What it treats

"Certified" means an independent body (NSF, IAPMO, WQA or CSA) lists this system for that contaminant. "Lab tested" means the maker published a third-party lab report. "Maker claim" means neither.

Contaminant	Evidence
Chlorine	Maker claim	Other systems for Chlorine
Chloramine	Maker claim	Other systems for Chloramine
VOCs	Maker claim	Other systems for VOCs
Sediment	Maker claim	Other systems for Sediment

No claim made for: PFAS, Lead, Iron, Manganese, Hydrogen sulfide, Hardness, Bacteria, Arsenic, Nitrate, Fluoride, Copper, Uranium.

PFAS evidence: No PFAS claim for the E-1000. Kind's lab-results page only has PFAS test reports for its under-sink RO, not this filter.

Owner reports

Kind's own Yotpo reviews rate the E-1000 4.9 from 109 with one leak complaint; reviews of sibling systems on the same plastic manifold (E-3000, E-1000 with UV) repeat two issues: slow leaks at the housings or O-rings and a loud humming or 'foghorn' noise when taps run (brand-level, on-site reviews).

Current model, still sold as the E-1000. It is a wall-mounted 2-cartridge unit on a one-piece manifold, not a media tank; Kind's tank-based carbon filter is the S-500 (separate record). Price is the everyday store price against a $2,062.22 compare-at. Kind advertises NSF/ANSI 42, 61 and 372 certification and 'NSF/ANSI 42 Certified for Chlorine Reduction', but NSF, WQA and IAPMO have no listing for any Kind whole-house filter (Kind's only listing is the PRO-RO under-sink RO at WQA); the claims presumably refer to OEM components and could not be verified. The 'See Lab Results' link goes to SimpleLab Tap Score reports for the E-3000 and the RO, not the E-1000. The carbon contaminant list names hydrogen sulfide, but the manual sets max hydrogen sulfide and iron at 0 mg/L, so hydrogen sulfide is not counted. Operating range 25-120 psi. Kind says about 40% of buyers self-install (2-4 hours) and offers a plumber referral network. Trustpilot profile is claimed but has 0 reviews; BBB A+ (accredited), 2 closed complaints in 3 years. Affiliate: Awin, 60-day cookie, commission not published; an older FlexOffers listing showed 12-16% with a 30-day cookie but is marked not currently offered.
