Colored carbon on view in ‘x-ray’ filter
Filtrona Filter Products has launched a new filter that combines a colorful visual impact with the performance benefits of carbon.
Here are but a few of the studies on charcoal filters that I have come across:
Effect of charcoal-containing cigarette filters on gas phase volatile organic compounds in mainstream cigarette smoke
Overall, the brands with the most charcoal are effective at reducing VOC deliveries under even intense smoking conditions.
Charcoal cigarette filters and lung cancer risk in Aichi
The lung cancer mortality rate has been lower in Japan than in
the United States for several decades. We hypothesized that this
difference is due to the Japanese preference for cigarettes with
charcoal-containing filters, which efficiently absorb selected gas
phase components of mainstream smoke including the carcinogen
Semi-volatiles in mainstream smoke delivery from select charcoal-filtered cigarette brand variants
While charcoal-containing filters selectively removed lower molecular weight PAHs from mainstream smoke, they did not significantly remove the heavier and more toxic PAHs studied, such as benzo[a]pyrene, a known carcinogen. Likewise, charcoal-containing filters removed phenols and TSNAs from mainstream smoke to differing amounts depending on the compound, filter design and the smoking regimen.
...Which is why I always use these in addition to a charcoal filter when rolling my own. Maybe someone, somewhere will eventually getting around to doing a study on filtered cigarette holders. I have not been able to find one study anywhere, which is very strange I have to say. If tobacco control were really so concerned about the harm(s) that are inflicted upon so many by worldwide tobacco use, why are there no studies on these filters? Could they not also be part of the overall solution, which is to reduce the harms associate with smoking? Ok, we already know the answer to this question and I'm getting off topic.
I can honestly say from personal experience that my lungs are much cleaner when I wake up in the morning since I have been using them along with the charcoal filters. That has to account for something, because I can feel it. Anyway, I hope to come across one of these new filters from Filtrona because I would really like to try one.
Cheerio! ..Off to rehearsal now..
