Ultrasonic evaporator circuit. Do-it-yourself air humidifier at home: designs and assembly diagrams

To humidify the air in the room, a special device is connected - an air humidifier, which is presented in a wide variety. So, in addition to traditional installations, you can purchase steam, ultrasonic and even washing. To choose a humidifier, it is important to know how each type of appliance works. It is this question that will be discussed next.

Traditional Humidifier

This is the simplest type of humidifier. Its mechanism of operation is based on the natural process of evaporation - it's like hanging wet linen around the room to increase humidity. The device itself looks like this:

The principle of operation of such a humidifier is as follows:

Water is poured into a container, from there it flows into a sump, and then rises through the evaporator.
Air moves through this element with the help of a built-in fan, where it is saturated with moisture and disinfected thanks to filters that trap dust particles, pet hair and other contaminants. Therefore, the filters are washed every 2 weeks.
Evaporative elements are cassettes made of antibacterial impregnated multi-layered paper, which have a rather short service life. More expensive models use sponge cartridges or plastic discs, the surface of which has many cavities.

Its advantages include:

ease of use;
low price;
safety for children;
low power consumption;
the impossibility of waterlogging the air.

Cons of the device:

cassettes need to be changed every 2-3 months;
can not use tap water(effectively it works on distilled water);
has an average noise level;
slow hydration.

We will tell you more about the benefits and harms of humidifiers in the next article.

Steam humidifier - hot evaporation device

The principle of operation of this device is similar to the operation of an electric kettle, only unlike the latter, water enters the heating element in a small amount, and the rest of the liquid remains cold in the tank.

A steam humidifier increases the humidity in a room by constantly heating the water to a vapor state. Here is the scheme of his work:

Water is poured into the body, which is usually made of high-strength, heat-resistant plastic.
Close the lid tightly and turn on the device. If the lid is not properly closed, the device will not work.
The heating element heats the liquid up to 80 °C, steam escapes through the holes and humidifies the air. When the water level is low, it will turn off automatically.

Some models are equipped special nozzle and an aroma oil reservoir that turns the humidifier into an inhaler or fragrance.

This device has the following advantages:

cleans the air from pathogenic microbes and bacteria;
the released steam does not contain salt, which means that they will not settle on the surface of the furniture;
You can use any water, including from a tap;
compact models used as an inhaler;
quickly raises the humidity.

But it is not without its shortcomings:

this is an energy-intensive device, so it will not be possible to avoid high energy costs;
there is a high probability of strong heating of the body, which is dangerous for children, and if the device is overturned, you can also get burned;
when working, it makes rather loud gurgling sounds;
does not clean the air of suspensions.

The device has a fairly simple structure, which can be seen in the diagram:

The principle of its operation is as follows:

Water is poured into the container. In order not to form a precipitate or plaque on the walls of the humidifier, use the most purified soft water. The best option is distilled water.
From the container, the liquid enters the evaporation chamber, where there is a membrane that performs high-frequency vibrations. This causes the smallest droplets of liquid to come off the surface of the water and turn the water into a "cold" vapor, which resembles a thick fog.
In order for the steam to rise up to the spray nozzles, there is a fan inside the humidifier.

More expensive models equipped with the following items:

cartridges, passing through which water is additionally purified and softened;
an ultraviolet lamp for bactericidal treatment of steam, which completely eliminates the ingress of pathogenic microorganisms into the air of the room.

There are also advanced models of ultrasonic humidifiers on the market, which are combined complexes consisting of several filters for air disinfection:

water;
with antibacterial impregnation;
photocatalytic.

Often, hygrometers are installed in devices that measure humidity. environment, and its indicators are displayed on the LCD screen. At the same time, a person can independently set the required air humidity, and when it is reached, the device will turn itself off. Often, an ionization unit is also installed. Air ionizers increase the amount of negative ions in the room, which allows dust to settle on the walls and floor, and not “hang” in the air. Read more about the ionization function in the humidifier -.

Almost all models automatically turn off when the device capsizes or when the water level reaches a critical point.

