Analysis and Concluding thoughts

As you can see for yourself, not one of the above technologies can claim to be the absolute best when it comes to removing water pollution effectively. But Reverse Osmosis leads other with a significant advantage. Most high-quality RO water purifiers use a combination of filters to remove the shortcomings in their performance. That is the reason why we are seeing RO+UV+UF water purifiers these days which can effectively remove over 99 per cent of the impurities from tap water.

So, when you look for a water purifier online, RO purifiers with additional filters like UV and UF are the best ones to buy. Indian brands like Livpure have been offering these class leading products for some time now. Since the products are manufactured locally, they offer a significant price advantage over foreign brands. Similarly, service and maintenance is also easier with Indian made water purifiers and other smart products because of the brand’s on-ground presence.
