Ultrasonic humidifier: principle of operation, features, selection criteria


Humidifiers are devices designed to increase the humidity of the air in individual rooms and buildings in general. To do this, they generate water vapor.

The child is dear to every parent. Moms and dads do not want to see them sick. Children's illnesses hurt them. If a doctor prescribes the use of a humidifier or is intuitively convinced that moisture will help make breathing easier for a child with bronchitis, cough, or flu, then read this review to find the most appropriate model.

Typically, a cold steam generator is the best choice. Warm or hot air increases inflammation in the baby's airways.

Humidifiers provide a breeding ground for bacteria. They must be disinfected daily and distilled or purified water changed every day. Your child should not breathe in minerals and lime from city tap water. It is not worth pouring softened water into the humidifier either, since it is obtained from hard water by adding salts.

Benefits of using

Humidity is the concentration of water vapor in the air. It can be seen on foggy days. Air humidity varies depending on the season and place of residence. It is higher in summer and lower in cold winter. The humidity in the house should be between 30-60%. When it gets too high or too low, problems can arise.

Low humidity irritates the nasal passages, causing dry skin, itchy eyelids, and dry coughs.

High leads to the appearance of condensation on the windows, makes the atmosphere stuffy, makes breathing difficult and gives the feeling of being in a bath. High humidity activates unsafe bacteria, mold, mildew and dust mites. Allergies, asthma outbreaks and other respiratory illnesses can also be a consequence.

In addition, when humidity is too low, static electricity can become a problem, causing irritating tissue adhesion and small electric shocks when touching doorknobs or metal. Furniture can dry out and paper can dry out and crumble.

Humidity should provide comfort without causing health problems by being too high.

Principle of operation

In cold climates, this device will provide the necessary level of humidity in the room. Ultrasonic humidifiers (photo below in the article) use a metal diaphragm that vibrates at a high frequency, creating a cool or warm mist. Sound vibrations, acting on water, saturate the air with moisture. The liquid particles thus formed are so small that they are absorbed by the air almost instantly. The ultrasonic humidifier does not require a fan, so it is quiet.

When choosing a model, the human factor must be taken into account. For example, if there are small children in the house, then the question is whether the house needs a hot steam humidifier? It's probably better to choose another option.

Humidifiers and their positive and negative sides

pros

First of all, they are designed to create the necessary level of humidity in the room. When the air is dry, the mucous membranes become dry. This facilitates the entry of viruses into the body through the nasal passages. A healthy microclimate is especially important when the body is in the growth stage - metabolic processes are faster. For the development of immunity, it is necessary to adhere not only to proper nutrition, but also to breathe healthy air. In any case, it will not hurt both the child and the adult.

Normal humidity prevents the skin from drying out, this is especially true for people with dry skin type. After all, the feeling of dryness of hands, skin of the face in winter is especially worrisome. Normal humidity helps a person to recover after a hard day's work, to have a good rest. In the room where the humidifier is located, it is easier to sleep, it is enough to set the device to sleep mode, it will quietly perform its task.

A newborn needs a humidifier just like an adult. Babies sleep a lot, so that sleep is useful, it is necessary to create not only the recommended air temperature, but also humidity. The necessary conditions contribute to the fact that the baby will not only sleep well, but also eat. The risk of contracting a respiratory viral disease will be reduced to a minimum.

For people with allergies, it is also worth taking care of a healthy microclimate. Household dust plus dry air can be a major cause of allergic reactions. Therefore, if a dilemma arises - is it worth buying a humidifier for people suffering from allergic diseases, then you should definitely try.

Even indoor plants shed their leaves in the dry air in winter. They begin to hurt, the buds dry up during flowering, not yet opening. By purchasing a humidifier, you can easily improve the microclimate in the house.

