What is a humidifier?
While a dehumidifier removes moisture from the room air, a humidifier provides the exact opposite, namely a higher humidity in the room. The devices are called room humidifiers, air scrubbers, steam humidifiers or air humidifiers by the manufacturers. They are devices that enrich the room air with moisture by releasing a fine, moist spray into the environment. There are two types of humidifiers:
1. Electric humidifiers with a water tank in different sizes 2. Room humidifier with a fixed connection to the water pipe
The room humidifiers can often be combined with a central ventilation system. The more familiar type of humidifiers are the electrical devices that require only a normal power outlet for startup. Most portable humidifiers have water tanks ranging in size from a few milliliters to several liters. Depending on the manufacturer's specifications, they can be used for different room sizes.
When is a humidifier useful?
Many people struggle with dry or tired eyes, sleep poorly, or suffer frequent headaches. In addition to many other reasons that can lead to these symptoms, indoor air that is too dry can also be the cause of these complaints. In winter, when the heating is at its highest level, the indoor climate is very dry. As a rule, the climate in this heating period is too dry, after all, the heat from the heating can dry out the air. Common consequences are:
– Tension due to dry skin – Dry and often irritated mucous membranes of the nose and eyes – Dust flying around, carrying germs with it
The problems are unpleasant, but can be combated with a humidifier. But what is an optimal indoor climate? Should it not be different in different rooms? The statement is correct, but an optimal room climate is assessed differently by each person. One likes it a little more humid, the other prefers drier air. The following table gives a good estimate of what a good indoor climate with a room humidifier should look like:
If the air in the room is too dry, furniture, musical instruments or wooden floors can also be damaged. Humidifiers are often used even in the medical and care sectors. They are used there to humidify the air breathed so that the mucous membranes of artificially ventilated patients do not suffer damage from too much dryness. Air purifiers can also lower the risk of infections with virus filters. How else can I increase the humidity of the air?
Who wants to do without the purchase of a humidifier, has other possibilities, in order to increase the air humidity in areas. The simplest method is to place a houseplant. With a leaf area of 6 square meters, a plant evaporates on average between one and 2 liters of water per day. Many plants not only humidify the air in the room, but also purify it. There are some plants that are particularly suitable for use as room humidifiers:
– Philodendron – Green lily – Dragon tree – Bromeliad – True aloe vera – Cyprus grass
as well as other plants. If you are not a plant lover, you can mimic the evaporation principle with a damp towel over the heater or a bowl of water on the window sill. The advantage of a humidifier including a hygrometer is that the desired humidity can be controlled specifically. This is not possible with the alternative methods mentioned above.
Overview of different types of humidifiers
In a humidifier, manufacturers distinguish between three types, which differ in terms of their technology – atomizing, evaporating or vaporizing. The three terms bring clarity to the confusion that many manufacturers cause among prospective buyers with sometimes unclear designations. Atomizing is also known as ultrasonic technology by many suppliers. We present all types of humidifiers in the following paragraphs:
1. Evaporators evaporate water passively. Do not actively spray it into the environment. These types of humidifiers operate in an energy-saving and efficient manner, but can normally humidify less air than evaporators. In an evaporator air. Water by means of rotating discs constantly mixed. This virtually washes the surrounding air, which is why such products are more commonly found under the name air scrubbers. Overhumidification of the room is impossible with an evaporator. They are passive humidifiers, which can usually be attached to the heating of the room.
These are the main advantages and disadvantages of air washers:
– Low power consumption – No risk of overhumidification – Without aerosols – Work efficiently
– Low strength – Room temperature is lowered – Water stands for a long time – Wet towel over the heater has similar effect
2. The vaporizer
An evaporator works as follows: A heating element heats small amounts of water over a long period of time, causing the vaporizer to regularly emit a warm water vapor. The advantage is that heating prevents germs from forming in the water, and the steam is much more hygienic and healthy than other methods of humidification. Evaporators usually have a strong power, thus consume more electricity than other atomizers or air washers, in addition, they are expensive compared to other types.
In addition, the water vapor is warm, which warms in winter, but does not provide cooling in summer. An evaporator often uses an electric heating element that functions like a regular electric stove top.
These are the main advantages and disadvantages of vaporizers:
– High output – Kills germs – Can be used with distilled water – Does not drop in temperature
– High power consumption – Expensive compared to other types – Intensive cleaning requ.
3. Humidifiers with ultrasonic technology – Atomizers
Many households opt for an ultrasonic unit when looking for a humidifier. The technology allows water to be nebulized into small water droplets, creating a cool vapor with the water molecules. Some devices have a heating function, which can produce a warm spray despite the ultrasound technology. Since the water is finely atomized, the devices are also known as atomizers. On almost all models the strength of the mist can be adjusted individually. They have a low energy consumption. Are easy to operate.
