Including filter system and high-performance PFTrDA filter.
PFTrDA is one member of the PFAS family that can enter drinking water when these persistent chemicals migrate from industrial sources and consumer products into the environment. Because PFAS break down very slowly, they can remain in water long after the original release. Homeowners in Stern who see PFTrDA reported on a lab panel often look for a practical, home-wide solution to lower it, rather than relying on spot treatments at individual taps.
You won’t be able to detect PFTrDA by sight, smell, or taste; laboratory testing that lists PFAS by compound is the reliable way to know if it’s present. Even when municipal or private well tests meet required limits, many Stern residents choose to further reduce trace contaminants for added peace of mind. A whole-house system ensures treated water for showering, cooking, laundry and oral care across your Stern home, so every tap benefits from the same protection.
For PFTrDA, the single most effective whole-house filter type is a high-capacity activated carbon system using granular activated carbon (GAC). As water flows through the carbon media, PFAS like PFTrDA are adsorbed onto the surface of the granules; longer-chain PFAS such as PFTrDA are typically captured more readily by quality carbon than some shorter-chain compounds. Proper sizing — enough tank volume and contact time — is important in Stern homes to maintain performance at typical household flow rates.
A whole-house GAC filter is mounted at the main water inlet so every faucet and appliance in your Stern residence is treated without multiple point-of-use units. To keep PFTrDA reduction steady, the carbon media must be replaced on a schedule that matches your water use and the system’s rated capacity. Adding a sediment pre-filter helps protect the carbon bed from clogging and channeling, and Mr. Pure Water can advise on the right-sized whole-house activated carbon system for reducing PFAS like PFTrDA throughout your home.
