Under-sink water purifiers usually consist of a pre-filter, a reverse osmosis membrane, and a post-filter, all installed under the kitchen sink. Pre-filters remove sediment, chlorine, and other contaminants that can affect the taste or odor of the water. The reverse osmosis membrane is the heart of the system as it removes up to 99% of impurities including lead, bacteria, viruses and other harmful substances. An after-filter then adds some healthy minerals and improves the taste of the water.
