### Boiling The most reliable method. Bring water to a rolling boil for 1 minute (3 minutes at altitudes above 2,000m). Kills everything: bacteria, viruses, parasites. ### Water Filter - **Sawyer Squeeze / Katadyn BeFree:** Excellent for travel, remove bacteria and most parasites - **LifeStraw:** Simple and effective for individual use - **GRYNERA bottle:** UV light purification, effective against viruses ### Chemical Treatment - **Iodine tablets:** Effective but taste unpleasant - **Chlorine dioxide:** Better taste, kills Cryptosporidium - **Aquatabs:** Popular and affordable ### UV Light - **SteriPen:** UV light pen that purifies water in 90 seconds - Effective against all organisms but requires clear water (pre-filter if cloudy)

1. **When in doubt, bottle it.** Bottled water is cheap insurance. 2. **Avoid ice** in countries where tap water isn't safe. 3. **Brush teeth with bottled water** in high-risk countries. 4. **Check seal on bottled water.** In some countries, bottles are refilled with tap water. 5. **Consider a filter bottle** (LifeStraw, GRAYL) for eco-friendly, always-safe hydration. 6. **Be careful with salads and fruit** — they may have been washed in unsafe water.

For travelers visiting multiple countries, a high-quality water filter bottle is one of the best travel investments you can make. It pays for itself within a few trips and eliminates single-use plastic waste. --- *Stay healthy abroad with RiskVector.
