decalcification is required more often. A thorough cleaning is indeed imperative in all cases to prevent the growth of germs and bacteria. Purchasing an appliance that can be cleaned without any difficulty is therefore recommended. Accessories, such as a decalcifier cartridge for the ultrasonic nebuliser or a filter mat for the evaporator, should be taken into account when calculating the purchase price as they have to be replaced from time to time.
When the air is very dry, you switch on the humidifier constantly where possible. Nevertheless, you can still control energy consumption: Whether the appliance has a hygrostat or not is crucial. The hygrostat can be used to set the desired humidity. The humidifier shuts off as soon as this is reached. The different systems also differ in terms of their respective power consumption: a vaporiser consumes lots of power whereas an evaporator requires little energy.
If a person responds very sensitively to sound, we would advise against purchasing an ultrasonic nebuliser or vaporiser. With regard to the ultrasonic nebuliser, the vibration of the membrane creates what is often regarded as an unpleasant quiet humming noise. With regard to the vaporiser, the "bubbling" of the boiling water may be considered annoying. Our evaporators make the least amount of noise.
10 REASONS TO PURCHASE A HUMIDIFIER
Dry air primarily develops in winter when significant heating takes place and room humidity often drops below 30 %. Opening the window does not help, and it even has the opposite effect. The precise explanation of relative humidity can be found here
Our mucous membranes need a certain amount of moisture in order to not become inflamed during winter. If the air is too dry, this puts stress on our entire immune system in the long term.
Dry air can be a cause of restless sleep as the whole body is under greater strain than it would be were the humidity optimal (40 – 60 %). It is mainly babies and small children who respond very sensitively in this regard.
Reduced allergy risk
Pollen and dust bind more easily in moist air, become heavy, and fall to the ground. This prevents them spreading and so fewer irritations arise.
No nose bleeds
Nasal mucous membranes suffer in dry air and are more susceptible to nose bleeds.
No dry eyes
In winter, we often wake up with itchy or burning eyes, or eyes that are stuck shut. This is a clear sign of dry air. A humidifier quickly and efficiently solves this problem.
Our skin requires a good basic level of moisture. In addition to the appropriate cosmetic products, a healthy humidity is indispensable to keeping the skin firm and healthy.
Gentle ambience for wooden furniture and flooring
If the air is too dry, the moisture is drawn from solid materials such as furniture, walls and flooring first of all. As time goes by, wooden furniture and equipment parts become cracked and brittle. The right humidity can counteract this. Retailers of wooden flooring often recommend a certain humidity (between 40 – 60 %) as otherwise the quality of the floor can no longer be guaranteed.
Less dust and static charge
The moist air ensures that less static charge occurs. This means less static in hair and from clothing.
Healthy house plants
The soil is a good reservoir for moisture. If the air is too dry, then moisture is also taken from the soil of the house plants from time to time. This leads to drying up occurring faster.
Instruments are not put out of tune
Instruments such as pianos, guitars, violins and other stringed instruments do not go out of tune so quickly if kept at an appropriate humidity.
