Quality & Certification

Covers the reduction of contaminants that affect taste, odour and appearance — the part of filtration a customer notices immediately, and the certification retailers and distributors in North America ask for first. The certificate is backed by a seventeen-page material-extraction report, J-00528974, reproduced in full under Reports, and that report carries the only PFAS data we hold: all nine compounds on the NSF PFAS panel came back below their reporting limits, which sit between 3 and 6 ng/L, in the sample and in the control alike. It is worth being precise about what that does and does not measure. It is an extraction screen of the PES membrane material — what the membrane might give off into water — not a rejection test, so it supports no claim about removing PFAS from feed water, and we make none. See the report page for the full panel, including the compounds that were detected.

Verifies that the materials in the product itself contain no more than the lead level the standard allows. This is about what the filter is made of, not what it removes. Our evidence here is an NSF evaluation report rather than a certificate: standard version NSF/ANSI/CAN 372-2024, the sample described as a component - the PES ultrafiltration membrane - screened for lead by XRF under NSF procedure C0513, result Pass, report J-00528976 of 10 September 2025. That covers the membrane material. It does not extend to housings, brass fittings or solder in an assembled device, so it is not a whole-assembly lead-free claim. The three-page report itself is reproduced in full under Reports.

Standard 53 is the one that certifies health-effect removal - dissolved lead, VOCs, cysts, chlorine byproducts. We do not hold a 53 listing, so nothing on this site claims those reductions. If your specification requires one, say so before ordering: a 53 claim has to be tested for the exact contaminant, not inherited from a 42 certificate.

Marking for products placed on the EU market. It applies per model rather than to the whole range, so confirm the CE attestation for the specific model you are ordering — the scan we hold is shown above.

GB/T 19001-2016/ISO 9001:2015, certificate 33925Q15716R0S, issued by ZQHX Certification Center under IAS accreditation with the IAF multilateral recognition mark. The approved scope is R&D and Production of Ultrafiltration Membranes (IAF code 14). Initial approval 24 March 2025, current approval 13 March 2026, expiry 23 March 2028, and the certificate states it stays valid only while the organisation is audited at regular intervals and passes. Read it for what it is: a quality-management-system registration covering how we develop and make ultrafiltration membranes. It is not a product certification, and it does not reach a finished reverse osmosis machine.

Certificate SC-ROHS-2026-08-04, issued 9 October 2026 by CERTIFICATION Center of Riga, Latvia and valid to 8 October 2029, against Directive 2011/65/EU with the IEC 62321 series and EN IEC 63000:2018. The product is described as WATER PURIFIER under the brand ULTRANGE, and its model table lists exactly forty-seven model and type codes, which we can reproduce here: XG-O12; O-A1 through O-A10; O-B1 through O-B8; O-C1 through O-C5; ZH-A through ZH-E; R-A1, R-A2, R-A3; C-A1 through C-A5; C-B1 through C-B5; MY-A, MY-B, MY-C; LS-ZD; and H-1. Sixteen of the nineteen model codes published on this site appear in that table, so most of the certificate is made up of lines we no longer list here. Read it as a scope wider than the current catalogue rather than as a per-model authorisation. It cites one initial type test report, UNICO20261008G50174, but the substance results are inside that report, not on this page - so if your specification needs the actual measured values, ask and we will send the test report rather than the certificate. Published alongside it are the two pages of our own signed EC Declaration of Conformity, CE-DOC20261008G50174, dated Foshan 8 October 2026 and signed by our Technical Manager under the company seal, because under RoHS that declaration — issued under the sole responsibility of the manufacturer — is the document that actually places the product on the market, and the third-party certificate is only supporting evidence. Read its section 3 carefully: it names one directive, RoHS 2011/65/EU, and no other. Note what the document itself says: it was issued on a voluntary basis, does not imply a conformity assessment procedure, and CE marking may be affixed by the manufacturer under its sole responsibility. That is the normal route for RoHS, but it is a declaration supported by third-party paperwork, not a test certificate handed down by an authority. Every product page on this site states whether its own model code appears on that table, so you do not have to take the CE badge on faith.
