The best qualities of Ballu. Cold plasma generator Cold plasma cold plasma generator

The invention relates to the field of gas-discharge gas purification and is intended for use in residential and industrial premises.

A known installation for gas purification (RF patent No. 40013, May 31, 2004) contains a housing, inside of which there are compartments, in each of which electrodes are installed, forming discharge pairs, with one of the electrodes placed inside a layer of glass, and the second electrode made in the form of a wire mesh on which spikes are located perpendicularly.

This installation and its gas-discharge unit ensure the purification of gases and air emissions from food, industrial and other enterprises from harmful and foul-smelling gaseous substances and vapors. However, the glass for placing the electrode in it and the electrode itself have different coefficients of thermal expansion, which during operation, when increased to operating temperature and above, can lead to cracking of the insulating material and destruction of the electrode inside it, which ultimately reduces the reliability of the installation and reduces its service life services. In addition, spikes attached to the electrode mesh by resistance welding tend to detach from it when exposed to aggressive substances, which often need to be removed from the air mixture being purified. This phenomenon also leads to disruption of the device’s operating mode and a reduction in its service life.

A gas-discharge unit of a gas purification installation is known (RF patent No. 144629, 01/17/2014), containing a housing inside which there are electrodes that form discharge pairs and are made flat, while one of the electrodes placed inside the glass layer is made in the form of a flat a solid or perforated metal sheet, or from a zigzag bent metal wire, the other electrode is made of metal with slot-like holes with pins along each hole, and the body and electrodes have various protrusions, tongues, teeth and other structural elements for securing parts in the body.

The presence of a large number of different structural elements complicates the design, reduces the manufacturability of the development and reduces its reliability. The location of the metal electrode in the glass layer leads to possible cracking of the glass and destruction of the electrode when exposed to elevated temperatures, which reduces the reliability of the installation. The use of an electrode, the workpiece for which is a solid metal sheet, implies a large total surface area of ​​​​this electrode, which is under high voltage. During operation of the device, dust, suspended matter and other solid particles may be deposited on these surfaces, which causes deterioration in the operation of the device, reducing its reliability and service life. Also, with a certain composition and configuration of the dust layer, it can ignite under the influence of high-voltage discharges.

A gas-discharge unit is known (RF patent No. 2453376, 03/06/2009), taken as the closest analogue to the claimed solution, containing a housing, one electrode in the form of a glass or ceramic plate, inside which a conductor is placed in the form of a metal mesh or a metal plate with current conductor, the second electrode is made in the form of a metal mesh of wire with spikes placed perpendicularly on it, while the field of the glass plate with the current conductor placed has a polygonal or curved, for example triangular, protrusion.

The presence of a polygonal, for example triangular, protrusion, due to the removal of the non-insulated electrode from the current conductor, makes it possible to reduce the likelihood of breakdown of the plate and thereby increase the reliability of the installation. However, the use of materials with different coefficients of thermal expansion as electrode materials ultimately leads to insufficient reliability of the device and a decrease in the service life of the device. Also, the presence of spikes, as discussed above, leads to disruption of the device’s operating mode and a reduction in its service life.

The technical result of the invention is to increase the reliability of the gas purification installation by ensuring a uniform thermal and electromagnetic load on the elements of the insulated electrode during operation.

The technical result is achieved by using a cold plasma generator containing a housing, an insulated electrode in the form of a plate made of insulating material with a metal conductor and a current conductor located inside, a non-insulated electrode in the form of a metal grid located between the insulated electrodes, and the non-insulated electrode has a recess located opposite the insulated current conductor electrode, the insulating material of the insulated electrode has a coefficient of thermal expansion close to the coefficient of thermal solution of the metal conductor, the metal lattice of the bare electrode consists of horizontal wires, between which are located vertical wires with projections and depressions, and the projections of each subsequent vertical wire are located opposite the depressions of the previous vertical wire , the planes containing the protrusions of the outermost vertical wires are located at an angle of 15 to 60 degrees to the plane of the bare electrode.

The metal conductor inside the insulated electrode plate can be made in the form of a mesh or perforated grid.

The thermal expansion coefficients of the insulating plate of the insulated electrode and the metal conductor differ by no more than 20%.

The insulated electrode plate has a triangular protrusion at the top.

The recess of the non-insulated electrode can be made in its upper part and have the shape of a semicircle.

