    • Certification is NSF/ANSI 61 and 372 only, both materials safety listings that make no performance claim, and there is no carbon stage so chlorine and organics pass through.

    NuvoH2O Manor Duo + Sediment Filter

    • The conditioning cartridge chelates hardness rather than removing it, so this system will not change a hardness reading.

    Kind Water SF‑600

    • Its strongest attribute is the maintenance profile: a large conditioning bed that needs no salt, no regeneration, no drain connection and no power, with only the sediment pre-filter as a routine consumable.
    • That is a meaningfully lower running cost than any ion-exchange softener.

    • The Manor Duo threads apply directly to this build because the conditioning cartridge is the same part.
    • Two r/WaterSofteners owners describe the outcome in their own terms: one reports persistent odour after a builder installation and has bypassed the unit, the other reports five years of use that still leaves spotting on glass and fixtures.
    • Neither mentions the sediment stage, which is the part this configuration adds.

    • Favourable brand sentiment in r/homeowners and r/DIY concerns installation and chlorine taste, neither of which this system addresses.
