Aquasure Harmony Series 48,000 Grain Digital Metered Water Softener (AS-HS48D): price & specs

The Aquasure manufacturer page (aquasureusa.com) confirms the AS-HS48D Harmony Series 48,000-grain rating, an "ion exchange process," an automatic digital metered control head, and a regular price of $629.99; it does not publish a numeric spec table (no flow rate, salt efficiency, iron ppm, or NSF certification), and a customer review on that page explicitly states it is not NSF 44 certified. FactoryPure (an authorized Aquasure dealer) confirms model AS-HS48D at $629.00 with a spec table listing "48,000 Grains of Hardness," "Cation Resin Media" (ion exchange), 1" NPT connection, 62"H x 10"W x 10"D dimensions, and a "5 Year limited manufacturer warranty" (stated multiple times). No control-head description on either page mentions app/WiFi/Bluetooth connectivity, so smart app control is false. No fetched page states a numeric service flow rate (GPM), salt efficiency, iron-removal ppm, or NSF/ANSI certification, so those keys are left blank. iFilters is referenced only as supplementary EUR pricing/warranty context and was not re-fetched in this verification.
