Making your own air purifier. Homemade air purifier from dust Powerful air purifier for the home with your own hands

If there is insufficient air humidity in the room, people feel worse. In such conditions, the throat becomes dry and the skin dries out. A cough and symptoms of a runny nose begin to appear due to the drying out of the nasopharynx and lungs, and the eyes become watery and inflamed. All this defensive reaction body to dryness and dust, which is present in large quantities with insufficient moisture levels.

Urban dust contains many harmful microorganisms, so to maintain health it is necessary to take measures to eliminate them and ensure a sufficient level of humidity. Dry air also negatively affects pets, indoor plants, wooden structures and furniture. It is also harmful to musical instruments: When wooden components dry out, they may fail.

The winter season marks the start of the switch-on period heating systems. At this time of year cold air Apartments, when heated to a certain temperature, lose humidity to a critical level.

The standard relative humidity for residential premises is defined within the range from 40 to 60%. It is necessary to adhere to these limits at any time of the year to maintain health. This is especially important if children live in the house: they have not yet fully formed immune system, so polluted dry air can cause serious illness.

In apartments with dry air, you need to regularly evaporate a certain volume of water. The best way to do this may be to use special devices - car washes airspace or humidifier . If such devices are not at hand, then you can humidify the house using other methods.

Air humidification using traditional methods

How is a humidifier useful? It provides an optimal level of moisture in the room. However, this can be done using other methods listed below. Choose one or two convenient ways. It is not recommended to apply everything at once, because this way you risk making the room damp.

If possible don't close the bathroom door, especially after water procedures. If the door to the bathroom is closed only when bathing, then moisture enters the apartment, increasing the humidity level. If you often take a bath, then after the procedure do not rush to flush hot water. Let it remain for a short time: as it cools, the water in the bath evaporates and also humidifies the atmosphere.
Dry washed clothes and towels indoors. This is also the simplest option that does not require any additional funds. Dry clothes and towels next to (and if the operating instructions allow this, then on them) with heating devices or systems: they will dry faster and at the same time release a large amount of moisture. At the same time, be careful: no traces of cleaning products should remain on things. Otherwise, you risk inhaling harmful fumes.

Evaporate the water. Place any container suitable for boiling on the stove. To do this, you need to boil water and place the container on a table or windowsill so that the vapor fills the room. There is another way: boil water and, reducing the heat to low, leave the container on the stove for prolonged evaporation. This can be done every time you cook to prevent the air in the kitchen from becoming too dry. It is also recommended to dissolve a few drops of eucalyptus oil or tea tree. Their aroma is soothing, and the vapors of these oils destroy various microorganisms and prevent the spread of viral infections, and the pleasant aroma uplifts and calms. In addition, the water can be flavored with cinnamon sticks and other aromatic herbs or spices. By the way, many are interested in Can I add it to a humidifier? essential oils. This is acceptable, but after evaporation it is recommended to thoroughly rinse the device.
Place water containers in all rooms. To do this, fill any container with water. You can decorate it beautifully so that it looks more organic in the interior, and leave it near the heaters. The water from the container gradually evaporates and humidifies the room. It is necessary to regularly change the water and rinse the containers so that harmful contaminants do not accumulate in them.
Grow house plants. Houseplants significantly improve the microclimate of the apartment. They perfectly moisturize, ionize, clean and disinfect the atmosphere in the room. Nephrolepis (house fern), Fatsia, Cyperus, Sparmania (indoor linden), ficus, dracaena, and hibiscus produce the greatest amount of moisture.

If there is insufficient humidity, people feel worse: the throat becomes dry, the skin becomes dry, a cough and symptoms of a runny nose appear.

Buy aquarium or build small fountain. These decorative components of the premises also emit a sufficient amount of moisture to humidify the premises. In addition, the aquarium and working fountain calm nervous system and create a positive atmosphere.
Regularly ventilate the premises And wet clean them. It is necessary to ventilate the apartment 2-3 times a day, even in winter period. This way you can maintain the optimal level of humidity in the rooms. ABOUT wet cleaning apartments needless to say - this is a necessary procedure.

Making your own sink

If you don’t want to use the above methods, you can make a basic humidifier and air washer from a polyethylene container and a fan.

Stores household appliances offer a wide range of air washers. However, the cost of these devices is quite high. Connectable to outlet air humidifiers can be done at home without spending a lot of money.

Materials

From polyethylene containers for 5-6 liters A simple humidifier is made. The following details need to be prepared:

computer fan;
charging the phone (at low speeds of the cooler, remove the power supply to 12 V);
stationery knife;
felt-tip pen;
moisture-absorbing microfiber cloths.

