Pentek - ChlorPlus 10 - 10" x 2.5" Chloramine Carbon Block Filter

The Pentek ChlorPlus 10 (model 255416-43) is a specialized 10" x 2.5" carbon block cartridge engineered specifically for chloramine reduction in municipal water supplies. This 1-micron filter handles what standard carbon blocks cannot: the stubborn chlorine-ammonia compounds that many water utilities now use instead of free chlorine.

INSTALLATION & USE

Installing Your ChlorPlus Cartridge

  1. Shut off water supply and relieve system pressure by opening a downstream faucet
  2. Remove filter housing sump and discard old cartridge, then clean housing interior and inspect o-ring for wear
  3. Insert Pentek ChlorPlus 10 cartridge into housing, ensuring it seats properly on the standpipe
  4. Lubricate o-ring with food-grade silicone, hand-tighten sump, and slowly restore water pressure while checking for leaks
  5. Flush filter for 3-5 minutes to purge carbon fines before use
COMPATIBILITY

Housing & Application Fit

The ChlorPlus 10 fits any standard 10-inch filter housing designed for 2.5-inch diameter cartridges, including Pentek, Culligan, GE, Omni, and most aftermarket brands. Ideal for reverse osmosis pre-filtration, whole-house point-of-entry systems, or dedicated drinking water stations where municipal water is treated with chloramines. Not suitable for well water with high iron or sulfur content, which will foul the catalytic carbon prematurely.

🔧 Pro tip: Chloramine capacity drops significantly at higher flow rates—if your household uses more than 0.5 gpm average draw, plan to replace this cartridge every 4-6 months rather than waiting for taste changes, since chloramines have minimal odor even when breakthrough occurs.
