Including filter system and high-performance Haloacetonitriles filter.
Haloacetonitriles are disinfection byproducts that can form when municipal disinfectants like chlorine or chloramine react with natural organic matter in source water. They’re usually found at low concentrations, but many Scanlon homeowners choose to reduce them as part of improving overall water quality. Because these compounds are produced during regular disinfection, they may be present even when water looks clear and tastes normal. The only way to know for sure if haloacetonitriles are in your home water and at what level is to run a proper laboratory test.
Haloacetonitriles belong to the broader class of disinfection byproducts that includes trihalomethanes (THMs) and haloacetic acids (HAAs). Their concentrations can shift over time with changes in source water and treatment practices, so one test may not match another taken later. Many people in Scanlon begin considering treatment after they notice stronger chlorine odor, altered taste, or skin irritation from chlorinated water—even though those signs don’t specifically identify haloacetonitriles. A whole-house system is a common choice because it treats water used for drinking, cooking, bathing and laundry throughout the home.
To reduce haloacetonitriles across the whole house, an activated carbon whole-house filter is generally the single most effective option. Catalytic carbon—a specialized activated carbon—is often recommended because it handles a broader range of chlorine-related compounds while also improving taste and odor. By reducing the disinfectant residual that contributes to disinfection byproducts, carbon filtration can help limit further formation in your plumbing. The outcome is treated water at every faucet and shower in your Scanlon home without changing how you use water day to day.
Effective removal depends on sufficient carbon contact time, so proper system sizing and flow rate are important for whole-house installations. A correctly designed setup uses a high-capacity carbon tank sized for typical household demand rather than small cartridges that can exhaust quickly. Regular media replacement maintains consistent removal and prevents breakthrough as the carbon reaches capacity. Mr. Pure Water can help Scanlon homeowners choose a whole-house carbon configuration that fits their home and targets haloacetonitriles for a cleaner, more comfortable water experience.
