Including filter system and high-performance PFOS filter.
PFOS is one member of the PFAS family that can persist in water and the environment for a very long time. Because it resists breaking down, small inputs over time may lead to an ongoing presence in a local supply. Alpine residents commonly hear about PFOS from water reports, local coverage, or private testing — and the right next step is to confirm your household’s water quality and select treatment that specifically targets PFAS.
PFOS doesn’t usually change how water tastes, smells, or looks, so you can’t rely on your senses to know whether it’s present. That’s why many Alpine homeowners treat where water enters the house — a whole-house approach protects drinking, cooking, bathing, and laundry from long-term exposure risks instead of addressing only a single faucet.
For reducing PFOS throughout the house, the most effective single option is a high-capacity granular activated carbon (GAC) system formulated for PFAS removal. GAC adsorbs PFOS onto its extensive internal surface as water passes through; because PFOS can be harder to remove than simple taste-and-odor compounds, the media quality, bed depth and correct flow rate are important. A properly sized whole-house GAC unit can treat all fixtures in an Alpine home without needing separate under-sink units for each tap.
A whole-house GAC filter is placed on the main supply line so every faucet in your Alpine home receives treated water; to maintain PFOS reduction you’ll want the system sized for peak flow and serviced with timely media replacement. Mr. Pure Water can help choose a carbon configuration suited to PFOS reduction and your plumbing and usage, and periodic before-and-after testing provides added verification that the system continues to perform.
