Pentek NCP-20BB Big Blue Carbon Water Filter — 20-Inch, 10 Micron, Whole-House Filtration

Overview

The Pentair Pentek NCP-20BB is a 20-inch carbon-impregnated pleated cartridge designed for whole-house filtration. It blends a pleated polyester structure with carbon filtration to target sediment and chlorine-related compounds, delivering a balanced approach to water quality. This non-cellulose design aims to combine durability with effective contaminant reduction, giving you the flexibility to support a range of municipal and non-chlorinated water supplies.

With a 10 micron rating, the cartridge is engineered to handle a meaningful amount of dirt while preserving a steady flow. The pleated media increases surface area, which can contribute to a high dirt loading capacity and a relatively low pressure drop compared with some stacked-filter configurations. In practical terms, this means fewer cartridge changes and a consistent performance profile across many homes.

Key Benefits

• Provides superior sediment filtration and chlorine taste and odor reduction
• Fits all 20" Big Blue housing and can replace any 20" x 4.5" carbon filter
• Suitable for municipal and non-chlorinated water applications unlike cellulose cartridges
• High dirt loading capacity with minimal pressure drop due to the pleated design
• Combination of pleated polyester media and carbon filtration for extended service life

What to Expect in Daily Use

In typical home setups, you may notice improved water clarity and a more neutral taste, especially if your supply contains chlorine or taste-and-odor compounds. The filter is designed to support whole-house filtration without frequent cartridge swaps, making maintenance a part of your routine rather than a major project. The 10 micron filtration level targets fine particulates while the carbon layer helps address odors and tastes associated with certain water sources.

Compatibility and Applications

• Compatible with ALL 20" Big Blue housings
• Can replace any 20" x 4.5" carbon filter
• Appropriate for municipal water and non-chlorinated water sources

Note: Results depend on your specific water quality and system configuration. Regular system checks and timely cartridge changes help sustain filtration performance and water quality over time.
