Ozone Air Filters

Ozone air purifiers are used to remove viruses, bacteria, mold, and other biological pollutants from the indoor air. They are also called ozone generators or ozone air filters. They have been used for decades in hospitals, the food industry, and in various medical applications.

The ozone purifiers are very good at removing odors, such as cigarette smoke and cooking odors. They become more handy when a home or any large area is flooded or has a sewage backup. This technology is often suggested by professionals and is helpful to clean up the mess. Since people and pets are removed while the ozone is applied so there is no danger of any health hazards.

Working of Ozone Purifiers
The ozone air cleaners go through a chemical process instead of electronic or mechanical processes to clean the air. Introduction of ozone into the air stream can be beneficial if used under controlled conditions and where humans are not exposed. High concentrations of ozone are effective in controlling the growth of microbes, as in meat storage, and in controlling odors, as in fire and flood damaged buildings.

Functioning & Working of Ozone
The normal oxygen is made up of two oxygen atoms. The ozone molecules are made of three oxygen atoms. The third oxygen atom in the ozone is capable to react with another molecules thus changing their chemical composition, and killing viruses and bacteria in the process. The ozone required for the killing of micro-organisms are created artificially by the ozone generators.


Ozone is not found in the air around us. It is present only at the upper atmospheric level. There are different ways by which ozone generators generate ozone. Usually it is done with some type of ultra violet (UV) lamp. However one method that needs to be avoided is the so called corona discharge systems. It convert nitrogen to airborne nitric oxide and nitric acid, both of which are harmful for the health.

Ozone Generators: Health Hazard
Instead of having all such good benefits, according to numerous ozone studies it has been proved that ozone can be harmful if used in higher concentrations. It can have adverse effects on humans health specially on the respiratory system. Many of the companies and industries, like Food and Drug Administration has therefore set a limit of 0.05 ppm.