This principle of operation is used, for example, in Polaris humidifiers. They have a hygrostat that allows you to regulate the level of steam produced. The manufacturer produces several models of the device with a variety of functions - from budget humidifiers, where there is nothing superfluous, to multifunctional complexes that not only moisturize, but purify, heat and disinfect the air in the room, creating a favorable microclimate for households.

These models have appeared on the market relatively recently. Their advantages:

produces "cold" steam;
works without heating water, therefore it consumes a minimum amount of electricity;
works practically without noise;
safe for children.

The disadvantage is the sensitivity of the device to hard water. It will shorten the life of the appliance, causing it to fail, and a white salt coating may appear on the furniture.

"Washable" humidifier

In the device, the main element is rotating plastic discs that beat water to the smallest particles. They can be seen on the diagram:

The principle of operation of such a humidifier is as follows:

The discs are constantly spinning and wetted with water.
The air, passing through them, is saturated with moisture and at the same time is cleared of dust that settles on their surface.

except mechanical cleaning, the device is equipped with an ionizer, and some models with a silver rod, which allows you to purify the air from numerous pathogenic microbes and bacteria. An essential oil cup can also be built in, allowing the humidifier to be used as a fragrance.

From the name it is clear that this device, in addition to moisturizing, also has a cleaning function. Advantages of the device:

does not require Supplies;
supports the function of ionization and aromatization;
disinfects the air;
does not require a lot of electricity.

The disadvantage is that it does not capture odors, chemical substances, tobacco smoke.

Among humidifiers, this is the most expensive device. It has all the advantages of previous devices, but first of all it purifies the air, and then moisturizes. Perfect filters cope not only with dust, wool, but also with odors, microorganisms, mites, plant pollen.

The disadvantages are:

the high cost of replaceable filters, which are changed once a year, and cartridges that require replacement up to 4 times a year;
enough high flow electricity;
large dimensions of the device.

The mechanism of operation of the apparatus consists in running air through a series of carbon filters, membranes with antibacterial impregnation and an evaporator. An ionizer is built into the device, and some models are also capable of aromatizing the air in the apartment.

Video: How does a humidifier work?

The video describes in detail the principle of operation of air humidifiers:

So, we told you about the operation of the main types of humidifiers that are used in apartments. When buying, you should take into account your needs, the area of \u200b\u200bthe room and how much money you are willing to spend not only on its purchase, but also on the operation of the device.

If you have small children or pets at home, it is better to opt for cold steam humidifiers.

In contact with

The ingenuity of craft lovers truly knows no bounds. For example, many people prefer to make various simple appliances for the home, while spending a minimum of money and effort. In this article we will tell you how to assemble a household air humidifier from improvised materials with your own hands and give detailed diagrams actions for each described method.

Before proceeding with the assembly of a home-made unit, we advise you to understand the algorithm of its operation. As a rule, the humidifier functions according to the following principle: water is poured into the tank, and then it evaporates. Thanks to the formed steam, the air in the room becomes more humid. Some housewives apply this rule in everyday life: they pour water into the basin, lower a cloth or towel on top and in this way increase the humidity in the room. True, this method is not very effective, and it increases the level of humidity only in the immediate vicinity of the pelvis.

Of course, modern devices work much more complicated, and this should be taken into account before creating your own humidifier. Traditional humidifiers work on cold steam using the built-in fan and filter cartridges. Steam models reminiscent of how they work Electric kettle : their main mechanism is internal a heating element, or heating element. And finally, ultrasonic devices are based on the operation of a piezoceramic membrane, using alternating current transforming water into tiny particles water mist, which subsequently enters the room.

Based on this simple knowledge, you should imagine what kind of device you want to get. We will highlight some of the most popular and understandable ways to make both a humidifier and an air purifier.

Yes, that's right: the simplest humidifier can be built from ordinary plastic bottle! Such a device gives cold evaporation effect.

We will need:

10 l plastic bottle;
desktop computer cooler;
tape or duct tape.

