●Two-stage separative-filtering technique for isolating the stink of
    nicotine.
●With the patented design, a transparent, tar-separation filter is
    used to carry out effective filtration in the front section. The
    quantity of the accumulated tar can be clearly seen from the
    outside allows you to determine the filter replacement in more
    timely manner.
●The imported activated carbon filters(Bio Carbon Filter)can sift
    the small harmful particles out. Mixed, unpleasant odor can
    be effectively removed while the original taste of the cigarette
    remains intact. 
●Each cigarette filter can be repeatedly used for about 7-10
    cigarettes, depending upon the tar content.
●Drawer-like packages for easy carry.
●Designed and made in Taiwan : the product quality is guaranteed.
