Micron Size Guide for Filtration Systems
Understanding Filter Ratings and Particle Separation
Introduction
Choosing the correct micron size is one of the most important factors in filtration. The micron rating determines which particles are removed and how effectively a system performs.
If you are unsure which micron size to use, this guide explains how filter ratings work and how to select the right one for your application.
For a full overview of filtration, read our guide on what micron filtration is and how it works.
Micron Size Comparison
- 200–100 micron – Coarse filtration, removes large particles
- 50–25 micron – Medium filtration, removes visible particles
- 10–5 micron – Fine filtration, removes smaller particulates
- 1 micron and below – Very fine filtration
Choosing the Right Micron Rating
The correct micron size depends on your material and processing goal.
- Pre-filtration – Use larger micron sizes
- Final filtration – Use smaller micron sizes
- Multi-stage systems – Combine multiple micron levels
Using the correct sequence improves efficiency and prevents clogging.

Common Filtration Setups
Many processing environments use staged filtration:
- Coarse filter → removes larger particles
- Medium filter → refines material
- Fine filter → final clarification
