Quality With Integrity FSC® CertifiedUnbleached Totally Chlorine-Free (TCF)Ideal for Kettles and Tall Mugs Why Use If You Care FSC® Certified Unbleached TCF Tea Filters? FSC, the Forest Stewardship Council®, is an international non-profit organization that promotes responsible forest management through a rigorous certification system which certifies well managed forests and the products that come from them (wood, paper, etc.). Yearly more than 30 million acres of natural forests are destroyed by illegal logging and land clearance for development or agriculture. When you buy If You Care FSC Certified Tea Filters, you know that the paper came from forests that comply with the most rigorous environmental and social standards. That is why FSC is endorsed by many highly regarded non-profit environmental organizations.  If You Care Tea Filters are made from unbleached, totally chlorine-free (TCF) paper. Since no chlorine or chlorine derivatives were used to produce these filters, no chlorine or chlorine derivatives get dumped into our lakes, rivers and streams.  Product Lifecycle Source Materials Tea Filters Unbleached paper from FSC-certified forestsFilters are totally chlorine-free (TCF) Cardboard Box Board from FSC-certified recycled paperProcesses chlorine-free (PCF)Biodegradable non-toxic inks and glues Environmental Benefits Certified paper from well-managed forestsFilters are totally chlorine-free (TCF)Board is recycled, processes chlorine-free (PCF)Minimum waste Usage Perfect for brewing loose tea Disposal Cardboard is biodegradable but should be recycled
