A concentric smoking filter in which one of the filter media is a fibrous tow, such as fibrous cellulose acetate tow, and one of the filter media is a web material, such as paper, is provided. The filter improves the taste, particularly, of 'ultra-light' cigarettes.

Concentric smoking filter having discrete tow and web filter media

A concentric smoking filter in which the peripheral filter medium is a fibrous tow, such as fibrous cellulose acetate tow, and the core filter medium is a web material, such as paper, loaded with carbon particles, is provided. The filter improves the taste, particularly, of 'ultra-light' cigarettes.

The calcium carbonate filler level or the basis weight of a paper wrapper for a smoking article is varied to enable the designing of smoking articles with specific characteristics including a specific puff count, tar delivery and carbon monoxide delivery.

Smoking articles using novel paper wrapper

The ash characteristics of a cigarette paper wrapper are improved by using fine particle size calcium carbonate filler. In addition, increased calcium carbonate filler loading level, increased basis weight, and various combinations of these variables are used to achieve improved ash characteristics.
