Should you boil the tap water in Brunei?
In Brunei there's no routine reason to boil tap water before drinking it. Keep boiling in reserve for an official advisory or water drawn from a well rather than the public supply. More on what boiling does and doesn’t remove.
Do you need bottled water or a filter in Brunei?
In Brunei, bottled water is optional — the public supply is safe to drink, so a reusable bottle refilled from the tap is the cheaper, lower-waste option.
You won't need a filter for safety in Brunei — the water's already drinkable. A basic carbon filter is purely a taste upgrade if chlorine bothers you.
Waterborne illness risk in Brunei
Waterborne illness from the public tap supply is rare in Brunei. Ordinary travel food-and-water sense still applies, but the tap water itself isn't the weak link. See CDC food & water precautions.
