If You Care Coffee Filters are made from unbleached totally chlorine-free (TCF) paper. They are totally chlorine-free, so no chlorine or chlorine derivatives are dumped into our lakes, rivers and streams. Their cone filters feature a strong “never break” patented wave seam, which assures the strength and integrity of the filters. If You Care coffee filters will not affect the taste of your coffee but they will, of course, reduce the amount of pollution in our environment. Certified by Vinçotte as compostable in backyard or home composting facilities. This is one of the world’s only home composting certifications and it is based on the European standard EN 13432.
