Humidifier: answers to typical questions
A humidifier is needed to keep humidity in the room at the right level. Decreased humidity in heated rooms during winter is bad for the respiratory tract. Dry air dries out the mucous membranes and forms hard crusts of dried mucus that obstruct the free flow of air in the nasal passages. Consequently, the protective properties of local immunity falls sharply, increases the likelihood of blockage of airways and sinuses, the development of this condition of severe bacterial complications. It is especially important to maintain normal humidity for infants and children of preschool and primary school age, since they are much more sensitive to dryness due to the smaller size of the respiratory tract and the peculiarities of metabolism.
A healthy child sleeping and often going for walks at 18°C maximum is normally exposed to the humidity of 40% to 60%. 40% is a minimum. Well, for a sick child or seriously ill child, reducing the relative humidity level in the children’s room to 50% or less is fraught with increasing the severity of the condition and the likelihood of complications. But even a humidity of 60-70% is not reasonable.
Adults are much more robust and are better adapted to low humidity, but a normalized humidity level is also very beneficial for their health.
From this we can conclude that a humidifier is needed primarily for the health of children, but adults, too, will be useful.
Why is the humidity in the premises not normal in winter??
The water solubility of the air is directly related to temperature. The higher the temperature, the higher the solubility, the more water in a gaseous state can be retained. In winter at minus 10˚C the outdoor air contains not more than 2 grams of water in 1 cubic meter of air. Once inside and warmed up, the air continues to contain the same amount of moisture as outside. But the potential capacity of air with respect to water when heated to room temperature increases dramatically. For example, the absorption capacity of air has changed from 2 grams at.10˚C to 17.5 grams at 20˚C of water in a cubic meter of air. Accordingly, the saturation of the air with water vapor changed from 100% to 11.5%, or, in other words, the relative humidity in heated air decreased from 100% outside to 11.5% indoors.
The presence of pasteurization in the device not only reliably solves the problem of suppressing microbial growth, but also significantly increases productivity due to the presence of the thermal component.
The disadvantages include the fact that together with water all impurities and minerals dissolved in water are thrown into the air, which, after drying microdroplets in flight, continue to fly smoothly around the room, settling gradually on all surfaces. This peculiarity of the principle imposes additional requirements for the mineralization of water. You can not have enough distilled water, and boiling, adding to the hassle, will only partially reduce the level of lime, leaving many other components that will long fly around the apartment, staining the flame on the gas stove in different colors. In many cases, hot tap water has a level of impurities that can be tolerated. But still more suitable for such a device water from the first stage of reverse osmosis domestic filter system.
What are the advantages and disadvantages compared to other types of steam humidifiers?
The main advantages. high performance, little related to the level of humidity, the absence of impurities in the evaporated water, sterility.
The disadvantages are the need for frequent maintenance to remove limescale and the relatively high power consumption of some models.
If you need a device that is guaranteed to quickly fill the air with clean moisture without impurities, it’s not a bad option, if the model is sufficiently productive.
But in emergency cases, as an alternative, any dish will do. a bucket, a basin, a kettle or a pot. placed on a safe source of heat.
What are the advantages and disadvantages compared to other types of humidifiers with the natural principle of evaporation?
Their main advantage is the “naturalness” of evaporation: water evaporates from a large area of constantly wetted surfaces. The intensity of evaporation is regulated by the humidity in the air. the lower the humidity, the more intense the process. Humidity has risen to the upper limits of the norm. evaporation slows down. Plus the moisture evaporates and immediately transforms into a gaseous state, and all the impurities and minerals remain in the liquid phase inside the appliance. The air saturated with moisture by such a device is perceived more comfortably, naturally than when using an ultrasonic humidifier. The result of operating such a device is equivalent to being in a room with an area of 1-2 m², on which a fan is constantly blowing.
To devices of this type belong “air washers” and various devices with wetted wicks, nets, with a turbine, splashing water, and many others. In my opinion, only air washers with a set of flat wetted discs mounted on a rotating axis are really effective. Let’s consider this variant, and disregard the other designs as notoriously unsuitable.
In the “air washer”, a set of discs is coaxially mounted on a rotating axis and partially submerged in water. During rotation, the discs are constantly moistened in a bath, and over the surface of the water dry up under the influence of the air flow from the fan. The air is saturated with moisture as it passes between the discs, and the dust it contains is partially deposited on the surface of the wet disc and then washed away in the tub. So, these devices have a double effect. humidification and removal of dust from the air. For all the simplicity of design, there are devices, made by 2 different structural schemes. According to one scheme, the water is supplied from the removable reservoir to the tray for wetting the disks, and according to the other scheme, the disks are in the tray, which itself is a reservoir. The difference, it would seem, is insignificant, but essential.
