Just as adding Vitamin C to iodine can neutralize it, so can "bleached" 
water
be harmful to some filters.  Some ceramic filters have silver imbedded in 
them
to help control bacterial growth.  Filtering chlorinated water can 
neutralize
the silver, rendering the ceramic core more subject to the growth of the 
very
substances you're trying to filter OUT of the water.
