  First Need once supplied a "coloring dye" to check their filters... I
don't know if it was only food coloring or not... I have not seen anything
like this from other filter companies, ie MSR, PUR, SweetWater, Katahdin,
Timberline, etc... 
  The companies tell you to clean the systems and when to replace the
cartridges, but I have not seen any "chemical" checks...
