Best affordable RO system for coffee? (www.baristahustle.com)

I live in a super hard water region. So hard in fact that it destroys every appliance despite regular descaling. I've remineralized 5l jugs of demineralized water for years but I feel it's not very sustainable in the long term. Plus demineralized water is not supposed to be safe for human consumption.

I'm looking for an affordable RO system that removes most if not all TDS so I can remineralize it using my favorite recipe.

Do you use any? What are your thoughts? Thanks !

Why is"demineralized" water not safe? How is it demineralized?

Have you thought about getting a water filter for your water supply? Reverse osmosis or ion exchange.

Honestly, no idea. It's written on the jugs that it's improper for human consumption and destined to be used in appliances. It might just be that it's not been certified, or maybe the general processing chain is not food grade. I dunno. Or maybe because it's been demineralized it lacks the chemicals considered "essential" for drinking water.

There are no essential ingredients in water. There is usually so little in water that you can compare a liter water to a small piece of beard. Also note that in some areas the water is naturally extremely soft.

Yeah, well the water here is so hard that using a boiler once is enough to have it all scaled up. Like opaque white in a single use.
