My hair fall reduced dramatically
After 6 weeks with D'Cal, my hair fall reduced by 70%. My skin doesn't feel chalky after bath. Worth every rupee.
Overview
The D'Cal Hard Water Softener is a tank-mount cartridge that softens water for your entire home. Drop it into your overhead water tank — every tap, shower, and appliance receives softer, scale-free water. Zero electricity. Zero maintenance. 12+ months of protection per cartridge.
Key Features
- Softens up to 3+ lakhs litres per cartridge
- 12+ months lifespan with daily use
- 60-80% scale minimization (NABL lab verified)
- Works on borewell water up to 1,200 TDS
- No electricity, no plumber, no chemicals
- Food-grade, BPA-free materials
How It Works
A patented sequestering polymer inside the cartridge bonds with calcium and magnesium ions, preventing them from forming scale on any surface. Water remains naturally mineralised but loses its scale-forming ability.