Device made of PET container and fan

Once we have all the parts, we proceed to install the device:

On the side of the container with a felt-tip pen mark installation locations cooler.

By using stationery knife make a notch for a fan.
Also make marks for slots for humidified air and holes for napkins inserted into recesses across the container.

Soldering iron according to marks burn out the exits for humid air and holes for napkins. It is better to carry out these actions outdoors, because when PET heats up or burns out, toxic fumes are released.

We attach the fan wire with a hook (loop) at the bottom. The wire is laid into the recesses in the lower part, passed through the fan fasteners and bent. Then the cooler is attached with wire. A power supply is connected to it.

On the side surfaces of napkins small slits are made for ventilation between them.

Pour water to the middle of the container and place napkins in it.

The water level in the container should be maintained and liquid added if necessary. It is necessary to change the water every day, as well as rinse containers and napkins with tap water.

You can make the device without napkins. However, when using them, the volume of evaporated moisture increases. In addition, dust will settle on the inserts: thus, the humidifier will also perform a cleaning function. To more thoroughly clean the air space, you should wrap a carbon filter in napkins, which you can purchase at home appliance stores.

Using a similar algorithm, you can make a more beautiful device using plastic container for 10 liters. In this case:

holes made for humidified air along the sides of the container,
A napkins are threaded through metal or plastic guides(wire or knitting needle) or stretched fishing line.
To reduce fan noise, you can put a porous sponge under it or pick up a cooler with bearings.

When using this device, you must constantly disinfect water, preventing the proliferation of various microorganisms. Also, for this purpose, you can dissolve some crystals of potassium permanganate in it. For this, a solution with a slight pinkish tint is sufficient.

CD device

For optimal hydration and cleansing, you can also recommend a humidifier , made with your own hands from CDs. The more disks, the wider the surface for liquid evaporation. In this case, the device performs the function of a water purifier. A significant percentage of dust settles on the discs and is washed into a tray filled with water.

You can add essential oils to the humidifier, but after evaporation it is recommended to rinse the device thoroughly.

The set of CDs should be from 50 to 80 pieces. It all depends on what kind of container for water you have provided. You need to select in advance the axis on which the disks should be mounted: it can be made of plastic or metal. You can get by with most simple option- purchase a threaded rod with a diameter of 10 mm. It is also necessary to have a supply of washers (they can be made of plastic), 2 bearings and nuts.

If you have all the materials, you can proceed directly to the installation of the device.

Using a grinding wheel, an abrasive attachment on a drill, or just sandpaper remove the top one(iridescent) disk layer so that their surface becomes porous and well wetted with water.
Thread the discs onto the pin, placing washers between them.

Secure them at the ends of the axle with nuts. When using a plastic tube, the discs are fixed with a plastic washer and an adhesive gun.
Equip the axle at the edges with bearings and secure them with nuts.
From one end of the axle install the pulley. It can be made from three prefabricated disks. The diameter of the side discs should be by 2-3 mm more than average.
On this pulley the belt is being threaded made of thin elastic.
Before final assembly of the axle with disks, you need choose a container, on which this axis will be fixed. Its length must exceed the dimensions of the container so that the bearings remain outside the boundaries of the container and rest on the built-in side squares.

It is necessary to accurately determine the location on the axis where the pulley will be fixed. It should be located opposite the motor pulley so that the belt does not slip off the pulleys.

For an impromptu wash, you can use a plastic container equipped with a computer fan. To be able to change the fan speed, you can use a television antenna power supply with a voltage regulator.

Rules for operating humidifiers

The humidifier needs to be refilled distilled water or tap water, pre-cleaned using a water filter to eliminate the accumulation of salts. If you are using the device without replaceable filters , then you need them regularly rinse. If the filters are replaceable, then they need to be done on time. change.

By using a humidifier, it is necessary to eliminate the risk of legionellosis.

When using a humidifier (except for devices where steam is released when water boils), it is necessary to eliminate the risk of legionellosis. This is an acute viral infection, which in its manifestations coincides with the flu or acute respiratory infections. It causes severe lung damage - pneumonia. It is sometimes called “Legionnaires' disease.” This pneumonia quickly develops into a complex malignant form. The infection is caused by the Legionella bacterium, which grows in a warm, humid place. The disease occurs:

when people breathe air from a clogged air conditioner (from centralized systems with air ducts in which moisture accumulates);
when inhaling moisture from public showers;
when people live or work in a room where they use humidifiers that are not cleaned, they forget to change the water in them and do not disinfect them;
when inhaling water vapor from an unclean fountain, and so on.

Therefore, the water in the device must be changed daily, and the container must be washed under the tap. In addition, the containers must be disinfected with appropriate means a couple of times a week. After disinfection, it is necessary to additionally wash the container so as not to inhale the vapors of disinfectants during operation of the device.

