Every figure above is taken from the highest-trust source that carries it and re-derived from that source by a separate check. How we verify product data.
What we could not establish, and why
| Field | Why it is blank |
|---|---|
| identity.family | The approved row merges the separate DGF2 gravity-fed and CKC1 faucet-connected families, so no single honest family name applies. |
| identity.asin | Exact DGF2 Amazon candidates opened to a wooden stand rather than the system; B0FCV2P98Z is retained only as a variant-labelled CKC1-PF commerce destination. |
| certified.certIndexKey | Exact searches of the local certification corpus found no CKC1 or DGF2 join; this is only a fact about the partial local corpus. |
| fit.bathroomsServed | Bathroom sizing does not apply to a point-of-use, batch-filled gravity dispenser, and the manual publishes none. |
| fit.roOutputGpd | The DGF2 uses activated carbon and gravity rather than reverse osmosis, so RO membrane output does not apply. |
| fit.roTankCapacity | The DGF2 has gravity chambers, not an RO pressure tank; the manual publishes no RO tank capacity. |
| fit.pressureRange | The manufacturer manual gives gravity flow but no inlet-pressure range; a retailer's 40–100 psi entry conflicts with the batch-filled design and was rejected. |
| fit.temperatureRange | The manufacturer manual omits an operating-temperature range; the retailer's generic-looking 40–100 °F table entry was not carried over. |
| fit.connectionSize | The DGF2 manual shows a batch-filled chamber with no supply connection; the retailer's 1-inch plumbing value conflicts with that design. |
| fit.requiresDrain | The manual's assembly diagram shows no drain connection but does not state this requirement in words, so the boolean was not inferred. |
| cost.msrp | No current manufacturer system page or manufacturer MSRP for the exact DGF2-B was available; the replacement-element page prices only FDGF2. |
| cost.wasteRatio | A waste ratio is an RO drain-water measure and does not apply to this non-RO gravity-fed system. |
| install.estimatedHours | The DGF2 manual provides assembly steps but no time estimate, and no estimate was invented. |
| install.tools | The manual shows assembly hardware but does not publish a tool list; 'easy assembly' was not converted into a no-tools claim. |
| install.video | Searches found iSpring DGF2 promotional and cleaning videos, but no stable manufacturer installation-video URL was established. |
| comparisons.familyCertNote | No certifier listing was opened that could support extending certification evidence across either DGF2 or CKC1 variants. |
| seo.cluster.primary.kd | The approved build-list row supplies no keyword-difficulty value, and no estimate was substituted. |
| seo.verification | The independent verification loop, not the research pass, stamps this field. |
