UV water purifier:In this technology, water is exposed to UV rays that kill 99% of organisms present in it. It destroys all the pathogens but it does not change the taste of water. Most filters use UV technology with activated carbon that removes chemicals.
Reverse Osmosis (RO) Filters:The RO system offers the multi-stage filtration that combines the active carbon and particle filtration. In this system, the tap water is made to pass through small sized pores that separate minerals and micro-organisms.It improves the taste of water and they are mostly used where the problem with water is the high amount of dissolved minerals.
2) Non-electric water purifiers
Online: These purifiers are portable and need no electricity. It is made of plastic, while the filter candle has a resin filter that should be changed every month.

The RO water purifiers have a special membrane that should be replaced from every 2-3 years.
A water purifier can cost you as less as Rs.1800 and as high as 60000. Features like display panel, rechargeable batteries and a high flow rate are available as you pay more. Best purifiers are from leading brands like Aqua guard, LG and Eureka Forbes.
