Premium 3-stage replacement set

Complete sediment, GAC and coconut-shell carbon-block set for standard slim whole-house systems

This three-cartridge set replaces one complete filtration cycle in compatible 3-stage whole-house systems. The filters install in sequence to capture suspended particles, support chlorine reduction and provide final taste-and-odor polishing.

What it does

Restores the three-stage filtration sequence in compatible whole-house systems

Install the cartridges in the correct order: sediment first, granular activated carbon second and premium coconut-shell carbon block third.

Stage 01

5-Micron Sediment Filter

Helps capture dirt, sand, silt, visible rust particles and suspended scale debris while helping protect the two carbon filters that follow.

Stage 02

Granular Activated Carbon

Helps reduce chlorine, unpleasant taste and odor, and many common VOCs while allowing practical flow through standard slim housings.

Stage 03

Premium Coconut Carbon Block

Provides final carbon polishing to help further reduce chlorine-related taste and odor and improve overall water quality.

What is included

One complete three-cartridge replacement set

✓One 5-micron sediment filter cartridge
✓One granular activated carbon filter cartridge
✓One premium coconut-shell activated carbon block cartridge
✓Three filters total—one complete change for a compatible 3-stage system

Reduction guide

What the complete filter set helps reduce

The three media types address suspended particles and chlorine-related water-quality concerns. Actual performance depends on source water and operating conditions.

Helps reduce

Sediment
Dirt and silt
Sand
Visible rust particles
Suspended scale debris
Chlorine
Unpleasant taste
Unpleasant odor
Many common VOCs
Particle-related cloudiness

Actual reduction and cartridge life depend on water chemistry, sediment load, pressure, flow rate, household use and filter condition.

Not designed to remove without specialty treatment

Hardness minerals
Dissolved scale
Dissolved iron
Fluoride
Chloramine
Bacteria or unsafe water
Dissolved salts / TDS

Chloramine generally requires catalytic carbon; hardness usually requires a softener; microbiological concerns require suitable disinfection; dissolved contaminants may require specialty media or reverse osmosis.

Other Standard Slim Systems

May fit other three-stage systems that use standard 10″ × 2.5″ drop-in cartridges. Confirm housing size before purchase.

Before purchase

Good to know

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

Install in the correct sequence
Sediment must be first, followed by GAC and then the premium carbon block.

This set is not a water softener
The included media does not remove dissolved hardness minerals or prevent all mineral scale.

Check for chloramine
Standard GAC and carbon-block media are intended primarily for chlorine. Chloramine generally requires catalytic carbon.

Replacement timing varies
Heavy sediment, high household use, reduced pressure, or returning taste and odor may require earlier replacement.

Flush new carbon filters
Initial dark water may be caused by harmless carbon fines. Flush until the water runs clear before normal use.

This replacement set is intended for compatible standard slim housings and does not include filter housings, a mounting bracket, wrench, valves or plumbing fittings. It is not intended to make microbiologically unsafe or unknown-quality water safe to drink.
