The Korea Institute of Machinery & Materials (KIMM) has developed air purification technology to reduce ultrafine particulate matter in various public spaces, including subways, schools, department stores and other large public facilities.
The difference with its technology compared to conventional air purifiers is that it does not make use of filters, which can often become clogged and are costly to replace.
Instead, its air purification system utilises electrostatic force while minimising ozone generation.
By incorporating microfibre discharge electrodes and nonmetallic carbon plates, the system operates on a low current, yet removes more than 90% of ultrafine particles (UFPs).
UFPs – airborne particulate matter smaller than 0.1 micron in diameter – are able to penetrate deeply into the human body and have been found in the blood, brain and placenta.
Present in the air in large numbers, these particles pose a significant health risk. Research has found that exposure to PM0.1 causes...
