If You Care Coffee Filters are made from unbleached totally chlorine-free (TCF) paper. Like all If You Care paper products, these Coffee Filters are totally chlorine-free, so no chlorine or chlorine derivatives are dumped into our lakes, rivers and streams. Our cone filters feature a strong “never break” patented wave seam, which assures the strength and integrity of the filters. They also have a tab for ease in opening each filter. If You Care coffee filters will not negatively affect the taste of your coffee, as a bleached product may do. And of course, they help reduce the amount of pollution in our environment.
