Pentek - NCP-BB - 10" x 4.5" Big Blue Pleated Carbon-Impregnated Polyproplyene Filter

The Pentek NCP-BB combines sediment filtration with carbon adsorption in a single 10" x 4.5" pleated cartridge designed for Big Blue housings. This carbon-impregnated polyester filter handles chlorine taste and odor reduction while maintaining high dirt-loading capacity and low pressure drop across 500 gallons of service life.

INSTALLATION & USE

Cartridge Replacement Procedure

  1. Shut off water supply and relieve pressure by opening a downstream faucet or using the housing pressure relief button if available
  2. Unscrew the Big Blue sump using a filter wrench, remove the old NCP-BB cartridge, and clean the housing interior and o-ring groove
  3. Inspect and lubricate the o-ring with food-grade silicone grease, insert the new Pentek NCP-BB cartridge, and hand-tighten the sump until snug
  4. Turn water supply back on slowly, check for leaks, and run water for 3-5 minutes to flush carbon fines and activate the filter media
COMPATIBILITY

Housing & Application Fit

The Pentek NCP-BB fits all standard 10-inch Big Blue filter housings with 4.5-inch inner diameter, including Pentek, Culligan, GE, and Omnifilter brands. The non-cellulose construction resists bacterial growth, making it suitable for both chlorinated municipal water and non-chlorinated well water systems. This cartridge excels as a whole-house polishing filter, post-reverse osmosis carbon stage, or standalone treatment for chlorine taste and odor in closed-loop applications where sediment and organics need simultaneous removal.

🔧 Pro Tip: Replace the housing o-ring every 2-3 cartridge changes to prevent leaks, and always flush the new NCP-BB for several minutes before use to clear loose carbon particles that can cause temporary water discoloration.
