Here’s the plot twist: a standard pitcher filter won’t touch viruses or most bacteria. Municipal water is already treated, so this rarely matters, but if you’re camping in the woods, don’t rely on your Brita. You’d need a UV filter or a hollow-fiber membrane for that. Think of it as the difference between a doorman and a hazmat team.
Also, filters don’t remove dissolved minerals like calcium and magnesium—the good guys that give water its “body.” Hard water? That’s a job for a water softener, not a filter. As the saying goes, “A filter polishes the stage, but the actors (minerals) stay for the show.”
And harmless sediment? If your tap runs slightly cloudy but clears after a minute, that’s often just trapped air, not dirt. Don’t panic; your filter is fine.