In the first type of construction, the water in the tub is changed only when the device is completely serviced, and a removable reservoir is used for refilling, the water from which is pumped into the work tub, it should be noted, with a loud enough to wake up the sound. Thus, during the topping up the water also comes with impurities, whose concentration is constantly increasing, increasing 10-fold by the end of the first filling and 20-fold by the end of the second one. In seven days, the concentration of impurities can reach one hundred times that of the original water. The concentration of dust and the concentration of microbes and algae grows in parallel. In my opinion, using an opaque murky cocktail as source of moisture is unpleasant and unhelpful.

Heat: air conditioning and humidifier
The main problem that appears in summer is the high ambient air temperature, which cannot be reduced by airing: it’s hot everywhere. It is known that the respiratory system, besides its main function (gas exchange) plays a huge role in maintaining the body’s thermoregulation. No matter what type of air we breathe in, when it passes through the respiratory system it heats up to body temperature and saturates with water vapour by up to 100%. Thus, the exhaled air has a humidity of 100% and a temperature of, roughly, 36.6 ° C. It is quite logical and obvious is that if a child breathed in air 20 ° C and exhaled 36.6 ° C, then in the process of inhalation and exhalation, the body loses a certain amount of heat.
A fundamental characteristic of warm-blooded animals in general and humans in particular is that the process of vital activity is accompanied by a constant production of heat. A feature of cubs, and the human cub is no exception, is a more active metabolism compared to adults, hence they (cubs) produce much more heat per unit time than their parents.
The process of heat production is called heat production. The heat produced must be disposed of, and this process is called heat dissipation.
Nature has provided for two main ways of heat production:
- Through the skin (direct heat transfer by contact of two environments with different temperature plus evaporation of sweat);
- through the lungs (heating of inhaled air).
The fundamental peculiarity of children is the immaturity of sweat glands, so at children’s age the main way of heat regulation is exactly breathing, and this provision is the more relevant the younger the child is.
High air temperature makes the organism unable to give off the heat through the lungs, as a consequence. the load on the sweating system dramatically increases, the organism loses a lot of fluid, blood thickening occurs, and violation of blood rheology (thickening) reflects on the rheology of mucus (for the worse, of course). And in disease conditions, the development of inflammatory process is accompanied by the growth of heat production, which makes the high temperature of inhaled air even more undesirable. The main condition for the normal functioning of the local immunity, ensuring the fight against the disease, is the maintenance of the proper rheological properties of the mucus.
High humidity of inhaled air prevents mucus thickening. this is good and quite obvious. High temperature of inhaled air worsens the rheology of mucus. this is bad. If this statement does not seem obvious, you should just imagine that you sweated because of the heat and your mouth is dry.
All the above is an attempt of physiological justification of a simple recommendation: temperature of 18 °С and relative humidity of 60-70% are the parameters optimum for the room where a child is, especially for a child suffering from acute respiratory infections.
Two practical questions follow from this theoretical knowledge:
How to Control Temperature and Humidity of Air?How to regulate the temperature and humidity of the air?
Temperature control is never a problem, as a rule, with anyone. A room thermometer (liquid, spring, electronic, etc) is an ideal temperature and humidity meter. п.). this thing is quite accessible and easy to handle. It is recommended to place it at a height of 1 m from the floor, and it is very desirable in this case, that nearby there were no heating devices.
An instrument designed to measure air humidity is called a hygrometer. There are several types of hygrometers, fundamentally different in the way they measure humidity (chemical, electric, hair, condensation, etc. д.). You should know that a really accurate hygrometer is not an easy thing, it’s often bulky, expensive as a rule At the same time, any domestic needs can be fully satisfied by a hygrometer, which is not a pretender to the truth in the last resort and has an error of 3-5%. This particular hygrometer is compact, affordable, inexpensive. This is something that looks like a clock. either hand or electronic.
So long as we started talking about clocks, we should emphasize that from a practical and economic point of view, the most convenient are electronic multifunctional devices that combine a clock, thermometer, hygrometer and, if desired-necessary, many-many others (calendar, barometer, moon calendar, weather forecast, etc.). д.).
Having understood the ways of control, let us now consider ways to regulate temperature and humidity. The main thing to consider is the close relationship between these parameters.
The main difference between summer heat and winter heat is that there is no cold air anywhere, t. е. knowingly no air in which there is little moisture. That’s why in most regions it’s warm in summer, but not dry.
High ambient temperatures, as we already know, cause the child to lose a lot of fluid as he is forced to regulate heat loss through perspiration. If this liquid manages to return back in the form of abundant drinking. the situation is quite controllable and not dangerous for the local immunity. And if you can’t get it back? Well he doesn’t want to drink, for example, or he sweats so actively that he can’t drink so much. This is already both more difficult and more dangerous, and the best solution in such conditions is to cool the air. The air conditioner is the basic and all known device for air cooling.
