Not All Filters Remove PFAS. Here’s What the Science Says.

Many filters are marketed for PFAS removal — but independent tests reveal wide variation. Some remove less than 30%. Know what you’re buying.

PFAS Filter FAQ

• Does my city water have PFAS? +
  The only way to know is to check your annual Consumer Confidence Report (water quality report), which your utility is required to publish. The EPA’s website lets you look up reports by zip code. Even if PFAS aren’t listed, note that many utilities are still in early testing phases — absence of reporting isn’t the same as absence of contamination.
• Is my private well at risk? +
  Potentially yes, and there is no federal requirement for well owners to test or be notified. Wells near military installations, industrial facilities, airports, or farms using PFAS-contaminated biosolids carry elevated risk. We strongly recommend testing through a state-certified lab before selecting a filtration solution. Send us a message — we’ll point you to the right resources.
• What filter actually removes PFAS — not just claims to? +
  Look for NSF/ANSI 58 certification for RO systems, or NSF/ANSI 53 with an explicit PFOA/PFOS reduction claim for carbon-based systems. Independent testing consistently shows RO systems achieve 90–99% PFAS removal. Pitchers and basic faucet filters often remove less than 30% — insufficient as a primary solution for PFAS-contaminated water.
• How often do filters need to be replaced? +
  Under-sink RO systems typically require filter changes every 6–12 months and membrane replacement every 2–3 years, depending on water quality and usage. Whole-house carbon systems vary by tank size and contamination level — typically every 2–5 years. We include a maintenance schedule with every system we size.
• Do I need to test my water first? +
  Testing is ideal but not required to act. If your area has confirmed PFAS contamination or you’re on a private well in a risk area, an NSF-certified RO system is a sound protective decision. If you want to test first, we can point you toward state-certified labs. Either way, send us a message — we’ll help you choose the right solution.
• Does a PFAS filter remove other contaminants too? +
  Yes. RO systems certified for PFAS removal also reduce lead, arsenic, nitrates, chlorine, chloramines, heavy metals, and many other contaminants. Think of PFAS protection as a bonus — not a limitation. It’s one of the most comprehensive water treatment methods available.
• Is bottled water a safe alternative to a PFAS filter? +
  No — and it introduces new risks. Most bottled water brands are not required to test for PFAS, and the FDA has no PFAS limit for bottled water. Additionally, plastic bottles leach microplastics and BPA into the water, particularly when exposed to heat. The average family spends over $1,000/year on bottled water — enough to purchase a certified under-sink RO system that removes 99% of PFAS and lasts 10+ years. Filtration solves the problem. Bottled water relocates it.
