Little tip about minerals. You get more in one local organic homemade meal than all the water you drink in a year combined. Mineral intake through water is not how we survive. Sure it helps but it's not in the quantities we actually need. You are what you eat. And remember, distilled water is just rain water without the pollution.

Therefore the choice becomes: RO means expensive, proprietary filters that need to be bought forever but are easier to maintain in general.

Distilled means you have to upkeep, improve, maintain the system yourself, clean it. Cost is electricity, Citric Acid and Carbon Filters. Both have their moments to shine.
