
Stage 4 – RO (Reverse Osmosis) membrane
RO membrane contains semi-permeable membrane wherein the water is passed
through the semi-permeable membrane to remove TDS (Total Dissolved Solids) and
heavy metals like mercury, arsenic, lead, chromium, cadmium etc. It also removes
microorganisms like bacteria, virus, protozoa and cysts.

Stage 5 – Silver Activated Post Carbon
Water is passed through Silver Activated Post Carbon which acts as polisher and
enhances the taste of water.
A. O. Smith RO water purifier uses one of the latest technologies that is used in
water purification process. A. O. Smith RO water purifier works under the principle
of RO (Reverse Osmosis) technology which is found to be one of the most effective
process. In this process water under pressure is passed through a semi-permeable
membrane. Purified water is collected for drinking in a storage tank and impurities in
the water are flushed to the drain.
Why water purification is important?
Water purification, today is essential due to the presence of harmful contaminants
present in the water supply. Rapid urbanisation and speedy industrial growth have led to
significant pollutants and contaminants being found in the water supply. Below is a list
of some of the harmful contaminants found today in the water supply which if
consumed in excess can be detrimental to human health.
• TDS (Total Dissolved Solids) like Nitrates, Chlorides, Sulphates etc.
• Pesticides and VOC (Volatile Organic Compounds).
• Heavy metals like Mercury, Arsenic, Lead, Chromium, Cadmium etc.
• Microorganisms such as pathogenic bacteria, virus, protozoa and cysts.
A. O. Smith RO water purifier removes excessive TDS (Total Dissolved Solids) in water
by more than 90%. A. O. Smith RO water purifier reduces heavy metals and removes
pathogens. By this, it ensures you safe and great tasting water.
A. O. Smith RO water purifier has 5 stages of purification system, wherein the water
is passed through the various stages and progressively filtered to get purified water
which is stored in the inbuilt storage tank.

Stage 1 – Pre-filter
The Pre-filter is used to remove physical contaminants such as dirt, dust, soil
particles, turbidity present in the water. This improves the life of the Sediment filter.

Stage 2 – Sediment filter
The Sediment filter is used to remove fine and coarse physical contaminants present
in the water. This improves life of the Pre Carbon filter and ensures efficient working
of RO membrane.

Stage 3
– Pre Carbon filter
The Pre Carbon filter uses carbon block with high adsorbtion capacity which reduces
harmful chemicals including pesticides, volatile organic compounds, residual chlorine
etc., from water. It also adsorbs bad taste and odour causing organic compounds
from water.
