Everyone loves the taste of fresh, purified water, but not many people know which water purification system to choose. One option is using a reverse osmosis (RO) water system. In layman’s terms, reverse osmosis utilizes a semipermeable membrane to remove things such as harmful or taste-altering ions, molecules, and/or sediment such as rust or calcium.
Reverse osmosis systems can include one or two sediment filters, a reverse osmosis filter, a carbon filter, and, in some models, an ultraviolet light to kill microbes. However, there are many systems that claim to be the best RO system on the market, and we’ve put together a list of some of the best reverse osmosis water filter reviews that we could find to help you make an informed buying decision.
