The consideration of filter density as a filter design parameter has increased in recent years. Traditional filter design is based on pressure drop or resistance to draw to achieve specified smoke filtration levels (example NFDPM). Pressure drop is...

Puff-by-puff smoke analysis has shown that the CelFX® carbon filter technology has similar nicotine and tar smoke delivery profiles but with significantly reduced carbonyls, particularly in the first 6 puffs, compared to a cellulose acetate filter....

CelFX™ carbon filter technology has been shown to reduce vapor phase smoke components by 40-90% in prior work[1]. In order to expand the understanding of this filtration performance, this work will evaluate the puff-by-puff machine profile to assess...

Previous works have evaluated cigarette filter carbon particle release from various filter designs. The recently introduced CelFX™ Matrix Technology offers high loadings of carbon, with low pressure drops and has not been studied for the particle...

Small diameter or super slim cigarettes (5.0-5.5 mm) have approximately two times the smoke velocity and about half of the filter residence time of large diameter cigarettes (7.6-7.8 mm). This limitation, coupled with lower active ingredient...

The CelFX™ advanced filtration platform utilizes a binder and activated carbon to efficiently filter cigarette smoke. Previous studies have demonstrated the role of activated carbon in reduction of many vapor phase components including various...

The CelFX™ advanced filtration platform offers a novel structure to filter cigarette smoke. The platform utilizes a special binder plus an active material to create a structure that efficiently filters cigarette smoke. Initial studies demonstrated...
