Silver Impregnated Activated Carbon (SIAC) is an advanced air purification product that combines the adsorptive properties of activated carbon with the antimicrobial characteristics of silver ions. This innovative material utilizes a process where silver ions are infused into the micropores of activated carbon and then fixed at high temperatures. The result is a high-performance purification product capable of decomposing harmful gases into harmless carbon dioxide and water while eliminating various odors. Unlike traditional air purification methods, which rely solely on adsorption, SIAC offers a more sustainable and eco‑friendly approach by actively decomposing pollutants without secondary pollution.
Market Size
Global Silver Impregnated Activated Carbon market was valued at USD 22 million in 2023 and is projected to reach USD 29.34 million by 2030, growing at a CAGR of 4.20% during the forecast period.
In North America, the market size reached USD 5.73 million in 2023 and is expected to exhibit a CAGR of 3.60% from 2025 through 2030. The region’s growth can be attributed to advancements in manufacturing processes, increased adoption of air quality standards, and demand for eco‑friendly purification solutions.
