They offer a convenient and effective way to remove a wide range of contaminants like bacteria, virus, heavy metals and dissolved salts from your water. It is a special type of water purification system, which is carefully designed to remove unwanted molecules from water by forcing it through a semipermeable membrane. This water purification technology can help you drink safe and clean water without compromising the taste. We have curated a list of the best RO water purifiers for home.

What is reverse osmosis?

RO water purifiers are specially crafted to work on the principle of reverse osmosis. It encompasses a pre-filtration stage where the water first passes through pre-filters like carbon filters. It can remove large particles like sand and dirt. Then comes the pre-treated step in which water is forced through a semipermeable RO membrane under high pressure. It allows only water molecules to pass through while eliminating impurities like dissolved salts and heavy metals. After that, water may go through post filters to remove any remaining taste or odour-causing chemicals. Once the purification process is completed, water is then stored in a tank. Some of the best water purifiers for the home also come with a mineralisation stage where essential minerals are infused into the water to enhance the taste and health benefits of the water.
