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 waterways through industrial and agricultural runoff. In trace amounts it’s a nutrient, but drinking water isn’t a measured source, so higher concentrations are a homeowner concern. You can’t rely on appearance or taste to detect selenium, so testing is the only dependable way to know if it’s in your supply — whether you live near Old Town, Truman Annex, or elsewhere in Key West — and to decide on treatment if lab results indicate elevated levels.
Selenium can exist in several chemical forms, and those differences affect how easy it is to remove from water. Many whole-house systems that focus on chlorine, odor, or sediment won’t capture dissolved contaminants like selenium, so starting with a full water analysis is important. In Key West’s warm, humid climate and moderately hard water, understanding your source water’s chemistry helps us pick the right media so you can reduce selenium for drinking, cooking, bathing and laundry across your home.
The single most effective whole-house filter type for selenium reduction is a reverse osmosis system engineered for point-of-entry use. Reverse osmosis employs a semipermeable membrane to separate dissolved contaminants such as selenium — contaminants that basic carbon filters typically don’t remove. A complete whole-house RO installation includes prefiltration to protect the membrane from sediment and chlorine, which is essential in coastal Key West where salt air and local water conditions can accelerate wear on plumbing and fixtures.
Because selenium’s behavior depends on its chemical form and overall water chemistry, a whole-house RO should be sized and configured to your household flow and Key West source conditions. Proper pretreatment reduces fouling and scaling that shorten membrane life, and regular maintenance keeps removal consistent. Mr. Pure Water can assess your home — whether you’re near Duval Street, the Southernmost Point, or in The Meadows — and recommend a whole-house reverse osmosis setup that balances dependable selenium reduction with everyday convenience.