Price

Buy an air washer inexpensively You can find it in almost any hardware store. The cheapest options cost approximately 1500 rubles. You can also find small ones in hypermarkets or order in online stores. usb devices , which are also low cost ( from 1000 rubles).

The price of more advanced models reaches 17,000 rubles. At self-production the price of all materials will be approximately 600-1000 rubles.

Conclusion

It must be remembered that excessive room humidity ( more than 70%) poses a health hazard. Overmoistening causes mold and allergy symptoms. Everyone is familiar with the unpleasant atmosphere of dampness. Therefore, you should not overdo it with humidification of the room: maintain balance.

This video shows in detail the entire process of making an airspace wash with your own hands:

Too much dust accumulates in any room, which is absorbed by upholstered furniture, carpets, children's toys, and even by the person himself. And no matter how intensively the struggle for cleanliness is waged, dust particles will still hover in the air of the room. You can improve the confrontation process by using an air purifier. A fairly simple and highly effective device is an electrostatic air purifier.

Carbon filters for air purifier

The housing has slots for the intake of dirty air and the removal of clean air masses.
Cleansing and ionizing filter.
A dust collector consisting of installed electrodes with oppositely polar charges.
Electronic controls for automatic control.
Power supply to start the device.

Operating principle

The corona charge created on the electrode produces charged ions. As they move, they capture dust particles and bacteria. When such ions settle on the electrode, they “stick” harmful components of the air with them. Clean air is supplied back into the room. A simple working algorithm allows you to use the device in any type of room. It is suitable for small rooms whose area does not exceed 20 m2.

Advantages

Effective removal of dust particles whose size does not exceed 1 micron. Simple repairs can cause large amounts of dust to appear.
Minimum consumption electrical energy, since power modern devices does not exceed 45 W.
The installed filter does not need to be replaced. When dirty, it simply washes under running water at least once every 10 days in case of intensive use.
Models without a fan do not create sound, which allows them to be used in a child’s room or at night.

In this case, it is not at all necessary to purchase a ready-made device. You can make your own indoor air purifier with a little effort and a little time. This will ultimately result in cost savings.

DIY electrostatic air purifier: option No. 1

The design of a professional air purifier presented below allows you to determine how to install the device yourself. According to the proposed scheme, you can make the device yourself. The components of the mechanism are purchased in specialized stores, or replaced with improvised means. For example, the HEPA filter is replaced by carbon elements, the coarse filter is replaced by a porous material, and the ionizer may not be used in the design.

Do-it-yourself air washing: detailed manufacturing instructions

Diagram of a homemade purifier

This scheme works with artificial supply of polluted air. A conventional fan can be used to move air masses. By connecting such a cleaner to power, you can eliminate dust within 12 hours. But its main disadvantage is the production of ozone, which in large quantities is harmful to the human body.

Important! Using an additional filter based on activated carbon and installing a partition with silica gel will allow you to more effectively and quickly remove dust particles from the air.

DIY air purifier for home: option No. 2

Required structural elements

A small fan whose voltage is 12 V.
Power supply: Krona battery.
Terminal for connecting a power source.
Plastic container corresponding to the dimensions of the fan.
Filter element: carbon.

Manufacturing process

Cleaner in a plastic container

Apply markings on the prepared container to make holes for the entry and exit of air masses.
At the bottom of the container, apply cut lines that correspond to the dimensions of the battery.
Using a terminal, connect the fan to a power source - a battery.
Check the functionality of the assembled structure.
Install the finished structure in plastic container.
Cut the carbon filter to the size of the container.
Place the filter element on top of the fan.

Important! To increase the reliability of the design, it is better to solder the battery to the fan. This will eliminate power supply interruptions and, accordingly, increase the efficiency of using the device.

Homemade dust air purifier with humidification: design No. 3

To implement the task, the following are used:

volumetric plastic container with a lid;
12 V power supply, which can be connected to the mains;
fan of small dimensions;
filter element.

The design principle is similar to No. 2: a hole is made in the plastic tank for installing a fan and power supply. The fan is firmly fixed in the upper part of the container using bolts to prevent it from sinking into the water. Water is poured into the lower part of the plastic tank. The liquid should not reach the fan by at least 3 cm.

This device can be equipped with a relay, with which you can automatically control the structure: it will turn on and off independently after a certain time, which, you see, is very convenient.

How to make a DIY air purifier for a room with high humidity

Filters can be made from dense porous fabric

Materials needed to complete the project:

plastic container with a depth of at least 20 cm;
a low-power fan whose impeller rotates slowly;
sea or table salt;
porous material: multi-layer pillow like a cotton-gauze bandage, foam rubber;
power supply for fan operation;
fasteners;
reliable quick-fire adhesive;
sharpened knife for performing the installation process.

