Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer with over 20 years of experience in filtration products. Our 1-Year Warranty Wound Cotton Filter Cartridge is designed for industrial water treatment systems, offering reliable performance at a precision of 10 micron and a standard length of 20 inches. Each cartridge is supplied with a Mill Test Report to ensure quality and consistency. With an annual export value of US$5-10 million and serving markets across North America, Europe, Asia, and more, we are committed to providing cost-effective solutions for your filtration needs.

The 20-inch length fits standard housings, and the cartridge is available with or without a center core depending on your requirements.
