Post-RO Carbon Filter: Last level of purification acts like a polisher and enhances the taste of purified water.
Pre-RO Carbon Filter: Removes chlorine and organic impurities like harmful pesticides. It also adsorbs bad taste and odour-causing organic compounds from water.
Pre-Sediment filter: Pre-Sediment Filter for Heavy Sediment and Particulates (Dirt, Rust, Sand, Silt). It removes fine and coarse particulate impurities and improves life of the Carbon Filter.
RO Membrane: Unique RO technology membrane removes excess TDS, blocks dissolved impurities and chemical contaminants, while retaining essential minerals in the drinking water. It also helps removing dissolved salts, hardness, pesticides and heavy metals like arsenic, lead and mercury.

Physicochemical Parameters
TDS 2000

Total dissolved solids (TDS) refer to the combined content of all inorganic and organic substance contained in a liquid; these are present in a molecular, iodised, or micro-granular suspended form. RO systems are specifically designed to effectively remove TDS to a great extent. Where the TDS level of supply/ground water is high, from 1,000 up to 2,500–3,000, it is recommended that RO systems be installed for drinking-water purpose. A special cellulose membrane cartridge plays a key role in removing TDS from the input water.

As per Indian Standard, an RO system shall reduce TDS level of feed water to less than or equal to 500 mg/l.

  • Al brands reduced the TDS to below the limit specified (500 mg/l) when the input level was maintained at a fixed level.
  • Tata Swach scored highest on this parameter, followed by Aquaguard.
  • Some brands reduced the TDS level to below 100, which is also not desirable due to their reducing the intake level of essential minerals.

General Qualities
Storage Capacity 10

Water-storage capacity should be as declared by the manufacturer.

  • In five brands – Tata Swach, Electrolux, Usha, Aquaguard and Pureit – the water-storage capacity was found to be less than the declared.

Rate of Filtration 12

It is the quantity of output water released from the system in a particular time period. Production rate should not be less than five litres per hour.
