Pentek - NCP-20BB - 20" x 4.5" Pleated Carbon-Impregnated Polypropylene 10 Micron Filter
20" x 4.5" Pleated Carbon-Impregnated NCP-20BB 10 Micron Filter
Dual-action sediment and carbon filtration in a single pleated cartridge engineered for whole-house, well water, and commercial applications
Carbon-impregnated pleats deliver sediment filtration and chlorine reduction without bacterial growth
Carbon-Impregnated Polyester
Non-cellulose media resists bacterial attack, making the NCP-20BB ideal for both chlorinated municipal water and non-chlorinated well systems where cellulose filters fail
High Surface Area Pleating
Pleated construction increases dirt-loading capacity and extends service life while maintaining minimal pressure drop across the filter, even at 10 GPM flow rates
Dual-Action Filtration
Captures sediment down to 10 microns while simultaneously reducing chlorine taste and odor, eliminating the need for separate sediment and carbon stages in many installations
Post-RO and Polishing
Excels as a polishing filter for reverse osmosis systems, closed loop streams, and well water applications where fine sediment and taste issues persist after primary treatment

Replacement Schedule for NCP-20BB Filters
Whole-House Municipal Water
Replace when pressure drops noticeably or at 6-month intervals for household water with moderate sediment and chlorine levels
Well Water Applications
More frequent replacement required for well water with higher sediment loads or iron staining, typically every 2-3 months depending on usage
Post-RO Polishing
Extended service life when used as a final polishing stage after reverse osmosis, typically 6-12 months or after 1000 gallons processed
Commercial Installations
Install differential pressure gauge and replace when pressure drop exceeds 10-15 psi or flow rate decreases below operational requirements
Bacteria Resistant
Non-cellulose construction prevents bacterial colonization in non-chlorinated water
Low Pressure Drop
Maintains 1 psi drop at 10 GPM for consistent flow throughout service life
Dual Reduction
Removes sediment and reduces chlorine taste and odor in one cartridge
Commercial Grade
Pentek quality engineering for demanding whole-house and commercial applications
