An inventor from China presented at the International Exhibition of Inventions of Geneva 2014 the invention: “Multilayer nanofibre filter – nanoaerosols capture and added functions”.
The invention consists of low-pressure drop filter for effective nanoaerosol filtration, VOC conversion and bacteria killing. Due to the small sizes, nanoaerosols (diesel particulates, laser-printer particles, viruses and small bacteria) can get into our respiratory, vascular, lymphatic and nervous systems, leading to various chronic diseases.
