For dirty or hard water, materials like activated carbon, KDF, and ion-exchange resins work best. A multi-layer filtration system combining these materials removes chlorine, sediments, bad odour, and hardness-causing minerals. These are ideal for tap and shower filters, making water gentler on skin, hair, and appliances.

Riversoft offers a variety of multi-stage hard water solutions such as the Bliss-15, SF-15 PRO, and DIVA series—for showers and taps. These filters combine KDF, activated carbon, calcium sulfite, Vitamin C, and mineral/alkaline components to reduce chlorine, sediments, and hardness for healthier skin, hair, and appliances.

RO (Reverse Osmosis) is best for reducing TDS and removing heavy metals, while UV is effective at killing bacteria and viruses. For drinking water, a combination of both is ideal. Riversoft filters, however, are designed for external use like showers and taps. They target hard water issues such as chlorine, limescale, and sediment which RO and UV don’t address externally. For a complete solution, use Riversoft for household use and RO+UV for drinking.
