If you have light sulfur (just a whiff, not a punch in the nose), a faucet filter can work. Catalytic carbon is your friend. But you’ll be replacing that cartridge like it’s a roll of paper towels. Expect to pay $30–$60 every 2–3 months.
If the smell is medium or strong? Don’t bother. You need a bigger solution: a whole-house carbon filter, a water softener (if it’s iron-related), or a chemical injection system. Sorry, but a tiny filter can’t fix a big plumbing problem. It’s science, not magic.
So here’s the coffee chat summary: Yes, they exist. No, they aren’t miracle workers. For a faint “eggy” tap, go for it. For a stench that follows you around the house, call a plumber and buy a whole-house filter. Your nose—and your guests—will thank you.
Now, go drink some water that doesn’t smell like a prank. You deserve it.
