Here’s the kicker: all purified water is filtered, but not all filtered water is purified. Filtration is the first step; purification is the grand finale. If your tap water tastes great already, a simple filter is probably your best friend. But if you live somewhere with sketchy pipes or you’re a total water snob, purification is worth the extra bucks.
Let’s compare: filtered water is like a quick wash in the sink; purified water is a soak in a hot tub with jets. Both clean you up, but one’s more thorough—and slower.
