Criteria for distinguishing between coarse filters and fine filters [Video]

The main differences between coarse filters and fine filters lie in their filtration precision and intended use: Coarse filters are used to remove large particles of impurities such as sand and rust; their filtration precision is relatively low, ranging from several dozen to several hundred microns. They are primarily used in the pre-treatment stage to protect subsequent equipment. Precision filters are even more fine-grained, capable of filtering out smaller particles; their precision can reach several micrometers or even less. They are used to remove things such as bacteria and oil mist from water, and are employed in processes that require high standards, such as in the pharmaceutical and electronics industries. Simply put, the coarse filter is for preliminary screening, to catch larger particles ； Precision refers to fine filtration, used to handle small particles. Which one to use specifically depends on your needs~.
