The market is flooded with products that claim to provide clean water and air, so it's important to know the factors you should consider while purchasing them. Should you look at the filter, price, or some other criterion?
Types of Water Purifiers:
Activated Carbon: The carbon granules in these filters are positively charged with silver molecules. Price: Rs 1,800-3,500
Reverse Osmosis Filters: This form of water purification involves forcing water through a semi-permeable membrane, which filters out a select number of water contaminants, depending on their size.
They are known to remove arsenic, nitrates, sodium, copper and lead, some organic chemicals, and the municipal additive fluoride, but are not as effective as the ultraviolet filters against bacteria and viruses. These are essential in areas where contamination levels are high.
Price: Rs 9,000-25,000
