How does an air ionizer work?

The basic principle of operation of all types of ionizers is the ionization of air masses under the action of high-voltage electric charges. Observation and study of physical, natural processes allowed us to conclude that the number of negative and positive ions in the atmosphere is not a constant and can change under external influence.

Most clearly this occurs during a thunderstorm. Under the influence of an electric corona discharge, neutral oxygen molecules collide with free electrons having a negative charge. As a result, an oxygen ion (aeroion) with a negative intensity is formed due to the addition of an additional electron.

Medical studies have proven that the presence of negative ions positively affects the general condition of the human body. In nature, the optimal balance of positive and negative particles is maintained naturally. Unfortunately, the general environmental situation is increasingly affecting this process.

A decrease in the concentration of free charged air ions contributes to the disruption of the biological activity of the human body and is one of the factors for the manifestation of various diseases.

Principle of operation

The principle of operation of any type of ionizer is based on the possibility of creating a stream of negatively charged particles between different polar electrodes under the influence of external energy sources. The material for the electrodes can be very different. The shape of the electrodes may also vary, depending on the design.

How does an ionizer work indoors

The flow of charged particles (electrons), formed on electrodes of negative polarity, in a collision with air molecules, forms a certain amount of negative oxygen ions.

If the speed of the electrons is high enough, then they get the opportunity to knock out additional electrons from neutral air molecules, increasing the total value of the flow moving towards the electrodes with a positive charge.

In turn, the flow of positively charged particles is attracted to the negative electrode and, when interacting with it, contributes to an increase in the number of emitted electrons. The created flows of charged particles form an electric discharge into the air.e, contributing to the continuous formation of positive and negative oxygen ions.

What variety is used in living quarters

In residential premises, ionizers are mainly used, the work of which is based on the creation of an artificial corona discharge between the electrodes, under the action of high voltage. Household ionizers are designed for a voltage of 20-30 kV. This interval allows you to create optimal conditions for the formation of a sufficient number of charged particles.

At a lower voltage, the speed and number of electrons is not able to create a sufficient potential difference of the electric field, which contributes to the creation of ions. With a voltage of more than 30 kV, there is a chance of creating spark discharges that contribute to the formation of compounds that adversely affect the human body.

Excess ozone is as harmful as its deficiency

When choosing a device for domestic use, you should focus on these indicators. The announcement of manufacturers of new developments, bipolar ionizers, or ionizers with a reduced threshold of minimum voltage, this is just a marketing ploy. There will be no benefit from such devices.

Purpose of household ionizers

All types of household ionizers are designed to create the optimal balance of negative and positively charged particles in the room, which favorably affect the course of biological processes in the human body.

Who is recommended to use air ionizers

Medical research in the field of the effect of charged air ions on the human body has proved that artificially maintaining the optimal balance of negative and positive air particles not only creates a comfortable indoor environment, but also helps to prevent and treat various diseases. According to doctors, ionizers have a positive effect on the following diseases:

  • Diseases of the upper and internal respiratory tract (runny nose, laryngitis, bronchitis).
  • Diseases associated with the cardiovascular system.
  • Different types of neurosis.

In addition to this, the use of an ionizer accelerates recovery processes in fractures and burns. It has a general anti-aging effect for the whole human body, due to the activation of biological processes.

Contraindications for the use of household ionizers

Unfortunately, the activation of biological processes in the human body does not always have a positive orientation. The use of an ionizer indoors is not recommended for acute chronic diseases accompanied by high temperature.

Malignant neoplasms exposed to charged particles activate their development. Therefore, doctors prohibit the use of ionizers for domestic purposes in cases of cancer. It is also not recommended to use the device in rooms where children can be, under the age of 3 years.

How is the air ionizer

The design of the ionizers may vary. In domestic conditions, the design developed by Chizhevsky (Chizhevsky's chandelier) is most often used. A negative electrode is one or more, combined into a single design, thin, pointed electrodes. Various objects (heating pipes, water pipes, wall fittings) can be used as a positive electrode. In principle, the positive electrode is simply connected to ground.

In modern ionizers, a grid of separate conductors is used as a positive electrode. Depending on the design, ionizers vary in power, range and purpose. As additional functions, the possibilities of humidifying indoor air, creating a directed air flow (fans), and operation mode timers can be used.
