The Pentek ECP5-10 is a 5-micron pleated cellulose polyester sediment filter designed to reduce sand, silt, rust, scale particles, and other suspended solids from your water supply. Its pleated design provides a larger surface area than standard spun or melt-blown filters, offering higher dirt-holding capacity and longer service life while maintaining excellent flow rates for under-sink applications.

The Pentek ECP5-10 measures 9-7/8" in length and 2-5/8" in outer diameter, making it compatible with standard 10-inch slim-line filter housings. It fits Pentek, Pentair, and most other brand housings that accept 9-7/8" x 2-5/8" cartridges, including common under-sink systems and whole-house pre-filtration setups using standard 10" Big Blue slim housings.

The Pentek ECP5-10 should typically be replaced every 3 to 6 months, depending on your water quality and usage. Homes with higher sediment levels or well water may need replacement as often as every 2–3 months, while municipal water users with cleaner supplies can often go the full 6 months. Replacing on schedule prevents pressure drops and protects downstream filters and equipment.

Yes, the Pentek ECP5-10 is certified to NSF/ANSI Standard 42 for material safety and structural integrity. It is constructed from FDA-compliant pleated cellulose polyester media with a polypropylene core and plastisol end caps, ensuring it is safe for potable water applications and free from binders, adhesives, or surfactants that could affect water quality.

The Pentek ECP5-10 is a disposable cartridge and is not designed to be cleaned or reused. While the pleated cellulose polyester media can be lightly rinsed in some cases to extend short-term service, this significantly reduces filtration efficiency and structural integrity. For consistent 5-micron sediment reduction and reliable flow, replace the cartridge once the pressure drops or the recommended service interval is reached.
