It’s no secret that in our industrial age, even air is gradually losing its natural properties. It is filled with gases and compounds that are uncharacteristic of its composition, which not only do not benefit the body, but often cause irreparable damage to it. Today, scientists and engineers come up with various ingenious devices that, when used by humans, should improve the air in cities and bring the quality of human life to a new level. One of these devices was a household air ionizer.


Unipolar ionizer: features and principle of operation

In the middle of the last century, the famous scientist A. L. Chizhevsky invented an apparatus that saturates the air with negative air ions, which he called only “air vitamins”.

Air ions are oxygen molecules that carry a positive or negative charge. Scientists have proven the positive properties of negatively charged oxygen molecules on the human body.

The first air ionizer was named «Chizhevsky’s lamp» in honor of the scientist. This device was unipolar, i.e. produced only very useful, negative air ions. On its basis, almost all household air ionizers were developed, which appeared in a huge assortment on the shelves of our stores.Chandelier Chizhevsky

Despite the widest range of such devices, they did not gain much popularity, since during the operation of the device there was a side emission of dangerous biologically active gases. Modern unipolar installations also have some disadvantages:

  • When a corona charge occurs, ozone is released into the air. This gas is quite dangerous in high concentration, so the time of using such a device must be limited.
  • Unipolar devices produce only useful, negatively charged air ions, but they form a fairly strong electrostatic background in the room. Synthetic things and the person himself acquire an electric charge.

After some time, the human body cannot absorb negatively charged air ions, since unipolar particles repel each other in nature.


Features of the bipolar ionizer

This device is devoid of such shortcomings of its monopolar counterpart. Such a device produces not only useful, but also «useless» air ions. And what then is the healing effect of such an ionizer, you ask? The thing is that in nature there are 20% more positive air ions in the composition of air masses than negative ones. Bipolar air ionizers for the home emit 27%30 more useful particles, while preventing an increase in the electrostatic background in the room.Bipolar ionizer device

Due to the carefully adjusted production of the amount of light, negatively and positively charged SanPiN ions, such a device can correct the natural imbalance and help create an atmosphere in the room that, in its composition and properties, meets all the standards–03.

Despite all the miraculous effect of the bipolar ionizer, this device does not have shortcomings that cast doubt on the need to purchase it. The thing is that, constructively, these devices cannot produce both negative and positive ions at the same time: the production of particles occurs in portions, then negative — then positive. The accumulation of particles in air masses can be represented as clouds in the sky: some are composed of negative, while others are only positive, despite their opposite charge.

In nature, all particles are mixed in air masses, as they are in constant motion. This does not happen indoors. In addition, all devices of this type distribute ions only to the distance of the air jet of the fan installed in the device. And since the fan in the device is very small, the accumulation of useful particles is located exclusively in close proximity to the ionizer.

Knowing all the advantages and disadvantages of modern devices for improving air quality, we can confidently answer the question of the majority of our compatriots: “Which air ionizer is better, unipolar or bipolar?” Bipolar is better, but with good circulation of air masses in the room with a well-organized inflow and a working natural exhaust, in other words, ventilation of the apartment. Due to this natural mixing, a balance of ions is established in the air.

DIY ionizer

This device is a high-voltage converter, consisting of a generator, a high-voltage transformer, a voltage multiplier and a power supply. We design ourselves

There are many schemes for self-creation of such a device, and any radio amateur will be able to assemble it without any problems. But the operation of the device is associated with high voltage: 6.8 kW is required for the occurrence of a corona discharge, so we strongly recommend that you do not create such devices with your own hands, in order to avoid electric shock and the possibility of fire.

If you still decide to assemble a bipolar air ionizer with your own hands, then it is best to purchase a self-assembly kit, which is available in the form of a designer. The model of such a constructor NK 292 from the company Master Kit. It can be freely purchased at specialized retail outlets or on the Internet. The cost of a set rarely exceeds 1500 rubles.
