Záchyt virů pomocí vysoce účinných vzduchových (HEPA) filtrů, potenciál filtrů založených na nanovláknech zachycovat nanočástice

Abstract

Currently, the rising demands on air filtration and safety of indoor air is documented. High Efficiency Particle Air (HEPA filters) with their 99.97% effectiveness in 0.3 nm particle size removal are widely used for indoor air quality maintenance. Recently nanofiber nonwoven materials are studied profoundly. Nanofiber-based air filters show several unique characteristics as high surface area, low pressure drop and high effectiveness of nanoparticles removal. The main aim of this paper is to discuss whether the nanofibers could be profitable in microorganism removal. Could nanofiber-based air filters replace the conventional HEPA filters? Could combination of conventional HEPA filters with nanofibers materials enhance the air filtration to remove more submicron particles?