Cut the neck of the bottle so that you can easily insert computer cooler. Pour water into the existing tank.
Immerse the cooler in this hole and secure it with tape. You can also cut out fasteners from cardboard or a piece of thick paper. For the second option, it is enough to make a slot that is inferior in size to the cooler body itself and attach it to the bottle, additionally wrapping it with adhesive tape.
Turn on the cooler in the power supply. As a result, the air in the room will receive enhanced moisture.

From expanded clay and buckets

To develop this device, we need expanded clay. This material is able to absorb moisture well and, accordingly, release it.

Here is a list of items we will need:

4 waste baskets: 2 small and 2 larger;
a bucket with a volume of 10-12 liters;
aquarium pump;
computer cooler;
building hair dryer high temperature heating;
plastic straps.

Instructions for creating a humidifier look like this:

We attach two medium-sized wastebaskets to each other along the edges of the rims. This can be done using a household hair dryer or ordinary plastic ties. This is how the body of the future humidifier is formed.
In the same way, we connect larger baskets, having previously placed inside a body made of smaller baskets. It turns out a two-layer design, according to the principle of operation, reminiscent of a thermos or a heater.
Cut off the bottom of the basket that is on top. In some cases, it is enough to simply make a hole large enough to fill expanded clay inside. Keep in mind that expanded clay should be so large that it cannot seep through the holes in the trash cans.
We place the aquarium pump at the bottom of a pre-prepared bucket. We direct the tubes from the pump to the very top of the homemade case from mesh baskets. As a "cover" of the structure, we install a plastic ring with holes. From here, moisture will flow down, passing through the expanded clay into the bucket.
Finally, on top of this complex unit, it remains to install a computer cooler. Its task is to direct air into expanded clay nets saturated with moisture.
The final stage is also related to the operation of the cooler: it will force moisture-saturated air through the holes in the wastebaskets.

As can be seen from the above instructions, a homemade humidifier is a very real and doable task.

From the fan

Is it possible and how to make a humidifier with your own hands, if you only have a floor fan from the suitable materials available? Attach a thick, damp cloth (or even a small mat dampened with water) to the pipe. Hang this structure at a height greater than the height of the floor fan. It can be a floor lamp, a stable stick, etc. Install a fan directly behind the fabric structure and turn it on. This moisturizing technique isn't very effective, and you'll have to constantly make sure that the cloth or mat stays damp all the time.

Incidentally, the same principle applies to incubator humidifier made by hand. Amateur poultry farmers adapt a moistened cloth or large sponge and create an air flow that enhances evaporation. Sometimes it turns out to be quite an effective method and natural evaporation water from pre-prepared baths.

Antibacterial humidifier from a plastic container

If you set yourself the task of not only slightly moistening the air, but also holding it basic cleaning We recommend using this method.

To make the device you will need:

Plastic container;
fan with low speed;
filter with disinfectant (antibacterial) properties.

Note that an ordinary moisturizing sponge impregnated with an antibacterial agent can act as a filter.

Thanks to the pores, it can easily retain animal hair, hair, large dust particles. Antibacterial impregnation, in turn, provides disinfection.

The following instructions will help you assemble a humidifier and air purifier with your own hands:

Take a plastic container (box) and make a cutout on the side. The height of the cutout is approximately ½ of the height of the filter itself.
Fasten the filter with plastic ties.
Next, we form a cutout in the container lid. The size of the cutout depends on the size of the fan.
Attach the fan to the top of the tank.
We pour water into the structure. The water level must not reach the point where the cutout for the filter on the side of the box begins, otherwise leakage may occur.
We turn on the fan.
The filter must be changed periodically. If you notice that the sponge has darkened, most likely you should replace it with a new one.

ultrasonic humidifier

If you decide to make an ultrasonic humidifier with your own hands, then for this you will have to stock up on a few more special devices. So, you will need:

ultrasonic steam generator (piezoelectric element);
computer cooler;
plastic tank up to 10 l;
Cup;
power unit;
any flexible pipe, preferably corrugated;
stabilizer;
an integral part of a baby toy (pyramid) in the form of a donut;
aluminum corner.

