| We will see the evolution of the Home Air Purifier, as | | | | naturally for a specific purpose, but as they say "too |
| some call it. And I want to also mention that the | | | | much of a good thing, is not good". One thing about |
| term air purifier has been abused. Many claim to sell | | | | ozone generators, is that they pretty much cover |
| the best air purifiers when in essence they're only air | | | | the whole area they're in. Air purifier? Not quite. |

| An air filter is a device made to draw air through | | | | of the air purifier , It started when NASA needed to |
| filters, made up of different materials, to capture | | | | remove chemical pollutants from within the space |
| particles in the air. There are still quite a few of these | | | | shuttle during it's mission trips. The solution |

| different, more sophisticated filters such as charcoal, | | | | causes a reaction on titanium dioxide, which in turn |
| activated carbon or Hepa. This new filters have | | | | would create oxidizers that dissolved pollutants and |
| better absorption of particles and some chemicals, | | | | turn them into water vapor. That evolved into what |
| but they are still filters that you have to replace | | | | is called Photohydroionization a process much like |
| periodically. Now, how much of the air in your home, | | | | Photo-Catalytic Oxidation, but this time the UV light |
| do you think the device can circulate through? The | | | | causes a reaction on different metals, that create |

| the air in your home. What about the rest of the | | | | But even that has evolved to what is now known as |
| stagnant air in your home? Keep that in mind. | | | | Radiant Catalytic Ionization. This process uses a UV |
| Then we have the electric air filter or electrostatic | | | | light and a rare metal hydrophylic coating to produce |
| precipitator, which I call the 1st generation ionizer. | | | | hydroxyls (combined water and oxygen particles) |
| This unit used negative ions to attract particles in the | | | | that acts like a purifying plasma to scrub the air. It |
| air to anything below. That idea evolved, and now | | | | also duplicates ionization (electrically charged particles |
| uses positive ions to attract particles in the air to the | | | | generated in a thunderstorm) and oxygenation (the |
| negative collector plates in the unit, thus collecting | | | | oxygen saturation of air to purify contaminants) that |

| Is this an Air purifier? I don't think so, the plates need | | | | air. This technology has the three steps process to |
| constant maintenance, because when the plates are | | | | clean indoor air, ionization (removes particles from |
| covered with particles, they no longer catch the | | | | your breathing space), oxygenation (removes odors) |
| particles, they just go by. And again, how much air | | | | and irradiation (kills germs and bacteria). The purifying |

| Along came the ozone generators, that use ozone to | | | | nook and cranny it can find, killing germs, bacteria and |
| clean the air. They tried to duplicate what nature | | | | viruses on every surface giving you complete |