Minuses

Like any mains powered household appliance, the humidifier is dangerous - especially if a small child is interested in it. The second point is that steam cleaners have a high steam temperature. Therefore, in the nursery, it should be installed in places where the child will not reach it, or buy an ultrasonic device or cold vaporization (traditional). Some humidifiers, if untreated water is poured into them, are thrown out with fine water droplets and harmful substances. Just like any other appliance, the humidifier requires maintenance, if this is not done, then mold will form in it.

Now it is probably clear why you need a humidifier in your apartment. However, picking it up is not easy. Perhaps you should not save money and buy an expensive model that will help to effectively provide the room with the necessary humidity. By investing in such a device, you can save on medications that you may no longer need. After all, normal humidity is a guarantee of health.

What is the best ultrasonic humidifier?

The first step is to decide whether to install a humidity control system for the whole house or just one room, usually a bedroom. As a rule, a small device in the nursery is enough for most users. However, those who live in dry, arid climates or have severe sinusitis, dry coughs, dry flaky skin and hair should consider a centralized hydration system.

It is necessary to purchase a device with the capacity and performance of which would correspond to the size of the particular room.

Portable and benchtop ultrasonic humidifiers are great for one room. For rooms of different sizes, tanks of different tank volumes are available.

Whole-home systems lead the way in ultrasonic humidifiers because they provide adequate humidity levels through ductwork and hydrostatic control. Retrofitting existing ventilation is expensive. Such a system is permanently connected to a water source and does not require replenishment of tanks. Installed by a heating and ventilation specialist who must calculate the required performance.

How to choose the right humidifier for your home?

Many people think that all humidifiers are just a simple plastic container with a water neck and a steam hole. In fact, this is just a stereotype, since it is the most common model that can be found in any supermarket.

In fact, there are dozens of types of humidifiers on the market today. All of them differ in parameters, as well as their purpose for work in different conditions. Below we will look at the features of each of them.

Evaporative Air Humidifiers

As the name suggests, these devices humidify the air by evaporating water. Evaporating devices include special replacement mats, water tank and fan. The operation of the equipment is extremely simple: the air is humidified and purified using the aforementioned evaporating mat. The tank also has a corresponding valve with which the humidifier regulates the water level.

Why are these models of humidifiers good? First of all, by its reliability and the ability to work in a constant mode. All thanks to the simple design and the natural humidification process.

Ultrasonic humidifiers

Their principle of operation is based on the destruction of water molecules using ultrasound, due to which a so-called water mist is created. The design of ultrasonic evaporators includes an ultrasonic membrane, a generator, a reservoir, a special chamber and a fan. When the air is humidified, it moves into the chamber, where the specified process of destruction of water molecules takes place. On the other hand, water is blown out of the chamber, which can be cooled or heated.

Why are such models good? Firstly, they can control the humidity level as accurately as possible. The disadvantage of this type of device is that it sometimes stains walls or ceilings.

Radiator humidifiers

These devices consist of steel or ceramic containers suspended from a radiator. They are "powered" by the heat from the radiator, which heats the water, which, due to evaporation, creates air humidification in the rooms.

The main advantage of radiator evaporators is, of course, an affordable price. Such devices are also unpretentious in operation. However, this type of humidifier is considered to be the most ineffective, and many homeowners complain that the effect of their operation is often not observed at all.

Steam humidifiers

The principle of operation of such devices is to transfer water from the reservoir to a special chamber where the heater operates. The water in the chamber is heated and then blown back into the room in the form of steam. Unlike other types, steam humidifiers do not heat all the water, but only the part that is needed to humidify the air.

Among the advantages of these models, we note that they are very effective and safe. In addition, when the water is heated, all bacteria are removed from it. The disadvantage of this type of humidifier is the high operating cost associated with high energy consumption.

Air humidifiers with ionizer

They are considered multifunctional air humidifiers, because in addition to the main function (air humidification), devices of this type also purify the air and also fill it with useful ions.If we try to describe their principle of operation briefly, such humidifiers reproduce so-called anions in the air, the task of which is to destroy positive ions, which often cause asthma, rheumatism and respiratory diseases.

