Then there are the countertop filters, like the Berkey or the ZeroWater. These sit on your counter like a proud, sci-fi tank. They use gravity to pull water through filters, and they’re great for emergencies or if you’re extra about water quality.
Rhetorical question time: Would you rather have a filter that removes 99% of contaminants, or one that leaves in the good minerals? Some filters, like carbon blocks, keep calcium and magnesium in—which makes water taste smoother and healthier.

The "I want everything" option
If you’re a control freak (in a good way), consider a reverse osmosis system. It’s the nuclear option, filtering out 99.9% of everything. Your water will be sterile, almost like medical-grade.
But here’s the catch: it wastes a bit of water in the process, and it strips out all minerals. You’ll need a remineralization cartridge to add back the good stuff. It’s like having a coffee machine that makes decaf, then adding caffeine—kind of funny, but worth it if you’re a purist.