The presence of a housing, an insulated electrode in the form of a plate made of insulating material with a metal conductor and a current conductor located inside, a non-insulated electrode in the form of a metal grid located between the insulated electrodes, a recess on the non-insulated electrode located opposite the current conductor of the insulated electrode, the use of insulating material of the insulated electrode with a coefficient thermal expansion close to the thermal solution coefficient of the metal conductor, making a metal lattice of a non-insulated electrode from horizontal wires, between which there are vertical wires with protrusions and depressions alternating in adjacent vertical wires, arrangement of planes with protrusions of the outermost vertical wires at an angle of 15 to 60 degrees to the plane of the non-insulated electrode allows for uniform expansion of the insulating material of the insulated electrode and the metal conductor inside the layer of insulating material at operating temperatures, as well as uniform distribution of electrostatic and electromagnetic fields between the insulated and non-insulated electrodes, which reduces the likelihood of destruction of the elements of the insulated electrode, increasing the service life of the cold plasma generator, reliability and efficiency of its operation.

In fig. 1 shows a top view of the proposed cold plasma generator, FIG. 2 shows a side view of the inventive generator, FIG. 3 shows an insulated electrode with a metal conductor and a current conductor located inside; FIG. 4a is a front view of a bare electrode; FIG. 4b - side view of the same electrode, in Fig. 4c - top view of the same electrode.

According to FIG. 1, 2, the cold plasma generator contains a housing 1, an insulated electrode 2 in the form of a plate 3 made of insulating material with a metal conductor 4 located inside and a current conductor 5, a non-insulated electrode 6 in the form of a metal grid 7 located between the insulated electrodes 2, and the non-insulated electrode 6 has a recess 7 located opposite the current conductor 5 of the insulated electrode 2, the insulating material of the insulated electrode 3 has a coefficient of thermal expansion close to the coefficient of thermal solution of the metal conductor 4, the metal grid 8 of the non-insulated electrode 6 consists of horizontal wires 9, between which there are vertical wires 10 with protrusions 11 and depressions 12, and the protrusions 11 of each subsequent vertical wire 10 are located opposite the depressions 12 of the previous vertical wire 10, the planes containing the protrusions of the outer vertical wires 10 are located at an angle from 15 to 60 degrees to the plane of the non-insulated electrode 6.

The plate 3 of the insulated electrode 2 can be made of an insulating material having a coefficient of thermal expansion that differs from the material of the metal conductor 4 by no more than 20%. The material of the metal conductor 4 can be, for example, ferritic stainless steels. As the insulating material of the plate 3, for example, polymer compositions and compositions based on silicon and organosilicon, borosilicate Pyrex glass can be used.

A small (no more than 20%) difference in the coefficients of thermal expansion of the insulating material of the plate 3 and the metal conductor 4 leads to their almost uniform expansion, which does not allow the creation of voltages on the plate 3 that could cause cracking of the insulating material and, in general, destruction of the insulated electrode 2 when heated to operating temperature and above, which increases the service life and reliability of the proposed device.

In this case, the plate 3 of the insulated electrode 2 has a triangular protrusion in the upper part (Fig. 3). The choice of this form of plate 3 is the most technologically advanced and least material-intensive solution. At the same time, removing the bare electrode from the current conductor makes it possible to reduce the likelihood of breakdown of the plate and thereby also helps to increase the reliability of the generator.

The metal conductor 4 inside the plate 3 of the insulated electrode 2 can be made in the form of a mesh or perforated grid.

To ensure the transmission of voltage to the metal conductor 4 located inside the plate 3, the insulated electrode 2 has a current guide 5, which can be made of single-core or stranded wire, and the contact of the current guide 5 with the conductor 4 can be ensured by mechanical connection, soldering or welding.

Free from conductor 4 and current conductor 5, the field of plate 3 along its perimeter has a width X from the edge of the plate to conductor 4, ranging from 0.081 to 1 width Y of plate 3 itself (Fig. 3).

The specified range of values ​​allows the use of power sources with different output voltages for operation of the inventive device. In this case, the condition is met: the higher the voltage, the wider should be the field of the insulated electrode 2, free from conductor 4.

