The space between the woven mesh is measured in microns which is the international symbol "microns".

Decoding

microns = micron or micrometer named also writes fluently "μ".
1 micron equals 0.000 001 meter or 1 millionth of a meter.
The more the difference is small (narrow weaving) at least particles through the sleeve.
Here are the filtration levels, from highest to lowest of Cintropur sleeves:

DISPOSABLE SLEEVES:
1 micron - 5 microns - 25 microns - 50 microns - 100 microns.

THE WASHABLE SLEEVE:
150 microns - 300 microns.

Here the choice of sleeves in line with the type of water:

ROUGHING WATER CHARGED IN WASTE:
150 microns or 300 microns washable sleeve

CLARIFY WATER CHARGED IN SEDIMENTS:
50 microns - 100 microns.

REFINE WATER PRE-FILTERED:
5 microns - 25 microns.

REFINE WATER PRE-REFINED:
1 micron.

  It is therefore advisable to use two to three successive filtrations different level when water is highly charged residue (plant debris and gravel) to prevent rapid clogging of the sleeve which has the highest level of filtration.
