## Methodology

Every row is a verbatim sentence read from the named source's own page through the estate's fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2). 5 of the 37 named sources that could be read published a usable figure; 32 published none and are recorded as not published, never filled in; 1 could not be read (blocked, dead or unreachable) and count nowhere. The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source in USD (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 193 candidate sentence(s) were refused by a reviewer with the reason recorded. Derivation as chartered: the median, minimum and maximum advertised price per treatment type per flow-rate band (GPM) across every manufacturer and direct seller that publishes one, with the annual consumable cost (UV lamp, media rebed, salt) beside the capital price so the five-year cost is the figure nobody publishes; the share of the market publishing a price versus dealer-quote-only (Culligan, Kinetico and the dealer channel are the quote-only half); the NSF/ANSI certification each priced model holds; and the same index read in GB pounds for private supplies and boreholes, giving the GB-US gap per treatment type.
