Including filter system and high-performance Selenium filter.
Selenium is a naturally occurring element that can dissolve from certain rocks and soils or enter waterways through industrial or agricultural runoff. While trace amounts are part of normal nutrition, drinking water is not a controlled source, so higher concentrations are a possible concern for homeowners. Because selenium has no color or taste, the only way to know whether it’s in your supply is a water test — Havana residents who want answers should start there. If levels are elevated, the next step is selecting a treatment that specifically targets selenium.
Selenium can occur in several chemical forms, and some species are more difficult to remove than others. Typical whole-house systems built for chlorine, taste, or sediment won’t reliably capture dissolved contaminants like selenium. That’s why a practical plan for Havana homes begins by assessing your water chemistry and then choosing the correct media and technology. With the right match, you can reduce selenium across drinking, cooking, bathing, and laundry taps throughout the house.
For whole-house removal, the single filter type most effective against selenium is a reverse osmosis system engineered for point-of-entry use. Reverse osmosis forces water through a semipermeable membrane that separates dissolved contaminants, making it far more effective for selenium than basic carbon filters. A whole-house RO installation also includes prefiltration to protect the membrane from sediment and chlorine so the system performs consistently and supplies treated water to every Havana faucet.
Because selenium’s behavior depends on its chemical form and the broader water chemistry, a whole-house reverse osmosis system should be sized and configured for your household flow and source conditions. Proper pretreatment reduces fouling and scaling that can shorten membrane life, and regular maintenance keeps removal levels steady. Mr. Pure Water in Havana can evaluate your water and recommend a whole-house RO setup so you get reliable selenium reduction without compromising everyday usability.
