Frequently Asked Questions

What is the micron rating of the Pentek NCP-20BB whole house filter?

The Pentek NCP-20BB is a nominal 20-micron pleated cellulose polyester filter cartridge. This rating makes it highly effective at reducing sediment, sand, silt, rust particles, and scale from your whole-house water supply while still maintaining excellent flow rates. The 20-micron rating is ideal for moderate sediment reduction without overly restricting water pressure across your home's plumbing.

How long does the Pentek NCP-20BB filter last, and when should I replace it?

The Pentek NCP-20BB typically lasts 3 to 6 months depending on your incoming water quality and household usage. Because it's a pleated design with a large surface area, it offers a longer service life than comparable spun or melt-blown cartridges. A noticeable drop in water pressure is the clearest sign it's time to replace the cartridge. For homes with heavy sediment loads, replacement closer to the 3-month mark is recommended.

What housings is the Pentek NCP-20BB compatible with?

The NCP-20BB is a Big Blue-sized cartridge measuring 20" in length with a 4.5" outer diameter, making it compatible with most standard 20" Big Blue whole house filter housings, including Pentek's own Big Blue series. Always confirm your housing accepts a 20" x 4.5" cartridge before ordering to ensure a proper fit and seal.

Is the Pentek NCP-20BB NSF certified, and is it safe for potable water?

Yes, the Pentek NCP-20BB is manufactured from FDA-compliant materials and the cartridge components are tested against NSF/ANSI Standard 42 for material safety and structural integrity, making it safe for use in potable (drinking) water applications. It's specifically designed for whole-house sediment reduction rather than chemical or taste/odor removal.

Can the Pentek NCP-20BB be cleaned and reused?

Yes — one of the key advantages of the NCP-20BB's pleated cellulose polyester construction is that it can be rinsed and reused several times before final replacement, making it a more economical choice over time. Simply remove the cartridge, rinse it with clean water to dislodge trapped sediment, and reinstall. However, once flow rate remains reduced even after cleaning, it's time to install a fresh NCP-20BB cartridge.
