Air ionisation is an effective air purification technology, but it can generate ozone if it is poorly controlled. Before purchasing an air ioniser, make sure that it does not emit ozone!
Ionisation is the phenomenon of removing or adding electrical charges to an atom or molecule, which loses its electrical neutrality and becomes a negative or positive ion. Negative ions are found in large quantities in nature. The sun's rays, the constant movement of the wind in the mountains or in the trees, the drops of water from a waterfall naturally create negative ions. They purify and refresh the air, giving the impression of well-being that you feel in the mountains, in a forest or near a river.
Ionisation of the air is an air purification technique that generates large quantities of negative ions. These negative ions come into contact with pollutants, dust, fine particles in the indoor air, neutralise them, polarise them and charge them negatively. The particles are then attracted to the floor and wall walls and thus removed from the air.
While it produces negative ions that are beneficial and safe for the body, why should we be wary of air purifiers using ionisation?
The reason is that some negative ion generators emit oxidising gases. including ozone. It is indeed extremely difficult to produce large quantities of negative ions without producing ozone. Ozone is a toxic gas. In very small quantities breathed in for a short period of time, ozone is not harmful. for health. However, its hyper-oxidising action is very toxic in the long term, even in small quantities. It contributes to irritations of the membranes and mucous membranes, causing respiratory problems, coughing, diarrhoea, and asthma. In addition, certain free radicals and reactive oxygen and nitrogen species can be generated by ionisation of the air. The superoxide ion O2- is biologically toxic in the aqueous phase and is suspected of being involved in certain cancers.
Nevertheless, rest assured, the quantity of reactive oxygen species (including the superoxide ion) was measured 5 cm from a TEQOYA ioniser, according to a protocol developed by the CERTAM laboratory with INSERM to measure the oxidising potential of air. polluted.
Conclusion : no difference from "normal" air. Thanks to its revolutionary and patented technology, TEQOYA is the French specialist in air ionisation without ozone or other oxidising gases.
