Zero Water deionizes water. It removes anything inside of water with an charge, which is a lot of things, but not everything. It gets depleted pretty quickly if there are a lot of minerals in the water and is generally used after RO because RO is cheap compared to DI resin.

What do you use for storage?

For coffee? Just the bags, or freeze if I'm keeping them around for a long time. Tape over the valve and freeze.
