Using the right water for coffee was one of the best tips I learned from multiple sources in order to improve coffee at home. I live in a place in Italy with extremely hard water, so I have a cleaning filter installed that still leaves a series of minerals. Water is good to drink but not to brew coffee.

The solution I’m using now is bottled water, which works really well except for the fact that buying and wasting plastic isn’t ideal at all

Is there any way to obtain good quality water without having a ton of plastic in my bin? I mean I could buy mineral pills or something but still I’d need first to get demineralised water somehow, most likely bottled. So I don’t know really

That won't really reduce hardness. The cheap Brita filters will replace some minerals with salt, but mostly they are there for filtering out pathogens and heavy metals ions/other contaminants with the active carbon.

My tap smells like pool water without the ultra but is otherwise not hard.

I'm in the same boat. Well, not pool water, but it does have chlorine i want to remove, so i use a brita, too. I just know too many people with hard water who try to use a filter to remove it, even though that's not really the way that filters work.
