If you’re lazy and broke? Get a Brita pitcher. If you’re a taste snob with a budget? Get a faucet-mounted filter. If you’re a water purist who hates microplastics? Get an under-sink reverse osmosis system. And if you’re a total water nerd with walls of money? Go whole-house. The best system is the one you’ll actually use and maintain. Don’t buy a Ferrari if you can’t change the oil.
One more thing: don’t overthink it. You’re already doing amazing by caring. Most people just drink the weird stuff and move on. You’re here, reading about filters, which means you’re 90% ahead of the game. The other 10% is just picking one and enjoying a glass of crisp, clean H2O.
