Three stages of whole-house filtration — premium Quick-Connect sediment, high-flow GAC, and final CTO carbon block — in clear/translucent housings, with valves and unions in the box and a full year of replacement filters.

What it does

This 3-stage system installs on your main water line and treats every tap in the home from a single point. Water passes through three cartridges in sequence:

Stage 1 — Premium Quick-Connect Sediment (5 µm). A quick-connect sediment cartridge captures dirt, silt, sand, rust, and scale particles, protecting your plumbing and the two carbon stages that follow. The quick-connect body means faster, tool-lite cartridge changes.

Stage 2 — GAC Carbon (Pre-Carbon Polishing). A granular activated carbon cartridge reduces chlorine, many common VOCs, and the tastes and odors they cause. Because GAC has a loose media bed, water flows through at high volume — a great match for whole-house demand.

Stage 3 — CTO Carbon Block (Final Polish). A denser carbon block gives finer, longer-contact filtration — polishing the water and reducing any chlorine, VOCs, or off-tastes that made it past Stage 2. The result: noticeably fresher water to drink, cook, and shower with.

The system uses standard clear/translucent 10″ whole-house housings and 3/4″ NPT ports that match common main-line plumbing, and runs at typical household pressure (20–80 PSI). The clear sumps let you see the cartridge condition at a glance. In the box: one cartridge set preinstalled, two extra sets (6 cartridges total), two 3/4″ union nipples, and two 3/4″ on/off ball valves — everything the plumber needs to isolate the system for future service.

Helps reduce

With the included Quick-Connect sediment + GAC + CTO carbon block set:

On chloraminated city water, swap the Stage 2 block for a catalytic carbon cartridge. For hardness, iron, or fluoride, add the matching specialty stage — ask us and we’ll help you build the right stack.

Good to know before you buy

• This is a filtration system, not a water softener — it does not remove hardness minerals or scale.
• Standard GAC and CTO carbon reduce chlorine but not chloramine. If your city uses chloramine, swap in a catalytic carbon cartridge for one of the carbon stages.
• The Quick-Connect sediment cartridge is not interchangeable with a standard threaded 10″×2.5″ sediment cartridge — when reordering, match the QC-style set.
• Best installed on the main cold-water line after the meter/pressure regulator. The included union nipples and shutoff valves let you isolate the system for future filter changes without shutting off the house.
• Filter life depends on your water quality and household usage — heavier sediment or use means more frequent changes.
• Install the clear housings out of direct sunlight to prevent algae growth in the sumps and to extend housing life.
