Including filter system and high-performance Trichloroacetic acid filter.
Trichloroacetic acid is a chlorinated organic compound that can form when natural organic material in source water reacts with chlorine-based disinfectants used in treatment. It belongs to a larger group commonly called disinfection byproducts, and their amounts can shift as source water and treatment practices change. Because trichloroacetic acid is dissolved, you usually won’t see it or detect it by taste or smell; many Garnier homeowners first hear about it from a water-quality report or independent testing.
Even where water meets regulatory standards, some families prefer to reduce trace contaminants as an extra precaution. Trichloroacetic acid can be present throughout the home — in showers, laundry machines, dishwashers and drinking water — so treating only the kitchen tap won’t address every exposure. For homeowners in Garnier, a whole-house approach delivers more consistent protection at every faucet and appliance while keeping daily use simple.
To lower trichloroacetic acid throughout your home, a whole-house activated carbon filter is generally the most effective single-filter choice. Systems using high-quality catalytic carbon or carbon media with extended contact time adsorb many dissolved organics and chlorinated byproducts as water flows through the tank. Installed where water enters the house, this treatment helps limit what reaches Garnier faucets, showers and appliances without needing multiple point-of-use units.
Proper sizing matters because contact time and flow rate determine how well carbon adsorption performs. In a whole-house system the tank size and media volume are chosen to match your household’s water use so performance stays steady during peak demand. Carbon media is replaced on a predictable schedule based on capacity and local water conditions rather than frequent cartridge changes. If you’d like extra assurance in Garnier, pre- and post-installation testing can verify how much trichloroacetic acid the system is removing.
