Sensor Electronic Technology, Inc. ("SETi"), the World’s first compound semiconductor for UV LED solutions (Violeds) and Seoul Viosys (KOSDAQ: 092190)’ subsidiary, announced that it launches portable air purifiers with Violeds technology, brand "VAC", to reduce infection from various harmful bacteria including new coronavirus (SARS-CoV-2) in the air. The online sales of the products will be started in both South Korea and the United States in June at first, and SETi will also continue to respond to global corporate customer’s demands and inquiries.

Violeds technology has been proven to sterilize 99.9% of new coronavirus in 30 seconds according to testing results. SETi will lead product promotion to provide consumers with quicker access to sterilization solutions until this urgent situation from the global spread of new coronavirus is stabilized. The company will continue to sell the products in cooperation with potential global partners in the future. In addition, it will expand online sales to Europe and Southest Asia in June along with new portable surface sterilizers, brand named "VSM".
The portable air purifier VAC with Violeds embedded in the air purification system sterilizes new coronavirus and various harmful bacteria. Conventional air purifiers and air conditioners collect various bacteria or viruses using only filters. Accordingly, since it couldn’t completely filter the virus out, there is a high risk of secondary air infection. However, VAC prevents harmful bacteria growing on the filter and significantly sterilizes them by irradiating the filter using Violeds’ light (photon) immediately after virus capture in the air.
HEPA filter in purification system can filter out in general fine dust and droplets more than 0.3μm but the viruses such as new coronavirus and SARS virus itself as small as 0.1μm after the droplet is dried can pass through the HEPA filter as it is.
Violeds technology provides a wide range of applications for air, water and surface sterilization, skin regeneration, insect trap and effective cultivation for horticulture.
Sensor Electronic Technology, inc. (SETi), a division of Seoul Semiconductor and Seoul Viosys, is a company based in Columbia, South Carolina, founded in 1999 by four Ph.D., for research and development of compound semiconductors in the United States. In 2005, SETi received the investment and R&D fund from Seoul Semiconductor and Seoul Viosys. For the development project, SETi is also working with the University of South Carolina and the University of California at Santa Barbara, adding depth to its research and development.
Currently, SETi is the only company in the world that can produce UV LEDs from 200nm to 430nm. To learn more, visit http://www.s-et.com/en/.
