What does 5 micron filter mean in practice?
Retains some suspensions at the declared accuracy level of 5 µm and often works as a protection for carbon inserts or membranes.
When does it matter?
The 5 µm value can be nominal or absolute, so two cartridges with the same description do not necessarily have the same effectiveness.
Which solutions are related to it?
The retention coefficient and material are checked, and consumption is assessed based on the pressure difference, flow and water level.
