Trust, from the inside
How we source, link and date every number
WaterVetted is a normalization project, not a lab. Here’s what that means in practice.
1 · Manufacturer spec sheets
Published removal %, capacity, flow and cartridge cost come from the maker’s official listing or manual, with the URL and date of retrieval preserved on the row.
2 · NSF/ANSI: certified vs claims-only
When we can match the exact model in an NSF, WQA, or IAPMO directory listing, we mark that standard certified and link the source. If the maker only markets a standard on the product page — or the listing does not name this SKU — we keep claims-only. A logo on the box is never enough by itself.
3 · We do not lab-test
We say it plainly and repeatedly. Primary-source testing should come from NSF, the EPA, or a certified drinking-water lab — and we point you there when you need certainty.
4 · Blanks are honest
A missing removal % means the source didn’t state it. We never backfill a guess with a marketing figure.
5 · Dates + versioning
Every row carries an as-of date and the site shows a content version, so you can tell how current a number is at a glance.
