These filters are made from natural unbleached cellulose hence their brown colour. The core fibres come from FSC certified sustainably managed forests. These filter tips are biodegradable (test OECD 301B) and thus more ecological to use. However this does not mean you no longer need to throw your cigarette butt in the bin.
Environmentally friendly and biodegradable.
