Buying RO / DI - I know nothing

Or you can just use the 20 litre jugs (which are actually 5g, not 6).

All you need is a t-connector to divert the RO water through a "taste" cartridge for drinking water - dead simple. I've installed my RO/DI under the kitchen sink upstairs connected to a tap. I run another line downstairs to laundry room within reach of the aquarium.

As mentioned, you can drink RO/DI to your heart's content. It just tastes bad which is the reason why household units have that taste cartridge which is usually filled with coconut husks. The DI water is instantly re-mineralized when it hits your saliva in any event. It's not some kind of vampire water that'll suck you dry. That misconception comes from the fact that you should NOT keep DI water in a metal container. It will react with the metal and cause rust in the container and contamination of the water.
