I'm being sold on RO+UV by a water purifier agent. I didn't find any literature that indicated that there are good alternatives to RO+UV. I understand that the RO process is very wasteful and even if I were to reuse some of the wasted water, we'd have very large quantities to bother with.
I wanted to understand from you 2 things:
1) Is it a must to have RO+UV in the typical Bangalore Large Apartment environment?
2) What are the alternatives? If you could even suggest vendors, that would be super useful.
3) How does the large sized canned water supply compare with RO+UV purified water, quality-wise?
Thanks for any advice,
