Including filter system and high-performance PFPeS filter.
PFPeS is a member of the PFAS family often called a persistent or “forever” chemical because it can linger in the environment. You usually won’t detect PFPeS by sight, smell, or taste—many PFAS are present without obvious signs—so the only reliable way to know if it’s in your household supply is to test your water. In Rose, testing lets homeowners understand whether PFPeS or related compounds could be present and what steps make sense next for your family’s water.
Because PFPeS is evaluated as part of the wider PFAS group, many families choose an extra layer of treatment even when their water appears clear and tastes fine. A whole-house system treats incoming water so every faucet, shower, and appliance in a Rose home receives the same filtered water, rather than relying solely on a single point-of-use filter at the kitchen sink.
The most effective single-filter whole-house option for reducing PFPeS is a high-capacity granular activated carbon (GAC) system formulated for PFAS removal. GAC reduces contaminants by adsorbing organic compounds onto the carbon’s surface as water passes through; its effectiveness depends on the carbon grade, contact time, and correct sizing to match your home’s flow and usage. Installed at the point of entry for a Rose residence, a properly sized GAC unit treats water before it reaches the rest of the plumbing.
To keep PFPeS reduction consistent, a whole-house GAC filter must be sized for your household demand and maintained on schedule because the carbon media will eventually become exhausted. Adding a sediment pre-filter helps preserve carbon performance by preventing channeling and premature clogging. Many Rose homeowners pair a whole-house GAC system with a dedicated under-sink drinking-water filter for extra protection at the kitchen tap, and Mr. Pure Water can help select and size the right whole-house carbon solution to fit your plumbing and daily use.
