Including filter system and high-performance Arsenic filter.
Arsenic is a naturally occurring element that can enter drinking water when groundwater or surface water contacts certain rocks and soils. Because it usually has no noticeable taste, smell, or color at levels found in homes, the only reliable way to know if it’s present is through testing. Felkel homeowners often discover arsenic from a lab report, an alert from their water provider, or after testing a private well; if arsenic shows up on your results, it’s sensible to reduce exposure at every faucet.
Arsenic exists in multiple chemical forms in water, most commonly arsenic(III) and arsenic(V), and the form affects how well treatments work. Concentrations can change over time, so a single test might not represent long-term conditions in a Felkel well or supply. The right next step is matching the treatment to your specific water chemistry so you get predictable, reliable removal.
For whole-house arsenic control in a Felkel home, a dedicated adsorptive media filter is often the most effective single-filter choice. These systems use specialized media—typically iron oxide–based or similar—that captures arsenic as water flows through the filter at the point of entry. Installed to treat all incoming water, they reduce arsenic in showers, sinks, laundry and cooking water, and focus on dissolved contaminants rather than just sediment or taste-and-odor issues.
Because the success of arsenic removal depends on your water’s chemistry, adsorptive media systems for Felkel homes are usually sized and configured based on your test results and household flow rates. If arsenic is present mainly as the form that media captures less efficiently, a simple pre-treatment such as oxidation can convert it so the filter removes it more reliably. Regular media or cartridge replacements keep the system performing, and Mr. Pure Water can help you select and size a whole-house adsorptive media filter to match your home and water report.
