Alright, let’s not pretend it’s a magic wand. A standard whole house filter does not remove dissolved minerals like calcium and magnesium—that’s what a water softener is for. It also won’t zap out bacteria or viruses unless you specifically buy a UV or ultrafiltration model. Know your gear, folks.
And if you have truly sketchy water (like well water with high nitrates or E. coli), you need a system that’s designed for that specific problem. Don’t just buy the first box on Amazon because it looks shiny.
