Karma filters are made 100% biodegradable and handmade and are very pleasant to drive. Environmentally friendly, they contain seeds of red amaranth, common basil, sacred basil and spinach.
Karma is a brand of ecological filters manufactured according to a patented process where fruit and vegetable pulp is used to create paper. Seeds are added during the process and are protected against nicotine and heat, while being protected by specially designed paper, which also absorbs tar naturally.
Very good alternative to standard cardboard filters. Now it's basil, spinach and red amaranth that grow when you throw away your cigarette butts!
