Why Aquus One uses recharge salt?

Aquus One includes an actual ion exchange water softener, not just a filter.

Over time, the softener cartridge captures hard water minerals like calcium and magnesium. As it fills up, its performance gradually decreases.

Salt restores the softener so it can continue working effectively.

Why recharging matters

Keep soft water performance consistent

Maintains the softening function that helps reduce hardness minerals.

Better hair feel

Soft water helps reduce the rough, dry feeling hard water can cause.

Better skin feel

Supports a smoother, less tight post-shower feel.

How often will you need recharge?

Recharge frequency depends on your water hardness and usage.

General guidance:

  • Hard water: weekly
  • Moderate water: every 2 weeks
  • Softer water: monthly

If you notice a drop in soft water performance, it’s time to recharge.

Recharge in a few simple steps:

  1. Open the front cover
  2. Add salt into the tank and let it dissolve
  3. Turn knob to regeneration mode
  4. Run the water for 10-15 minutes

Hands-on time: just 30 seconds or less
