  • Maximum life — dirt-holding ability of a 10-micron carbon block with the particulate efficiency of a 0.5-micron cartridge


  • Whole house cyst reduction with carbon treatment
  • Cyst reduction where low flow, high pressure drop or premature plugging has been problematic
  • Areas where low water pressure has made cyst reduction difficult due to high pressure drops (low flow)
  • High flow applications (>25 gpm possible)

  • Initial ΔP (psi) @ Flow Rate (gpm)*: 4 psi @ 4 gpm (0.3 bar @ 15.2 Lpm)
  • Chlorine Taste & Odor Reduction @ Flow Rate (gpm)*: >50,000 gallons @ 4 gpm (>189,000 L @ 15.2 Lpm)

*Based on manufacturer’s internal testing.


  • Performance capacity depends on system design, flow rate and certain other application conditions. Certain states require system registration or certification for health-related reduction claims.
  • A drinking water cartridge may contain carbon fines (very fine black powder). After installation and before using the water, follow the instructions for flushing the cartridge to remove fines.
  • It is recommended that you run the tap for 20 seconds prior to using the water for drinking or cooking purposes.

Warning: For drinking water applications, do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
