Are ionizer air purifiers safe?

Air ionization is an effective air purification technology that can generate ozone if not properly controlled. So before buying an air ionizer, make sure it does not emit any ozone or other toxic substances!

What is ionisation?

negative ion ionisation

Ionization 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.

In the purest natural environments, large quantities of negative ions can be found. The sun's rays, the constant movement of the wind in the mountains, and the drops of water in a waterfall naturally create negative ions. They purify and refresh the air, hence the feeling of well-being you get in the mountains, in a forest, or near a river.

How does it work?

air ionisation technology

Ionisation is an air purification technology that generates large quantities of negative ions. These negative ions neutralize bacteria, viruses, dust, and particles in the indoor air. The particles are then attracted to the walls and floors, and thus eliminated from the air.

Is ionized air safe?

While air ionizers produce negative ions that are beneficial and safe for our body, why should we be suspicious of air purifiers using ionization?

The reason is that some negative ion generators emit toxic substances, such as ozone.. It is indeed extremely difficult to produce large quantities of negative ions without producing ozone.

Why is ozone dangerous? Ozone is an oxidizing gas. In very small quantities breathed for a short time, ozone is not harmful to health. However, its hyper-oxidizing action is very toxic in the long term, even in small quantities. It contributes to irritation of the membranes and mucous membranes, causing respiratory problems, coughing, and asthma.

In addition, some free radicals and reactive oxygen and nitrogen species can be generated by air ionization. The superoxide ion O2- is biologically toxic in the aqueous phase and is suspected to be involved in some cancers.

Healthy and safe air ionization!

Rest assured, the number of reactive oxygen species (including the superoxide ion) was measured at 5 cm from a TEQOYA ionizer, according to a protocol developed by the CERTAM laboratory with INSERM to measure the oxidizing potential of polluted air.

In conclusion: no ozone nor any other toxic substances are emitted. Thanks to its revolutionary and patented technology, TEQOYA develops air ionization solutions completely safe.