The only but relevant problem: ultrasonic vaporizers without heating function do not heat the water, which does not kill germs. Users must clean the unit regularly to avoid blowing countless viruses and a high concentration of bacteria into the air. Alternatives are built-in filters or special coatings that kill or filter out bacteria, respectively.
These are the main advantages and disadvantages of ultrasonic humidifiers:
– Low power consumption – Inexpensive – Controllable mist as a method – Humidifies quickly and widely
– May over-humidify – Temperature is lowered – Without heating function or alternative, no protection against germs and bacteria
Important purchase criteria for a humidifier
Depending on what requirements a user has for a humidifier, different models are recommended. They differ in terms of volume, room size to be humidified or maximum run time. Below is a brief overview of the most important purchase criteria:
Room size: Evaporators have the largest depth of all humidifiers, at about 40 centimeters. The space is needed to accommodate the boiling unit in the housing. Ultrasonic devices usually manage with a construction depth half as large. The size of the device in itself does not say anything about the size of the room for which a model is suitable. The corresponding information can usually be found on the package or in the operating instructions of a humidifier. It is usually expressed in square meters, in rare cases in cubic meters: most devices cover rooms between 20 and 40 square meters – aming normal ceiling height. Atomizers usually have the largest room coverage.
The water tank: Every humidifier has a water tank to humidify the room air – no matter what technology is used. The larger the tank, the longer a room can be supplied with mist under normal circumstances. On the other hand, more time is needed to refill the water tank. Cleaning a larger tank sometimes turns out to be more difficult than with a small model.
Performance: If the size and water tank volume of the selected humidifier fit, buyers should think about the performance of the device. Manufacturers specify a value for this in the unit milliliters per hour. The higher this value, the more air can be humidified in this period of time. Here it depends on which room at what time the humidifier is to be used and how dry the air is there.
Power consumption: Almost all humidifiers on the market have a sensor that switches the device off as soon as the water is completely consumed. This keeps the power consumption low. Evaporators get by with little energy. Atomizers need more power, but are more energy efficient than vaporizers and therefore lie in the middle in terms of power consumption. The ultrasonic function consumes less energy than the permanent heating of the water. Humidifiers with ultrasonic function usually consume less than 50 watts. Sometimes there are devices with a consumption of only 2 watts.
Volume: Humidifiers are initially quiet when first started up. This says little or nothing about how loud or quiet the devices work in continuous operation. Even small, monotonous noises can deprive people of sleep at night. Therefore, if you want to use a humidifier in the bedroom, you should look for a maximum noise emission of 40 decibels, preferably less.
Automatic shut-off function: Many humidifiers have an automatic shut-off function. When the desired room humidity or low water level is reached, the unit automatically shuts off. This ensures greater safety during use. Prevents damage.
Remote control: Some models have a separate remote control that can be used to turn the device on and off, select the intensity or set the timer. It is a nice extra feature that does not affect the performance of the humidifier. Operation by switch-on or rotary knob is only slightly more complicated.
LED lights: Numerous humidifiers have their own lighting device. In most cases, LEDs are built in. The LED lights shine continuously, can be switched off as desired, and either pulsate in a single color or have a color-changing function. Many users find the color-changing function pleasant, even though experts still disagree about the influence of the different colors on the human psyche.
Aroma additives: Some humidifiers are suitable for adding aromas to increase the feel-good factor. Suitable essential oils can also have health benefits. Allergy sufferers should be careful. Because one or the other fragrance experience can lead to unpleasant side effects in allergy sufferers can.
Special feature: a humidifier with hygrostat
Technically sophisticated models are able to analyze the air in the living room and regulate the humidification output according to the user's wishes. A so-called hygrostat, also known as a humidity meter, is used to measure the relative humidity, or RH, in enclosed spaces. It is determined with the help of an element of plastic fabric bands: If the percentage of humidity in the room increases, the fibers absorb moisture. This results in a measurable change in length. Some humidifiers are coupled with a hygrostat and will only operate when the humidity drops below a certain level.
What is the difference between a hygrostat and a hygrometer?? The term hygrometer is often used as a synonym to the hygrostat, but they are two different technical devices. A hygrometer is an instrument for measuring the humidity of the air. Inside it there is a humidity sensor that measures and names the relative humidity of the air. A hygrostat also has a sensor, but also acts as a switch. Therefore, a hygrostat is primarily found in devices such as humidifiers or dehumidifiers, in which it works as an automatically regulating system.
