At present,  office automation is becoming more and more popular. Many offices have a large number of office equipment such as computers, laser printers (including copiers) and fax machines. Some of them will produce  ozone and odor during work. With the enhancement of people's awareness of environmental protection, office workers are paying more and more attention to whether the odor produced by laser printers (including copiers) equipment, including ozone, will affect health.

Laser printers use the principle of corona discharge to charge the toner cartridge and absorb the toner for imaging. During this process, the high-voltage charge ionizes the oxygen in the air to generate ozone. In the process of toner fixing, high temperature promotes the volatilization of organic components in ink and paper, resulting in total volatile organic compound (TVOC) pollution and fine particles condensed by volatile organic compounds. Due to the small size of the office, lack of air circulation, and the close distance between office workers and printers, pollutants generated during the use of printers tend to accumulate indoors, posing a certain threat to the health of office workers.
In recent years, studies have shown that laser printers are a major source of ultrafine particulate matter, ozone, and volatile organic compounds in indoor environments. Therefore, removing the ozone after the laser printer works and achieving zero ozone emission is an important part of promoting green office, and it is also an important measure to protect the health of office personnel and support environmental protection.
