Should you boil the tap water in Iran?
Boiling is a reliable fallback in Iran. A rolling boil for one minute kills bacteria, viruses, and parasites. It won't remove chemical contaminants or lead, though — for those you'd need a filter or bottled water. More on what boiling does and doesn’t remove.
Do you need bottled water or a filter in Iran?
Many visitors to Iran stick to bottled water to be safe, and it's widely available — just check the seal is intact. A reusable bottle with a built-in filter is a lower-cost, lower-waste alternative.
A good filter — ideally certified for microbiological removal, not just taste — makes the tap water in Iran safer to drink. For short stays, bottled water is still the simplest option.
Waterborne illness risk in Iran
The main risk from untreated water in Iran is travelers' diarrhea, typically from bacteria such as E. coli. Being a little careful with ice, unpeeled fruit, and salads rinsed in tap water is the sensible precaution. See CDC food & water precautions.

Water treatment & pipe infrastructure in Iran
Iran relies on municipal treatment, variable upkeep, delivered through a mixed network — aging mains in places. That puts the practical contamination risk between source and tap at medium. Even where water leaves the plant clean, aging mains and rooftop storage are where quality most often slips.
