Including filter system and high-performance Arsenic filter.
Arsenic is a naturally occurring element that can enter drinking water where groundwater or surface water contacts certain soils and rocks. Because it usually has no taste, smell, or color at levels people commonly encounter, you won’t notice it without testing. Century homeowners often learn about it from a lab report, a notice from their water provider, or routine private-well testing; if your water test shows arsenic, taking steps to reduce long-term exposure at every tap is a good idea.
Arsenic appears in water in different chemical forms, and that affects which treatments will work best. In household water it’s most commonly found as arsenic(III) or arsenic(V), and some filtration methods are far more effective for one form than the other. Concentrations can also change over time, so a single test may not reveal the full picture. The right next step is matching your system to Century’s water chemistry so you get steady, predictable removal.
For whole-house arsenic reduction in Century homes, a dedicated adsorptive media filter is often the best single-filter option. These systems use specialized media—often iron-oxide based—that captures arsenic as water flows through the tank. Installed where water enters the house, they treat water used for showers, faucets, laundry, and cooking, and they target dissolved arsenic rather than only removing sediment or improving taste and odor.
Because arsenic removal depends on your water’s chemistry, adsorptive media systems are sized and configured from your specific test results and household flow requirements. If the arsenic in your sample is a form the media handles less effectively, a simple pre-treatment such as oxidation can convert it so the filter captures it more reliably. Routine media or cartridge replacements keep the system performing, and Mr. Pure Water can help Century homeowners choose and maintain a whole-house adsorptive media arsenic filter that matches their water report.
