King Size filter. Silica gel with its highly porous structure reduces tar and nicotine from tobacco smoke to a high extent. By changing color from clear white to dark brown the effect is clearly shown, and it indicates when the filter has to be changed. Only the original Denicotea filter has the red cap!
have been using dinicotea since the 1960s. could not smoke without them.
they cut down a great deal of the tar & nicotine & (do not know if its the filters or genetics) can run up 6 flights of stairs & recover in about a minute.
Also it is really easy to order on line, the people I speak with are friendly & efficient and friendly, always.

I have been using denicotea filters for years on recommendation from my mother-in-law. At that time they could be purchased at the local tobacco shop or pharmacy. I now have to order them online, but I don't mind. That's how much it means to me. Although I should quit smoking altogether, until then this will do.