You can make your own air purifier by following the instructions:

make two holes in a plastic container on different walls different sizes: the hole for installing the fan must be the same size as the air exchange device. It should be placed slightly higher than the second hole on the opposite side;
fix the fan;
make a filter whose size will be slightly larger than the size of the second hole. The filter can be made using a multi-ball method: gauze + cotton wool;
fix the filter on the box using quick-drying glue;
pour dry salt so that the substance covers the hole with the installed filter, but does not reach the fan;
connect the structure to the power source and start the mechanism.

Important! When creating a purifier for an apartment with high humidity levels, you must use a fan that rotates very slowly. Otherwise, the intense air flow will “stir” the salt, which, knocking on the walls of the container, will irritate the ears. This device is not suitable for use at night.

This purifier has 2 levels of filtration: porous material in the form of gauze will eliminate dust particles; salt, which will absorb excess moisture, bacteria and fine dust. A homemade electrostatic air purifier of this type will saturate the air in the room with chlorine and sodium ions, making the indoor air more beneficial for humans and indoor plants.

The DIY purifier is made taking into account the humidity levels in the room. To measure it, a special device is used - a hygrometer. The optimal indoor humidity in accordance with GOST 30494-96 is 40-60%. If the hygrometer readings are more than 70%, a “dry” cleaner should be used. For readings less than 30%, a device with air humidification will be required.

DIY air purifier

Unfortunately, the air in our homes cannot be called perfect. Moreover, it is much cleaner outside, since it is cleaned by the sun and natural ionization, blown by the wind, and moistened by rain. But can we create such conditions in our home to purify the air? Airing and vacuuming alone will not be enough: they are not able to destroy dust and decay products: carbon monoxide, nitrogen oxides, ammonia and much more. Of course, there is a solution - buy such an air purifier device. If we talk about how an air purifier works, then everything is simple. The air in the room passes through the device, and dust, allergens, lint, tobacco smoke, and chemicals settle on its filters. Manufacturers now offer various devices: with carbon or HEPA filter, plasma, ionizing, photocatalytic and air washers.

Let’s say right away that the cost of such a device is not low. And besides, decide best cleaner air for the home is not so simple. Therefore, if you have skillful hands, we suggest you create the device yourself.

How to make an air purifier from dust?

The proposed air purifier is an air wash, where water acts as a filter, which cleans the air of allergens, dust, and dirt. As a result, the air is not only purified, but also humidified. In addition, water is the cheapest filter.

To create your own air purifier you will need:

plastic container with a lid;
fan, you can use a cooler from a computer power supply;
power supply for connecting to the network;
screws.

That's it! To enhance the effect, you can put a silver item in the water.

How to permanently get rid of annoying dust in your apartment

Every housewife at least once in her life has asked the question “how to get rid of the unfortunate dust in the apartment for a long time?” Dust particles constantly hover in the air and within half an hour after cleaning they settle on furniture and interior items. It is unlikely that it will be possible to get rid of dust in the house forever, but any housewife can reduce its amount.

Read in this article:

Eliminating dust collectors

Dust not only spoils appearance home, but also harms the health of the people living in it. Highest concentration dust occurs in the first 1.5 m above the floor level, so the child’s body suffers much more from it.

In order to eliminate dust, you need to try to get rid of its sources as much as possible.

Homemade air purifier for home

To do this:

Avoid floor and wall rugs unless you can vacuum them at least once every two days.
Give to friends or throw away items you don't use. An old coat that you have never worn, or a bag that has been hanging idle in the hallway for the third year in a row are typical dust collectors.
Reduce the quantity decorative elements in the interior. All kinds of boxes, figurines, soft toys accumulate dust and make the cleaning process more difficult. If you find it difficult to give up some mementos, hide them in a closet or behind glass.
Remove bulky curtains and replace them with more sleek ones. The best option– close the windows using horizontal blinds, which are easy to clean and do not accumulate dust.
Remove products made from natural wool, replace natural bedspreads and pillow fillings with synthetic ones.

Preventing dust

If you are wondering how to get rid of dust in your apartment, you should know that preventing dust from appearing is much easier than removing it from carpets, furniture, valuables, etc.

To ensure that dust is a rare guest in your home, you need to follow simple but effective instructions:

Ventilate the room as often as possible. In order for there to be as little dust as possible, and for all family members to have excellent health, it is necessary to refresh the air in the apartment at least every hour.
Ensure good ventilation of the premises, install a hood above gas stove. Ideally, odors from the kitchen and fumes from the bathroom should not spread throughout the house.
The temperature in the house should be maintained at 18-20 degrees. The apartment should not be too dry, but there should also not be excessive humidity.

