The Pentek ECP5-BB is a 5-micron pleated cellulose polyester sediment filter designed for whole house applications. This nominal 5-micron rating effectively captures sediment, silt, sand, rust, and scale particles from your incoming water supply, providing superior pre-filtration for your home. The pleated design offers a greater surface area than standard spun or melt-blown filters, resulting in higher dirt-holding capacity and longer service life.

The Pentek ECP5-BB measures 9-3/4" in length and 4-1/2" in diameter (Big Blue size), making it compatible with all standard Big Blue whole house filter housings. It fits Pentek Big Blue housings such as the 20BB, 150233, 150234, and 150235 series, as well as other manufacturers' housings that accept standard 10" x 4.5" Big Blue cartridges. Always verify your housing size before ordering to ensure proper fitment.

The Pentek ECP5-BB should be replaced every 3 to 6 months, depending on your water quality and household usage. Homes with higher sediment content in their well or municipal water may require more frequent changes, while homes with cleaner water sources may extend service life closer to 6 months. A noticeable drop in water pressure throughout your home is a clear indicator that it's time to replace the cartridge. Regular replacement protects downstream appliances, plumbing fixtures, and any post-filters in your system.

The Pentek ECP5-BB is manufactured from FDA-compliant materials and the media meets NSF/ANSI Standard 42 for material requirements. It supports a maximum flow rate of up to 20 gallons per minute (GPM), making it ideal for whole house applications where consistent water pressure is critical. It operates within a temperature range of 40°F to 125°F (4.4°C to 51.7°C) and a maximum pressure of 125 psi.

The ECP5-BB features a pleated cellulose polyester media that provides significantly more surface area compared to spun or melt-blown filters of the same size. This pleated construction delivers higher dirt-holding capacity, lower pressure drop, and a longer service life. Additionally, the ECP5-BB is washable and reusable in some cases, allowing you to rinse off accumulated debris to extend its usable life before final replacement, offering excellent value for whole house sediment filtration.