Considering the fact that such humidifiers make the air more healthy, we can often find them in hospitals, clinics, kindergartens. In fact, they work like a huge inhaler, so if you are puzzled by the choice of a humidifier for a children's room, we recommend that you pay attention to models with air ionizers.

What to keep in mind when choosing a humidifier?

The parameters of the humidifier depend on the intended place of use and the desired purpose. Consideration should be given to characteristics such as performance, functionality, design, service, and warranties.

  • Performance. In most humidifiers, moisture yield is expressed in cubic meters over 24 hours. They are also estimated by the area of ​​the premises that they can serve. The performance of the purchased humidifier should correspond to the volume of the room or house. If the air is too humid (more than 60%), then favorable conditions for the growth of mold, fungus and bacteria will arise.
  • Features. Ultrasonic humidifiers generate both warm and cold mist. In devices of the first type, cold water is passed through a heating element. The fog leaves the ultrasonic machine at a safe temperature of 40 ° C. However, the water inside the device may burn the baby if it is tipped over. Therefore, it is safer to use cold fog machines near young children and the elderly.
  • The best ultrasonic humidifiers use hygrostats. They measure moisture and provide it at a given level without requiring additional calculations.
  • Design. If the intended installation location of the device is known, it should be measured to ensure that it will fit. The humidifier must be easily carried to the water source to replenish it. It should have handles so you can move it when wet.
  • Service and warranty. Most humidifiers usually come with a 1-year warranty. But it is better to buy devices from manufacturers who support their products for a longer time. You need to make sure the company provides a toll-free phone number or live chat to help users. It is better to choose a reputable company that advises its clients.

How to choose the right humidifier, is it worth buying?

Humidifiers are a tricky choice. Many people think that a humidifier is desperately needed, but after buying it, they quickly throw it into a far corner - it did not really fit in terms of consumer qualities. The choice of a humidifier turns out to be not so easy, so you should not take the first one. Let's figure out how to choose the right humidifier and when to purchase it.

Why the air becomes dry

They say that "batteries dry the air", "the heater dried the air for us." In fact, Winter dried the air.

In winter, the humidity outside drops to 15 - 30%. In the summer there are no problems with this, it is enough to open a window and the room will be in accordance with SNiP - 40 - 60%. In autumn and spring, the humidity is high. But in winter, when the temperature difference between indoor and outdoor is maximum, the radiators operate at full capacity, and the partial pressure also rises, which expels steam through the structures and through the ventilation from the rooms to the street. It is impossible to stop the process without reworking the building.

At the same time, many people are very sensitive to a decrease in humidity and 20 - 30% is not acceptable for them. Especially little kids love comfort. Due to dry air, they even have nosebleeds. It is desirable for them to always maintain a comfortable rate of 50 - 55% humidity. What is the best way to do this?

What to do if the air feels dry

  • First things first, check the actual humidity - what percentage? This requires a hygrometer. Maybe you can take such a device from friends? If not, then it is inexpensive.

  • Consider purchasing a humidifier. Before proceeding with the purchase, familiarize yourself with the designs and capabilities of various devices more closely, how they differ, what are their shortcomings.

Humidifier options

There are climatic complexes that maintain both humidity and temperature, purify, ionize, humidify the air. But they are expensive and are permanently installed. It is not so easy to equip a nursery with such equipment in winter for a quick hand.

Indoor humidifiers are currently of three types.

  • Steam. They work on the principle of a kettle - an electric heater evaporates water, hot steam enters the room.

  • Mechanical. A fairly powerful fan blows through filters filled with water, blows water mist into the room.

  • Ultrasonic. The vibrating membrane at a frequency above the threshold of our audibility, with its vibration, sprays water, creating a fog, which is picked up by a jet from a small fan and enters the room.

Let's take a closer look at the work and design of each - which one can be useful to us?

