Ozone in Air Treatment
Ozone in natural settings is around 0.02 ppm, but it can be as high as 0.08 ppm. At this level it is capable of keeping pathogens in check and yet be not harmful to higher life forms such as pets, other animals or human beings. Ozone is also environment friendly. However, prolonged exposure to very unnaturally high levels of ozone may lead to discomfort, later headache and coughing. Hence, it is always advisable to use an ozone monitoring device to control the ozone level inside closed spaces to maintain ozone level in the room TO below 0.08 ppm or 80 ppb.
Air treatment with ozone is found to be very useful not only in large buildings or cinema halls with closed circuit air conditioning, but also in hotels and hospitals. Normally air conditioning ducting breeds mold and fungi and can harbour other bacteria as well due to the presence of moisture. Ozone helps in eliminating microorganisms from the ducts.
