Reverse osmosis (RO) systems are the overachievers of water treatment. They push water through a membrane so tight, even bacteria get claustrophobic. RO is great for point-of-use, like your kitchen sink, but it’s slow—like watching paint dry while you’re thirsty.
For a simpler fix, use NSF-certified filters labeled for bacteria removal. These aren’t your average pitcher filters; they’re designed to catch microscopic stowaways. Just remember to change them on time, or you’ll be filtering water through a germ hotel.