In fig. Figure 4 shows a non-insulated electrode in three projections. The non-insulated electrode 6 is a welded or monolithic metal grid 8, consisting of horizontal wires 9 and vertical wires 10 located between them with protrusions 11 and depressions 12. The alternation of protrusions 11 and depressions 12 are triangles, which ultimately makes it possible to obtain a zigzag shape of the vertical wire 10 (Fig. 4a). On the horizontal wire 9, the vertical wires 10 are arranged in such a way that the protrusions 11 of each subsequent vertical wire 10 are located opposite the depressions 12 of the previous vertical wire 10. In this case, when approaching the upper and lower horizontal wires 9, the height of the protrusions 11 and depressions 12 becomes smaller, that is the vertical wire 10 straightens as it approaches the horizontal wires 9 (Fig. 4b).

A metal grid 8 made of zigzag wires makes it possible to obtain the most uniform distribution of electrostatic and electromagnetic fields between insulated 2 and non-insulated electrodes 6, which in turn ensures the most stable discharges over time from the places where the wires of the metal grid 8 are bent to the insulated electrode 2, thereby increasing its resource . Due to the fact that the discharge exit points can shift slightly from the places where the wires of the metal grid 8 are bent, self-regulation of the discharge operating mode occurs, the load on the insulated electrode 2 becomes uniform over the area, which ultimately makes it possible to increase the reliability of the device.

The planes containing the projections 11 of the outermost vertical wires 10 are located at an angle from 15 to 60 degrees to the plane of the metal grating 8 (Fig. 4c).

Rotating the outermost vertical wires 10 at an angle of 15-60 degrees increases the distance from the bend points of these wires to the insulated electrodes 2, thereby reducing the load on the edges of the insulated electrodes 2, which also ensures uniform distribution of electrostatic and electromagnetic fields, increasing the reliability of the device. For this reason, the vertical wire 10 gradually straightens as it approaches the horizontal wires 9, as discussed above.

It should also be noted that all the zigzag wires in the metal lattice 8 are made identical, which makes the product easy to manufacture.

The non-insulated electrode 6 also has a recess 7, for example, of a semicircular shape, made in the upper part of the electrode 6 and located opposite the current conductor 5 of the insulated electrode 2.

Making the recess 8 in this way allows you to increase the distance from the nearest non-insulated point of the current conductor 5 to the non-insulated electrode 6, which eliminates breakdown between them, increasing the service life and reliability of the device.

Insulated electrodes 2 are installed in the generator housing 1 in the provided seats, between which non-insulated electrodes 6 are located, rigidly fastened to the housing 1, for example, by welding. Non-insulated electrodes, located at the edges of the device and having only one adjacent insulated electrode, are distant from these insulated electrodes at a distance greater than the distance between the electrodes in the center of the device.

The inventive cold plasma generator operates as follows. A gas-discharge pair is supplied to the insulated electrode 2 (via the current conductor 5 and the metal conductor 4) and the non-insulated electrode 5 high voltage with obtaining barrier discharges between them. In the gap between the zigzag metal lattice of the non-insulated electrode 6 and the surface of the plate 3 of the insulated electrode 2, an area with cold plasma is formed, which reacts with the purified gases passing between the specified electrodes 2 and 6. As a result of chemical reactions, the molecules of the purified gases are divided into active ions, free radicals with the formation of active oxygen and ozone, which enter into oxidative reactions with active ions and radicals and purify polluted gases to a harmless state.

Thus, the inventive design of a cold plasma generator makes it possible to minimize the possibility of breakdowns of the insulated electrode plate and increase the reliability of the device.

It was discovered that irradiation of cells with cold plasma leads to their regeneration and “rejuvenation”. This result, the researchers believe, can be used to develop a course of plasma therapy for non-healing wounds.

Non-healing wounds are a real problem for doctors, as they complicate even the most successful treatment. For example, when wounds occur due to vessels damaged by the disease, when and - due to suppressed immunity, and in old age the cause is low speed cell division. Treatment of such wounds with conventional methods is very problematic, and sometimes simply impossible.

It turned out that cold atmospheric pressure plasma can solve the problem. It is a partially ionized gas (the proportion of charged particles in the gas is about 1%) with a temperature below 100 thousand kelvins. Its use in the field of biology and medicine has become possible since the advent of generators producing plasma at a temperature of 30-40 °C.

PLASMA – a breakthrough into the Future from a long-forgotten past!

