Can I use water purification tablets or a water filter from the emergency kit?

We recommend boiling your tap water for 3 minutes. Water purification tablets can also make the water safe to use, if you follow the instructions on the packaging carefully. However, using purification tablets or a water filter is usually more expensive. It also takes longer than boiling water and may affect the taste of the water. For these reasons, we recommend boiling your tap water for 3 minutes.
