With the recent sharp rise in fine dust, the need for indoor ventilation is growing. In particular, even when an air purifier is running on days with high fine-dust levels, periodic indoor ventilation is still essential, and interest in and inquiries about fine-dust insect screens have increased significantly of late.

Amid this trend, Chakhan Technology Research Institute has drawn attention by unveiling its fine-dust insect screen, 'Fine Block.' The 'Fine Block' fine-dust insect screen employs a dual hybrid filter system and was selected for the '2019 No. 1 Korean Consumer Preference Brand Grand Prize' hosted by Sports Seoul. In addition, 'Fine Block' has earned favorable reviews from consumers for its convenient one-touch design and its excellent air permeability and ventilation.

The filter of the 'Fine Block' fine-dust insect screen applies TN Nano dust-proof mesh made from the latest nanotechnology materials, recording a fine-dust filter dust-collection efficiency of 88% and an air permeability of 326. These figures exceed and satisfy the standards required by the Office of Education for fine-dust insect screens—a dust-collection efficiency of at least 85% and an air permeability of at least 250.

Furthermore, it has completely resolved the 'ventilation' problem that had plagued fine-dust insect screens and fine-dust dust-proof meshes. Existing products on the market had the drawback of poor airflow. With 'Fine Block,' on days when fine dust is not severe, the fine-dust window filter can be rolled up to allow good airflow while also preserving the lifespan of the filter.

Jeong Tae-san, CEO of Chakhan Technology Research Institute, revealed the story behind the product's development: "While running an insect-screen installation business, I received many inquiries from customers who had installed existing fine-dust dust-proof meshes and wanted to switch back to conventional insect screens because they felt stuffy from the lack of airflow in summer. So I kept wondering how I could both solve the fine-dust problem and allow good airflow, and I happened to get a great opportunity to develop it through the Incheon Youth Startup Academy program."
