How often should I change my refrigerator filter?

All refrigerator manufacturers recommend that the filter in their refrigerators be changed at least every six months. More often if the water has an odor or an unpleasant taste. Did you know that the human body is over 70% water? Federal, state and local authorities strive to insure that we get the best water possible but changing your filter at least every six months will help protect your family from water-borne parasites like Cryptosporidium parvum, Entamoeba histolytica, and Giardia lamblia.
