Regarding the history and origin of water ozone generators and air purifiers, we can understand from the following aspects:
The concept of an ozone generator dates back to the late 19th century. In 1881, the German scientist Siemens (Siemens) first discovered the corona discharge to produce ozone method, which can be regarded as the prototype of modern ozone generator. Since then, with the development of electricity and technology, ozone generators gradually began to be used in the field of water treatment and air purification in the early 20th century.

History of air purifiers
An early form of air purifier was a protective device designed in the 1950s in response to a possible nuclear attack during the Cold War. With the increasingly serious air pollution problem, air purifiers have gradually shifted from the military field to civilian use, especially after the industrial revolution, for the removal of factory soot and pollutants, air purification technology has been rapidly developed.
Origin of water treatment ozone generator
The use of water treatment ozone generators stems from the need for water quality safety. From the end of the 19th century to the beginning of the 20th century, due to the problem of water pollution caused by industrialization and urbanization, people began to seek effective means to purify water. Ozone has strong oxidation, can effectively kill bacteria and remove organic pollutants in water, so ozone water treatment technology came into being.
Comprehensive development
With the continuous advancement of technology, ozone generators and air purifiers are becoming more and more efficient, safe, and smaller, easy to use for civil and industrial use. By the 21st century, these devices have become an integral part of public health, environmental protection, food processing and many other fields.
