Scientific Explanation
The MicroBlue™ reduced-toxicity filtration technology includes an innovative yet inexpensive material that selectively binds and inactivates many of the carcinogens in cigarette smoke. The “scavenging” activity is due to its high molecular affinity for Polycyclic Aromatic Hydrocarbons (PAHs) and other classes of carcinogens found in smoke. This intelligent and selective filtration leaves nicotine and other smoking sensations untouched. The MicroBlue™ technology is safe and does not add anything to mainstream smoke; its only effect on smoke is to selectively remove a significant amount of harmful carcinogens.
Testing Protocols
All tests conducted in ENTIRETY by accredited, internationally- recognized, independent laboratories in the US and UK.
All test samples use a standard Leading Light cigarette. Only change is the use of a MicroBlue™ filter of the same dimensions for MicroBlue™ samples. This permits a direct comparison of the relative efficacy of the filters, by keeping all else equal.
Smoke chemistry and condensate collection: ISO with 100%
vent blocking.
Base-pair DNA damage: Ames Reverse Bacterial Mutation Assay (OECD 471); TA-100 strain of Salmonella Typhimurium with S9 activation. This is the standard threshold cancer-risk assessment test used by the FDA and OECD for base-pair mutations, which are the molecular signature for tobacco-induced lung cancer.
