Description

High-capacity pleated sediment filtration

Reusable 5-micron pleated cartridge for well water and heavier sediment

This standard 10″ × 2.5″ pleated polypropylene cartridge provides more surface area than a conventional spun sediment filter. It is designed as a first-stage prefilter for compatible whole-house, under-sink and reverse-osmosis systems where sediment loading is moderate to heavy.

What it does

Captures suspended particles while helping maintain flow

The accordion-folded media exposes more filtration surface than a standard spun cartridge, helping increase dirt-holding capacity and extend the interval between replacements.

Primary purpose

5-Micron Sediment Filtration

Helps capture dirt, sand, silt, visible rust particles, suspended scale debris and other visible solids from incoming cold water.

Typical placement

First Filtration Stage

Install before carbon filters, specialty media or an RO membrane to help protect downstream components from grit and sediment loading.

Key benefits

More surface area, higher dirt capacity and reusable construction

PL

Pleated media
Accordion-folded polypropylene creates more filtration surface than a standard spun cartridge.

5-micron nominal rating
Captures fine suspended particles while supporting practical flow in compatible systems.

HF

Higher dirt-holding capacity
Designed to hold more sediment before flow begins to decline.

RW

Rinse and reuse
May be rinsed and reinstalled a few times before final replacement.

WW

Well-water friendly
A practical choice for moderate-to-heavy sediment loads commonly found in well-water systems.

DI

Drop-in replacement
Fits compatible standard 10″ × 2.5″ slim housings.

Dissolved iron
Hydrogen sulfide
Fluoride
Bacteria or unsafe water
Dissolved salts / TDS

Use carbon, specialty media, softening, disinfection or reverse osmosis when those treatment goals are required.

Cleaning and replacement

  • Shut off the water supply and relieve housing pressure before opening
  • Remove the cartridge and rinse from the clean side toward the dirty side
  • Use clean water only; do not use harsh chemicals or abrasive tools
  • Reinstall only if the media remains intact and flow improves after cleaning
  • Replace when flow remains low, the pleats are damaged, or cleaning no longer restores performance
  • Pressurize slowly and inspect the housing for leaks after service

Which sediment cartridge should you choose?

Pleated versus standard spun sediment

Standard Spun Sediment Filter
Best suited for municipal water or light-to-moderate sediment when the lowest replacement cost is the priority.
SED5-PLT—This Product
Better suited for well water, heavier sediment, longer service intervals and applications where rinsing and reuse are helpful.

Before purchase

Good to know

!
Confirm cartridge size
This cartridge fits standard 10″ × 2.5″ slim housings and does not fit 10″ × 4.5″ Big Blue housings.

!
Reusable does not mean permanent
Cleaning may restore flow a few times, but filtration performance declines over repeated cycles.

!
Always install first
Sediment filtration should be placed before carbon, specialty media and RO membranes.

!
Heavy sediment shortens service life
Replace sooner if the cartridge becomes heavily loaded or household pressure declines.

!
This is not a chemical filter
It does not reduce chlorine, taste, odor, dissolved iron, hardness or TDS.

!
Inspect after each cleaning
Do not reinstall the cartridge if the pleats, end caps or seals are damaged.

This product includes one replacement cartridge only. Filter housing, wrench, mounting hardware, plumbing fittings and additional filters are not included. It is not intended to make microbiologically unsafe or unknown-quality water safe to drink.
