Including filter system and high-performance Chlordecone filter.
Chlordecone is a long-lasting pesticide that can remain in the environment long after it was used. If it reaches source water, concentrations are often low and may go undetected without testing—there’s usually no taste or smell to warn Upper Grand Lagoon homeowners. Because it’s typically invisible to the senses, many families choose to treat water where it enters the house so every tap is protected consistently.
Even when tap water looks clear in Upper Grand Lagoon, trace contaminants such as chlordecone can still be present and concerning for households wanting extra assurance. Treating only one faucet leaves other uses—showers, laundry, appliances—unfiltered, so many local homeowners prefer whole-house systems that reduce contaminants before they circulate through the home. That approach gives consistent coverage without changing daily routines.
An activated carbon whole-house filter is generally the single-filter option most effective for reducing chlordecone. Carbon media adsorbs organic chemicals and pesticide-type compounds by trapping them on the surface and inside its pores, making it suitable for small, hard-to-detect contaminants that sediment filters won’t remove. Installed at the main water line, this system treats supply water before it reaches any faucet or fixture in your Upper Grand Lagoon home.
A correctly sized whole-house carbon system relies on sufficient media volume and contact time to maximize adsorption of chlordecone as water passes through the carbon bed. When matched to your home’s flow rate, it captures contaminants while letting household water use continue uninterrupted. Like any single-media solution, it performs best with routine maintenance and periodic replacement of the carbon; Mr. Pure Water can help Upper Grand Lagoon residents confirm proper sizing and service based on your goals and any water test information you have.
