Air pollution is often related to increased concentration of particulate matter 2.5 (PM2.5)
pollutant particles in the air. One of the methods of their removal is air filtration. Hereby, a
novel and simple method of producing nanofiber-based air filters with multiple active
components for highly efficient PM2.5 capture is proposed. Micro-porous carbon nanofibers
(MCNFs) were produced by carbonizing electrospun polyacrylonitrile (PAN) polymer and
was later incorporated into the nanofibrous structure of the filters, which itself was made
from electrospun PAN, achieving the production of two active components of the filter from
one starting material, simplifying the production process. When compared to the base PAN
filter, PAN/MCNFs filter exhibits greater filtering properties with almost absolute pollutant
particle removal. Their improved thermal and mechanical properties make this kind of filters
suitable for harsh-condition environments, such as those in industrial plants. The possibility
of using studied filters in facemask production was studied and reduced temperature
variation was recorded when using a facemask with an inserted PAN/MCNFs filter, thus
increasing wearing comfort for the user. All mentioned properties open a potential possibility
for these filters to be used in different environments, but also leave room for further
improvement
