Definitions
- the instant application is directed to a smoke filter for a smoking device having an element that enhances the smoke flowing thereover.
- the World Health Organization has set forth recommendations for the reduction of certain components of tobacco smoke in WHO Technical Report Series No. 951, The Scientific. Basis of Tobacco Product Regulation, World Health Organization (2008).
- the WHO recommends that certain components, such as acetaldehyde, acrolein, benzene, benzoap rene, 1,3-butadiene, and formaldehyde, among others, be reduced to a level below 125% of the median values of the data set.
- certain components such as acetaldehyde, acrolein, benzene, benzoap rene, 1,3-butadiene, and formaldehyde, among others.
- WO 2008/142420 discloses a cigarette filter where the absorbent material (e.g., activated carbon) is coated with a polymer material (e.g., 0.4-5 wt % polyethylene).
