In this project, nanofibers are produced as indoor air filter material. Nanofibers are generally fibers with diameters less than 1000 nm, produced mainly by electrospinning technology, and can be in the micrometer to nanometer pore size range, depending on the application. Nanofibers offer a very large surface-to-volume ratio, changeable surface properties and high mechanical strength of the obtained filter. Nanofiber fabrication technology can be used in various fields and has a promising future in air filter development. 

One of its biggest advantages is that it allows working with different polymers and nanomaterials. Nano additives with different properties such as carbon nanotubes, nanosilver (nAg), TiO2 can be homogeneously distributed in the nanofiber structure by adjusting the production parameters, and the nanofibers can be distributed with high surface area, fast airflow, acceptable pressure drop, controllable pore size, high mechanical strength to weight ratio, which can achieve superior functions such as thin membrane structure, improved mechanical properties, antimicrobial properties and long service life. 

The main objective of this project is to produce nanofiber filters with high adsorptive and photocatalytic activity for the removal of model bioaerosols, which include the SARS-CoV-2 virus as the main target, from indoor air and to develop the mobile air filtration systems for indoor air hygiene using nanofiber filters.
