Top 10 Companies in the Chlorine Dioxide (ClO?) Tablet (Effervescent) for Water Purification Market (2026): Market Leaders Powering Global Water Safety

MARKET INSIGHTS

Global Chlorine Dioxide (ClO?) Tablet (Effervescent) for Water Purification market was valued at USD 285 million in 2025. The sector is projected to rise to USD 485 million by 2034, registering a CAGR of 6.1% between 2026 and 2034.

Chlorine Dioxide effervescent tablets offer a convenient, portable, and highly effective solid form of the oxidant. Upon dissolving in water, the tablets generate chlorine dioxide gas that neutralises bacteria, viruses and chlorine‑resistant protozoa such as Giardia and Cryptosporidium. Compared with conventional chlorine, the approach produces fewer disinfection by‑products and preserves the taste and odor of treated water.

The segment grows steadily as global awareness of waterborne risks rises and demand for reliable point‑of‑use solutions expands across both developing and developed markets. Factors such as outdoor recreation, emergency preparedness, military operations, and humanitarian aid reinforce the need for on‑demand, user‑friendly disinfection.
