The Pentek NCP-BB is a 5-micron nominal pleated cellulose polyester filter cartridge. This micron rating makes it highly effective at reducing sediment, dirt, silt, sand, rust particles, and scale from your whole house water supply. The pleated design provides a larger surface area than standard spun or melt-blown cartridges, allowing for higher dirt-holding capacity and longer service life in Big Blue style housings.

The Pentek NCP-BB cartridge typically lasts 3 to 6 months depending on your water quality, usage, and sediment load. For households with heavier sediment or well water, replacement may be needed closer to the 3-month mark, while homes on cleaner municipal water may extend service toward 6 months. One key advantage of the NCP-BB is that it can be removed, rinsed, and reused multiple times before final replacement, which helps extend its overall value.

The Pentek NCP-BB measures approximately 9-3/4" in length and 4-1/2" in outer diameter, making it a standard Big Blue size that fits most 10-inch Big Blue whole house housings, including Pentek 150233, 150235, and compatible 4.5" x 10" systems. It is rated for a maximum flow rate of 8 GPM (gallons per minute) and operates within a temperature range of 40°F to 125°F with a maximum pressure of 100 psi.

Yes, the Pentek NCP-BB is a reusable pleated cartridge made from cellulose polyester media with a polypropylene core and end caps. Because of its pleated construction, you can remove the cartridge, rinse off accumulated sediment with clean water, and reinstall it to extend its usable life. This makes the NCP-BB more economical than single-use spun polypropylene cartridges for applications with high sediment loads.

The Pentek NCP-BB is specifically engineered for mechanical sediment filtration. It reduces dirt, sand, silt, rust flakes, scale particles, and other suspended solids 5 microns and larger throughout your entire home's water supply. It is ideal as a pre-filter to protect downstream equipment like water softeners, carbon filters, UV systems, and household appliances. Note that this cartridge does not reduce chlorine, taste, odor, or chemical contaminants — pair it with a carbon-based cartridge for those needs.
