How to Choose a Micron Rating for Liquid Filtration

Micron rating should not be selected by guesswork. The right choice depends on the particle size you need to remove, the purpose of filtration, liquid properties, filter media, and acceptable pressure drop.

Key Selection Questions

• What liquid is being filtered?
• What particle size needs to be removed?
• What flow rate and pressure drop are acceptable?
• How often can the filter media be replaced or cleaned?
• Is the filter used for pre-filtration, process filtration, or final filtration?

For final product selection, review the application with real operating conditions rather than relying on one specification alone.
