Purified water may or may not remove the minerals, depending on the method of purification. A simple mechanical filter and a carbon filter can be considered “purification”, but it won’t remove these dissolved minerals. Reverse osmosis is another purification method and does a good job of removing these minerals.
I would avoid commercially available “purified” drinking water since they usually contain added minerals for taste.
Distilled is probably the easiest “purified” water to get since it’s available at grocery stores for $1 or $2 a gallon.

For a good explanation about
reverse osmosis, don't forget to also have a reverse osmosis-based water filter that can remove viruses and bacteria in water.
