Introduction

 

Most of the air purification systems are unhealthy due to the fact that :

  • they store and release micro-organisms
  • their mechanical filters neutralize the negative air ions

Our air purification concepts are based on the natural air purification process of the earth that is initiated by the 2000 flashes of lightning that are generated per second in our atmosphere.

 

Lightning generates in the air high concentrations of negative and positive air ions and micro-concentrations of ozone O3. Due to the high voltage generated in the air, some air molecules, like CO2, H2O and N2, tend to loose one electron, building positive air ions (PAIs) and oxygen molecules tend to capture one electron, building superoxide ions, O2-, also called negative air ions (NAI).
 
 
Thanks to the generation of air ions, all the matters suspended in the air, like particles, aerosols, micro-organisms, viruses & allergen, start aggregating and sedimenting on the floor and on surfaces. High concentrations of NAIs have a bacteriostatic effect (see Air Ionisation)

 

Thanks to the chemical reactions between the air ions and the micro-concentration ozone, the air becomes bactericidal ; it can consequently not only kill the micro-organisms but also oxidise the volatile molecules. Tanimura & al. (1999) and Fan & al (2002) have confirmed this natural phenomenon scientifically.

 

This lightning effect can be technologically reproduced by:

  • the combination of an electrofilter with negative air ion generators (EFIS concept)
  • bipolar ionization lamps

After a thunderstorm, this high air ion concentration helps us to “deeper” breath and the micro-concentration ozone gives a feeling of air freshness.

 

Nearby a waterfall or in the mountain, the air has a higher concentration of Negative Air Ions that have several positive impacts on human health like:

  • activation & regulation of our vital functions like our immune and hormonal system
  • blood oxygen concentration increase and blood fluidization
  • better psychological heath, feeling of wellbeing