The final cost of all assembly parts will not exceed 1000 rubles, which is much more profitable compared to a "store" humidifier. So, let's start creating the structure:

We drill holes in the lid of our plastic container with a drill. Keep an eye on the diameter of the holes obtained: in the future, fasteners from the cooler-fan, an output flexible tube and wires of the ultrasonic piezoceramic steam generator element will be inserted there.
Screw the fan to the tank and insert the corrugated pipe into the prepared hole.
The steam generator needs to stay on some kind of surface. To do this, we will make a platform floating in the container, on which we will install the steam generator. The platform can be built from a dimensional plastic cup and a donut from a children's pyramid. Place the cup in the bagel, making a small hole in the bottom of the cup beforehand. Attach a piece to the bottom with an elastic band thick fabric- it will act as a filter.
Install the UV converter in the beaker.
This device operates on the basis of direct current voltage 24 V. For normal operation of the fan, 12 V is sufficient, so the power supply can be regulated thanks to the stabilizer microcircuit.

This model of humidifier requires the constant presence of water in the tank. Also make sure that the water is distilled, otherwise the device will quickly fail, scale will appear.

Conclusion

Creating a humidifier at home is not at all difficult, and sometimes very exciting. This will save a lot of money, as well as develop the skills of a novice master. And the final effect of do-it-yourself humidifiers is sometimes not inferior in quality to factory models of famous manufacturers.

Among a large family of such equipment, it is always popular with most users. The increase in air humidity occurs due to the spraying of the smallest particles of water using an ultrasonic plate. It is because of this that a particularly fine water mist is obtained, without heating the surrounding air. Moisture particles dispersed in the air are so small that they do not settle under the influence of gravity, but are retained by the molecules of the air mixture until they are completely dissolved.

In this article, you will learn how an ultrasonic humidifier works, its device, as well as the advantages and disadvantages of a climate device.

The device and principle of operation of the humidifier

The climatic device consists of a container, in which the main supply of water is located, and the base of the device, with an emitter located in it. A metering valve is installed in the main water supply tank, which serves to maintain the desired water level in the compartment with the emitter, preventing excess. In addition, a fan is installed in the humidifier to blow out the water sprayed by the ultrasonic element.

Almost every modern humidifier has an electronic control, and a hygrostat, to accurately measure the level of humidity. Many manufacturers equip their devices with ionizers, different system filtering and many additional programs for more comfortable use of the device.

The principle of operation of an ultrasonic humidifier is easy to understand.

The main unit of the device is the emitter. It looks like a washer made of piezoceramic ceramics, with silver-plated electrodes brought out.
When an alternating current is applied to it, this element begins to vibrate at an ultrasonic frequency. When a certain power is reached, the oscillation speed increases to such an extent that it begins to break the surface of the water into tiny particles.
The water turned into an aerosol by the emitter in the chamber above the ultrasonic element is blown out by an installed fan. The water mist fills the room and raises the level of air humidity up to the limits set by the user.
The hygrometer installed in the appliance will show relative humidity air, and the user always has the opportunity to stop the device from running the program or increase the power of the humidifier in case of insufficient humidity.
After the device reaches the desired humidity values, it stops and is in standby mode. After the moisture content in the room air decreases, the device switches on automatically and the cycle repeats.

Features of some models, advantages and disadvantages of devices

Fully automatic devices have sensors that independently carry out indoors and select the desired program of work to achieve the maximum level of comfort.
Some models are equipped with an air filtration system, which significantly reduces the amount of dust in the surrounding air.
Many companies equip their appliances with effective water filters, thanks to which the salt content is significantly reduced and tap water can be used in the appliance.

Ultrasonic humidifiers have undeniable advantages that deserve respect:

Spraying water into the mist.
air humidity.
Low noise level.
Compact and ergonomic.

But this climate control equipment also has disadvantages. Many people ask if an ultrasonic humidifier is harmful. It is impossible to answer this question unambiguously, since the main “disease” of these devices is the presence in the air, and then on household items white plaque. And the white coating is the salts in the water. When the "fog" evaporates from the air, salts fall on the floor and furniture in the room.

