Research Direction

AMC, a variety of harmful substances in the clean room of semiconductor and display processes, lowers the yield of the product and is harmful to workers. Recently, high integration has progressed rapidly in the IT industry, including semiconductors, and the importance of removing harmful substances in clean rooms is increasing day by day. Through technological advancement, EcoProHN is developing high-functioning adsorbents and chemical filters necessary to improve air quality in electronic product manufacturing clean rooms and living environments. We are striving to develop ESG-oriented products to lead eco-friendly management.
