SUNI'VLARY
A new filter, called the JOB S filter, has been
evaluated. The filter consis&s of sheets of cellulos2
wadding and corrugated papar, curved into a continuous
S shape within the cylindrical tube.
The filtration efficiency was tube same as that
of a cellulose acetate filter having a similar Pressure
drop whale its weight was 35t greater.
It showed no selective filtration for vapour
phase constituents or phenol and it reduced the
extractable nicotine level in the smoke.
ee", Subjective evaluation indicated that the smol-a
from JOB S filters was similar to that from acetate
filters.
It is not considered that this f-41 -660'r shows rauch
promise for the Australian market.