The emitter itself does not bring any harm to the health and well-being of humans and domestic animals, but the salt precipitate, along with air flows, is inhaled into the lungs. A healthy person will not even notice this, but an asthmatic or a person suffering from certain types of allergies may feel a deterioration in well-being, up to the onset of seizures.

In general, a humidifier is a very useful device, especially in. Thanks to this device, a person's breathing becomes deeper, which means that the blood is more saturated with oxygen and nourishes the brain and all organs. Sleep becomes stronger and deeper, a person rests better in a humidified room. In addition, the nasopharyngeal mucosa does not dry out, which is very important for people with respiratory problems and snorers.

Many people, especially before the appearance of a child in the family, are faced with a difficult task and ask the question of how to choose an ultrasonic humidifier. There are several main criteria for choosing humidifiers:

The main criterion in choosing this climate device is its autonomy, so you should choose a device with a large volume of water tank.
The power of the device is also important. Why inexpensive and beautiful equipment that will not cope with the tasks.
Choose a device with the lowest noise level. In the store, it may seem to you that it is completely inaudible, but at night the noise will definitely appear and will interfere with normal sleep.
Pay attention to models equipped with a water filtration system to avoid white deposits in the room.

Advice:
When choosing suitable model humidifier, first of all, you should pay attention to user reviews of certain models. Here you can definitely find out all the advantages and disadvantages of this model.

The need for this climate equipment in our homes is obvious. Normal favorably affects the respiratory system and the general condition of the body, as well as the skin and mucous membranes. Buying a humidifier, you make the most favorable microclimate in your home.

My air humidifier also recently broke down, without which I can’t exist normally at all. The problem was in the air intake filter, it clogged. I decided to buy a new filter, since it is very cheap, I installed it in a humidifier. Imagine my surprise when everything worked again. Frankly, I until the end believed that the problem was a malfunction of the emitter, but after I read the article, I immediately found the cause of the breakdown.

Pavel Sofikatov

I have a humidifier in the children's room. It recently broke down. At first I wanted to take it in for repair, but then I decided to figure out what was the matter myself. The emitter worked, there was a characteristic "gurgling", the generator felt, it was warm. Also checked the piezoelectric element. It also functioned well. But for some reason there was no pair. Here I got confused, as the humidifier fan was working properly. The air intake filter was clogged. I ordered a new filter. Replaced, now everything works.

Zakhar

My humidifier has not yet broken, but, in which case, I will try to repair it myself too. I think it will work.

Artem

I have been using my humidifier for about a year now, but since I regularly clean it and also change the water in it, so far, thank God, there have been no problems with it.

Egor Matveev

In the office in winter, we heat up with fan heaters, and they “dry” all the air, so we constantly use a humidifier. It works throughout the day and therefore breaks down over time. After an expensive repair, I decided to try to repair it myself. After a long disassembly and checking the performance of all parts, it became clear that the breakdown was in the piezoelectric element. I ordered it online and replaced it. I did everything myself, but it took a lot of time. Therefore, next time I'd better give it to the workshop, it will turn out more expensive but much faster. Although, if someone has a lot of free time, then you can do it yourself.

Ivan

In my humidifier, the vaporization at first slightly weakened, I did not attach any importance to this, after a couple of days the steam stopped flowing completely. I thought it was a generator, I checked it, as it was written for you on heating the radiator, thank God it worked out .. As a result, I determined that it was a piezoelectric element, opened the device, photographed the wires and wrote down their location. Now the most difficult thing is to find a replacement part ... Radio shops are not a frequent occurrence in our city, I haven’t found it on the iron market, I’ll probably have to really look in online stores, although I don’t want to wait at all, we use the device every day.