Yesterday I was talking to a Friend about baptism, and this is what he told me:
“Did you think you were baptized? No, you're in the water
Baptism takes place with plasma fire on Alatyr"

All night this thought haunted me... And this is what materials my knowledge led me to - Benefit or harm? It depends on whose hands the PLASMA is in - in the hands of good, or in the hands of evil.
Cold plasma: bacteria are in shock
Russian and German scientists came up with an unusual alternative to antibiotics: they showed that infection can be overcome using argon plasma, the temperature of which does not exceed 35-40 °C.
This approach made it possible to destroy 99% of microorganisms after just five minutes of processing the Petri dish: the result varied slightly depending on the type and strain of bacteria.
An experiment on rats showed that after 10 minutes, even those microorganisms that were resistant to antibiotics (Pseudomonas aeruginosa and Staphylococcus aureus) began to die on the surface of the wounds.

A five-day course led to the complete destruction of P. aeruginosa (2 days faster than in the control group). In addition, exposure to plasma accelerated wound healing in experimental animals.
Another advantage of the technique is that the stream of ionized gas can be directed only to the infected area, without affecting the surrounding tissue in any way.
The article by the study authors was published in the Journal of Medical Microbiology. The video below shows that cold plasma does not harm living tissue.
In hot plasma, matter is heated to thousands or even millions of degrees Celsius. Therefore, the concept of cold or non-thermal plasma (nonthermal plasma, the photo shows a jet) is very relative. We are, of course, not talking about freezing, but about temperatures close to room temperature. By the way, physicists learned to produce stable cold plasma not so long ago (photo from George Washington University).

Awakening (Valentyna) MEPhI scientists are developing a new way to combat pathogenic bacteria and microorganisms using cold air plasma.

Research on creating a facility capable of generating a flow of cold plasma at atmospheric pressure and room temperature is being conducted at the Department of Electrical Engineering, which is headed by Doctor of Physical and Mathematical Sciences, Professor Eduard Shkolnikov.
People have come up with all kinds of ways to fight microbes: they are fried with dry hot air in special dry-heat ovens, exterminated with superheated saturated high-pressure steam in autoclaves, poisoned with all kinds of poisons, destroyed by streams of ionizing and ultraviolet (UV) radiation. But the harmful army doesn’t care.

The figure shows an experimental setup consisting of a high-voltage pulse-periodic generator and a gas-discharge chamber

Awakening (Valentyna) Each of the listed methods has its own disadvantages. Thus, high-temperature technologies are characterized by high inertia of heating and cooling processes, the duration of the sterilization process itself and serious energy consumption. However, they do not allow sterilization of temperature-sensitive materials, because the temperature of the sterilization environment can be 150-200 degrees Celsius. Dry-heat ovens can be a fire hazard, and autoclaves do not exclude the possibility of accidental release of superheated steam. Despite the potential danger of these technologies for humans, for some viruses they may turn out to be completely harmless: for example, viruses are not always inactivated in autoclaves.
Even less effective method destruction of harmful microorganisms (albeit keeping heat-sensitive materials intact) using the so-called “cold” sterilization technology - treatment with gaseous (ethylene oxide, ozone, formalin vapor, etc.) and liquid (iodoform, hypochlorites, ethanol, compositions based on phenol, etc.) chemically active substances. All these disinfectants are very toxic and dangerous to humans. Most of them irritate the skin, eyes, and also cause corrosion of equipment and tools being processed. The “cold” disinfection procedure usually requires even more time (up to 24 hours).
The most effective way to combat a pathogenic environment is the use of ionizing radiation, in particular electronic, gamma and x-ray radiation, which ensure reliable disinfection of various, including heat-sensitive materials. This technology is implemented using electron accelerators with an energy of 2-5 MeV. However, it also has a serious drawback: the high cost of equipment and the need for specially equipped radiation-safe rooms. In addition, these installations require highly qualified maintenance personnel.
As for another ultraviolet sterilization method, UV emitters (quartz lamps) are mainly used for air disinfection, that is, they have a rather limited range of applications.

