About CSM

About CSM

is

the filter brand of Toray Advanced Materials Korea Inc. and the world's No.1 comprehensive manufacturer of filters.

  • has grown into a comprehensive manufacturer of filters, producing RO, NF, UF, MF, and even ion exchange membranes by acquiring a microfilter manufacturing line in 1998 and an ion exchange membrane manufacturing line in 2020 after successfully commercializing reverse osmosis membranes being widely used in seawater desalination, ultra-pure water production, wastewater recycling, etc. in 1994.

    In addition, our self-developed CSM membranes have gained a worldwide reputation for their high quality and reliability, and in particular, our FRM (fouling-resistant membrane) is recognized for its world-leading quality in the wastewater recycling sector. We also produce low-pressure products, ultra-pure water products, seawater desalination products, etc.

  • CSM provides the best service to our customers with our best products and technologies.

    We are continuously providing technical support services to our customers based on our accumulated field experience and technical capabilities, and at the same time, we are doing our best to provide them with prompt technical support and services through our branches in the United States, China, Japan, and India. CSM promises to continue to create a clean and prosperous world where people can smile by satisfying them through the world's best quality, technology, and service.
