Why catalytic carbon: Houston treats its water with chloramine, not plain chlorine. Catalytic carbon breaks chloramine down; standard activated carbon does not. The tank backwashes itself, so it replaces cartridges entirely.

Salt Free RO System Included FREE

Salt-Free Conditioner + Catalytic Carbon + Pre-Filter + FREE RO

Sediment Pre-Filter · Catalytic Carbon Tank · TAC Salt-Free Conditioner · 5-Stage RO

The no-salt alternative. TAC technology prevents scale without removing minerals or adding sodium. No salt bags, no brine discharge, no cartridges.

Why catalytic carbon is mandatory here: TAC crystal media is degraded by chlorine and chloramine. Catalytic carbon breaks chloramine down; standard activated carbon does not. It ships with every salt-free build.

Does not soften water. There is no ion exchange and no salt, so a hardness test still reads hard. This is the right system when the complaint is sediment, taste, odor, chlorine or metals, not scale.

Alkaline RO Upgrade

+$100

Upgrades the included RO to 6-stage alkaline filtration. Raises drinking water pH to 7.5-8.5 and re-mineralizes with calcium, magnesium & potassium. Available on any package.

UV Sterilizer (inline)

+$989

Inline UV unit installed on the main water line. Eliminates bacteria, viruses & pathogens without chemicals. Annual bulb replacement required. Recommended for well water & homes with young children.