Buy a humidifier. Don't skimp on this device. Remember that a high-quality air humidifier equipped with filters can absorb up to 75% of dust in the air.
Chemicals that are poured into air humidifiers can also be used against ticks. Attention! Chemicals against dust mites can harm some types of pets, such as amphibians and fish. Therefore, before purchasing liquid, be sure to consult a veterinarian.
Store books in cabinets behind glass.
Remember that dust mites are afraid of cold and heat. For this purpose, it is recommended to iron bed linen as often as possible with a hot iron.
Ventilate the bed fresh air. Place it outside: in summer - in sunny weather, in winter - in dry and frosty weather. Ultraviolet light destroys dust mites and decomposes their waste products, which are dangerous not only for allergy sufferers, but also for healthy people.
In order to prevent dust from entering from the street during ventilation, cover the mosquito nets with gauze soaked in water.

Systematic cleaning

Regular cleaning also helps control dust. To ensure your home literally smells clean, follow these rules:

Don't forget to wipe the dust in hard to reach places: on cornices, fireplace grates, baseboards, computer and TV screens, cabinets. At least once a month, go over the walls with a damp cloth: dust also settles on them, although it is not as noticeable as on horizontal surfaces.
Beat carpets and bedspreads at least twice a year. Together with carpets you can beat out and upholstered furniture. Fortunately, you don't have to take your sofas and armchairs outside. To prevent dust from getting into the air, before knocking out furniture, cover it with gauze soaked in water. In this case, the dust will not settle on surrounding objects, but will remain on the fabric.

If you still haven’t managed to give up your favorite curtains, provide them with proper care. It is convenient to treat curtains using a steamer. Under the influence of this device, the fabric is smoothed, dust disappears, and pathogenic bacteria die.
Pay attention to plants and pets. Veterinarians say: a pet is one of the main sources of dust in the house. Wipe your pets' paws after every walk, systematically comb the animals, regardless of the length of their fur. Wipe the leaves of the plants periodically with a damp cloth and spray with water from a spray bottle.
Wipe smooth furniture surfaces (cabinets, tables, bedside tables, etc.) with a cloth moistened with an antistatic agent. Polish with an antistatic effect is not recommended for use in homes where allergy sufferers live.

Vacuum carpets, bedspreads, floor coverings and fur products at least once a week. Open the windows wide while the vacuum cleaner is running. Unfortunately, most modern vacuum cleaners are designed in such a way that mites, sucked along with dust into the vacuum cleaner pipe, are immediately thrown back through the outlet.
In order to rid your home of dust mites, buy special filters for your vacuum cleaner, for example, HEPA. A good purchase would also be washing vacuum cleaner with aquafilter.

Helpers in the fight against dust

They will help you get rid of dust in your apartment. special devices and products that can be bought at any store. These include:

Humidifier

In a room with humidified air, it is much easier to combat dust. Dust stops flying randomly in the air and settles on the floor and furniture, where it can be quickly removed with a rag or vacuum cleaner.

Vacuum cleaner

A vacuum cleaner with an aqua filter will allow you to remove dust not only from the surface being treated, but also from the air. Thanks to a good vacuum cleaner, a dust-free room will sparkle with new colors.

Chlorophytum

A plant that, according to knowledgeable people, can reduce the amount of dust in the room.

Hygrometer

A hygrometer is used to monitor the humidity in the home. If the humidity level is exceeded, ordinary household dust can turn into a dangerous reagent, not to mention the appearance of mold.

Membranes for windows

Devices that protect your home from dust particles and dangerous allergens entering it from the street. High-quality window membranes prevent bacteria, pollen, smog, insects, mold, etc. from entering your home.

"Air wash"

A modern device that passes all the air in the room through itself and cleans it of dust particles. “Air washing” is especially effective in homes where dust is difficult to get rid of using available means, for example, in recently renovated premises and new buildings.

When choosing an “air washer”, pay attention to the area of the room and the goals you set for yourself.

So, some devices effectively humidify the air, others help get rid of bacteria and unpleasant odors, still others ionize the air in the apartment and disinfect it. If you want to get rid of dust, it is recommended to buy those “washers” that effectively cope with the tasks of purifying and humidifying the air.

Thus, getting rid of annoying dust in the house is a rather painstaking and long process. However, following all the listed recommendations and systematic cleaning will ultimately lead you to the long-awaited result - the complete elimination of dust in the apartment.

How to choose air purifiers for an apartment

How to choose the best air purifier for your apartment, an air purifier can ensure the cleanliness and safety of the air space.

The air in cities is far from perfect. And you shouldn’t think that those who have installed an air heating system combined with ventilation in their cottage are safe.

