KMI Zeolite 1x1-4 Mesh

According to the recent American Chemical Society national meeting clinoptilolite zeolite has been used successfully to filter out carcinogenic polycyclic aromatic hydrocarbons (PAHs) in smoke by as much as 93% while maintaining the flavors.

The zeolite reduced the levels of benzo[a]pyrene, a type of PAH that the International Agency for Research on Cancer classifies as a known human carcinogen, by 93%. Concentrations of several other PAHs also dropped, many by more than 70%
