"Please, open the window, it is very stuffy here and I have a headache", say some people. "On no account!" - say the others. "It is very cold in the street, we don't want draughts, colds, radiculitis". It is very likely that such disputes appear in any establishment, but anyway everybody fails. Why? Because the open window doesn't solve the problem of air freshness...

There is an opinion that positive ions are unhealthy. This mistake has a long history. First of all, when was discovered the advantage of ionized air, researches decided that only negative ions are useful. That's why the academician A.F.Chizhevsky began to make his lamps, and his followers - their devices - unipolar, i.e. they generated the ions of one polarity. It is easier to produce such ionizers, there is no need to think that ions can recomb

Some parts of molecules of the atmospheric air that we breathe always carry electrical charges. The process of obtaining electric charge by air molecules is called air ionization, and a charged molecule is called a light air ion, or air-ion. If a charged molecule of air settles on an water drop or a dust particle, it also obtains electric charge, and is then called a heavy "ion". There're two polarities of electricity, positive and negative, and

The majority of enterprises have been installing PCs, conditioners, make use of synthetics in decorating interior order to keep up with the modern tendencies. This leads to formation of electrostatic fields and deionization of air, to electric air imbalance. People which are long taking place in such premise, frequently feel of discomfort, closeness, weariness and decrease in concentration of attention. Under influence of conditioners and monitor

Strangely enough, we pay so much attention to what we eat, drink and at the same time we show such an insignificant interest to the air we breathe. "The air is a pasture of life", - used to say ancient doctors. The state of health of a person depends on the quality of air. But how can we determine whether the air is good or not? What is its biological and physiological importance? And how can we regulate the quality - for example, how can we crea

In our atmosphere there are quite strong electric fields. In normal conditions the ground is charged negatively, the clouds layer - positively. Normally the field is orientated from bottom to top. But it happens that the direction changes. Generally the difference of potentials is 100 volt per meter, sometimes during storms, snowstorms, dust storms it reaches 1000 volt per meter. Great changes of electric potential directly connected to meteorolo
