Softener + Catalytic Carbon Tank + Pre-Filter + FREE RO

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.
Softener with Catalytic Carbon Tank and Pre-Filter
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.
$3,997
  • No salt to refill, ever
  • Filter needs to be changed every 1-2 years
  • Licensed Texas plumber installation
  • 1-year Labor, 5-year Valve, 10-year Tank Warranty
  • waterfilterdepot.co/warranty
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.
