A. O. Smith 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 Silver Activated Post Carbon.
Stage 3 – Silver Activated Post Carbon
Water is passed through Silver Activated Post Carbon which acts as polisher and
enhances the taste of water.
Stage 4 – UV Lamp
In this stage water is passed through UV housing wherein UV rays disinfects the
water by eliminating waterborne disease causing microorganisms like bacteria
and virus making it healthy for drinking.
Stage 5 – UFSS filter (For Hot water only)
In the final stage water is passed through Ultra fine SS filter wherein this filter
removes all the particulate and scale matter developed during heating cycle.
How does the A. O. Smith water purifier work?
Introduction
04
UV is a proven disinfection technology used in water purification which delivers
microbiologically safe water. The germicidal lamp inside the UV emits ultraviolet
energy that has the capacity to alter the nucleic acid (DNA) of viruses, bacteria and
cysts so they cannot reproduce and are thereby considered inactivated.
The A.O. Smith water purifier incorporating UV purification technology produces
germ-free potable water for drinking. Purified water is collected for drinking in a
storage tank.