Awakening (Valentyna) Universal sterilizer

Gas discharge chamber
In recent years, the attention of researchers has been attracted by another type of weapon effective in combating pathogenic microorganisms - nonequilibrium low-temperature gas-discharge plasma.
STRF Help:
Low-temperature gas-discharge plasma contains charged (electrons and ions), neutral (atoms and molecules) particles and some active products of plasma-chemical reactions, ultraviolet and, in some cases, x-ray radiation. It is capable of oxidizing microorganisms, destroying the membranes and DNA of bacteria and viruses. While remaining cold, plasma does not destroy heat-sensitive materials, which allows it to be widely used as a universal sterilizer. Unlike traditionally used sterilization methods, gas-discharge sterilization methods based on low-temperature plasma have a number of fundamental advantages. These are, firstly, low sterilization temperatures, which makes it possible to sterilize heat-sensitive materials. Secondly, a short period of exposure to microbes. A wide range of sterilization agents that gas discharge plasma contains (charged particles, highly excited neutrals, active products of plasma-chemical reactions, ultraviolet and, in some modes, X-ray radiation) can significantly reduce the sterilization time - to several minutes. And thirdly, unlike sterilizing devices based on charged particle accelerators, plasma sterilization units are not a source of radiation hazard and do not require special premises or specially trained personnel. Other significant properties of these installations include environmental safety, low energy consumption and low cost.

Awakening (Valentyna)“Our installation,” says Eduard Shkolnikov, head of the Department of Electrical Engineering at MEPhI, “differs from its peers in two features. The first is that plasma is produced in a discharge in air at atmospheric pressure. And secondly, the structure of the discharge turns out to be voluminous and homogeneous. And this is achieved in fairly large volumes, when the interelectrode gap is 1-10 cm. In similar installations, either there is a discharge under air-atmospheric conditions, but there is no diffusion and the volumes of the interelectrode gap are small, or, conversely, there is diffusion, but gas gases are used instead of air mixtures such as helium or argon with a small amount of air. All this makes installations either expensive or ineffective. To achieve this combination, we had to do a lot of work. In particular, we created physical models, which describe discharge processes in air environments. With their help, we determined the optimal combination of such parameters of the generators powering the discharge gaps as the amplitude of the pulses, their duration and repetition rate. Experiments have shown that the discharge has a “capricious character”: if these conditions are not met, it sharply reduces the production of concentrations of the active components of plasma-chemical reactions, which sharply reduces the efficiency of the sterilization process.”
Experimental and theoretical work by researchers from the Department of Electrical Engineering at MEPhI is now in full swing. According to Eduard Shkolnikov, a prototype of such an installation will be created by the end of this year. “The task that we have set for ourselves has not yet been solved in any laboratory in the world, I can say this definitely,” says Shkolnikov. “If everything works out, it will be a good step forward.”
After creating such an installation with the necessary characteristics, doctors and microbiologists will get down to business. Their task is to test how effectively the plasma flow destroys pathogenic bacteria and microorganisms. Preliminary studies with the installation already available at MEPhI allowed us to accumulate experimental material. “I used my teaching resource,” smiles Eduard Shkolnikov. - One of our students’ parents work in a medical institution. They helped us obtain samples contaminated with Escherichia coli (E. coli). We irradiated these samples with a plasma stream and handed them back to doctors for examination. There is a result: E. coli completely decompose in a fairly short time - about a few minutes."

Awakening (Valentyna) High, even cosmic, sterility
A new high-tech cold plasma generator is eagerly awaited at the State Scientific Center of the Russian Federation - Institute of Medical and Biological Problems of the Russian Academy of Sciences. According to a study conducted by specialists from the Center for Infectious Diseases and Vaccinology at the University of Arizona, pathogenic bacteria that have been in space become more dangerous. The fact is that based on such installations, unique devices for space stations can be developed, in particular equipment for providing quarantine and microbiological safety in the living compartments of spacecraft and other pressurized spaces of long-term operation, including pressurized spaces with artificial physiologically active respiratory environments.

Homogeneous plasma flow
In addition, these installations will serve as the basis for the development of industrial low-temperature sterilizers for wide application for medical institutions, service industries of various purposes and volumes (hair salons, cinemas, cafes, restaurants), as well as residential and office premises. Today, due to the lack of such sterilization technology, medical institutions are forced to purchase expensive imported equipment, for example, a device for chemical sterilization in solutions of strong oxidizing agents STERRAD-100S (USA), which uses discharge plasma of a special solution based on hydrogen peroxide. Sterilization with its help takes one hour, while the weight of the unit is 350 kg, and its cost is 170 thousand US dollars, which most Russian clinics and hospitals cannot afford. “We want to make an inexpensive, compact device for sterilizing instruments and equip hospitals with it,” Eduard Shkolnikov shares his plans. - What is he good for? Effective, simple and safe for medical personnel.”

