Including filter system and high-performance PFTrDA filter.
PFTrDA is one of the PFAS family of chemicals that can migrate from industrial and consumer sources into the environment and persist in water supplies. Because PFAS break down slowly, compounds like PFTrDA may remain in water long after their original source is gone. Homeowners in Marathon, whether on municipal service or local wells and cisterns, may see PFTrDA listed on lab panels and understandably want a practical, whole-home way to reduce it.
You won’t detect PFTrDA by sight, smell, or taste—lab testing that reports PFAS by compound is the reliable method to know if it’s present. Even when water meets regulatory limits, many Marathon residents prefer an extra layer of protection for peace of mind. A whole-house system treats water used for showering, cooking, laundry and brushing teeth, ensuring consistent reduction at every tap across your Florida Keys property.
For reducing PFTrDA in a whole-house setup, a high-capacity activated carbon filter—usually granular activated carbon (GAC)—is the most effective single-filter choice. Activated carbon adsorbs PFAS as water flows through the media, and PFTrDA, being a longer-chain PFAS, is generally more readily captured by quality carbon than shorter-chain variants. Correct tank sizing and sufficient contact time matter, especially in Marathon homes with moderate water hardness and variable flow rates, to ensure the system performs well under real household use.
A whole-house carbon system is placed at the point where water enters your Marathon home so every faucet and appliance receives treated water without multiple under-sink units. To maintain PFTrDA reduction, the carbon must be refreshed on a schedule based on your water use and the system’s capacity. Adding a sediment pre-filter helps protect the carbon bed from clogging and channeling—useful in coastal properties exposed to storm-driven sediment and corrosion risks. Mr. Pure Water can assess your property and recommend a properly sized whole-house GAC system tailored for PFAS reduction across your home.
