- Particulate filters strain out solids - the bag and cartridge filters you see on water lines and chemical feeds. Coalescing filters separate liquid aerosols out of gas streams (oil mist out of compressed air, water out of natural gas). Activated carbon pulls out taste, odor, and dissolved organics. Membrane filters (RO, UF, MF) work on a much finer scale to remove dissolved solids and biological material. The right one is whatever matches what you're trying to take out of the stream.
- Micron rating is the size of particle the filter will capture. Choose it by figuring out the smallest particle you need to remove (or the largest you'll tolerate downstream). Common ratings: 100 micron for coarse pre-filtration, 25 micron for general process protection, 5 micron for instrument air and finer process work, 1 micron and below for analytical or final-product filtration. Tighter ratings increase pressure drop and shorten filter life.
- Absolute micron rating means the filter removes 99.9% or more of particles at the rated size (lab-validated). Nominal micron rating means roughly 50-95% removal at the rated size (manufacturer's claim, no standard test). Two filters with the same nominal rating can perform very differently. For anything critical (pharma, sanitary, instrument air for analyzers), spec absolute-rated filters.