Roma

And I completely dismantled my ultrasonic humidifier to the screw. I checked every detail in the same order as I disassembled it. Do not believe me, I did everything except checking the voltage on the turbine windings (((. I took it to a service center, they did it for me in one day. Recently, my wife began to complain about the smell of rot from the humidifier. I bought a new one, the old one lay until today until I came across this article. As the saying goes: “Everything ingenious is simple.” Now we have two ultrasonic humidifiers, we will be healthier :)

Paul

but my humidifier works intermittently, then it gurgles weakly, then strongly. that with him xs it is necessary to measure the voltage on the element.

Oleg

Tell me, I have a Rainbow humidifier, in my opinion it is not ultrasonic. Everything works, the turbine is spinning, but no steam is coming out. What is the reason?

Denis

Please tell me what could be wrong. The humidifier generates steam and everything works in it, but it overflows with water. After half an hour of work, there is a puddle under it. where to look?

Alexander

Hello! They asked to repair the POLARIS PUH5505DI humidifier. It failed after cleaning at the owners. The malfunction is as follows: when you turn on the steam, it takes about five seconds, and that's it. Press the button again, same thing. On the power supply, it was clear that there was a breakdown of the 4N65F field effect transistor. I replaced it, measured the power at the power supply connector: approximately 10 and 36 volts went out. The error remains. Membrane without damage. The transistor on the BU406 generator is good but replaced just in case. The error remains. The generator has an op-amp LM358L-replaced. Same. I measured the frequency on the contacts of the membrane with an oscilloscope - it appears for 5 seconds and everything disappears. Can you suggest what else needs to be checked. I don't want to give up.

Andrey

Good afternoon, tell me, I bought a new humidifier and it started to flow from the bottom in the off state, when it works it does not flow. How to repair this flaw?

The Russian people are very resourceful. What a person just doesn’t come up with to save the family budget.One of these inventions ishomemade humidifier.

There are some easy waysmake a humidifierwith your own hands at home. Increasing the level of humidity in the room is very important. Not required to use climatic equipment, you can be a little smart and do everything yourself.

From a bottle

You can make such a device yourself from an ordinary plastic bottle.You don't need to buy anything everything is at home.

This is the simplest method of humidifying indoor air during the cold season, when the heating season begins and the heat dries it out.

So, the easiest and easiest way to make a humidifier with your own hands:

Take a two-liter bottle of water or drink, also prepare scissors, several pieces of thick fabric, adhesive tape and gauze.
In a plastic bottle do 10 cm rectangular hole on the side. On the bottom with scissors cut through a small hole, 4 cm wide.
Use thick fabric for hanging the structure on the battery. Fasten plastic bottle to the top of the heater that goes to the radiator.
Hang it horizontallyso that the hole on the side is at the top.
The fabric will move out, so fix it with adhesive tape, put it on superglue or use tape.
Next, cut off the gauze with scissors. Width should turn out 10 cm and length 1 meter. One end of the gauze is passed through a hole in the bottom, then, through a rectangular hole on the side output to the battery. wrap her several times, again put it in water and fix it on the heater near the bottle cap.
Add water to the container and wait for the effect.

The water will take a long time to evaporate.A high degree of moisture cannot be achieved in this way.But this is the most a budget option homemade humidifier.

Can be added to water essential oils. Then the humidifier will also be a fragrance.

If the humidity in the room low , a plastic bottle will not save. In addition, you need to hang wet things or make another homemade device, which will perform a little better and suit your needs.

A fan with a humidifier is also an economical option for efficient air conditioning.

It has many advantages, including:

ease of use ;
the ability to carry throughout the apartment;
low energy consumption;
can use not only as a humidifier, but also as an aroma lamp.

Humidify the air in the apartment not difficult if a man understands such technologies.

How to make a humidifier with your own hands from a fan:

Wet the dense material with water, wring it out so that the liquid does not drip onto the floor. Hang the fabric at a height higher than the height of the floor fan. Install the last one after the material and turn it on. The fabric will have to be constantly moistened, which is not very convenient.
For the second option, you will need a cooler, old disks, a container capacity 6 liters and plastic trimmings measuring 5 by 5 cm, glue gun, a motor from a children's toy and a gear. How to make a homemade humidifier: plastic parts are needed to seal the holes on the disks, then take a tube and put the disks on it, fix them together with a glue gun. Next, you need to make holes in the container, and insert a tube with disks into them. A gear is attached to one side, and the second is fixed with washers. It remains to install the electric motor from toys and connect with gear. The manufacture of a home-made air humidifier is completed by installing the cooler in the container lid and connecting it to the network. The discs in the container are filled with water, but not completely.

