NNGYK's 2024 listing reports 59.8 mg/L as CaCO₃ for Katafa in Vas county, which is soft. Halogy is listed with the same value, but the listing does not say whether they share a supply. Scale is minimal at this level, and a softener is generally unnecessary.
Hungarian suppliers report total hardness in German degrees (nk°) or mg/L CaO; the limit is 50–350 mg/L CaO.
