There is a tiny twist. Not all tap water uses the same kind of chlorine treatment. Some water utilities use a compound called chloramine, which is a slower-acting, more stable cousin of plain chlorine. Chloramine is a bit like that friend who says they’re leaving the party but hangs around for another hour—it’s more stubborn.
Boiling will still remove chloramine, but it takes longer—sometimes up to 15 or 20 minutes. If you’re making pasta and you boil water for ten minutes, you’re probably fine. But if you’re just making a quick cup of tea and you pull the kettle right when it clicks off, a tiny bit of chloramine might still be present. Does it matter? For most of us, no. But if you’re raising fish or making baby formula, it’s worth boiling a little longer.
The “Why Should I Care?” Part (Made Fun)
Okay, so why does this matter to you, the person who just wants a good glass of water without tasting a swimming pool? Well, for starters, boiling for chlorine removal is the easiest, cheapest water filter you already own. You don’t need a fancy pitcher or a faucet attachment. Your stove and kettle are basically doing the work. That’s like discovering your old smartphone can also fry an egg—bonus feature!
Does Boiling Water Remove Chlorine From Water? (Quick Answer)
Also, consider your morning coffee. Have you ever brewed a cup that tasted “off,” a little bit like a gym sock dipped in latte? Bad beans aside, that metallic tang can sometimes be chlorine. By boiling your water first, you’re giving your coffee beans a cleaner canvas. Your taste buds will throw a tiny party, and your morning brown liquid will taste more like heaven and less like a chemistry set.
And let’s not forget the grand gift of cooking. When you boil pasta, rice, or potatoes, you’re essentially infusing that starch with whatever’s in the water. If the water smells like a public pool, your spaghetti will, too. By pre-boiling (or just boiling longer before you add the pasta), you’re serving up a side dish of “yum” instead of “municipal processing.”
