The Active Patch™ filter is a single-segment carbon filter. It retains a similar taste to traditional mono-acetate filters while providing the benefits of an activated carbon.
Consists of high-quality crimped cellulose acetate fibres that are bonded firmly. This is enclosed in an outer plugwrap, which can be standard or porous depending on the ventilation requirements. This plugwrap is applied with a patch of granular-activated carbon.
The activated carbon patch can be in a single patch formation or laid out in a split patch configuration surrounding the ventilation zone of the finished product where increased loadings are required.
