Are your paper filters bleached?
Our paper filters are made using an ECF (Elemental Chlorine-Free) bleach pulp. ECF bleaching methods, which do not involve the use of chlorine gas, are environmentally-conscious means of bleaching that enable significant reductions in absorbable organic chlorinated compounds found in factory water discharge. Non-chlorinated, unbleached products are also available in our WTF series.
