REVERSE OSMOSIS & DEIONISATION?
Reverse osmosis and deionization (DI) perform the same task of removing impurities from tap water. However, DI purifies water utilizing the principle of ion exchange to remove impurities and replaces them with pure water. In most instances, an RO unit serves as a well-rounded filtration method that removes the majority of impurities; coupled with a post deionization filter, the resulting water is 99.9% pure. Many RO units are available as a combined RO/DI unit or are able to accommodate an add-on DI unit that simply attaches to your existing RO unit.
