What certifications are listed for these systems?
Aigerri UV Countertop RO: Aigerri uses NSF/EPA-related language on its site, but an independently verifiable model-specific NSF/WQA/IAPMO certification listing was not established during this update. Certification fields are therefore left unknown. Waterdrop N1 Countertop RO System: Retail descriptions use NSF-related wording inconsistently, but I could not verify WD-N1-W in an exact-model NSF, WQA or IAPMO performance listing. Do not mark NSF 58 “Yes” without a matching certification record.
