Including filter system and high-performance PFTrDA filter.
PFTrDA belongs to the PFAS family of long-lived chemicals that can migrate from industrial and consumer uses into groundwater and municipal sources. Because these compounds break down very slowly, they may remain in drinking water even after the original source is gone. Home testing and utility reports sometimes list individual PFAS, including PFTrDA, so Athena homeowners who see it flagged often look for practical, whole-house ways to reduce their exposure.
You won’t detect PFTrDA by smell, taste, or sight—lab analysis is the reliable method to identify it and other PFAS in your water. Even when local supplies meet regulatory requirements, many people in Athena choose additional treatment as a precaution. Installing whole-house treatment ensures that water used for showering, cooking, laundry and brushing teeth across your entire home receives consistent filtration.
For addressing PFTrDA in a whole-home system, a high-capacity activated carbon setup—commonly granular activated carbon (GAC)—is the most effective single-filter option. GAC reduces many longer-chain PFAS by adsorbing them onto the carbon as water flows through. Because PFTrDA is considered a longer-chain PFAS, it is often captured more readily by quality carbon media; correct tank sizing and adequate contact time are important to ensure strong performance at typical household flow rates.
A whole-house carbon filter is fitted at the main water entry so every faucet and appliance in an Athena home is treated without multiple point-of-use units. Maintaining PFTrDA reduction requires periodic replacement of the carbon media based on your household’s water use and the system’s rated capacity. Adding a sediment pre-filter helps protect the carbon bed from clogging and channeling, keeping the system efficient. Mr. Pure Water can assess your Athena property and recommend a properly sized whole-house activated carbon system to target PFAS like PFTrDA throughout the home.
