Filtration Principle: Uses Reverse Osmosis to remove up to 99% of dissolved solids (TDS), chemicals, and germs.

Multiple Stages: Typical machines use a 5 to 7-stage process involving pre-filters, the RO membrane, and post-filters for maximum purification.

Suitable Water Sources: Ideal for hard water, borewells, and tanker water with high TDS levels (>500 ppm).

Automatic Operation: Features auto-start and auto-shutoff, which begins purification when water is low and stops when the tank is full.

Storage Tank: Most models include a built-in food-grade plastic tank (typically 6–10 liters) to store purified water.

Components of a Basic RO Machine

Pre-Filter/Sediment Filter: Removes large particles like sand, dirt, and rust.

Activated Carbon Filter: Removes chlorine, bad odors, and organic compounds.

RO Membrane: The heart of the system, trapping dissolved salts and heavy metals.

Booster Pump: Provides the necessary pressure to push water through the membrane.

Post-Carbon Filter: Polishes the water for better taste before dispensing.

TDS Controller/Mineralizer (Optional but common): Adds back essential minerals for better taste and health benefits.
