What is the size of the particles that the filter captures during water injection into oil wells?

What is the typical size of particles that filters are required to retain when water is injected into oil wells? 5um? Is that too much?
Are you injecting water underground? It should be less than 2.5 micrometers.
The water quality standards for water injection in oil fields can refer to SY/T5329-1994 \"Recommended indicators and analysis methods for water quality used in water injection in clastic rock oil reservoirs\". Currently, it is generally required that the water meet the A1 standard, meaning that the suspended particles in the water are less than or equal to 1 um.
I think it depends on the situation; the quality of water in certain areas determines the level of filtration precision required
