Can polypropylene filter cloth be used for oral liquid filtration

No. Polypropylene filter cloth is usually used for filtration and separation operations in industrial fields, such as chemical industry, environmental protection, food processing and so on. It has high temperature resistance, corrosion resistance and good abrasion resistance. However, filtration of oral liquids is more demanding and requires the use of specially designed medical grade filter media to ensure filtration effectiveness and safety. Medical grade filter media often has more stringent biocompatibility requirements to ensure that it is non-toxic, bacteria-free, particle-free, etc. Therefore, polypropylene filter cloth cannot be used for oral fluid filtration.
