Domestic RO water purifiers are sophisticated multi-stage filtration systems designed for household use that remove dissolved salts, heavy metals, chemicals, bacteria, and viruses to provide safe and healthy drinking water. They typically combine reverse osmosis with other technologies like UV and UF for comprehensive purification and often include features to retain essential minerals.

Key Features and Description

Multi-Stage Purification: Most modern domestic purifiers employ a combination of purification methods to ensure thorough cleaning. The typical process includes:
- Pre-filtration: Sediment and carbon filters remove larger particles like dirt, rust, sand, and chemicals such as chlorine and pesticides, which also protects the delicate RO membrane.
- Reverse Osmosis (RO): The core of the system, where a semi-permeable membrane uses high pressure to force water molecules through, leaving behind dissolved solids (TDS), heavy metals (lead, arsenic, mercury), and other microscopic impurities.
- UV (Ultraviolet) Disinfection: In this stage, UV light is used to kill any remaining bacteria and viruses by damaging their genetic core, ensuring the water is microbiologically safe.
- UF (Ultrafiltration): Some advanced systems also include a UF membrane which physically obstructs any lingering bacteria or microorganisms.
- - Post-filtration/Mineralization: A post-carbon filter polishes the water for taste, while a TDS controller or mineral cartridge adds essential minerals like calcium and magnesium back into the purified water to balance the pH and improve its taste and health benefits.
- Design and Build: These units are typically designed to be compact and aesthetically pleasing, suitable for wall-mounting or countertop placement in modern kitchens. They are constructed from durable, food-grade ABS plastic and feature storage tanks (commonly 8-12 liters) to ensure a continuous supply of water on demand.
- Smart Features: Many models come with user-friendly indicators and smart features, such as filter replacement alerts, real-time water purity monitoring displays, and tank-full indicators.
- Water Source Compatibility: Domestic RO purifiers are versatile and can effectively purify water from various sources including municipal tap water, borewells, and tankers, making them ideal for diverse conditions.
