Introduction Of A.O. Smith UV+UH Water Purifiers X2

UV is a proven disinfection technology used in water purification which delivers micro-biologically 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 X2 water purifier incorporating UV purification technology produces germ-free potable water for drinking. Purified water is collected for drinking in a storage tank.

How does the A. O. Smith X2 water purifier work?
A. O. Smith X2 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 – Sediment filter
The Sediment filter is used to remove physical contaminants such as dirt, dust, soil particles, turbidity present in the water. This improves the life of the Fine Sediment filter.
Stage 2 – Fine Sediment filter
The Fine Sediment filter is used to remove finer physical contaminants present in the water. This improves life of the Carbon block.
Stage 3 – Carbon block
The Carbon block with high adsorbtion capacity 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.
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 microorganisms like bacteria and virus making it healthy for drinking.
Stage 5 – UF (Ultra fine) filter
In the final stage water is passed through Ultra fine filter where it removes deactivated microbial cells and cysts.

Note: The Ball valve comes along with the product as standard accessories.
