Researchers at Linköping University in Sweden have successfully created nanofiber-based filters with an intricate network of nano-sized pores that can capture particles as small as 0.01 micrometers. These filters exhibit superior performance compared to traditional filters, effectively removing hazardous particles such as bacteria, viruses, and pollutants from the air. The nanofiber filters have the potential to be applied in various fields, including healthcare, automotive, and air purification systems, providing clean and safe air for individuals and reducing the risk of respiratory diseases.
