Including filter system and high-performance Selenium filter.
Selenium is a naturally occurring element that can leach into water from certain rocks and soils or enter sources through industrial and agricultural runoff. While small dietary amounts are normal, drinking water isn’t a controlled source, so elevated levels are a homeowner concern. Because you can’t reliably see or taste selenium, a water test is the only way to know if it’s present in your Cornwell supply—especially since local water conditions in Florida can vary by utility and well source. If testing shows higher results, the next step is selecting treatment that specifically targets selenium.
Selenium can appear in several chemical forms, and some are more difficult to remove than others, so understanding your water chemistry matters. Many whole-house systems focused on chlorine, odor, or sediment won’t reduce dissolved contaminants like selenium. That’s why testing your Cornwell water (including hardness and any iron or sulfur issues) guides the right choice of media and pretreatment. With a tailored plan you can cut selenium exposure for drinking, cooking, bathing and laundry at every faucet in your home.
For whole-house treatment, the most effective single filter type for selenium reduction is a reverse osmosis system configured for point-of-entry use. RO relies on a semipermeable membrane to separate dissolved contaminants like selenium—materials that basic carbon filters often miss. A properly designed whole-house RO also includes prefiltration to remove sediment and chlorine before the membrane, which helps the system run reliably and deliver treated water throughout your Cornwell home.
Because selenium’s behavior depends on its chemical form and overall water chemistry, a whole‑house reverse osmosis system should be sized and set up for your household flow and source conditions. Pretreatment reduces fouling and scaling that shorten membrane life, and regular maintenance keeps removal consistent. Mr. Pure Water can evaluate your Cornwell water test results, recommend the right whole-house RO configuration, and install it so you get dependable selenium reduction without compromising everyday water use.
