Including filter system and high-performance PFHxS filter.
PFHxS is one of the PFAS chemicals often called a “forever chemical” because it can persist in the environment. In Fidelis homeowners may see PFHxS included when water quality testing or utility reports list specific PFAS compounds. You won’t be able to see, smell, or taste PFHxS in your taps, so testing or targeted treatment is the only way to know whether it’s present. If you want more control over the water that enters your house, point-of-entry (whole-house) treatment is a sensible option.
Because PFHxS has been used in various industrial and consumer applications, trace amounts can appear in water sources and are not always removed by basic filters. Common pitcher filters or simple sediment cartridges can reduce particles but aren’t designed to reliably remove dissolved PFAS like PFHxS. That’s why many Fidelis residents choose a solution that treats all household water—so you don’t end up with cleaner water at just one faucet.
The single filter type most often recommended for PFHxS is a whole-house activated carbon system, particularly one using high-capacity granular activated carbon (GAC). Activated carbon’s porous surface can adsorb many organic compounds, including some PFAS, and a properly sized GAC tank on the main line gives the water enough contact time for PFHxS to bind to the media before it reaches your taps.
At Mr. Pure Water we size whole-house carbon systems for real homes—matching flow rate, bed depth, and media volume to your household’s needs in Fidelis. PFHxS performance depends on contact time and how quickly the carbon becomes loaded, so a small cartridge won’t deliver the same results as a dedicated GAC tank. We’ll help choose and size a whole-house GAC system so you get consistent filtration throughout the house without losing pressure.
