Including filter system and high-performance PFTrDA filter.
PFTrDA is one of the PFAS family of chemicals that can migrate from industrial and consumer uses into local water supplies. These compounds are persistent, so they can remain in water long after the original source is gone. While PFAS is often discussed as a group, individual chemicals like PFTrDA may appear on lab panels and reports; if PFTrDA shows up in results, many Key West homeowners look for a whole-home, practical solution to lower it throughout their house.
PFTrDA won’t make your water cloudy or change its smell or flavor, so testing is the only reliable way to know if it’s present. Even when municipal supplies meet regulatory limits, some residents in Monroe County prefer extra protection for showering, cooking, and washing. A whole-house system treats every faucet and appliance in the home—whether you live in Old Town, New Town, or near the Southernmost Point—so water used for daily tasks is consistently filtered.
For PFTrDA, the most reliable single-filter whole-house option is a high-capacity activated carbon system using granular activated carbon (GAC). GAC reduces many longer-chain PFAS by adsorbing them onto the carbon media as water flows through. Because PFTrDA is a longer-chain PFAS, quality carbon media is often effective at capturing it; proper tank sizing and sufficient contact time are important so the media can perform at Key West household flow rates and the area’s moderate water hardness.
A whole-house carbon filter is fitted at the main water entry so every tap and appliance—showers near Duval Street, laundry in The Meadows, or sinks in Casa Marina—gets treated water without separate under-sink units. To maintain PFTrDA reduction, the carbon media must be replaced on a schedule tied to your usage and system capacity; adding a sediment pre-filter helps protect the carbon from clogging and channeling. Mr. Pure Water can assess Key West homes and recommend the properly sized whole-house GAC system to address PFAS like PFTrDA across your property.