There are only a couple of coarse filters, as well as a primitive air humidifier, but today we are going to talk about more powerful devices that can even remove germs from rooms.

If someone in the family is sick, or there is a bad smell, you can try to fix this. It is unlikely that you will be able to make an air purifier yourself from scratch, but you can certainly buy a suitable one in a store.

We apologize in advance for the fact that we will talk about a variety of devices from the class household equipment. The fact is that many of them simultaneously purify the air.

Look at what exactly should be included in this concept. Look and choose. Perhaps you won’t spend money on an air purifier, then take a device with combined functions. Let's start with a very original type of humidifier.

There are two types of vacuum cleaners that can serve as an air purifier:

Vacuum cleaners with aquafilter.
Washing vacuum cleaners.

Essentially the principle of their operation is similar. And it’s probably not difficult to guess how these devices turn into an air purifier. We have already described the principle of operation of a cold evaporation humidifier. Vacuum cleaners are not much different, the essence is the same. Air is sucked in, passes through the water in one form or another, and then thrown out through at least two filters. We can say that it will come out cleaner than from a humidifier and will contain no less water vapor.

The operating principle of an improvised air purifier is quite simple. At the entrance to the vacuum cleaner body there are several nozzles located around the channel. Each one throws out a stream of water that washes the incoming stream. In normal mode, it is assumed that there is a lot of dirt and debris, but if you use a vacuum cleaner as an air purifier, then there will be much less foreign matter.

You can make an air purifier with your own hands from any vacuum cleaner with an aqua filter. To do this, fill the tank with water. Turn on the device and leave it for half an hour with the brush hanging in the air. This is how a vacuum cleaner for cleaning an apartment turns into a hybrid household appliances- air purifier + humidifier. There are two disadvantages to this solution to the problem:

Vacuum cleaners are very noisy. A conventional air purifier operates at a volume of 53 dB (at maximum power), while a vacuum cleaner exceeds this figure significantly.
The power consumption will leave much to be desired, since the vacuum cleaner is not directly designed to clean the air.

In this case, the quality of cleaning will undoubtedly be better than in the case of the humidifier described above. The fact is that many vacuum cleaners have HEPA filters installed at the outlet. This ensures that the flow is free of particles of the order of several microns in an amount of over 99%. However, specialized air purifiers operate quietly, consume little energy and are able to free a room even from pathogenic bacteria.

Anyone who thinks that specialized air purifiers are not much different from a special type of kitchen hood (which does not have an air duct) is very mistaken. The difference is in purpose. A kitchen hood is designed to filter fats and odors, as well as soot. She doesn’t care about dust and pathogenic bacteria, although large particles will certainly remain inside.

Therefore, take note: a kitchen hood can serve as a primitive air purifier. But only those models that work on the principle of recirculation (that is, they throw air back into the kitchen). We have already mentioned that such devices get rid of soot, fats and odors.

What exactly will settle inside depends on the type of filter installed. It is possible to create an air purifier from a kitchen hood, but it will not be very effective.

We have already given quite a lot of arguments that should make it clear that a specialized device is needed to perform the procedure. And it exists. Most of all, an air purifier resembles a leaf blower. But the passing flow does not heat up, perhaps just a little.

On the opposite sides of the case there are two sets of slots, entrance and exit. The fan located inside actively throws air out, so the flow from the opposite side comes inward.

Cleaning is done by filters, and there are usually several modifications. The first stage is quite rough, traps dust, pollen, hair, and animal fur. This element needs to be changed periodically, and it does not deserve special attention. Much more interesting is what is located further into the air purifier.

Many commercials describe this in general terms. For example, moisturizing and deodorizing filters. The first saturates the air with water vapor, the second cleans the flow of odors. Next comes another stage, which actively fights bacteria.

Such an air purifier may contain green tea extract, hypoallergenic and bactericidal components. It is believed that not only particles larger than 0.1 microns remain inside, but also pathogenic bacteria.

To produce a simple cleaning device with a carbon filter, you will need to stock up on:

miniature fan operating at 12 V;
Krona battery and terminal for it;
a plastic box, the size of which will allow you to install a fan inside it;
carbon filter.

The box will serve as the body. A fan is needed to circulate the air mass being purified; a battery is required to power the cooler. This means that holes need to be made on the housing to connect the battery and to ensure free flow of air to the carbon filter, the flow of which will stimulate the fan.

Marker on plastic box Let's mark the lines of future cuts for the intake and exhaust of purified air on the lid and bottom, for connecting the supply element in the center of the bottom edge.

Carefully saw holes along the marked lines.

The battery will be connected to the fan using a terminal. It is better to use solder to increase the reliability of contact.

