Hanwha L&C held a donation event for its Dust Jam fine-dust-reducing insect screens at Kyunghee Middle School in Dongdaemun-gu, Seoul, on June 30. In an industry first for the window and door sector, the company donated 144 sets of fine-dust-reducing insect screens to an educational institution free of charge to help improve children's learning environment.
Dust Jam, whose name means "putting dust to sleep," is a hybrid dust-proof insect screen that attaches countless nanofibers between the mesh to raise its fine-dust collection rate. While ordinary insect screens block only about 30% of fine dust, Dust Jam blocks up to 90% of harmful substances from outside.
In particular, the dust-proof mesh—which can be called the core technological element of Dust Jam—is a product developed through joint research with ESO I&C, a venture company specializing in advanced materials, and is notable for capturing even ultrafine dust, which is more harmful to health.
The only such dust-proof mesh in Korea to receive official certification (from the FITI Testing & Research Institute), it boasts an ultrafine-dust collection rate of about 87.5%, the highest level among products currently on the market.
Kim Kyung-pil, head of the Window & Door Business Division, said, "We hope that 'Dust Jam' can be of some small help in improving students' learning environment," adding, "Rather than stopping at a one-time event, we plan to continue developing fine-dust-reducing products tailored precisely to the school environment by reflecting the opinions of students and teachers."
