What is a reverse osmosis water filter?
A reverse osmosis water filter is a type of water filter. (1)
Reverse osmosis water purifiers are able to filter larger particles and inorganic chemicals like heavy metals, salts, and nitrates from your tap water. These filters are directly connected to the plumbing beneath the sink, so the water is filtered as soon as it emerges from the faucet. Some reverse osmosis water purifiers can store a small amount of purified water for later or emergency use. There is also a line that sends any tainted water straight to the drain.
