SETi releasing Violeds-based portable air purifiers for coronavirus disinfection
Sensor Electronics Technology Inc (SETi) of Columbia, SC, USA – a division of South Korean LED maker Seoul Semiconductor and UV LED product maker Seoul Viosys Co Ltd (SVC) that makes UV-A, UV-B and UV-C deep-ultraviolet LEDs (emitting at wavelengths of 200-430nm) – has launched portable air purifiers with Violeds technology (branded VAC) to reduce infection from various harmful bacteria as well as the SARS-CoV-2 coronavirus in the air.
HEPA filters in a conventional purification system can filter out fine dust and droplets measuring more than 0.3μm, but viruses such as the new coronavirus and SARS virus (as small as 0.1μm, after the droplet is dried) can pass through the HEPA filter as is.
Violeds technology has been proven to sterilize 99.9% of new coronavirus in 30 seconds, according to testing results.
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 so, since they can’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 immediately after virus capture in the air.
Online sales of VAC will commence in June in both South Korea and the USA initially, and SETi will also continue to respond to global corporate customer’s demands and inquiries. SETi says that it will lead product promotion to provide consumers with quicker access to sterilization solutions until the urgent situation from the global spread of the new coronavirus is stabilized. It 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 branded VSM.
