Harmony Series 48,000 Grain Digital Metered Water Softener

The Aquasure Harmony Series is an entry-priced 48,000-grain digital metered water softener and one of Amazon's best-selling residential units — the value way into true source-level softening. Softening at the source is the most durable fix for dense Asian hair abroad, where water much harder than Taipei or Seoul is what leaves thick hair dull, stiff and coated no matter the shampoo. Being metered, it regenerates on demand, drawing salt and water only when you actually use it rather than on a fixed timer. It suits three-to-four-bathroom homes that want the best value entry into real softening; it is a straight softener, so choose a combination softener-plus-iron unit instead if your water also needs iron removal.
