What Are Water Purification Tablets?

Water purification tablets are small, fast-acting treatments designed to disinfect water by killing bacteria, viruses, and protozoa. Depending on the formulation, they may use chlorine dioxide, iodine, or sodium dichloroisocyanurate to render contaminated water safe to drink. They are widely used during travel, survival situations, or whenever clean water access is uncertain.

Why Are Water Purification Tablets Important?

Accessing safe drinking water is crucial for preventing gastrointestinal infections and dehydration. While bottled water may not always be available, purification tablets offer a reliable alternative that works across freshwater sources such as rivers, taps, tanks, and wells. They are especially important for travellers visiting regions with limited water sanitation infrastructure.

How to Use Water Purification Tablets

Usage varies by brand, but most tablets are added directly to a specified volume of water and left to react for a set period, typically between 30 minutes and 2 hours. Always follow the manufacturer’s instructions for dosage and waiting time. Using filtered water prior to purification can improve clarity and overall effectiveness.

Types of Water Purification Tablets Available

• Chlorine Dioxide Tablets – Effective against bacteria, viruses, and protozoa including cryptosporidium.
• Iodine Tablets – Traditional and fast-acting, though not suitable for people with iodine sensitivities.
• Chlorine Tablets – Commonly used for everyday travel and emergency preparedness.

Statistics, Research, and Expert Information
