The Pentek ECP5-20BB is a 5-micron pleated cellulose sediment filter. This micron rating makes it ideal for reducing sand, silt, rust, scale particles, and other fine sediment from your whole house water supply. The pleated design provides a larger surface area compared to standard spun filters, allowing for greater dirt-holding capacity and longer service life in your Big Blue 20" housing.

The Pentek ECP5-20BB typically lasts 6 to 12 months, depending on your household water quality and usage. For homes with high sediment levels (well water or heavily silted municipal supplies), replacement every 3–6 months may be necessary. The pleated cellulose polyester media is designed for extended service life, and the filter can often be rinsed once or twice to extend usage before full replacement is required.

The Pentek ECP5-20BB measures 20" in length with an outer diameter of 4.5", making it compatible with standard 20" Big Blue (BB) whole house filter housings. It supports flow rates up to 8 GPM (gallons per minute) with a maximum operating temperature of 125°F (52°C) and a pressure range of 40–100 psi, making it suitable for point-of-entry whole house filtration.

Yes, the Pentek ECP5-20BB is manufactured from FDA-compliant materials and the media is tested and certified by NSF International against NSF/ANSI Standard 42 for material requirements. This certification ensures the filter components are safe for use in potable water applications and do not leach harmful substances into your drinking water.

The ECP5-20BB is specifically engineered for sediment reduction. It removes particulate matter 5 microns and larger, including dirt, sand, silt, rust flakes, scale, and suspended solids. Note that this is a mechanical sediment filter and does not remove chlorine, chemicals, or dissolved contaminants — for those, pair it with a carbon filter in a dual-stage whole house system for complete pre-treatment protection.