The terminal must be glued to the fan, and then the functionality of the created “node” must be checked.

So the homemade air purifier is ready, the assembly of which took a minimum of time and no special money or effort was spent.

How to make a purifier with a humidifier

The construction principle is similar. You will just need a larger container, in which a hole will need to be made only for the fan and the power source. You also need to cut holes for the bolts, with which you need to fix the fan in the area of the upper plane homemade device.

Bottom part The purifier will fill with water. Instead of a battery, you can use a 12-volt power supply, which will allow you to connect the device to a landline network. If the water in the cleaning device is enriched sea salt, the air in the room will also be ionized and saturated with useful molecules.

Focusing on those already introduced into production technical developments, it is quite possible to make any device with your own hands. Super difficult to homemade devices There is nothing to clean the air. Everything is based on the competent application of the laws of physics, diligence, hard work and the ability to use tools.

Human health directly depends on the air that enters the lungs. There are soaring in the atmosphere chemical elements due to emissions from enterprises, transport and other sources of pollution. To breathe clean air, you can buy an air purifier for your home or make one yourself.

All cleaners work the same. They clean the air from small dust particles. They use a filter through which polluted air passes. After filtration, the fan blows clean air out.

Popular filters:

aquatic,
electrostatic,
coal.

Having two options, buy a device or build it yourself, let’s consider the second of them. You won’t be able to make a multifunctional purifier at home, but you can build simple model Can.

Options for homemade devices

Before designing a purifier, it is worth considering climatic conditions in the room where it will be used. For example, for a room with normal humidity but a lot of dust, a purifier can be used, for the manufacture of which you can take a filter from a car.

Devices for dry rooms

In rooms with dry air, the purifier has an additional task of humidification. For humans, comfortable humidity is 40–60%.

Even a beginner can build a homemade purifier. For this you need a plastic container and a computer cooler. The action plan will be like this:

Cut two holes in a plastic container. They are needed for the fan and the outlet of purified air.
Screw the cooler to the lid of the plastic container. Self-tapping screws are suitable for this.
Connect the fan to the power supply. You can use a 5V or 12V unit. The greater the power of the unit, the higher the speed will be. The efficiency of the unit depends on this.
Place microfiber cloth pieces inside the container. It can be replaced with any fabric with high density. To place them inside the cleaner, stretch the fishing line in several rows.
Place the fabric so that it does not touch the sides of the container. This is necessary for free movement of air to the outlet. As air passes through the purifier, dust will remain on the damp cloth. To increase cleaning efficiency, make additional holes on the side walls of the container above the water level to hang the fabric.

Devices for wet rooms

Premises with high level humidity brings inconvenience to its owners. This is a breeding ground for microbes, fungi and bacteria. High humidity air damages property. This is especially true for furniture. To combat this problem, you need a device that will dry the air. Here you need regular table salt.

Before using salt, dry it in the oven. This will help her fully fulfill her functions.

When constructing a purifier for drying and purifying air, use the same instructions as when constructing a purifier for dry rooms. With the exception of the fan, the power of which should be 5V. Otherwise, the salt will scatter throughout the container. Change the water to a 3–4 cm layer of salt.

You can increase the efficiency of the cleaner by replacing the salt with silica gel. It absorbs moisture better. Silica gel is non-toxic. This substance can be found in shoe boxes.

Use silica gel carefully if there is a child in the house. The baby may be poisoned by the substance.

Silica gel is distributed by Chinese online stores in a variety of packaging. The main advantage is using a small amount to get the same effect.

Silica gel is colored in blue, which works as an indicator. The substance changes color to pink when the amount of moisture reaches its maximum. Crystals can be reused. To do this, silica gel is dried in microwave oven for eight minutes. The power of the microwave oven during drying should be minimal.

Device with carbon filter

In rooms with the smell of cigarette smoke, activated carbon is used as a filter. It removes from the air toxic substances. To make an air purifier with your own hands, follow the algorithm:

Trim sewer pipe 200 mm to 77 mm. A pipe that is inserted inside measuring 150 mm should be up to 75 mm. Remove burrs from all cuts.
Point the thick side of the pipe upward. Cut the edging for maximum fit to the plug.
Do it on the inner pipe maximum quantity holes.
Make holes with a diameter of 30 mm on the outer pipe.
Don't throw away waste. These will make spacers.
Cover both pipes with agrofibre. Sew agrofibre to secure it. For reliability, use nylon thread.
Cover the outer pipe with paint mesh. Sew the mesh using two clamps.
Sew the entire length of the mesh.
Remove excess mesh and agrofibre with nippers and scissors.
Wrap the inner pipe with agrofibre, but first wrap it with metal mesh.
Secure the edges with metal tape or a blowtorch.
Insert the inner pipe into the plug and secure mineral wool or construction foam. Install the pipe strictly in the center. You can take spacers.
Install the elements of the inner pipe into the outer pipe.
Fill the filter with activated carbon. Any coal can be used.
Clean the coal from dust. To do this you need to sift it through a sieve.

