Product record
Best suited forAn add-on element for Berkey gravity systems. Because it is not certified, prefer a certified reverse-osmosis system when fluoride or arsenic is a documented concern.
Documented standards A standard code in the product record identifies the claimed certification scope. Verify the exact model in the certifier’s current directory before purchase.None listed

Bottom line

Not certified for fluoride or arsenic. Shown for reference; a certified reverse-osmosis system is the evidence-backed choice.

Match factors

  • No plumbing or electricity

Watch-outs

  • No third-party certification for the contaminants it targets

Assessment basis: Certification checked against the NSF, WQA and IAPMO registries (2026-09-23).

Which water problems is this relevant to?The product record lists the following capabilities. Relevance starts with a documented water problem, then the treatment technology, then a product whose exact certified claim matches. These are listed capabilities from the product record: a lead to verify, not the same as an independently certified claim (see certification below).

A capability listed here does not mean that contaminant is present in your water. Find your water system before deciding what treatment is relevant.

Certification and claim scope

A certified standard is an independently tested claim for a specific model. A listed capability above is what the product record or manufacturer states. Treat it as a lead to verify, not proof. Always confirm the exact model in the certifier’s official registry.

No certification standard is documented in this product record. Do not infer performance from the technology name alone.

Installation, ownership, and maintenanceCapacity and upkeep are planning figures from the product record, not guarantees. Actual replacement timing depends on use, influent water, flow, and manufacturer instructions.

Limitations and tradeoffs

  • Targets fluoride and arsenic V specifically; not a PFAS, lead, or hardness solution, and arsenic III may need pre-oxidation.
  • Media exhausts and must be replaced or regenerated
  • Capacity and flow depend on incoming water chemistry
  • Narrower coverage than reverse osmosis

No filter treats every water problem. This analysis does not replace household testing, installation requirements, or the manufacturer’s current performance data sheet.

Manufacturer claims we could not verifyThese appear in manufacturer or retailer material but are not backed by a certification PurityMap could confirm. Treat them as unverified.

  • Fluoride and arsenic reduction are manufacturer-tested only. The PF-2 element is not listed by NSF, WQA or IAPMO.
