What this filter does and does not do
The honest summary to read before buying:
- The certification covers PFOA and PFOS. PFNA, PFHxS and short-chain PFAS are not named.
- The 99% figure is the manufacturer's marketing wording; the certified performance data sheet was not readable.
- Sends about 1 litre to the drain per 3 litres produced and needs mains power.
- Filters change every 6, 12 and 24 months, about 175 € a year.
This comparison is a buying aid, not medical advice. The PFAS in your water are on your city's page; this site compares results with its 0.5 ng/L health benchmark for the sum of PFOA + PFOS + PFNA + PFHxS and with the 4 ng/L legal reference. No certified filter guarantees reaching those values.

| Type of evidence | Independent certification PFOA and PFOS are listed among the certified reduced substances (no third-party-lab asterisk) and the certification named is NSF/ANSI 58. The exact certified reduction figure and the challenge concentration were not readable in the performance data sheet, so the 99% figure is the manufacturer's marketing wording. Only PFOA and PFOS are named; other PFAS (PFNA, PFHxS, short chains) are not covered by the claim. |
