Negative ions consist of air oxygen with free electron but presented with negative electric characteristics. The concentration of negative ions in air indicates the index of air clear degree.

Negative ions have direct effects to the human health like vitamins, so they are called “air vitamin”. It has excellent effects to:
·        Human breathing system
·        Heart and blood system
·        Nerve system
·        Increase metabolism
·        Improve immunity
Negative ions can be produced by thunder and lightning, photoemission, burning process, fountain wave, waterfall and other natural processes.
In nature, several processes produce negative ions to clean the air: Ocean waves, cosmic rays, plant photosynthesis, falling water and lightning. Theses highly reactive and unstable negative ions remove pollutants from the air – fine dust particles are reduced, germs are killed and allergens deactivated.
In addition, negative ions promote good health by enhancing immunity, elevating mood, improving sleep and accelerate healing.
However, in today’s urban environment, high level of pollution deplete these nature cleaners faster than Nature can produce them, resulting in air virtually devoid of negative ions. The result is a double blow to good health – heavily polluted and toxic air and minimal negative ions for our protection. Long term exposure to such air can lead to or worsen serious illnesses such as cancer, heart disease, asthma and allergies.
Firstly oxygen molecules are converted to ozone (O3) by high voltage electricity, lighting or ozone generator. 1 oxygen atom splits off from the ozone molecule and reacts with other particles when it comes within the range of a pollutant. Ozone is highly reactive, so it never fails to initiate this reaction with other particles.
As the second most powerful oxidant in existence, the single oxygen atom proceeds to “oxidize” the particle it reacts with. Meaning that it burns the particle, which changes its physical properties. In other words, the particle becomes completely harmless. When the single oxygen atom oxidizes the particle, it too is destroyed leaving behind the O2 or pure clean oxygen.

In testing performed by 2 scientists by the name of Elford and Van den Ende, it was found that Ozone effectively destroyed bacteria at 0.04ppm. Many published studies show the effectiveness of Ozone (0.01 to 0.03 ppm) at removing malodors and pollutants.
Ozone is completely safe and effective when occurring within FDA and OSHA standards of 0.05ppm.
To this day, there has still never been a single human death or incident of harm attributed to Ozone generated by ozone generators. This despite the fact that Ozone was widely used in hospitals during the first half of the 20th century and is still widely used in European hospitals.
In addition, millions of Ozone generators are in use worldwide, both commercially and residentially. By contrast, well over a million people are hospitalized, and well over 100,000 are killed every year due to medication side effects, according to FDA.
At lower levels, it can be very subtle or virtually non-existent. At these concentrations it often has a fresh and natural scent to it, much like the scent in the air after a thunderstorm. The smell of Ozone serves as an indicator of when concentrations may be approaching even minimally harmful levels. Despite the fact that most people become de-sensitized to the smell of Ozone over time, the smell of Ozone will easily give it away if it gets anywhere near 0.1ppm, since the smell would be more than over-powering. It takes long term exposure at high levels (~0.1ppm) to inflict any harm. Even if the Ozone concentration were to reach a dangerously high level, there would be plenty of time to turn off the Ozone generator and out from that area.