Steam

  • It consumes a lot of electricity to heat water, it is equipped with a powerful heating element, which is not cheap to work with.
  • It is hot itself, gives out hot steam, it is unacceptable to find a small child nearby.
  • Equipped with anti-rollover protection, and in some it is possible to add flavorings - but how important is it and who needs it?
  • Produces gurgling, hissing, gurgling sounds, can be unpleasant at night.

Mechanical

  • Usually the impeller hums soundly and interferes. A powerful fan cannot be completely silent. Therefore, such a device is often used periodically and in not quiet places, as long as it can be tolerated, and not at night.
  • There are models that are more expensive, noise-protected, but is it worth it to overpay and try to listen in the noise of the store, "is it really quiet", so that later in the silence of the house you find out that "it is not very quiet."
  • Here, as a rule, there is also an ionizing silver rod, the filter is called "antibacterial" - manufacturers attract the attention of buyers.

Ultrasonic

  • The device includes a softener filter so that water is more easily converted into mist. It is not known exactly what he adds to the water, but on objects, on furniture, and therefore on us, a white coating remains after the device is operating. Is it safe, and is it okay to wipe the room after humidifying the air?
  • Otherwise, it is more or less quiet and does not bother with other obvious shortcomings. True, sometimes it is equipped with a bright display, which more often only interferes, and is especially not appropriate for small children ...

What to choose and how to apply?

One forum member spoke about the choice of a humidifier for a children's room, something like this: “After getting to know different humidifiers better, I wanted to return to the jars of water screwed to the batteries. Yes, - super-archaic, but quiet, safe, will not poison, no problems, and is worth nothing ... "

  • Most people still consider ultrasonic humidifiers to be the most advanced, they are called suitable for children, despite the strange plaque ...
  • Mechanical ones are considered good-quality business executives, they are used in kitchens, in noisy places - they made noise and stopped.
  • Steam is more likely for offices, where the chief will pay for the electricity ...

Do not overpay for the display, built-in hygrometer, and other electronics - the essence of this does not change, and the humidity should be measured away from the device. A hygrometer is placed, for example, near a crib, and all work is adjusted according to it ...

With an increase in air humidity, the temperature is felt much more sharply. Humidity rises to 60% - +20 - it gets cold, +30 - it gets hot. Therefore, it may also be necessary to adjust the temperature ...

Criteria for the right choice

Ultrasonic humidifiers increase the comfort of your home. The right choice will satisfy all your needs. These devices are inexpensive and easy to use. Here are some specific guidelines for choosing the perfect humidifier:

  • Area. It would be redundant to integrate a humidifier into an existing ventilation system if all that is needed is to occasionally increase the humidity in one room. A small, portable device can easily provide the comfort you need and save money. To calculate the serviced area, you need to multiply the width of the room by its length. For example, a 4 x 5 m room is 20 m2.
  • Operating costs. The initial installation of a humidification system for the whole house is more expensive, but is generally cheaper. Warm mist vaporizers are cheap but consume a lot of energy. The operation of the humidifiers can be controlled with a hygrostat. Replacing filters and cartridges is another expense. These costs can make the air humidifier too expensive.
  • A hygrostat is an analog or digital instrument that uses a hygrometer to control the humidity in the air. Hygrostats are important because without them, fog will continue to be generated until the humidifier is manually turned off. Excess moisture leads to the formation of condensation on the windows and the appearance of mold and mildew in the room, therefore a portable hygrometer should be used to control its level.
  • According to reviews, the ultrasonic air humidifier produces almost no noise, with the exception of a slight hiss.
  • Water quality. When hard tap water is used, many humidifiers will have a lower fog output. This increases the cost of service. The use of distilled water can be economically viable, but it also requires additional costs.
  • Safety. It is advisable to purchase a device that automatically turns off when there is no water. Top-rated ultrasonic humidifiers emit an audible alarm when liquid levels are low and need to be refilled. The transparent reservoir will allow you to determine the moment when you need to refill it. For example, the Polaris PUH 7140 ultrasonic humidifier switches off automatically when there is no water.

