Description
High-capacity whole-home filtration
Dual-stage Big Blue filtration with 1″ brass-threaded ports and a complete spare filter set
This point-of-entry system installs on the main cold-water line and filters water before it reaches connected faucets, showers and appliances. Two large 10″ × 4.5″ housings provide sediment prefiltration followed by CTO carbon-block treatment.

What it does
Two high-capacity stages support practical whole-house water treatment
Water passes through a sediment prefilter first, followed by a carbon-block polishing stage for chlorine-related taste and odor.
Installed where the main water supply enters the home, the system helps capture suspended particles and improve chlorine-related water quality before water is distributed through the plumbing.
Stage 02
10-Micron CTO Carbon Block
Helps reduce chlorine, unpleasant taste and odor, and many common organic compounds while providing final water polishing.
Key benefits
Big Blue capacity, durable connections and convenient maintenance
Big Blue capacity
Standard 10″ × 4.5″ housings provide more media capacity than slim 10″ × 2.5″ systems.
Brass-threaded ports
Reinforced 1″ NPT inlet and outlet connections provide durable threaded plumbing interfaces.
Pressure-release buttons
Built-in pressure relief helps depressurize the housings before routine cartridge replacement.
Two complete filter sets
One sediment and CTO set is installed, and one complete replacement set is included as a spare.
Housing wrench included
The supplied Big Blue wrench assists with opening the sumps during filter service.
Preassembled bracket
The two housings arrive mounted to a heavy-duty dual metal bracket; final plumbing installation is required.
Reduction guide
What the included filters help reduce—and what requires different treatment
The sediment and CTO carbon-block combination is intended for suspended particles and chlorine-related concerns. Other water conditions may require specialty media, softening, disinfection or reverse osmosis.

Before purchase and installation
Good to know
!
This is not a water softener
Sediment and carbon filters do not remove dissolved hardness minerals or prevent all mineral scale.

Check whether your city uses chloramine
The included standard CTO carbon block is intended primarily for chlorine. Chloramine generally requires catalytic carbon.

Confirm 1″ NPT plumbing compatibility
Adapters or reducers may be needed when the home’s main line uses a different connection size.

Professional installation is recommended
Use a licensed plumber and follow local plumbing and building codes. Confirm flow direction before connecting the system.

Protect the housings and leave service clearance
Install away from freezing and direct sunlight, with enough clearance to lower both sumps during filter changes.

Flush and inspect after installation or service
Flush the new carbon filter, pressurize the system slowly, and inspect all housings and fittings for leaks immediately and again during the next 12 hours.
