What are Deionization or DI filters used for?

Deionization or DI best practices

Deionization or DI filters strip water of 96% to 99% of all impurities. The use of a pre-filtration system, such as a reverse osmosis filter, will greatly extend the life span of the DI filter. DI filters also alter the property of water by removing electrolytes from the water during the filtration process. Avoid drinking water purified with a DI filter because the lack of electrolytes will cause the DI water to strip the electrolytes from your body.

Deionization or DI

Deionization is a process for filtering tap water before it is added to the aquarium. It comes with either separate or mixed-bed resins. The mixed-bed resins are disposable when they are exhausted, whereas separate resins can be recharged, though that requires working with caustic chemicals.