Humidifier Polaris PUH 7140

  • Warm or cold? Some people prefer a cold mist to a warm steam, reminiscent of the atmosphere in a steam bath. Others prefer the soothing warmth, which they feel softens the air. These are personal choices, and your doctor may recommend which one is best for your health problems. If medications are used, warm steam generators are better suited. Ballu UHB 1000 ultrasonic humidifier, for example, supports 2 modes - cold and warm fog.

In dry climates, humidifiers are needed during the cold winter months and often throughout the year. Humid air feels warmer and provides greater comfort. It becomes easier to breathe, and the habitat receives the moisture it needs.

What are humidifiers?

As you might guess, these devices are designed to increase air humidity in the rooms of houses and apartments. What does a humidifier give us? Thanks to its work, our lungs and mucous membranes receive air of normal humidity, which has a positive effect on health.This is especially important in winter, during the period of maximum battery operation, which, as we noted above, dry the air in rooms.

The principle of operation of all humidifiers is extremely simple, and is based on the release of steam from water. The device absorbs dry air inside, which is then cleaned with filters and then humidified with steam and finally returned to the room. Naturally, the air is humidified not immediately, but gradually. The longer the humidifier is on, the more humid the air in the room becomes.

What is the difference between cold and warm fog?

There are not many differences. Cold fog makes breathing easier for allergies, asthma and respiratory problems. If it is easier for the user to breathe in a bathtub filled with steam or in high humidity, such as in the rain, then warm steam will be preferred. Otherwise, it is better to use a cool mist. A heating element is needed to create warm mist. This is the reason that it is not the best option in homes with small children and pets.

Varieties of devices

Before giving any recommendations on choosing a humidifier, you need to figure out what types of devices exist:

  • Natural evaporation humidifier. The device in this case is extremely simple - a container of water with a cooler that blows out the evaporating water, thus producing cold steam. This type is characterized by a low level of efficiency and is a poor option for a home with small children, since the air is humidified rather slowly.
  • Steam - moisture enters the air of the apartment in the form of hot steam. The principle of operation of this type is quite simple - humidification is carried out by heating water. A boiling kettle is an obvious example. A steam humidifier has 2 significant disadvantages:
  1. High energy intensity. The heating elements are characterized by a high level of energy consumption.
  2. Low level of safety, it is necessary to ensure that the humidifier is in a place inaccessible to a small child, as the baby can get burned. And adults need to be careful.

The advantage of choosing this type is the ability to combine moisturizing and aromatization.

  • Ultrasonic type - the principle of operation of such a device is based on the vibration of the membrane, which turns water into the smallest aerosol. Mist and humidifies the air in an apartment or house. This technology is considered the most effective in terms of humidification, energy consumption, and safety. The advantage is also the speed of operation, the increase in humidity begins immediately after turning on the device. Disadvantage - the use of water with impurities will lead to the appearance of a white bloom in the apartment.
  • Air cleaning is nanotechnology. A complex that automatically creates an optimal microclimate in the apartment: it cleans and ionizes the air. The choice of a type of device with a purifier and an ionizer is complicated by the high cost. It is several times higher than the price of the above three types.

All types of household humidifiers have only one feature in common - the absence of noise. We figured out the types, now let's talk about what functions you need to pay attention to if you want to choose an inexpensive but good humidifier in 2017.

How do humidifiers deal with bacteria?

Models are available with functions to limit or prevent the growth of bacteria in the water tank. Some of the top-rated ultrasonic humidifiers use nanotechnology or silver for this, but are more expensive. But you still have to clean and disinfect the device, as well as distill the water to limit the growth of bacteria. While these humidifiers are more expensive, they are worth it because they last longer.

For example, the Polaris PUH 7140 ultrasonic humidifier has a special coating on the water tank that contains silver particles, the disinfecting properties of which are well known. In addition, this model is equipped with a water purification cartridge and two air filters that remove odors and dust.

