LG Electronics, the world's leading air conditioner maker, said on Thursday that it will start selling air conditioners that prevent avian influenza with a special filter coated with a substance extracted from a fermented kimchi. The new air conditioners target Southeast Asian countries affected by bird flu and will be marketed this year. The new products, nicknamed ``Anti-A.I. Aircon,'' have a filter covered with an anti-bacterial substance extracted from kimchi, South Korea's spicy fermented cabbage dish, the company said in a press conference.