The initial information about air conditioning may seem paradoxical. Judge for yourself: heating of air leads to decreasing of its relative humidity, and cooling of air leads to decreasing of its relative humidity. also leads to a decrease in its relative humidity. Nevertheless, a small but very fundamental clarification: not just cooling, but cooling with air conditioning.
The point is that the theoretical basis of air conditioning is the property of liquids to absorb heat by evaporation and to release heat by condensation. We are not going to touch here upon the nuances of compression, thermoregulation and ventilation, we will not discuss nuances of liquid and gaseous freon circulation. We only can state that during air conditioner’s work the contact of air with cold surface takes place and it is accompanied by condensation of moisture, which is derived from the premise through the drainage hose.
As a consequence air conditioning leads to dehumidification. (By the way, the first industrial application of the conditioner in 1902 was used not for cooling, but exactly for drying the air!)
How to clean humidifier?
All humidifiers need periodic cleaning. To clean the appliance from limescale, you must take out the water tank and disconnect all parts from the unit that are possible. If there is residual water in the tank, pour it out and rinse the tank thoroughly under the tap.
Before pouring detergent into the humidifier tank, the body of the device should be wiped with a soft cloth with a solution of ordinary table vinegar
Membrane humidifier cleaned with a special brush, which is sold with the device. If this brush is lost, it can be purchased separately at hardware stores.
As an alternative, sometimes a small sponge without metal threads or a fleece cloth is used. In order to keep the sealing material tight, the unit should be thoroughly dried between applications by removing the plug.
Only soft cloths may be used to clean the water tank. Brushes with hard surfaces can cause scratches inside the tank. If too much scale has accumulated in the tank, you must take a toothbrush with soft bristles and ordinary table vinegar 9-15%.
To clean your humidifier with vinegar, you need to:
- Open a balcony or window as acetic acid fumes are harmful to health.
- Dilute half a cup of vinegar (100 ml) in 2.5 liters of clean room temperature water.
- Pour the mixture into the humidifier tank.
- Plug the humidifier and run it for one hour at high speed (the humidifier spout should be turned to the window, it is better to leave the room for this period, closing the door tightly).
- Shut down the humidifier, disassemble it and thoroughly wash each part with water.
In addition to vinegar, citric acid, baking soda, hydrogen peroxide, and bleach with chlorine can be used to clean the device. Citric acid can help safely remove plaque.
Baking soda destroys film of rot and mold inside the device, which can appear because of high humidity. Hydrogen peroxide disinfects the humidifier tank. Bleaches destroy pathogenic microflora in the tank and prevent it from reproducing.
In addition to folk remedies for cleaning the humidifier you can use commercially available descalers: Top House, Luxus Professional Technics, Unicum, BONECO A7417 Calc Off, etc.д.

Filters in your humidifier need to be changed every few months. The exact replacement time depends on the type of appliance and the quality of water used.
These filters must also be rinsed periodically under running water. Do not use aggressive chemicals for cleaning: they cannot be completely removed with water.
The best part:
Most homeowners would agree that most of the time spent in the kitchen is spent cleaning.
Conclusion and helpful video

Influence of humidifier on night snoring
A man who snores in his sleep, not only does not sleep well, but also does not allow the rest of the family. According to the world statistics, every fifth person suffers from snoring. To get rid of this ailment can be done in different ways: on sale there are drugs that belong to classical or non-standard medicine.
Snoring is most common in men 30 years and older. Many doctors attribute the appearance of this sound to the presence of weak palatal muscles. Causes of snoring are as follows:
- neurological problems;
- Consumption of alcoholic beverages and smoking;
- all kinds of abnormalities related to the special structure of the airways.
Snoring or rohnopathy is a disturbed breathing process that occurs when there is not enough oxygen. As a result, all sorts of serious complications in the form of cardiovascular disease, thyroid problems, and even a stroke are noted.
Snoring is often directly connected with the quality of air in the house. Significant harm to the body is caused by dry air masses that dry out the mucous membrane of the nasopharynx, causing snoring.
As a result, a high load on the cardiac system is noted, and swelling of the mucous membranes occurs if measures are not taken in time. Thus, an important answer to the question, why humidify the air in the room before and during sleep?
When humidification is needed around the clock
There are a number of times when you need to turn on the equipment for 24 hours a day:
- Humidity level in the room is much lower than the established norms.
- The productivity of the device is very low.
- The room is home to a large number of moisture-loving houseplants.
- There is no opportunity to ventilate the room.
- There is hot weather outside.
When selecting the appropriate model it is advisable to pay attention to the capacity of the water tank and the duration of operation of the device.
