Discolored filters:
Filter discoloration is natural and will vary depending on water. Replace filter about every two months (depending on use and local water quality), or when performance starts to deteriorate. If you see that the filter has a heavy build-up of impurities or notice the presence of persistent odors associated with poor water quality, change the filter more frequently.
