Including filter system and high-performance Endrin filter.
Endrin is a synthetic pesticide that can linger in the environment long after use. Though it’s not commonly applied today, legacy contamination from agricultural or industrial sources can sometimes show up in water supplies, and homeowners usually can’t detect it by taste, smell, or sight. In Marathon, whether you’re on municipal water or a private well or cistern, routine testing is the only reliable way to know if endrin is present and whether steps are needed to address it.
As an organic chemical, endrin behaves differently than the minerals that cause moderate hardness here in the Keys. Even at very low concentrations, many homeowners choose to reduce it as part of improving overall water safety and taste. A whole-house system treats water where it enters your Marathon home—so water for bathing, cooking, laundry and brushing teeth all benefit, rather than treating only a single faucet.
For reducing endrin, the best single-filter option is a whole-house activated carbon system sized for your household flow and usage. Activated carbon adsorbs many organic and pesticide-type contaminants as water moves through the media. Compared with small under-sink cartridges, a correctly sized whole-house carbon tank gives the necessary contact time and capacity to treat water throughout a Marathon residence, making it a practical choice for broad, daily reduction rather than spot treatment.
Performance depends on your water chemistry, flow rate and the amount of carbon media, so the system should be matched to your home and routinely maintained. When carbon becomes saturated it will lose effectiveness, so timely media replacement is key to ongoing endrin reduction. Many Marathon homeowners add a sediment prefilter to protect the carbon bed from clogging—especially useful here with coastal salt air and storm exposure that can affect plumbing—and Mr. Pure Water can recommend and install a whole-house activated carbon filter tailored to your needs.
