Including filter system and high-performance Haloacetonitriles filter.
Haloacetonitriles are disinfection byproducts formed when chlorine or chloramine reacts with natural organic material in source water. They often occur at low concentrations, but some homeowners in Century choose to lower them as part of overall water-quality improvements. Because these compounds form during disinfection, they can be present even when water appears clear and tastes normal. The only way to know if haloacetonitriles are in your household water and at what level is through a laboratory water test.
Haloacetonitriles belong to the same family of disinfection byproducts that includes trihalomethanes (THMs) and haloacetic acids (HAAs), and concentrations can shift with changes in source water and treatment practices. That variability means one test result might differ from another over time. Many Century residents begin considering treatment after noticing stronger chlorine odors, altered taste, or skin irritation from chlorinated water—symptoms that don’t specifically identify haloacetonitriles but do prompt action. A whole-house system is often preferred because it conditions the water used for drinking, cooking, bathing, and laundry throughout the home.
To reduce haloacetonitriles across your Century property, a whole-house activated carbon filter is generally the best single-filter choice. Catalytic carbon—a specialized activated carbon—is commonly recommended because it addresses a broader range of chlorine-related compounds while enhancing taste and odor. By lowering the disinfectant residual that contributes to byproduct formation, carbon filtration can also limit what forms later in plumbing. The outcome is treated water delivered to every faucet and shower without altering daily water use.
Effective removal depends on sufficient carbon contact time, so correct sizing and flow rate are important for whole-house systems serving Century homes. A properly designed unit uses a high-capacity carbon tank sized for typical household demand rather than small cartridges that exhaust quickly. Regular media replacement keeps performance steady and prevents breakthrough as the carbon becomes saturated. Mr. Pure Water can help recommend a whole-house catalytic carbon setup that fits your home and targets haloacetonitriles for cleaner, more comfortable water.
