Product review (1 stars): Metallic taste / bad filters
I replaced the GE filter in my refrigerator water system with one of these cheaper filters.  I figured one carbon block was the same as any other.  The water tasted fine b/4 the switch, it was just in use for a year so i figured it should br replaced.  Within a day the water had a disagreable metallic taste.  Since i had three of them, i switched it out for another new one.  Initially after purging the system the water was good.  The next day it was back to the disagreable metallic taste.  I went out and purchased a GE filter, installed and purged.  The water has been good for two months now.  No more cheap filters for me!  The third cheap filter went to the trash.  Wasted money to cheap China product.
