A carbon filter is a 3.5cm long cardboard tube filled with activated carbon which soaks up harmful tar from smoke. As well as this the process of the smoke passing through the filter helps cool the smoke.
It is designed to fit in certain pipes but can also be used as a large filter to replace a roach, (0.7cm diameter). It is particularly good for blunts or ‘warheads’.
Each one can be used up to 3 or 4 times and they come in a pack of 10.