What kind of water to fill in humidifiers

The performance indicators of the device and the process of humidifying the air in the premises directly depend on the quality of the water.

Each specific humidifier requires a specific fluid approach.

Before use, be sure to read the instructions from the manufacturer. Some models have their own nuances in the work.

For example, water entering the ventilation duct will break most ultrasonic ones (for example, in the popular Boneco Air-O-Swiss AOS U200, etc.).

Model manufacturer Timberk THU UL 03 A1, recommends filling the tank with clean water every day, do not add essential oils, detergent, warm water over 40 °C.

A different fluid composition will attack internal parts and cause malfunction.

Basic instruction

  1. Before filling the reservoir with water, switch off the power supply to the humidifier and unplug the mains plug.
  2. Use only clean water, cold tap water. If your home has hard water with a high mineral content, use filtered, distilled water.
  3. Do not turn on the humidifier when there is no water in the tank
  4. Pour cold water into the tank no more than 40 ° C (such requirements are set by most manufacturers of ultrasonic humidifiers, for steam humidifiers the limit is no more than 60 ° C. The exact temperature can be found in the passport of the device.
  5. Add flavors strictly according to the instructions.

There are models with aromatization, there is a tray (capsule) for aromatic oils. In the instructions from the manufacturer, it is forbidden to add essential oil without this function. Ultrasonic devices are especially sensitive to this.

How often should the humidifier be cleaned?

It is imperative to read the user manual. An ultrasonic air humidifier requires regular maintenance to stop the growth of mold, mildew and bacteria. Do not leave the device wet as this leads to the growth of pathogens. A good rule of thumb is to change the water daily. Maintaining this practice means that you can thoroughly clean and disinfect the device not every day, but only once a week. This must be done so that contaminated moisture does not get into the air. The cleaning procedure should be carried out in accordance with the manufacturer's recommendations.

Why does white dust appear on furniture, floors and around the humidifier?

These are minerals found in hard water. They are not harmful and are easy to clean, just like ordinary dust. Ultrasonic humidifiers, unlike evaporative humidifiers, can become a source of these salts if they are not equipped with a high-quality demineralization cartridge. Distilled water should be used to combat this phenomenon. Plus, it will help your filter last longer and won't have to be cleaned as often. However, the water will still have to be changed every few days and the device should be disinfected according to the manufacturer's instructions.

Can hard water be used?

It is imperative to read the user manual as different brands and types of humidifiers have different requirements. If the purchase of a device is only planned, then it is better to purchase one that has a mineral cartridge. Hard water from a tap or well contains minerals that can build up inside the device. These can cause the fog to leave white spots and dust around the area of ​​the humidifier. Inhaling minerals over time can worsen respiratory conditions or cause new problems. The cartridges filter minerals from hard water, eliminating the need to inhale them.If there is no cartridge, it is better to use distilled water, which does not contain salts. It should be noted that, for example, the ceramic cartridge of the Polaris PUH 7140 ultrasonic humidifier, according to the owners, does not help to get rid of the formation of white dust.

Harm

Very often there are disputes and disagreements about the benefits and harms of an ultrasonic humidifier, let's try to understand this issue.

Mineral dust deposited during the operation of this type of humidifier can be harmful to health, because a person inhales it together with the air, therefore, people with allergic diseases or asthma are not recommended to use ultrasonic humidifiers. During operation, it is necessary to monitor the cleanliness of the inside of the device and change the filters in time. microorganism growth can form and, if sprayed, toxins can cause lung disease.

Cough from an ultrasonic humidifier

Also, many users observed the "heaviness" of the inhaled air and coughing. To cope with this problem, as mentioned above, the use of distilled water will help, but this does not always help, it all depends on the personal feelings of the person.

The ultrasound itself does not cause harm. it simply converts the water into a state of steam without changing the composition of the water.
