Description
Whole-home filtration
Three-stage sediment and carbon filtration with a complete spare-filter supply
This point-of-entry system connects to the main cold-water line and filters water before it reaches faucets, showers and connected appliances. One filter set is installed, and two additional sets are included for future maintenance.

What it does
Three filtration stages work together throughout the home
Water flows through a particulate prefilter followed by two complementary carbon stages for broad, practical whole-house filtration.
Installed where the main water supply enters the home, the system helps capture visible particles and improve chlorine-related taste and odor before water is distributed through the plumbing.
Stage 02
Granular Activated Carbon
A high-flow GAC stage helps reduce chlorine, many common VOCs, unpleasant tastes and odors.
Stage 03
CTO Carbon Block
A denser final carbon stage provides additional contact time for chlorine, taste and odor polishing.
Key benefits
Practical filtration, service access and replacement value
Whole-home coverageOne point-of-entry system filters water for connected faucets, showers and appliances.
Dual carbon treatmentGAC supports household flow while the CTO block provides a final polishing stage.
Semi-clear housingsVisible sumps make it easier to monitor sediment buildup and cartridge condition.
Extra filter supplyTwo complete spare sets—six cartridges—are included in addition to the installed set.
Common plumbing size3/4″ NPT inlet and outlet connections suit many residential main-water installations.
Service valves includedTwo shutoff valves help isolate the system during installation and future filter changes.
Housing wrench includedThe supplied wrench assists with opening the sumps during routine cartridge replacement.
Assembled in the USADesigned and assembled in the United States from domestic and imported components.
Reduction guide
What the included filters help reduce—and what requires other treatment

Before purchase and installation
Good to know
!
This is not a water softenerSediment and carbon filters do not remove dissolved hardness minerals. Use a softener when hardness reduction is required.
!
Check whether your city uses chloramineStandard GAC and CTO filters are intended primarily for chlorine. Chloramine treatment generally requires catalytic carbon.
!
Use on the main cold-water lineInstall after the main shutoff or pressure regulator and before the plumbing divides whenever whole-home coverage is desired.
!
Professional installation is recommendedUse a licensed plumber and follow local plumbing and building codes. Confirm flow direction before connecting the system.
!
Protect housings from sunlight and freezingDirect sunlight may encourage algae growth, and freezing temperatures can crack housings and cause leaks.
!
Leave service clearance below the housingsAllow enough space to unscrew and lower each sump during cartridge changes.
!
Flush new carbon filtersInitial dark water or cloudiness may be caused by harmless carbon fines and trapped air. Flush through a cold-water faucet before normal use.
!
Inspect for leaks after servicePressurize the system slowly and check all housings, fittings and valves immediately and again during the following 12 hours.
Filter life and reduction performance vary with water chemistry, pressure, flow rate and household usage. This system is not intended to make microbiologically unsafe or unknown-quality water safe to drink. Test private-well or unknown water and select treatment based on the test results.

Fut well, no water smell, value for money.
Jeremy Wolf –
Very easy DIY set up. I wish I would have installed this years ago. I ran my water for about 10 minuets and noticed a difference right away. Before I installed this product after taking a bath in my porcelain tub I always had to clean the rust dirt ring off with cleaner with this system I do not have to clean the tub after every use. Also I treated my well 2 weeks prior with well safe for Sulphur smell after using this filter system the Sulphur smell and chlorine smell is gone. I highly recommend this product!
