What are hydraulic filters rated by?

Explanation:
Hydraulic filters are rated by the size of contaminants they remove, expressed in microns. This rating tells you the smallest particle size the filter is designed to capture with a given level of efficiency. It’s a measure of filtration capability, not how much fluid can pass through (flow rate), the maximum pressure the filter can withstand (pressure rating), or how large the filter’s surface area is (surface area). In practice, a smaller micron rating means the filter can trap finer particles, but it may also introduce more flow resistance and require more frequent replacement.
