Including filter system and high-performance Haloacetonitriles filter.
Haloacetonitriles are disinfection byproducts that can form when chlorine or chloramine react with natural organic matter in water. They often occur at low concentrations, but many Lois homeowners choose to address them as part of improving overall water quality. 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 supply and at what level is to have your water tested by a lab.
Haloacetonitriles belong to the wider group of disinfection byproducts that includes trihalomethanes (THMs) and haloacetic acids (HAAs). Their concentrations can change over time depending on source water and treatment practices, so one test snapshot may differ from another. In Lois, residents often look into treatment after noticing stronger chlorine odors, shifts in taste, or irritation from heavily treated water, though those signs don’t specifically identify haloacetonitriles. For many local homes, a whole-house system is appealing because it treats water used for cooking, drinking, bathing, and laundry throughout the house.
To reduce haloacetonitriles across the whole home, the most effective single-filter approach is a whole-house activated carbon system. Catalytic carbon—a specialized activated carbon—is commonly recommended because it tackles a broader range of chlorine-related byproducts while improving taste and odor. By lowering disinfectant residuals that contribute to disinfection byproducts, carbon filtration can also reduce formation of those compounds within home plumbing. The outcome is treated water at every Lois faucet and shower without changing how you use water day to day.
Effectiveness depends on sufficient carbon contact time, so correct sizing and flow rate are important for whole-house setups. A properly designed system uses a large-capacity carbon tank to handle typical household demand, rather than small cartridges that can become exhausted quickly. Regular media replacement ensures consistent removal and prevents breakthrough as the carbon loads up. Mr. Pure Water can help Lois homeowners pick a whole-house carbon configuration sized and maintained to target haloacetonitriles and deliver a more comfortable water experience.
