Including filter system and high-performance Arsenic filter.
Arsenic is a naturally occurring element that can enter drinking water when groundwater or surface water interacts with certain soils and rocks. Because it usually has no taste, smell, or color at typical concentrations, you won’t notice it without testing. Franjo homeowners most often learn about arsenic from a water lab report, a notice from a utility, or testing a private well; if your results show arsenic, it’s wise to reduce exposure at every tap in the house.
Arsenic in water appears in different chemical forms, principally arsenic(III) and arsenic(V), and which form is present affects how well a given filter will perform. Concentrations can fluctuate over time, so a single test doesn’t always capture the full picture. The practical next step for Franjo homes is to match your chosen treatment to your water’s chemistry so the system delivers steady, predictable arsenic reduction.
For whole-house arsenic control, a dedicated adsorptive media filter is often the most reliable single-filter choice for homes. These systems contain specialized media—commonly iron oxide–based materials—that bind arsenic as water flows through the unit. Installed at the main water entry to a Franjo home, they treat water used for showers, laundry, cooking and drinking, and focus on dissolved contaminants rather than just sediment or taste-and-odor problems.
Because effective arsenic removal depends on your water chemistry, adsorptive media systems are sized and configured based on test results and household flow needs. If your water contains arsenic in a form the media removes less readily, a simple pre-treatment step such as oxidation may be suggested so the filter can capture it more consistently. Regular cartridge or media replacements keep the system operating properly over time—Mr. Pure Water can help Franjo homeowners pick the right whole-house adsorptive media filter to match their water report.
