Employing
"Nanofiber
bonded
textile
filter"
for
the
main
filter
element.
Fine
fiber
collects
the
dust,
pollen
and
also
PM2.5.
-
Preventing
the
virus
and
mold
growth
by
adding
an
antibacterial
feature
to
the
filter.
That
helps
to
maintain

What
is
Nanofiber?
A
definition
of
nanofiber
is
a
substance
that
has
a
diameter
of
1nm
to
100nm
and
a
length
of
100
times
the
diameter.
Nanofiber
filters
out
most
of
fine
particles
and
microbes
due
to
very
small
space
between
individual
fibers.
A
large
surface
area
provides
improved
absorption.
A
very
small
diameter
of
individual
fibers
significantly
improved
airflow
by
eliminating
the
vortex
generated
from
fibers
in
the
back.
