HARDWATER PROBLEMS


Hard water silently damages your home​ causing dry skin, dull hair, and white scaling on tiles and fixtures. It leads to corroded pipes, clogged showers, and spoils expensive appliances.

Protect your health and save on costly repairs with the right solution.

D'Cal - Our Patented Solu​​​​tion

A B O U T   D' C A L

How D'Cal turns hard water into home-friendly water.

                                                 
Hard water silently damages your home – dull tiles, white scaling, rough clothes and frequent appliance failures. D'Cal solves the problem at the source.


Inside the D'Cal cartridge

Each D'Cal unit contains a specially engineered food-grade formulation. When hard water passes through, it converts free calcium ions into a harmless, inactive form. That means:

  • No chalky white deposits on taps, showers and tiles.
  • Reduced scale on geyser rods and washing machine heaters.
  • Softer water feel, brighter clothes and easier cleaning.

10–12 Months Life* Per Unit No Salt, No Electricity, No Backwash  Ideal for Apartments & Independent Homes  ​


Easy 3-step usage

Open your overhead water tank lid.

Place the D'Cal conditioner vertically in the water.

Close the lid – D'Cal now works 24x7 on every drop flowing into your home.

 

*Life depends on incoming water hardness and usage.