Awakening (Valentyna) Cold plasma against bacteriological weapons
American scientists have invented a new effective way to combat pathogenic bacteria using cold plasma. Researchers from the University of California at San Diego, together with colleagues from Old Dominion University in Virginia, claim that the new method can be used to sterilize medical devices, water, food, and as protection against biological weapons.
Plasma can contain both charged (electrons and ions) and neutral particles (atoms of chemical reagents and molecules). At atmospheric pressure, plasma most often has a high temperature (thousands of degrees Celsius) and is difficult to control, writes the journal PhysicsWeb.
Scientists were able to obtain cold plasma at room temperature and atmospheric pressure. The installation for producing plasma consists of two planar electrodes under a voltage of several kV and a frequency of 60 Hz. The space between the electrodes is filled with a gas mixture - 97% helium and 3% oxygen.
Two types of bacteria were used in the experiments - with and without an outer cell membrane. The researchers observed the processes occurring with bacteria using an electron microscope. They found that after 10 minutes in the cold plasma, the bacteria died when exposed to ultraviolet radiation and free radicals from the plasma. Moreover, scientists noticed that charged particles very quickly destroy the cell membrane - in just a few microseconds.
Scientists believe that cold plasma can become a ruthless enemy for many dangerous bacteria, leading to fatal diseases, as well as viruses.
Traditional sterilization methods, such as chlorination, are often harmful to both humans and the environment. Another method - ozonation - is also not ideal.
In addition to being expensive, its byproducts - aldehydes (formaldehydes) and ketones - also pose a danger to the Earth's atmosphere.
However, it should be noted that the use of cold plasma for sterilization is not new. In Russia and Estonia, there have been water treatment facilities using the electroplasma disinfection method for several years.

The air conditioner has a “plasma” function, how does this function affect health, and can there be any consequences, | Topic author: Arthur

with constant "plasma" mode? The air in the room has a "metallic" smell...

Gregory  This is a multi-stage air purification system that more effectively fights dust, germs and PATHENIC BACTERIA! and unpleasant odors, in addition, the plasma filter generates ions and ozone, and the fact that you smell ionized air indicates that the air conditioner is working as it should!
Another thing is that you can add a deodorizing filter there, then the smell will be different!
But in any case, this is NOT harmful; after processing, it throws into the room air enriched with ions “correct” for the body.
I GIVE AN INSTALLATION: DON’T BE AFRAID!!!

Georgy  what is it even needed for?

Arthur  I think that this name comes from the physical meaning of a substance in the state of plasma. And by this concept they mean IONIZATION of air.
This is not only NOT harmful, but also VERY useful. Be sure to use it

Plasma is a gaseous mixture of positively and negatively charged particles in such proportions that their total charge is zero. Plasma electrons and ions can carry electric charge.

Ionization is the process of formation of ions by which a neutral atom or molecule acquires an electrical charge. Typically, ionization occurs under the influence electromagnetic radiation, impacts of electrons, ions or other atoms.

So, this is the process of “demagnetizing” the air in the room. Be sure to use it

Igor  Do you like the smell of metal? If not, turn off this mode. This smell is clearly not healthy.

Air conditioning the question arises: how can one tell if the ionizer or cold plasma is working in their air conditioner, and where can these devices be found? Everyone knows where the filters are located in the air conditioner. Open the front panel indoor unit- and in front of you.

But where the “mythical” or ionizer is located remains a big question, and how they work and what the difference is between them is generally the mystery of the century. In fact, everything is simple: the ionizer and plasma generator are a block to which power is supplied and which is attached directly to the heat exchanger. In particular TOSOT The plasma generator is located in the upper right corner of the heat exchanger behind the front panel under the filter, but if they are removed, the generator can be easily found.

The question remains: how do the ionizer and cold plasma work? Let me give you a little theory.

Ionizer

Dust in the air around the ionizer is charged, forming heavy ions that are generally unfavorable to health. These charged particles move in the direction of the power lines - from the ionizer to the nearest surface (walls, floor, ceiling, batteries), depending on the location of the device. After some time, all this dust settles on the surface and you can calmly breathe air saturated with light ions.

Cold plasma

It is one of the most effective types of ionizers. Active hydrogen and oxygen ions are produced to combine with bacteria, viruses, dust and other harmful substances in the air. Bound together, they settle on the surface and are removed from the air conditioner with condensation.

Comparison table of cold plasma and ionizer

Cold plasma and the ionizer perform essentially related functions, but plasma can be called the next step in the evolution of the ionizer. It not only saturates the room air with active ions, but also removes all harmful substances from it with a high degree of purification.
