AO Smith Invi-U1 - Water Purifier Manual

Introduction

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 and bacteria so they cannot reproduce and are thereby considered inactivated. The A. O. Smith Invi-U1 Water Purifier incorporating UV purification technology produces germ-free potable water for drinking.

How does the A. O. Smith Invi-U1 Water Purifier work?
A. O. Smith Invi-U1 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 in-built storage tank.

Stage 1 – Sediment filter
The Sediment filter is used to remove fine and coarse physical contaminants present in the water. This improves the life of the SCB filter®.

Stage 2 and Stage 3– SCB filter®
This is a dual filter (Sediment and Carbon Block) where Sediment filter first removes fine and coarse physical contaminants present in the water. Then water is passed through Carbon Block, which reduces harmful chemicals like pesticides, volatile organic compounds, residual chlorine etc. It also adsorbs bad taste and odour causing organic compounds from water.

Stage 4 – UV lamp
In this stage water is passed through UV housing wherein UV rays disinfects the water by eliminating water-borne disease causing micro-organisms like bacteria and virus making it healthy for drinking.

Stage 5 – Silver Activated Post Carbon
This is an additional stage of purification to inhibit any potential secondary microbial contamination post UV purification.
