and how they purify the air."

Effectiveness of Ozone
Effectiveness at Low Levels

In studies conducted at the Academy of Medical Sciences in Russia, Dr. Gubernskii and Dr. Dmitriev found that 0.005 ppm to 0.02 ppm of Ozone added to normal indoor air (0 ppm) increased animals' resistance to the cold, to infection, to toxic substances, and to Oxygen deprivation.

Drs. Gubernskii & Dmitriev also tested with less than 0.01 ppm Ozone in an air-conditioned office building. They also stated that : "Atmospheric Ozone has a positive effect on animals and people. 

They also stated that : "Atmospheric Ozone has a positive effect on animals and people. It is important to note its positive effect on the breathing system, blood composition, arterial pressure, immune system, general feeling of well-being, and mental and physical work capability."

Russian scientists performed a study to see how effective Ozone was at improving indoor air quality in schools. Respiratory-related illnesses were drastically improved after the Ozone systems were installed. The Ozone concentration produced by the systems were 0.015 ppm.

In testing performed by 2 scientists by the name of Elford and Van den Ende, it was found that Ozone effectively destroyed bacteria at 0.04 ppm. Many published studies show the effectiveness of Ozone (0.01 to 0.03 ppm) at removing odours and pollutants.

Safety

Professional Studies

The Refrigeration Service Engineers Society has reported that electric-arc welders exposed to Ozone levels of 0.2 to 0.3 ppm for a decade showed no adverse effects. Also, according to the 1961 Encyclopaedia of Chemical Technology,

"During the 80-year history of large scale usage of Ozone, there has never been a human death attributed to it."

To this day, there has still never been a single human death or incident of harm attributed to Ozone. 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 air purification systems are in use worldwide, both commercially and residentially. By Contrast, well over a million people are hospitalised, and well over 100,000 are killed every year due to medication side effects, according to the FDA.

Ozone is completely safe and effective when occurring within Singapore's Clean Air Act, FDA and OSHA standards of 0.05 ppm.

Self-Policing
In addition, the smell of Ozone will become unpleasant and obnoxious well before reaching harmful levels, serving as a built-in and self-policing safety mechanism. If this happens, one adjusts the equipment. However, at proper levels (0.02 ppm to 0.05 ppm), it will have a pleasant and clean smell to it, reminiscent of the smell outside after a lightning storm.

One will smell the Ozone at first, but only barely. After a day or two, you will either barely smell the Ozone, or will not smell it at all, as the pollution level in the room is minimized.
