  • Performance capacity depends on system design, flow rate and certain other application conditions.
  • When greater chlorine taste & odor reduction is needed, use the standard EP series blocks.
  • EPM-Series cartridges will contain a very small amount of carbon fines (very fine black powder). After installation, follow the instructions for flushing the cartridge to remove the fines before using the water. You should run (flush) the tap at least 20 seconds prior to using water for drinking or cooking purposes. This is particularly important if the tap has not been used daily.

Warning: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
