Pentair Pentek NCP-BB Big Blue Carbon Water Filter, 10-Inch, Whole House Non-Cellulose Carbon Impregnated Pleated Filter Cartridge, 10" x 4.5", 10 Micron, Pack of 2

The Pentair Pentek NCP-BB is a dual-purpose Big Blue cartridge that combines sediment filtration with chlorine taste and odor reduction in one 10-micron filter. Built from carbon-impregnated non-cellulose polyester with a polypropylene core, it handles both municipal and non-chlorinated water sources, making it a versatile choice for whole house systems, well water applications, and post-reverse osmosis polishing.The pleated media design maximizes surface area for high dirt-loading capacity while maintaining a pressure drop of just 2 psi at 8 gpm. This construction extends service life compared to flat-sheet carbon filters by allowing more contaminant contact across the expanded pleated surface. The NCP-BB is rated for 500 gallons of chlorine reduction at 2 gpm and operates within a temperature range of 40-125 degrees F (4.4-51.7 degrees C).The NCP-BB cartridge measures 4.50" x 9.75" and fits all standard 10" Big Blue and heavy-duty filter housings. It is an excellent choice for closed-loop systems, polishing applications, and anywhere dual sediment and carbon filtration is needed in a single cartridge.