Fill the coal so that no voids are formed. To fill the filter you will need 2 kg of activated carbon. To fill the structure evenly, shake it periodically.

Close the tube with coal with the adapter. The adapter will be a cover for it. Seal the resulting gap with sealant.

When the sealant is completely dry, install a duct fan into the adapter. Insert it so that air is drawn into the purifier and passes through the device, blowing back into the room. In your home, the filter can be installed in the supply ventilation duct.

To make an air purifier with your own hands, follow the presented devices. You can fill your apartment with clean air while saving money. It is enough to have primitive ones at hand building materials and the desire to make the house cleaner.

Indoor air cannot be perfectly clean. Even “harmless” furnishings can release harmful dust and toxins. The negative list will be supplemented by animal fur, the smell of failed dishes, smoke from a soldering iron... The list can be replenished endlessly, especially if ventilation does not cope well with the above points. There is a remedy - purification or filtration of the air mass, for the implementation of which it is not necessary to purchase an expensive factory device. You can make an air purifier with your own hands, saving a considerable amount to cover the urgent needs of the family budget.

You don't have to reinvent the wheel. All possible ways removal of contaminants has been thoroughly researched by manufacturers household devices cleaning. Having studied their operating principle, you can build your own useful homemade product.

The principle of air purification is to capture harmful components; industrial devices can also ionize the composition of the air mass

Purification of the air mass in the room is carried out:

Simple mechanical filtration. The action is to retain large airborne particles and animal hair. To catch them, a channel supply and exhaust ventilation equipped with a fine metal mesh.

To implement mechanical cleaning air is sucked into the device by a fan, after filtering and saturation with useful ions and moisture, it is returned to the room

Electrostatic cleaning. It works due to the attraction of particles with different charges. Positively charged dust is captured by the negatively charged plates of the device. Electrostatic filter Excellent collection of soot and dust, but does not capture organic pollutants and toxins.

Water “washing” of air. It functions by attracting negatively charged water to harmful molecules with a positive charge flying in the air.
Adsorbent cleaning. Its principle of operation is based on the ability of substances such as coal, soda, essential oils, a number of spices and herbs to absorb harmful toxic molecules through the pores. Adsorption will reduce the content of substances with a negative “aroma”, molecules carbon monoxide, nitrogen oxides and other harmful impurities in the air.

Let’s not get carried away with describing cleaning methods that allow us to get rid of microorganisms, the smallest spreaders of infections and microparticles. Similar air filtration methods are necessary in laboratories of research institutes and in surgical operating rooms. Let's consider an option that will definitely find application in everyday life.

Homemade air purifier

To produce a simple cleaning device with a carbon filter, you will need to stock up on:

miniature fan operating at 12 V;
Krona battery and terminal for it;
a plastic box, the size of which will allow you to install a fan inside it;
carbon filter.

The technician will need to buy a 12 V Krona battery, a fan, a carbon filter plate, and a plastic container for the case

Homemade manufacturing process

Using a marker on the plastic box, we will mark the lines of future cuts for the intake and exhaust of purified air on the lid and bottom, for connecting the supply element in the center of the bottom edge.

There should be a hole on the bottom edge of the plastic box for connecting the power supply

Carefully saw holes along the marked lines.

The holes on the plastic box can be cut with a jigsaw or sharp knife

The battery will be connected to the fan using a terminal. It is better to use solder to increase the reliability of contact.
The terminal must be glued to the fan, and then the functionality of the created “node” must be checked.
Having received confirmation of a correctly completed connection, we install all the elements in the housing-box.

We combine all the components of the future device - a homemade air purification device is almost ready

In accordance with the dimensions of the box, we cut out the carbon filter. It needs to be placed on top of the fan.

All that remains is to cut out the filter and install it on top of the fan

So the homemade air purifier is ready, the assembly of which took a minimum of time and no special money or effort was spent.

How to make a purifier with a humidifier

Instead of a battery, you can use a 12-volt power supply, which will allow you to connect the device to a landline network. If the water in the purifying device is enriched with sea salt, the air in the room will also be ionized and saturated with useful molecules.

Diagram and principle of operation of a factory air purification and humidification device: the water supply in the pan must be regularly replenished; special additives will be required for ionization

Focusing on technical developments already introduced into production, it is quite possible to make any device with your own hands. There is nothing super complicated about homemade air purification devices. Everything is based on the competent application of the laws of physics, diligence, hard work and the ability to use tools.