People feel comfortable when the humidity in a room is between 40 and 60 percent. With the exception of evaporators, all humidifiers can cause over-humidification of the air if a humidistat does not shut them down in time. Too humid room air can lead to health restrictions: People feel uncomfortable and start sweating. In addition, humid air over a long period of time leads to mold growth, as it is known from basements or attics. Molds are considered pathogens and can cause, among other things, allergies and asthma. So, special care should be taken, especially for people who are already asthmatics.
What are the dangers of humidification?
When using a humidifier, buyers always face two dangers:
– The distribution of germs in the room – The overhumidification of the room
As early as 2016, Stiftung Warentest reported that atomizers spread many germs coming from the water tank. Therefore, regular cleaning of the device is necessary. Evaporators are a safer solution from this point of view.
Unpleasant – legionella: Legionella are bacteria that multiply rapidly in water at around 20 degrees Celsius. Only a temperature of more than 60 degrees Celsius kills them off. They are usually harmless when drunk, but when inhaled they cause the so-called Legionnaires' disease in humans.
To eliminate the risk of overhumidifying a room, measuring the humidity with measuring devices is a mandatory part of using humidifiers. Because in case of permanent overhumidification, too much water accumulates on the walls and the windows. They inevitably start to mold.
Where to place a humidifier?
The most important criterion when looking for a suitable location for the humidifier is safety: if there are small children or animals in the household, it is essential to ensure that they cannot reach the device. Evaporators are particularly dangerous because they heat the water to the boiling point, i.e. they make it boil. There is a risk of scalding with hot steam and heated water in the water tank. In addition, a horizontal surface is necessary so that the humidifier can neither slip nor tip over.
In order for the humidified air to reach all areas of the room evenly, most manufacturers advise placing it in the middle of a room. Mostly, however, the device is then in the way. A dining table or a bedside table next to the bed is more suitable. In case of emergency, a shelf can be considered. When placing the device, it is necessary to keep enough distance from books and electrical appliances, otherwise the spray mist can damage them. Manufacturers recommend a minimum distance of one meter from all sensitive objects and from the head of the bed.
Select location with high air circulation: It is advisable to choose a location with higher air circulation, for example, near a window or radiator. Often the polluted air is sucked in at the back of the device. Ied again at the front. Therefore, corners of rooms should be avoided as an installation location. Positioning between furniture is not advisable, as it may obstruct the intake and output air flow.

FAQ: Frequently asked questions about humidifiers
Which is the best humidifier?
A blanket answer to the question is not possible, as it depends on the buyer's requirements for the humidifier. While some models are only enough for the size of a small bathroom, other devices are suitable for use in offices. Therefore, it is important that buyers are clear about what their requirements are for the product before purchasing a humidifier.
Where can I buy a humidifier??
A humidifier can be purchased in a local store – an electrical store or a supermarket during theme weeks – or on the Internet. Buying in a local store offers several advantages: Buyers benefit from personal advice and can estimate the dimensions and weight of the product themselves. For this, the selection of products at an online retailer is significantly larger. There models can be compared at a glance. There is access to numerous reviews from other customers. In addition, buyers can complete the entire purchase process at any time of the day-. Do it at night from the comfort of your sofa at home.
What do humidifiers cost?
The cost of a humidifier depends on the design, the capacity of the water tank and the scope of functions. An evaporator can be purchased for as little as a single-digit to low double-digit amount. Atomizers with ultrasonic technology are available for a low to mid double digit sum. For a humidifier that works on the evaporator principle, buyers usually pay a low double-digit sum.
How to clean my humidifier?
Whether the humidifier is used in the bedroom or in the office, it should be cleaned at least once a month. For this purpose, a mixture of water and vinegar essence is added to the water tank and the humidifier is switched on regularly. This is how to fight against bacteria, germs and limescale. If the device has a filter, it should be regularly replaced with a new filter or cleaned under running water, according to the manufacturer's instructions.
How humidifiers and air purifiers differ?

What oils can I use with a humidifier?
It is a good idea to use water-soluble oils so that the oil ends up in the spray mist and does not stick to the humidifier's water tank. The oils should be of high quality and without synthetic substances that are harmful to health. For example, peppermint, eucalyptus or citrus oils are ideal for use with an aroma diffuser. One to two drops of oil per 100 milliliters of water is usually sufficient.
If desired, different oils can be combined with each other. There are numerous books and blogs on the Internet that deal with the topic of aromatherapy. Should users have an allergic reaction to the use of the oils, the application must be interrupted immediately. The following symptoms may indicate that the oils are not tolerated:
– Headache – Coughing – Circulatory problems
