Overview

The AS-HS48D is Aquasure's 48,000-grain whole-house softener, sized by the company for 3 to 4 bathroom households, built around a digital metered control head and a built-in sediment/carbon/zinc prefilter stage.

Aquasure pairs the resin tank with a triple-purpose prefilter the company says removes 99 percent of contaminants such as chlorine, VOCs, pesticides, and sediment before the water reaches the softening resin. The control head is a programmable digital display that lets you set auto-flush intervals to match your incoming water hardness and usage rather than relying on a single fixed schedule.

  • 48,000-grain resin capacity for 3-4 bathrooms
  • Triple-purpose sediment/carbon/zinc prefilter built in
  • Programmable digital metered control head
  • 5-year extended warranty, lifetime US tech support if registered

Who it's for

Larger households with 3 to 4 bathrooms and correspondingly higher water demand who want whole-house softening plus a built-in prefilter stage in one unit.

Performance notes
