It starts with your tap

What’s actually in your water?

Enter your ZIP. We pull your utility’s real EPA testing, grade each PFAS against the health-based limit (with the date + the basis), then show the filter that handles what your water carries — and what still slips through.

  • Your utility’s real measured PFAS (EPA UCMR5), sourced & dated
  • Non-detects shown honestly — never a guessed number
  • No sponsored rankings, no upsells
Source: EPA UCMR5 (2023-2025) + the EPA health-based PFAS limits

How a filter actually works

A good filter catches a lot — but not everything.

In general, here is what a multi-stage cartridge removes at each stage — and what needs reverse osmosis or a softener instead. Your exact water report (by ZIP) is coming next.

IN OUT STAGE 1 STAGE 2 STAGE 3 Sediment mesh rust · sand · 5um Carbon block chlorine · taste · VOCs Catalytic media lead · cyst (NSF-53) Polish
✓ A certified NSF-53 filter catches
Sediment & rust Chlorine & taste Lead Cysts Some VOCs
⚠ Slips through (needs more)
Nitrate · Arsenic · Fluoride→ reverse osmosis
PFAS→ certified PFAS filter or RO
Hardness→ a softener
General guidance — not a reading of your specific utility. The by-ZIP water report is the next release.
The independent registry

Don’t take the box’s word. Search the record.

Every certification, cross-checked against the NSF & WQA listings. We show what’s actually listed — not what the label implies.

Filter Certification Registry

Search any brand, filter part number, or contaminant and see what the official NSF / WQA certification record actually shows -- versus what the box implies. We read 68 filter lines and the NSF/IAPMO/WQA listings so you can verify before you buy.

How to read this: don't take the box's word -- this is what the certification record shows.

  • Listed On the official NSF (or WQA Gold Seal) certification record.
  • Select SKUs Listed for lead, but only on specific premium SKUs -- not the whole line.
  • Via IAPMO/WQA Certified by IAPMO R&T or WQA (legitimate) rather than listed by NSF.
  • Implied only The box implies the claim, but we found no listing on the record -- verify the model.
  • Not on record No published certification claim found (often a sediment / RO-stage element). Not the same as "fails".

No filter in this registry holds a verified NSF/ANSI P473 (PFAS) listing as of 2026-06-24. PFAS-reduction wording you see on a box is not the same as a certified P473 listing -- search "PFAS" below to see which products only claim it, and verify any claim at info.nsf.org.
