The very first products hold a special place in our hearts. 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 lakes, rivers, and streams. The 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 environment.
