There has been rise  sales of in  900Rs good looking water purifiers madeby TATA,HUL .....  these contain  a chemical bulb as water passed thru it it destroys bacteria. 
I checked online and that so called nano tech appeared to be marketing jargon...
actually users will drink the poisonous chemical that is used to kill germs ... i may be wrong .
I agree 4k + models use UV rays ..n are safe.
Any one knows more details on these 900Rs "nano tech"..??
