Kind Water Systems E-2000 Whole House Salt-Free Water Softener (sediment + ESOFT TAC)

'Kind Scale' is not a Kind product name; the E-2000 is Kind's wall-mounted cartridge salt-free softener for city water (the tank-based SF-600 for well water is $1,705.87; E-3000 with carbon $2,094.10). Price is the maker's listed price ($1,352.93, no compare-at); a site banner reads '18% OFF All Systems ... Discount applied automatically at checkout' (would be about $1,109.40) and Subscribe & Save adds $100 off; the '6'/'12' variants are filter autoship intervals at the same price. Home Depot also sells it (fetch blocked, not verified). Cert caveat: the page leads with 'NSF Certified' and a comparison table claiming 'NSF/ANSI Certified 42, 61, 372', but no Kind or E-2000 listing exists at NSF (CompanyName/TradeName 'kind') or WQA (Kind's only WQA listing is its PRO-RO under NSF/ANSI 58 and CSA B483.1); IAPMO directory not searchable over plain HTTP and no IAPMO listing is cited. TapWaterData says the TAC media is Next Filtration's Next ScaleStop, which WQA lists only to NSF/ANSI 61 (material safety); Kind does not name its media supplier. The '88% scale prevention' and 'removes existing scale' claims have no published test data; Kind's lab-results page covers the E-3000 only (hardness 72.2 to 70.5 ppm, i.e. unchanged by design). The same page promotes a UV add-on as 'NSF/ANSI 55 Certified' but NSF has no Kind UV listing. Manual specs: 25-120 psi, 36-120 F, pH 6.5-9.5, iron and hydrogen sulfide must be 0 mg/L.
