HDX QP6-06 is a water filter pitcher that uses a universal filter cartridge to reduce the presence of chlorine, taste, and odor from tap water. The filter has been tested and certified by the Water Quality Association (WQA) against NSF/ANSI Standard 42 for the reduction of chlorine. It has a capacity of 6 cups and is easy to use. Simply fill the pitcher with tap water, and the filter will automatically remove impurities as the water passes through. The filter should be replaced every 40 gallons or approximately 2 months. The pitcher is made of durable plastic and is BPA-free.
