4 microns is smaller. 600 messh related to openings per square inch. The thickness of screen wire must be reduced from this opening size. For example, 500 mesh screens are rated to have an average 25 microns opening size. For 600 mesh this comes to approximately 21 microns.
Mesh size is usually used in the US. It's just an alternative system used to describe the hole size. For example, 35 mesh (US) is the same as 0.5mm or 500 microns.
The answer depends on whether 100 is more or less than 500!
100 microns is 20 times thicker than 5 microns
It is 4000 microns!

500 to 0 microns
80 mesh size is equal to approximately 180 microns.
There are approximately 37 microns in one mesh of 400.
149 microns is 100 mesh
mesh 500 micron=31 inches=0.0012
I found a Water Quality Standards chart for a geothermal heat pump and one part of it says "Filtered fo maximum 800 microns [800mm, 20 mesh] size." So I would guess its 20.
Microcrystalline cellulose is commercially available in different particle sizes and moisture grades which have different properties and applications.Avicel PH 101Has a nominal mean particle size of 50 microns
If your talking about vacuum 500 microns of Hg is lower.
325 mesh is a sieve with o,o44 mm openings.
Diatoms are microscopic. Diatoms range in size from about 2 microns to about 500 microns or equal to the width of a human hair.