That's all. If followcorrect sequencemaking a homemade fan, everything will work out.

The second version of the humidifier is more effective.

From a plastic container

Necessary. The state of health of all living people in the house depends on this. This is especially important for allergy sufferers.

You can buy, or you can do it yourself with the help of improvised means. The second option is more economical nicer admire your own invention.

This method is more difficult than a plastic bottle humidifier, but also more effective.

Procedure:

Take a mesh box, which should be slightly smaller than a regular plastic one. Attach the fishing line to the top, pull it.
Hang the cut bandages on the fishing line. Gauze should reach to the bottom and hang freely there.
Reticulate drawer installinto a large container filled with water.
Then in the lid of a large container cut through a hole in the size of the fan, which is attached there with a glue gun or double-sided tape.
It remains to turn on the fan in the network.

This design is very quiet. The fan is spinning, thus moisturizes air. Sometimes water needs to be added.

This room humidifier efficient and most importantly economical.

Ultrasonic

Ultrasonic humidifiers rightfully occupy the first place among such devices.

They are safe to use, emit little noise, have small compact dimensions, and are economical. Such devices have good performance, but are expensive in stores.

A Russian person has a very inquisitive brain, he does not want to buy expensive equipment. It's easier to save on it and do something like that device on one's own.

To make a homemade ultrasonic humidifier, you will need the following tools:

ultrasonic steam generator;
cooler with power supply;
plastic cup;
Styrofoam;
container;
corrugated tube of small diameter;
voltage transformer;
wires and plug.

A properly made humidifier will serve you faithfully for a long time. You can use it for more than one year.

It can be used in winter and summer, that is, at any time of the year when the air in the room seems too dry.

Step-by-step instruction:

In a food container do 3 holes. Their shape and size should correspond to the size of the cooler, pipe and wires that will come out of the emitter.
Fasten, output corrugated tube. All docking areas lubricate with sealant.
Wait, until the sealant dries, keep collecting the device.
Next, make a float out of foam and a plastic cup. It is needed in order to ensure the smooth operation of the humidifier due to the steam generator. in foam do hole sized for a glass and paste into it. At the bottom of the glass do the same small hole for water to flow. And to the very bottom with a glue gun attach piece of gauze. This material will serve as a filter. An emitter is placed inside.
Connect emitter to the voltage converter. All connections isolate .
Fill container with water. Put a float insideclose it tightly with a lid.

The work is over. You can use a homemade humidifier by connecting it to the mains.

From expanded clay and buckets

Expanded clay is called light porous a material that is made by firing clay or shale.

To make a homemade humidifier, you will need wastebaskets. You need to buy 2 large and 2 small ones, only they must be with holes.

You will also have to buy a large bucket of 12 liters,aquarium pump, cooler. It is necessary to rent a building hair dryer, so as not to buy or use your own for hair.

Last thing , what is needed is plastic ties.

So, how to create a homemade humidifier for an apartment:

small baskets glue upper parts. It can be done, melting plastic with a building hair dryer, use good building glue or glue gun. This will be the body of the humidifier.
In the same way fasten big trash cans.Put inside the body of small buckets. Then large containers glue .
The bottom of a large trash can cut off . Use a utility knife or scissors. In the resulting hole pour expanded clay. That is, a void is formed inside small buckets.
Next take aquarium pump and place at the bottom of a 12 liter bucket. The tubes that come from her, output to the top of the mesh baskets, where a large hole is made for falling asleep expanded clay.
Then as a lid install plastic ring.
To the top of the structure attach computer cooler. It will direct air flows into expanded clay soaked in moisture.
