Including filter system and high-performance PFBA filter.
PFBA is one of the PFAS compounds homeowners may find in household water. In Marathon, whether you get water from the municipal supply or a private well or cistern, people often discover PFBA through routine testing, a utility notice, or questions about water quality. Because PFBA is persistent in the environment, many Keys families prefer a treatment strategy that reduces it at every tap—helping you feel more secure about water used for drinking, cooking, and bathing in homes from Key Colony Beach to Grassy Key.
PFBA can be present even when water looks and tastes normal, and it sometimes appears alongside other PFAS. That’s why homeowners in Marathon often select systems that address a broader suite of contaminants rather than relying on basic taste-and-odor fixes. The first practical step is an up-to-date water analysis so you know what’s in your supply; from there we can size a whole-house solution to suit your moderate-hardness water and the way your household uses water.
To reduce PFBA where water enters your home, a whole-house granular activated carbon (GAC) filter is typically the most effective single-filter option. GAC removes many organic contaminants, including numerous PFAS, by adsorbing them as water passes through the carbon media. A correctly sized GAC tank delivers the contact time needed for improved reduction and treats every faucet, shower, and appliance—important for coastal Marathon properties exposed to salt air and storm conditions that can accelerate plumbing corrosion.
Because PFBA can be harder to address than some larger PFAS, removal performance depends on carbon quality, bed depth, and flow rate—not just installing a cartridge. Mr. Pure Water configures whole-house GAC systems for Marathon homes to match household demand and help preserve effective contact time in the media. Regular media replacement keeps the carbon from becoming exhausted; if your testing shows multiple PFAS, we’ll recommend a configuration that prioritizes PFBA reduction while supporting broader PFAS treatment goals.
