Including filter system and high-performance Selenium filter.
Selenium is a naturally occurring element that can dissolve out of certain rocks and soils and enter groundwater. While small amounts are part of normal nutrition, drinking water isn’t a controlled source, so elevated concentrations are a concern for homeowners. Because you won’t be able to taste, smell, or see selenium in your water, the only reliable way to know if it’s present in a Three Lakes home is to test your source. If lab results indicate higher levels, the next step is selecting treatment that specifically targets selenium.
Selenium can exist in several chemical forms, and some are more difficult to remove than others. Many whole-house systems designed for chlorine, odors, or sediment won’t effectively reduce dissolved contaminants like selenium. That’s why we start by reviewing your water chemistry—especially in Three Lakes, where hard groundwater from the Floridan aquifer is common—then choose media and technology that match the challenge. With the right plan, you can reduce selenium at every tap for drinking, cooking, bathing, and laundry.
For whole-home treatment, the single most effective filter type for selenium removal is a reverse osmosis system installed at point of entry. Reverse osmosis separates dissolved contaminants using a semipermeable membrane, so it’s better suited to removing selenium than basic carbon filters. A complete whole-house RO installation also includes prefiltration to protect the membrane from sediment and chlorine—important steps for Three Lakes homeowners dealing with hard, mineral-rich aquifer water.
Because selenium’s behavior depends on its chemical form and your water’s overall makeup, a whole-house reverse osmosis system should be sized and configured for your household flow and source conditions. Pretreatment reduces scaling and fouling that can shorten membrane life—particularly relevant in hard Floridan aquifer water—while routine maintenance keeps removal levels consistent. Mr. Pure Water can assess your Three Lakes home, design a point-of-entry RO system with the right pretreatment, and install it so you get dependable selenium reduction without compromising everyday water use.
