Including filter system and high-performance Chlordecone filter.
Chlordecone is a long-lasting pesticide that can persist in the environment long after use. When it reaches source water, it may occur at very low concentrations that aren’t detectable by taste or smell, so many Marathon homeowners wouldn’t notice without testing. Because it gives no obvious warning signs, families often choose to address it where water first enters the house to protect every tap and appliance consistently.
Even if your water looks and smells normal, trace contaminants such as chlordecone can still be present, and treating only a single faucet may leave other uses unprotected. For homes in Marathon—whether on municipal supply or a private well or cistern—a whole-house system treats water before it reaches showers, sinks, laundry and appliances, giving consistent coverage without changing daily routines.
An activated carbon whole-house filter is generally the most effective single-filter option for reducing chlordecone. Carbon media adsorbs many organic and pesticide-type compounds by trapping them on its surface and within its pores, which makes it suitable for small concentrations that sediment filters won’t catch. Installed at your main supply line, it treats the water before it flows to any fixture in the home.
To work well, a whole-house carbon system must be sized so water spends enough time in the media and there’s adequate carbon volume for your household’s flow. Proper sizing and regular maintenance keep the carbon performing as it captures contaminants while you continue using water normally. In Marathon’s tropical maritime climate, coastal corrosion concerns and local supply types can affect system placement and materials; Mr. Pure Water can help confirm the right fit and sizing based on your flow needs and any available test results.
