Including filter system and high-performance Phthalates filter.
Phthalates are a group of chemicals commonly used as plasticizers to make plastics more flexible. They can leach into water when plastic materials break down or when trace organics move through wastewater streams and re-enter waterways. Because phthalates appear in many everyday products, they tend to show up as low-level, intermittent contaminants rather than a steady source. In Marathon, homeowners often hear about them on water quality reports or local advisories and look for ways to reduce overall chemical exposure around the house.
Phthalates are invisible in the tap — they usually don’t change taste or smell — yet many families prefer treating their whole home to limit exposure to plastics-related chemicals. For a broad reduction of dissolved organics, a system that targets chemical contaminants is more effective than one focused solely on sediment or chlorine taste. A whole-house solution means everyone in your Marathon household benefits — from showering after a day on the water to washing clothes and preparing meals.
The most effective single-option whole-home choice for reducing phthalates and other plasticizers is a granular activated carbon (GAC) filter. GAC works by adsorbing dissolved organic compounds as water flows through the media, which makes it better suited to chemical reduction than plain sediment filters. Properly sized GAC tanks give the contact time needed to capture trace organics reliably, making them a solid standalone option for many Marathon properties.
Performance varies across the phthalate family, so system design matters: adequate carbon volume, controlled flow rates, and regular media replacement keep results consistent. A whole-house GAC unit is installed at the main water entry so every faucet in your Marathon home benefits, and pairing it with a sediment prefilter helps protect the carbon from clogging—especially helpful in coastal, humid environments where corrosion and particulates from older plumbing can be a concern. Mr. Pure Water can assess your home’s flow needs and recommend the right-sized carbon system for steady phthalate reduction day to day.
