Here’s where it gets juicy. Filtered water keeps some natural minerals like calcium and magnesium, which is kinda nice for your bones and taste buds. Purified water often strips them out, which is why some brands re-add minerals for taste. You might be paying extra for water that’s been made less natural.
So ask yourself: do you want water that’s been through a spa day (filtered) or a lab test (purified)? Neither is wrong—it’s just preference.
